With the global environmental changing and energy scarcity, human pay attention to the living conditions. Automobiles, consuming energy and emitting harmful substance, become the focus of attention. In order to control the emission of the harmful substance in a certain range, different new regulations were formulated to limit the emission pollutants of automobiles. It was a new facing challenge that...
Increasing power output performance, decreasing fuel consumptions and reducing emission pollutions have become the direction and object of the motor development now. In order to achieve the object, the engineers have taken various measures. Among them, Turbo charging technology was the better improving method. Now several new turbocharger systems are used in gasoline engine-VTG in Porsche car, TSI...
Software testing is the important means that guarantee software quality and reliability. Improving the automation ability of software testing is very important for ensuring software's quality and reducing development cost, and improving the automation ability of test cases generation is the key point for the entire process. This paper discusses the methods and techniques of genetic algorithm as the...
In real-time OS, one of the most primary factor that affecting real-time performance directly is scheduling strategy. μC/OS-II, which adopting a single static priority scheduling manner, could not be well-suitable for complex hybrid tasks set scheduling. Based on EDF (Earliest Deadline First) algorithm, in combination with task importance consideration, a new dynamic scheduling algorithm EDIF (Earliest...
Green Logistics is the main trend of the modern Logistics. Implementing the circumstantiation in logistic processes can make the best use of logistics resources and then boost the development of circular economy. Concentrated use of resources, green storage, green transportation, green packing, green distribution processing, green loading and unloading, green information gathering and management,...
It can't provide methods to find out the suitable memory block to allocate in the original uC/OS-II's DSA. In order to improve the memory utilization and reduce memory fragmentation of uC/OS-II, this paper analyses, adopts and designs Lazy_Buddy in uC/OS-II, according to the embedded system's requirement of fast response time, reliability, high efficiency. Experiment datas are presented, and the result...
With the rapid development of embedded technology, embedded devices have been widely integrated into people's work and life. In order to improve the efficiency of interaction with embedded devices, research on embedded GUI for exchanging information with users has become a focus of study. This paper introduces the Linux 2.4 kernel based driver of s3c2410 touch-screen and the working mechanism of Qt/Embedded...
This paper discusses the key techniques in the design and implementation of a fingerprint authentication system and provides a good solution to perform identity authentication for enterprises. In the design, ASP.NET is adopted to build an overall framework of the system. In the framework, ActiveX, SQL Server together with Java programming language are used to construct a complete fingerprint authentication...
This paper presents a fuzzy sliding mode controller for the Buck converter by a novel method, the novel method considers system and designs the controller on the three-dimensional space, and thinks over the dynamic information of all elements in the buck circuit adequately. At the same time, the method adopts the exponent tendency arithmetic to descend chatter, and employs fuzzy theory to improve...
