Project #1 Guidelines General Information • Deadline: October 28, 11:59 pm • Work Independently: keep your do/Rmd files and your dataset private from other students. Copying and modifying another student’s code is plagiarism. • Length of the project: up to 5 pages of text, not including figures and tables • Your paper should be typed and spell-checked • Use ARIMA methods to forecast and analyze a time series of your choice o Minimum number of observations: 50 o Time series should be different from the ones used in lectures and problem sets. o The last observation should be recent and must be the most up-to-date observation available from the source. • Structure your project like a paper: o Start with a short introduction describing the data source and series you are analyzing, your motivation for choosing this series, and related literature (if relevant) o Describe the analysis you performed and the results o All the main results should be reported in tables (you cannot copy the STATA/R output – look up real papers to see how tables should look) o Write a conclusion summarizing your main findings o The quality of writing and formatting will matter for the grade Elements to include in your analysis • Plot the data; describe the patterns you see; decide whether transformation is needed. • If the data are seasonal, then it would be best to remove this component • Analyze it for stationarity • Fit several appropriate ARIMA models using the ACF, PACF, and information criteria to select an ARIMA model. • Present the parameter estimates for the best model. Do not give the estimates for the other models you tried. A table with information criteria for all fitted models is sufficient. • Investigate structural breaks • Construct a forecast (be specific about the date for which you make the forecast, and the method used for forecasting) and plot the data, together with the forecast and the 95% forecast intervals. Comment briefly on whether the forecasts seem reasonable.

VQB 5642 PERFORMANCE CODES METHODOLOGY AND STRUCTURE TOPIC 6: Case Study Assignment Notes The attached represents the form. which the final case study assignment will take. It will form the basis of a class discussion/workshop period. The paper purports to be a preliminary design report upon which a building surveyor has been asked to comment. In the assignment you are being asked to demonstrate that you can integrate the knowledge you have learned in individual subjects by putting together an analysis of a design report. The report is neither all good nor all bad. It may be technically weak in some areas and fine in others; it may have errors in interpretation of the BCA, or simply fail to explain adequately the reasoning behind the arguments advanced. You are being asked to assess it in line with the questions on the front sheet of the case study assignment. Tips for the Real Case Study Assignment Answering of the assignment starts with 15 minutes for reading time during which period no writing is allowed. Start by checking that you have the number of pages indicated on the front sheet of the assignment paper. Then take a note of the marking schedule. The time to do the assignment, following the reading time, is three hours long and the total marks will add up to 180. In other words, each question is valued at a minute a mark. So as a very rough guide spend 20 minutes on a question worth 20 marks. Try to attempt all questions, even if you run short of time. The first few words you write on a fresh question may be worth more marks than adding a few words to a question you have already substantially answered. In the case attached, the last question is worth a substantial mark. Remember that and leave enough time to tackle it. Then start to read the report. There is no need however, to read right through it before the 15 minutes is up or before you start to answer the questions. The assignment paper is structured so that you can read the report in sections and answer as you go. Remember Marks are for quality not quantity. You do not need to spend the whole of the assignment period writing. Thinking is a necessary part of answering each question well. This is an open book assignment. Bring any material with you that you feel comfortable with. Calculators are permitted- you may download BCA freely from ABCB website. GRADUATE CERTIFICATE IN PERFORMANCE BASED BUILDING AND FIRE CODES FINAL CASE STUDY ASSIGNMENT (MOCK) This paper must be surrendered after the completion of the assignment (open book).

