Investigation of energy storage options for sustainable energy systems.
(2013-08-01)Determination of the possible energy storage options for a specific source of energy requires a thorough analysis from the points of energy, exergy, and exergoeconomics. The main objective of this thesis is to investigate ... -
Experimental investigation and modeling of integrated tri-generation systems.
(2013-09-01)Energy demand in the world is increasing with population growth and higher living standards. Today, the need for energy requires a focus on renewable sources without abandoning fossil fuels. Efficient use of energy is one ... -
Thermal sustainability of low-temperature geothermal energy systems: System interactions and environmental impacts.
(2013-10-01)In storing heat during summer for use in winter, the ground provides a better source/sink of heat than the outside air in regards to heat pump efficiency, being cooler than the outside air in the summer and warmer in the ... -
Mass transfer and particle dissolution in liquid-gas and solid-liquid flows: Application to hydrogen production processes.
(2013-10-01)Many environmental problems are related to the production, transformation and use of energy. Some of the concerns include, but are not limited to, acid rain, ozone depletion and climate change. Therefore, “greener” ... -
Leadership based multi-objective optimization with applications in energy systems.
(2013-12-01)Multi-objective optimization metaheuristics (MOMs) are powerful methods for solving complex optimization problems but can require a large number of function evaluations to find optimal solutions. Thus, an efficient ... -
Design, analysis and experimental investigation of a new scroll expander based trigeneration system
(2014-01-01)Current technologies of using conventional energy produce a large amount of waste heat which can potentially be recovered in the form of useful work to use in our day to day life. This initiative not only optimizes the ... -
Asynchronous bi-directional relay-assisted communication networks
(2014-02-01)We consider an asynchronous bi-directional relay network, consisting of two singleantenna transceivers and multiple single-antenna relays, where the transceiver-relay paths are subject to different relaying and/or ... -
Designing power aware wireless sensor networks leveraging software modeling techniques
(2014-03-01)Wireless Sensor Networks (WSNs) are typically used to monitor specific phenomena and gather the data to a gateway node, where the data is further processed. WSNs nodes have limited power resources, which require developing ... -
Advances in parallel robotics for flexible and reconfigurable manufacturing
(2014-04-01)Parallel robotic manipulators are a specific type of robot that has multiple limbs which are ultimately connected to a moving body. Within this regime, there are several sub-classes of robots characterized by certain ... -
Design and characterization of next-generation tissue equivalent proportional counters for use in low energy neutron fields
(2014-04-01)Tissue Equivalent Proportional Counters (TEPCs) are devices that can measure the radiation dose levels for the mixed neutron and gamma ray fields that are encountered in nuclear facilities. TEPC designs typically consist ... -
Distributed policy-based management framework for wireless sensor networks.
(2014-06-01)Policy-Based Management Systems (PBMS) are becoming a critical component of any information technology environment, due to their ability to abstract hardware complexity from their users. Policy-based systems exist in such ... -
Development, analysis and performance assessment of net zero energy house systems.
(2014-08-01)Net zero energy buildings have captured the attention of many researchers and governments due to high energy consumption by traditional buildings. The design stage of a net zero energy house is the most crucial and cost ... -
A systems approach to assessing the sustainability of hybrid community energy systems.
(2014-09-01)The goal to achieve a sustainable society that will endure over the long term is generally regarded as a positive evolutionary course. One of the challenges with this goal is developing a quantitative assessment of the ... -
