Kanchana, WAD; Madushanka, GDL; Maduranga, HP; Udayanga, MDM; Meedeniya, DA; Perera, I [Conference-Abstract]

Information visualization is the final process of any data analytics project, which gives an overall insight about the identified trends, patterns and anomalies. Efforts in data analysis become useless when we fail to ...
Optimal terminal configuration for minimizing passengers’ waiting time

Saparamadu, S; Bandara, S [Conference-Abstract]

Irrespective of the friction arrangement for a given terminal size, there will be a geometry that will be optimum with respect to passenger waiting. Quantitative methodology is used to select a suitable terminal configuration ...
Open conductor fault detection

Jayamaha, DKJS; Madhushani, IHN; Gamage, RSSJ; Tennakoon, PPB; Lucas, JR; ayatunga, U [Conference-Abstract]

Detection of open live conductors is a challenging task in the power system operation since it acts as a high impedance fault. High impendence faults (HIF) characteristically has a very low current value which is often not ...
Microstrip patch antenna for partial discharge detection as a condition monitoring tool of power system assets

Ediriweera, weps; Priyanayana, KS; Rajakaruna, RMAP; Ranasinghe, Rakg; Lucas, JR; Samarasinghe, R [Conference-Abstract]

An electric power system consists of a number of critical and expensive equipment that operate under high electric stresses. Failure of such an asset can lead to unscheduled interruptions and incur huge economic losses. ...
Indoor thermal comfort and Carbon Dioxide concentration : a comparative study of air conditioned and naturally ventilated houses in Sri Lanka

Pathirana, SM; Sheranie, MDM; Halwatura, RU [Conference-Abstract]

Carbon Dioxide (CO2) is considered as a useful and easily measurable indicator for the ventilation and air quality of the indoor environment. Although this pollutant itself is not causing serious health issues with lower ...
Extended kalman filter based fusion of reliable sensors using Fuzzy Logic

Das, TK; Harischandra, PAD; Abeykoon, AMHS [Conference-Abstract]

Precise localization for autonomous robots is necessary for advancement in the world of unmanned robotics. Probabilistic algorithms are used to fuse multiple position sensors in order to locate a robot. But failure of any ...
