ELEC9703 Microsystems Design &Technology Term 1, 2025 Assignment 1 Due on 11:59pm 28th of March 2025 Question 1 (50 marks) The fabrication of a pressure sensor requires the fabrication of a 20µm membrane. In using a 400mm diameter orientation silicon wafers, the average thickness of a batch of wafers is 600µm with a variation of ±20µm. a) Suppose you decided to use TMAH (25%) as an anisotropic wet etchant at 70°C to form. the pressure sensor with a 400µm x 400µm square diaphragm of 20µm thickness. Anisotropic etching characteristics of TMAH can be obtained from the Prof. K Sato’s paper: “Anisotropic etching rates of single-crystal silicon for TMAH water solution as a function of crystallographic orientation”, Sensors and Actuators A: Physical; Vol.73, Issue 1-2, 1999, pp131-137. (i) Assume you decided to achieve a 20µm thick diaphragm by timed etch. For a plain double side polished 600µm thick 400mm orientation silicon wafer, what is the required mask size opening to be patterned on the backside of the wafer, to achieve the desired pressure sensor diaphragm size, and what is the required etching time? (20 marks) (ii) With this etch time, what is the range of the final diaphragm sizes you will obtain over a batch of such wafers? (5 marks) (iii) Suppose that during the photolithography step, the mask was misaligned to the major flat by 1.5°. What will be the final diaphragm thickness and size if the same etch time obtained in part (i) was used. State assumptions made. Provide a sketch of the relation between the mask and the final opening on the backside of the wafer. (15 marks) (b) Suggest what approach you would like to adopt so that repeatable diaphragm thickness from one process run to another can be achieved. Give a brief description of the process steps. (10 marks) Question 2 (50 marks) Below in Figure 1(a) and (b) are illustrations of the top and cross-sectional views of the analogue device accelerometer. The accelerometer has a shuttle mass (1) suspended by two springs (2) that are anchored (3) to the substrate at their other ends, two sets of interdigitated fingers with one end attached to the shuttle mass and another one anchored to the substrate, and electrical connectivity to the shuttle mass (Vx) and the anchored fingers of the two sets of the interdigitated fingers (Vs and -Vs). C’1 and C’2 are the capacitances defined by the overlapping fingers in each of the two sets of the interdigitated fingers and are of the same value when no acceleration is measured. When the device is subjected to an acceleration, the shuttle mass will experience a force and is displaced to increase the distance (decrease capacitance, C’1) between the overlapping fingers of one set of the interdigitated fingers and decreases (increase capacitance, C’2) for the other. The difference in the capacitances, which is proportional to the acceleration, produces an output voltage Vx that can be further processed. The accelerometer is to be fabricated using POLYMUMPS process. POLYMUMPS is 3 structural polysilicon layers (POLY0, POLY1, and POLY2) with 2 sacrificial SiO2 layers and one metal layer (Au/Cr). The polysilicon layers are deposited by LPCVD process. Note that there is LPCVD Si3N4 isolation layer between the substrate and other deposited layer. (i) Which layers of the three structural polysilicon layers (POLY0, POLY1 and POLY2) do you use to form. each component of the accelerometer? The shuttle mass, the interdigitated fingers, the anchors, and metal pads (10 marks) (ii) Describe the possible fabrication process steps to realise the accelerometer. You may use figure 2(b) to illustrate each fabrication step. Your answer for each step should be as detailed as possible. For example, is etching step dry (plasma) or wet? What etching recipe would you possibly use? (30 marks) (iii) What is the reason for having holes on the shuttle mass? Is that necessary? (5 marks) (iv) The accelerometer operates in vacuum. Describe the possible additional fabrication processing steps required to achieve this. (5 marks) (1) Shuttle mass; (2) Spring; (3) Anchor; (4) Metal pads; (5) Interdigitated fingers (a) (b) Figure 1: (a) top; (b) cross-sectional view of the accelerometer.
