A Micro-Payment Based Isolation of Misbehavior Secure Routing for Sensor Network

In this paper, we present a Micro-payment based Isolation of Misbehavior(MIM) secure routing protocol. The protocol contains three parts: micro-payment scheme, routing discovery and malicious nodes detection. The micro-payment scheme proposed in MIM is the first virtual currency system that can be suit for sensor network environment. Based on thc micro-payment scheme, we device an energy aware routing protocol, which forwards packets by auction. Furthermore, the base station can detect and isolate misbehave or non cooperate nodes according to the routing information.

Application of microfluidic chip to realize controllable pH gradient

A kind of PH gradient microfluidic chips through soft-lithography microfabrication for isoelectric focusing (IEF) and high performance liquid chromatography (HPLC) is introduced here. These pH gradient chips have the advantages such as easy fabrication, controllable pH range and precision, isoelectric focusing and separation at the same time, low voltage for isoelectric focusing, and time stable pH gradient. This method has potential application to sample preparation, separation and analysis of microfluidic chips.     

Original component of grain size index in core sediment from southwestern slope of the South China Sea and its paleoenvironmental implication

Traditional grain size analysis was basically used to discriminate sediment type based on its particle dimension for sedimentary naming[1,2] and to analyze the dynamic feature of transport medium, including water current and wind strength[3―5]. Recently, some patency advances havebeen made by using different methods to separate different grain sizes in various original composition from sediments for searching a new way of paleoenvironmental study[6―8]. Grain size analysis is even playing an …

基于敏感度探测的南京奥体中心控制网三类优化设计

三类优化主要是对控制网进行优化设计，在精度及可靠性允许的范围内删除一定数量的观测值来减少外业观测。结合已有的精度敏感度与可靠性敏感度提出综合敏感度的概念，探讨了三类优化的另一种方法，即应用敏感度探测最佳优化位置，最后通过南京奥体中心控制网观测数据计算比较三种方案，结果表明：采用可靠性敏感度优化控制网要比精度敏感度优化后的点位精度稍好；综合敏感度方案可达到与精度敏感度、可靠性敏感度方案相同优化效果。
