    I am a senior Chemical Engineering student here at the University of Alberta. My degree has given me a strong experience in process design, separations, reactor analysis, and safety. Through my work in operations and engineering support at oilsands and gas plants, I gained hands-on exposure to piping systems, instrumentation and real world problem solving. I am interested in process and facility engineering positions where I can work on optimization and solving real problems. I enjoy being an engineer with getting tangible results and working with different teams. I am less interested in purely theoretical or research heavy roles that are disconnected from practical industrial application.

  • Weekly assignment 2

    Reminder of how it works:

    1. Readings and Videos: Each week, you will have assigned readings and videos in the course modules’ Read and Watch sections. These resources will provide you with essential knowledge and insights on the topics at hand.
    2. Weekly Activity: After completing these readings and videos, it’s time for the “Weekly Activity”. This activity will challenge you to put your learning into action, applying the newly acquired knowledge to practical scenarios. These activities are crucial, as they will form the building blocks for your . The business idea, product, market, etc. from your weekly activities should be the same as those in your term project.
    3. Research-Based Submissions: For maximum benefit, approach the weekly activities with dedication and a research-oriented mindset. Aim to provide comprehensive, well-researched submissions that showcase your understanding and creativity. Utilize external sources, articles, and real-life examples to bolster your answers.
    4. Leverage Your Work: Here’s the exciting part all the content you create for the weekly activities can be utilized and updated for your term project! By investing time and effort into each weekly assignment, you’ll have a significant advantage when it comes to efficiently completing the later in the semester. Think of the weekly activities as a solid first draft of the component of your term project.
    5. Watch the Introductory Video: Before attempting each weekly activity, make sure to watch the corresponding video providing an introduction and discussion of the task at hand. The video will contain valuable insights, tips, and guidelines that will help you approach the questions with clarity and confidence.
    6. Resist Skipping Ahead: We know it’s tempting to skip to the end of the introductory video to see the questions, but trust us watching the entire video and taking notes will benefit you tremendously. It ensures you understand the right approach to the questions and identifies the resources you need to answer them effectively.
    7. Stay Enthusiastic and Encouraged: Embrace the challenges of each weekly activity with enthusiasm and a positive mindset. Remember, every step you take brings you closer to mastering the subject and excelling in your term project.

    You should do the software research, results & discussion

    A desired length would be approximately 4,0005,000 words, specifically for the Results and Discussion sections.

    I am sending you my thesis again in its final form, as I currently have it, so that we can communicate more effectively.

    We are now moving to the implementation stage of the methodology. I have already written the methodology section, and now we would like to run simulations using the software tools SAM and OpenModelica in order to produce results (WE ARE CREATING A CHAPTER ENTITLED RESULTS & DISCUSSION) and analyse the outputs produced by these tools.

    From this point onward, the goal is:

    • Execution of the modelling:
    • SAM simulation
    • OpenModelica dynamic simulation
    • (if time permits) Python sensitivity/stochastic analysis
    • To write a Results chapter immediately
    • (including graphs/tables showing the simulation outputs).
    • Then, to write a Discussion chapter
    • where the results will be discussed in relation to the objectives I have already set in Chapter 1.

    Therefore, I need modelling in the software tools and modelling results.

    The input data for the software will include information such as:

    Project Setup

    Technology:

    • Photovoltaic (Detailed)

    Financial Model:

    • Generic System

    Location

    • City: Athens, Greece
    • Weather Data: PVGIS TMY

    Expected annual irradiation:

    • 17001800 kWh/m2
  • Ethics and professional practice in engineering

    I have to write a 3500 word essay about ethics and professional practice in engineering in english s a second year architecture student, i have to use harvard style referencing and have intext citations from reliable sources only, such as research gate. Th report must demonstrate understanding of key principles, application to engineering practice, such as case studies of successful projects and failed projects in context to good and bad ethics, it must include a critical analysis (not description only) snd use relevant academic and professional sources, and 0% ai. Also have a table of contents page to outline the structure.

  • Towers

    Background

    You are the Project Manager for Apex Construction, a General Contractor (GC) that has just been awarded a $45 million contract for a 12-story mixed-use development called “Riverwalk Towers.” You are currently in the buyout phase, finalizing subcontracts.

    The Situation: For the Structural Steel package, the estimating team received three subcontractor bids, and, as estimators do, they used the smaller of the three numbers at the time of the bid to the owner.

    1. Vendor A: $5,200,000
    2. Vendor B: $4,950,000
    3. Mid-State Steel (Vendor C): $1,250,000

    The Issue

    Mid-State Steel is a reliable, family-owned subcontractor youve worked with before. Their bid is nearly $3.7 million lower than the nearest competitor. Upon a quick internal review of their line items, your Estimator realizes Mid-State likely forgot to include the cost of the raw steel materials and only quoted the labor and fabrication.

    If you hold them to this price, your project profit increases by nearly 8%, making you a hero to your executives. However, a $3.7 million loss would likely bankrupt Mid-State Steel halfway through the project.

    Assignment

    Write a 3-page, double spaced paper, with 12pt font responding to the items below. CITE YOUR SOURCES.

    Legal & Contractual Obligation: Does a “meeting of the minds” exist? Research the legal implications of enforcing a contract when the GC knows (or should have known) a clerical error was made.

    Operational Risk Assessment: What happens to the project schedule and quality if the subcontractor goes belly-up during the erection of the 4th floor?

    Professional Ethics: How does “bid shopping” or exploiting a mistake impact your reputation in the local subcontracting market? Is there a “middle ground” solution (e.g., allowing a corrected bid or a re-scope)?

    AI Policy: Assisted Drafting & Research

    In the construction industry, AI is increasingly used to summarize documents and flag risks. For this assignment, you may use Generative AI (e.g., ChatGPT, Claude) as a research and drafting assistant, but not as a replacement for your own analysis. Your assignment will be checked for the use of AI.

    • What is allowed: Using AI to brainstorm “middle ground” solutions, summarize legal definitions (like “scriveners error”), or check your paper’s grammar and flow.
    • What is prohibited: Submitting a paper that is primarily AI-generated. The “Operational Risk Assessment” and “Professional Ethics” sections must reflect your personal judgment as a future Project Manager.
    • Disclosure Required: If you use AI for more than basic proofreading, you must include a brief “AI Disclosure Statement” at the end of your paper (e.g., “I used ChatGPT to help structure my outline and research the legal definition of meeting of the minds.”).
    • Accountability: You are 100% responsible for the accuracy of your paper. If the AI “hallucinates” a legal case or a construction cost that doesn’t exist, you will be graded accordingly.
  • NO AI WRITING

    Description of task(s) to be completed: You are required to write a piece of individual coursework addressing the task below.

    Human systems engineering (HSE) seeks to ensure we address human considerations within systems engineering (SE) across the whole life cycle.

  • Figure 1. Human Factors Activities Across the Systems Engineering Life Cycle (adapted from module material).

    Where to place it:

    Place it in Part 1, after you introduce HF across the life cycle.

    Then explicitly refer to it in the text, for example:

    As shown in Figure 1, human factors activities span requirements definition, architectural allocation, verification and in-service monitoring, rather than being confined to detailed design.

    Then in Part 3, refer back to it when discussing autonomy:

    With increasing automation, task allocation and verification activities shown in Figure 1 become more complex, requiring explicit modelling of humanautomation interaction.
