A Three-Tier Salary Management System for Higher Vocational Colleges
Bin Lu,Changyu Liu,Tiezhu Zhao 보안공학연구지원센터 2015 International Journal of Multimedia and Ubiquitous Vol.10 No.4
In this paper, we design and implement a three-tier salary management system for higher vocational colleges. At the beginning, we conduct an overview of the entire present situation of the salary management mechanism for the higher vocational colleges, and propose to improve the financial work efficiency of the higher vocational colleges by using ASP.NET based information management system. Then, we analyze the primary system requirements and divide the system into four functional modules, which are the salary management module, the system management module, the login module, and the query as well as report module. Next, for the system design, we present details about the use case design, the data process design, the business process design, the database design, and the design of architecture as well as modules. Last, we implement the system based on a three-tier architecture, which are the user presentation tier, the business logic tier and the data access tier.

Cleavage Furrow Formation for Avascular Tumor Growth based on Finite Element Modeling
Changyu Liu,Dapeng Li,Bin Lu,Tiezhu Zhao 보안공학연구지원센터 2015 International Journal of Multimedia and Ubiquitous Vol.10 No.3
A number of studies have shown that the prevention and cure of malignant tumors may become much easier if growth mechanisms, such as the role of cleavage furrow formation in tumor cell division, could be discovered and understood in the earlier avascular phase. Although it is well known that metazoan mitotic spindle which is one of the most important substances during the cytokinesis of a cell division determines the position of the cleavage furrow formation, we are still on the verge of solving the puzzle of what molecules and how they control the formation of the cleavage furrow. In this paper, we propose a cleavage furrow formation approach based on finite element method, which combines nodes selection, mesh partition and matrix assembly in a total energy equation, for modeling the mechanisms of avascular tumor growth. We also perform several experiments. Results show that, by using our proposed approach for the avascular tumor growth, the positions of cleavage furrows are decided not only chemically but also physically and tumor cells are not symmetric, which demonstrates the effectiveness of our proposed approach.

Both the rapid growth of global economy and the rapid improvement in living conditions have witnessed an explosive requirement of foods that are rich of vitamin. Juice beverage, as one kind of these foods, is very popular among people of all ages due to its higher portability and easier preservability. However, there are many issues, such as a very low device utilization rate, a very long design period and an inflexible manufacturing process, by using the traditional juicing and filling production line. The introduction of virtual reality simulation technologies can not only detect bottlenecks of the production line during design period, but also process fruits according to seasons for improving the total efficiency of one single production line. In this paper, we combine customizable configuration and interactive control to design and implement a simulation system of juicing and filling production line based on the traditional client-server architecture. Practical applications show that the developed simulation system can not only shorten effectively the design period but also improve greatly the design quality.
