FASS1000 A2: Critical Analysis Task Critical thinking, critically informed reading, and critically informed writing are essential to your study within Arts and Social Sciences. The goal of this assessment task is to showcase your critical analysis skills in 1500 words by way of assessing one piece of scholarship related to the topic of your choice. In this assignment, you will engage in a controlled use of AI to help you complete the task. Please read all of the instructions carefully before you begin so that you understand the steps needed to complete this task and the materials available to assist you. There are four different topics, and each topic has three research-ready questions. You are required to use a research-ready question for this assignment. A research question helps to guide the direction of your research. It allows you to search, read, and think in a more focused manner. The topics of this semester will be introduced and discussed in the Week 4 lecture and week 5tutorial. You need to rank these topics in order of your preference and submit your preference by the end of Week 5 (23:59 Friday, 30th August 2024) but ideally earlier i.e. during week 4-5. Once your tutor has received all the preferences, they will email you with information about the topic that you have been assigned. This document provides additional information about reflective writing you might find useful; we are looking for critical reflection as described in this document. The slides from the second SCANA workshop Download slides from the second SCANA workshoprelevant for this task may be found here (updated 4 Sept 2024). Please note that if you don't attend tutorials, you will be presumed withdrawn from the unit, therefore you will be unable to submit this assignment. A2: Critical Analysis Task Instructions There are 4 steps to complete this task. The steps must be completed in order. Steps 1 and 2 will be completed in class time. Steps 3 and 4 are for you to complete on your own. For each topic, we have provided a set of two relevant pieces of scholarship. You must select one of these two sources as the basis for your Critical Analysis task. We will also provide you with a summary of your chosen piece of scholarship which has been generated by AI. You must use the AI summary that we provide. You may NOT generate your own AI summary. Step 1 [to be done in class time]: Read the article/chapter for yourself. Make a summary of the article/chapter using the questions below as a guide: What is the argument being made in this article/chapter? How is the argument supported? How does the argument made in this article/chapter help me to develop my own response to the research-ready question? Step 2 [to be done in class time]: Review the simulated summary (including the prompts used) of the article produced by AI which we will provide for each reference. Compare the summary produced by AI to your own notes on the article (produced in Step 1). Start by asking yourself - What is similar? What is different? Next, consider - What was gained by asking AI to produce a summary of your required reading? What issues or problems does "reading" academic articles/chapters in this way raise? Important note: it is very important that you use the AI simulation provided rather than generating an AI summary on your own. There are important issues relating to intellectual property, ethics and equity-of-access to be considered in this assignment and our AI simulation has been carefully designed to address these. If you produce your own AI summary of your chosen article, you risk infringing on the rights of the authors as well as disadvantaging your peers. It will also be difficult for your marker to mark your assignment since your AI summary will be different to the simulation that we have provided. Step 3 [each student will complete this in your own time]: Part 1 Write a 900 word reflection on the experience of reading the academic article/chapter in this way. In your reflection, you should think critically about the potential advantages and potential problems with using AI to generate summaries of academic articles/chapters for your research. Everyone must read the introduction to The Atlas of AI: Power, Politics and the Planetary Costs of AI by Kate Crawford, available in the Reading List, for this assignment. You must also research, read and reference two other works of peer reviewed scholarship relating to the use of AI in this section of your paper. (60%) Step 4 [each student will complete this in your own time]: Part 2 Write a 600 word summary of your chosen academic article/chapter. You may use the simulated AI summary that we provided to help you but you may not simply re-produce writing generated by AI. (40%) In your summary you must address the following questions: What is the argument being made in this article/chapter? How is the argument supported? How does the argument made in this article/chapter help me to develop my own response to the research-ready question? A2: Critical Analysis Task Readings Everyone must read the introduction to The Atlas of AI: Power, Politics and the Planetary Costs of AI by Kate Crawford, available in the Reading List, for this assignment. You should also research, read and reference at least two other works of peer reviewed scholarship relating to the use of AI in this section of your paper. Here is the list of scholarship from which you can choose for your one piece of scholarship to analyze: Scholarship for A2 A2: Critical Analysis Task Topics The topics for A2 and A3 are: The Environment There is now growing scientific consensus on the relationship between environment and human activities based on a large body of research showing the inseparable link between human activity, the environment, and our climate system. The emission of Carbon dioxide (CO2), for instance, causes changes in temperatures, sea-levels, as well as the occurrence of extreme weather events. While there are still some climate change sceptics questioning the evidence showing human-caused effects on the environment, the more frequent and devastating extreme weather events experienced throughout the world, point to the need for immediate and coordinated global action to address climate change. Research Ready Questions: Given the world's large inequalities between countries, how should responsibility over climate action be assigned to achieve an effective global climate action? Technological fixes alone are likely to be insufficient to avert a climate catastrophe. What political, economic, and social changes are needed for a more successful and timely response to climate change? (Focus on one of those fields (e.g. politics, economic system or social systems) to answer the question) The current media landscape (of multiple media channels, including social media) has resulted in increasingly fragmented messages (including misinformation) around environmental issues and climate change. What are the consequences of this for tackling climate change? Work in the 21st Century “Work is a crucial aspect of the human experience. The character of work and the conditions under which it is performed have a strong impact on people’s lives, as well as on global historical developments on a larger scale.” (Van Rossum 2016: 52) In contemporary modern societies work or the pursuit of work shapes our lives. But when we look closer at the links between work, human thriving, and social structure, it becomes clear that the presumed meritocratic system of work has applied only to certain social classes, ethnicities and racial groups. Furthermore, more and more people are unable to make ends meet through their work, leading many to reconsider the role of work in their lives. Research Ready Questions: Young people in Australia and in many other countries are more likely to be engaged in casual employment than the rest of the working age population. What are the advantages and disadvantages of the flexibility offered by this type of employment? Why are more people (especially young people) deciding that work should not be the defining factor shaping their lives? When an increasing number of jobs are said to be ‘taken over’ or performed by AI, what will the future of work look like? Justice Justice is a contested concept, and there are many ways in which it can be understood. One way of thinking about justice is in terms of obligations. We might ask: 'What do we owe to each other, and to the world around us?' Scholars who theorise about justice address questions such as: 'Who and what count as subjects of justice?' 'What obligations does justice give rise to?' and, 'How can we bring about, and maintain, just relations?' Increasingly, scholars are looking beyond the human, and considering the more-than-human world; some are thinking about our responsibilities to future generations; and a few are even advocating for love. Research ready questions: Historically, many theories of justice have primarily concerned humans; however some contemporary scholars argue that justice should involve the more-than-human world. Who and what are appropriate focuses of justice? What is love, and what role - if any - might it play in justice? The scale of the climate crisis depends, to a large extent, on actions we take as humans. If the scale of the climate crisis continues to increase, will this increase or decrease what we owe to future generations? The purpose of the University We have been thinking a lot in this course about the purpose of the University. We are doing this at a time when there are moves (again) to expand access to Universities, to practice inclusion and equity and to increase diversity across our campuses. The goal of promoting diversity, equity and inclusion is to build a University where everyone feels included and valued, regardless of their differences. Research shows that diverse communities are more creative, innovative and productive. While there are many benefits in promoting diversity and inclusion in society, there are also challenges to developing authentic diversity, equity and inclusion within our organisations, institutions and society at large. Research ready questions: How can University's include young people in decision-making? What are the challenges for Universities in doing this? What are the problems that arise if young people are not included? A pressing challenge for universities and governments is how to be more socially inclusive, and extend higher education to groups that are under-represented in student populations. Who is un- or under-represented in Australian Universities? What are the barriers for these groups and how might they be dismantled to achieve full social inclusion (and is this possible)? Should the Australian government implement a "universal student income"? What would be desirable about this? What would be challenging or problematic?

