This work presents two alternatives to optimize the performance of Rankine cycles. The first approach is focused on the spatial distribution of the areas used in the heat exchange process, and the second approach is intended to study the...
The Multiple Parabolic Reflector Flat Panel Collector (MPFC) was designed to heat a working fluid to a temperature of 150oC using the sun. The use of stationary reflectors and a moving receiver tube allow for maximum energy collection...
Autonomous ground vehicles (AGVs) are expected to be used extensively in unstructured, outdoor, undulating environments for tasks such as search and rescue, homeland security, fire fighting, reconnaissance, and surveillance. These tasks...
The rise in energy demand calls for rapid advancements in technology in terms of renewable energy. In doing so, to reduce the carbon emissions in the atmosphere and give the planet a fighting chance to battle global temperature rise....
Energy crises have been a major problem in Pakistan for many years. The country, which became independent in 1947, has struggled to meet the gap between the demand and supply of electricity. The electricity demand, as in most countries, ...
This dissertation presents a contribution to understanding the behavior of solar powered air conditioning and refrigeration systems with a view to determining the manner in which refrigeration rate; mass flows, heat transfer areas, and...
Global energy demands are on the rise, and the current technology used to generate, transmit, and distribute electricity will not be able to meet the growth due to the bottlenecks in densely populated areas and the inefficiencies...
Legged animals have long been shown to excel at maneuvering and navigating the complex and changing environments found in the natural world through a combination of highly actuated musculoskeletal structures, robust and flexible control...
Superconducting power devices require cable terminations to intercept the heat inleaks from the ambient temperature, thus, maintaining the superconducting cable within operating cryogenic temperature limits. Owing to the possible safety...
Carbon Nanotubes have been undergoing intensive research since their discovery in 1991. They have some excellent properties based on their unique chemical structure. The industry has been impatient to use them as reinforcement in various...
Materials for some industrial applications require that the processing do not result in recrystallization. Current method for inhibiting recrystallization involves the use of fine precipitates to pin the grain boundaries from migration....
Legged locomotion is advantageous on difficult natural terrains due to it only requiring discrete ground contacts. Biological systems with limbs have developed multiple levels of control to afford such fast and robust legged locomotion....
A dynamic three-dimensional volume element model (VEM) of a parabolic trough solar collector (PTC) comprising an outer glass cover, annular space, absorber tube, and heat transfer fluid is studied with detail. The model is coupled with...
Thermoelectric materials hold tremendous promise for advances in fundamental science and practical applications; particularly for robust electricity generation in extreme and remote environments. However, for most materials, the energy...
Catheter-based surgical procedures provide minimally invasive means to correct structural heartdisease (SHD). Endovascular procedures may require the use of two or more independently catheter-ized devices, such as an intracardiac...