CS 168 Spring 2025 Project 3: Transport In this project, you will implement a subset of the TCP protocol. Your implementation will provide reliability, though it wonʼt include congestion control. Lectures needed for this project: Lecture 11 (Reliability), 12 (TCP Implementation). You can work on this project alone, or with one partner. You can keep the same partner from an earlire project, or choose a different partner. Reminder: Our course policies page has a collaboration policy that you must follow. Setup Operating System Installation This project has been tested to work on Linux and Mac. If youʼre on Windows, we recommend using WSL. Python Installation This project has been tested to work on Python 3.7. (It probably works on newer versions of Python as well, but use at your own risk.) If you run python3 --version or python --version in your terminal and you see output of the form. Python 3.7.*, youʼre all set. Starter Code Download a copy of the starter code here. In your terminal, use cd to navigate to the cs168-sp25-proj3-transport/ext/cs168p2 directory. All of the Python commands should be run from this directory. To check that your setup works, in your terminal, run: python ../../pox.py config=tests/sanity_test.cfg If you see this message, everything should be set up correctly: [test] [00:00:02] All checks passed, test PASSED You should only edit ext/cs168p2/student_socket.py. There are comments clearly indicating the places where you should fill in code. Guidelines: Donʼt modify any other files. Donʼt add any new files. Donʼt add any imports. Donʼt edit any code outside the sections indicated by the comments. Donʼt add any hard-coded global variables. Adding helper methods is fine. In general, if we havenʼt told you to use something, you probably donʼt need it. Our goal is not to trick you! New Spec Note: This spec has been rewritten for Fall 2024 to be clearer and provide a few extra hints. It may contain bugs. If you would like to work off the previous version of the spec, you can find it here. Project Overview This project is split into 9 stages. In Project 3A, youʼll need to complete Stages 1–5. In Project 3B, youʼll need to complete Stages 6–9. Each stage has its own unit tests, provided to you locally. Your grade will be determined only by these unit tests (no hidden tests). To run a unit test, navigate to cs168-sp25-proj3-transport/ext/cs168p2, and run one of these commands, replacing 5 with the number of the stage you want to test: python autograder.py s5 # Runs unit tests for Stage 5. python autograder.py all # Runs all unit tests. python autograder.py all 5 # Runs all unit tests up to and including Stage 5. If a test fails, youʼll see some output like this: test_s1_t1 (__main__.test_s1_t1.test_s1_t1) ... Running test: ./tests/s1_t1.cfg Tracefile: ./trace/s1_t1/2024-08-22T16:09:52.593234 ../../pox.py config=./tests/s1_t1.cfg tcpip.pcap --node=r1 --no-tx --filename=./trace/s1_t1/20 FAIL To see nicely-formatted output for that specific test, take the last line, just before the “FAIL,” drop the --filename argument, and run that command in your terminal: ../../pox.py config=./tests/s1_t1.cfg tcpip.pcap --node=r1 --no-tx Code Overview You will be implementing the StudentUSocket class in student_socket.py, which represents a TCP socket. student_socket.py also contains other useful methods, which weʼll describe below. Modular Arithmetic Sequence numbers are 32 bits long, and they can wrap around (e.g. 0xFFFFFFFF + 1 = 0x00000000). Whenever you perform. arithmetic operations on sequence numbers, use these operators: State The instance variable self.state records the state of the current TCP connection. self.state is always assigned to one of the values in this list: [CLOSED, LISTEN, SYN_RECEIVED, ESTABLISHED, SYN_SENT, FIN_WAIT_1, FIN_WAIT_2, CLOSING, TIME_WA Weʼll describe more details about each state as they come up in the spec. Send Sequence Space: TXControlBlock The instance variable self.tx_data is a byte array representing what youʼre sending. The user will append bytes to the back of this array, and you will remove bytes from the front of this array as you send them out. The instance variable self.snd is a TXControlBlock object, which has information about the outgoing bytestream that you are sending. The TXControlBlock object has the following relevant instance variables: self.snd.iss: Your initial sequence number. self.snd.una: The oldest unacknowledged sequence number that you sent. self.snd.nxt: The next sequence number you should send. self.snd.wnd: The current size of your send window, determined by how much buffer space the other side (recipient) has left. This diagram shows the bytestream that you are sending and what the instance variables represent: Receive Sequence Space: RXControlBlock The instance variable self.rx_data is a byte array representing what youʼre receiving. As you receive packets, you should append their payloads (in the correct order) to this byte array so that the user can read them. The instance variable self.rcv is a RXControlBlock object, which has information about the incoming bytestream that you are receiving. The RXControlBlock object has the following relevant instance variables: self.rcv.nxt: The next sequence number you expect to receive. self.rcv.wnd: The current size of your receive window, determined by how much buffer space you have left. This diagram shows the bytestream that you are sending and what the instance variables represent: Receiving Incoming Segments The packets you send and receive are TCP/IP packets. If you receive an IP packet p, you can extract the TCP header and payload like this: seg = p.tcp If you receive a TCP segment seg, you can extract these fields from its header: seg.seq: The sequence number. seg.ack: The ack number. seg.win: The advertised window (how much buffer space left on the other side). seg.ACK: Whether this segment has the ACK flag set (Boolean value). seg.SYN: Whether this segment has the SYN flag set (Boolean value). seg.FIN: Whether this segment has the FIN flag set (Boolean value). If you receive a TCP segment seg, you can extract the payload like this: seg.payload # The payload. len(seg.payload) # Length of the payload. Sending Outgoing Segments To create a new packet, you can use the function self.new_packet(ack=True, data=None, syn=False), which takes in the following arguments: ack: Whether to set the ACK flag. True by default. data: The TCP payload to send. None by default. syn: Whether to set the SYN flag. False by default.

