The S-Lprogram has been supported by three grants from the National Science Foundation. In this effort,the S-L projects are hands-on experiences in core courses of every engineering department,aimed at responding to community needs. The community partners can be local, national orinternational. Most of the S-L projects require the students to assess the engineering componentsof community needs, to design solutions

The National Science Foundation(NSF) Scholarships in Science, Technology, Engineering, and Mathematics (S-STEM) programstrengthens these efforts by providing funding to not only implement programming to supportthe recruitment, retention, and graduation of low-income S-STEM students; they also fundscholarships exclusively for students that meet designated academic and financial conditions.Prior research highlights that Historically Black College and Universities (HBCUs) enroll adisproportionately high

model example, we propose to evaluate the position, velocity and the time at which the 1pound block leaves the surface of a cylindrical surface on which it slides. The block is assumedto have an initial velocity V0 at the top of the cylinder and is subject to a constraint friction forceof kinetic coefficient of friction, µk (See Figure 1). To achieve a stable numerical solution, weassume, without loss of generality, a specific initial speed of 10 ft/s for the block and considerthe coefficient of kinetic friction between the block and surface to be zero in one case and 0.2 inthe other. The radius of cylinder, r = 5 ft. V0 r

difference in these purecircular motion problems versus one-dimensional motion along the x or y axes is that theresultant acceleration vector will have two components.In addition, an angle will need to be calculated between these two acceleration components.There will be no formulas that contain standard rotational variables such as ω and α.Also, a new notation for the introduction of time will be introduced. For example, with an initialvelocity of 1 m/s and a given tangential acceleration how long will it take (t) to reach a finalvelocity of 4m/s? The notation will be as follows (1m/s, 0s) and (4m/s,ts)This alternative method eliminates the need for plotting variables in a two-dimensional graphwith time on the horizontal axis. Except for the
,general feedback block diagram. The equivalent transfer functions (pre-filter and feedback) areobtained by means of superposition. Then, all the blocks are reduced into a single transferfunction by means of the simplification formula: P(s)G(s)/(1+G(s)H(s)). The resulting transferfunction shows the gain for each configuration (-RF/RA for the inverting Op-amp and 1+RF/RAfor the non-inverting configuration) and bandwidth. It also shows that the Gain*Bandwidthproduct is constant for the non-inverting configuration, but not so for the invertingconfiguration. This approach is straightforward and insightful, specially for those students whohave previously been exposed to feedback theory and who have backgrounds in fields other thanelectronics.I

explore a new non-comparison sort. The linear transform sort uses alinear transformation to generate new keys between 0 and n and uses those keys to sort the datausing a recursive bucket sort. The idea of using new computed keys is adapted from theSchwartzian Transform [4], where a sorting key is extracted from other extraneous data all atonce instead of repeatedly during runtime. This sort is a proof of concept that transformation can adapt the input of non-comparisonsorts to increase speed of sorting. We will outline the linear transform sort algorithm, inductivelyprove its functionality, outline best and worst cases, present test data, and propose improvementsfor further research.Algorithmlinear transform sort(S)Input: a list of

Thus, thestudy of Modeling and Simulation (M&S) should be included in any engineering program.Unfortunately, the basic foundations of the area are not being taught; university courses in M&Shave shifted from the introduction and use of formal techniques to application of softwarepackages, such as Arena. While the use of application software is a favorable teaching tool, theprograms do not allow students to fully understand and appreciate the underlying concepts ofM&S. For example, a large part of M&S is in Verification and Validation (V&V). There arefour V&V categories of techniques for simulation models: Informal, Static, Dynamic, andFormal, yet students who
