As one of automotive engine's important working states, idle-speed has much relation to the engine's fuel consumption and exhaust-gas pollution level. Effective idle speed control (ISC) can improve fuel economy and reduce exhaust emissions, the principal operation of ISC is to uphold the actual engine speed very close to the set point value when any disturbance is added. Automotive engines are typical...
Analyzing the system of several Chinese word segmentation algorithms for the current existing problems, we design and construct a new dictionary mechanism. We present a segmentation algorithm, forward maximum matching method that adding 1 word each time and self-define the IDC function as disambiguation algorithm to achieve a relatively complete system of experimental Chinese word segmentation. By...
Through-mask electroplating has been widely used in the fabrication of chips, BGA substrates and PCBs etc. The uniformity of plating thin-film is the major factor contributed to the reliability of the products. Currently, it is usually by setting optimum plating parameters and adopting electrochemical method to achieve the uniformity of plating. However, the problem of non-uniform distribution of...
A model, including segregation from silicon melt to silicon crystal as well as evaporation from silicon melt to Ar atmosphere, was established for simulating the oxygen distribution in multicrystalline silicon (mc-si) ingot, which shows good agreement with the experimental results. According to this model, the oxygen distribution in the bottom of ingot is mainly determined by the evaporation of oxygen,...
This paper investigates communication protocols used to implement the network-103 substation communication protocol, which is generally applied in China, simulates a representative substation communication system, and presents an experimental comparison of different transport protocols used to transmit network-103 traffic. Simulation studies in the article make use of the EPOCHS (Electric Power and...
