SYST 201:Discrete Dynamic Systems Modeling

Fall 2005

 

Course Overview

Rajesh Ganesan

Systems Engineering and Operations Research

George Mason University

 

An important problem in engineering is to predict the behavior of systems that change in time.Such systems are called dynamical systems.This course introduces students to a set of mathematical methods used to model dynamical systems.In particular, students will learn to:

         Identify real world problems that can be modeled as dynamical systems.

         Take such systems and translate them into mathematical models.

         Predict the bahavior of such systems using mathematical analysis and computation.

Students will use engineering mathematics as well as computers to simulate the behavior of dynamical systems and make predictions about the systems.This course focuses on discrete dynamical models in which time is viewed as a sequence of steps.

Homework policy:

 

Try to work them by yourself. Working in groups is permitted but you must make sure that you understand the problems before you turn them in. Please remember that if you havenít learnt the HW problems you may not pass the exams and this will affect your final grade.

All homework must be stapled and submitted on the due date prior to the beginning of the class. Late homework carries a penalty. Only 1 problem will be graded in every HW and the HW grade depends on submitting all assigned HWs and your approach to the problem that is graded.

 

Academic Policy:

 

All academic policies as given in the Honor System and code will be strictly followed. Visit URL

http://www.gmu.edu/catalog/apolicies/#Anchor12

 

Grades:

 

Letter grades will be decided as follows:

93% and above ĖA+, 90-92%- A, 85-89% -A-, 83-84%-B+, 80-82%-B, 75-79%-B-, 73-74%- C+, 70-72%- C, 65-69%-C-, 63-64%-D+, 60-62%-D, 55-59%-D-, at or below 54%-F

 

Exams will only be given at the predetermined dates. Early or late exam taking will not be allowed, except for very special cases.

 

Use of MS Excel is needed for some problems.

†††††††††††

One 8.5x11in. one sided formula sheet will be allowed in the midterm and the Final exam. The sheet must be submitted with the test.††††††††††††††† ††††††††††††††††††††††

 

Please visit http://classweb.gmu.edu/rganesan to check for announcements, Hw problems, and solutions.

 

 

Please turn off your cell phones before class and do not use your cell phone during lecture. Feel free to walk out without distracting the class as and when needed.

 

You will receive some lecture notes as and when itís needed. I will approach every topic by describing the objective, theory, formula and examples.This should make your effort in understanding the course a lot easier.

 

FORMAT REQUIREMENTS FOR COLLECTED MATERIALS

 

Identification: all material handed in must have the following information in the UPPERRIGHT -HAND CORNER; Name, last 4 digits of G #. Multiple pages MUST be stapled. Otherwise pages may get lost and the instructor and TAís will not be responsible.
