The motor is considered as the carrier and driving the precision control of rotation speed of the fuze, which is an effectiveway to simulate the centrifugal environment of the realistic simulation fuze. In order to precisely control the rotation speed of fuze, motor is used as the research object, a...

This article takes the non-bearing wall cast-in-place process as the research object, making comprehensive use of CFD analysis methods, CAE technology, ANSYS Gambit and Fluent software. the flow field simulation was carried out in the mixing section and the grouting process in the pouring wall process....

The train schedule is the basis of operation organization in urban rail transit. According to the properties of the full- length & short- turn routing mode in urban railway transit, a multi- objective nonlinear mixed integer programming optimization model of train shedule for a single transit line is...

This paper analyzes the risk factors of developing logistics finance business in railway enterprises, identifies the risks from two aspects of external risk and internal risk, and constructs the evaluation index system of railway logistics financial risk. Based on the analysis of BP neural network structure,...

In order to improve the operation safety of road tunnels, a new evaluation method of safety evaluation was proposed. Firstly, the index system was established by comprehensive considering all kinds of traffic safety attribute, including road engineering, traffic safety facility, traffic flow condition...

The Salar nationality believes in Islam, and the clansmen mainly live in Xunhua Salar Autonomous County of Qinghai Province and Dahejia, Baoan nationality and Dongxiang Salar Autonomous County, Jishishan, Gansu Province. The construction of many traditional settlements of the Salar nationality is ingenious...

The docking technology of the subsea production system control module (SCM) is a key part of installation. If the docking accuracy is not reached, or poor stability when docking, the butt joint between the hydraulic joint and the electrical joint cannot be accomplished, may also make the subsea control...

The convergence of estimators, e.g., maximum likelihood estimators, for increasing sample size is well understood in many cases. However, even when the rate of convergence of the estimator is known, practical application is hampered by the fact, that the estimator cannot always be obtained at tenable...

The significant jump in world crude oil price over the past year has raised great concern over the economic impact that such a price shock may bring about on Taiwan’s economy, which has been characterized by extremely high import-oil dependence. Previous analyses have been tackling similar issue from...

In 2005, Sun, Hsieh, and Hwang proposed two secure e-mail protocols with perfect forward secrecy. In the first protocol, the authors apply smart card and Diffie-Hellman key agreement scheme to achieve the perfect forward secrecy. However, due to it requires a smart card to store some parameters, it is...

The feature selection process can be considered a problem of global combinatorial optimization in machine learning, which reduces the number of features, removes irrelevant, noisy and redundant data, and results in acceptable classification accuracy. In this paper, we propose a combination of genetic...

A novel training paradigm for artificial neural networks had been developed and presented in this article. In the proposed approach, a revised version of particle swarm optimization (PSO) had been employed to find out the optimal connection weights of feed-forward artificial neural networks for given...

In order to be competitive in the semiconductor manufacturing industry, quality improvement and yield enhancement have received increasing attention. The research focuses on the molding process of Integrated Circuit (IC) assembly. The defects often occurred in molding process include hole, vein, crack,...

This paper presents a novel approach to natural scene segmentation. It uses both color and texture features in cooperation to provide comprehensive knowledge about every pixel in the image. A novel scheme for the collection of training samples, based on homogeneity, is proposed. Natural scene segmentation...

The purpose of this research is to use the visual inspection technique for the automatic tool wear measurement of different coated drills. The tool wear images with the different coated drilling are captured using a machine vision system incorporating with an effective vertex detection algorithm based...

Mobile agents (MA) needs to migrate to several host to accomplish its task .Migration strategy is responsible for planning out an optimal migration path ,which ensures mobile agent to complete its task correctly and efficiently at the minimum cost .This paper describe the strategy adopted by a mobile...

In nowadays business, online service in Internet Banking is a major concern for managing customer relationship but on the other side, there are several challenges that should be faced by banks when they implement this technology. By using the technology acceptance model, this research was conducted through...
