[A] is theconcentration, in moles per liter, of substance A. From the point of view of the mathematician, this is astraightforward, separable differential equation, with A(t) being the concentration of substance A at time t.There are two general forms for the solution, one in the case where n = 1, and the other for all other values ofn. When n = 1, the steps of the solution are: 1. Setup the differential equation: -dA(t) / dt = k A(t). 2. Separate: (1 / A(t)) (dA(t) / dt) = -k 3. Integrate both sides with respect to c ln(A(t)) = -k t + C. 4. When t = O, the value of C can be determined: ln(A(t)) = -k t + ln(A(0)).The mathematician then wants to proceed to the final step and solve for A(t), but the chemist values

A new curriculum, which provides greater flexibility to upper division students to meet their diverseinterests and which enhances the design experience for lower division students, was implemented in Fall,1995 as a result of that effort. A new, four-credit hour "Introduction to Mechanical Engineering" replaced aone-credit hour course in the old curriculum so substantial design and curriculum integration can beimplemented; this course was taught for the first time in Winter Quarter, 1996. Other lower-divisioncurriculum ehancements include three new courses: (a) a one-credit hour, sophomore-level laboratory courseintegrating materials, manufacturing and design was

It had been previously determined that tensile bar number 5 wasthe first to fill and that tensile bar number 2 was the last cavity to fill during injection. Therefore, the massand size of these specimens were measured and recorded. Statistical analyses were performed to measure partrepeatability (mass, length, and thickness) as well as machine repeatability (fill time, transfer pressure, nozzletemperature and barrel temperature). The ABS material was then contaminated with 25% styrene (of similarmelt index). The same process parameters were used, and similarly packed-out parts were produced.

We introduced in our first semester calculus class several functions that are applicable to students’ environment. The postage stamp function and the grading function are examples of step functions, such as the greatest integer function. The greatest integer function, oft, denoted by [t], is defined as [t] = n for every t c [n, n + 1) with n being an integer. Our study of the greatest integer function started with the use of the Computer Algebra System, Derive version 2.0.

The solution to the training problem created two major pedagogical problems. The first problem wasto properly deliver the interdisciplinary content in the three modified courses.

training programs can be categorized into three general areas of centralized, decentralized andintegrated systems. 1 The centralized approach to training exists when the training fimction is controlled orcoordinated from a single organizational source. This approach is very advantageous specially in thoseorganizations with similar operations among various offices, divisions or plants. In the decentralized approachto training, control of the training fi.mction is relegated to various levels and locations of the organization. Thistraining system is utilized where products and services are diverse and therefore central training can only be atgeneral levels. Finally, an integrated approach occurs when parts of both centralized and decentralized

Introduction and Background U.S. firms must increasingly compete in international markets to survive and, as a result, the need forengineering graduates to understand and apply TQM principles has never been greater. Results from severalrecent surveys of U.S. business executives including one published in b magazine [1] consistently suggestthat undergraduate engineering curricula are not doing enough to introduce students to “quality” as a key tenetof engineering practice. Gary Tooker, president of Motorola, has been quoted as saying “We’re not askingcolleges to add courses; we want you to include a quality dimension to existing courses.” [1] This comment suggests that we must

We have successfully incorporated a four weeklong hydraulics and logic control systems component into our required senior level control systems course(outline given in Table 1).
