MODEL-BASED DIAGNOSTICS OF SIMULTANEOUS TOOTH CRACKS IN SPUR GEARS
(Mechanical Engineering, 2017 , Master Thesis)
This study aims at developing a numerical model that could be used to simulate the effect of tooth cracks on the vibration behavior of spur gears. Gears are a key component that is widely used in various rotating equipment ...
Semi-Active Vibration Isolator Using Magnetorheological Elastomer (MRE)
(Mechanical Engineering, 2020 , Master Thesis)
Smart materials are materials by which their properties are able to be altered due to external stimuli such as temperature, pressure and magnetic field. Magnetorheological Elastomer (MRE) is a type of smart composite ...
DEVELOPMENT OF HYBRID AND NON-HYBRID COMPOSITE BODY ARMOR PLATE FOR BALLISTIC PROTECTION
(Mechanical Engineering, 2017 , Master Thesis)
In this work, a new Bullet Guiding Pocket Armor Plate (BGPAP) was developed, with a target to maximize the ballistic protection by containing the bullet between the layers. To this end, experimental and numerical programs ...
MODELLING OF WHIPLASH TRAUMA; PARAMETRIC STUDY OF REAR-END COLLISION AND DEVELOPMENT OF HEAD-RESTRAINT SYSTEM
(Mechanical Engineering, 2017 , Master Thesis)
Whiplash is a common neck injury people usually suffer from after a rear car accident. Over the past decade, both engineers and physicians were trying to analyze the biomechanics of the injury to develop an effective ...
Concentrated Solar Power Plant for Key Locations in Doha Qatar
(Engineering-Mechanical Engineering, 2017 , Master Thesis)
One of the pillars of the Qatar National Vision 2030 is the protection and preservation of the environment by decreasing the dependency on hydrocarbon resources and promoting the use and development of renewable energy ...
INVESTIGATION OF LAMINAR FLAME SPEED OF ALTERNATIVE LIQUID FUEL BLENDS
(Mechanical Engineering, 2016 , Master Thesis)
The rapid fluctuation in oil prices and increased demand of clean fuels to reduce
emissions has forced the researchers to find alternative fuels that can give the same
or better overall fuel characteristics. This thesis ...
COLLAPSE BEHAVIOR AND ENERGY ABSORPTION OF CORRUGATED TAPERED TUBES
(Mechanical Engineering, 2018 , Master Thesis)
Thin-walled structures have been widely used in energy absorption and safety applications such as automotive vehicles and locomotives, due to their lightweight, progressive folding modes, and reduced manufacturing costs. ...
COMBUSTION CHARACTERISTICS AND EMISSION OF A DI DIESEL ENGINE UTILIZING NEW INDUCTION MANIFOLD DESIGNS AND RUNNING ON ALTERNATIVE FUEL BLENDS
(Mechanical Engineering, 2018 , Master Thesis)
The demands for increasing the swirl in the combustion chamber and for decreasing the exhaust emissions on diesel engines have increased rapidly over the past few years. Consequently, the researchers’ attention has been ...
EXPERIMENTAL DETECTION OF LOCALIZED SURFACE DEFECTS IN BALL BEARINGS USING VIBRATION ANALYSIS
(Mechanical Engineering, 2018 , Master Thesis)
Experimental Detection of Localized Surface Defects in Ball Bearings Using Vibration Analysis
Bearings play a crucial role in the functioning of rotating machinery. Any failure
of this critical component may cause severe ...
NEW APPROACH OF PIPELINES JOINING USING FIBER REINFORCED PLASTICS COMPOSITES
(Mechanical Engineering, 2018 , Master Thesis)
It is well known that maintenance of pipelines failures due to leakage or rupture caused by either corrosion or lack of strength is a significant challenge for pipelines engineers. Pipelines joining is considered as a ...
