Improving contour accuracy is one of the significant goals industrial machining. This paper proposes a error estimation and compensation algorithm for five-axis computer numerical control (CNC) machine tools based on modified (NC) codes. The expected path analyzed by NC data actual trajectory collected sensors are spatially mapped hidden Markov model (HMM). Next, an evaluation function that hyb...

When transacting and interacting through open computer networks, traditional methods used in the physical world for establishing trust can no longer be used. Creating virtual network substitutes with which people, organisations and software agents can derive trust in other parties requires computerised analysis of the underlying trust networks. This article describes an approach to trust networ...