What additional material would you expect to see in the final form. of a good Fire Engineering Report? 25 Submission for Comment to Building Surveyor Sunrise Building XYZ Architects 1. INTRODUCTION The report describes a proposal to use the performance clauses in the BCA to introduce more cost-effective alternatives into the design of the Sunrise Building by making use of fire engineering techniques. 2. REGULATORY FRAMEWORK The BCA 2019 Amendment 1 will be used to establish performance requirements for the building. In addition use will be made of the Australian Fire Engineering Guidelines (AFEG) 2021. Where the AFEG provides insufficient detail, use is made of codes and Guidance from elsewhere, as referenced in the report. The deemed-to-satisfy provisions of the BCA will be used here where there is no wish to depart from them. 3. BUILDING CHARACTERSTICS A sketch of the building in plan and elevation is given in Figure 1. The Sunrise Building is a 5- storey sprinklered office building of about 3000 m2 including one basement car park level with ancillary uses such as café, meeting rooms, storage and reception areas provided for in the design. The city site chosen is 64 m x 84 m bounded on two sides by existing buildings. The floor-to-floor heights are 4m at ground level, and 3m at the higher levels. An atrium passes through the building to bring natural light from roof level into the rear office spaces. The circulation at each level is via balconies alongside the atrium, which has the advantage of allowing flexibility of use of the tenant spaces, and access for occupants to the escape stairs without having to pass through adjoining tenancies. There is a café located at the ground floor of the building. For commercial reasons, the café is seen as being available for use by the public, who would enter the area by the terrace doors. The office spaces are conditioned with cooled or heated air. Some of the return air is allowed to trickle into the atrium causing partial conditioning of the space with air which would otherwise be wasted. There are automatically opening vents at the roof level which will control the flow of air through the atrium. The atrium is designed with a 3m high roof space constructed in glass and steel, with partial shading. The overall system will be energy efficient and is therefore desirable on environmental grounds. 4. OCCUPANT CHARACTERISTICS OF THE BUILDING The enclosed part of the café is 278 m2, which gives a population from the BCA of 278 people. In the atrium café seating area there would be a further 100 people and there are 1220 m2 of lettable offices which gives 120 people. If it is assumed that the café population exits via the terrace doors, the remaining population is 220 people. The BCA requires a total doorway width of at least 1.75 m for this population with the nearest door no more than 40 m from any point. These requirements are easily catered for by the wide main doors, and 2 × 800 mm doors to the service area at the rear. It is assumed that the occupants are alert and mobile at the time of the fire. 5. TRIAL DESIGN AND NON-COMPLIANCES A summary of the more important deemed-to-satisfy BCA requirements for fire safety are given in the Table for the building described above. roof2 hr2 hr2 0 toreyevery required stair1 person/10m 2at least1m wide, 2m clear height3mhydrantshose reelssprinklerstravel distance om astairatleast9mat least width ofstair,less25 requiredrequiredrequired throughoutrequiredfire extinguishersfire andsmokealarmssmoke controlcovering atriumfloorsmoke extraction from atriumroofrequiredrequiredrequiredrequiredtoachieveclearlayer3maboveopenexitroutes-100m/s in this casestair pressurisationrequired
ECON8022 - MACROECONOMIC THEORY Assignment 2-B - Fiscal Policy in OLG and NG Models 1 Problem 1: Multi-period OLG model with inelastic labor (OLG Model of Australian economy - OLGA) Consider a close economy lled with overlapping generations and a competitive rm. The model period is equivalent to 15 years. The household sector consists of 4 overlapping generations. Each time period a new house- hold is born and lives for four periods (J = 4). The size of newborn generation is normalized to 1. The household is endowed with 1 unit of time and age-speci c labor productivity (hj) each period. The household works full-time for 2 periods and retires in the last 2 periods. The household preferences are given by The household chooses a sequence of consumption and saving to maximize his discounted lifetime utility according to subjected to period by period budgets constraints where, j stands for agent's age at the calendar time t+j-1, cj,t+j-1 and sj,t+j-1 are consumption and saving at age j, and wt the market wage rate and rt is the market interest rate at the time t. Note that, the lifetime budget constraint has a form of The production sector consists of a representative rm that has the following production technology where Y output, A is total factor productivity, K is capital stock, and H is e ective labor (e.g., human capital). Capital depreciation rate is δ . The rm's opti- mization problem is given by where wt is the market wage rate and qt is the rental rate. a) Assume that h1 = 1, h2 = 1.5, β = 0.98, σ = 2, A = 1, α = 0.33 and δ = 0.05. Find the steady state solution numerically, using two computational methods: (i) Fsolve function and (ii) Gauss-Seidle algorithm. b) Calibration of the benchmark model: Adjust β to match the annual market interest rate of 4%. Report the life-cycle pro les of consumption and savings when r = 4%. c) Suppose the government appears and introduces a PAYG social security program that pays pension bene ts for retirees where Ψ is a replacement rate. We assume the government set Ψ = 30%. The household period by period budgets are given by The social security program is self- nanced so that where τss is a social security tax that adjusts endogenously to balance the social security program every period. Now assume the economy is in steady state. Find the steady state solution. Explain your results. d) Now, suppose that the government increases the pension payment for retirees to Ψ = 40%. Study the long run e ects of the pension reform on the economy (Steady state analysis). Explain your results. Solve for the transition paths. Remark 1 A simpple version of an OLG model was developed by Australian Treasury for scal policy analysis (OLG Model of Australian economy - OLGA) . 