HIRFL system is the most advanced all-around heavy ion research facility. It is responsible for many of the scientific tasks in China, so to ensure its safe operation is a major responsibility by the Institute of Modern Physics, Chinese Academy of Science. There are many magnets and power needs water to cool, so the water system plays an important role in the whole HIRFL system. We design a set of...
The popularity and accessibility of Sina Microblog have attracted a large number of spammers to conduct spamming behaviors. They can spread advertisements, disseminate pornography, virus and expose phishing. All of these behaviors are extremely harmful to legitimate users. It is necessary to detect spammers from legitimate users in Sina Microblog. In this paper, we defined two kinds of spammers, advertising...
Recently, Slideshow presentations such as research talking, demonstrations and lectures are performed heavily. On the other hand, handwriting ones are rarely performed. However, handwriting still have advantages and slideshow also have limitations. In this paper, we investigated merits and demerits of slideshow and handwriting lectures and proposed new oral presentation method that has both merits...
The channel capacity reflects the amount of information the channel can transmit. In particular environment, a specified link with maximum capacity is needed in order to satisfy the transmission requirements. In this paper, we propose a novel capacity maximization and spectrum allocation joint algorithm on specified link in a novel self-organized network model. First we construct an improved threshold...
This article introduces status and prospects of current embedded systems industry as well as its professional personnel education status and existing problems in universities and colleges in China, presents embedded systems professionals demand and ability and quality constitutions from enterprises' points of view, introduces the course systems and practice arrangements for embedded systems-majored...
Data mining has been gaining popularity in the knowledge discovery field, particularity with the increasing availability of digital documents in various languages from all around the world. Several data mining methods which applied in intrusion detection systems are introduced. And an agent-based network intrusion detection system using data mining approaches is presented. The proposed system is constructed...
The embedded systems have received increasing research interest in recent years due to its wide usage. This paper presents system on programmable chip (SOPC), a new technology in the embedded systems, to support the development of design projects for undergraduate students in their electrical and computer engineering curriculum. FPGA-based SOPC development board with reduced instruction set computer...
ldquoCollege Fundamentals of computerrdquo is a compulsive subject of students in the non-computer majors of college and universities. In this paper, it analyzes the status of the college computer public course in the request of quality-oriented education. And find several practical and feasible teaching methods.
This letter presents a universally valid algorithm designed for homogenizing chaos-based pseudo-random number generators (PRNGs). The algorithm bases on shifting-bit operations represented by floating-point numbers on computers, without aiming at material chaotic systems. Set Logistic map, Henon map and Lorenz system as examples to test the algorithm, respectively, showing that it is viable. We can...
