PWCS (Probabilistic Write / Copy-Select) is a new kind of lock-free synchronization mechanism with wait-free characteristics proposed by Nicholas Mc Guire at the 13th real-time Linux workshop, which utilizes the inherent randomness of the modern computer systems. It aims at addressing the multi-reader - single-writer problem in Linux. Based on the original label-based PWCS, we propose a hash-based...
In this paper, the design problem of reverse logistics networks for waste product recycling under fuzzy environment is addressed considering waste product recovery rate. This problem is formulated as a multi-objective mixed integer fuzzy programming. The number of warehousing points, the capacity level of each warehousing point, the location of these warehousing points, and the area covered by each...
The theory of the point-mass model has been widely used to represent the local gravity field. In this paper, the approximation theory of point-mass model is briefly introduced, and the characteristics of the elements in the coefficient matrix for the model construction are analyzed by numerical calculation. The data of gravity anomaly is calculated by using EGM2008 with degree and order 720 in the...
Model predictive control (MPC) framework is becoming more and more attractive in designing vehicular adaptive cruise control (ACC) system. However, benefiting from its advantage, e.g. close-loop optimality, MPC algorithm must overcome some of its practical problems, among which low robustness to model mismatch and computing infeasibility of control law are most critical. Aiming at MPC based vehicular...
