reflects culture and includes the diversity characteristics inextricablylinked to culture. Architecture inherently possesses a certain formal nature, which can beevaluated. The approach to identifying diversity-defining characteristics is intended to revealkey indicators inherent to primary form responses. These indicators, in part, grow out of basicarchitectural determinants of form and may be simplified into the following taxonomy of threegroupings of factors: external (PLACE), internal (PEOPLE) and the in-between(ARCHITECTURE) indicators. External indicators present opportunities for integration ofcultural and contextual diversity. Internal indicators provide opportunities for the domain andspecific detailed user or people related diversity

Problem-solving • Analytical SkillsThis indicates a high level of interest and effort in the class throughout the semester.Besides igniting interest in robotics for the students in the class, we had an unintended effect ofexciting a class of about 24 preschool children who came to participate in a final testing stage.During the official DARPA Urban Challenge on Saturday, November 3rd, 2007, the students heldtheir own mini Urban Challenge in the lobby of the student dorm. Although it was interesting foronlookers, results were not as hoped due to the early date. In one case, the robot traversed theentire route, but didn’t detect another vehicle at an intersection. The obstacle didn’t reflect theultrasound back to the robot’s sensor. In another

This has by no meansguaranteed that ethics education for U.S. engineering undergraduates is of a uniform content,quality, or depth.4 Nonetheless the movement appears to be clearly in the direction of morecoverage, whether in the form of stand-alone ethics courses or ethics modules embedded inexisting courses; at the very least, engineering programs must show that their graduates havebeen exposed to ethics content to a level adequate to satisfy evaluators.The underlying presumption of such

In the latter case, the team must committo regular meetings to coordinate lecture and homework assignments in order to minimizeoverlap in material and provide a smooth transition from one instructor to the next.

ConclusionIn order to create plots "on-the-fly" at the lectern, ultimately, program instructions must beentered into a computer. Although applications such as Matlab® have made plot creation fairlyeasy, it is nonetheless challenging to quickly create and format plots in such a way that they areeasily readable in a classroom, and also easily and clearly demonstrate important points of

same admissionsrequirements.” While it is true that medical schools have come to expect a standard array ofbasic science courses prior to matriculating, it is also true that some medical schools indicatehaving no requirements of particular classes; the MCAT is their principal measure of mastery ofbasic sciences. Indeed we have seen no evidence amongst our graduates that any medicalschools reject students for lack of a particular undergraduate class.One reason for this may be reflected in another free-response: “Be certain that this plan of studyis strongly endorsed by UVa’s premed advisor. Med schools are guided by that endorsement.”Most institutions have the equivalent of an office of pre-professional studies. We work closelywith advisors in

Studying the relationship between product quality and diagnostic reasoning is a fruitfularea of future study. The results of this case-study comparison preliminarily suggest thateffective diagnostic reasoning may be related to better product design, since such a capabilityenables designers to learning more from product testing. When effective diagnostic reasonsersperform more design iterations, they may achieve greater insights into their devices and discovermore features to improve while still working within the time-constrained setting in which mostdesign work takes place.

A simple cylindrical lens optic produced the desiredsheet of light for illumination of a section of the test section. The top of the test section, as wellas the side-walls, are of Plexiglas for optical access. Not all of the flow field could be viewed atthe same time with the current optical setup due to the spreading of the laser light sheet.

Inorder to validate their designs, students use eight custom-made speed sensors that they attach tothe coaster track to measure the speed of the coaster car at critical locations along the track.Speed measurements are captured in LabVIEW, analyzed, and submitted in a final report asevidence of how well the Excel design model reflected the actual behavior of the roller coaster.The project
