More and more attention is paid to computer aided automobile body conceptual design field in recent years. This paper presents a novel method which applies evolutionary design to the automobile body conceptual design system. By using some evolutionary design algorithm like genetic algorithm, the method helps designers to produce innovative design ideas and interesting results in the stage of automobile body conceptual design. The case study demonstrates the advantages of the proposed method.

The problem of content-based spam filtering on machine learning methods actually is a binary classification. SVMs can separate the data into two categories optimally so SVMs suit to spam filtering. With used into spam filtering, the standard support vector machine involves the minimization of the error function and the accuracy of the SVM is very high, but the degree of misclassification of legitimate emails is high. In order to solve that problem, this paper proposed a method of spam filtering based on weighted support vector machines. Experimental results show that the algorithm can enhance the filtering performance effectively.

QoS-oriented content delivery is an important component in en-learning systems. In this paper, we study the object placement problem in the parallel-access context for QoS-oriented content delivery. The problem is formulated in terms of bandwidth maximization and further proved to be equivalent to the Fault Tolerant Facility Location Problem (FTFL). In this problem the bandwidth that violates the triangle inequality is measured by a cost function which forms a metric when the shortest-path routing is deployed. Though there have been efficient UFL algorithms with good performance guarantees, the challenge of the FTFL Problem arises due to the conflict of its connectivity requirement (multiple distinct connections) and cost minimization (which leads to identical connections with the minimum cost). We investigate possible solutions for addressing this conflict after giving an overview of the existing techniques. Extension of the problem to the context of QoE-aware multimedia delivery which has important applications in e-learning systems is also discussed.

The article discusses the social issues in online education. When helping people to improve the learning environment, the Internet brings about lots of social issues, such as unfair access to education, cultural issues of the Internet in classrooms, un- adapted educational system, un-comprehensive development of learners, and loss of rights and so on. Several measures can be adopted for solving the social problems, including establishing the correct value orientation, intensifying the humanistic care of law, enhancing the humanistic care of ethic, and improving the learners' information literacy.

Nonlinear problems of fourth order appear in medical analysis. Most research focus on the existence of solutions by topological indices and critical point theory. Inspired by the effective randomized searching nature of PSO, this paper presents a new technique of optimizing fourth order nonlinear problems. We also give an example that satisfies the conditions of a previous result of CC Pang. Experiments are presented to show the effect of the algorithms.

In order to enhance the quality of teaching, the teaching evaluation has become a common way for strengthening the teaching management in a lot of colleges and universities in our country. However, the scientific nature and effectiveness in practice are constantly questioned mainly because the teaching evaluation is affected not only by the studying initiative, interest, and teaching environment but also by other factors, such as the teaching attitudes, teaching methods and the class contents. Compared with Donghua University and MIT, this paper revealed the difference of the design concept, the indicators and the purpose of teaching evaluation system between Chinese and foreign universities, which would further standardize this activity, and provide a new idea to improve our teaching evaluation system.

A dual smooth TCP congestion control algorithm based on AIMD (SAISD) is presented. SAISD uses a decreasing function as the incremental in the speed of sending, and when the congestion is detected, the current sending rate is changed smoothly refered the historical value of cwnd, thus the oscillatory of sending speed is improved. The simulation results show that when the UDP and TCP co-exist, SAISD provides a smooth services for UDP, and it has good fairness and stability, meanwhile it can improve the utilization of bandwidth.

In view of the paperless teaching and the test situation of programming curriculums, this paper employed the analytic hierarchy process (AHP) to construct achievement evaluation indicator system and the examination paper evaluation indicator system for programming curriculums group. This evaluation indicator system made full use of the wealth of information of the process of paperless teaching and examination. Finally an evaluation software system was formed based on this evaluation indicator system. This evaluation software system can be used as a basis of the teaching evaluation for the teaching management department as well as a method of analyzing student's study situation and teacher's teaching situation.
