Steel, ever-evolving material, has been the most preeminent of all materials since it can provide wide range of properties that can meet ever-changing requirements. In this course, we explore both fundamental and technical issues related to steels, including iron and steelmaking, microstructure and phase transformation, and their properties and applications.

This course covers chemicals in our environment and in our bodies and how they impact our health. It addresses policies and practices related to chemicals, particularly related to how they get into our bodies (exposures), what they do when they get there (toxicology), how we measure them (biomonitoring) and their impact on our health. Most examples are drawn from the US.

This course covers the most important numerical methods that an engineer should know. We derive basic algorithms in root finding, matrix algebra, integration and interpolation, ordinary and partial differential equations. We learn how to use MATLAB to solve numerical problems. Access to MATLAB online and the MATLAB grader is given to all students who enroll. We assume students are already familiar with the basics of matrix algebra, differential equations, and vector calculus. Students should have already studied a programming language, and be willing to learn MATLAB. The course contains 74 short lecture videos and MATLAB demonstrations. After each lecture or demonstration, there are problems to solve or programs to write. The course is organized into six weeks, and at the end of each week there is an assessed quiz and a longer programming project.

The fourth and final course of the Impacts of the Environment on Global Public Health specialization will cover two topics. The first is environmental justice – that is, avoiding an inequitable distribution of environmental health threats in our population, and ensuring a healthy and safe environment and health equity for all. The second is risk assessment and management, a framework that can be utilized to assess and quantify human health risks, and to identify appropriate approaches to mitigating those risks and promoting better health. We will explore the steps involved in risk assessment, as well as how risk assessment can incorporate and address environmental justice issues.

Digital Signal Processing is the branch of engineering that, in the space of just a few decades, has enabled unprecedented levels of interpersonal communication and of on-demand entertainment. By reworking the principles of electronics, telecommunication and computer science into a unifying paradigm, DSP is a the heart of the digital revolution that brought us CDs, DVDs, MP3 players, mobile phones and countless other devices. The goal, for students of this course, will be to learn the fundamentals of Digital Signal Processing from the ground up. Starting from the basic definition of a discrete-time signal, we will work our way through Fourier analysis, filter design, sampling, interpolation and quantization to build a DSP toolset complete enough to analyze a practical communication system in detail. Hands-on examples and demonstration will be routinely used to close the gap between theory and practice. To make the best of this class, it is recommended that you are proficient in basic calculus and linear algebra; several programming examples will be provided in the form of Python notebooks but you can use your favorite programming language to test the algorithms described in the course.

In this course, you will learn how the changing Arctic environment is tied to the growing economic and strategic importance of the North. After setting the stage through a review of the peoples of the Arctic and how they are dealing with change, Arctic governance, economies national defense, attention turns to marine use of the Arctic, oil and gas exploration, mining, fisheries and tourism. The course ends with a survey of recent Arctic events. Learning Objectives: Articulate the drivers of the growing economic and strategic importance of the Arctic in the context of the environmental changes unfolding in the region, governance, and geopolitics. Identify the impacts of the changing Arctic, both positive and negative, on the peoples of the North.

This is an introductory course for students with limited background in chemistry; basic concepts involved in chemical reactions, stoichiometry, the periodic table, periodic trends, nomenclature, and chemical problem solving will be emphasized with the goal of preparing students for further study in chemistry as needed for many science, health, and policy professions.

This course will expose you to the transformation taking place, throughout the world, in the way that products are being designed and manufactured. The transformation is happening through digital manufacturing and design (DM&D) – a shift from paper-based processes to digital processes in the manufacturing industry. By the end of this course, you’ll understand what DMD is and how it is impacting careers, practices and processes in companies both large and small. You will gain an understanding of and appreciation for the role that technology is playing in this transition. The technology we use every day – whether it is communicating with friends and family, purchasing products or streaming entertainment – can benefit design and manufacturing, making companies and workers more competitive, agile and productive. Discover how this new approach to making products makes companies more responsive, and employees more involved and engaged, as new career paths in advanced manufacturing evolve. Main concepts of this course will be delivered through lectures, readings, discussions and various videos. This is the first course in the Digital Manufacturing & Design Technology specialization that explores the many facets of manufacturing’s “Fourth Revolution,” aka Industry 4.0, and features a culminating project involving creation of a roadmap to achieve a self-established DMD-related professional goal.

This course provides a deeper exploration of mechanical assemblies and simulation, which are key engineering features of the design and manufacturing process. The foundation of engineering design is exploration and iteration. Design is rarely a perfectly linear and straightforward process. In this course, we'll explore mechanical assembly design and simulation, focusing on testing and improving design components and performance. As we move through design assumptions, testing, and refining design ideas, we'll come closer to a final design, while developing a deeper knowledge in Autodesk® Fusion 360™ for simulating and analyzing product functionality. After completing this course, you will be able to: • Describe the engineering design process and workflow in Fusion 360. • Summarize the trends that are influencing the design industry. • Demonstrate knowledge and skills in more advanced Fusion 360 CAD and simulation skills Looking for Autodesk Fusion 360 certification prep courses?

This course takes learners on a journey through a progression of systems-thinking and sustainability concepts. Using the beautiful game of soccer (also known as football in many parts of the world) as an analogy, we'll work together to illuminate real-world interdependencies (such as between climate change and human rights), building the chain of concepts in a fun, accessible way. Soccer/Football nerds and newbies alike will be entertained and, ultimately, rewarded with the epiphanies that come from seeing in systems more clearly. Those who complete the course will: create examples of systems parts, boundaries, and behaviors related to sustainability (and soccer/football); practice evaluating the sustainability of systems they care about using several complementary methods; generate ideas to improve the sustainability of a system they care about; and explain a mindset shift that would enhance the sustainability of a system they care about.
