    Development of an automated microscopic imaging system for TB screening
    (Institute of Electrical and Electronics Engineers, Inc., 2016-12) Samarasinghe, HDTG; Sampath, LLR; Thilakarathna, HRMMVB; Gopura, RARC; Lalitharatne, TD; Amarasinghe, YWR; Rajapakse, A; Prasad, WD
    This paper proposes an automated microscopic imaging system (MIS) for TB screening. Mainly, the system consists of integrated hardware and software components for sputum smear slides feeding, controlling and carrying out microscopic and image processing functions of the system. The MIS is used to distinguish TB positive and negative cases. The hardware system and controlling mechanism of MIS are discussed. Algorithms for focusing of the microscope and image processing are presented. Experiments are carried out to evaluate the proposed automated microscopic imaging system

    A novel mems motor based on thermal actuation
    (IEEE, 2016-04) De Silva, AHTE; De Silva, DDN; Perera, KDCJ; Priyashantha, AMB; Sampath, LLR; Darshan, P; Jayathilaka, WADM; Amarasinghe, YWR; Jayasekara, AGBP; Bandara, HMND; Amarasinghe, YWR
    It is essential for the Micro Electro Mechanical Systems (MEMS) research industry to introduce novel concepts of micro motors to overcome problems in existing micro motors. This paper propose a novel concept of a micro motor using kink actuators and reciprocating rack and pinion assembly. Design details of the reciprocating rack and pinion is discussed in the paper. A detailed analysis of structural, transient, thermal, electrical properties was performed using the COMSOL software is also discussed. Finally a fabrication method is purposed using electron beam lithography and ultraviolet lithography.
