Capacitive energy storage have been widely used in area of pulsed power, however, it canpsilat be used in application which requires long time energy storage (for example, accumulation of solar energy) due to its electric leakage. Since the superconducting inductor has great carrying capacity and zero DC resistance, it can store energy with no loss over a long period of time. In addition, it only...
The wireless sensor network is a highlight of information technology, which integrates sensing, computation and communication together, and it can be widely utilized in various fields. This paper proposes an acoustic localization system based on wireless sensor network and the factors affecting the precision of time synchronization are analyzed. Reference broadcast synchronization (RBS) is implemented...
This paper presents a new metric to assess the performance of the image fusion algorithm. The proposed metric is based on image phase congruency, which provides an absolute measurement of image feature with a numeric value ranging from zero to one. By comparing the local cross-correlation of corresponding phase congruence maps of input images and fusion output, the quality of the fused result is assessable...
How to enable a robot to explore in an unknown environment containing obstacles via local sensing is an important research issue for robot navigation, map building, and localization. In this paper, a reactive and visibility-based exploration algorithm is proposed. By line-of-sight sensors, the robot can find the occlusion points between covered and uncovered regions, and then approach these occlusion...
User requirements of multimedia authentication are various. In some cases, the user requires an authentication system to monitor a set of specific areas with respective sensitivity while neglecting other modification. Most current existing fragile watermarking schemes are mixed systems, which can not satisfy accurate user requirements. Therefore, in this paper we designed a sensor-based multimedia...