MLE5247 AY24/25 SEM 2 Assignment 2 You have two options to choose from. Please pick the one that interests you the most. Each earns a maximum of 35 marks. Option 1: Building and Implementing a Python Code Task: Use a neural network - such as a shallow MLP, a GNN, or even a GAN - to predict the band gap of a compound based on descriptors like composition or physical properties (e.g., density, formation energy). Steps to Consider: • You may use the materials dataset provided with this assignment. • Feel free to modify the dataset if needed (e.g., by adding features, including additional data, or selecting a subset). • You can use AI tools (e.g., ChatGPT, DeepSeek, Gemini, Co-pilot) to help generate, debug, or improve your code. However, please acknowledge their use, and remember that these tools can make mistakes or produce incomplete code. You’re responsible for verifying that each step aligns with your objectives. • Train/test your network on the band gap regression problem. • Visualize the distribution of predicted vs. actual band gaps, and discuss any limitations. Important Note: Our main goal here is not to produce perfect code or a fool proof band gap predictor. Your strength lies in your materials science expertise, so focus on applying your domain knowledge to design a model that’s appropriate for this task. Treat AI tools as a technical assistant that may not fully understand what you are trying to achieve. Comments in Your Code: • Include thought-process comments explaining why you chose certain parameters or models, any optimization considerations and other decisions, also shortcomings or how you might improve the approach further. Evaluation: • Your reasoning and logic will be the primary basis for evaluation, so ensure your ideas and insights are clearly expressed in your comments and discussion. o Logical reasoning (~ 20 marks) o Accuracy of code & implementation (~10 marks) o Output (~5 marks) Option 2: AlphaFold Background: AlphaFold - particularly AlphaFold2 from DeepMind - is a ground-breaking deep learning system that predicts a protein’s 3D structure from its amino acid sequence. It gained major recognition in 2020–2021 by outperforming all previous methods in the CASP (Critical Assessment of protein Structure Prediction) competition and was honoured with the 2024 Nobel Prize in Chemistry. Task: Conduct a literature survey to explore how AlphaFold actually works - both the ML- based and non-ML techniques that helped crack the longstanding protein folding challenge. Then, compile a report that: • Explains the problem of protein folding and the core challenges • Outlines how AlphaFold overcame these challenges • Breaks down the computation methods / process • Uses pictorials, graphs, or other visuals to clarify the mechanism You may use AI tools to aid your research, but do not copy text directly from them and acknowledge their use. Remember, AI outputs can sometimes be inaccurate, so please double-check any information you include. Evaluation: • There’s no fixed page limit, but as a rough guideline, 3 - 4 pages should be sufficient if you effectively capture and condense the model’s complexity (which will be challenging!). However, evaluation will focus on the depth of your insight into the inner workings of the model(s) and your ability to explain or illustrate them in a meaningful, clear way. o Background (~5 marks) o Motivations for and behind computational approaches (~5 – 10 marks) o Insight into AlphaFold (~25 – 20 marks)

EEEE2044 Coursework 2, Digital Modulation Report format Task 1: Change the parameter “Stop time” until you see that convergence of the BER value is achieved. Do this for at least 3 digital modulation techniques, namely QPSK, 16PSK and 16QAM. Once you have shown convergence you will need to use the appropriate value for the “stop Time” for the rest of the coursework. In Fig.1 plot the BER w.r.t. stop time for QPSK, 16PSK, 16QAM and comment on the results. Fig.1. Convergence of BER results for QPSK, 16PSK and 16QAM modulations Comment: The random integer input of all modulations are set to be 4, and Eb/No for all are set to be 10dB, with 2 of the number of bits per simple for QPSK, 4 for both 16QAM and 16PSK. The convergence of BER results for three different types of modulations are as shown in Fig.1. The BER curve for QPSK converges rapidly, achieving stability at approximately 4000-5000 seconds. This quick convergence aligns with theoretical expectations, as QPSK’s low-order modulation reduces susceptibility to noise and inter-symbol interference, enabling faster error rate stabilization. The final BER value is 4000 seconds to stabilize, which reflects the higher sensitivity of 16PSK to phase noise and synchronization errors due to its 16 distinct phase states. The final BER plateaus at approximately 0.5, which is notably higher than QPSK, highlighting the trade-off between spectral efficiency and error resilience. The BER for 16QAM is small at initial, which can be described as stable at initial. This is because of the input data size that doesn’t match with modulation (16QAM and 16PSK). The module might deem all the bits are wrong, but the logic limits the BER of 16QAM to be 10-5. Overall, the stop time that allows modulations to achieve BER convergence is set to be 5000s in following tasks. Task 2: In Fig.2 plot the BER for QPSK, 16PSK, 16QAM, 64PSK, 64QAM and 256QAM . The graph for each modulation is obtained by changing Eb/N ratio in AWGN block and reading the value in display block. The BER axis should be on a log scale. Fig.2. Comparison of BER for QPSK, 16PSK, 16QAM, 64PSK, 64QAM and 256QAM Comment on the results: (are the results logical and expected from what you have learned and how do they compare with other results (theoretical or other sources). Comments not to exceed this page. Task 3. Compare your results from the Task 2 with theoretical values and discuss. For this task only consider QPSK, 16PSK, 16QAM, 64PSK, 64QAM and 256QAM Fig.3.

