<p> Optimization criteria for trap design were established and a qualitative optimization program on the design of two of the most promising series of traps was carried out. </p> <p> An evaluation of several existing traps was carried out using Johnston's technique. Two traps were calibrated and an impact testing device was designed and built for future research work to be conducted at Guelph University. </p> / Thesis / Master of Engineering (MEngr)
