three, 3-hour laboratory sessions are conducted at the nearby Center forIntegrated Manufacturing (CIM) at Camden County College. The 40,000 square foot CIM centeris a state-of-the-art facility with over $1 million dollars worth of equipment purchased or donatedby companies such as IBM, GE, Texas Instruments, and Bridgeport. At this facility, students aretrained in the basics of manufacturing through the fabrication of a working aluminum-bodyflashlight.Each student machines a MAG-style9 flashlight starting with a 3/4 in. diameter rod of aluminumalloy. The students fabricate the flashlight using both manual and computer numerical control(CNC) machines given a set of detailed dimensioned drawings. At the end of three, 3-hoursessions each freshman

thestudent’s education, data communications and networking are often taught without thepracticality of the laboratory section. However a review of the literature shows increasinginterest in and merits of including a laboratory in a data communications and networking course.One such early work by Smith [1] emphasized a very basic approach to instruct in networkprotocol. His approach of limiting communication to the serial port of the PC’s allowed for thedevelopment of an inexpensive laboratory. A similar approach was presented by Akhtar [2]whose laboratory experiments emphasized different communication protocols. Building onSmith’s work, Classen , et al, [3] outlined the development of a data communications laboratoryemphasizing hands-on experience

gains to achieve specified performance,such a task is design in a narrow sense. To broaden the scope of design, a project wasimplemented with the objectives of: 1. Requiring the student to select the controller structure (PI, PID, state space, etc.), implementation (continuous or sampled) and parameters (such as sampling time); 2. Removing classroom-environment cues as to what type of controller will meet the specifications; 3. Increasing the degree to which the design process is iterative, exploring the capabilities and limitations of alternative controller structures.The project has been used with a second semester course control theory, taken by seniors andfirst year graduate students.1.

The design projectgiven in Statics was to find the optimal placement of the strut for the main spar of a light aircraftas diagrammed in figure 1. The design criteria was to locate the strut so that the maximumbending moment on the spar would be the minimum value possible. The spread sheet calculatedand graphed the shear and moment along the beam using the method of singularities1. In thiscase, the spread sheet for the analysis and calculations was created by the instructor and given tothe students on disk.

Introduction/Rationale.The Electrical Engineering and Computer Science Department at the University of Michigan,Ann Arbor, has recently instituted a major change in its requirements for our undergraduatemajors. We feel strongly that the conventional model practiced throughout the country ofintroducing majors to computing via a high level language programming course is flawed. Ouranswer to whether it is better to start with Pascal, C, or C++ is "none of the above."We have introduced a new course, EECS 100, Introduction to Computing, where the studentsstart from the bottom and work

home appliances. Rapid changes in theindustry, and the increasing use of microprocessors in many of today′s machines lead to productsthat are mechatronics in nature. In order to design such products, an engineer must have generalknowledge of various design techniques and special knowledge of a blend of technologies. Suchskills can be obtained from multidisciplinary mechatronics courses. Recognizing the need for mechatronics education, some Japanese higher educationalinstitutions[1] and European colleges and universities[2-4] offer courses in mechatronics atdifferent levels. Some schools abroad even plan to offer degree programs[5] in mechatronics.The significance of this can be underscored by the fact that there is already an

A four inch diameter of two inchesmust be extracted from the specimen. The side of the specimen needs to be coated with a non-conducting sealant. The sample is placed into a vacuum desiccator at a pressure of 1 mm Hg forthree hours. Afterwards, the specimen is submerged in water without releasing the vacuum.This is done by using a seperatory funnel located directly over the specimen. The vacuumpressure is maintained for an additional hour. Next, the vacuum is released where the specimenremains submerged for an additional 16 to 20 hours. The sample is then secured in

(Raich and Cinar, 1994).Singular value decomposition (SVD) provides a computationally efficient method for PCA. Anym x n matrix A of rank r can be decomposed into the following form (Strang, 1988): A = u1s1vT1 + u2s2 v T2 +... +ur sr vTr ( s1 ≥ s 2 ≥...≥ sr > 0)where si (i = 1, 2, ..., r) are positive scalars in descending order, ui (i = 1, 2, ..., r) are m x 1orthonormal vectors and vi (i = 1, 2, ..., r) are n x 1 orthonormal vectors. The first f terms of theabove decomposition provide the best approximation to A with f principal components.PCA is a linear technique in the sense that it uses linear functions to model relationships between

View windows in the air handling unit reveal moving fans, and at a later date, a window placed into the side of an air duct will reveal streamers placed inside to help visualize air flow. Mechanical equipment, such as pumps, compressors, heat exchangers, etc., is normally hidden from view, but in the ITL Laboratory it is visible through large windows, and students may walk through the two mechanical rooms unsupervised.

One proposed such mechanism is changing majors - the search for a niche where theycan feel comfortable. In order to properly investigate these hypotheses, there are severalnecessary steps:1. Analyze major changes to see if there is a quantitative difference across gender;2. If there is a quantitative difference, investigate if the patterns of changes are different;3. Interview students to find out their opinions of major changing.Investigation of number one above was immediately hampered by the fact that Georgia Techdoes not explicitly keep records of students’ major changes
