. While some professors prefer that thestudents come up with possible solutions for a project at the early stage of the course andwork on improving those solutions throughout the rest of the quarter, other professors preferthat the students tackle the project theme first without considering what the solutions mightbe. Instead of generating solution first and then later trying to improve the solution so that itwill meet the specifications that are set after the solution is generated, other professors preferto clarify the goals and requirements before generating solutions that will satisfy these speci-fications. Hence even though the outcome of both processes are basically the same, generat-ing solution(s) for problem(s) or need(s), the steps that

This paper outlines the current revolution in manufacturing and design informationmanagement and how the engineering graphics curriculum might respond to it.Engineering graphics technology is currently undergoing changes much more profound than themovement to 2-dimensional (2-D) CAD in the 1980’s. Though there has been some utilization of3-dimensional (3-D) modeling software since the early 1990’s 1, 2, the technology was still beingused primarily as a vehicle for the static documentation of individual parts. For example, reviewof the original syllabus of North Carolina State’s solid modeling course (circa 1989) shows thatone third the semester was spent

Weintroduce for both products and processes, the concepts of material flow; the master equationdescribing the impact on the environment in terms of industrial and economic activity andpopulation; and life cycle. We discuss these topics in relation to the technology S-curve and thepressure on companies to improve their environmental performance. Then, students are asked toconsider how a corporation can use R&D to position itself for improved environmentalperformance through the development of new “cleaner” technologies.

Oneway, typical for the 70's and 80's, but still frequently adopted, is to take a position of a teachingassistant or research assistant at a higher education institution or research institute and pursue - inparallel with routine teaching, research and administrative duties - research work in the selectedarea, under supervision of a senior member of academic or research staff.

higher thetemperature, the more vibration occurs that allows the atoms to let the diffusant through. Forinstance, arsenic in silicon will not diffuse at room temperature and will diffuse only a fewmicrometers after 3 hours at 1000oC. Clearly, solid state diffusion plays a major role in manyfacets of our lives.The odor of a skunk reaching our nose (sensor for smell), even when there is no wind comingfrom that direction immediately brings to mind the diffusion of gases. The time to detect theodor at room temperature over a 10 meter distance might be as long as ten seconds. If diffusionof gaseous molecular species is said to proceed at velocities of up to 103 m/s, why do we notsmell things almost instantaneously? As in the case of solids, the atoms