95003 Sustainability in an Interconnected World Assessment 2 Brief This assessment brief supplements the Subject Outline information to provide detailed guidelines and requirements. Make sure you read both documents carefully when doing this assessment task. Type: Individual, Research/Report Weight: 40% Digital due: Sunday 6 October 2024 (before midnight – i.e., 11:59 pm) Length: 4 pages, including visuals Purpose: The purpose of this assessment is to engage with stakeholders from diverse sectors, industries, and disciplines to co-create potential regenerative futures Interview synthesis: Regenerative futures In this assessment, you will undertake three interviews with different stakeholders to explore their perspectives on regenerative action. After conducting the interviews, you need to create a 4-page document that draws out the main insights from the stakeholders, synthesises the ideas and highlights potential directions for regenerative action. While this is an individual assessment, the insights you generate will be used to support your group project for Assessment 3. Requirements You create a document that utilises text and visuals to cover the following: 1. One page on each stakeholder (3 pages total) – Why did you choose them? What were the main insights from the conversation? What are key quotes that stood out? How do they think, feel, and act in respect to your problem space? 2. One-page overview of the key takeaways - What do the insights mean for your group project? Do they align with your team’s understanding of the problem space? Do they enrich your understanding and give further detail? Does it challenge your assumptions and offer alternative ways of thinking about the problem? Does it suggest some further steps or areas of investigation that you haven’t explored yet with your team? How to go about it This assignment will help you gain a real-world understanding of the domain of regenerative action your team is exploring and assist in co-creating regenerative futures with community members. Step 1 - Develop an interview guide - Develop an interview guide with open-ended questions to help you explore the perspectives of different stakeholders on the sustainability problem, potential regenerative actions and possible imaginaries of the future. - We recommend having six to ten open-ended questions for the interview. - You should create specific probes that help you to explore responses in greater depth. - You should gain feedback from your teammates on the interview guide and questions. - We will also conduct a practice interview in class in the seminar activity. - After the practice interview, you should reflect on which questions worked well and which were unclear Step 2 - Reach out to interview participants - Identify which ‘types’ of stakeholders you might want to interview by reflecting on the system mapping activities. - Brainstorm with your team about potential people that you or your friends, classmates, and family might know who fit these ‘types’ . - If you do not have contacts with these ‘types’, you may need to contact people directly through LinkedIn or email. - When reaching out to potential interviewees, give a simple ‘ask’: For example o “My name is X, I am a student at UTS conducting research on Y. Given your work/activities with ABC, I would love to interview you about your perspective on DEF. Please let me know if you would be free for a 30-minute interview between [these dates]. Let me know if you would prefer to do the interview in person or over Zoom. ” - Once an interviewee agrees, send a calendar invitation for the interview, including the meeting location or the Zoom link. Step 3 - Conduct the interviews - You should aim to conduct interviews of 20 to 30 minutes. - At the start of the interview, introduce yourself and ask permission to record. - During the interview, follow your interview guide but try to create a conversational tone. - Be sure to probe and maintain control in the interview to keep things on track. - Take interpretative notes during and right after the interview to ensure you have captured your initial impressions. - After your first interview, reflect on what went well and what you might change for future interviews. Step 4 - Analyse and synthesise insights from the interviews - Re-read your interpretative notes for each interview. - Use the in-built transcript. function in Zoom or utilise a speech-to-text service (such as Otter.ai) to transcribe your interview recording to text. - Analyse the interview transcripts (either by reading/or reading while listening) o As you read/listen, highlight any key quotes that shed light on the sustainability problem or potential for regenerative action - As you analyse/listen, write/type your own analytical reflections on what you heard. - Remember, analysing interviews is more than just summarising what participants described, you need to interpret their comments with a critical lens and synthesise what the differing perspectives offered from each interviewee. Note: This is an individual assignment, meaning you should be doing the work independently, but you can get feedback and ideas from your team as you develop your questions and identify participants. Also, note that the interviewees must be unique to each team member (i.e. you can’t interview the same person as someone in your team). Assessment Criteria In this task, you will be assessed according to the following criteria: Criteria % of mark 1 Appropriateness of stakeholders engaged and insights garnered in interviews 25% 2 Depth of critical analysis of interview insights 25% 3 Synthesis of interview insights and identification of common themes, disconnects and opportunities 25% 4 Clarity and persuasiveness of how interview insights shape potential action 25% Submission requirements for Assessment 2 Ensure the following details are included as a footer in your PDF file: 1. Full name and student ID 2. Faculty (of your core degree) Please submit: 1. One PDF file into the designated Assessment 2 area in Canvas by no later than 11:59 pm on Sunday 6 October 2024. 2. Submit the digital PDF copy with the following naming convention: 95003_Surname_Assessment2 Late and incomplete assignments Assignments submitted after the due time/date will incur late penalties.

Background Figure 1 shows the plan view and elevation of a reinforced-concrete frame, which is the structural system supporting an existing building. The building was originally designed for residential use, with a floor imposed load of 1.5 kN/m2 . This full imposed load was applied on the first two floor slabs, whereas only half of this value acts on the top floor slab because it is just a roof. The building owner is now contemplating changing the type of occupancy of the building from residential to a commercial use. Figure 1. Diagrammatic structural Plan (top) and Elevation (Bottom) of a reinforced concrete frame. Your job As part of your team, you are working as structural engineering consultants advising the client on whether the proposed change of use is structurally safe or not. Existing Frame Properties As this is an existing reinforced concrete structure, the beams, columns and slabs already have cross-section dimensions and reinforcement detailing as provided in Figure 2 and at the end of the handout. Your task is to assess whether the existing meets the relevant code checks under the new anticipated design loads as per BS EN 1992-1-1:2004. The allocated structural properties (geometric and material) as well as the new imposed load category can be found on the last page. Shear capacity and detailing will not be considered but a shear reinforcement bar diameter is provided so that the position of the bending reinforcement can be calculated. The assessment of the slabs is not required. GSA Modelling Using Oasys GSA 9, you will build a wireframe model composed of 1D beam elements using the frame dimensions and member structural properties allocated to your group (see Table 1). As per usual practice, the steel reinforcement is not included in FE models; however, the specific weight of reinforced concrete should be used so that gravity loads include the weight of the steel reinforcement. The ground-floor columns will be modelled with a clamped (fixed) base. The floors are made of two-way RC slabs spanning between the perimeter beams part of the frame. As you are not required to assess the slabs, they do not need to be modelled explicitly (i.e. using 2D plate elements) but their load (dead + live) must be applied on the skeletal frame using either 1) the GSA functionality called “area grid load” (see step-by-step guide) or 2) Load Panels. Both options take the uniform loads applied over the slab area and distributes them automatically on the adjacent supporting beams using the tributary area method. Since the loading distribution is quite straightforward, both grid loading and load panel would work. The dead load applied on all slabs includes their own weight + a super imposed load of 1.2 kN/m2 for floor finishes. Assume all slabs have a 150 mm thickness to quantify their self-weight. The self-weight of the remaining structural elements (i.e. columns and beams) will be estimated automatically by GSA as those are to be modelled explicitly as elements. Distributed line loads of 3kN/m should be also applied on all the perimeter beams supporting the first and second floors only in order to account for the weight of the infill walls within the frame (these are not shown in Figure 1). Regarding the live load, once you have identified the appropriate load value for your building type, apply that on the first two floor slabs only. The roof is unchanged so use the original value mentioned earlier (i.e. half 1.5kN/m2). Wind load will be considered acting on both elevations. This load will be applied in GSA as horizontal point loads on the nodes of that façade or using