QUESTION 2: Time Value of Money (23 marks) Part (a) – Investing in a Franchise Jordan is considering purchasing a franchise license to open a restaurant. The total license fee is $250,000, and the franchise company offers two payment options. However, Jordan also wants to consider a third option: delaying the purchase and saving up the full amount over 3 years. Payment Options Available: Option 1: Immediate Payment Discount • Pay $250,000 upfront now. • Receive a 5% discount on the total license fee if the full amount is paid immediately. Option 2: Deferred Payment Plan • Pay the license fee in equal instalment amounts over 5 years. • The franchise company charges an interest rate of 8% per annum, compounded quarterly. • Payments are made at the beginning of each quarter. Option 3: Wait and Save • Wait for 3 years and invest the initial $250,000 in a business savings account that earns 4% interest per annum, compounded annually. • After 3 years, the franchise company expects to increase the license fee by 10% due to inflation and rising costs. This is an estimate and may vary based on market conditions. Required: i. Calculate the present value of the license fee that Jordan will pay upfront if he chooses the Immediate Payment Discount (Option 1). Show your workings and round your answer to two decimal places. (1 mark) ii. Calculate the total amount of the payments Jordan would make under the Deferred Payment Plan (Option 2). Show your workings and round your answer to two decimal places. (4 marks) iii. If Jordan chooses the Wait and Save option (Option 3), calculate how much money he would have in the savings account at the end of 3 years if he invests the $250,000 at 4% interest per annum, compounded annually. Then determine whether this amount will be enough to cover the increased franchise license fee, which is expected to rise by 10% after 3 years. Show your workings and round your answer to two decimal places. (3 marks) Part (b) Saving for a Holiday Emily has a dream of taking a luxury cruise in 15 years, which currently costs $50,000. To pay for this, she plans to invest $25,000 in a fixed deposit account offering an annual interest rate of 6% compounded annually. Based on projections, her investment will grow to approximately $59,915 by the end of 15 years. However, if there is inflation, the cruise price could also rise to $77,900 in 15 years time. Required: i. Is Emily s fixed deposit plan a good strategy for achieving her goal? Consider the effects of inflation, compounding interest, and opportunity cost. (2 marks, max 200 words) ii. Suggest one alternative savings or investment strategy she could consider to better align her savings with her goal. Explain the potential benefits and risks. (2 marks, max 200 words) iii. Conclude with your opinion on whether Emily should stick to her current plan or revise it, supported by your reasoning. (1 mark, max 100 words) Part (c) Retirement You are a financial advisor specializing in retirement finance issues. Sarah has come to you with some questions about her retirement plans. Sarah has just turned 40 years old. Required: i. Sarah has saved $60,000 and believes this amount is sufficient for retirement if she invests it until she turns 65, without adding any further savings. If Sarah invests this money in an account with an interest rate of 9% per annum that compounds annually, how much will her retirement savings be worth when she retires at 65? (Round to two decimal places). (3 marks) ii. Sarah realises that the amount from your answer in part (i) of this question is not enough for retirement. She asks if she starts making deposits of $4,000 at the end of each month into a new account with an interest rate of 12% per annum, compounded monthly, how many months will it take for these deposits to reach a value of $326,680? (consider this schedule of cash flows independently of part (i) of this question). (Round to two decimal places). (3 marks) iii. KiwiSaver is a retirement savings scheme set up by the New Zealand Government. Visit the website https://www.ird.govt.nz/kiwisaver/kiwisaver-individuals/kiwisaver-benefits and find the following information: a. The minimum percentage an employer must match to an employee's own contribution. (1 mark) b. The maximum annual government contribution and the minimum member contribution. (1 mark) c. Compare KiwiSaver to at least one other retirement savings option available in New Zealand (e.g., personal savings accounts, term deposits, or managed funds). Consider aspects such as contributions, risk, and long-term growth potential. Which option do you think is better for long-term retirement planning, and why? (2 marks, max 200 words)
