Electric powertrains are estimated to propel a large part of road vehicles in the future, due to their high efficiency and zero tailpipe emissions. But, the cost and weight of batteries and the time to charge them are arguments for the conventional powertrain in many vehicles. This makes it important for engineers working with vehicles to understand how both these powertrains work, and how to determine their performance and energy consumption for different type of vehicles and different ways of driving vehicles. This course is aimed at learners with a bachelor's degree or engineers in the automotive industry who need to develop their knowledge about electric powertrains. In this course, you will learn how electric and conventional combustion engine powertrains are built and how they work. You will learn methods to calculate their performance and energy consumption and how to simulate them in different driving cycles. You will also learn about the basic function, the main limits and the losses of: Combustion engines, Transmissions Electric machines, Power electronics Batteries. This knowledge will also be a base for understanding and analysing different types of hybrid vehicles, discussed in the course, Hybrid Vehicles. As a result of support from MathWorks, students will be granted access to MATLAB/Simulink for the duration of the course.

Too often modern cities and suburbs are disorganized places where most new development makes daily life less pleasant, creates more traffic congestion, and contributes to climate change. This trend has to change; and our course is going to show you how. Ecodesign means integrating planning, urban design and the conservation of natural systems to produce a sustainable built and natural environment. Ecodesign can be implemented through normal business practices and the kinds of capital programs and regulations already in use in most communities. We will show you how ecodesign has already been used for exceptional projects in many cities and suburbs—from Hammarby Sjöstad in Stockholm to False Creek North in Vancouver to Battery Park City in Manhattan, as well as many smaller-scale examples that can be adopted in any community. Cities and suburbs built according to ecodesign principles can and should become normal, instead of just a few special examples, transforming urban development into desirable, lower-carbon, compact and walkable communities and business centers. As this course describes specific solutions to the vexing urban challenges we all face, course participants can see how these ideas might be applied in their own area. Participants will learn the conceptual framework of ecodesign, see many real, successful examples, and come to understand the tools, processes, and techniques for policy development and implementation. Ecodesign thinking is relevant to anyone who has a part in shaping or influencing the future of cities and suburbs – citizens, students, designers, public officials, and politicians. At the conclusion of the course participants will have the tools and strategies necessary to advocate policies and projects for a neighbourhood or urban district using the ecodesign framework.

Cities are built site by site. Site planning has been taught in urban planning, landscape architecture and architecture programs for over a century and continues to be a foundation course for those who aspire to plan the built environment. It is a required subject on licensing and certification programs for each of these disciplines. Mastering the art of site planning requires substantive knowledge, well-honed design skills, and familiarity with examples and prototypes of site organization. This course provides the perspectives of leading academics and practitioners on the important issues in preparing site plans. It offers a foundation of knowledge, and the opportunity to apply what is learned in preparing a site plan.

Humanity faces an immense challenge: providing abundant energy to everyone without wrecking the planet. If we want a high-energy future while protecting the natural world for our children, we must consider the environmental consequences of energy production and use. But money matters too: energy solutions that ignore economic costs are not realistic, particularly in a world where billions of people currently can’t afford access to basic energy services. How can we proceed? Energy Within Environmental Constraints won’t give you the answer. Instead, we will teach you how to ask the right questions and estimate the consequences of different choices. This course is rich in details of real devices and light on theory. You won’t find any electrodynamics here, but you will find enough about modern commercial solar panels to estimate if they would be profitable to install in a given location. We emphasizes costs: the cascade of capital and operating costs from energy extraction all the way through end uses. We also emphasize quantitative comparisons and tradeoffs: how much more expensive is electricity from solar panels than from coal plants, and how much pollution does it prevent? Is solar power as cost-effective an environmental investment as nuclear power or energy efficiency? And how do we include considerations other than cost? This course is intended for a diverse audience. Whether you are a student, an activist, a policymaker, a business owner, or a concerned citizen, this course will help you start to think carefully about our current energy system and how we can improve its environmental performance.

The course “Fluid Flow, Heat and Mass Transfer,” course number ta3220, is third-year BSc course in the program of Applied Earth Sciences at Delft University of Technology. Students in this class have already taken a course in “Transport Phenomena” in the second year, and “Fluid Flow Heat and Mass Transfer” is designed as a follow-up to that class, with an emphasis on topics of importance in applied earth sciences, and in particular to Petroleum Engineering, groundwater flow and mining. In practice, however I start over again with first principles with this class, because the initial concepts of the shell balance are difficult for students to grasp and can always use a second time through. The course covers simple fluid mechanics problems (rectilinear flow) using shell balances, for Newtonian and power-law fluids and Bingham plastics. Turbulence for Newtonian fluids is covered in the context of friction factors for flow in pipes, flow around spheres and flow in packed beds. In heat transfer we start again with shell balances for solving simple steady-state conduction problems. Thereafter, special attention is given to unsteady and multidimensional heat conduction, since the equations are similar for unsteady flow in aquifers and petroleum reservoirs. The concepts of orthogonal conduction and superposition are emphasized, as well as ways to treat perfectly insulated boundaries. The final topic in heat transfer is estimation of heat-transfer coefficients in flow in tubes. Although no other geometries are treated explicitly, I hope students recognize certain principles they can apply to other situations. We cover mass transfer only lightly, and only as by analogy to heat conduction: unsteady diffusion (by analogy to unsteady head conduction) and mass transfer in tubes (by analogy to heat transfer in tubes).

Introduction to seismic theory, measurements and processing of seismic data to final focussed image for geological and/or physical interpretation.This course deals with the most important aspects of reflection seismics. Theory of seismic waves, aspects of data acquisition (seismic sources, receivers and recorders), and of data processing (CMP processing, velocity analysis, stacking, migration) will be dealt with. The course will be supplemented by a practical of 6 afternoons where the students will see the most important data-processing steps via exercises (in Matlab).