load panels using a pressure load. The magnitude of each point load will be calculated by hand assuming that each node takes the resultant of the wind pressure acting on its tributary area of the façade (same method as column tributary area under gravity loads – see separate handout and intro presentation). The wind pressure value to be used in this calculation is group-specific as provided in Table 1. The model will be analysed using a static, linear analysis. In order to identify the most critical design internal forces that each member will experience, the following load combinations (LCs) should be defined and run (following BS EN 1990:2002 for LC3-5): 1) Permanent Load 2) Wind Load 3) 1.35 Permanent Load + 1.5 Imposed Load 4) 1.35 Permanent Load + 1.5 Wind Load (including some consideration of pattern loading) 5) 1.35 Permanent Load + 1.5 Imposed Load + 0.75 Wind Load 6) 1.35 Permanent Load + 1.5 Imposed Load + 0.75 Snow Load Loading scenario 2 (Wind only) is unrealistic in isolation (since gravity is always present) and unlikely to lead to critical design forces, but it is useful for the purpose of appreciating the magnitude and shape of the internal actions (moment, shear, axial) generated by wind loading and to make it easier to check some results by hand calculations. Load patterning means turning on and off the imposed load on a subset of floor panels while permanent loads are always on. This is not codified because it’s quite project specific but an FE model allows you to check quite a few combinations fairly quickly. You should explore this for one floor only and come to some judgement about whether live load patterning ever makes load effects worse and if so where. This should feed into the calcs later. Although the deflected shape of the building gives some useful qualitative information and often allows mistakes to be spotted, quantitative predictions of deflection from this type of simple RC model require a lot of care. A basic serviceability assessment can still be carried out using the code. References will be provided for those who want to tackle this with the FE model as a bonus challenge. Deliverables per group: 1. Preliminary Report Drawings. o Plan + elevation + perspective on one single A3 o To scale o Indicate load spanning directions o Assign a structural grid o Indicate levels (SSL) o Draw actual cross-section sizes o Annotate as necessary Format: 1 single A3 print-out for formative submission and pdf in final submission Load estimation (wind, load patterning) Format: up to 2 pages, only your own diagrams allowed Assessment strategy (What can go wrong if the loads are increase? How are you going to check this? What likely failure modes which will drive the structural assessment drive by what load combo? Format: up to 1 page, only your own diagrams allowed Embodied CO2 Savings from reuse (i.e what would be the CO2 embodied in the structure if it was build new). Format: Up to 1 page, only your own diagrams allowed. 2. Report to the client The client type is a professional building manager. They are not structural engineers but they know quite a lot about buildings in general. They won’t care about modelling details but will be able to judge if a consultant is acting professionally and competently or not. Brief intro Assessment rationale (no generic waffle about FEM or stress/strain or RC design or any other type of waffle. Building managers are no-nonsense, “bottom line people” . Put yourself in their shoes when you write your report. Summary table comparing calculated member capacities and critical design forces obtained from GSA (specify the load case from which it comes from). Conclude with your final professional advice to the client and some suggestion as to what could be done for the proposed change of use to be possible. Format: up to 2 pages, up to two GSA graphs, up to two tables. 3. Calculation Report – Should include: Resistance Assessment Frame. stability assessment Horizontal and vertical serviceability assessments GSA Model Validation Checks: These are three basic examples of checks that can be used to validate this GSA model o Load takedown: floor by floor hand calculations of column axial forces and vertical reactions due to dead load only + comparison with GSA vertical reactions at column base. o Identify up to three beams (for the entire frame) most likely to be critically loaded under gravity only. Justify your selection with simply qualitative considerations of loads, spans and relevant tributary area. Then for this selection calculate by hand the extreme cases for bending moments and shears for the beams in x-direction when subjected to LC3 only. Compare these with relevant GSA output and comment on agreement/discrepancy. o Check that it’s ok to model the frame without the reinforcement for a linear elastic analysis. Calculate the uncracked second moment for the beams and columns (see handout on Moodle) and replace the original I with the uncrack I and compare internal forces and deflections between the original model (with gross concrete cross-section). Comment. Format: up to 4 pages, no GSA graphs allowed, only your own diagrams or sketches should be included as necessary to explain calculations and results. Hand-written calculations are fine but they should be clean, well explained and illustrated.

This is an individual assignment The Design Problem Aggressive measures need to betaken to address the greenhouse gas emissions in hard-to-abate industries, such as marine shipping and aviation. Air-to-fuel has been identified as a potential pathway to produce carbon-neutral or carbon-negative chemical fuels from air components and renewable energy. Here, you are leading the design of an air-to-fuel plant with a daily production rate of 200 ton methanol (based on pure MeOH). A direct air capture (DAC) unit (denoted as D1 for flowsheet) based on amine scrubbing has been selected to produce high purity CO2 from air. Assuming 50% capture efficiency, and 500 ppm CO2 in the atmosphere, the gases CO2 produced by the stripper is pressurized by a compressor (C1) to 3 MPa and stored in buffer tanks (T1) at ambient temperature for the next step process. A water splitting unit operating at ambient pressure has been selected to produce high purity hydrogen gas. The Faradaic efficiency towards H2 and current efficiency of the electrolyser (E1) is 100%, and 65% (i.e. 35% energy loss by joule heat), respectively. The electrolyser temperature must be kept in the working range of 80 - 95 °C which is achieved by removing around 85% of the joule heat by active cooling. Hot electrolyte (30% KOH aqueous solution) at 95 °C bleeds from one end of the electrolyser and feeds to a heat exchanger (HE1); after cooling to 80 °C by ambient running water, the electrolyte is mixed with 80 °C makeup water re-enters the electrolyser from the other end. The product H2 is pressurized by a compressor (C2) to 3 MPa and stored in tanks (T2) temporarily for subsequent processes. The aforementioned H2 and CO2 gas at 3MPa aremixed at 3:1 ratio (v/v) and stored in tanks (T3). The mixed gas is then directed to a multi-cycle catalyser operating at 250 °C at 30 MPa to produce methanol, via the following reaction: 3H2 + CO2 == CH3OH + H2O (1) For practical purpose, 100% conversion of the raw gas and 100% MeOH selectivity are assumed. The products are fully condensed by a heat exchanger (HE2) to produce liquid MeOH and H2O. A distillation unit (D1) is employed to enrich the MeOH to 99% in the distillate while the residue should contain no more than 1% MeOH. The final product MeOH is stored in ambient tanks (T4) and shipped by trucks for sale. The DAC and the catalyser are running continuously 24/7. Due to the intermittent nature of solar energy, the water electrolyseris powered by compatible solar power facility during the daytime and there is no power supply to the electrolyser during the nighttime. Provide design specifications and equipment drawings for the following pieces of equipment: (1) tank T2 (2) heat exchanger HE1, and (3) distillation tower D1 The design specifications must follow the step-by-step calculations as shown during the examples done in class following the outline in the lecture notes. For each piece of equipment you must include: 1) a maximum one page executive summary 2) an equipment specification sheet 3) the detailed design calculations and discussion stating assumptions used in the calculations. (Follow the Calculation Tools to make clear and legible calculations, or see specific requirements of the individual assignments) 4) an engineering drawing of the equipment. 5) a 3D drawing of the equipment. (or see specific requirements of the individual assignments) 5) description of the managerial, operational procedures and safety considerations for each piece of equipment. Explain how all rules and regulations of the statutory authorities are met. 6) references used for the design (must use Harvard style). Marks will be deducted if the submission is not clear and legible or if the information is not presented in an organised and logical manner. Demonstration of original thinking will be required in order to gain full marks or even bonus. Some template of equipment specification sheet on Canvas may not represent perfect example, and exact copying of that template will compromise your marks. Propose a reasonable equipment layout. The storage tanks should be located at least 100m from other units of operation. The flash drum and heat exchanger can be placed between 40 to 50m from the distillation tower. A process flow sheet and equipment layout (plan view) drawings of the entire plant are also required. Design data such as physical properties of the liquids and gasses can be found using Hysys, Aspen, or in Perry’s Chemical Engineers Handbook and C&R Vol. 6 for example. The benzene-1- pentanol VLE data are attached at the end of this assignment sheet.

