The wireless sensor networks (WSN) is one of the most significant technologies in the 21st century. In recent years, achievements in micro-sensor technology and low-power electronics make WSN become realities in applications. In this paper, we propose a system for WSN based on environmental monitoring. The system can monitor several environmental parameters(More)
Combined the advantage of Hopfield neural network and filled function method, a dynamic filled algorithm will be presented for constrainted global optimization of nonlinear programming. The algorithm contains two phases. The dynamic minimizing phase in which the dynamic minimizing system is used to find the local minimizer of the global optimization. And in(More)
The goal of this project is to create a muscle-based facial model which can be used to generate realistic facial animation. Maya software was used to set up the facial muscles, and attach them to the facial geometry so that changing the muscle parameter values will deform the shape of the facial model. To create smooth animation, one can change the(More)
To achieve energy-saving and environmental protection, electrical heaters play an important role in the heating system in some northern regions of China. To achieve the centralized controlling and meet the different requirements of every heating unit, distributed control system that is applied to electrical heaters of public building is a better way to(More)
In this paper, channel allocation scheme is studied for overlay wireless networks to optimize connection-level QoS. The contributions of our work are threefold. First, channel allocation scheme using both horizontal channel borrowing and vertical channel borrowing is presented and analyzed. When all the channels in a given cell are used, handoff requests(More)
