OFFICE HOURS: W 4-5pm, TTh 1:00-3:00pm, by appointment all other times

COURSE DESCRIPTION:

The understanding of a variety of numerical methods is crucial to solving most high-level applications in engineering, physics, chemistry, and biology. This course, recognizing this fact, emphasizes case studies in a number of areas including mechanical, civil, environmental, electrical, aerospace, chemical, and biological engineering. Subjects to be studied include error analysis, roots of non-linear equations, systems of linear equations, optimization, curve fitting including splines, Fourier analysis, modeling, numerical differentiation and integration, and numerical solving of differential equations including, but not limited to, predictor-corrector methods and finite element analysis. Extensive surveys of a number of advanced subjects include digital filters, molecular dynamics, percolation, and Monte Carlo simulation methods. Some new mathematical concepts will be introduced in the class. A number of software packages important to engineering are surveyed with primary emphasis on MATLAB.

PREREQUISITES:

MAT 242. Some knowledge of computer programming.

COURSE LEARNING OUTCOMES:

Upon successful completion of the course a student will be able to

1. Give an error on solutions to numerically solved problems and qualify that error.

2. Demonstrate the ability to use the appropriate numerical methods to solve complex science or engineering problems.

3. Use a software package to aid in the solution of a complex science or engineering problem.

4. Solve for the roots, minimum, and maximum of an equation, solve a system of equations, fit a curve to a set of data, and perform numerical differentiation and integration.

5. Perform a rudimentary Fourier analysis.

6. Demonstrate an understanding of the numerical techniques to solve differential equations.

TEXTBOOK:

Numerical Methods for Engineers 5th Edition. Chapra, Steven and Canale, Raymond. McGraw-Hill. (2005/2006).

OTHER REQUIRED COURSE MATERIALS:

Handouts on material not covered in the required textbook to be distributed in class throughout the semester.

OUTSIDE CLASS REQUIREMENTS:

As with any class an amount of time at least equivalent to two times the credit hours is expected to be performed for homework and labs. Note that this is an advanced class so expect to spend significantly more time on outside work than in most class.

Evaluation of student performance is to be based on:

1. Four extensive projects will be assigned that will constitute 60% of the total grade.

2. A four to five page essay surveying the material in the course. This essay is to include not just the methods but a practical guide on to when to use different numerical methods. This is worth approximately 20% of the semester grade.

3. A number of short homework exercises emphasizing various concepts which will be worth approximately 10% of the grade.

4. A final discussion which will be graded on participation and will be worth approximately 10% of the grade. This will be a group activity. Participation includes showing up for the discussion, being an active member of the discussion, and putting forth reasonable ideas.

HOW ASSIGNMENTS ARE TO BE SUBMITTED

1. Homework is due at the start of class (or before) except for in-class projects.

2. Make-up homework, quizzes, and/or tests are up to the discretion of the teacher (excused absences only). No makeup will be possible for laboratory work, sufficient time should be available to recover if an absence is necessary.

The Blackboard Login Procedure Has Changed For ALL Students

HOW TO LOG IN TO BLACKBOARD (note these class does not use blackboard)

Blackboard is a web-based program that serves as the college’s online classroom. You will use Blackboard to communicate with your instructor, to see your course materials, to submit assignments and to discuss course ideas with your classmates.

• Go to the Prince George's Community College Blackboard web site which is located at http://pgcconline.blackboard.com. NOTE: There is no “www” in the Blackboard address.

• If you do not have a myPGCC account, you will need to create one:

The first time you access Blackboard using your myPGCC account, you must change your myPGCC password to access Blackboard. When you change your myPGCC password, the Blackboard system is updated with the myPGCC account information.

• Once you have your myPGCC account information, type it in the Blackboard login box at the http://pgcconline.blackboard.com. (Write down your account information so you can refer to it if you forget.)

• If your login is successful, you will see the Blackboard “Welcome” screen. In the box labeled “My Courses”, you will see the course or a list of courses in which you are enrolled. Click on the course name to enter your Blackboard course.

DISABILITY SUPPORT SERVICES

Students requesting academic accommodations are required to contact the Disability Support Services Office (M-1042) or call (301) 322-0838 (voice) or (301) 322-0122 (TTY) to establish eligibility for services and accommodations. Students with documented disabilities should discuss the matter privately with their instructors at the beginning of the semester and provide a copy of their Student/Faculty Accommodation Form.

CODE OF CONDUCT

The Prince George's Community College Code of Conduct defines the rights and responsibilities of students and establishes a system of procedures for dealing with students charged with violations of the code and other rules and regulations of the college. A student enrolling in the college assumes an obligation to conduct himself/herself in a manner compatible with the college's function as an educational institution. Refer to the 2005-2006 Student Handbook, beginning on page 41, for a complete explanation of the code of conduct, including the Code of Academic Integrity and the procedure for dealing with disruptive student behavior.

The college is an institution of higher learning that holds academic integrity as its highest principle. In the pursuit of knowledge, the college community expects that all students, faculty, and staff will share responsibility for adhering to the values of honesty and unquestionable integrity. To support a community committed to academic achievement and scholarship, the Code of Academic Integrity advances the principle of honest representation in the work that is produced by students seeking to engage fully in the learning process. The complete text of the Code of Academic Integrity is in the 2005-2006 Student Handbook (pages 42-45) and posted on the college's website.

CLASSROOM POLICIES

1. Food and drink in limited quantities (snacks, not meals) are permitted in restricted areas (not near electronics) and will be revoked if proper cleanliness is found wanting.

2. Cell phones must be in vibrate mode and are only to be answered for emergencies (step outside please).

3. Common courtesy is to apply at all times.
