    Pros and cons of using structurally insulated panels in Sri Lanka
    (Department of Civil Engineering, University of Moratuwa, 2014) Jayathilake, L; Baskaran, K; Hettiarachchi, MTP
    Structurally Insulated Panels (SIPs) are extensively used in energy efficient buildings all over the world. SIPs can be simply introduced as a building material consisting of an insulating layer in between two structural wythes. Since SIP technology is fairly new to Sri Lanka, only few studies have been carried out to check thesuitability of SIP technology in Sri Lanka. SIPs can be used as walling materials, roofing materials and for slab construction instead of conventional building materials such as burnt clay bricks, cement sand blocks or conventional reinforced concrete slabs. This paper describes an experiment carried out to determine the thermal performance of SIP wall, Cement block wall and Burnt clay brick wall model houses. Further,this presents the results obtained from a computer simulation regarding the cooling loads required for above mentioned models. A cost comparison has been done to evaluate the costs of various wall construction techniques used in Sri Lanka. As a whole, this paper describes pros and cons of using SIPs in Sri Lanka.

    Video colorization dataset and benchmark
    Abeysinghe, C; Wijesinghe, T; Wijesinghe, C; Jayathilake, L; Thayasivam, U
    Video colorization is the process of assigning realistic, plausible colors to a grayscale video. Compared to its peer, image colorization, video colorization is a relatively unexplored area in computer vision. Most of the models available for video colorization are extensions of image colorization, and hence are unable to address some unique issues in video domain. In this paper, we evaluate the applicability of image colorization techniques for video colorization, identifying problems inherent to videos and attributes affecting them. We develop a dataset and benchmark to measure the effect of such attributes to video colorization quality and demonstrate how our benchmark aligns with human evaluations.
