Watchdog technique is a fundamental building block to many trust systems that are designed for securing wireless sensor networks (WSNs). Unfortunately, this kind of technique consumes much energy and hence largely limits the lifespan of WSN. Although the state-of-the-art studies have realized the importance of trust systems’ efficiency in WSNs and proposed several preliminary solutions, they have...
With the development of computer network and widely used of Internet, online information increases in broadband level exponentially, the difficulty and complexity of information retrieval also increase gradually, so the Crawler is developing rapidly. Crawler is a program that can auto collect information from internet. In this paper, we design and implement a multi-thread Crawler for specific resources...
This paper presents a design scheme of blood pressure(BP) measurement for health care based on the oscillometric method. Maximum curvature method is proposed to simplify algorithm of oscillation amplitudes extraction. According to the results of the simulator data, on the premise of accuracy assurance, this approximate method not only reduces the complexity of detection algorithm effectively, but...
Perspective deformation is one of the main issues needed to be addressed in real-scene character recognition. An effective recognition approach, which is able to handle severe perspective deformation, is to employ cross ratio spectrum and dynamic time warping techniques. However, this solution suffers from a time complexity of O(n4). In this paper, a clustering based indexing method is proposed to...