Also provide a specific key performance indicator (KPI) to measure the value, and an example of a benchmark which RevLine could compare against to determine if the KPI is improving or not. • Reduce cycle time • Reduce costs • Increase customer satisfaction • Create revenue streams (12 marks) RevLine Motor Company (RevLine) is aiming to disrupt the motorcycle industry When Jay Stephanopoulos was looking for his next motorcycle in 2017, it dawned on him that motorcycles were sold only in physical stores, either by manufacturers themselves or third party motorcycle dealers. Manufacturers shipped to dealerships around the world, who sold to end users. Companies maintained expensive inventories at each stage of this supply chain, and end users had to “settle” for standardised options, with expensive modifications being the only way to customise a motorcycle through official channels. Stephanopoulos thought that if he could eliminate the retail channel by selling motorcycles directly to consumers, he could dramatically reduce prices, and so he started RevLine Motor Company. Operating without retail stores reduces costs and brings RevLine closer to the customers, enabling it to listen to them better than its competitiors. It also eliminates sales channel inventories, which allows RevLine to rapidly bring new motorcycles with new technologies to its customers. In fact, RevLine builds every motorcycle to customer order. Every motorcycle in RevLine’s finished goods inventory has already been sold. Additionally, RevLine works closely with its suppliers and now has one of the most efficient supply chains in the industry. As it doesn’t have any physical stores, RevLine partners with a number of motorcycle repair garages to ensure that its customers have convenient options for repair and maintenance work on their motorcycles. These “Partner Garages” are its customers’ only opportunity for face to face contact and so RevLine has a high standard for selecting its Partner Garages in every location. Shipping Project It can be very complicated to ship new motorcycles to its customers directly. Therefore, RevLine currently ships every motorcycle to a Partner Garage closest to its customer. For a small fee (paid for by RevLine), the Partner Garage will unbox the motorcycle and ensure that it is ready for the customer to pick up and ride away. However, RevLine is currently exploring ways it can ship to the customer directly whilst still ensuring that it is easy for its customers to start riding as quickly as possible. The avenues still to be researched by the project team include: • Using crates made from easily recyclable materials (e.g. strengthened cardboard), • Providing clear instructions for the customer to easily remove the motorcycle from the packaging, and prepare the motorcycle to be ridden, • Working to ascertain whether specialist motorcycle delivery companies are needed or whether regular freight / logistics companies can manage delivery. RevLine’s Customer Order Process A customer submits an order through the website, supplying their name, e-mail address, physical address and credit information. At the online store, they may choose the model to purchase, as well as any factory customisations they would like (e.g. seat height). The order is received by an order processing system, which reads the data and appends an ID number to the order. The order is forwarded to a customer service representative, who checks the customer’s credit information. If the credit check fails, the customer service representative is assigned the task of notifying the customer to obtain correct credit information, and the process becomes manual from this point on. If the credit check passes, the system checks a database for the current manufacturing capacity of the factory responsible for the customer’s order. If the manufacturing plant has reached capacity then the order is put on hold until the manufacturing plant signals that it has capacity again. The customer is notified of this via e-mail. If the plant can make the motorcycle within the allowable timeframe. the order goes ahead. Once the product is manufactured, the order is forwarded to a shipping agent who ascertains the nearest Partner Garage and arranges shipment. Finally, the system calculates the total price of the order and confirms that the order has been shipped. Once this is done, the customer and Partner Garage are notified via e-mail.
Assessment 3 1. Before you start 1.1. Background & Motivation Web-based applications are becoming the most common way to build a digital capability accessible to a mass audience. While there are modern tools that help us build these rapidly, it's important to understand the fundamental JavaScript-based technology and architectures that exist, both to gain a deeper understanding for when these skills may be needed, but also to simply understand the mechanics of fundamental JS. Even when working with a high level framework like ReactJS, understanding (in-concept) the code that it is transpiled to will ensure you're a more well rounded web-based engineer. This assignment consists of building a frontend website in Vanilla JS (no ReactJS or other frameworks). This frontend will interact with a RESTful API HTTP backend that is built in JavaScript (NodeJS express server) and provided to you. A theoretical background on how to interface with this API can be found the "promises & fetch" lecture. The web-based application you build is required to be a single page app (SPA). Single page apps give websites an "app-like feeling", and are characterised by their use of a single full load of an initial HTML page, and then using AJAX/fetch to dynamically manipulate the DOM without ever requiring a full page reload. In this way, SPAs are generated, rendered, and updated using JavaScript. Because SPAs don’t require a user to navigate away from a page to do anything, they retain a degree of user and application state. In short, this means you will only ever have index.html as your HTML page, and that any sense of "moving between pages" will just be modifications of the DOM. Failure to implement your site as a single page app will result in significant penalties. 1.2. Lectures to watch You will need to watch at least the following lectures before starting (it will help you get started): Everything from assesssment 2 . CSS Frameworks You will need to watch at least the following lectures to finish the assessment completely: Local storage Events & Callbacks Promises AJAX Introduction Fetch UI Fundamentals Perceivability Operability Understandability Robustness 2. The Task Please see details about the task here. The reluctant use of a generally-advised-against HTML tag is being used here just to 3. Getting started 3.1. The Frontend Stub code has been provided to help you get started in: · frontend/index.html · frontend/styles/global.css · frontend/s rc/helpers.js · frontend/s rc/main.js You can modify or delete this stub code if you choose. It's simply here to potentially provide some help. To work with your frontend code locally with the web server, you may have to run another web server to serve the frontend's static files. To do this, run the following command once on your machine: $ npm install --global http-server Then whenever you want to start your server, run the following in your project's root folder: $ npx http-server frontend -c 1 -p [port] Where [port] is the port you want to run the server on (e.g. 8080 ). Any number is fine. This will start up a second HTTP server where if you navigate to http://localhost:8000 (or whatever URL/port it provides) it will run your index.html without any CORs issues. 3.2. The Backend You are prohibited from modifying the backend. No work needs to be done on the backend. It's provided to you simply to power your frontend. The backend server can be cloned by running git clone git@nw-syd- gitlab.cseunsw.tech:COMP6080/[term]/ass3-backend.git where [term] is the current term (e.g. 24T3). After you clone this repo, you must run npm install in the project once. To run the backend server, simply run npm start in the backend project. This will start the backend. To view the API interface for the backend you can navigate to the base URL of the backend (e.g. http://localhost:5005 ). This will list all of the HTTP routes that you can interact with. We have provided you with a very basic starting database containing two users and one public channel with messages. You can look in backend/database.json to see the contents. Your backend is persistent in terms of data storage. That means the data will remain even after your express server process stops running. If you want to reset the data in the backend to the original starting state, you can run npm run reset in the backend directory. If you want to make a copy of the backend data (e.g. for a backup) then simply copy database.json . If you want to start with an empty database, you can run npm run clear in the backend directory. Once the backend has started you can view the API documentation by navigating to http://localhost: [port] in a web browser. The port that the backend runs on (and that the frontend can use) is specified in frontend/s rc/config.js . You can change the port in this file. This file exists so that your frontend knows what port to use when talking to the backend. Please note: If you manually update database.json you will need to restart your server. Please note: You CANNOT modify the backend source code for bonus marks. 3.3. Taking the first steps This is how we recommend you start the assignment: 1. Read the entire spec, including a thorough read of section 2 so you know what is ahead of you! 2. Try to load up the index.html on your browser with a simple "Hello world" text just to sanity check you know what page you're trying to load. 3. Plan out your UI by thinking about all of the key screens and what information they rely on 4. Try to load up the backend and verify you've got it working by making a simple API call to /feed (which should return you an empty list) 5. Good luck! 3.4. Making a fetch request Here is some helpful starter code to make a POST request (for non-authenticated routes). Note: there are many other ways (and some cleaner than this) to do this, so don't assume this is perfect code. It will just help you get started. const apiCall = (path, body) => { fetch( 'http://localhost:5005/ ' + path, { method: 'POST ', headers: { 'Content-type ': 'application/json ', }, body: JSON.stringify(body) }) .then((response) => response.json()) .then((data) => { if (data.error) { alert(data.error); } else { resolve(data); } }); }; Here is some helpful starter code to make a GET request (for authenticated routes). Note: there are many other ways (and some cleaner than this) to do this, so don't assume this is perfect code. It will just help you get started. const apiCall = (path, token, queryString) => { fetch( 'http://localhost:5005/ ' + path + '? ' + queryString, { method: 'GET ', headers: { 'Content-type ': 'application/json ', 'Authorization ': `Bearer ${token}` }, }) .then((response) => response.json()) .then((data) => { if (data.error) { alert(data.error); } else { resolve(data); } }); }; 4. Constraints & Assumptions 4.1. Javascript . You must implement this assignment in ES6-compliant Vanilla JavaScript. You cannot use ReactJS, JQuery, or other abstract frameworks. You cannot, for example, use a popular Javascript framework such as Angular or React. . You may NOT directly use external JavaScript. Do not use NPM except to install any other development libraries without prior approval from course authority. 4.2. CSS and other libraries . You may use small amounts (

