A Comparison of Delta-Communication Technologies and Techniques Dissanayake, NR; Dias, GKA Delta-Communication can be seen as the power of Rich Internet Applications, and there are different Techniques and Technologies available for the development of Delta-Communication, which should be selected carefully into the Rich Internet Application development. Enough discussions are not available, which compare and contrast these Delta-Communication development Techniques and Technologies towards supporting decision making of selecting them. This paper provides an overview of the contemporary Techniques and Technologies available for the Delta-Communication development, contextually compares them aligning to some selected criteria, and finally discusses some facts to be considered when selecting them for the Rich Internet Application development. A literature survey on the Delta-Communication development Technologies and Techniques was conducted, which was followed by a series of experiments towards getting the empirical evidence for the comparison. During the contextual comparison, the Simple Pull Delta-Communication was identified as the least complex technique and the Websocket was noted as the highest complex technology. Article Full Text

An infrastructure service suggestion system for data communication network : Local area network Halwatura, HAHV; Kathriarachchi, RPS Network Infrastructure development includes building of networks such as LANs, WANs, Intranets and Extranets. This is a responsibility of the Network Engineers or the network architects. They should have the knowledge as well as the skills to plan and design a data communication network, be conscious about the best place to have communication lines, be updated with the latest network equipment and be aware about the hardware and wiring needed for the buildings. These tasks are more complex for larger organizations which needs more accuracy, dedication and flexibility in their networks. Therefore the solution proposed in this paper to reduce these challenges of a network engineer is a Data Communication Network Infrastructure Recommendation System. This system will be able to get any floor plan and analyse it in order to provide recommendations on the installation of the main networking components such as selecting the server room and deployment of the backbone cable. It also allows the user to draft the plan with endpoints by the drag and drop function, keep a log fie of the saved data and also to send a System generated network layout of the plan to the customer. The software is being developed by making use of the Image processing technology with the help of the MATlab Software and C#. A series of algorithms will be used of achieve the objectives of the software. This software is non-identical to current software in the market. Article Full Text

An Online Help Desk System to Help Students in Learning Salgado, MND; Charuka, PU; Bashitha, KP; Eshwarage, SC; Ariyaratne, MKA This paper reports about a field study done on online helpdesk system for General Sir John Kotelawala Defence University (KDU) and about the system prototype which was built according to the analysis of gathered data. When considering the current learning process prevailing at KDU, when participating in lectures, students do not get a chance to present their problems to the lecturers very often. Therefore, we address the problem of not having an opportunity for the students, to solve their problems that arise during the lectures. To overcome this problem, a Web Based Help Desk System was introduced for KDU. Through this Online Help Desk System, students will get the opportunity to present their problems to the relevant lecturers, whenever they need a further clarification on any subject material. Students are facilitated by the option to choose the priority level of a question. So, unlike other help desk systems, this system will ensure that each question posted on the system will be answered as soon as possible according to the priority level preferred by the student, by notifying the lecturers by an email. The accuracy of the provided answers will be assured since, only the authorized lecturers of KDU have the eligibility to get registered to the system as an answer provider. When developing this Online Help Desk System, the focus was given to build a system, which will give more time critical and task sensitive online help. Article Full Text

Domestic Services Management System: A Sri Lankan Perspective Wickramaratne, SHYS; Wedasinghe, N Technology has granted many opportunities for the people in need of employment around the world. It has created marketplaces as well as marketspaces providing a stable economic benefit. However, in this modern society which have plethora types of media & mass communication approaches, so far it still failed to deliver swift and convenient methods to request domestic services. Home repairing services, beauty, and healthrelated services, events organizing related services and business services are few services still discoverable through newspapers and yellow pages in Sri Lanka. This leaves a necessity to create a solid platform for the skilled micro employees to provide their services continually as per the customers’ services requests. A mobile App-based service marketplace will be a good enhancement for the current context to locate, categorize, and provide rates and feedback about nearby micro employees who are willing to provide their services for the domestic customer’s request. This system will categorize their jobs and its work providing more niches to the customer’s request. The main objective of this paper is to emphasize that mobile technologies can be used to enhance the human life by helping them to hire services using a convenient platform. As for the results, this system can influence the 4.7 of an unemployment rate of Sri Lanka (Labour Force Survey, 2015) by creating a separate easily accessible marketplace without any entry barriers for the micro employees who are willing to start their own businesses.
