Incorporation of Nitrogen and Nano-diamonds into Diamond-Like Carbon Coatings on Ti-6Al-4V for Enhancement of Wear and Corrosion Resistance
(2016-08-05)
Titanium and its alloys are widely used for industrial applications. However, extended use of titanium in some applications has been severely limited due to its poor surface properties. Diamond-like carbon (DLC), which is ...
A NOVEL TRANSIENT TESTING METHOD FOR HEAT/ENERGY WHEEL COMPONENTS
(2016-07-28)
Heat wheels and energy wheels are widely used in ventilation systems to recovery sensible and latent energy, and consequently, reduce the energy required to condition outdoor ventilation air for buildings. This Ph.D. thesis ...
AUSTENITIC STAINLESS STEELS FOR FUTURE NUCLEAR FUEL CLADDINGS
(2016-09-27)
Nuclear power systems have been under continuous development since the first nuclear power plant started operation in 1954. They are categorized into different generations, with each new generation having significant ...
An experimental study of a plane turbulent wall jet on smooth and rough surfaces
(2016-05-20)
This study presents an experimental investigation of incomplete similarity and the effect of surface roughness on a plane turbulent wall jet on a hydraulically smooth, transitionally rough and fully rough surface based on ...
Towards a new approach for enterprise integration : the semantic modeling approach
(2003-05-10)
Manufacturing today has become a matter of the effective and efficient application of information technology and knowledge engineering. Manufacturing firms’ success depends to a great extent on information technology, which ...
Mechanics and FEM simulation of active vibration control in structural systems by using internal mass reconfiguration
(2011-09-27)
Relative motion of different parts of a structure can affect its vibrations that may be amplified
or attenuated. If such a motion is properly devised, it can lead to continuous attenuation of
vibration and thus be used for ...
ADIABATIC SHEAR LOCALIZATION IN AISI 1340 AND 4340 STEELS: THE INFLUENCE OF MICROSTRUCTURE AND GEOMETRY
(2011-10-17)
The mechanical behaviour of AISI 1340 and 4340 steel under high strain-rate loading in compression and in torsion were investigated using direct impact Hopkinson bar and torsion split Hopkinson bars. Both alloys contained ...
Damage Evolution in AA2099 and AA6061 Aluminum Alloys Under Quasi-static and Dynamic Mechanical Loading
(2011-09-22)
In this research, the behavior of AA2099 and AA6061 aluminum alloys under quasi-static and dynamic mechanical loading conditions was examined. The effects of temper condition on the dynamic response of both alloys were ...
Development of a simulation model of a backhoe excavator
(2011-09-29)
The recent pattern of record-high fuel prices has motivated a trend towards reducing the fuel consumption of today’s equipment, while still maintaining the capability and performance offered in previous models. One ...
Measurement of Axial Induction Factor for a Model Wind Turbine
(2012-08-30)
Understanding the velocity field information near the rotor plane of a wind turbine at various operating conditions is very important to understanding the aerodynamic performance of the wind turbine. Investigation of these ...
