Improved fish migration optimization method to identify PEMFC parameters

In a worldwide environment context where the emergency need to decrease pollutant emissions is an important issue, the research for solutions is increasing. Fuel cell technology is anticipated to become a practicable approach for solving the problem of pollution due to its environmentally friendly characteristics. In this work, a novel problem formulation is suggested for the efficient recognition of PEMFC parameters which the solving is by using the Improved Fish Migration Optimizer (IFMO) technique. After coding the steps of the algorithm in MATLAB, the objective function is resolved for the fuel cell. Comprehensive simulations evaluate the formulation performance with the suggested and traditional objective functions; then, the outcomes are compared. To confirm the suggested formulation ascendancy compared to the traditional curve-fitting method, a complete assessment based on convergence rate, the value of the objective function, and the value of absolute voltage error are performed. The achieved value of the objective function, absolute voltage error, and average time of computation is 0.005, 0.4, and 1.63, respectively. Environmentally, the combustion of hydrogen and its use in PEMFC produce no carbon dioxide.     

我国白酒国际化道路的思考

根据统计数据分析,我国白酒市场已趋于饱和,开拓国际市场,走国际化道路是白酒发展的需要。白酒的国际化是一项庞大的系统工程,涉及到体制转轨、标准修订、人才培养和文化推广等多个领域和环节,单靠某个部门或企业散兵游勇式地单打独斗难有成效,必须从体制、市场、人才及技术标准等方面进行综合研究,认真分析,找准对策,才能真正走好白酒的国际化之路。     

Exploration on ecological regulation of the reservoirs

Reservoir regulation process in the Yangtze River Basin is mainly divided into two types of flood regulation and initiating benefit regulation. The present reservoir management system and operation mode are mainly fro dealing with or coordinating of flood control and benefit initiation as well as benefit distribution among various beneficial functions. From the view point of river eco-system protection, the current regulation mode has two kinds of problems: firstly, most of the reservoir regulation plans do not consider eco-system protection at downstream of dams and needs of environment protection in reservoir areas; secondly, integrated regulation or management of water resources is ignored. It is very necessary to improve reservoir regulation mode, bearing problems faced by regulation of the Three Gorges Reservoir and issues related to cascade development and regulation in Tuojiang and Minjiang River Basins in mind. In accordance with the concept of scientific development, and the philosophy of “ensuring a healthy Yangtze River and promoting the harmony between human and water”, taking flood control, benefit initiation and eco-system as a whole, this paper put forward the basic consideration to improve reservoir regulation as follows: on the basis of requirements of eco-system protection at downstream of dams and needs of environment protection in reservoir areas, we should bring the functions of reservoir such as flood control and benefit initiation into full play, control the negative influence to the eco-system at downstream of dams and the environment in reservoir areas in an endurable scope, and restore the eco-system and the environment step by step. This paper put forward the relevant regulation process aiming at the idiographic problems such as protection of eco-system at downstream of dams and environment in reservoir areas, protection of aquatic wildlife species and fish species, regulation of sediment and protection of wetland.     

基于综合代价因子的新型卫星网络路由改进算法

为了解决传统卫星网络路由算法难以从根本上避免链路切换及其引起的路由重置、分配控制等问题,在国外现有卫星网络路由算法的基础上进行改进,提出一种基于综合代价因子的新型路由算法 ICFRA。该路由算法利用相邻卫星在源节点和目的节点之间寻找一条最短传播路径,进行数据包的转发,经过 NS2软件仿真验证,该路由算法在网络容量、投递率、稳定性、时延、抗毁性等关键性能指标方面均优于现有算法,对未来的卫星通信路由算法设计有一定的参考价值。
