One additional explanation is the presence of several supportprograms such as the TWU Multi-Ethnic Biomedical Research Program, the Women IneNgineering (WIN), and the Computer Science, Engineering, and Mathematics Scholars(CSEMS).According to the National Science Foundation1, the percentage of earned bachelor’sdegrees for the year 2000 in science and engineering for underrepresented minorities is15.6%. This 15.6% total in bachelor ‘s degrees earned in science and engineering breaksdown into 8% Blacks / No- Hispanics, 6.9% Hispanics and 0.7% American Indian orAlaskan Natives.

Science, Engineering and TechnologyDevelopment4 made the following statement: As we enter the twenty-first century, U. S. jobs are growing most rapidly in areas that require knowledge and skills stemming from a strong grasp of science, engineering, and technology. In some quarters – primarily information technology – business leaders are warning of a critical shortage in skilled American workers that is threatening their ability to compete in the global marketplace. Yet, if women, under-represented minorities, and persons with disabilities were represented in the U. S. science, engineering, and technology (SET) workforce in parity with their percentages in the total workforce population, this shortage could largely be

Computer-Aided Process Planning(CAPP) has evolved to simplify and improve process planning and achieve more effectiveuse of manufacturing recourses. This paper discusses the benefits of CAPP and how it hasrevolutionized manufacturing. Introduction SurveyIn early 1950's Numerical Control (NC) machines were first introduced, which sparked theresearch and development of Computer-Aided Manufacturing (CAM).

usually translates toassigning design project(s) to groups of students11,12. Such design projects are by definition open-ended and have no unique answer or solution. The students thus have to invoke their imaginationand try to integrate a host of previous classes (i.e. previous knowledge) in order to solve theproblem at hand. This form of learning is considered the ultimate form since it is a replica of realengineering practice. It is worth noting that PBL is already existent in many engineeringcurricula, most notably through senior design courses. It is not common, however, inintroductory engineering classes, like Dynamics, which are typically lecture-based.This paper discusses the efforts by the two authors at coordinating a PBL experiment

Though some mayargue that engineering management started with Fredrick Taylor and his classic text onmanagement titled “ The Principles of Scientific Management,” the specific educational fieldknown as engineering management commenced in the later 1960’s. Bernie Sarchet and MerlBaker started the first engineering management program in the University of Missouri-Rolla.Like any young field of endeavor, engineering management (EM) has undergone some forming,shaping, and its share of growing pains. The field came to be due to the need and demand thatindustry had (and still has) for competent engineering managers.

Buoyancy is not viable in theexperiment because the flow in the test section is moving in the 2 m/s range. Also, theupstream and downstream temperatures, as measured by the thermocouples and HydraLogger, are within a tenth of a degree of one another. When the
