    Thermal comfort performance monitoring for stationary vehicles under tropical climate
    (2006) Wickramasooriya, IPTS; Witharana, S; Wickramaratne, C; Perera, ULIU
    The thermal comfort in an automobile is provided by the air conditioning system. Generally, in city running, an automobile air conditioner consumes nearly 10% of the fuel burnt by the engine. With the use of shading devices and by parking the vehicle under shades, the heat gain into the vehicle can be minimised. Especially in warm tropical climates, the minimisation of heat gain is of paramount importance as excessive heat gain will result in high interior temperatures, which in turn will demand higher load on the air conditioner while the life of the vehicle interior gets shorter.

    Work design concept as a productivity improvement tool : a csae study of soft drink manufacturing company
    (2008) Vilasini,PPGN; Kahangamage, UP; Samarakoon, P; Perera, ULIU
    The purpose of this paper is to elaborate on how work design concept influenced to the overall productivity of a manufacturing organisation. In order to apply the Work Design concept, a generic model of Work Design is defined. This generic model was then applied to selected work centers of a soft drink manufacturing plant. The results show that when Work Design Concept is applied according to the generic model defined has improved the productivity of the work centers.
