The paper presents the performance of a collision-free path planner designed for PLM application purposes. The algorithm principle is based on a iterative probabilistic diffusion principle [9]. The paper puts emphasis on efficiency and practicality analysis. It focuses on experiments dealing with disassembly problems as well as robot programming. Efficiency is evaluated in terms of computation ...

Few security mechanisms in wireless sensor networks (WSNs) have been implemented, and even fewer have been applied in real deployments. The limited resources of each sensor node makes security in WSNs hard, as the tradeoff between security and practicality must be carefully considered. While there are many types of security attacks in WSNs, we have decided to focus our analysis on a particularl...
