For problems involving uncertainties in design variables and parameters, a bi-objective evolutionary algorithm (EA) based approach to design optimization using evidence theory is proposed and implemented in this paper. In addition to a functional objective, a plausibility measure of failure of constraint satisfaction is minimized. Despite some interests in(More)
Two types of computer input devices, a conventional mouse and a roller bar one, were studied in terms of muscular activity in m. trapezius dexter, m. deltoideus anterior dexter and m. extensor digitorum dexter, and comfort rating. Fifteen university students and employees participated in this study. The order of the devices was random. While a task was(More)
Introduction Quantum key distribution (QKD) [1] enables two remote parties Alice and Bob to share common secure keys which are unknown to a potential eavesdropper. Unconditional security of QKD is based on the fundamental laws of quantum mechanics, but in reality, securities of practical QKD systems could be jeopardized by physical implementations. In(More)
