Gear - manual, automatic, CVT among others. Efficiency and emissions. Fossil fuel, biofuel - access, cost and performance. EV, HEV - series, parallel, mild, power split, FCV. Conventional servo steering, AC, brake, compressed air and so on. Electrically driven alternatives, function, efficiency. Demands for electric machines and power electronics in vehicles. Criteria for dimensioning. Lifetime, weight, price and so on. Field reduction, starting characteristics, torque ripple and so on. Various types of control, need for sensors. Fuel cells - principle, function and construction. Advantages and drawbacks with various designs. Development trends. Electric storage media - eg batteries and super capacitors. Drive cycles, efficiency, and emission for some selected drive lines. Acceleration, start and other demands for the vehicle. Regenerative braking. The need for effect and energy storage in hybrid and FC vehicles. Assumed prior knowledge: Basic course in physics including mechanics.

The course introduces physical quantities and fundamental laws of electrical circuits. The basics of direct and alternating current networks are explained allowing the evaluation of complex electric networks.

This is an introduction course to the techniques and equipment used in the generation, transmission, distribution, and utilization of electrical power. It gives a basic understanding of how a power system operates and the problems facing electricity utilities. The design and main operating features of different types of motors and generators are also covered.

The goal of this course is to introduce the operation of computer systems at the level of Instruction Set Architectures (ISA). It provides a basic understanding of the design principles that govern modern computer architectures and their components. Special attention is paid to (super scalar) pipelining and memory hierarchy techniques including caches. Implementation and efficiency issues are exemplified. Metrical performance analysis methods are discussed to evaluate architectural alternatives. The course introduces the foundations of low-level computer functioning. The main topics include computer systems, low-level programming techniques, the techniques of RISC processors and pipelining, cache memory, and virtual memory. The course also illuminates the alternative design principles of modern computer architectures in order to provide an understanding of their impact on performance. Quantitative methods to evaluate design principles for performance constitute an important subject of the course.

This class provides training in experimental skills for doing research. Students are required to perform experiments under the instructor's supervision, conduct research, and write a scientific paper.

This course examines modern electric power systems with particular emphasis on generation and transmission. The following topics are covered: the use of three phase systems and their analysis under balanced conditions; transmission lines: calculation of parameters, modelling, analysis; transformers: construction, equivalent circuits; generators: construction, modelling for steady state operation; the use of per unit system; the analysis of systems with a number of voltage levels; the load flow problem: bus and impedance matrices, solution methods; power system transient stability; the control of active and reactive power; electricity markets, market structures and economic dispatch; types of electricity grids, radial, mesh, networks; and distribution systems and smart grids.
