With the increasing utilization of electric vehicles (EVs), transportation systems and electrical power systems are becoming increasingly coupled. However, the interaction between these two kinds of systems are not well captured, especially from the perspective of transportation systems. This paper studies the reliability of integrated transportation and electrical power system (ITES). A bidirectional...
Motion control system is the core component of high density packaging equipment, the characteristics of its movement performance directly determines the performance and quality of the high density packaging equipment. Based on this, this paper presents a method to enhance the dynamic performance and setting performance of motion control system by means of fine tuning for the movement parameters of...
As one of challenges, clip design for bonding area is becoming smaller and smaller to achieve die size requirement, better view inspection and efficient solder flux cleaning. However, with a small bonding area, there will be a concern on high thermal resistance during working condition, especially under a surge current, in which junction temperature may be higher than the melting temperature of soft...
Based on analyzing the situation of current underwater navigation, this paper presents an independent underwater navigation method, namely the terrain matching algorithm based on contour image. Firstly, according to multibeam bathymetric system data, the topographic contours are extracted out from the data and then form contour image. Secondly, the contour used for image matching is coded. The coding...
Based on the current situation of underwater navigation, this paper presents an underwater topographic matching navigation method which is the integration of TERCOM and MCTM algorithm. First of all, we use the TERCOM to acquire a rough position of vehicle. Secondly, a search area is found according to TERCOM positioning result. The multi-contour matching algorithm is implemented in the area. The algorithm...
With the rapid development of the field of industrial process control and the fast popularization of embedded ARM processor, it has been a trend that ARM processor can substitute the single-chip to realize data acquisition and control. A new kind of remote I/O data acquisition system based on embedded ARM platform has been researched and developed in this paper, whose hardware platform use 32-bit...
Due to its remarkable properties, carbon nanotube (CNT) was widely used in different areas, especially in electronic packaging for the improvement of the adhesion and thermal conductivity. CNT as an emerging thermal interface material (TIM) is now widely used to improve thermal dissipation in electronic packaging. CNT array as TIM is suffering from poor adhesion between CNTs and substrate in packages...
