A reliability-aware framework for service-based software development
(2017-01-01)
It is becoming common to see software applications taking advantage of web services available publicly to meet their needs, rather than developing an in-house solution. This introduces the problem where failures can occur ...
Design and development of a custom dual fuel (hydrogen and gasoline) power system for an extended range electric vehicle architecture
(2009-06-01)
In recent decades there has been a growing global concern with regards to vehicle-generated
green house gas (GHG) emissions and the resulting air pollution. Currently, gasoline and diesel
are the most widely used automotive ...
Achieving high efficiency thermoelectric heating and cooling with metal foam heat exchangers
(2014-04-01)
This thesis examines the development of a high efficiency heat pump system using
thermoelectric (TE) and reticulated metal foam (RMF) technologies to power a vehicle`s
battery thermal management system. The focus is split ...
Energy, exergy and exergoeconomic analyses of gas-turbine based systems
(2011-12-01)
Gas turbines are the primary technology used for the purpose of power generation nearly everywhere. In this thesis, the Makkah Power Plant, running on a Brayton cycle, is considered for analysis. The peak demand for electric ...
Vibration suppression of straight and curved beams traversed by moving loads
(2011-09-01)
Vibration suppression of beams traversed by moving loads, using optimal Tuned-Mass-Damper (TMD) systems, is investigated. This study is performed on two different geometrical shapes of the beam, namely, uniform homogenous ...
Modeling of voltage source converter based HVDC transmission system in EMTP-RV
(2010-08-01)
Voltage Source Converter (VSC) applications include but are not limited to HVDC, Flexible AC Transmission System (FACTS) devices such as STATCOM, SSSC, UPFC and Wind generators and active filters. The VSC based HVDC system ...
Energy-efficient relay cooperation for lifetime maximization
(2011-08-01)
We study energy-efficient power allocation among relays for lifetime maximization
in a dual-hop relay network operated by amplify-and-forward relays with battery
limitations. Power allocation algorithms are proposed for ...
Improved design of three-degree of freedom hip exoskeleton based on biomimetic parallel structure
(2011-07-01)
The external skeletons, Exoskeletons, are not a new research area in this highly
developed world. They are widely used in helping the wearer to enhance human strength,
endurance, and speed while walking with them. Most ...
Forensic analysis of unallocated space
(2011-06-01)
Computer forensics has become an important technology in providing evidence in investigations of computer misuse, attacks against computer systems and more traditional crimes like money laundering and fraud where digital ...
Interactive visualization of the collaborative research network
(2012-01-01)
Social networks have been evolving over the past few years, leading to a rapid increase in the number and complexity of relationships among their entities. In this research, we focus on a large scale dataset known as the ...
