Toward Integrated and Automated Management of Government Affairs
Changyu Liu,Juntao Xiong,Bin Lu 보안공학연구지원센터 2016 International Journal of Hybrid Information Techno Vol.9 No.1
An efficient government office automation system, which contributes significantly to social supervision, administrative efficiency, administrative quality, and service capacity, has been an important criterion for assessing the development of a country. With the rapid development of the global economy, more and more such systems are designed and implemented. However, few of them could take into unified account ever changing requirements of government affairs. In this paper, we develop an integrated and automated management system for government affairs. In the beginning, we analyze why we need the new system by introducing the overall background of the electronic governments and the office automation system. Then, according to system requirements, we divide the system into four functional modules, i.e., the login module, the approval flow module, the document management module, and the system management module. After that, we present many details about the architecture, the modules, and the database for the system design. Finally, illustrating both processes and interfaces of required modules, we implement the system based on the well known three-tier B/S architecture.

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.
Generic Information System for Chain Stores based on Borland C++ Builder
Changyu Liu,Juntao Xiong,Bin Lu 보안공학연구지원센터 2015 International Journal of Smart Home Vol.9 No.11
With the rapid growth of global economy, chain stores are springing up all over the world and have dominated more and more service markets, e.g., retail and dining. Accordingly, chain businesses have been one of the fastest growing industries since the beginning of this century. However, there are many bottlenecks for further producing competitive advantages of chain businesses, such as relatively small scales of chain stores, rather weak information awareness of managers, incompetent staffs and diversified business processes of chain stores, by using the traditional manual management. The introduction of chain store information systems, which integrate usually comprehensive information technologies, could provide managers of chain stores with a decision making yet overall management platform. In this paper, we develop a generic yet efficient information system for chain stores using MIDAS based three-tier client-server architecture. Besides, we also illustrate the system from three most principal stages in software engineering, which are system analysis, system design and system implementation.
A Parameter Selection Model for Avascular Tumor Growth
Changyu Liu,Bin Lu,Cong Li 보안공학연구지원센터 2014 International Journal of Control and Automation Vol.7 No.12
Based on a set of reaction-diffusion equations of oxygen, glucose and growth inhibitory factor which were built to describe the tumor growth environment, a cell cycle control factor was proposed for the simulation of the avascular tumor growth. In order to fix the model parameters, a two-level heuristic searching was given for the parameter selection. Finally, a total finite element energy equation was present to combine the chemical simulation and the physical simulation for the avascular tumor growth. Experimental results showed that the presented approach outperformed the baseline approach in the simulation of the mouse mammary tumor cells EMT6/Ro.
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.
A Hybrid Simulation System for Juicing and Filling Production Line
Changyu Liu,Bin Lu,Cong Li 보안공학연구지원센터 2014 International Journal of Smart Home Vol.8 No.6
As one kind of high quantity standardized commodities, the fruit juice product is an essential part to our daily life and overall economy. Therefore, it is necessary and important to design an efficient juicing and filling production line. According to deficiencies of traditional design methods, we propose a new design method by introducing virtual design technologies to develop a hybrid simulation system for juicing and filling production line, based on modeling software SolidWorks, virtual reality software EON Studio and application development software C++ Builder. We also describe our design method from aspects of process design and layout design, scene modeling, model import and route configuration, and interactive simulation control. Besides, we compare our design method with one traditional design method. Results show that our method can not only shorten effectively the design period but also improve greatly the design quality of the juicing and filling production line.
