NITROGEN AND SULFUR– DOPED CARBON NANOFIBER MIXED OXIDES COMPOSITES FOR SUPERCAPACITOR APPLICATIONS
(2016 , Master Thesis)Energy storage devices including supercapacitor are among the rapidly growing field of alternatives for rechargeable batteries due to its high energy density and long life cyclability performance. Electrospinning is a ... -
A NON-DESTRUCTIVE METHODOLOGY FOR LEAK DETECTION IN WATER NETWORKS USING INFRARED PHOTOGRAPHY (IR) AND GROUND PENETRATING RADAR (GPR)
(2016 , Master Thesis)Two noninvasive and nondestructive methodologies for detecting leaks in water pipes were proposed and tested. The first method combines the use of Ground Penetrating Radar (GPR) for accurate determination of pipe location, ... -
NON-DETERMINISTIC MODELING USING QUANTILE REGRESSION
(06-2 , Master Thesis)In this thesis, we utilize quantile regression to model the conditional quantile of the dependent variable given independent variables to capture more details about the conditional distribution. In addition, we apply the ... -
NONSYNDROMIC HEARING LOSS IN QATAR: THE GENETIC BASIS AND THE DIAGNOSTIC YIELD OF GENETIC TESTING
(2022 , Professional Masters Project)Background: Hearing loss is the most predominant sensory defect worldwide with around 8% of cases occurring in children. Approximately 66% of childhood-onset hearing loss cases are attributed to genetic factors. The ... -
Northeastern Qatari coast hydrodynamic modeling for assessment of sensitive ecosystems under anthropogenic and natural stressors
(2015 , Master Thesis)The Northeastern Qatari coast, comprising diverse and sensitive flora and fauna communities (e.g. coral reefs and patches, seagrass meadows and turtles) is expected to undergo changes imposed by anthropogenic stressors ... -
Novel Adsorbents For The Removal Of Oil From Produced Water
(2019 , Master Thesis)Produced water is water that is brought up to the surface of the well during oil and gas operations. Almost all oil and gas wells generate huge amounts of produced water as part of the production process. These large volumes ... -
Novel approach in treating industrial wastewater using metal-organic framework nanoparticles impregnated with biosurfactants.
(2024 , Dissertation)Arabian Gulf countries including Qatar are amongst the main oil and gas (O&G) producers globally. A huge amount of water is used during the upstream and downstream processes of oil and gas refiners. As a result, a large ... -
A Novel Electrocoagulation System For Produced Water Treatment
(2018 , Master Thesis)Produced water, which is generated from the Oil & Gas industries, is becoming a global concern due to its complex composition and large volumes. This thesis introduces a novel electrocoagulation system for the treatment ... -
A Novel Framework For Construction Contractor Selection Using Unique Hybrid Multi-Criteria Decision-Making Technique
(2018 , Master Thesis)The successful delivery of a construction project is highly dependent on the contractor allocated to the project and hence the proper selection of the contractor is of significant importance. In public sector, the procurement ... -
A NOVEL HYBRID ELECTRO-COAGULATION/ FORWARD OSMOSIS MEMBRANE SYSTEM FOR TREATMENT OF PRODUCED WATER
(2018 , Master Thesis)Large volumes of fresh water are consumed in the process of oil and gas exploration, producing even larger volumes of highly contaminated produced water (PW) which exhibits a major environmental problem. This work ... -
Novel Process for Designing Topology Optimized Femoral Stems Printable by Metal Additive Manufacturing
(2019 , Master Thesis)Total hip arthroplasty faces an issue of the high cost and risks of revision surgeries. Studies show that more than 50% of the revision surgeries are the consequence of the aseptic loosening of the implant. The cause ... -
The Novel Role of BRIP1 in Breast Tumor Development and Progression
(2020 , Dissertation)Breast cancer (BC) is the most common malignancy and the leading cause of death in women worldwide. Only 5-10% of mutations in the BRCA genes are attributed to familial breast tumors in Eastern countries, suggesting the ... -
Novel Techniques for Blockchain-enabled IoT Systems Leveraging Reinforcement Learning