BUSM183: Services Management Module description Welcome to one of the most evolving topics in marketing literature. The services sector, such as telecommunications, financial services, hospitality, transportation services, healthcare, and professional services, accounts for over three-quarters of GDP and employment in developed countries. In light of the growing importance of services in local and global economies, it becomes crucial to study and understand the functionality of service offerings. This module will explore the distinctive characteristics of services and explain how these characteristics affect the marketing approaches used by firms – including challenges involved in controlling service quality, managing customer experience, and synchronising demand and supply. Thereby, the module will examine the management of service processes; customer experience in service settings; and the management of complaint handling and service recovery. This module is quite theoretical, which is why throughout the module case studies and hands-on exercises will facilitate understanding and transferability of contents. Various examples will also be used to illustrate the applicability and use of these theoretical perspectives on real world marketing practice. The module will enable students to relate and apply theoretical insights to concrete marketing and communication strategy; improve students’ ability in analysing case studies, brainstorming, and communicating ideas; and prepare students for the possible pursuit of a career in marketing. There will be one assessment for this module: an individual essay of 2,000 words, worth 100% of your grade. More details about the assignment are given below and on QMplus. The assessment allows students to apply and develop concepts learned in class. Organisation and delivery of module Each full week there will be a) a lecture, which will be predominantly done live in person (student engagement is required), but may also include other learning activities (e.g. asynchronous activities), and b) live seminar sessions where we will have group exercises, and also where you can ask questions about the week’s material. The lecture will be no more than 2 hours (including break) and the seminars will be about an hour each week on average, leading to a maximum of 3 hours of total course time each week. As per QMUL regulations, the teaching sessions will begin 5 minutes after the scheduled start time, and end 5 minutes before the end time (to allow you time to get to your other classes). Please also note that there will be no lecture nor seminars the first (partial) week of classes as well as week 7 (which will feature asynchronous learning activities). In weeks 10, 11 and 12, seminars will be is dedicated to the individual services project discussions. You will be divided into smaller groups and assigned to a tutor which will deliver seminars in a seminar room or have the individual services project discussions online. Preparation for Lectures and Seminars In the lecture, the basic concepts and theories of the textbook will be introduced, in addition to material that goes beyond the textbook, which is relevant for the assessments of the module. Seminar exercises will take place during the seminars, which intend to ensure a comprehensive understanding of the topic area and to make sure that students are able to detect and transfer learned concepts to practice. To achieve this goal, a mixture of case studies, discussions, and hands-on exercises is used. Seminar exercises are the main forum where advice and assistance are provided. Preparation for lectures and seminars is a necessity. Information is given on QMplus regarding the readings and seminar tasks that you need to complete before attending the lecture, and additional seminar materials are posted on QMplus. It is the student’s responsibility to ensure that he/she has prepared adequately. All tasks aim to… − enhance your understanding of the topics covered in the lecture. − enhance your ability to bridge theory and practice. − help you to prepare for your dissertation. E-LEARNING: This course is supported by QMplus. Use QMplus for the following purposes: - Get all materials and additional reading lists related to this module. - Submit your assessments. - Communicate with each other. In addition to QMplus, online resources may be available for the textbook (e.g., cross puzzles, flashcards). By purchasing the textbook you should get access codes for these resources, if available. Aims and Learning outcomes This module will begin with an overview of the concept of services and challenges associated with the marketing and management of services. The aim of this module is to: 1. Identify and explain the unique characteristics of services that distinguish them from goods, and it seeks to characterize the differences between marketing in services vs. manufacturing firms. 2. Provide students with an in-depth understanding of key issues in the design, management and commercialisation of services. 3. Describe important services marketing frameworks and explain how to utilise them to develop and implement advanced strategies in service contexts. 4. Provide students with relevant analytical skills and tools for critical thinking about services, their design, management, and commercialisation. The School of Business and Management has developed new sets of programme specific learning outcomes to be applied from academic year 2021/22 as part of the ongoing work on Assurance of Learning (AoL) to evaluate the programmes delivered and improve student learning.