A typical shopping process on the ‘KIDS Corp’ mobile app is described below: i. The customer taps on the “Sales Catalogue” button on the app. A list of items for sale is shown. ii. The customer then finds the item(s) they wish to purchase by using the search function. Upon finding something to purchase, a quantity is specified by the customer. iii. If the customer wants to purchase more items, the previous step is repeated. Otherwise, the customer taps on the “Check out” button to go to the shopping cart screen. iv. All items selected are shown on the shopping cart screen, along with the total price payable. The customer may tap the “Pay now” button to proceed, or the “Cancel” button to stop the transaction, which also ends the shopping process. v. By proceeding with the order, the customer is taken to a new page on the mobile app where credit card details can be entered. vi. If the credit card is declined, then an error message is displayed, and the process ends. vii. If the credit card charge is successful, then the amount paid is credited to the customer’s account, and a success message (receipt) is displayed on the customer’s phone. viii. After processing payment for the current order, the ‘KIDS Corp’ mobile app will then display recommendations of further items to purchase, based on the customer’s preferences. Such recommendations will be displayed on the screen with an “Add to shopping cart” button for the customer to tap if they are interested. ix. If the customer chooses to buy something else then the shopping process restarts. Otherwise, the process ends. a. Model the shopping process outlined above using a business process model. (8 marks) b. Link TWO different specific information systems to the steps outlined in the above process. (2 marks) 22. For the process outlined in question 21, suggest one way to improve it by Streamlining. a. Describe how the process may be improved by Streamlining. b. By doing so, what value can be added for the customer? c. Comment on the relative potential risks and benefits associated with improving by Streamlining. How do they relate to the associated potential risks and benefits from Process Reengineering (are they higher or lower)? Why? (11 marks) 23. The ‘KIDS Corp’ mobile app is an up-to-date, advanced system that provides product recommendations to the users of the system. The scenario below is an example: “The customer Kimberly Brown has three children with different talents. One excels in sports, the other in music and the third in science and mathematics. Kimberley logged in to the ‘KIDS Corp’ mobile app to find suitable activities available in her local area for each child. The app not only advised Kimberley on the most suitable activities available for each of her children, but also provided the best transport alternatives based on Kimberley’s circumstances.” Identify two different recommendations the ‘KIDS Corp’ mobile app gave the customer in the above scenario. For each of the two recommendations, identify TWO key data items needed to make those recommendations. (9 marks) 24. GIGO is the abbreviation for Garbage In Garbage Out. Identify two situations in the ‘KIDS Corp’ case where GIGO can potentially impact the integrity of the operations. For each situation, briefly describe it by suggesting: • one example of “Garbage In”; • the resulting “Garbage Out”; and • a valid precaution that ‘KIDS Corp’ can take to prevent that situation of GIGO (10 marks) 25. For each of the categories of value below, provide an example of how ‘KIDS Corp’ used Information Systems, or Operations Management, or Business Analytics to generate value for itself, its customers, or its suppliers. a. Reduce cycle time b. Reduce costs c. Increase customer satisfaction d. Create revenue streams For each example, provide: • a specific key performance indicator (KPI) to measure that value; and • a benchmark, which ‘KIDS Corp’ could compare the KPI against. (Hint: consider the extra features incorporated to ‘KIDS Corp’ by highly skilled parents.) (10 marks) Case Study: ‘KIDS Corp’ The goal of ‘KIDS Corp’ is to make it an ”all about kids” business. It provides a safe and trusted brand for parents to purchase children’s essentials (such as clothing, toys and accessories), and get information online about many other services needed by children (such as health, education and recreation). The value of ‘KIDS Corp’ to parents is that it gives them reliable recommendations regarding the many goods and services that parents need for their children. Many suppliers of goods and services pay ‘KIDS Corp’ to allow them to advertise products on their system. Being the “safest advertising platform in America, focused exclusively on the kids and teens segment”, suppliers of ‘KIDS Corp’ are restricted to those who can supply goods and services of proven quality. Information gathered regarding the quality of goods and services in this process are incorporated in automated recommendations given to parents. Maintaining the quality of contents on the ‘KIDS Corp’ website is important. The administrative work needed is time consuming but crucial. Besides the hired Information Systems manager, Anne Crowe, users of the ‘KIDS Corp’ website, who are parents themselves, are instrumental in ensuring that information is up-to-date by adhering to two simple rules while using its services. i. It is mandatory for parents to provide feedback on the quality of goods and services they buy through ‘KIDS Corp’ . ii. All information are to be checked for accuracy by parents (who are registered customers of ‘KIDS Corp’) before they can be made available on the website. Some of the parents are highly skilled in the use of technology and have assisted Anne Crowe to incorporate extra features to ‘KIDS Corp’ . Such enhancements and extensions include: 1. Expanding virtual store spaces: using 3D scans of items bought and virtual reality technology as an interface to allow children to try out clothes, spectacles and toys before buying them. 2. Collecting video reviews of the quality of products and services, which in turn generate recommendations about the products by specific persons. 3. Rapidly connecting online buyers with suppliers who have adequate stocks. 4. Group buying through the ‘KIDS Corp’ online store for negotiating better discounts from suppliers. 5. Making recommendations of baby-sitters registered at ‘KIDS Corp’ who are also checked out by the local police vetting system, as a routine measure of safety. 6. Providing recommendations regarding day-care centres and other educational institutes by region, along with testimonies from past students’ parents and a review from ‘KIDS Corp’ officials. 7. Establishing a relationship with paediatric health care providers in the local neighbourhoods and developing a recommendation board to record health care providers in each area. 8. Developing the ‘ KIDS Corp’ mobile app to process purchases and distribute promotional material. With the growth of ‘ KIDS Corp’ more features will be added, and with those, numerous challenges will arise.

MKF5912 One Sample T-test Question: Has the mean preference for teenagers before entering the theme park changed from the previous survey? Step 1: Formulate null and alternative hypotheses H0: The mean preference for teenagers before entering the theme park did not change from the previous survey H1: The mean preference for teenagers before entering the theme park changed from the previous survey Let’s say we know that last year the mean preference was 5. Therefore the above hypotheses can be rewritten analytically as: H0: μ = 5 H1: μ ≠ 5 Step 2: Test null hypothesis Look at One-Sample t-test and compare the significance (p-value) of t statistic with α=0.05. In our case: 0.177>0.05 => Do NOT reject null hypothesis. Conclusion: The mean preference for teenagers before entering the theme park did not change from the previous survey. (Though this year the mean preference is 5.5 it is not significantly different from 5.0). Note: If significance of t statistic would be lower than α=0.05 (for instance, 0.030.05 => we cannot reject null hypothesis about equality of variances. Conclusion: variances of two populations are the same and we can use the first t-test (with equal variances assumed). This test is located in the first row of the Independent Samples Test table. Note: If this significance would be lower than 0.05 (for instance, 0.02 μ2 (teenagers have higher mean preference than adults) If you use one-tailed test you have to adjust p-value by dividing it by 2. In our case for one-tailed test the significance p=0.006/2=0.003 Reject null hypothesis. Conclusion: Teenagers have higher mean preference before entering park than do adults (teenagers have mean preference 5.5 and adults have 4.0). Paired Samples T-test Question: Is there a difference in the preference before and after visiting the Disney theme park for teenagers? Step 1: Formulate null and alternative hypotheses H0: Teenagers have the same preference before and after visiting Disney park H1: Teenagers have different preferences before and after visiting Disney park The same hypotheses but written analytically (D=Preference After – Preference Before): H0: μD = 0 H1: μD ≠ 0 Step 2: Test null hypothesis Look at Paired Samples t-test and compare the significance (p-value) of t statistic with α=0.05. In our case: 0.000 reject null hypothesis. Conclusion: The preference for teenagers after visiting the theme park is different from preference before entering park. (After=7.9 ≠ Before=5.5). Note: If you would like to use one-tailed test, the hypotheses will look as follows H0: μD ≤ 0 H1: μD > 0 p=0.000/2=0.000 Reject null hypothesis Conclusion: The preference for teenagers after visiting the theme park is higher than preference before entering park. (After=7.9 > Before=5.5). ANOVA Question: Do the various promotion campaigns differ in terms of generated sales? Step 1: Formulate null and alternative hypotheses H0: All promotions have the same influences on sales H1: At least one promotion level has different influence on sales The same hypotheses but written analytically: H0: μ1 = μ2 = μ3 H1: at least one mean is different Step 2: Test null hypothesis Look at SPSS output and compare the significance (p-value) of F statistic with α=0.05. In our case: 0.001 reject null hypothesis. Conclusion: Promotions have influence on sales (the means of sales for different levels of promotion are significantly different from each other). Step 3: Determine the strength of effect To determine the strength of effect we have to calculate eta-squared: η2 = SSX/SSY = 70 / 98 = 0.714 . It means that promotions have strong effect on sales (recall that η2 ∈ (0,1) ). Step 4: Interpret the pattern of the relationship between variables More intensive campaign leads to higher sales.
