基于定位辅助按需拓扑维护的超宽带自组网路由算法

提出了一种基于定位辅助按需拓扑维护的超宽带自组网路由算法,该算法利用超宽带技术精确定位信息所获得的网络拓扑信息和路由信息进行分组转发,路由维护阶段在定位信息辅助下采用按需方式进行断链路由的修复和拓扑维护,通过基于位置信息的按需路由发现和限制路由查找范围,以及定位信息和网络拓扑信息的及时更新,在降低协议开销的同时保证了算法的有效性。仿真表明,该算法在分组丢失率、平均端到端时延和路由附加开销等方面具有良好性能,其优良的分布式控制特征能适应超宽带自组网的动态环境。     

Benchmark Analysis: Shopping with Proper Confidence

We discuss the issue of using benchmark doses for quantifying (excess) risk associated with exposure to environmental hazards. The paradigm of low-dose risk estimation in dose-response modeling is used as the primary application scenario. Emphasis is placed on making simultaneous inferences on benchmark doses when data are in the form of proportions, although the concepts translate easily to other forms of outcome data.     

关于完善我国仲裁法律体系的若干思考

我国民事诉讼法和合同法是仲裁法的重要渊源 ,完善仲裁法律体系 ,不仅需要对仲裁法本身进行修改和完善 ,而且还应对民事诉讼法和合同法进行修改和完善     

浅议美国证券仲裁制度的特征

美国证券仲裁现已成为解决证券争议的一种重要机制。它与一般商事仲裁相比,具有仲裁事项的限定性、法律基础的强行性、仲裁庭的组成专业性、仲裁运行机制的公益性、仲裁程序变迁的类诉性等特征。     

关于移动自组网自安全证书管理模型

论“和谐”对仲裁制度价值目标的建构

建立和谐社会的价值目标,既解读继承历史,又立足创新社会,和谐的内在要求导向着仲裁制度的完善,和谐的价值目标奠定了仲裁的发展方向,是仲裁制度为之实现的终极目标;仲裁制度的固有属性也暗合了和谐的建构目的,并成为和谐社会目标下处理纷争的重要制度。     

Minimum power assignment in wireless ad hoc networks with spanner property

Power assignment for wireless ad hoc networks is to assign a power for each wireless node such that the induced communication graph has some required properties. Recently research efforts have focused on finding the minimum power assignment to guarantee the connectivity or fault-tolerance of the network. In this paper, we study a new problem of finding the power assignment such that the induced communication graph is a spanner for the original communication graph when all nodes have the maximum power. Here, a spanner means that the length of the shortest path in the induced communication graph is at most a constant times of the length of the shortest path in the original communication graph. Polynomial time algorithm is given to minimize the maximum assigned power with spanner property. The algorithm also works for any other property that can be tested in polynomial time and is monotone. We then give a polynomial time approximation method to minimize the total transmission radius of all nodes. Finally, we propose two heuristics and conduct extensive simulations to study their performance when we aim to minimize the total assigned power of all nodes.

Energy conservation through resource-aware movement in heterogeneous mobile ad hoc networks

Energy conservation in mobile ad hoc networks is of paramount importance because most mobile nodes usually have very limited energy supply. Previous research on this issue focused on the design at the network or MAC or physical layer. In this paper, we study this problem from the new perspective of node mobility, i.e., analyzing the impact of node movement on energy conservation. In particular, armed with the inherent resource heterogeneity in mobile ad hoc networks, we propose a novel resource-aware movement strategy to make better use of some powerful nodes to achieve energy conservation. We also formulate the resource-aware movement as a NP-complete distance-constrained least-cost (DCLC) routing problem and propose an efficient heuristic solution. Extensive simulations have been used to demonstrate the effectiveness of the proposed schemes.     

论仲调结合在“一带一路”商事纠纷解决中的运用

根据“一带一路”商事纠纷的显著特征,其解纷机制应满足形式灵活多元、合意性较强、跨国执行便利、专业水平高等需求。仲调结合作为一种复合型纠纷解决方式,与诉讼、商事仲裁、商事调解相比所具有的优势更能满足以上需求。目前,仲调结合主要存在“先调解后仲裁”与“先仲裁后调解”两种实践模式。为了优化仲调结合在“一带一路”商事纠纷解决中的运用,应丰富仲调结合形式与设置具体操作规则,加强仲调结合组织建设与解纷人才培育,充分赋予当事人选择权以克服程序质疑,健全错误仲调结合结果的救济机制,订立多边条约与承认互惠关系以优化跨国执行等。
