Understanding the behaviors of a software system is very important for performing daily system maintenance tasks. In practice, one way to gain knowledge about the runtime behavior of a system is to manually analyze system logs collected during the system executions. With the increasing scale and complexity of software systems, it has become challenging for system operators to manually analyze system...
Location information is of paramount importance for wireless Sensor Networks (WSNs). The design of WSNs has always been focused on an specific point of networks in a two-dimensional (2D) space. Nowadays this design is not enough and the study of the three dimension is needed. In this article, we focus on 3D location accuracy in WSNs. We quantify the estimation accuracy for the RSS measurements by...
The shortcomings about present genetic algorithm applying to classification are analyzed. Using the method of minimum propagating tree can cluster complex shape and non-overlap sample candidate solutions into races. The algorithm regulates optimization with "race" method and controls individuals in a micro way with race crossover. We also mixed crossover operator based on the thought of...
