    Real time personalized aggregated activity stream for an organization
    (2013) Kajaruban, S; Madarasinghe, BR; Withanage, SP
    In a large organization there is a bulk information pool which is aggregated from internal and external sources of the organization. It is often very hard to keep track of every part of information that is published in different systems. This paper introduces a novel system which is able to automatically personalize the Activity Streams after aggregating and consolidating from different independent systems (e.g. in a software company context: version management system, wikis, bug trackers etc.).It retrieves the information by sensing the activities from these independent systems and then it is processed and transformed into news feed along with its specific standardized format. After generating the news feed, the system personalizes the feed using employee information. Finally, it shows these personalized Activity Streams to the user interface which is able to automatically motivate users to find relevant information easily without either missing any data or losing valuable time. It also suggests more information based on the employee past history. This system solves the problem of 'irformation silos' by reducing and managing information in a structured way.

    Wi-Fi based Positioning system
    (2011) Liyanagedara, LGAI; Madarasinghe, BR; Tillekeratne, MAT; Ubhayaratne, KNI; Dias, D
    Real Time Location-estimation systems (RTLS) developed for outdoor environments have shown significant errors due to changes in atmospheric conditions, multipath propagation and inherent signal strength variations. In this paper, we present an improved Wi-Fi based RTLS solution for the outdoors that reduces the above impacts. In addition this paper presents the development of a portable device for implementing the above RTLS solution. The research makes use of Euclidean, standard deviation based and triartgulation algorithms. Data smoothening is done to reduce the multipath propagation issues. The different algorithm combinations are compared via their error cumulative distribution functions.
