IntroductionDesign of complex dynamic systems requires the development of mathematical models withvarying complexities, extensive simulation studies for validation of the proposed models,synthesis and analysis of control algorithms, verification of the performance the closed-loopsystems via numerical simulation, and “hardware in the loop” simulations. As a modern industrystandard, Model-Based Design (MBD) techniques allow for relatively inexpensive designiterations by manipulating parameters of the simulation model instead of costly and timeconsuming

laptop.The UAV is comprised of two primary systems: the autopilot and the airframe. Both systemsmust function together as a whole, which makes it very important that the flight control system iscompatible with the autopilot system. The propulsion system is coupled with the airframeassembly to provide not only thrust but also acts as part of the control system. The autopilotsystem is comprised of the aircraft, on-board hardware, communication links, and ground station. Figure 1.

During the summer of 2010, two civilengineering faculty, one recent alumnus, and one staff member spent five weeks traveling andresearching in communities throughout Zambia, Africa, to investigate program potential. Anassessment of program feasibility was made at three potential sites: the

Comprehension - the ability to grasp the meaning of material. 3. Application - the ability to use learned material in new and concrete situations. 4. Analysis - the ability to break down material into its component parts so that its organizational structure may be understood. 5. Synthesis - the ability to put together to form a new whole. This may involve the production of a unique communication, a plan of operation (research proposal), or a set of abstract relations (scheme for

For the purpose ofharmonic current limitation, the standard divides electrical equipment into four classes as shownin Figure 1. Each class has different harmonic current limits. The balanced three-phaseequipment and other electronic apparatus which is excluded one of three classes are included inthe Class A classification. To apply a Class D limit, the following two requirements should besatisfied:  Input power should be less than 600 W.  Input current waveshape of each half cycle is within the envelope shown in Figure 2 for at least 95% of the duration of each

Development of an Introduction to Infrastructure CourseAbstractAn “Introduction to Infrastructure” course has been developed in the Civil and EnvironmentalEngineering Department at [institution]. The course is intended for sophomore students andserves two main purposes:1. To introduce the students to civil and environmental engineering and the subdisciplines, and2. To begin the development of an awareness of infrastructure and the challenges facing the United States with respect to infrastructure overcapacity and degradation.A particularly noteworthy aspect of the course is that students completed assessments of variousinfrastructure components, inspired by the assessments completed for the “Report Card forAmerica’s Infrastructure” published by the

Engineering at Boise State UniversityI. IntroductionIn recent years, a substantial amount of research has been presented on project-based learning foreducating engineers.[1, 2] It has been observed that this approach fosters a deeper learning andunderstanding of engineering concepts as opposed to the traditional lecture-based coursestructure. In addition, research has documented the prevalence of “Ill-Structured” problems thatengineers face in their professional lives.[3] Posing these types of “problems” in an academicenvironment would better prepare students for higher achievement after graduation, but adoptionis sporadic.A current active research area in engineering education is based on understanding andovercoming the hurdles in transforming from

It is a 17-item instrument. It targets assessmentof specific constructs in the context of collaboration for sustainability based on Fink’s integratedtaxonomy of significant learning. They are: 1) personal agency for sustainability; 2) value ofself-transcendence and 3) awareness of one's limited perspective in situations. The theoreticalgrounding of the constructs derive from Bandura's model of agency, Schwartz's model ofuniversal human values, and Argyris' model of inference, respectively. At the time of thiswriting, the instrument has been completed by

the eight-question multiple choice assessment is 3.46 (SD= 1.50 ). Only onestudent in the sample answered all questions correctly. One question, “What is the main point ofthis memo?” had a 91% correct response rate, while the remaining questions fell between 16%and 48% correct response.Item Difficulty and Discrimination IndexItem difficulty (p-value) is determined by calculating the proportion of students that answeredthe item correctly. The p-value ranges between 0 and 1. While lower values indicate high itemdifficulty, a p-value of 1 indicates all students answered the question correctly.The point-biserial correlations on the other hand provide information on how well the itemdiscriminates between high achieving and low achieving students

There was significant overlap among the problems, with respect to the knowledgeand skills expected.
