The course consists of a sampling of topics from algebraic combinatorics. The topics include the matrix-tree theorem and other applications of linear algebra, applications of commutative and exterior algebra to counting faces of simplicial complexes, and applications of algebra to tilings.

This course provides an introduction to algebraic number theory. Topics covered include dedekind domains, unique factorization of prime ideals, number fields, splitting of primes, class group, lattice methods, finiteness of the class number, Dirichlet's units theorem, local fields, ramification, discriminants.

The SAT is a timed standardized test, taken by most students in their junior or senior year of high school, often required for college admission. In the increasingly competitive college admission process, students today are looking for any and all ways to improve their candidacy. One element of your college application that can definitely be improved on to help your chances of admission is your SAT score. The test is made up of 10 sections, drawn from three subjects: reading, mathematics, and writing. All of these subjects review topics you have already learned in school: critical reading skills, arithmetic, algebra, geometry, grammar, and essay writing. You already have basic knowledge on these subjects. However, you can gain an extra edge and improve your score by reviewing the specific material that will be covered on the test and by becoming familiar with the rules and strategies specific to correctly answering SAT questions. Doing well on the test provides important information about you as…

**Course Summary**

In this first part of Vehicle Dynamics, we illuminate the longitudinal dynamic aspects of vehicles.

**Clear and brief:** acceleration and braking.

**In Detail:** After an introduction, we will look at driving resistances and slip, explain the demand of power and limits of a car, then clarify the needs for a clutch and gears and look at the rear and front weights during acceleration and braking. The course will be finished by two applications from automotive mechatronics.

**What will I learn?**

By the end of the course you will …

- understand basic principles of accelerating and braking a car.

**Course Summary**

In this second part of Vehicle Dynamics, we will illuminate the lateral dynamic aspects of vehicles.

**Clear and brief:** the cornering of a car.

**In Detail:** We will start with a simple single-track model and then describe the slip angle of a wheel. The slip angle results in cornering forces, which are essential for understanding lateral dynamics. After that, we will look at the dependency between longitudinal and lateral forces using Kamm’s circle and Krempel’s diagram. Then we will investigate steady state cornering, stability and the influence of different weight distributions between inner and outer side wheels of the car. The course will finish with two applications from automotive mechatronics.
