The concept behind the project is to teach the students not onlyhow the devices work and how to operate them, but also how to characterize and test them. Thus, we had todeal with an array of test instruments as well as the devices themselves. The Equipment EDFA Most mature of the optical amplifiers k the erbium-doped fiber amplifier (EDFA). A practical EDFAsystem has several parts in addition to the doped fiber itself. [See Figure 1] A pump laser producing radia-tion with 980 nm wavelength works well for erbium-doped fiber.

The two faculty assigned to teach the course undertook the detailed course designwith four guiding philosophies: 1) that the design experience should follow a structured, theoretically-based design procedure, 2) that the design project should be realistic: open ended, have a large number of possible solutions, require some introductory level engineering analysis and testing to find the best alternatives, consider cost of the solution in the process, and have a realistic probability that the student team’s design might not satisfy all of the design goal(s), 3) that all

A typical specification sheet for the analog amplifier design would look like this:1- Voltage amplification of 25 times is required.2- The amplifier will be driving a 150 ohms load.3- An input resistance in the range of 1 kohms to 3 kohms is acceptable.4- Both, bias (de) and gain (at) stability are required.5- Maximum voltage amplitude expected for the input signals is 0.04 V.6- The available DC supplies are 1.5V, 3V, 6V, 9V, and 12V.7- - No distortion of the output signal is allowed.8- Select transistor models which are available within the Pspice student version.lo- Try to use commercially available resistors.

This paper discusses the need to change the existing embeddeddigital system design education paradigm, and the efforts being undertaken by the RASSP E&F program towork with the university community to effect this change. The result is a clarion call to stimulate academicparticipation in a progressive educational program that adopts the latest instructional methods and industrialstrength tools to revolutionize the way system design is taught in United State’s colleges and universities.1.

concluded that the normal load on the wall of a storage hopper increases linearlywith depth. The actual load is better modeled by Janssen’s equation (see [1]) which predicts that the normalstress on the bunker wall increases exponentially to an asymptotic value. If a designer were tempted to optimizethe storage hopper design by tapering the thickness of the wall toward the top, the hydrostatic model wouldresult in overbuilding at the bottom and perhaps underestimating the thickness at the top. The hydrostatic modelalso fails to predict the shear stress which a granular material at rest in a bunker exerts on the wall, andneglecting that load may result in a failure of the structure. The fluid-mechanics hydrostatic model also is inadequate

Session 1626 Pattern-based Programming Instruction* J. Philip East, S. Rebecca Thomas, Eugene Wallingford, Walter Beck, Janet Drake University of Northern Iowa/Marist College Several years ago a group of our computer science faculty began seriously examining initialprogramming instruction. We discovered a shared perception that too many students don't write reason-able programs even after completing a semester course in programming. Others have noted the same mayeven be true after the second course (e.g., [1]). There is cause for concern as computer applicationspervade our society, often in life-critical situations. Our students are producing some of

Thus, we can prepare all students for a changing world by teaching them the norms andmethods of design through a pedagogy which embraces those norms and methods. The theoretical and researchsupport for such a pedagogy is also presented.Social Change Technology is one of the forces that drives social change, and it seems to be doing so at an increasingrate. It led to the transition from an agricultural economy to a manufacturing economy to a service economy.Now, with massive corporate re-engineering laying off hundreds of thousand of white collar workers, a neworder may be emerging.1 This time it is information
should be obvious that times have changed with regard to CADsoftware instruction. When graphics meant traditional hand-created 2D mechanical drawing, instruction in the tools was minimal. Astudent, through years of experience, knew how to use the pencil. Now however, for mechanical design, the pencil has changed.Why use professional level CAD software in curriculum? There exists several reasons why we as engineering instructors should dedicate ourselves to integration of professional levelCAD software into the Mechanical Engineering curriculum: 1) As it gains further acceptance, this software has driven many changes in the approach industry is taking to design. Becauseof their flexibility in design variation and their tie to both
First Year Integrated Program at Texas A&M University wasimplemented in 1994 and initially combined the study of engineering, graphics, calculus, physics, and English.Later, the first course in chemistry was added to the program. The first semester then consisted of 2 credits inengineering, 2 in graphics, 4 in mathematics, 2 in physics and 2 in English. The second semester consisted of 1 credit in engineering, 1 in graphics, 4 in mathematics, 2 in physics, 1 in English and 4 in chemistry. Twosections of about 50 students each were chosen somewhat randomly from those entering freshman who werejudged to be calculus ready. After completing the Freshman year the performance of these students wascompared with that of students enrolled in the

Ixthos provide libraries of optimized functions for theSHARC that can be called from C. Over the last ten years, senior students at Roger Williams University (RWU) have implemented a widerange of real-time DSP applications in areas such as communications, controls, and adaptive and multiratefiltering. Those applications, based on both Texas Instruments’ floating-point TMS320C30 and fixed-pointTMS320C25 digital signal processors, are described in references 1 and 2. Investigation of the SHARC was undertaken at the Naval Undersea Warfare Center (NUWC) todetermine its suitability for large processing requirements. Page
the UK is based on nation-wide, standardized examinations. These are somewhat similar to the familiar SAT but far deeper in content and highly subject specific.
