(Department of Computer Science and Engineering, University of Moratuwa., 2017-12) Subashith, SKTD; Perera, I; Meedeniya, D
Today there are many e-learning systems that fulfill the thirst for education. Those e-learning systems have many courses in different fields. There are so many e-classes that teach how to program in many different programming languages. But in most of those e-classes instructors have to spend a lot of time to evaluate assignments submitted by students. If the grading process can be done automatically, it will save lots of time of instructors. There are many systems that use the functionality of evaluating programs automatically. They provide support for hosting online programming competitions, but most of them do not provide platforms for e-classes. Therefore Automated Programming Assignment Grading System (APAGS) is the solution which supports both e-class environment and programming competition environment. The APAGS is a web system which has developed using Symfony framework according to the model, control and view architecture to provide both e-class environment and competition hosting environment. Its main goal is to evaluate the programs and analyse results for both assignments and competitions.

“BLOOD” is one of the most essential necessities of our lives. Mostly during accidents or most of the hospitals issues the need for blood is the common problem. In addition to emergency requirements, advances in medicine have increased the need for blood in many ongoing treatments and elective surgeries. This paper presents an android application blood bank management system that enables individuals who want to donate blood to help the needy. It also enables hospitals to send blood request to the donors who were already registered to the system. The system has developed by using java, PHP, and MySQL as a database system to manage and store the data. The Waterfall Methodology, which is the traditional version and the classic approach of a system development life cycle, is used to develop and build the android based blood bank system. The system targets three types of user: the public who wants to donate blood, the hospitals who need blood, and the admin who manage the system. In this application the system has utilized the Google distance API to find the distance between donors that are in favor of donating blood and hospitals. The android application is readily scalable, efficient and adaptable to meet the complex need of blood for the hospitals.

Ceylon bus routes: a bus route guide
(Department of Computer Science and Engineering, University of Moratuwa., 2016-12) Nimalsiri, NI; Perera, I; Meedeniya, D
Mobility is a basic human requirement for traversing between different locations. Public transport bus service fulfills this requirement by operating according to a published timetable along a route calling at agreed bus stops. Despite its progress at a rapid pace, moving commuters are riddled with problems of finding the correct bus route to reach their desired destinations. The use of mobile phone applications is an attractive alternative to guide passengers through correct bus routes. This paper discusses the project, “Ceylon Bus Routes” which is a Microsoft Windows universal application built as a solution for finding bus routes in Sri Lanka. This application is significant because it works offline and it can be run on any Windows based device. The goal of the application is to display the best routes as well as all the routes between two locations requested by the user. The application also uses GPS technology to track user location in case if the user does not know his or her actual location.