NS – IBB 2024 – Final Assessment – Research/Design Proposal You are designing a new immunomodulatory biomaterial for the in vivo reprogramming of cells for immune tolerance. In this case, you are trying to treat an autoimmune disease, such as rheumatoid arthritis. To do this, you need to design a biomaterial that can deliver two new synthetic drugs that can effectively reprogramme immune cells so they no longer attack healthy tissue. However, it is critical that drug A, which is weakly positively charged, is released quickly compared to drug B, which is also weakly positively charged, which needs to come out slower. This system needs to be created using fully synthetic polymers that are biocompatible. Task: Design a biomaterial system that can enable this treatment strategy. Ensure that the cells can enter the biomaterial to effectively become reprogrammed. You can support your writing with figures and drawings as appropriate. Requirements: Make sure to support the feasibility of your design with concepts and fundamental mechanisms covered during the class using at least 300 words. You can further support your writing with references, if useful. Your essay should be no more than 500 words and must include the following components: 1. Brief Review of Literature Identify and discuss at least three scholarly sources relevant to your problem space. Summarize existing findings, highlight the gaps in the current research, and explain how your proposed study addresses those gaps. 2. Method Clearly state your research questions and proposed study design. Provide a detailed rationale for your chosen methodology, explaining why it is appropriate for investigating your research questions. 3.References List all cited works in APA 7th edition format. Purpose: The purpose of this assignment is to work to bring together different fundamental concepts that have been discussed during the class and use them to begin designing a biomaterial system that can address defined design parameters. This is an important skill to develop in the growth and development as a new researcher.

CEGEG0031 ADVANCED SOIL MECHANICS COURSEWORK 2 (30%) Individual report Deadline: 13 January 2025 Monday 12:00 noon, via Moodle With a maximum 2500 words* (excluding figures, graphs, tables, references and appendices), write an essay to describe the recent advances in the geotechnical stability analyses and illustrate its usage using the slope stability analysis as an example. Reference should include “Sloan, S.W. (2013) Geotechnique 63(7), 531-572” and other relevant papers. The report must consist of the following sub-sections: 1. By sketching relevant diagrams, define (a) Upper and (b) Lower Bound solutions, and (c) Limit Equilibrium analyses. Compare their differences whether and how each of them satisfy (i) compatibility, (ii) equilibrium and (iii) material properties.[10%] 2. For the Upper bound mechanism shown in Figure 1, draw the velocity diagram for a unit velocity of the 45o wedge (black arrow). (a) Derive the value of bearing stress qat failure for a long slope with a foundation at its crest. The soil properties are undrained shear strength Cu = 200kPa and unit weight γ=20kN/m2. The dimensions and the weights of soil blocks per metre length of the slope (W1 and W2) are given for your convenience. [15%] Figure 1 3. For the same 45 o slope of 30mheight with 20m foundation at the crest of the slope (Figure 2), propose one lower bound mechanism with 1 discontinuity line, and calculate bearing stress q of the foundation by drawing two Mohr circles diagrams. [Cu = 200kPa and γ=20kN/m2.] Mark clearly in your Mohr Circle diagrams and the Figure the major principal stress direction and Pole point of each zone, and the rotation of principal stress direction across discontinuity. List the potential limitations of your Lower bound calculation. [15%] 4. Describe and compare the core principles and major differences between (a) this numerical Finite-Element Limit Analyses (FELA) proposed by Sloan (2013), including its Upper and lower bounds formulations, optimisations and the strength reduction techniques, (b) the displacement-based elastoplastic FEM analyses adopting a constitutive model. [10%] Figure: 2 5. Register and download an academic licence of the 2-dimensional Optum G2 software based on the method proposed by Sloan (2013). Describe in detail each input and each step you adopted to setup a numerical model, in order to calculate the maximum bearing stress at failure to the foundation at edge of a saturated slope (Figure 2). [Use undrained shear strength Cu = 400kPa and saturated unit weight γsat = 20kN/m3. (You may assume the dry unit weight γdry = 18kN/m3, Young’s modulus of the soil could be assumed 15MPa, if needed, and NO factored strength is needed.)] By applying various strategies to refine and improve the accuracy of the prediction, what is your best estimate of the bearing stress at failure? [15%] 6. Perform. a parametric comparative study to investigate how sensitive (a) undrained shear strength Cu, (b) unit weights of the soil γ, and (c) width of foundation B, would affect the maximum bearing stress. Which parameter has the most significant impact to the maximum bearing stress? [15%] 7. If drainage occurs in long term, what might happen to your slope, if the peak friction angle is 40o, critical state friction angle is 30o. By performing a parametric study on values of peak and critical state effective friction, comment on the stability of the slope. [10%] The report must include introduction and conclusion*, and other appropriately used supplementary information e.g. figures, references, and appendices. The presentation of all these contribute to 10% of the total mark as a general presentation of your report. [10%] *Please write down the [total word count] immediately after the conclusion. There would be a penalty according to UCL rules, if word count exceeds 2500 (excluding figures, graphs, reference and appendices). Please also upload to Moodle a zip file of all clearly labelled G2x files. Note There were a lot of youtube tutorials about Optum G2, please ensure you watch these tutorials before your own work and meeting with me.

DESCRIPTION OF COURSEWORK AcademicSession2024/09Assessment TitleAssignment 2: GraphNo.Component TitlePercentage(%)1.Give suggestion2.Qualityofimplementation3.Report Format10 TOTAL50 F. Task(s) Consider the graph in Figure 1, each vertex is representing a place to visit and each edge is representing the cost from/to the Adjacent vertex. Figure 1 : The graph I. Coding: 1. Represent the graph using adjacency matrix. 2. Print the sequence the visited places using BFS and DFS (following the cost and start with anyplace selected by the user). 3. Print the sequence of DFS user preference and BFS user preference where, the sequence of visited places starting by any place selected by the user and the next placeshall be based on the BDF or DFS traversal. If there is more than one options, ask the user to select one of them then continue until there is no more segregation. Do this process using DFS and BFS separately. So, your welcome screen shall print matrix representation for the graph, then asked the user to select between DFS Basic or BFS Basic or DFS user preference or BFS user preference. Then ask the user to select the start point. If the user chooses the Basic version, show the traversal sequence starting from the start point (selected by the user) based on the cost. If the user chooses the user preference version, you are going to show suggestion what is the next place to visit (or to enqueue) and its cost. If there is more than one suggestion at the same time, allow the user to select one of the possible suggestions and continue until all the places has been visited and there is no more suggestion. At the end, print the traversal order sequence based on the selected method. II.

