Autonomous parking has become the research focus. Fuzzy controller was ofen used to solve the nonlinear and time-varying problem of the autonomous parking. According to the shortcomings of traditional fuzzy controller, a new ant colony algorithm based on idle ant…

Multi-wall carbon nanotubes (MWNTs) film-based sensor on the substrate of printed circuit board (PCB) with interdigital electrodes (IDE) were fabricated using layer-by-layer self-assembly, and the electrical properties of MWNTs film sensor were investigated through establishing models involved with number of…

Welding robot has played an extremely important role in the welding production of high-quality, high-efficiency. The paper designed the hardware structure and software of spot welding robot. The hardware design mainly includes the major modules of arm and base; the…

In this paper, DEA model and AHP model combined with a new method to evaluate the performance of the small and medium enterprises. In this paper, mainly introduced the analytic hierarchy process（AHP）and data envelopment analysis ( DEA ), based on the existing on the small and medium-sized enterprise performance evaluation methods are analyzed, finally, through empirical analysis that the method of DEA based on AHP and has good applicability and feasibility. 

A new method of tracking the near space hypersonic vehicle is put forward. According to hypersonic vehicles’ characteristics, we improved current statistical model through online identification of the maneuvering frequency. A Monte Carlo simulation is used to analyze the performance…
