yearsprogramming is still considered to be a difficult course demands the location of a new, probablyearlier, starting point, and different methods and media to teach it. “Programming is a very usefulskill and can be a rewarding career. In recent years the demand for programmers and studentinterest in programming has grown rapidly, and introductory programming courses have becomeincreasingly popular.”4 Since the early 70’s there has been an intense effort towards determiningand adopting appropriate and efficient methods that would optimize the learners’ ability tounderstand and solve programming related problems. 4, 5 For these reasons, identifying theoptimum way to teach programming and algorithmic thinking has for decades been one of thebiggest

thedesigner to modify their design for getting a better product. Magnet field analysis may also beused for finding torque, force, power losses, and induced voltage, which are the primaryparameters of electrical machine performance study.This paper presents the magnet field analysis of a cylindrical permanent magnet linear alternator.This alternator has four permanent magnet rings mounted on a plunger (shaft), which oscillateslinearly when the machine is working. The magnetic polarities (N pole or S pole) of the rings arein radial direction and the polarities alternate from one ring to the next on each side of theplunger. Two of the magnet rings are on each end of the plunger and a magnetic loop is formedby the permanent magnet rings, plunger, stator

technical specificationsWhen designing either a transformer or an inductor, a wire is required for the winding(s) aroundthe magnetic core. Wire selection is typically based on the window area of the core as well astolerable amount of copper losses in watts. The web-based magnetic design contains a sub-routine that automatically looks for the wire size (gauge) that most closely fits the calculatedcore material and type. However, since the program is meant to aid in basic calculations ofsimple inductor and transformer designs, the wire selection does not take into account complexconfiguration of winding such as bifiliar or more, interleaving, etc. Figure 5 illustrates the stepwhere wire size is determined including three data related to the selected

inthe Spring of 2010. Both graduate and undergraduate students, faculty, private consultants, andpublic servants are provided with the opportunity to learn from each other during this weeklyone-hour seminar. The establishment and overview of the seminar series are discussed along with thedevelopment of guidelines for student attendance. Involvement of faculty, students, andprofessionals was evaluated. Attendance at each seminar is a function of topic(s), presenter(s),and time commitment conflict (schedule conflicts with other classes or faculty sabbatical).Based on data from the Spring 2010 and Fall 2010 semesters, faculty attended 41 percent of theseminars, and students attended 43 percent of the seminars.

No modifications of thechassis were permitted. Alternative gear designs and mechanisms were an option forbonus marks.

: • “I think that after completing this project, I have a better understanding of the entire design and manufacturing process”; • “I view a 5 as near perfect, which is the reason for more of the 4’s”; • “It was a good learning experience”. Feedback from the collaborators, regarding the teams development, experiences, as well as the industry-defined competency of the developed assistive device were also extremely important during the semester. This provided a partial summative evaluation of the project and the students’ learning. Further summative evaluation of the project, regarding the usability and quality of the products, is expected to be provided by the users of the assistive devices. Lessons Learned

Implementation of the herein suggested inflatable structure would reducethe weight of these competition aircrafts.
