System approach for building energy conservation
(
Elsevier
, 2014 , Conference Paper)
Energy use in residential and commercial buildings and towers represents more than 30% of energy consumption. The increase in number of buildings and towers in most of the major cities worldwide led to several initiatives ...
New vehicle bumper design for pedestrian protection during impact
(
Institute of Physics Publishing
, 2015 , Conference Paper)
This study discusses the influence of the active bumper design on the performance of the selected current bumper in terms of pedestrian protection by using finite element method. The legform impactor is used to test the ...
Numerical simulation of a novel expanded metal tubular structure for crashworthiness application
(
Institute of Physics Publishing
, 2015 , Conference Paper)
Search for new geometries and materials that would serve in crashworthiness applications is a cumulative process. Recent studies investigated the performance of expanded metal tubes and the possible ways to enhance its ...
A comparative analysis of experimental and numerical investigations of composite tubes under axial and lateral loading
(2010 , Article)
Quasi-static tests are performed in order to determine the crash behavior of composite tubes. The specimens are made from woven fiber carbon/epoxy. The crash experiments show that the tubes crushed in a progressive manner ...
Mechanical and Thermal Analysis of Classical Functionally Graded Coated Beam
(
EDP Sciences
, 2018 , Conference Paper)
The governing equation of a classical rectangular coated beam made of two layers subjected to thermal and uniformly distributed mechanical loads are derived by using the principle of virtual displacements and based on ...
A Robust Channel Estimation Scheme for 5G Massive MIMO Systems
(
Hindawi Limited
, 2019 , Article)
Channel state information (CSI) feedback in massive MIMO systems is too large due to large pilot overhead. It is due to the large channel matrix dimension which depends on the number of base station (BS) antennas and ...
Structure and Rheological Properties of Bovine Aortic Heart Valve and Pericardium Tissue: Implications in Bioprosthetic and Tissue-Engineered Heart Valves
(
Hindawi Limited
, 2019 , Article)
Heart valve (HV) diseases are among the leading causes of cardiac failure and deaths. Of the various HV diseases, damaged HV leaflets are among the primary culprits. In many cases, impaired HV restoration is not always ...
Computational Simulation Of Organic Rankine Cycle Retrofitted To Petroleum Well
(
Hamad bin Khalifa University Press (HBKU Press)
, 2014 , Conference Paper)
Geothermal refers to existing heat energy in deep rock and sedimentary basins. Unlike other types of renewable energy resources, geothermal energy provides a stable source of energy as it can be exploited regardless of ...
Potential of geothermal energy for electricity generation in Qatar
(
Canadian Institute of Mining, Metallurgy and Petroleum
, 2013 , Conference Paper)
There is general acceptance that climate change, which is the most important challenge facing humanity, is anthropogenic and attributed to fossil fuel consumption. Therefore, improving the performance of our existing energy ...
On the aero acoustic and internal flows structure in a centrifugal compressor with hub side cavity operating at off design condition
(
Elsevier
, 2016 , Article)
This paper covers the characterization of the acoustic noise and the unsteady flow field of a high speed centrifugal compressor NASA CC3. In order to accurately predict the noise, all analyses are carried out through the ...
