The study of robots has received a considerable amount of attention in the past two decades. The term“robot” was mentioned in the literature as early as the 1920’s. It was, however, not until the late 1970’s that acommunity of scholars dedicated in this subject emerged. The field of robotics is unique in that it incorporatesmultiple disciplines: specialties include computer science, mechanical engineering, electrical engineering,physics, and mathematics, to name a few. Due to this interdisciplinary nature, constructing a robot requiresunderstanding of various facets of the aforementioned areas of expertise. By the early 80’s the technology had matured enough to produce robots with reasonable size, weight,and capability. Robots can now

INTRODUCTION In the early 1970’s, the School of Electrical & Computer Engineering (ECE) at Purdue Universityadopted a course & instructor evaluation system to be used in all courses (undergraduate and graduate, lectureand laboratory classes). The evaluation system adopted was based on a series of questions that students couldrespond to using a five-point scale, with answers ranging from "strongly agree" to "strongly disagree" (the Pur-due Center for Instructional Services has compiled a large set of such questions — referred to as theCAFETERIA System — from which "customized" course & instructor evaluation forms can be

A well-founded assessment plan has three components. The first is a statement of educational goals.It is necessary to define exactly what is expected of students. The second is a valid set of measures ofachievement of these goals. As in any good experimental design, multiple measures are best. The third, andperhaps the most important and difficult component, is use of the information gathered in order to correct andimprove the educational process. In order to develop an assessment plan, educational goals must be defined. It is necessary to definewhat

Additional topics in the areas of teacher-student relations,ethics, tenure/promotion and time management are also addressed. Participants will prepare and present classes,be critiqued, and critique others. They are also expected to interact with faculty at their home institution toimprove the teaching of others. The short course has at its roots a teacher training program that has been ongoing at West Point since the1940’s. The paper will briefly discuss this highly successful program and its relation to the planned short course.In addition to the authors, the latter two who have for many years run the aforementioned teacher trainingprogram, other West Point faculty

A variable pitch NACA 0015 symmetric airfoil equipped with 11 surfacepressure taps spans the tunnel test section and a multi-tube water manometer board is used tomonitor the surface pressures and provides a visual display of the dynamic changes associatedwith varying angles of attack. A Pitot-static (Prandtl) tube is mounted at the front of the testsection to measure the static and impact pressures required to determine the flow velocity. Thedynamic pressure from the Pitot-static tube is measured using a Betz manometer, which isremotely observable using a webcam.The pressure from the airfoil pressure taps is measured using a Scanivalve® pressure transducersystem that

Clearly defined visualization(s) thatdepict the expected outcomes from each phase of construction can be generatedbeforehand and these can be embedded into the framework as shown below. For instance,in Figure 4, the two visualizations show the finished stages of construction at two phases.Any lags or setbacks in construction (in the real-time) can be compared with the pre-planned designs and faults and delays can be easily identified. This facilitates a moreconcrete evaluation and hence decision-making rather than relying on abstract or vaguemilestones.

example,according to an electromagnetic signal attenuation test performed at the U.S. National Institute ofStandards and Technology (NIST)’s Gaithersburg laboratories, the signal attenuation for ½ inchdrywall and plywood is below 1dB around 2GHz frequency band.10 However, if a house is builtusing steel frames or with a concrete structure (e.g., high-rise apartment buildings and hurricane-resistant houses), the 802.15.4 transmission performance is expected to experience greaterdegradation by the house structure than from the nearby wireless signal interference, especiallywhen the 802.15.4 signal needs to be transmitted over a long range and pass through walls. Thisis because steel frames partly reflect radio signals and create multipath