2 Problem 2: NGM model with fiscal policy (Treasury's Industry Model - TIM) We consider a NG model lled with a representative household, a representative firm and a government. In this model the government taxes private consumption, capital and labor income to nance an exogenous sequenes of lump-sum transfers. Time is discrete (t = 0, 1, ...). Preferences. The representative household lives in nitely and has the following preference: (1) where β is a time discount factor, ct is consumption and lt is leisure. A typical functional form is usually used in the literature with σ ≥ 0 and 0 < γ ≤ 1. Technology. There is a representative rm which has access to the following CRS technol- ogy: (2) where, At is the total factor productivity, kt is capital input and nt is labor input. The repre- sentative rm rents inputs in competitive markets. The law of motion for capital is kt+1 = (1 - δ)kt + it , where it is investment and capital depreciates at a constant rate δ . Government. The government collects tax revenue to nance a government spending program, Gt. There are two taxes: consumption tax (τc ), income tax (τI). The government budget constraint is given by (3) where qt is net rental rate, wt is market wage rate, qtkt is capital income and wtnt is labor income. In the model, we assume that the government spend all revenues on a public transfer program. Technically, the government gives Gt back to household in terms of lump-sum transfer, Tt = Gt. Household problem. The agent is given capital k0 initially and one unit of time in each period. The agent can invest in capital market. The labor supply is nt = 1 - l1 . The houshold lifetime budget constraint is where ct and it are consumption and investment; qt is net rental rate; and wt is wage rate; τt(c) and τt(I) are taxes on consumption, capital income and labor income, respectively. The household chooses a sequence of consumption, savings and labor supply to maximize its lifetime utility (1) subjected to the budget constraint (4). a) Solution method: Assume that β = 0.99, γ = 0.3, σ = 2, A = 1, α = 0.33, δ = 0.025, and τt(c) = 10% and τt(I) = 15%. Assume the economy is in steady state. Solve the model numerically and report the steady state solution. b) Calibration: Keep other parameter values unchanged and nd the value of β that is able to generate a capital-output ratio of Y/K = 3. c) Analysis 1: We can use the model to analyse the e ects of negative technology shock. Suppose that there is a permanent decrease in TFP to A = 0.95.Analyse the e ects on output, capital, consumption, employment and welfare in long run and during the transition. Explain your results. d) Analysis 2: We can use the model to analyse the personal income tax cuts to respond to the negative TFP shock in c). To do so we assume the government decreases the income tax rate to τI = 10% after the negative TFP shock. Analyse the e ects on output, capital, consumption, employment and welfare in long run and during the transition. To what extent the tax reform could mitigate the adverse e ects of the negative TFP shock. Remark 2 A simple version of this NG model was recently developed by Australian Treasury to study the effects of industry policy (Treasury's Industry Model - TIM) .

BAFI1042 Equity Investment and Portfolio Management Equity Portfolio Management Assignment Assessment Task 3: Equity Portfolio Management Assignment Marks: 40 marks Assignment Due Date: Friday of Week 14; 13 June 2025, 5:00 pm Melbourne time Word Limit: Maximum 3,500 words (excluding ToC, Appendix and References) Submission Instructions: The assignment will be submitted via Canvas, Turnitin Rubric/Marking Criteria: A marking rubric is provided on Canvas Format: Please submit your report in PDF format The assessment is submitted as an individual assignment You will be given funds to invest in the share market. You are required to construct two $1,000,000 equity investment portfolios: 1. A passive portfolio replicating the return and risk of the index 2. An active portfolio that has the aim of outperforming the index You will then prepare a report in which you can explain your investment strategy for constructing a passive and an active portfolio, and then evaluate the investment performance of each in terms of absolute and relative return, risk and attribution effects to explain the differences in performance of each portfolio. You will be given an equally weighted index of ten companies selected from companies listed on the Australian Stock Exchange. This assessment replicates the tasks that would be undertaken by portfolio managers in a real-world investment company. For the passive portfolio, your task will be to replicate, as closely as possible, the risk and return characteristics of the benchmark index. For your active portfolio, your task will be to select stocks and sectors that will aim to achieve a higher return than the index. Your task is not necessarily to produce a positive return. If the markets fall in value, then your passive portfolio should fall in value by a similar degree. Your active portfolio should aim to outperform the return on the index: if the index falls, your portfolio should fall by a lesser amount; if the index rises, then your portfolio should rise by a greater amount. Note that there is no requirement to outperform. the index for this assignment. The final submission should fulfil the following minimum requirements For Passive portfolio • calculate the number of shares required for your passive