Graduation Project is a significant step for undergraduate students to practice their knowledge learned in universities. Due to many reasons, e.g., there are no tools to support total quality control process for the entire graduation project management, the completion quality of graduation project is not as good as the authorities expected. To address this issue, we implemented a graduation project management information system based on B/S model by using ASP & SqlServer to monitor, manage and control those which participate in the graduation project processes. It is driven by total quality control method and is supported by workflow technology. This system has been deployed and used in our department for 6 years. By this system, the management of graduation project becomes easy and efficient and the completion quality of graduation project as well as the graduation paper is improved a lot in our department. © 2010 IEEE.

A locking mechanism for distributed database systems

Journal of Networks 2014年第8期9卷 2211-2217页

To overcome the disadvantages of the traditional locking mechanism for Distributed Database Systems (DDBS), such as the low transaction concurrency and the high communication costs, this paper studies the traditional mechanism with Two-phase Locking (2PL) protocol, and redefines the lock types and their compatibility matrix in DDBS, designs the structure of the Lock Table, improves the lock policy and the lock algorithm. Those make up of a new locking mechanism for DDBS. The experimental results show that this mechanism can intensively control and flexibly manage the requirements for locks with improved 2PL protocol and multi-granularity locking, and effectively ensure serializing scheduling of transactions and decrease the costs of communications while locking. It obtains the better transaction concurrency than the traditional mechanism. © 2014 ACADEMY PUBLISHER.

Trustworthiness plays an important role in service activities. However, it is not easy to define and compute the service trustworthiness as the evidence involves several information from different service party and maybe conflict at the same time. We discuss the definition and computation method of trustworthiness in this paper. The trustworthiness is acquired from service provider, service user, and service agent and then it is fused based on D-S evident theory. Finally, we testify that the trustworthiness can improve the precision of service discovery via simulation experiments. © 2010 IEEE.

Activity instance oriented handling is a new means for vertical optimization of process cases. Unlike our previous batch processing mechanism in workflows, it focuses on the data characteristics of activity instances and utilizes explicit knowledge for execution optimization. This paper introduces its concept and investigates its modeling and enactment mechanisms. It uses activity instance pattern as a base to model and represent the knowledge for execution optimization. The system design for activity instance oriented handling and related algorithms are also proposed. © 2011 IEEE.

Our previous work has preliminarily investigated the batch processing model and its implementation. To solve the problem of setting batch processing areas for the applications of batch processing in workflow, this paper proposes a method of discovering batch processing area from workflow logs. Its mining process includes phrases of mining initial workflow model, identifying batch processing feature of activity and discovering batch processing area in the initial workflow model. The result of simulation experiments shows that this method can work effectively for several different size of data sets. © 2010 IEEE.

Batch processing process denotes the process used in the workflow management systems (WfMSs) supporting dynamic batch processing. During the run time of their concurrent process instances, multiple activity cases of the same type may be vertically combined together according to some batch logics and submitted for execution as a whole. Therefore, it is necessary to study the actual way process instances are executed. In this paper, we propose an algorithm to mine batch processing process from system logs. A case study is also done to illustrate its effectiveness. © 2010 IEEE.

In this paper we propose a new kind of geometry driven subdivision scheme for curve interpolation. We use cubic Lagrange interpolatory polynomial to construct a new point, selecting parameters by accumulated chord length method. The new scheme is shape preserving. It can overcome the shortcoming of the initial four point subdivision scheme proposed. © (2013) Trans Tech Publications, Switzerland.

In hospitals, there are usually many legacy equipments and software systems, which may not provide standard interface for integration or even do not have its own API for outside accessing. This makes it very hard to integrate those legacy systems with health information system. It becomes a big challenge for health information integration if you want to provide a total Health Information System for hospitals. To solve this problem, this paper designs an effect and flexible health images data capture methods and apply it in certain hospitals. It uses windows Hook API to capture the output data or system operation behavior and submit to health information system. Finally, they can be renewed by a special algorithm developed by us. ©2011 IEEE.
