Abstract: The aim of project has been to design and develop the invoice component for an electronic procurement system that is capable of eliminating manual steps in the process with the objective of reducing the cost. The requirement initiated from Sweden for a direct client of Marakanda AB. The solution provided is suitable for this client as well as being generic for any client for whom the procurement is an integral part of their business process. The system developed is capable of extracting information from invoices which reach the system in XML format. The retrieved information is then processed automatically whilst still giving the user the option for manual interventions. During the process affected parties are notified automatically via email. To achieve this, message driven beans have been used. Overall the system used component based architecture which is inherently suitable for large business applications that are building gradually. The component developed during this project is support by few other existing modules of the company and those components were considered out of the scope of this project. The project managed to meet its objectives and the system developed was considered as acceptable from the client in question. At Marakanda AB this system is now in the process of being implemented at the customer’s site and so far has been quite successful in attracting few more customers. 2013-11-11T00:00:00Z https://dl.ucsc.cmb.ac.lk/jspui/handle/123456789/820 Title: Web Based Call Traffic Optimization and Base Station Management System Authors: Gunarathna, D.A.R.P. Abstract: The proposed Call Traffic Optimization system is a well functioning and fully automated system which will identify and indicate the congested base stations to take the necessary action. This Artificial Intelligence decision support system will help to do the research and development in CDMA base station congestion because of its ability to define and redefine the rules to identify base station congestion by the user. At the same time when a new base station is proposed to be constructed, the Base Station Management System will coordinate and involve all the departments for its work flow and improve the efficiency effectiveness by giving transparency between departments. The proposed application menu should cater for wide expansion of the application. The menu should be a explore view and the Hierarchy of the modules should be able to define or redefine in the system by the system administrator according to the user requirement. 2013-11-08T00:00:00Z https://dl.ucsc.cmb.ac.lk/jspui/handle/123456789/818 Title: WEB BASED EXPORT TREND ANALYZER AND DECISION SUPPORT SYSTEM Authors: Waidyaratna, M. Abstract: EXPORT TREND ANALYZER (ETA) is a database driven decision support system which is delivered on World Wide Web. The system primarily seeks to assist policy makers, international trade promoters, market and product development officials of business support organizations (BSOs) or researchers for online retrieval and analysis of statistical data pertaining to international trade transactions originated from Sri Lanka (exports). Customized and dynamically created reports are enhanced with regression analysis and graphical depiction. This would facilitate sensible and rational decision making and recommendations in formulating export promotion strategies, setting targets and planning activities. Exports sector in any economy, takes leading role in achieving a realistic growth in the Gross Domestic Production (GDP), thereby enhancing the quality of life of it’s inhabitants. It is critical for an economy of a country like Sri Lanka which is constrained by relatively small size of the domestic market. The contemporary international market is governed by vigorous and dynamic competitive forces which result in continuous changes in market requirements/trends and quick switching of “windows of opportunities”. Hence it is of paramount importance that we continuously monitor and analyze the twists and turns of the international market place, facilitating our policy makers to be sensitive and reactive to the changing environment. In this regard researchers or officials of export related business support organizations and even exporters themselves need extensive analyzes of the trends and patterns of products exported from Sri Lanka, suppliers of theses products and the export destinations. The ETA system seeks to provide a reliable, dependable and flexible IT solution to facilitate such efforts with wider geographical reach. Implementation of Export Trend Analyzer (ETA) is backed by fully open source bundle of LAMP (Linux, Apache, MySQL, PHP) although the WAMP (Windows, Apache, MySQL, PHP) which is a derivative of LAMP architecture is used in the development process together with iterative prototyping approach. 2013-11-08T00:00:00Z https://dl.ucsc.cmb.ac.lk/jspui/handle/123456789/816 Title: Design, Modeling and simulating an IP based Public Voice Network Topology Authors: Jayatilleke, M.S.E. Abstract: Voice over the TDM based PSTN has been the main source of communication for the public over decades. With the rapid development of the Internet Protocol and its applications, voice transmission over IP networks has become popular. A technology so called Voice over IP (VoIP) has been evolved to facilitate such services. It is predicted that, in the future the conventional PSTN system will gradually be replaced with an IP based converged network which will carry both data and the voice. Users will have a single access line to the network for accessing the data and voice. Developed countries have taken steps in advance in terms of technology, standards and policy to take the full benefits of the IP convergence in public networks. This project has identified the need of such an IP based public converged network for Sri Lanka to cater her burning need of communication infrastructure development. This report is a part of the individual project based on the design and modeling of a public IP based voice network topology for Sri Lanka. The aim of this report is mainly to discuss the project background, requirement analysis and to propose a design for the VoIP infrastructure in Sri Lanka. Efforts were focused in identifying the weaknesses in current telecommunication infrastructure in Sri Lanka and the reasons as to why we are migrating to an IP network. Primary issues that are associated with and must be addressed in designing a large scale VoIP network that is capable of supporting full PSTN equivalence also were taken into consideration. Theories behind the IP Convergence and the technologies that are used to implement a public IP network are also be discussed in brief. Proposed infrastructure section will discuss the possible challenges that has to be over come in proposing a converged solution. The proposed solution and the implementation of the test setup to model the proposed solution has been described in detail. Measurements and evaluations that have to be done on the test setup, based on which estimations in terms of device capacity and scalability are also discussed. Efforts are focused in designing a topology which is technically feasible and scalable. Quality of Service in VoIP was focused in a similar project carried out by Mr. Nadesu Yogeswaran under the supervision of Dr. Nalin Ranasinghe of UCSC. The objective of the project is to propose a design and a model for an IP network which will gradually replace the existing PSTN network and deliver the services equivalent to PSTN in terms of quality and reliability. This dissertation report is an attempt to demonstrate the efforts made to achieve the above objectives. 2013-11-08T00:00:00Z
