implementation of bothconventional and regenerative brake systems on both cars and bikes. Before the initial design(Figure 1) of the RE-Brake system was considered, calculations were made based on bikingstatistics and other energy data to determine how much energy could be gained from such a device.These calculations were done using a few pieces of information, primarily the energy lost when a73-kg person is riding a 10-kg bike at 4.4 m/s. The calculation was done using, 1 𝐸 = 𝑚𝑣 2 2where the mass would be the total of mass of the rider and the bike. The energy of this system wasfound to be about 803 joules, if

It is concluded thatimproving the simulation tutorials, changing the mode of tutorial sessions from face-to-face toonline sessions and changing the quizzes from voluntary to graded quizzes could help to furtherboost the learning outcomes and the direct assessment results.References:1. http://www.thesolarfoundation.org/national/2. http://fortune.com/2017/02/07/us-solar-jobs-2016/3.

a mechanical engineering senior design project with a team offour students.The team worked on the project for two semesters. The results determined that a fully portablewind tunnel would not be possible due to weight and storage size restrictions. Given existinglaboratory sizes and cost restraints, the size of the design was also adjusted. The final design was10.3 m long with the widest section being 1.6 m. The test section was 0.6 m by 0.6 m. Theselected fan had an 8.24 kW power requirement for test velocities from 5.56 m/s to 19.44 m/s.The test section was composed of plywood, except for one viewing panel of Plexiglas. Thecontraction and diffuser were designed as fiberglass. The data acquisition system was not fullydesigned, although some

If the course remains as it is, a stronger emphasizeswill be on topics related to the electric machine dynamic analysis, advanced control, design andmodeling. However, the final decision on the course content is in stand-by, until after thefeedbacks from the 2018 Spring semester industrial advisory board meeting. Any suggestionsand recommendations from 2018 ASEE Conference audience are highly appreciated.Power System Analysis: This course introduces student to power systems concepts, per unitconcepts and notations, symmetrical components, and symmetrical and unsymmetrical faults onthe transmission line.

Google Drive. This practice had several majorbenefits. The most important impact of this practice was that the knowledge and experiencestudent gained in their project accumulated and stored in a single location. The students workingon the same topic had access to the folder as well as the instructor(s). When new students startedto work on the same topic, the Google Drive folder from past teams was shared with them andthey had access to everything the previous team(s) had done and used.The final overall course assessment was according to the following items:  Proposal 15%  Interim report 15%  Final report 30%  Progress reports or meetings 20%  Poster
