  • Prasanga, DK; Abeykoon, AMHS; Prasad, SKLB; Udawatta, L [Conference-Abstract]
    In a healthy heart, there is no any abnormal blood flow takes place inside, in addition to the usual blood circulating pattern. However when the valves or tissues inside the heart are in diseased conditions, this usual ...
  • Prasanga, K; Prasad, LB; Perera, WARP; Noshan PKL; Abeykoon, AMHS; Udawatta, L [Conference-Abstract]
    Cardiac murmurs are the sounds produced by the abnormal passage of the blood flow inside the heart due to the diseased value of tissues. Identifying the type of the murmur can diagnose the cardiac pathology related to that ...
  • Fernando, S; Udawatta, L [Conference-Abstract]
    This paper describes the comparison of accuracy and performance of two machine learning approaches for visual object detection and tracking vehicles. The first is a neural network based approach. The classification was ...
  • Dharmadasa, IT; Lucas, JR; Udawatta, L; Wijayapala, WDAS [Conference-Extended-Abstract]
    Main intention of Geophysical resistrvity surveying is to interpret the subsurface conditions for engineering applications. The earth exhibits a far from uniform structure and therefore the surface resistivity varies from ...
  • Abeykoon, AMHS; Udawatta, L; Dunuweera, MS; Gunasekara, RT; Fonseka, M; Gunasekara, SP [Conference-Abstract]
    This paper introduces a low cost method of sensing position using a optical sensor. Main objective of this study was to overcome the shortcomings associated with the conventional contact type of position sensors using ...
  • Wijesooriya, PN; Abeykoon, AMHS; Udawatta, L; Punchihewa, A; Nanayakkara, T [Conference-Abstract]
    Elephants have to maintain stability of a body weighing 2700 kg - 4500 kg in a wide range of unstructured terrain conditions. To achieve this, the dynamic walking control strategies of an elephant should be able to ...
  • Jayasekara, AGBP; Udawatta, L [Conference-Extended-Abstract]
    Signature recognition has many practical applications in criminology, document authenticity, banking sector and organizational level record keeping. A trained template of sample input signatures can be used to recognize ...
  • Fernando, PBC; Gunasekera, GSM; Gunasinghe, SR; Udawatta, L; De Silva, CR [Conference-Extended-Abstract]
    Given the limitations of human perceptions it would be impossible to classify the images manually. The IRIS (Image Retrieval and Indexing System for Data Mining) system that we have developed is a solution! to this problem. ...
  • Udawatta, L; Jayasiri, DDAS; Pallegedara, A; Dassanayaka, P
    This paper describes how fuzzy control can be applied to a sonar-based mobile robot. Behavior-based fuzzy control for robot behaviors was designed using sonar sensors. (10) Throughout this research work experimental ...

  • Fernando, WSP; Udawatta, L [Conference-Abstract]
    This paper describes the methodology for identifying a moving object by a fast dyadic image downscaling combined with a neural network (a multi layer perceptron). Given a sequence of images here we basically try to detect ...

  • Dunuweera, MS; Fonseka, M; Gunasekara, RT; Gunasekara, SP; Harsha, AM; Abeykoon, S; Udawatta, L [SRC-Report]
  • Dunuweera, MS; Fonseka, M; Gunasekara, RT; Gunasekara, SP; Harsha, AM; Abeykoon, S; Udawatta, L [Conference-Abstract]
    This invention relates to a method of sensing positions in application such as mobile robotic applications. The main objective of this invention is to overcome certain issues related to position detection mechanisms available ...
  • Udawatta, L; Harishan, K; Heendeniya, HKCB; Jayaweera, JAGK; Sivakaran, N [Conference-Abstract]
    The paper presents about studying and experimenting on optimal configuration of standalone solar panels, and the implementation of a control module named 'SOLAR OPTIMIZER' Optimal configuration of a ...
  • Jayasekara, B; Lucas, R; Namasivayam, S; Udawatta, L [Article-Abstract]
    The electrical and electronic industry in Sri Lanka, although relatively small in itself, is a key service industry to other industrial sectors as well. In the study presented, a sample of around 300 companies/industries ...

  • Abeyratne, MGAP; Welihinda, SM; Udawatta, L; Karunadasa, JP [Conference-Abstract]
    In this paper we demonstrate how the Robotic Technology theories are applied to solve the real world problem in bipedal walking of robots. Since there has been an increasing interest in bipedal locomotion, the modeling of ...