portfolio to replicate the composition of the index For Active portfolio Assess all ten companies and sectors from the index • analyse the outlook for each company’s industry • analyse the macroeconomic environment at the global and domestic level • identify the firms and sectors that you consider will outperform. relative to the index and build your active portfolio to reflect your predictions • analyse and comment on each company's financial ratios over the previous five years. The ratios used should demonstrate profitability, asset efficiency, and debt servicing capacity. The ratios should be relevant to each company and may not be the same for all your companies. Evaluate your findings and select six companies for your active portfolio • after assessing the ten companies, select six to be included in your active portfolio • describe the reasons for your selections (around 5 bullet points for each stock) • also, describe the reasons why you have not chosen the other four firms (around 5 bullet points for each stock) • assign portfolio weights for each of your companies and discuss why you have chosen the weights in comparison to the weight of each stock in the index • calculate the number of shares required for each company to create a portfolio with the initial weights you have selected for your active portfolio why are some companies overweight in your portfolio, and why are others underweight? what do these active weights mean for your portfolio’s potential performance relative to the index? Build your portfolios • create these two portfolios in LSEG Workspace, ensuring that all dates and numbers of shares are correct Portfolio Creation Dates Passive and Active • Start Date: Monday, 12 May 2025 Portfolio Names in Workspace • Passive: Student number Replication (e.g. s3254663 Replication) • Active: Student number Active (e.g. s3254663 Active) Benchmark Portfolio • BAFI 1042 Sem 1 2025 Portfolio Analysis period for both portfolios • Start Date: Monday, 12 May 2025 • End Date: Friday, 6 June 2025 Observe your portfolios’ performance over the analysis period • as the share prices change over the evaluation period, you will be able to watch how the returns on the index, your active portfolio and your passive portfolio react Report Summary should include the following minimum points • discuss your investment goals and stock selection strategies • what was the overall performance of the active portfolio, your passive portfolio and the benchmark index? For each portfolio • explain the investment objectives of each portfolio • show the portfolio creation in LSEG Workspace as of the creation date, demonstrating the correct security weights in each portfolio • explain the reasoning for your stock selection and weighting relative to the index and how this will contribute to the investment objectives • report your results for each portfolio relative to the benchmark portfolio • provide comments on the total return/risk and active return/risk of your portfolios • discuss the sectors’ and securities’ active weights in your portfolio • analyse the active return of both your portfolios with reference to the allocation and selection effects • provide a detailed attribution analysis of the returns on each portfolio with reference to the weight differences between the portfolio and the benchmark • describe any major market events that contributed to the return performance of the benchmark or your portfolios, if applicable • have you achieved (or not achieved) the goals for each of your passive and active portfolios? • You should embed screenshots of your portfolio analysis from relevant LSEG Workspace screens in the main body of your report for each section. Screenshots should be readable and clear • Screenshots alone are not sufficient for your analysis. You must find reasons for the results that have been achieved by analysing the effects of differences in security weights between your portfolio and the benchmark and discuss them clearly and in detail In your analysis, you should avoid making vague or overly simplistic comments that lack depth or detail. The discussion should go into the underlying reasons, implications, or mechanisms for portfolio performance relative to the return and risk of the benchmark portfolio. Your portfolio’s return differs from the benchmark due to the different weights assigned to each stock and sector compared to the benchmark. All your analysis should refer to these weight differences as they are the drivers of relative return and risk in your portfolio. Your final report should take the viewpoint of a portfolio manager explaining the portfolio return to an investor client. Your client will want a thorough explanation of the return and risk on their portfolio. Points will be awarded where the main assertions and conclusions are supported by relevant data and/or referencing, and there is evidence of thorough research. Finally, which of the two portfolios will you recommend for investment and why? Refer not only to portfolio return but also to risk and employ the relevant return-for-risk ratios that would support your conclusion for each portfolio. Data for your report from Workspace Workspace calculates the portfolio statistics and provides charts you will require for your report. The information you will need can be found in Workspace as listed below: Information Workspace Template and Tab Total and Active Return Equity Summary – Performance/Contribution Contribution to Return Equity Summary – Performance/Contribution Contribution to Portfolio Weight Equity Summary – Allocation Allocation and Selection Effects Brinson Single Currency – Attribution Details Contribution to Total Risk Ex-ante Multi-factor Risk – Portfolio Summary Contribution to Active Risk Ex-ante Multi-factor Risk – Active Summary Performance Ratios (Sharpe, Treynor, Tracking Error, Information Ratio) Returns Statistics – Overview Crop your screenshots to show only the section inside the red box.

