a boiler plant whose thermal efficiency is 70+%.Discussion: there is a realistic limit as to how high thermal efficiency can reach. However, tohave thermal efficiency of 70 +% is truly a reflection of inelegant engineering design. It must besecond nature to engineers to maximize this number by optimizing insulation, feedwater preheat,and the amount of combustion air, etc.12. Design an automobile with 15% energy efficiency.Discussion: to say it is OK to live with 85% loss in energy transformation in today’s vehicles is toaccept a quite inelegant way of engineering. Much elegance can be achieved by working toreduce the substantial engine losses as well as losses due to idling and standby14.13. Design using rules of thumb.Discussion: it is

The outputs of the window comparator are then connected to the inputs of the NOR latch.When the output C of the latch is high, the heat must be turned on and when C is low, the heatmust be turned off.The Actuator Whether the heat is turned on or off inside the box, is a reflection of the voltage level atthe output of the latch. When the output is high the heat is on and when the output is low theheat is off. This can be implemented using a relay. The relay interfaces the DC output of thelatch to the ac lamp circuit. The relay is a magnetic switch, which is normally open. The acsource is connected to the

In the remainder of this paper, we present a synthesis of our experiencewith integrating design in existing core courses in the form of steps to be followed in doing so.These steps are consistent with what other writers have reported about teaching engineeringdesign (Miri & Fu, 1993 22; Pascover,199528; Morris & LaBoube,199523; Cairns & Chrisp,1996 5;Ribando & O’Leary, 1998 31; Zhang,1999 45; Dunn-Rankin,19988; and Walter, 2002)42.Pedagogical PracticesUpon reflecting on our success and reading the literature on teaching design, it was

Thus, a new approach is needed to conduct a lab course that is basedon flexible timing and portability of the required work. The developed machine vision labcourses are readily conformable to this new approach, as a large portion of the student workinvolves experimentation with computer algorithms. Another pressing issue in the college is the problem of student recruitment and retention.

Preparation of thesepresentations provides small groups of students with opportunities to reflect together about theirexperiences. Generally, the students learn a great deal by having to clearly explain part of whatthey learned. It is empowering to the students to feel that they are presenting something withwhich their parents are unfamiliar.

Examples of these include enhancing the student’s ability in anumber of professional activities: to use computers in solving engineering problems; to thinkcritically in analyzing engineering problems; to solve open-ended engineering design problems;to function on multi-disciplinary teams; to communicate effectively. All of these outcomesachieved success ratings of 90% (or better) using several metrics; student work productevaluated by faculty and the VCs and a student survey.

The idealteaching would include all the four processes. For example, to illustrate the concept ofheat conduction, the instructor begins with a heat conduction experiment. Next, theinstructor reflects on this experiment, explaining the meaning, and then applies themeaning into abstract mathematical equations. Finally, the instructor gives studentshomework with similar problems.

another location. This system utilizes Acoustic Emission (AE)techniques to monitor tool wear during machining. In effect, it is intended to reflect an un-attended machining situation where a worn out tool can be detected remotely from anyconvenient location, thus freeing up an operator to physically stay at the station and continuouslymonitor the machining process.Several techniques have been developed for monitoring tool condition during machining. AE isan indirect technique in which waveforms can be analyzed and characterized to correlate withthe amount of wear on the tool. In this experiment, a Kistler 8152B sensor was employed to pickup the AE from the cutting interface (Figure 3). This sensor was attached to the tool shank by anM6X10 hex
