Circle curve fitting is always the important issue of the engineering technology. The effect of circle curve fitting is influenced by both the data quality and fitting method. In this paper, using the special properties of circle, that's the error value of any two radius is zero. Then the method of circle curve fitting was proposed, by finding the minimum error distance between any two fitting points...
Existing bus travel time prediction methods only provide a point prediction value of bus travel time. Relevance vector machine (RVM) is proposed for solving the problem. By using a probabilistic Bayesian learning framework, RVM can provide probabilistic prediction and obtain prediction value and variance of prediction error. For making use of historical data and current information, the running time...
Through mathematical models and game theory, this paper analyzes the optimal incentive contracts between enterprises and their project managers under asymmetric information condition in order to solve the problems in establishing incentive mechanism for project managers. Punishment mechanism is introduced and analyzed in the design of incentive mechanism for project managers. It expands the theoretical...
