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.

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.

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.

Born-digital cultural heritage faces the challenge of vanishing away rapidly. In this paper, the issues surrounding the preservation of born-digital cultural heritage are described and explored, and preservation strategies for born-digital cultural heritage are recommended based on the UNESCO's Charter for the Preservation of Digital Heritage. The authors believe that a major focus of digital preservation efforts should be the preservation of born-digital heritage materials.

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.

The poverty and environmental degradation are very serious in karst regions of southwest China. In this paper, the spatial distributions and variations of oxygen regulation values (ORVs) were evaluated for the typical karst areas in Northwest Guangxi, China from 1985 to 2005, based on remote sensing and geographic information system techniques. The results showed that ORVs decreased firstly and then increased. ORVs were 9170 million Yuan in 1985, 5831 million Yuan in 1990, 7802 million Yuan in 2000 and 8793 million Yuan in 2005, respectively. Woodland and shrub were the two largest contributors to total ORVs (70.51% in 1985, 69.13% in 1990, 73.35% in 2000 and 66.23% in 2005). ORVs declined from west to east, and in creased from 4338 million Yuan in 1985 to 4780 million Yuan in 2005 in the typical karst areas. This indicates that ecosystem conditions are improving because of the application of rocky desertification control policies.

This paper presents a novel tutoring system. A multi-agent system architecture offers a promising framework for dynamically managing teaching agents in a distributed environment which uses computational approach to producing 3D images for Computational Intelligence (CI) course teaching. One teaching example is introduced for showing the advantage of the system. It uses complex function expressions as genetic coding to form a binary tree, and all genetic operations are performed on the binary tree. Corresponding complex functions are processed by software MATLAB to form 3D images. From this example, students can learn the tree based genetic algorithm and its application in 3D images generation easily.

Based on system dynamics theory and multi-agent technology, this paper creates an evaluation model of educational environment. Firstly we create student model and environment model with formal language, and then we discuss factors in educational environment and their relations and get some formulas to calculate education status of a student. At the end of this paper, we give the simulation results. The results show that the model has the ability to simulate the rules and laws of real educational environment. And the research has an important practical significance to improve the quality of education and adjust the national education policy.

Topic map is one of the hottest areas in information retrieval field in that it enables a user to navigate and access the documents he needs in an organized manner, rather than browsing through hyperlinks that are generally unstructured and often misleading. This paper proposes a new framework for information retrieval. Through actions of registry, discovery and access in grid information service discovery process, a grid space manager will find out the suitable services. And grid agent should remember the success and quality of the former cases by knowledge element mining and topic map building and reasoning, therefore the agent can gain experience of user's preference. We also detail the methods through which we can mine knowledge elements from web page resources' and to build extended topic maps including a new knowledge elements level.
