The status of vehicle fault diagnosis protocols applied in the market is analyzed, and also are the problems of the hand-held diagnosis instruments. Through the way of combination of PC-style diagnosis software and Vehicle Communication Interface (VCI), the popular type of vehicle fault diagnosis system based on both K-line and Controller Area Network (CAN) is developed. The diagnosis system is divided...
This paper presents a fully functional and highly portable mini Unmanned Aerial Vehicle (UAV) system, HAWK, for conducting aerial localization. HAWK is a programmable mini helicopter - Draganflyer X6 - armed with a wireless sniffer - Nokia N900. We developed custom PI-Control laws to implement a robust waypoint algorithm for the mini helicopter to fly a planned route. A Moore space filling curve is...

The software framework, the main function modules and development methods are introduced. Result shows: the software has functions of design calculation, strength check, scheme optimization,...
Range anxiety — the fear of running out of battery power while on the road — is one of the major barriers to large scale adoption of Electric Vehicles (EVs). Range prediction solutions are available to address anxiety but most of them have limited functionalities. In this paper we propose a new, “Accurate Range” and “Energy-efficient Route” (ARER) selection mobile software solution which is based...
The petascale supercomputer Tianhe-1A, which features hybrid multicore CPU and GPU computing, achieves an optimized balance of computation and communication capabilities through a proprietary high-bandwidth, low-latency interconnect fabric. The authors' message-passing service, based on scalable user-level communication and offloaded operations for large-scale, low-latency collective communication,...
Due to the universal uncertainty in software reliability, this paper presents a novel approach to modification of the famous Jelinski-Moranda model based on cloud model. Finally, the methodology is exemplified with a famous software reliability data set.
There are many kinds of uncertainties inherent in software reliability. This paper presents a new approach to modification of the exponential function model based on cloud model theory. Finally, we show the practical application of the novel method by using a group of incomplete software failure data.
In cloud computing environment, it is common for a multi-component application to be deployed into the IT infrastructure on demand. Although the Application Component Placement Problem or ACP has been studied both in the academy and industry for some years, so far these approaches all rely on a centralized node to collect the information about the network topology and hosts of the targeting environment...
As ship power system continues to expand the scale, the workload of the calculation and analysis is growing. Using computer technology to create an object-oriented ship power system simulation platform will play an important role on the overall power system design and performance evaluation. In this paper, we add simulation application algorithm further based on the established graphical simulation...
Power and ground planes are the major noise sources in the electronic package and multi-layered printed circuit boards. We propose a novel imaging method to simulate the impedance of power and ground planes. In the proposed method, the noise propagation between the power and ground planes is equivalent to a two-dimensional transverse magnetic problem. The electromagnetic wave multi reflections from...
Based on the Muncy-Vitell Consumer Ethics Scale (CES), this study develops a Chinese version of CES. Three dimensions are added, they are (1) consumer hegemony, (2) uncivil or discourteous acts in public and (3) drawing upon public funds or resources for personal consumption. The study also compares the present scale with the previous ones. Results show that 'passively benefiting acts' were considered...
The definition and principle of Permanent Magnetism Linear Synchronous Motors(PMLSM) are given and the control strategy called model-free is introduced. The model-free control strategy has been compared with current control strategies such as the classic control PID control algorithm. The model-free and PID control will be applied on the linear motors based on cSPACE control system to prove the validity...
In the pumping station operation scheduling process, given the net head and flow of pump station, distribute the flow of the pumping station in pump of the pump station, to determine the best combination of the level of speed and the synchronous or asynchronous motor and the optimal pump flow or vane angle, thus make the operational costs of the pumping station to be minimum. To meet these requirements,...
This virtual instrument technology and laser Doppler velocity measuring instrument applied on instantaneous velocity test system of automatic mechanism driving component, have designed hardware of measurement system, through the analysis of movement of the automatic mechanism, and virtual instrument Labwindows/CVI was adopted, aiming at signal character, to design software of data acquisition and...
User Interface has a rapid development along with high-tech intervention, and the status of it is more and more obvious with its sensory beauty, formal beauty and technological beauty which draws the eyeballs of people, at the same time, the information of product has been transferred and exchanged among us during the communication process. Besides that, UI design also should follow the principle...
The GIS college education system covers a wide range of knowledge. It requires high standards of technologies to support it. Colleges and their students have both been greatly challenged in the process of teaching and learning. The main purpose of the GIS college education is to bring up professional engineers who can meet the demands of the society. Through analyzing the GIS college educational system...
AnyLogic is a kind of excellent software of complex system simulation. It can more accurately reflect the information of real life and expand the application of complex system simulation by adding GIS map as agent's environment. But, there are some problems at present when importing GIS data to AnyLogic. Based on the analysis of differences between ordinary engineering drawing and GIS vector diagram,...
