A Molecular dynamics study on viscous and thermal properties of Nanofluids

Somarathna CN [Thesis-Abstract]

The aim of this study is to understand the microscopic behavior of heat and momentum transfer in nanofluids. With nanofluids reporting enhanced thermal conductivities (𝜅) and viscosities (𝜂), a microscopic understanding ...
Optimising the operational parameters and conditions to enhance the environmental sustainability of turning operation

Fernando WLR [Thesis-Abstract]

The manufacturing sector accounts for nearly 40% and 25% of global energy and resources consumption respectively. The die and mould manufacturing (DMM) sector, contributes largely to the energy and resource consumption ...
Development of a real-time grasping pattern classification system by fusing EMG-vision for hand prostheses

Perera GDM [Thesis-Abstract]

The Electromyography (EMG) based trans-radial prostheses have revolutionized the prosthetic industry due to their ability to control the robotic hand using human intention. Although recently developed EMG-based prosthetic ...
Investigation of effect of human robot interaction with lower limb exoskeletons

Chandrasiri MDSD [Thesis-Abstract]

Continuous development of exoskeletons (wearable robots) is essential to enhance the user experiences and performances of the wearable device. Therefore, it is necessary to determine human ergonomics and the comfort ...
Remanufacture for sustainability:

Gunasekara HNW [Thesis-Abstract]

Remanufacturing is the only end-of-life process where used products are brought back to the Original Equipment Manufacturers’ (OEM) performance specification from the customers’ perspective. At the same time, it offers a ...
Development of a multi-rotor aerial vehicle with top mounted counter balanced robotic manipulator

Wijayathunga ND [Thesis-Abstract]

Aerial manipulation has been a growing research area within the past few years. This research area was associated with various application ideas and industries. Researchers implemented different aerial vehicle designs ...
Development and characterization of a tactile array sensor for parallel grippers for use in object manipulation

Weerasinghe DLM [Thesis-Abstract]

Within the era of modern robotics, during research as well as in industry, it is often the case to build robots that can mimic human-object interaction closely. To accom- plish this goal, excellence is required in many ...
Computational tool to model and simulate solar assisted organic rankine cycle with a thermal energy storage

Gamage, SVR [Thesis-Full-text]

The Organic Rankine Cycle (ORC) is considered as one of the most promising methods to convert low grade heat into the power. The ORC energy conversion process is much similar to the typical Rankine cycle except for the ...
An Inviscid model for predicting unsteady forces in doubly connected domains

Gunarathna, MACK [Thesis-Full-text]

Inviscid analytical-numerical model for predicting unsteady forces on two aerofoil configurations is developed and validated with the past literature. First the unsteady inviscid, incompressible and irrotational, except ...
Numerical evaluation of energy labeling test setups of ceiling fans

Casseer DR [Thesis-Full-text]

Ceiling fans are widely used as a means of providing thermal comfort to occupants in an indoor environment all around the world and it contributes to a significant portion of annual energy consumption throughout the world. ...
Design and development of intelligent home automation system (IHAS) for enhanced energy performance

Basnayake BADJCK [Thesis-Full-text]

With the growing distresses on carbon emission and sustainable energy concepts, the whole world appreciates the movements towards sustainable energy consumption. Statistics point out that over 50% of total electricity ...
Development of a robotic ortho-prosthesis for trans-humeral amputees

Abayasiri RAM [Thesis-Full-text]

Over the years trans-humeral prostheses have been developed as a remedy for trans-humeral amputation: the amputation occurs between shoulder and elbow. For thebest usage of the trans-humeral prostheses, amputee ...
Development of an EEG signal based brain machine interface for a meal assistance robot

Perera, KDCJ [Thesis-Full-text]

Most of the countries in the world are facing the problems of aging population and disabilities among the population. Among di erent problems faced by these individuals, self feeding can be identi ed as an important aspect ...
Application of Zimont's turbulent flame speed closure for combustion modeling of a single cylinder spark ignition engine

Eranga, JKL [Thesis-Full-text]

Increasing need to get the maximum power out from fuels while maintaining less amount of toxic emissions has created the requirement of making an optimum IC engine. Numerical simulations play a vital part in determining ...
Design and development of miniaturizes tactile sensors for tactile imaging

Thotegodage, DIU [Thesis-Full-text]

Tactile sensors are devices which acquire data from the physical world through sense of touch. These acquired data may be related to either, surface roughness, texture, force, or any other tactile parameter. Even though, ...
Numerical modeling of the flow field for indoor thermal comfort of a building under stack effect

Nimarshana, PHV [Thesis-Full-text]

In recent years natural ventilation is widely recognised as excellent contributing towards in design low energy buildings. The main challenge in natural ventilation is identified as lack of knowledge in providing acceptable ...
Development and clinical testing of a negative pressure wound therapy device

Welgama, WPD [Thesis-Abstract]

Negative Pressure Wound Therapy (NPWT) is a type of treatment in which suction is applied to a wound bed in combined with a specialized dressing to increase the wound healing rate. This study aims to develop a fully ...
Hybrid approach for financial forecasting with support vector machines

Roshan, WDS [Thesis-Full-text]

Financial markets are the biggest business platforms in the world. Therefore, financial forecasting is getting a lot of attention in today’s economic context. Accurate forecast is beneficial to broker firms, governments, ...
Evaluvating the potenital of adopting clean development mecahanism for implementing renewable energy based projects in Sri Lanka

Samarasinghe, JB [Thesis-Abstract]

Sri Lanka has had a hydropower dominated electricity generation for many years with relatively high rainfall mainly in the central hilly region. This factor has led to a greater dependence on hydropower for its power ...
Multi criterion decision making based on techno-economical optimization of stand-alone hybrid energy systems

Perera, ATD [Thesis-Abstract]

Hybrid Energy System (HES)s areincreasingly becoming popular for standalone electrification due to global concerns on GHG emissions and higher depletion of fossil fuel resources. Simultaneously research work on optimal ...
