Ideal Free Distribution in Two Patches

In this paper, the formats of Julia sets for a class of nonlinear complex dynamic systems with variable coefficients were studied under certain conditions. For the complex dynamic systems in piecewise cases, we proposed some methods to control the forms of their Julia sets and stable domains analytically. What’s more, we illustrated that our methods worked well by computational simulations. Our work provides a better understanding about how to control the Julia sets of certain complex dynamic systems.     

Deployment strategy for static chargers in WRSN

The traditional deployment strategy of static chargers in wireless rechargeable sensor networks (WRSN) covers all the area.The basic idea is to cover all the positions of nodes.A mathematical model of distance between a charger and the farthest node was established,the relationship between the number of nodes and the mathematical expectation of minimum radius of charging was analyzed,and deployment strategy for static chargers was proposed.The method based on the locations of all nodes that need to be charged in the area,used the smallest enclosing circle (SEC) algorithm and finds the optimal location of the charger through Euclidean delivery boy algorithm.It will decrease charging radius,reduce the minimum required transmitted power,thereby saving the average charging energy consumption.The experimental results demonstrated that the less the number locations that the nodes existed,the more energy will be saved.

Analysis of the Stakeholder Engagement in the Deployment of Renewables and Smart Grid Technologies

The implementation of higher shares of renewables in a global energy mix has to be accompanied by simultaneous deployment of enabling smart grid technologies (SGTs). This combination will inevitably lead to a revolutionary change in a conventional energy system, particularly, the shifting role of consumers to prosumers. But resistance may arise from such a dramatic shift, since it is associated with high uncertainty in conjunction with increasing responsibilities of all stakeholders, the urgent need of effective control, and the development of a process. To ensure the positive influence, coherent actions of all players, and appropriate treatment of the spots of resistance, the analysis of the interplay between key stakeholders has been done. The paper introduces the framework for stakeholders' analysis, applies it on the European Union (EU) example, and provides recommendations to reduce the resistance of SGTs deployment.     

基于广义对数函数的统一路由策略

通过对最短路径路由策略、有效路由策略、最小信息路径路由策略的算法以及广义对数函数进行研究发现：将广义对数函数内的变量进行部分修改可实现以上三种算法的统一,并且通过对此种统一算法进行改进并且仿真发现,在此统一算法变量连续变化的同时,某些路由策略在复杂网络中的表现同样具有连续性。这表明此种算法可以将以上三种路由策略进行完美的统一。

基于对象引用关系的Java程序内存行为分析方法

本文提出一种基于对象引用关系的Java程序内存行为分析方法.与传统的通过内存消耗的大小来确定程序中数据结构的重要性并分析相关内存行为的方法不同,本文方法同时考虑内存消耗和内存支配两个因素来确定一个数据结构在程序内存行为中的重要性,通过研究数据结构之间在内存使用上的支配关系和对数据结构进行引用分析,得到程序中重要的内存行为.实验结果表明该方法能有效地分析程序的内存行为,且对比其它方法能提供更加准确的内存行为分析结果.
