Title: Prediction of Unemployment and Solutions from Labour Force Authors: Somaratne, K.C.C. Abstract: The major aim of this research is to forecast the unemployment using the Labor force dataset. At present, unemployment is a critical problem in Sri Lanka .Government is still searching the specific solutions or reasons for the unemployment. According to the Census and Statistics Department unemployed means, Persons available and/or looking for work, and who did not work and taken steps to find a job during last four weeks and ready to accept a job given a work opportunity within next two weeks are said to be unemployed. Since unemployment is a majorfactor in determining how healthy an economy is, predicting the employability is very useful for the economy of the country. It is very useful to predict the employability or unemployability of a person with respect to the valuable crieterias to make solutions for the unemployment. In this research it is going to present a basic approach, taken for predict the unemployment and comparing the statistical approach and Artificial Neural Network to predict the unemployment. The research was performed with the idea of identifying the most efficient and effective method among above two .The prediction power was measured using the ANN and the Logistic regression on training and testing dataset of the Labor force. Three different training algorithms were used to train ANN containing a single hidden layer of ten nodes to compare the performance. The Artificial neural network designed using the Matlab and Logistic regression was performed using the R studio. Artificial neural network created using the Matlab was connected to the Visual studio to show the results.

Title: Using Computer Games to assist Teaching Mathematics in Schools Authors: Pathirane, H. P. B. C. Abstract: Ever since technological advancements started to appear and gain public acceptance educationists wanted to adapt and use it for the betterment of teaching and learning. Moving Pictures, Radio, Television, PCs, Internet and Smart phones are just some examples for this. Each of them was thought to revolutionize the education as we know it. Many of them did, at least to a fair extent if not to the extents initially predicted.One of the technologies praised by the education researchers, video games stood out from the rest for the unique qualities they showed such as ability to intrinsically motivate and emotionally engage the players with the game. It has been shown that video games are capable of making significant impact to the way students learn, and at the same time video games attracted some negative reputation mainly because of the excessive affection shown by the younger generations towards them. Many researches have been done to investigate how educational games could be developed brining out their positive features and merge them with existing educational system. Having realized the importance of Mathematics education, and the fact that many of our students are struggling at it, this research attempts to see how the power of electronic games could be used to help students achieve a better understanding of and practice in solving mathematical problems, particularly in Geometry. Extensive study has been carried out on what motivates young generations to spend so much time playing electronic games, and at the same time it was investigated why the educational games, also known as serious games have failed to achieve the same attraction. Strengths, weaknesses, opportunities and threats presented by electronic games have been discussed so informed decisions can be made in game design process. MathCraft, a prototype game was designed and developed with the intended audience being grade 9 to 1l students of Sri Lankan school. MathCraft has a fantasy storyline and presents its players mathematically inspired tasks to be completed. The game was evaluated with sample set of students, and it was shown MathCraft motivates and engages students with subject matter, than traditional form of exercises. Finally, future extensions and improvements have been presented which would allow real use of electronic games as a teaching aide in schools.

Title: Search mechanism for overcoming the suplicated product searches done in multiple e-commerce systems Authors: Rathnayake, D. M. S. P. Abstract: Along with the fast improvement of computer science, the businesses took different aspects to enhance their customer experience. As a result most of the small to large scale businesses are now using INTERNET to distribute their goods and services among the customers. This mechanism is widely known as e-Commerce or electronic commerce, which is a proven way of increasing the business revenue alongside by providing excellent services to their consumers. With the high demand of e-Commerce mechanisms used, customers are expecting more and more optimized service from their vendors. As the customers are more keen about their purchases, they tend to do the same search in different e-Commerce web portals to get the best out of each. But this may cause unnecessary time,effort and cost consuming for the customer as well as the vendor. Since the same customer do the same search in different web portals to figure out the best fit for his requirement there is a need for an alternative mechanism. This research discuss about this duplicated searches done by customers and suggests a better alternative to avoid it via an API mechanism. Also this problem of duplicated searches has verified by going through the evolution of e-Commerce via past researches and by examining the responses gathered from a sample set of individuals.The survey run among set of individuals highlights that due to reasons such as lack of alternative method, time consumption and filtration issues etc., people are expecting an alternative. The research has mainly focused on how to provide a single search methodology which returns the relevant results from a collection of existing e-Commerce web portals who provide APIs. The prototype proof of concept was built as a web based system by using technologies like PHP, HTML, CSS, jQuery and XML. It avoids the duplicated individual searches done by users in provided sample sites which are “eBay”, “BestBuy” and “FlipCart”. Other than this it allows to filter all three site’s results at once and meanwhile the logged in users gain more advantages such as viewing their past favours and historical information, last viewed products etc. This research is open for further investigation on combining the results from e-Commerce web portals which does not support any API. Through showing that the existing e-Commerce search mechanism consists of many defects, this research highlights the importance of a combined search engine which avoid duplicated searches done by customers in individual websites.

Title: Secured network platform for a peer-to -peer auctioning system Authors: Mendis, Dineth Abstract: Transactions have been taken place all around the world many years back and still it has been a major necessity to the people all over the world. In the past, the traditional economic system has played a major role in both monetary (cash is involved) and non-monetary (cash is not involved) transactions. But with the rapid growth of internet, people have used to fulfil most of their needs through internet. This situation can be seen more when in monetary transactions. With this impact, the traditional economic system no longer exists. It has moved into a new era which people do their regular transactions online in a much efficient and convenient way. This concept is known as E-commerce. E-commerce includes retail shopping, banking, stocks and bonds trading, auctions, airline booking, movie rentals or nearly anything which can imagine in the real world. But the Existing E-commerce model places the content and the transaction logic on a central website or a set of server farms. This has many drawbacks. Centralized indirectly implies that managing system from a single point. This leads to a single point of failure. On the other hand centralized means the local user settings can be overridden by the central governing body rules. That can cause inconvenience. The De-centralized architecture comes into play where it can overcome most of the issues which the centralized systems face. A peer-to-peer application uses a decentralized architecture and minimizes the risk of centralize failures and other drawbacks. A peer-to-peer auctioning system allows companies and buyers to meet directly. They can define their own set of rules to do the transaction. The main concept is distributing the transaction logic and content among the peers. But still there can be frauds and trust issues even if it is a peer-to-peer application. These can be categorized as security issues. If a peer-to-peer auctioning application can be implemented with addressing some common security issues facing in an auctioning system, it would be beneficiary for both buyers and sellers.
