Electron Beam Coupling Efficiency in EBF3 Rodney M. Clayton, Missouri University of Science and Technology, Department of Materials Science and Engineering, Rolla, MOAbstractThis study examines the coupling efficiency of the electron beam to a metal substrate in theElectron Beam Freeform Fabrication (EBF3) system. EBF3 is a type of additive manufacturingfor metallic parts that uses an electron beam as an energy source. This type of additivemanufacturing is of significant interest to NASA because of its ability to manufacturecomponents for aircraft and spacecraft or repair parts while on long duration space missions. Tomake accurate models and computer

Assessment of an Individualized, Self-Contained System in Electrical Circuits Laboratory E. Carl Greco and Jim D. Reasoner Electrical Engineering Department – Arkansas Tech UniversityAbstractA pilot study was performed to evaluate the efficacy of a teaching protocol employing anindividualized, self-contained laboratory system for instruction in a fundamental electricalcircuits laboratory. For purpose of evaluation, students were divided into two academicallymatched groups. The control group utilized traditional laboratory equipment and performed theirweekly laboratory assignments as two member teams. The study group used the ElectronicsExplorerTM Board (EEBoard

A visit to the health clinic will also provide an opportunity to see if there areimprovements to overall health in the community as a result of this project.Proceedings of the 2012 Midwest Section Conference of the American Society for Engineering Education 6Due to the large community support and excitement, the EWB-TU team anticipates seeingreplicas or variations on this design elsewhere in the community. It is hoped that the communitymembers will take the technology and knowledge that was given to them and apply it to

Communications Commission (FCC) to deliver classes to studentsin remote locations (Casey, 20081.) In 1934 the University of Iowa delivered the firsttelevised class to students (Casey, 20081.) The FCC followed this by creating a band of 20television channels (known as the Instructional Television Fixed Service) to deliver low costcourses to the nation in 1963. New technologies have enabled the development of many newsynchronous and asynchronous methods.With the new technologies available for delivering distance education, there is relatively nolimitation to the development of delivery systems that can cater to all learning and teachingstyles. During the summer of 2011, the dean of the engineering college of a Midwestuniversity approached the other

Overall architecture of the test IC.Initial SolutionThe first attempt to get very fast signal speeds was to use the logic gates delays to build signalsfaster than the clock – essentially creating signals using glitches in the logical circuit (Figure 2).While this method works, it is inflexible and challenging to implement, since any changes to thesignal requires the creation of a new custom circuit.Proceedings of the 2012 Midwest Section Conference of the American Society for Engineering Education Figure 2.

optimized for energy efficiency in passenger vehicles and light weight delivery vehicles. This project continues to build a bridge between local business, industry, and the University of Arkansas – Fort Smith in motor development and specialized parts needed in this powertrain. As this technology matures, it is foreseeable that new businesses and industries could result. Battery Electric Vehicle Specifications The second generation BEV uses a 335 V system is powered by GBS LiFeMnPO4 batteries; these 60 Ah batteries are rated at 3 C to allow a constant output of 180 A for one hour and 600 A for 10 seconds. The prismatic battery set weights 550 pounds with an energy density of 100 Wh/kg. This second generation vehicle incorporates a

Using Moodle for Algorithmic Grading of Homework Assignments Robert Fithen Arkansas Tech UniversityAbstractThis paper will explore the use of Moodle to grade numerical based homework assignments.Particular interest will be paid to Moodle's ability to supply a different set of numericalparameters for every student in the course. In addition, Moodle's ability to adaptively gradethe homework makes it particularly attractive to faculty interested in reaching an onlineaudience. Implementations in a typical fluid mechanics course will be explored in detail.Moodle is a learning management system used for online or mixed technology type courses.It is freely available as a