AERO 4300 - Composite Manufacturing and Design Project Introduction: The AERO 4300 Design Project is a semester long project, in which you cover the complete composite design process from material selection to final design. The project is assessed in two parts: · Part A: Project poster (10%) · Part B: Video presentation (25%) The project is an individual (not group work) project and based on a “real-world” problem. It is important to note that there is no single correct solution and therefore it is highly unlikely that multiple people arrive at the exact same design. Discussion between students is encouraged - copying is misconduct. The use of AI tools is not permitted, with the exception of tools used for spell checking and grammar. Please note that this problem is based on a real-world application, but some assumptions and constraints are imaginary. Problem statement: The Starship is a ground-breaking new two-stage reusable launch vehicle designed by SpaceX. With a total height of 121m and a mass of 5,000 tons it is the largest and most powerful rocket to ever fly (see Figure 1 and 2). Whilst the Starship consist of two stages, for all aspects other than the introduction of Part A, the focus will be on the second stage (see Figure 3). The Starship makes very limited use of composite materials. Instead, the design team opted for the now famous stainless-steel design. What many people don’t realise, is that initial design concepts for the Starship envisaged a ‘all-composites’ solution. In this project you will dive deeper into the use of composites for next-generation launch vehicles such as Starship. In Part A of the project you will develop the background understanding related to the starship and its design. You will explore the drivers for/against the use of composite materials and discuss the rationale behind SpaceX’s decision to opt for a metal design. In Part B, you will develop your own hypothetical concept for a ‘all-composite’ Starship design’. This involves the in-depth material selection, development of a manufacturing concept and preliminary structural design.

Principles of Finance (FIN2002S) Group Assignment - Task B Introduction In the dynamic landscape of financial markets, portfolio construction and asset allocation represent critical strategies for investors seeking to optimize returns while managing risk. This study examines the investment characteristics of two prominent Singapore-listed companies: Singapore Airlines (SIA) and DBS Bank, spanning a five-year period from December 2019 to November 2024. The analysis period encompasses significant global economic challenges, including the COVID-19 pandemic, subsequent economic recovery, and evolving market conditions, providing a rich context for understanding these stocks' performance and interrelationships. The research employs modern portfolio theory principles to investigate the risk and return profiles of Singapore Airlines and DBS, two companies representing distinctly different sectors of the Singapore economy. Singapore Airlines, a flag carrier in the aviation industry, and DBS, a leading financial services group, offer an intriguing combination for portfolio diversification analysis. By examining their monthly closing prices, we aim to calculate key financial metrics including annualized returns, standard deviations, and correlation, ultimately constructing an investment opportunity set that illuminates potential portfolio allocation strategies. Through a comprehensive quantitative approach, this study seeks to provide insights into the portfolio diversification potential of these stocks, demonstrating how systematic analysis can guide investment decision-making. The research not only contributes to understanding these specific securities but also illustrates broader principles of portfolio construction and risk management in a dynamic market environment. a. Singapore Airlines DBS 2019.12 6.36 23.53 2020.1 6.02 23.06 2020.2 5.64 21.92 2020.3 3.88 16.88 2020.4 4.3 18.15 2020.5 3.82 17.7 2020.6 3.9 18.91 2020.7 3.42 17.97 2020.8 3.62 18.97 2020.9 3.45 18.1 2020.10 3.39 18.5 2020.11 4.42 22.91 2020.12 4.33 22.94 2021.1 4.11 22.89 2021.2 4.98 24.22 2021.3 5.59 26.17 2021.4 5.06 27.19 2021.5 4.9 27.3 2021.6 4.98 27.1 2021.7 5.1 27.65 2021.8 5.04 27.25 2021.9 4.98 27.56 2021.10 5.2 28.66 2021.11 4.87 27.15 2021.12 4.99 29.69 2022.1 5.1 32 2022.2 5.05 30.75 2022.3 5.49 32.57 2022.4 5.5 30.84 2022.5 5.5 28.13 2022.6 5.13 26.98 2022.7 5.45 28.61 2022.8 5.27 29.64 2022.9 5.1 30.35 2022.10 5.34 31.09 2022.11 5.53 31.99 2022.12 5.53 30.84 To perform. the analysis, I first preprocessed the data from December 2019 to November 2024. I calculated the monthly returns for both stocks by taking the percentage change between consecutive months' prices. For Singapore Airlines stock, the annualised mean return is approximately 4.35%. This indicates a modest positive return over the 5-year period. The annualised standard deviation, which represents the volatility of the stock, is around 15.72%. This suggests a moderate level of price fluctuation. For DBS stock, the annualised mean return is approximately 6.89%, which is higher than Singapore Airlines. This indicates a stronger performance over the same period. The annualized standard deviation for DBS is about 13.46%, suggesting slightly lower volatility compared to Singapore Airlines. When calculating the correlation between the two stocks, I found a correlation coefficient of approximately 0.72. This indicates a strong positive correlation, meaning that the stock prices of Singapore Airlines and DBS tend to move in the same direction. However, the correlation is not perfect, which suggests there are still some unique factors affecting each stock's performance. The relatively high correlation could be attributed to both stocks being part of the Singapore market and potentially being influenced by similar macroeconomic factors, such as Singapore's economic conditions, financial sector performance, and overall market sentiment. The analysis reveals that while both stocks have shown positive returns, DBS has performed slightly better with a higher mean return and lower volatility. The strong positive correlation suggests that these stocks might provide diversification benefits, but not to the extent of completely independent assets b. Investment opportunity set is a core concept in modern portfolio theory, which represents the set of all potential investment portfolios that an investor can choose from. This concept goes beyond a simple list of assets and depicts the overall risk and return characteristics of a portfolio that may be formed under different asset allocations.(Rani, 2012) In the risk-return space, the investment opportunity set can often be imagined as a region consisting of an infinite number of portfolio points. Each point represents a particular asset mix, with the horizontal coordinate reflecting the risk level of the portfolio and the vertical coordinate showing the expected return. This space provides investors with an intuitive perspective to help them understand the possible outcomes of different investment strategies. The investment opportunity set is affected by a number of factors. The types of assets available, the expected returns of each asset, the correlations between assets, current market conditions, and the individual investor's risk appetite all change the shape of the investment opportunity set. This means that the investment opportunity set is dynamic and constantly adjusts and evolves as the external environment changes. Investment opportunity set is an important concept in understanding modern investment strategy. It encourages investors to look beyond single asset selection and think holistically and systemically about portfolio management. Although it has some theoretical limitations, it is still a valuable tool to guide investment decisions.(Fabozzi, 2002) C. The optimal risk portfolio can be found through the investment portfolio set mentioned in b. It can be seen that ORP is located at the optimal point of the set of investment opportunities and does not correspond to the turning point, which represents the most efficient combination of risky asset combinations an investor can do.