Session 10-1 Cooperative Learning: An Integral Part of Mechanical Engineering Technology Curriculum James Mayrose, David J. Kukulka State University of New York College at Buffalo AbstractStudents are confronted with an enormous amount of engineering content during their course ofstudy. Due to the tremendous amount of pressure placed upon performance in the way of grades,students often look for ways to “cut corners” or do “just enough” to get a decent grade. Studentswill only learn to master engineering concepts

Rogers and Ohrn(2007) pointed out the need for current faculty members to improve productivity andteaching effectiveness in light of the growth in the enrolments in ConstructionManagement programs. The ACCE accreditation requires at least 25 hours ofConstruction Science which can be comprised of introductory-level engineering courses. The class consisted of an equivalent of 3-credit hours of lecture and a 1-creditlaboratory. The evaluation of students comprised of regular homework assignments,laboratory reports, laboratory participation evaluated through an oral examination, a mid-term examination and a final examination.

a conflict cannot be safely investigated withoutpotential hazardous repercussions to the student’s ability to land a job offer or risk “stepping onproverbial toes”.In order to address the contextual conflict resolution and preserve a relative balance of adding newmaterial with an already information rich curriculum, a short role playing module was designed thatcan be put in virtually any engineering course at any level. The entire module takes between 1-2hours total and can be adapted for small or large groups as needed. The idea is to engage thestudents, provide a safe environment in which to role play a difficult scenario, come to someresolution, develop a plan of action and most importantly have fun!

ResultsBased in the grading scheme discussed above, the average grades (followed by the standarddeviation (SD) for each grouping) for the various elements of the course the last three years aretabulated in Table 1. For 2006 and 2007 the grades for the two sections are combined. Theresults in row 3 indicate that the answer to the first question, “Do students learn more frompreparing for the quizzes than they do by doing homework?” is, “no”, as there are only negligibledifferences in the average grades for the classes (2.65, 2.71, 2.63) over the three years.

The proposed drone is such that it could beguided to move and acquire data across any kind of terrain. The concept diagram in Figure 1shows versatility of the drone in terms of its operation terrain. Thus, the proposed design for thenetwork controlled drone is a simplified version to that of the military and is more versatile andaffordable for commercial use. Figure 1.

The energy afteradding the shunt capacitors (i.e. after power factor correction) has been determined from thepower flow solutions. The on-site measurements have been conducted and the measurementshave been verified by the network model that was developed by EDSA software. IntroductionIndustrial power distribution networks experience increase in power losses during summerperiod 1, 4. This is mainly related to the excessive use of air conditioning system and motordrives which reflects an increase in the electric load. Such increase in

The hydraulic system—shown in Figure 1—consists of avertical test tube, two optical measurement systems (reflective and passing), air pressure and flowmeters, and an air compressor. The electronic system consists of a computer-aided data acquisitionsystem (CADAS) and a prototyping board with a Wheatstone bridge, which is interfaced to NIELVIS using a digital oscilloscope.

IntroductionPhotonic crystals (PC) are synthetic materials that can be used to control lightpropagation. PC have a frequency bandgap where light is forbidden to propagate. Thisbandgap is strongly tied to the microstructure of the photonic crystal. Three dimensionalTungsten photonic crystal in a Lincoln-log microstructure has been suggested as analternative filter in photo voltaic cells with significantly high power efficiency.Mechanical characterization of Tungsten PC can be performed using means of micro-indentation. Figure 1 represents the general structure of a bangap for a photonic crystal. Figure 1. Photonic bandgap of PC (bandgap is the region with100% reflectance) Figure 2.

IntroductionThis research examines the potential of using an acoustic bandgap (ABG) material as a sensor forsub-micron (nano) scale damage detection and quantification in composite materials. Acousticbandgap is a physical phenomenon in which acoustic waves are prevented from propagating within arange of frequencies, therefore causing a ‘gap’ (Figure 1). This research exploits this observablefact to develop a novel sensor that can detect damage occurrence at scales not attainable usingexisting sensing technology. We demonstrate here the use of ABG materials to produce a scalablesensor. Scalability allows damage detection at various levels of damage ranging from micro- tomacro-scale damage. This enables us for the first time to observe damage resulting in

Courtesy of Harrop’s Inc.In order to run this equipment, a sample specimen is placed in a fused silica sample holder in contactwith a freely suspended fused silica movable probe rod. The holder and sample are inserted in thefurnace. A control thermocouple is located in close proximity to the heating element for temperaturecontrol. The furnace is heated according to a pre-programmed thermal cycle. As the sampletemperature changes (as recorded by the sample thermocouple), the sample expands (pushingagainst the probe rod) or shrinks (pulling away from the probe rod). The probe rod, which is kept inconstant pressure contact by the pulley system, transmits the
