This paper is a parking management system which uses mobile terminal equipment by the client. From the Web server, the client will be served about the information concerned with the location o( parking lot, parking time, and payment after accessing the parking management web site. After the sensor which is set in the parking lot perceives the information about the client's car, it will inform the client of the parking place. This system is designed to control the large and complex parking lot and serves a very convenient interface to the user.

This paper deals with self-tuning of fuzzy control systems. The fuzzy logic controller(FLC) has parameters that an: input and output scaling factors to effect control output. Tuning method is proposed for the scaling factor. In this paper. it is studied to control and to monitor the remote system statues using SOAP for communicate between the server part and the client part. The remote control system is controlled by using a web browser or a application program. The server part is waiting for the request of client part that uses internet network for communication each other and then the request is reached. the server part saves client data to the database and send a command set to the client part and then the client part sends command to controller in a cool chamber. The administrator can control and monitor the remote system just using a web browser. The effects of membership functions, defuzzification methods and scaling factors are investigated in the FLC system.

A general web-based remote lecture system uses video data and audio data to provide synchronize between teacher and students. This system requires high bandwidth, high speed networking, television, compression and computing technologies between server and client for remote lecture over Internet. As a result, this system can decrease an efficiency for lecturing over current Internet. So, this paper proposes a new mechanism calling as ‘Synchronization of WWW browsers between server and client’to cope with above problems and finally pursues low cost needed for real-time remote lecture over Internet. The mechanism means that every browser of teacher and students displays the same page and the action of teacher is transferred to the browser of student. And, this can be implemented by Windows hooking APIs, Memory Mapping, and DLL (Dynamic Link Library) programming technology. This paper points to the design and implementation of LAS (Lecture Assistant Server) and LAC (Lecture Assistant Client) to perform the synchronization between server and client.

In this paper implemented that PDA sends finger images and can finger recognition web service system in realtime. Finger recognition web service system received the finger images and return the recognition result as XML style. because of this it can offer the same service to using wireless PDA as well as using wire internet client. This system consist of mobile client and finger recognition web service provider. Mobile client request finger recognition web service provider using DIME with taken finger image. We can easily receive and see the result of finger recognition without mass finger database in limited storage space of PDA. Finger recognition web service provider offers that receiving finger images and calling finger recognition system after the recognition return the result.

According to increasing of accessing multimedia stream contents, Web services have become popular. However, these Web services are not supported with the same quality to Web clients who frequently access multimedia services. This paper proposes ontological technique to apply client level Quality of Service(QoS) that provides two different levels to serve Web service with proper quality by contribution value. And, it describes with UML(Unified Modeling Language) how to relate QoS and SLA(Service Level Agreement). Main contribution of this paper is to support client level QoS and SLA and to use Ontology for it. Therefore, this work uses an ontology-based approach to organize QoS and SLA, enabling semantic classification of all Web services based on domains and QoS and SLA attributes.

CoSlide is a collaborative system, extending the Jakarta Slide WebDAV server. The CoSlide server provides group workspaces for collaborators. CoSpace is a client which supports various collaborative authoring activities on the CoSlide server through the WebDAV protocol. CoSpace provides graphic user interfaces to support effective interaction among the collaborators, managing the shared resources for them. However, during collaboration, simultaneous modifications on the content of shared resources might cause conflicts among the content of the revisions made by the collaborators, leading to serious problems on project progress. In this paper, we describe an extension of the CoSpace client to solve the problem. The extended CoSpace client supports the remote version management facility through which the collaborators can manage the versions of the associated server resources in the distance. Also, to identify the changes of the text files such as program source codes, the extended client provides the facility for comparing two versions and displaying the differences in a visual manner. In addition, it provides the version management of a whole workspace and the removal of all the unnecessary versions of the designated resources.

The search method that web services offers has its limitations. The search service considers only functional factors based on the client's preferences. In order to improve the web service search - which alone only considers functional factors - our research introduces an execution phase which performs both functional and non-functional factors by utilizing WSDL and matching information. Our research studies the architecture of both the service selecting method and the selecting process to help determine the best service solution for the client. We do so, taking into consideration the client's preferences. Our research also studies selecting methods for the best overall service. This service not only considers the matching of functional factors provided by the web service's selecting process, but it is also accommodating by matching the information as defined by the client. This paper research can offer the best quality service preferred by any end-user. Again, this is done by utilizing web services that considers the user's non-functional factors identified by the web service's selecting process and also by extracting matching information.

The paper is design and implementation of the system to support security communication between a Web Browser and a CGI program by a Web Server using PKI(Public Key Infrastructure. This system uses GSS(Generic Security Service)-API to communicate with PKI, offers a Web user a Client Proxy, and offers a CGI developer there library functions related with security. TLS(Transport Layer Security) supports security communication between a Web Browser and a Web Server, but the system supports security communication between a Web Browser and a CGI program as the protected data received from a Client Proxy are sent to a CGI program, and the CGI program decrypts the data using the library functions supported by this system.

Over the past few years, a number of studies have been made on web map services, which enable the GIS user to access spatial data through the web. They, however, have focused on only implementation techniques separately, such as map client implementation, map server implementation, communication between client and server, and the map data representation. Therefore, it is hard to share and practical use the spatial data, because they does not ensure interoperability in heterogeneous map servers. In this paper, we have designed and implemented the web map server with open architecture, which complies with the standard interfaces proposed by OpenGIS Consortium (OGC). In particular, we have extended the OGC’s interfaces for a map server to support one or more data sources. This paper has contributed to construction and practical use of web map services by newly proposing the method of implementation of a map server, which could be reused regardless of the types of data sources.

According to the rapid evolution of internet, the number of internet users has greatly increased, so that the web servers are getting more important. If there are a great number of users trying to connect to a popular web server, the load of the web server will increase rapidly, so that failures may occur or web services may stop. An efficient load monitoring technique is required for the available web services and the performance management. The traditional techniques for load monitoring of web server using the client-server method have the problem that the server programs in client-server method must be pre-installed to all web servers. This paper implements web server load monitoring system using the mobile agent in order to overcome the problem of client-server computing. The system based on the mobile agent has no need to install the program in advance and it reduces the network traffic and the additional overheads in web servers.
