Recommendations are made forusing the teaching of Engineering Economics by graduate students as a component oftheir preparation for the professorate.IntroductionNew educators (i.e., graduate assistants) in the field of Engineering Economics are oftenunfamiliar with the Engineering Economy body of knowledge, as they may not have anydirect experience or they may have been exposed to the field in a different environment 1.While it is uncommon for graduate assistants to not have taken the course that they teach,this unfamiliarity may be more prevalent in Engineering Economy

The College of Engineering at the University of Texas at El Paso (UTEP) developed aprogram for the teaching and learning of sustainable engineering concepts in each and everyengineering program. The departments impacted are Civil, Electrical, and Mechanical &Industrial Engineering, Materials & Metallurgy Engineering and Computer Science.

Mudbricks best feature is that they moderate the temperature due to wall mass. Heat transfers throughthe wall at about 2.5cm (1”) per hourvii so high mass walls tend to even out the temperaturechanges during the temperature cycles of day and night and serve as a heat storage system. Ifproperly designed they can store the sun energy and radiate it back out at night.

Field testing and resultsSignificance of the ProjectThe customary approach used to train technicians is expensive and has some inherentdisadvantages in terms of safety and other health hazards. Although, the use of integrated multi-media tools is not a complete substitute for hands-on learning, preliminary results demonstratethat discreet use and promotion of evolving pedagogical concepts such as just-in-time,contextual, and transactional learning can make training technicians much more efficient,effective and complete (Raschke, 1999

The broadergoal of this paper is to promote the value of peer review in a creative learning environment.BackgroundPeer Review DefinedAny discussion of peer review must start with a basic definition. A peer is a person who hasequal standing with another or others, as in rank, class, or age.1 Ideally, a peer group iscomposed of similarly identifiable individuals but within any definable peer group realdifferences exist between individuals. These differences reflect the level of social status,personality, experience or specialized knowledge each individual has within the peer group

Examples used in the paper will use situations that might beencountered by individuals conducting research in teaching engineering/technical graphics.IntroductionAt the heart of statistics is answering questions with data. According to Finnney, statistics is“concerned with finding out about the real world by collecting, and then making sense of data”(p. 164).1 However, statistical findings are only meaningful if the data are analyzed by using anappropriate statistic test.

simultaneously while presenting an intuitive interface to the user. The iPAQH39703 (Figure 1, left) PDA fit this criterion. This PDA's core processor is an Intel PXA250400MHz X-Scale processor. It runs on the Pocket PC 2002 operating system. Pocket PC is verysimilar to Windows; therefore, anyone familiar with Microsoft Windows would begin to feelcomfortable using the iPAQ rather quickly. The secure digital (SD) slot provides a means toexpand the iPAQ’s internal 64MB of RAM with additional non-volatile memory. This isespecially useful in our application because in the event that the internal PDA battery completelydischarges, the device reverts to factory settings and all personal data and programs not on the SDcard are lost.

The wavelet is an ideallycompact function, i.e., outside a certain time interval it vanishes. Implementations are based onthe fast wavelet transform, where a given wavelet, i.e., mother wavelet is shifted and dilated soas to provide a base in the function space.

One of the great advantages and features of MultiSim is its ability to allow the user to capture its graphics. A major strength of a professional report is the visual presented to the reader. It is true that “one picture is worth a thousand equations.”1 Just take a look at a bridge or large building the next time you pass one. Each of these represents literally thousands of complex equations of which you are viewing the results. Among MultiSim’s capture capabilities is its ability to capture a schematic under design, in addition to capturing a whole host of responses such as