Dr. Stephan Dickert and Dr. Muhammad Riaz will provide a variety of individual responses, comments, advice and suggestions on your contributions in class (such as your own questions, answers to questions we have asked, contributions to discussion, your presentations in class etc.). The purpose of this feedback, which we will be giving orally, is to enable you to improve your learning, to help you to identify your strengths and weaknesses and to work on them. We call this “formative” feedback, and we regard it as a very important part of the teaching and learning process. Bear in mind, too, that you might also receive responses from your fellow students in class when they hear your presentations or your contributions to discussions – we call this ‘peer feedback’. Peer feedback is an important element of your learning as it often provides valuable comments on how clearly you express your arguments and how well you convey your evidence. If you see us during my office hours, we can provide some additional feedback on any aspect of your learning.

This does not include reference lists and bibliographies. The stated word count may be exceeded by a maximum of 10% (200 words). Marks could be deducted if you overshoot this limit. You may use AI (artificial intelligence) tools in a limited capacity when planning your essay. The specific AI policy for this module is presented herein as well as on QMplus. Individual Essay Structure An underlying assumption of the services marketing module is that students learn best and retain more when they actively apply and work with the concepts presented in the course materials rather than simply read about them or hear the talk about the ideas. The purpose of this assignment is for you to apply concepts and tools learned in class to real situations. This assignment is designed to help students develop the ability to make marketing decisions in the services context, to support these decisions with appropriate analyses, and to learn to communicate their ideas coherently. By completing the assignments, you will learn to apply the concepts and models in practice, to critically analyse them and to discuss implications. As a learning exercise in this module, you will design a new service or redesign an existing service. You are required to use the knowledge you developed on the key aspects of services marketing as discussed in the module. You are also expected to consolidate the range of skills that you possess to search for and analyse relevant information in order to evaluate different aspects of a service’s marketing strategy. In doing so, it will be necessary to use the relevant marketing theories as a platform. for the evaluation and to build on your critical thinking and creativity skills. There is no single ‘correct’ way to present the plan as it will vary according to the nature of the business in question. However, you could consider the following structure as your reference: Title of new or redesign service · Creating a brand name is preferable · Brand logo is preferable Introduction · Start with the business challenge in the market/industry that you aim to use your newly developed service to conquer/solve · Introduce the service organisation of your choice · Support your justification with facts and figures with relevant references (e.g.industry, company, news sources) is preferable Target market segment(s) & Position in the market: · Describe the market segment(s) that you want to target · How you want your service to be positioned relative to the competition What type relationship you want to have with your target customers, and how. · You should provide justification for why this service idea would be valued by your target and why your service will be able to serve the needs of this group better than competitors. Be sure that you sufficiently investigate competitors that exist. · Support your justification with facts and figures with relevant references (e.g. industry, company, news sources) is preferable · You could integrate this part with introduction if that could increase readability and enhance logic Proposed marketing mix: · Just focus on the most relevant Ps to your service · The key components of your service and all of your tactic decisions (the 7 Ps) should then be based on the above analysis of your market segment and positioning. · Service delivery process and service recovery strategies: – You should create a thorough service blueprint for your chosen organisationand make explanation of how it will work. If you are redesigning an existing service, you should also include a blueprint of the original service. You are required to relate and apply the service marketing principles such as service provision process, consumer experience, blueprinting, and service recovery. It is necessary that you should see yourself as a consultant that identifies problems involved in the consumer journey within a service sector and proposes alternatives that improve the consumer service experience. · Physical evidence/ Servicescape – What role does the servicescape play for this organisation’s services? How might the servicescape be used as a source of competitive advantage by the organisation? · People: – How to have suitable “people” in your service? How to create an effective and efficient working environment? · Promotion: – which communication media used to attract new consumers and retain loyal customers (e.g., touchpoints)? · Other marketing mixes relevant to your (re)designed services? Launch and implementation schedule · Just 1-2 sentences to show your plan · Aim of this part if to demonstrate the service is realistic and feasible · If you could use other source of information to justify your launch and implementation schedule, this is preferable Conclusion · Just 1-2 sentences to summarize your service · Discuss the implications of your services to service industry, local economy, targeted consumers, general public, etc. · Discuss the limitations of your services and suggestions/recommendations to the future services References: Whenever you incorporate information from any articles or comments published in online or offline publications, you need to provide citation and a list of all cited references. Use the Harvard (or APA) Referencing System - for a guide see http://libweb.anglia.ac.uk/referencing/harvard.htm or https://apastyle.apa.org/ Although primarily written for a business audience, your Service Design Project should nevertheless draw upon appropriate concepts/tools covered in the module, external data sources and your own further reading/research, all appropriately referenced.