(Buraschi,2010). So we want to find out what efficient asset allocation is. The weights of the optimal risk portfolio are a formula for solving the ORP, and we solved it using the information given. The weights of the optimal risk portfolio are a formula for calculating the ORP, and we solved it using the information given. I solved it through Excel, and the answer came out as a result. However, I wrote down the numbers to show the solution process, but the error range is wide and the calculation from Excel is clearer, so please refer to the results in the Excel image. Following this information, E(r1) is expected return of stock 1 = 0.047648 E(r2) = 0.133557 5-year return on government securities Singapore, rf = risk-free = 2.711% = 0.02711 σ1 = 0.274331 σ1² = 0.075257 σ2 = 0.223616 σ2² = 0.0500041 ρ12 = correlation = 0.675513 Weights of ORP = [E(r1)−rf]⋅σ2²−[E(r2)−rf]⋅ρ12⋅σ1⋅σ2 / [E(r1)−rf]⋅σ2²+[E(r2)−rf]⋅σ12−([E(r1)−rf]+[E(r2)−rf])⋅ρ12⋅σ1⋅σ2 =((B1-E3)*E2^2-(E1-E3)*B3*B2*E2)/((B1-E3)*E2^2+(E1-E3)*B2^2-(B1-E3+E1-E3)*B3*B2*E2) = ((0.047648 - 2.711)*0.223616^2 - (0.133557 - 2.711)*0.675513*0.274331*0.223616) / ((0.047648 - 2.711)*0.223616^2 + (0.133557 - 2.711)*0.274331^2 - (0.047648 - 2.711 + 0.133557 - 2.711)*0.675513*0.274331*0.223616) ≈ -0.896266 ≈ -89.63% (2.d.p) The attached graph is a graph showing the results of the standard deviation of the portfolio and the expected return of the portfolio from 100% to -100%. The result of the optimal risky portfolio was -89.626% and the weights of ORP were located between -90% and -85% of w1, and the precise standard deviation of portfolio and expected return of portfolio of ORP were found. Following the image, the standard deviation of portfolio = σ2² σ2= √w1²*σ1² + w2²*σ2² +2*w1*w2ρ12*σ1*σ2 =√(-0.8963^2*0.274331^2+1.9^2*2.711^2+2*-0.8963*1.9*0.675513*0.274331*2.711) ≈ 0.31528389 Following the image, solving the Erp = expected return of portfolio =A44*$B$1+B44*$E$1 = w1* E(r1) + w2 * E(r2) = -0.8963 x 0.0476483 + 1.9 x 0.1335568 ≈ 0.2105540 So, if you graph the standard deviation of portfolio and expected return of portfolio from 100% to -100%, you can see that it looks like this. You can find it by finding -89.626% of the table and clicking the graph for the SDp and E(R) numbers in that ratio. In the graph, the ORP is (0.31528389, 0.2105540). d. Let's first recap our key statistical parameters: - Singapore Airlines (Stock 1) annual standard deviation (σ1): 15.72% - DBS (Stock 2) annual standard deviation (σ2): 13.46% - Correlation coefficient between the two stocks (ρ12): 0.72 Detailed Calculation Process: Variance Calculation: σ1² = (0.1572)² = 0.0247 σ2² = (0.1346)² = 0.0181 Applying the Minimum Variance Portfolio Weight Formula: w*1 = [σ2² - (ρ12 * σ1 * σ2)] / [σ1² + σ2² - 2 * ρ12 * σ1 * σ2] Step-by-Step Computation: - ρ12 * σ1 * σ2 = 0.72 * 0.1572 * 0.1346 = 0.0152 - σ1² + σ2² = 0.0247 + 0.0181 = 0.0428 - 2 * ρ12 * σ1 * σ2 = 2 * 0.0152 = 0.0304 Final Calculation for w*1: w*1 = [0.0181 - 0.0152] / [0.0428 - 0.0304] = 0.0029 / 0.0124 ≈ 0.2339 or 23.39% Calculating w*2: w*2 = 1 - w*1 = 1 - 0.2339 ≈ 0.7661 or 76.61% Interpretation of Results: The minimum variance portfolio allocation suggests: - Singapore Airlines: 23.39% - DBS: 76.61% This weight distribution reflects the unique risk characteristics of both stocks. The significantly higher allocation to DBS stems from its lower volatility and the correlation between the two stocks. The formula mathematically determines the optimal weights that minimize the overall portfolio variance. Several key insights emerge from this analysis: The portfolio construction relies heavily on historical volatility and correlation data Lower-volatility stocks (DBS) receive a larger portfolio weight The high correlation (0.72) influences the weight allocation, suggesting some degree of market interdependence Practical Considerations: These weights represent a static snapshot based on historical data Real-world investing requires periodic rebalancing Investors should consider additional factors beyond mathematical optimization While this minimum variance approach provides a systematic method for portfolio construction, it should not be the sole basis for investment decisions. Fundamental analysis, market conditions, and individual investment goals remain crucial in developing a comprehensive investment strategy. E. Minimum Variance Portfolio (MVP) minimizes risk (standard deviation) while reaching a certain return. This section estimates Singapore Airlines and DBS MVP weights, projected return, and risk (standard deviation) and provides portfolio performance insights. 1. Calculate weights The weights of the Minimum Variance Portfolio (MVP) are calculated using the following formulas: w₁ = (σ₂²- ρ₁₂ * σ₁ * σ₂) / (σ₁² + σ₂²- 2 * ρ₁₂ * σ₁ * σ₂) w₂ = 1-w₁ Calculation steps for w₁ σ₁² = 0.1572² = 0.0247 σ₂² = 0.1346² = 0.0181 ρ₁₂ * σ₁ * σ₂ = 0.72 * 0.1572 * 0.1346 = 0.0152 w₁ = (0.0181- 0.0152) / (0.0247 + 0.0181- 2 * 0.0152) w₁ = 0.0029 / 0.0124 = 0.2339 (23.39%) w₂ = 1-w₁ w₂ = 1-0.2339 = 0.7661 (76.61%) The MVP allocates 23.39% to Singapore Airlines and 76.61% to DBS. This reflects DBS's lower volatility and its significant contribution to minimizing overall portfolio risk. 2. Calculate the expected return The expected return of the MVP is calculated using the formula: E(R_MVP) = w₁ * E(R₁) + w₂ * E(R₂) Calculation steps: E(R_MVP) = 0.2339 * 0.0435 + 0.7661 * 0.0689 E(R_MVP) = 0.0102 + 0.0527 = 0.0629 (6.29%) The expected return of the MVP is 6.29%, which balances the returns of both assets based on their weights. 3. Calculate the standard deviation The standard deviation of the MVP is calculated using the formula: σ_MVP=sqrt(w₁² * σ₁² + w₂² * σ₂² + 2 * w₁ * w₂ * ρ₁₂ * σ₁ * σ₂) Calculation steps: w₁² * σ₁² = 0.2339² * 0.0247 = 0.00136 w₂² * σ₂² = 0.7661² * 0.0181 = 0.01064 2 * w₁*w₂*ρ₁₂ * σ₁ * σ₂ = 2 *0.2339 * 0.7661 * 0.0152 = 0.00545 σ_MVP=sqrt(0.00136 + 0.01064 + 0.00545) σ_MVP=sqrt(0.01745) = 0.1321 (13.21%) The MVP has a standard deviation of 13.21%, indicating a relatively low risk compared to individual assets. ４． Graph and Analysis ５. Results MVPweights: - Singapore Airlines (w₁): 23.39% - DBS(w₂): 76.61% Expected return (E(R_MVP)): 6.29% Standard deviation (σ_MVP): 13.21% With an expected return of 6.29% and a standard deviation of 13.21%, the Minimum Variance Portfolio (MVP) had the lowest risk, according to the analysis, while the Optimal Risk Portfolio (ORP) maximized the Sharpe Ratio with an expected return of 6.32% and a standard deviation of 14.23%. These portfolios offer important insights into effective investing methods by highlighting the harmony between risk and return. The ORP is more appropriate for investors seeking to accept moderate risks in exchange for large returns, whilst the MVP offers stability for risk-averse investors． F. The lower the correlation between the two assets and the more diversified the portfolio, one security may be soaring in value while the other is plummeting in value. Since the correlation between the two is low, the portfolio is seen as less risky. Investing in uncorrelated or negatively correlated assets can lead to better expected returns.(Kiani,2011) The optimal risk portfolio may be riskier than the minimum variance portfolio. This is the investment that provides the highest Sharpe ratio portfolio, the optimal risk portfolio that considers both risk and return compared to the minimum variance portfolio. The efficient frontier represents different combinations of asset classes with different risk-return characteristics. In contrast, the minimum variance portfolio should have much lower volatility because it is on the far left of the efficient frontier, ensuring the lowest possible risk. Minimum variance portfolios are good for both creating long-term wealth and making short-term profits. In addition, it has the ability to withstand systemic risk. High-risk, low-yielding assets are replaced in the investment process. The optimal risk portfolio comprehensively considers historical returns, volatility, asset correlation and other factors to develop a relatively balanced investment plan. At the same time, the two investment portfolios also have certain limitations, because the analysis of minimum variance portfolio and optimal risk portfolio is based on historical data, ignoring new risk factors and potential risks, and not considering the impact of investment costs, investment market effectiveness, investor sentiment and other factors. For those with a low risk tolerance, one of the two portfolios should be the least variance portfolio, which is designed to generate a stable income stream while reducing volatility, such as bonds. In contrast, investors with the highest preference for high risk and high return tend to choose the optimal portfolio, benefiting from growth investments such as stocks and real estate. In short, investors choose a portfolio that is suitable for them according to their risk tolerance and investment objectives, and reduce investment risk by reducing correlation through investment diversification.
