The results of a study into the development of novel Thermoelectric (TE) materials by engineering nanoscale constrictions are presented in this thesis. The aim of this investigation lies in the development of an enhanced ...
Manual handling is an indispensable activity in any occupational setting. It is any activity that requires the use of human force for lifting, carrying or moving an object. Such repetitive and tiring tasks may cause ...
Manufacturing organizations are using a considerable amount of energy for their daily manufacturing operations and more than 60% of their total energy use is for thermal applications. Therefore, systems that use thermal ...
Over the past few years, positive changes have occurred in the manufacturing industry and many other fields as a direct result of current breakthroughs in nanotechnology. The integration of nano-sized solid lubricants into ...
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 ...
Wearable exosuits require flexible, linearly contractile, and lightweight actuators to
provide sufficient force to move the respective limb. This thesis presents the concept,
design, fabrication, experimental performance ...
Food packaging plays a vital role in human existence by eliminating barriers to satisfying food
requirements regardless of geography. Since food is a basic requirement of all human beings, a
billion-dollar industry has ...
An analysis of global, beam and diffuse solar radiation on horizontal and 7° tilt about east west axis and facing due south orientation at Hambanthota was carried out to assess the solar resource potential in dry zone of ...
Solar photovoltaic (PV) is penetrating electrical grids with a substantial growth of new additions, as a result of renewable energy policies and plans implemented locally and globally. However, the intermittent nature of ...
Open sun drying is the widely used passive method for black pepper drying, but due to its
limitations such as unavailability on rainy days, lack of controllability, degradation of food
quality, loss of volatile oil, and ...
Microfluidics has recently gained research attention for its high-end thermal
applications, including micro heat exchangers, Lab on a Chip, micro reactors, and
MEMS. It has been proven that the addition of suitable ...
This work relates to the design and development of Shape Memory Alloy (SMA) based novel
actuators for Minimally Invasive Surgeries (MIS). Compared to conventional open surgery,
MIS procedures are favorable and developments ...
In the beginning, humans used architecture to protect their selves from nature and unsteady
environmental conditions. However, with time, modern buildings become more complex,
which need to fulfil the different types of ...
Physical phenomenon of the relation among ground-level ozone (O

Diffused shaped holes have shown superior cooling performance over the other shapes
of holes in many situations. In the present study, numerical simulation using realizable
k-ε model with enhanced wall treatments as ...
The wellbeing, comfort, and satisfaction of office occupants are all influenced by the
indoor air quality (IAQ). As such, it is important to maintain good IAQ in offices.
However, several studies say that Sri Lankans ...
Buildings are responsible for about 40% of global energy consumption, 42% of global CO2 emissions and about 30% of global fresh water consumption. Therefore, the importance of energy and water consumption benchmarking in ...
Sri Lanka is a developing country, where wastewater and septic disposal are not managed at
its optimum level. 76% percent of the households equip with their own water sealed latrines
for sanitation facilities and discharged ...
The manufacturing industry largely contributes to the economy of a country. Thus,
manufacturing by material removal processes leaves a significant environmental footprint.
This is caused by the influence of process energy, ...
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 ...