ELEC0151: Simulation Design Coursework Brief 2025 Simulation Design 1: A fully differential biopotential amplifier design has been shown in [1] which is based on an earlier work [2]. A fully differential amplifier distinguishes itself from a single ended design, similar to the one shown in [3]. Assuming a single regulated power supply is available, your task is to evaluate and re-design the proposed design in [1] for a wearable solution through simulation and produce a document no longer than 3 pages that summarises your findings/design. In your evaluation, you should use different op-amps compared to those used in [1] justifying your choices. Your op-amp selection, beyond evaluating the information available in datasheets, can involve simulation studies. As part of the submission, you should propose two different op-amps for this design, demonstrating their viability. For every passive component also, you should clearly justify the values you have selected either through analysis, discussion or simulation. You should also redesign the circuit for a range of differential gain values (e.g., 200 to 2000 if viable), and at least for three gain values, to identify key limiting factors for this differential gain. One of the points you should consider is that input signals may have different DC offsets. You should evaluate what the permissible level of the differential DC offset is if that is found to be a limiting factor. The frequency of the target differential signal does not exceed 2 kHz. Bonus tasks: You should investigate if selecting resistors from different ranges have an impact where only the ratios are theoretically important. You should also investigate the impact of variations in the values of passive components in general. These variations can include both tolerance variations (e.g., 1% or10% resistor tolerances) or sweeping values in a wider range where relevant to evaluate the variation in, for example, time constants or break frequencies. Throughout, you should decide what set of simulation setup and results can best evaluate a given aspect of the circuit under investigation. Part of your results can include replicating the results in [1] where relevant. For example, CMRR analysis is among the most important investigations you should conduct for this application.

Simulation Design 2: Howland current pump (HCP) can be used when precise bidirectional or AC current should be passed through a load. The “basic” HCP as referred to in [1] is the originally proposed design. Due to a number of shortcomings of the basic design, the “improved” HCP is now the standard approach for most applications [1], [2]. Various other improvements have been suggested to the standard approach in the literature [2], [3], [4]. Assuming you have access to regulated power supplies of your choosing and signal generators with controllable attributes, you should first evaluate the basic HCP and demonstrate its shortcomings where possible using appropriate simulation setups. You can carry out this investigation using an op-amp of your choosing, justifying your choice. You should then design a current source based on the improved HCP. You should create a design capable of supplying currents from 0.5 mA to several tens of mA to loads ranging from 500 Ω to several kΩ over a range of frequencies up to about several MHz. You can apply any necessary adjustments needed to the improved HCP, as suggested in the literature, to accommodate the design specifications and to consider any other practical considerations including the cost and stability. You should present sufficient evidence to justify your choice of the op-amp(s). You should, overall, propose two suitable op-amps and demonstrate their viability in each case. Bonus tasks: Investigate the impact of resistor tolerances in your design. Also investigate the performance of your design where the resistive load also has a capacitive load in parallel with it. You should summarise your investigations and design in a document no longer than 3 pages. Include all evaluations and the necessary results that demonstrate you have fully or partially met the design specifications. One important metric is the current accuracy which should be included. If you do not fully meet the design criteria, you should appropriately discuss the outcome. References [1] Texas Instruments "An-1515 a comprehensive study of the Howland current pump."

