Replicating human-like proxemics behavior in approaching mechanisms of a domestic service robot

Samarakoon SMBP [Thesis-Full-text]

Development of intelligent service robots is a growing research area within the eld of robotics. Service robots have been developed to enhance the living standard of people. Users of these service robots are not experts ...
Fractal analysis of creeping discharges propagating over solid insulators immersed in insulating oil

Ediriweera, WEPS [Thesis-Full-text]

A solid/liquid insulation interface is considered to be one of the weakest points in a composite insulation system as it facilitates creeping discharges on the interface when the electric field strength exceeds a threshold ...
Modelling sweep frequency response of power transformers

Jayarathna KLIMPB [Thesis-Full-text]

Condition monitoring of power system components is crucial in order to supply quality and uninterrupted power supply to its consumers. Among other components, the power transformer is considered to be one of the most ...
Impact of high penetration of solar PVS on harmonics in LV distribution networks

Anurangi, RO [Thesis-Full-text]

Present trend of using solar photovoltaic (PV) technology for generating electricity has marked a rapid growth in the number of grid connected solar PV systems which has been reported to make a considerable impact on the ...
Reactive Power Dispatch By Distributed Generators Through Step Load Flow Simulation And Genetic Algorithm

Abeysinghe, AMGGSHB [Thesis-Full-text]

Demand for reactive power in a transmission and distribution network is met by various ways such as through power generating plants, compensation by means of capacitors at the utility grid and compensation at the load point ...
Optimizing Of The Usage Of Samanalawewa Water Resources For Power Generation

Pathiraja, MPW [Thesis-Full-text]

Samanalawewa hydroelectricproject is based on Walawe basin in southern region of Sri Lanka. It includes Samanalawewa reservoir, a water way system and a 120MW power plant as stage (I).Some provisions have been kept for ...
Active vibration suppression with disturbance force estimation

Abeysiriwardhana, WASP [Thesis-Full-text]

Vibration is a basic phenomenon that has attached control engineering’s attention for many decades. Vibration rejection in control systems is implemented with passive, semi active and active vibration suppression systems. ...
Reaction torque observer based force feedback gripper with force lock

Ruwanthika, RMM [Thesis-Full-text]

Haptic information is a bilateral information of the law of action and reaction. Most of the researchers have done experiments on bilateral teleoperation but still they haven’t given much attention on force lock during ...
Leakage inductance calculation of toroidal transformer using finite element analysis

Dodampegamage, NS [Thesis-Abstract]

The researches done on calculating leakage inductance of a toroidal transformer were rare. In this research it is attempted to fill this gap by formulating a method to calculate leakage inductance of a toroidal transformer. ...
Vibration suppression of bilateral tele-operation with virtual impedance controller

Menikdiwela, MP [Thesis-Abstract]

Bilateral tele- operation is one of a major part in robotics as well as in motion control. Most of the researchers have done experiments on bilateral tele-operation but still they haven’t given much attention on vibration ...
Position based friction estimation for precise motion control

Chinthaka, MKCD [Thesis-Abstract]

Friction is often neglected in DC servomotor applications. It valid if the servo motor is small and the frictional torque elements are small when compared to the motor torque. Fixed friction and viscous friction are the ...
Intelligent sensor system for humanitarian demining

Aravinthan, V [Thesis-Abstract]

In any post conflict country, landmines have become a major concern to civilians especially during the resettlement period. Biological Sensors and Metal Detectors are the most common detection technologies used commercially. ...
Voltage control in a Transmission system area with high renewable energy penetration case study : Chunnakam Grid Substation

Wijepala MHP [Thesis-Abstract]

The northern part of Sri Lanka has higher wind and solar penetration. Chunnakam and Kilinochchi grid substations are operating in that area, and they are connected to the national grid via a 132 kV double-circuit transmission ...
