Experimental SystemA measurement system was developed and built for the measuring of flow patterns using opticalsystems (both hydraulic and electronic). 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.

Data that reflects the impact of this program on student success in STEM fields at UNMwill be revisited through this presentation. Although the program ended nationwide in September2007, NTP at UNM left a great legacy among students, faculty and staff at UNM.

rest are designed inthe light of program educational objectives and Criterion 3 outcomes. These methods were foundto be highly appreciated by ABET in one earlier accreditation process. IntroductionTraditionally, an instructor assesses student performances by giving home works, tests, andprojects, etc. This assessment method is subjective of the instructor. It is well known that duringcourse registration process, many students choose instructors for easy grades. Therefore, gradesdo not always reflect the true merits of students and the programs as well. The real merits of thestudents and programs can better be assessed by determining how really they perform in theirprofessional careers several years

However, inspite of the corrective actions the final grades of the two groups showed distinctdivergence. This prompted the authors to explore Kolb’s Learning Style Theory toinvestigate possible psychological variances among the two groups. The results of thisstudy shows that the Engineering students tend to have a penchant for ‘AbstractConceptualization’ over ‘Concreteness’, while Management students had a preference for‘Active Experimentation’ over ‘Reflection’. Relevant data supporting this finding alongwith a statistical interpretation are provided here. Introduction The

BackgroundFounded in 1932 under the name Engineers' Council for Professional Development, ABET(formerly Accreditation Board for Engineering and Technology) accredits post-secondarydegree-granting programs. Many people interpret this to mean that ABET accredits departments,colleges, or even courses. In reality, ABET accredits programs, and your accreditation workshould reflect the program as a whole.Some programs treat the six-year time lag between visits with the following timeline: - Year 1 – Celebrate success of previous ABET visit. - Years 2-4 – Feel that ABET is a long time away

It is important toengage all students; therefore, any student that is not actively playing a character in the 1st Scenarioshould be a character in the 2nd Scenario. Two scenarios were sufficient to allow the student’s timeto role play the scenarios, come up with a plan to solve the scenarios and allow for classroomdiscussion, feedback and reflection on each scenario.

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.

The two have continued concurrently to allow scholars, scientists, and engineersto understand the natural phenomena of fluid flow and other phenomena in nature. Furthermore, theundergraduate engineering and science curricula also reflect this tradition. However, with theadvancement of high-speed digital computing and the development of accurate numerical algorithmsfor solving physical problems with this new computing technology, we have been introduced withinthe last half century to a new approach in the way we study and practice science.

These products do doubleduty, performing their primary jobs while also saving energy. Roof shingles, for example,may be coated with heat-reflective materials that send the sun's heat away from thebuilding, rather than being absorbed and can even generate electricity for the building.Compact fluorescent lights use less energy and put less heat into the building, andadvances in HVAC technology mean more comfortable spaces that use less energy.The benefits from these components will not be realized

There is little chance that this need in new electricity generation plantswill be satisfied.
