Feedback was given on these agreements sothat students had all discussed how to deal with conflict, differing work ethic, and how to bestrespect each other’s ideas. The schedule and plan of progress reports were outlined in thesyllabus on the first day of class for the students.

In this model, students from an engineering departmentwould be assigned a capstone project focused on designing a system that primarily centered onthat department’s discipline. ABET and the National Academy of Engineering (NAE) began initiatives that changed howinstitutions, departments and programs thought about capstone design courses and projects.

Then they compared the strength,burning rate and duration of burning of the briquettes, as well the difficulties to obtain binderand process the material. They finally settled to an easy to follow recipe and a very simpledevice to press the loose shells to briquettes. In the January of 2012, a student team went to 8remote villages in rural Gambia. They demonstrated the briquetting process to the local people.The team was warmly received and all villages agreed to try out the method so they couldpreserve the dwindling forest while supporting the growing community.1 IntroductionThe Gambia is a small country located at the tip of West Africa.

Thepurpose of these courses is for student engineers to apply what they have learned in previouscoursework toward the design of a project within specified constraints. As ABET criterionstates, “Students must be prepared for engineering practice through a curriculum culminating in amajor design experience based on the knowledge and skills acquired in earlier course work andincorporating appropriate engineering standards and multiple realistic constraints [1].”We’ve had some success in incorporating service learning activities into our capstone designcourse [2].

Inadequate reactive power leads to voltage collapses and hasbeen a major cause of several recent major power outages worldwide 1. Reactive powercompensation can be provided by using FACTS devices, which are power electronics-baseddevices that control and regulate the power flow within the power system. They are capable toreroute power through the optimum available paths regardless of the dynamics of the powersystem.
