Background Since the high-rise buildings and deep underground structures dramatically increases in urban area, the decent design and construction of deep excavations is essential before these structures are actually built up. The building area is very susceptible to the changes of their geo-environment, and even minor insecurity of a deep excavation may lead to a catastrophic failure of structures...
High density wireless sensor networks (HDWSNs) are emerging as promising techniques in a variety of fields such as target detection and tracking, military surveillance, intelligent family, preventing forest fire loss, building monitoring and control, medical diagnostic, etc. HDWSNs composed of a large number of sensors with wireless communication, computation, information acquisition, and self-adaptation...
As the device size shrinks beyond 45nm technology node, logic BEOL (back end of line) started adopting Cu/Ultra low k (ULK) to reduce RC delay. With the introduction of low k material, IMD TDDB is notably degraded as numerous publications reported. The impact of ULK material deposition process, barrier layer deposition process on TDDB performance were investigated and discussed in-depth in this paper...
The advance of micro-sensor, nano-systems and networking technologies shown a great potential of small-size, low energy consumption, low storage, and self-adaptation sensors. Large scale wireless sensor networks (LSWSNs) consists of some them that have sensing, computation, wireless communication, and free-infrastructure abilities. The target signal selection problem in LSWSNs attracts attention of...
Malicious code detection based on behaviors is the development direction of anti-virus techniques. However, the current detection methods based on this theory expose several problems such as the unclearness of behavior sequence analysis and the high false negatives. For this situation, this paper proposes a malicious code detection method based on least-squares estimation. In this method, it correlates...
This paper describes the power earth-line monitoring system for the planning, design and implementation process. The system operates based on B / S mode and includes three parts: intelligent ground monitor, remote observation points and monitoring center system. Ground state data of the power lines are collected by the monitor, and then the data are transmitted to monitoring platform through the GSM...
The method of frame difference is a commonly used way for moving targets detection because it is simple to compute and easy to realize, but it has defects. The moving object captured will present a “double image” phenomenon, so it is difficult to extract goal accurately. This article proposes three image difference algorithm to capture moving target, which, with statistics and curve fitting method,...
