Experimental detection of localized surface defects in ball bearings using vibration analysis
(
Canadian Acoustical Association
, 2019 , Conference Paper)
This study aimed at the monitoring of bearing health condition, based on vibration measurement. For that purpose, small circular defects were seeded on outer and inner rings of similar bearings, by using the principle of ...
PREDICTING ROAD ROUGHNESS PROFILE USING DYNAMIC VEHICLE ACCELERATIONS AND ARTIFICIAL NEURAL NETWORKS
(
Society of Acoustics
, 2022 , Conference Paper)
Road roughness can cause ride discomfort and contribute to the emission of ground-borne noise and vibration. A robust monitoring regime of road roughness is essential for the efficient maintenance of a country's road ...
Active control of noise in ventilation ducts
(
Canadian Acoustical Association
, 2019 , Conference Paper)
Ventilation ducts are often lined with passive absorption material for both thermal insulation and noise and vibration reduction. However, the noise reduction performance is not significant at low frequencies. Active Noise ...
A weight-management camp followed by weekly after-school lifestyle education sessions as an obesity intervention for Qatari children: a prospective cohort study
(
Elsevier
, 2015 , Conference Paper)
Background Weight-management camp interventions for obese children are eff ective for short-term weight loss. However, there is little evidence indicating how gains made with such interventions can be maintained in the ...
Blockchain technology for healthcare: Enhancing shared electronic health record interoperability and integrity
(
Institute of Electrical and Electronics Engineers Inc.
, 2020 , Conference Paper)
The Electronic Health Records (EHR) sharing system is the state of art for delivering healthcare. The tools within the system can predict outcomes during the patient's lifetime, monitor how effective are treatments, track ...
Towards commercialization of self-healing technology in epoxy coatings
(
National Assoc. of Corrosion Engineers International
, 2015 , Conference Paper)
This work is focused on developing viable self-healing coatings especially considering the viability of the coating in a commercial context. With this in mind, finding low cost healing agents, with satisfactory healing and ...
Degraded Arid Soil Reclamation for Cotton Cultivation Using Organic Waste Amendments
(2024 , Conference Paper)
Qatar is one of the most fertilizer-dependent countries due to challenging soil and climatic conditions. The country strives toward self-sufficiency in agricultural production in alignment with the Qatar National Vision ...
Numerical study on settlement of piled foundations on homogenous rock
(
Taylor and Francis
, 2014 , Conference Paper)
Settlement behavior of piled foundations on homogenous rock was investigated using an extensive three-dimensional finite element analysis of different piled-foundation models. Effects of pile slenderness ratio, pile spacing, ...
Laboratory testing of full-scale pipes partially embedded in soil to study soil-pipe interaction of offshore seabed oil and gas pipelines - Initial observations
(
American Society of Mechanical Engineers (ASME)
, 2014 , Conference Paper)
The geotechnical aspect of the design of off-shore oil and gas pipelines is a challenge due to inherent uncertainties in predicting soil-pipe interaction behaviour. Physical modeling is often sought after to gain insight ...
Geotechnical considerations on the design of piled rafts on rock
(
Research Publishing Services
, 2011 , Conference Paper)
This research shows the effect of misestimating the pile spring constant (Kpl) and the modulus of subgrade reaction (Ksg) on design of piled rafts on rock. The high mass stiffness of rock contacting the base of such rafts ...