EEEE2044 Coursework 2 Digital Modulation The aim of the coursework is to evaluate BER for a range of popular digital modulation techniques. The coursework has a total of four tasks: - Task 1 is familiarisation with the Matlab Simulink programme and the parameters of the simulation. For this part a manual on how to build a simple communication channel is added in this document. - Task 2 is evaluation of the BER for QPSK, 16PSK, 16QAM 64PSK, 64QAM, and 256QAM modulation techniques in the presence of the additive white Gaussian noise. For a given modulation scheme, the BER analysis is done by changing the signal to noise ratio (parameter Eb/No) in the communication block that has additive white noise (AWGH block). Please note that the simulation parameters will need to be adjusted for each modulation technique. - Task 3. In this part you will attempt to validate your results from Task 2. For this task, you need to find the theoretical values of the BER for selected modulation schemes and plot them for above modulation schemes. Discuss agreement or discrepancies with results obtained in Task 2. Note that Part 3 is an element of the coursework that is aimed at distinguishing students in the 70-100% mark band. - Task 4 will consider a practical transmission system where additive white noise, time delay and frequency offset are added as a consequence of a more realistic communication system. The effect of the low pass filter on signal spectrum is also included. In this task you will plot BER for QPSK and compare that results from the one obtained in Task 2 and comment on the results. Guidance on how to build a communication link in Simulink is given in the Appendix. A report of results should be in the provided document and should not be longer than 4 pages. The penalty for exceeding the length is 5% per page. The marking scheme is given in Table 1. Table 1. Rubric marking scheme

You can submit a hard copy of your summary to your tutor any time during the following week. It is best to choose a topic in Week 1. If you are unable to do so, you will be left with limited choice. Below are specific requirements and expectations: General tips for a good presentation · What really matters is not how much you say but what you say and how well you say it. · Read the assessment criteria before beginning to prepare your presentation. · It is up to you whether or not to use PPT and/or other visual aids. Please keep in mind that clarity, structure, organization and creativity are essential assessment criteria. · It is a good idea to limit your presentation to 7-8 minutes, so that you will have 2-3 minutes for class discussion and Q&A. · Your presentation must include a brief overview of the topic and in-depth analysis of one or no more three aspects of the topic. · Your presentation must argue a particular point of view about one aspect or no more three aspects of the tutorial topic. If you present on more than one aspect, the various aspects must be integrated. · Your thesis must be original, not drawn from the assigned readings. · Good style. is usually characterized by A (accuracy), B (brevity), C (clarity), F (finesse), and S (simplicity). Specific tips for a good presentation - A good presentation is well-structured and follows a clear and consistent organizing principle. - Do not present long summaries of historical events. You can assume that your tutor and classmates already know the events quite well. - Do not summarize any secondary readings. You must develop your own argument, and then support your argument by mentioning or citing the secondary readings as appropriate. - Do not comment on whether you think the writing is good or bad. Your presentation should instead be aimed at making an evidence-based argument about the primary writing/writings. - Do not read from a script, unless you absolutely have to. It is much better to use a simple page of notes or cues, and then speak naturally. As long as you speak clearly, your grammar is not important to your mark in this assessment.
Assessment 2 PS931 - Bayesian Approaches in Behavioural Science Spring Term 2025 (updated: 2025-02-12) • This assessment counts for 42% of your overall grade. • Submission Instructions: Please submit your solution as one pdf document to Tabula as “Assess-ment 2” by midday (12 noon), Wednesday, 9th April 2025. • Important: Your document should be called YOUR-STUDENT-ID_a2.pdf. Please also add your student ID to the top of the document. To help ensure anonymous marking, please refrain from including your name in the document (or the file name). Task There are many approaches to modelling the cognition and behaviour of humans and other animals, and decisions can be viewed at at range of levels, from the behavioural level (patterns of outcomes) to the neural level (detailed cognitive processes). Bearing this in mind, please supply an answer, in the form. of an essay, to the following question: To what extent can Bayesian models explain individual differences in decision-making? Criti cally assess this in relation to cognitive biases and heuristics, using illustrative examples from peer-reviewed studies. All references should be included at the end, in APA-style. format. The essay has a maximum length of 2000 words. The word count does not include the reference list (nor the title). Finally, please note that submitting AI-generated text for this assessment will be considered as plagiarism; i.e., suspected cases will be referred to the academic integrity panel.
