Design and Implementation of Intermediate Code Translator using String Pattern Matching Technique
Journal of Internet Computing and Services, volume 3, issue 3, 2002, Pages 1~9
The various researches are investigated for transforming byte code into objective machine code which can be implemented in the specific processor using classical compiling methods to improve the execution speed of the JAVA language. The code generation techniques using pattern matching can generate more high-quality code than code expansion techniques. We provide, in this research, the standardized pattern describing methods and pattern matching techniques that can be used to generate the register-based inter-language which is for the effective native code generation from byte code. And we designed and realized the inter-code transformer with which we can generate the high-quality register-based inter-code using standardized pattern described formerly.
A Distant Teacher Training Management System for Effective
Journal of Internet Computing and Services, volume 3, issue 3, 2002, Pages 11~17
The web-based distance education has some problems in managing students despite the merit of getting over the problem of time and space compared with the classroom education or residential course. These problems make the web-based distance learners difficult in achieving the purpose and the standard of goal. And they drive the manager in charge of the web-based distance education into worries. The manager of the distance education should keep on monitoring students' participation and response, and then give the appropriate feedback to the students. But, the existing distance education system neglects to support efficient management function, for it puts emphasis on the activity of teaching and learning. Therefore, the purposes of this study are to extract the factors that are necessary to manage the distance education for training teachers, to realize the effective management system which can offer a proper feedback in the distance education for training teachers through the application of those factors to the training program, to make it possible to change the management system flexibly according to the curriculum and the computing setting.
A Cyber Evaluation System Using User Profile
Journal of Internet Computing and Services, volume 3, issue 3, 2002, Pages 19~29
Recently, cyber evaluation systems on the Web-based remote education do not consider the personalized characteristic and propensity of individual students. Especially, in setting of the questions far examination, the traditional simple and general methods for all students group have been used for evaluation. This paper proposes on efficient cyber evaluation system using user profile. First, questions are filtered by using user profile for the personalized characteristic and propensity of individual students, This personalized characteristic and propensity have been disregarded in traditional evaluation systems. And then, filtered questions are set for examination, Therefore, efficiency of the evaluation system is enhanced and students make good results from their study. When user profile is adapted, the setting method of question for examination have combined category-based method with keyword-based method. This make students get the interest and pleasure for questions.
IDREF-ID Attribute Reference Modeling of DTD for Legacy Database
Journal of Internet Computing and Services, volume 3, issue 3, 2002, Pages 31~38
A method of DID generating step is suggested for applying the XML technology to the information data extracted from the Legacy databases. The IDREF-ID attribute reference modeling is used for representing the complex relationship between tables and excluding the prearranged step of ID insertion. ID Insertion procedure is performed in parallel with investigating the relationship between the tables and the frequent search direction between the table data. As a result, ID insertion procedure can be performed simultaneously with understanding of the IDREF-ID relationship between tables, and DID are also generated.
Development of Domain Model and Reuse Using Model Template
Journal of Internet Computing and Services, volume 3, issue 3, 2002, Pages 39~53
Since domain model affects largely on the development of object model and design decisions, this model is widely used in the object-oriented and component-based system development. Current
methods and UML notation, however, do not support both engineering with reuse and engineering for reuse, This problem causes delay in project development time and inadequate domain model. The integration of extended UML notation and reuse process method can provide a solution to the reusability problem. In this paper, we designed UML based domain model template for the reuse of domain model and proposed domain model development method for the reuse of analysis information, In addition, it was possible to represent reusable domain model template in UML and to develope domain model in the internet sales domain.
A Study on a Transferring Method of Video Stream to Existing Handphones without Downloading Additional Software
Journal of Internet Computing and Services, volume 3, issue 3, 2002, Pages 55~66
This paper proposes a real-time transferring method of captured video stream to existing handphones without downloading additional software. For real-time transferring of captured vid대 data to handphones, two methods, the WAP based pull-method and the WAP based push-method, are proposed in the paper. Also for transcoding of captured frame into a WBMP image, a threshold setting method which uses the average value of total values of pixels in a scene is proposed. The methods we proposed are implemented in stream engines as video transcoding filter(called WBMPFilter) and video transferring medium(called WirelessMedium). And the experimental system shows 1 frame per 3 seconds transfer of video to existing handphones.
An ABR Service Traffic Control of Using feedback Control Information and Algorithm
Journal of Internet Computing and Services, volume 3, issue 3, 2002, Pages 67~74
Asynchronous transfer mode (ATM) can be efficiently used to transport packet data services. The switching system will support voice and packet data services simultaneously from end to end applications. To guarantee quality of service (QoS) of the offered services, source rate to send packet data is needed to control the network overload condition. Most existing control algorithms are shown to provide the threshold-based feedback control technique. However, real-time voice calls can be dynamically connected and released during data services in the network. If the feedback control information delays, quality of the serviced voice can be degraded due to a time delay between source and destination in the high speed link, An adaptive algorithm based on the optimal least mean square error technique is presented for the predictive feedback control technique. The algorithm attempts to predict a future buffer size from weight (slope) adaptation of unknown functions, which are used for feedback control. Simulation results are presented, which show the effectiveness of the algorithm.
A Design and Implementation of XML Repository System based on EJB Components
Journal of Internet Computing and Services, volume 3, issue 3, 2002, Pages 75~85
Nowadays for reliable software and cost reduction there are many research works on software development based on component, One of the challenge in designing a component-based system is determining which components are required and where they fit in the overall system architecture. In this paper, we developed three EJB components, the first is for transforming XML DTD to relational database schema, the second is for storing XML document in relational database, and the third is for transforming XML document by retrieving relational database, By assembling these three components, we developed XML Repository system finally.
A Study on the Design of Switch for High Speed Internet Communication Network
Journal of Internet Computing and Services, volume 3, issue 3, 2002, Pages 87~93
A complex network and a parallel computer are made up of interconnected switching units. The role of a switching unit is to set up a connection between an input port and an output port, according to the routing information. We proposed our switching network with a remodeled architecture is a newly modified Banyan network with eight input and output ports. We have analysed the maximum throughput of the revised switch. Our analyses have shown that under the uniform random traffic load, the FIFO discipline is limited to 70%, The switching system consists of an input control unit, a switch unit and an output control unit. Therefore the result of the analyses shows that the results of the networking simulation with the new switch are feasible and if we adopt the new architecture of the revised model of the Banyan switch, the hardware complexity can be reduced. The FIFO discipline has increased by about 11% when we compare the switching system with the input buffer system. We have designed and verified the switching system in VHDL using Max＋plusII. We also designed our test environment including micro computers, the base station, and the proposed architecture. We proposed a new architecture of the Banyan switch for BISDN networks and parallel computers.