Some examples include: LTSPICE,TINA-TI, or Multisim. Submission and marking guidelines: Please submit one .pdf file including entries for both Simulation Design tasks (maximum of 3 pages for each entry). The list of references for both entries should be included in one page at the end which does not count towards the page limit. You can also have a cover page for your submission if needed which will not count towards this page limit either. Marking guidelines: Organisation, methods and simulation setup (8/20) For each entry, your submission should start by a paragraph summarising your understanding of the circuit under investigation in which you should also highlight the key findings of your study. You should clearly but briefly describe your design approach. For example, if relevant, you should explain the specific designs/adjustments you have made from different options available, how you have selected components considering the range of available options and demonstrate any calculations/analysis you have done. You should also show the simulation setup, and indicate briefly how you have used the setup to perform the different studies you have conducted. Where multiple steps are involved, organise these steps in sections to improve readability. Results and discussions (8/20) It is very important that you present your results in a way that they are easily understandable and you should think carefully what the best set of results are to present. Mark is allocated to both presentation of results as well as the outcome (i.e., whether you have met the design and evaluation brief). You should clearly but briefly describe your results and more importantly discuss them, highlighting implications and causes of specific observations. Very importantly, where you cannot meet the design specifications, discuss clearly why you think that is the case. Appropriate use of external sources and referencing (4/20) Please use IEEE referencing style when you use external sources. Only use authoritative sources and ensure your design decisions are sufficiently supported by the existing literature. Always compare your finding with what you find in the associated literature. By appropriate use of references, you can avoid repeating description of methods and refer the reader to appropriate resources. This way, you can use the space available to you more efficiently. The 3-page limit per entry is not a target. For example, if you can convey all the necessary information in two pages, you should do that.

Photo: Eric Sutherland. https://walkerart.org/magazine/archives-marcel-duchamp Week 12 Steps Towards Your Final Project: Brainstorming/ Experimentation to Generate Ideas Over the previous 11 weeks of the semester, you have explored a range of approaches to creative practice within CAVA1001 and engaged in giving and receiving feedback. This has primed you for the next and last stage in the unit: the Final Work Project. To explore future creative directions in Week 12 you will undertake a series of brainstorming exercises. Materials to bring to class: Note pad Drawing paper Pen or pencil Tape Glue stick Aim: To discover an idea or theme that you can carry forward as the conceptual focus of your Final Work Project. It is important to enliven the idea through further brainstorming and studio-based experimentation. This is called practice-based research. The exercises you will undertake in class are just examples of generating ideas—you do not necessarily have to use these methods; however, you might find one to be exciting and helpful for your final project. Exercise 1 : The ‘Cut Up’ Method This exercise is all about embracing random associations and including an element of chance in your creative process. William S. Burroughs: Writer Figure 2.

Man Ray, Tristan Tzara, 1921, Paris, Centre Pompidou, © Man Ray Trust/ Adagp, Paris. To begin, we will quickly go around the class and everyone will contribute one word— any word that comes to mind. Everyone will write all words down in a notebook or on a piece of paper. Using the words write three separate phrases which use between 2 and 4 words. Play with the sequence of the phrases as a catalyst for new possibilities. Tips: Arrange your phrases randomly. Re-arrange them into new combinations. Use these words to spark ideas—let them trigger a brainstorm. Keep experimenting until you find a combination that sparks a strong idea. Document this phrase in your visual diary. Briefly explain how you plan to turn this idea into an artwork. Remember: your word/phrase list should be unique to you. Let the process guide your thinking—it will help you develop something more personal and original. Be playful and open—this can be a warm-up or the basis for your final work. Exercise 2: ‘Cut-Up’ Method to Image Figure 5. Richard Hartog/ Los Angeles Times via Getty Images, Artist John Baldessari in his Santa Monica studio, 2001. https://www.artsy.net/article/artsy-editorial-john-baldessari-artist-brought-comic-edge-conceptual-art-died-88 “ ... just as the work approaches the brink of absurdity, a prevailing order always reins it back in.” “A systematic Bewildering, Gardner,” Colin. Artforum International; New York Vol. 28, Iss. 4, (Dec 1, 1989): 106-112. “I think of humor as going for laughs and that’s not my purpose. I see my work as issuing forth from a view of the world that’s slightly askew.” John Baldessari, quoted in