Investigations into a device that separates one input signal into two signals of equal power, namely 3dB power divider, were carried out. This paper presents 3dB power divider using double layer metal slotted structure without any dielectric plate. The proposed structure with low coupling effect operates at 54GHz and has a 2GHz bandwidth. All the operating principles and simulation characteristics...
This paper presents a GPU-based stereo matching system with good performance in both accuracy and speed. The matching cost volume is initialized with an AD-Census measure, aggregated in dynamic cross-based regions, and updated in a scanline optimization framework to produce the disparity results. Various errors in the disparity results are effectively handled in a multi-step refinement process. Each...
Considering numerous of credible problems takes place in the distributed, loosely coupled, flexible and dynamic Web service environment because many factors, such as service provider, service user and service quality and so on, is uncertain, which all these problems exited lead the normal running of system to face serious threats. Therefore, this article, through processing the user feedback information...
Alternating current contactor is one of the important elements widely used in the automatic control system. So its reliability level is very important. This paper mainly concerns failure analysis of the failure contactors after the reliability trial of AC contactor. Firstly, the test device and the test parameters are introduced in brief. Secondly, test plan is given. According to the test plan, sixteen...
Over-load relay is widely used for electrical motor protection. Its reliability is becoming more and more important. This paper studies the reliability test method of over-load relay. According to the operation and failure modes of over-load relay, the protective success ratio is adopted as a reliability characteristic value. Based on the reliability estimation method and the sampling theory, the...
