A cash-constrained two-level supply chain with a supplier and a single retailer facing stochastic demand is considered in this paper. Two different financing strategies are investigated and the resulting expected return of the supplier, retailer, and bank are examined. Our numerical study shows that by sharing revenue and risk among supplier, retailer, and bank, the joint financing strategy can improve...
An increased frequency band requires a more accurate pointing ability in large antenna. Accurate tracking by large antenna must be assured during changing weather conditions. However, because of the outdoor nature of their operations, and especially for those with a low natural frequency, the antenna could be severely influenced by the wind disturbances. Furthermore, it would be difficult to compensate...
Tire model for vehicle braking performance simulation analysis has been built in this paper. Through theoritical analysis, the expression of longitudinal force, side-force and self-aligning torque of the tire in joint working conditions was obtained. By means of neural network module in MATLAB, BP neural network model of the tire in joint working conditions was built. Vertical load, slipping ratio,...
Based on the Hotelling Model, this paper construct an overlapping business competition model about bilateral platform enterprise. Focusing on the platform of two situations that one is single attribution while the other is multipartite attribution. This study analyzed both the existence and the structure of the equilibrium solution, and three main conclusions were drawn up. Finally, the study tested...
IEEE 802.15.4 standard provides a viable MAC and PHY specification for wireless sensor networks. Performance evaluation of these networks has been reported in literature. Previous works focus largely on analyzing the CSMA/CA traffic and frame delay due to Guaranteed Time Slots (GTS) allocations. In this work, we propose a analytical model to understand and characterize the performance of GTS traffic...
A compact model has been developed to capture the variability of flicker noise resulting from the reduction in size of state of the art MOSFETs. The underlying physics of flicker noise in small area MOSFETs has been verified by two means: Monte Carlo simulation and analytic modeling. The statistical distribution of flicker noise is reported for the first time, supported by experimental data from two...