Hunter Drohojowska, “I Will Not Make Any More Boring Art: A Profile of John Baldessari,” LA Weekly 6 no. 33, 13-19 July 1984, 8. Generate a visual interpretation of your idea or theme which has come from the first ‘Cut-Up’ method in Exercise 1. On drawing paper or in a notebook make three separate line drawings inspired by your words or phrases. These are not detailed drawing—they are quick sketches to work through ideas, to find an image which comes from your idea. Tips: Start drawing by representing a visual element of your idea. Use your 'Cut-Up' research for inspiration if you like. Let the drawings evolve Ñfollow where it leads, rather than sticking too closely to the original idea. You can try to move away from words, shifting your thinking to a purely visual language if you want, or keep words as part of your composition. Use drawing freely—it's flexible and spontaneous. Be playful and relaxed—don't worry about perfection or outcome. Look back at all three drawings—is there something visually interesting to develop further? Decide how to use this—as a warm-up or as a foundation for your final project. Exercise 3: Self-Directed The previous exercises are structured to encourage you to play with ideas in a dynamic context and to engage in practice-based research. That is, to attempt to discover more about an idea or a creative direction through brainstorming and studio-based processes. As outlined, these exercises can be approached as open conceptual development activities, or you can try to find something specific to develop further as a theme for your response to the Final Work Project. Exercise 3: CAVA1001 Modules + Your Ideas = Self Directed On a sheet of paper or in a notebook write down a list on the left-hand side of all the Modules you have completed in CAVA1001 this semester—revisit each module in Canvas to refresh your memory if you like: Automatic Drawing Experimental Field Recordings Collage Painting Print Lab 3-D Object Studio Ceramic Lab Now, down the right-hand side write at least 6 words or phrases which come directly from you—distinct ideas or characteristics that make you who you are. These words could be about: Your cultural identity and heritage Interests and hobbies Social or political concerns Things that give you joy or entertainment Emotions: Happiness, kindness, humour or things that upset you Food, exercise, mental well being Happiness, kindness, humour Now link these words or phrases to one of the ways of working you’ve learnt about throughout the modules this semester. Think about which modules you enjoyed most, and which materials would suit your words, phrases and ideas best. What are you most skilled at? What way of working do you think has the most potential as a vehicle to articulate your ideas? Are you still lost for ideas? Here are some samples from a wry handout that John Baldessari gave to his students to: - Challenge the creative mind - Offer a teaching method which allows students to seek out ways of shaping work from their own internal logic. Variations on: CalArts Post-Studio Art: Class Assignments (Optional) - How can plants be used in art? - Give a verbal description of someone or something to another student to draw. - Collaborative digital collage project—each student gathers images & then swaps images with another to edit & make a composition. - What art could you make with a budget of $0? What themes might reoccur? How can you transfer these materials into art? How can you imbue these materials with meaning? - Make a storyboard with images of all the objects you look at in a random space or environment over a set interval of time. - Take the trash from someone’s wastepaper basket and make a collage portrait of them with the materials. - In a pairing of two students, one person makes up random captions. The other person gathers random images or take photos. Both match captions to images together. - Disguise an object to look like another object. - Make up a list by looking at art books and talking to artists about things to avoid when making art. Do them. Ask yourself if the results are good or bad. - What art can you make with a pair of Walkie Talkie radios? Or other electronic devices? - Can you make figurative sculptures using tissues and tape? - Photograph or draw the reverse of or underneath things—uncharacteristic views. - Put labels on things to list their contents. - Verbally describe a landscape instead of painting one. - Repaired or patched art. Recycle—find something broken and discarded & mend it with unconventional materials. What will you do for your Final Work Project? Working out the answer to this question is now the task at hand. Step 1: Reflect on your experimentation in Exercises 1-3 and try to select 1 idea that you can take forward as a possible response to the final project. This is your unique theme! Step 2: Develop a studio-based experiment for your theme that will assist you in understanding the idea even more. It is good to explore a range of possibilities and seek to discover new opportunities. Be creative, playful, experimental, inventive and innovative. Step 3: Present your experiment in class for discussion. And then engage in further creative development. These activities will be the focus of the Week 13 Class where there will be opportunity for discussion and critical feedback on your idea and work-in- progress. Left: Photogram by Man Ray.

