Arm orthosis body mount

This Major Qualifying Project (MQP) deals with the design of a body mount to be used in conjunction with a powered arm orthosis. Previous groups designed and built the orthosis with the intent that people with Muscular Dystrophy (MD) would use it as an assistive device. In this MQP, a new body mounting system was designed for the arm orthosis. Due to the fact that the orthosis was built for people with MD, it was essential that the design specifications of the body mount account for the specific wants and needs of the users as well as the function of the orthosis. Four prototypes were designed, built and tested. The final design was derived from the prototype that performed the best during testing. A CAD model was developed that can be used to construct an improved physical prototype

DNA fingerprinting.

This project describes the basics of DNA fingerprinting and shows its importance in the field of forensic science. Using the vast resources of the Internet, as well as scientific journals, we provide background on the subject of DNA fingerprinting. We develop this project in layman's terms so as to be read by jurors and lawyers. Based on our research, we conclude that this powerful new technique, when performed correctly, has the potential of becoming the greatest forensic tool in the history of science
