A novel State of Charge (SOC) estimation algorithm in Battery management system (BMS) needs to be simulated and tested abundantly before application. Therefore, in this paper, a hardware-in-loop (HIL) platform based on xPC target is built to simulate and test the SOC estimation algorithms. Firstly, we design a data acquisition system with a hardware filter. Secondly, a first-order RC network equivalent...
Web-based language learning (WBLL) environment has provided English education a new arena where learning and teaching activities are vivified by the feats of computer and internet technology. A full development of learner autonomy can conduce to success in web-based English learning. This paper aims to find out ways to improve learner autonomy to achieve Chinese students' success in web-based English...
Along with the rapid development of peer-to-peer network technology and the fast increasing number of users, the problems of security in peer-to-peer network is becoming more and more important. By researching the previous trust model of peer-to-peer network, we propose a trust model(PTM) for peer-to-peer networks based on punish mechanism. Firstly, we use the method of social grouping nodes in the...
SQL Injection (SQLI) is an attack method that is easy to achieve but often leads data leak and malicious control of the system, so anti SQLI is very important for applications using database. This paper proposes an algorithm for detecting SQLI based on statements sequence digest (SSD). Abstract SQL statement, SSD and its calculating method are defined; algorithms for building SSD and detection SQLI...
This paper mainly addresses the commutativity issue discovered in iterated belief revisions under the framework of AGM. Namely, given an iterated formula K * x * y, under what condition K * x * y = K * (x Λ y) = K * y * x can hold needs to be reconsidered. As we shall demonstrate, AGM 7th and 8th postulates together falsely imply the commutativity existing in Rott's selection puzzle. On the other...
Combining with the usual requirement and multi-constraint conditions of examination arrangement, the math model of examination arrangement is built, and a sub-rule algorithm for arrangement of examination seat based on the proportion of examinee is proposed. Then the detail step of the algorithm is given, and the complexity is analyzed. The Analysis and experiment result show the algorithm can control...
The intelligent computer assisted instruction (ICAI) is now a hot topic of computer assisted instruction. One of the difficulties is how to judge static and dynamic behavior of students in order to adjust teaching strategies according to individual difference of students and to raise learning effect. In this paper, the structured student leaning model based on ICAI is put forward, so that teaching...
The outbreak of worm is very frequent today. It has great impact on the society infrastructure and people's wealth security. A large number of experts have devoted themselves to the research of worm propagation modeling. Both deterministic model and stochastic model have been used in modeling worm spread. In this paper, we analyze the worm functional structure, and then propose a deterministic worm...
A GA-based multilateral multi-issue automated negotiation model has been proposed. It dynamically estimates the opponentpsilas preference according to the change of the opponentpsilas offer in the process of negotiation and finally accelerates agents to reach an agreement. Experimental results show that agents can reach an agreement in a short time using this model, and the total utility of all agents...