Scenario In the highly competitive movie streaming services market, your client has asked for help with enriching their data with publicly available from the Internet Movie Database (IMDb), one of the most popular websites that contains large amounts of data on movies. You'll need data. Using a dataset from your client containing different data about movies, you are tasked with scraping online publicly available data to transform. the scraped data into a structured format and integrate it with your client's data to come up with an enriched dataset. Key Tasks This project has two parts with multiple tasks and separate deliverables for each part. Read each set of instructions carefully. PART A: Data Gathering, Transformation, and Enrichment. Download and unzip the needed file to work on Project 03.zip The project zip file includes three files: Project_3_Part_A.ipynb TopVoted_500_Movies_HTML.txt Movies.csv Perform. data gathering using web scraping to enrich your client's dataset (Movies.csv) containing top voted 500 movies released between 2018 and 2020. The dataset includes the following fields: movie_id: alphanumeric unique identifier of the title. originalTitle: original title, in the original language. description: a short description of the movie. ratingCategory: movie rating for empowering families to make informed movie choices. genres: includes up to three genres associated with the title. Rename Project_3_Part_A.ipynb Jupyter Notebook by adding your Group# or Lastname to the filename. Edit the code in the notebook to complete the following tasks: 1. Conduct Data Gathering: Scrape this IMDb webpage of movies released between 2018 and 2020, sorted by votes in descending order. Pull movie_id, rank, title, year, rating, and votes for the top 500 movies sorted by user number of votes in descending order. Transform. the scraped data to a structured format and write it to a CSV file (name it IMDb_TopVoted.csv). 2. Conduct Data Enrichment: Import the Movies.csv file to a pandas DataFrame. called df1. Import the scraped data from the IMDb_TopVoted.csv file to a pandas DataFrame. called df2. Implement data cleansing and transformation for the df2. Enrich the given dataset (df1) by merging it with the scraped data (df2). Rearrange the dataset fields to be listed in the following order: o movie_id, rank, title, originalTitle, description, year, votes, rating, runtimeMinutes, ratingCategory, genres Export the enriched dataset to a CSV file: o Use the following naming convention: Project_3_Part_A_Group#.csv PART B: Automate Data Transformation and Integration. Use Alteryx to automate the process that you applied in Part A to clean, transform, and integrate the data. 1. Create Alteryx workflow to: a. Import IMDb_TopVoted.csv dataset you created in Part A. b. Do the necessary data cleansing and transformation. c. Import Movies.csv dataset. d. Merge the two datasets to obtain the enriched dataset. e. Sort the enriched dataset by rank in ascending order, and rearrange the dataset fields to be listed as the following: movie_id, rank, title, originalTitle, description, year, votes, rating, runtimeMinutes, ratingCategory, genres a. Split genres into genre01, genre02, and genre03. Drop the original genres column after the splitting. b. Export the enriched dataset to CSV file: Use the following naming convention: Project_3_Part_B_Group#.csv 2.

BAFI1042 Assessment Task 3: Equity Portfolio Management Report Overview You are to construct two equity investment portfolios-a passive replication portfolio and an actively managed portfolio- by selecting stocks from an index of ten companies selected by the lecturer, which are listed on the Australian Stock Exchange. You will then prepare a report in which you are to explain your investment strategy for both portfolios and then evaluate the investment performance of each in terms of absolute and relative return, risk and attribution effects to explain the differences in the performance of each portfolio. Assessment Details You will be given funds to invest in the share market. You are required to construct two $1,000,000 equity investment portfolios: 1. A passive portfolio replicating the return of the index 2. An active portfolio to achieve your investment objective of outperforming the index You will then prepare a report in which you can explain your investment strategy for constructing a passive and an active portfolio and then evaluate the investment performance of each in terms of absolute and relative return, risk and attribution effects to explain the differences in performance of each portfolio. You will be given an equally weighted index of ten companies selected from companies listed on the Australian Stock Exchange. This assessment replicates the tasks that would be undertaken by portfolio managers in a real-world investment company. For the passive portfolio, your task will be to replicate, as closely as possible, the risk and return characteristics of the benchmark index. Your task is not necessarily to produce a positive return. If the markets fall in value, then your passive portfolio should fall in value by a similar degree. Your active portfolio should aim to outperform. the return on the index: if the index falls, your portfolio should fall by a lesser amount; if the index rises, then your portfolio should rise by a higher amount. Learning Outcomes The targeted Course Learning Outcomes for this assessment are: CLO1: Examine the general investment framework and assess the importance of asset allocation as an investment strategy CLO2: Illustrate the concept and application of modern portfolio theory, capital market theory and examine their relation to multifactor asset pricing models CLO3: Review the difference between fundamental and technical analysis while making an investment decision CLO4: Evaluate the performance of a listed company by investigating the impact of various economic indicators and applying security valuation techniques CLO5: Create and analyse active and passive portfolios by examining the role of risk and return in the investment decision process CLO6: Compare and contrast different performance evaluation techniques to assess the performance of a portfolio manage