GEOG5102 Applied GIS Python Programming Assignment Part A You are provided with three Excel files that contain grass growth rates (kg/DM/Hectare) measured at regular intervals between 10/01/2013 and 13/07/2015 at a dairy farm in Ireland. The three different excel files correspond to three different trials: High stocking rate, Medium stocking rate, and Low stocking rate. Stocking rates refers to the number of dairy cows a farmer would have out grazing on a given amount of land over a certain period of time and is generally expressed as the number of livestock units (LU) per unit of land area. In our case, Low = 2.51 LU/ha; Medium = 2.92 LU/ha; and High = 3.28 LU/ha. Stocking rate is important as 1t is the main driver of milk production in grazlng dairy systems due to its impact on milk production per hectare and on the amount of grass that is utilised (eaten) per hectare. You are required to produce a suitable figure that displays the temporal change in grass growth rate for the three treatments throughout the study period on a single plot using Python. You are also required to generate a figure which contains three subplots, one for each of the separate treatments. Deliverables for Part A are a Notebook file (.ipynb) and a pdf of the Notebook (i.e. the .ipynb saved as a pdf including the generated outputs and any associated markdown). Please name these files as follows: (where studentnumber should be replaced with your actual student number). studentnumber_PartA.ipynb studentnumber_PartA.pdf Part B During the practical sessions you gained some familiarity with scripting in Python and its integration with ArcGIS. You are required to develop a stand-alone script that will: - Clip a raster DEM to a defined shape - Create vector contour lines from the clipped raster DEM. You will clip the ArranDEM.tif that you have used in Practical 3 to the extent of the polygon shapefile arranF.shp. The contour interval should be 30 meters and the base contour should be 0. Running the script. should create two outputs: - A clipped raster DEM - An output shapefile of 30m contour lines for the Isle of Arran. Deliverable for Part B is the single python file that will perform. these functions when run. Please name this file as follows: studentnumber_PartB. Three files altogether (for Part A and Part B) should be submitted to Moodle as individual files, i.e. do not zip them together. You are responsible for ensuring that the submitted script files runs correctly and that comments are used throughout the script to describe what processes are being carried out. Please ensure all submitted scripts contain the following header: # and # student numbers # file was created> Don't forget that the ArcGIS Pro Help can be a useful resource if you need to figure out the syntax for a particular command. This assignment accounts for 40% of the credits for the Applied GIS course and Part A and Part B are weighted equally. Please submit these files to Moodle by 17:00 on Friday 28th March 2025
ENGY7000 – Energy Storage Tutorial Question 1 One of the stated advantages of electric vehicles is the possibility of Vehicle to Load (VtL) discharging, whereby the electric vehicle battery is discharged to power a household or components of a household. Consider the BYD Dolphin Essential which features a single 70kW/180Nm front-mounted electric motor, powered by a 44.9kWh Blade lithium iron phosphate (LFP) battery. It features a DC to AC converter to allow the EV to run appliances or devices. If a household were to lose power due an extreme weather event, how long (or for how many cycles) could the Dolphin keep the following appliances running? I used https://calculator.energyrating.gov.au/for the appliance data. a) LG 315L Top Mount Frost Free Silver Fridge GT-3S b) Westinghouse Washing Machine WWW9024M5SA c) Bosch GV642B_WT Dishwasher d) Daikin RZAV85C2V1/FCA85CVMA Split Cycle Air Conditioner to cool my home What are some additional challenges of operating your EV as a home battery (outside of extreme weather events)? Question 2 If a home battery has a discharge efficiency of 92% and a charging efficiency of 89% calculate the round trip efficiency for each cycle of the battery. Question 3 Consider your night-time appliance use in your own home. Using the energy ratings calculator above, calculate the daily energy required for your house to operate from 6pm to 6am across the summer months. Then: a) Estimate the size of battery required to keep your house ‘off-grid’ during the night. b) Estimate the size of the solar array needed (18% efficiency) to charge the battery during the day. Use the moduleSIM.xls file and your home location as the input data.
