IMAGING BIOMARKERS FOR NEURODEGENERATION IN OBESITY: A CROSS-SECTIONAL STUDY

BARAKA, AREEJ KHALED ABDELKARIM

Background: Obesity is associated with peripheral neuropathy and microvascular alterations, even without diabetes. Current techniques to assess peripheral neuropathy include assessment of symptoms, which identify a small subset of patients with neuropathy and neurological examination, quantitative sensory testing (QST)...

DEEP NEURAL NETWORKS WITH MULTIPLE OUTPUT LAYERS

MOHAMED, MOHAMED HAMDY MOHAMED ABDELHAFEZ

Deep neural networks derive their strength from hierarchical representation learning, yet conventional training paradigms typically inject supervision only at the final layer, leaving intermediate representations underutilized during both learning and inference. This thesis investigates how intermediate representations...

DETECTING POLICY-PREFERENCE CONTRADICTIONS IN PRIVACY POLICIES

MALLUHI, RAZAN

Privacy policies are intended to inform users about how their data is collected and used, yet they remain lengthy, complex, and rarely read. While automated policy analysis tools have improved the extraction of data practices, they do not systematically detect contradictions between policy statements and individual use...

EVALUATION OF PROTON PUMP INHIBITORS PRESCRIBING, LONG-TERM USE, AND ASSOCIATED ADVERSE DRUG REACTIONS

IBRAHIM, ASMAA ADEL BADRELDIN BADRELDIN

Background: Proton pump inhibitors (PPIs) are widely prescribed for acid-related disorders. However, inappropriate use of PPIs and prolonged therapy are associated with an increased risk of adverse drug reactions (ADRs). Evidence regarding the burden of PPI-induced ADRs and their clinical predictors in Qatar remains li...

ENHANCING MULTIMODAL MEME CONTENT MODERATION WITH REINFORCEMENT LEARNING

KMAINASI, MOHAMED BAYAN EMAD

Hateful and propagandistic memes require joint reasoning over image and text, since neither modality alone may reveal harmful intent. Thinking-based multimodal large language models (MLLMs) and reinforcement-learning post-training have not yet been combined for meme moderation. We close this gap with a thinking-based M...

HIERARCHICAL POROUS ONE-DIMENSIONAL NANOCARBONS CONFINED NONMETAL HETEROATOMS AS EFFICIENT CATHODES FOR GREEN HYDROGEN PRODUCTION

HUBAISH, SYED MOHAMMED

The intolerable-cost of hydrogen evolution reaction (HER) is a great barrier, so metal-free catalysts emerged as potential solutions, but their activities are inferior besides complexity of preparation. Herein we synthesize carbon nanoflakes derived from carbon cloth doped with boron-atoms (Bx/C), (x= 3.42, 5.04, 9.79,...

ASSOCIATION BETWEEN CIRCADIAN SYNDROME AND ASTHMA AMONG ADULTS: EVIDENCE FROM CHINA, USA, AND UK

LATHIEF, SHALIMA KATTAPARAMBU MOHAMED

Circadian dysfunction has been linked to respiratory diseases, yet its association with asthma remains unclear. This study examined the association between circadian syndrome (CircS) and asthma and evaluated whether CircS is a stronger predictor of asthma than meta-bolic syndrome (MetS). Data from the United States (Na...

SYNTHESIZING SILICON QUANTUM DOTS (SIQDS) FROM FOOD WASTE AS GREEN EFFICIENT SCALE INHIBITORS

PIRES, ADILLA AMIRO

This work presents the development of sustainable, high-performance nanomaterials for oilfield scale management through the synthesis and functionalization of silicon quantum dots (SiQDs) derived from biomass precursors. The study addresses key limitations of conventional scale inhibitors, including environmental toxic...

VULCAN: A HYBRID CNN–TRANSFORMER FUSION MODEL WITH FEDERATED LEARNING FOR VISION-BASED FIRE AND SMOKE DETECTION

ALSHAMMARI, HAYA M KH

Early fire and smoke detection is critical for protecting lives and infrastructure. While vision-based deep learning methods outperform traditional sensors, they lack principled fusion strategies and remain underexplored in privacy-preserving, distributed settings. This thesis presents two contributions. First, it prop...

ELECTROCHEMICAL TREATMENT OF 4-CHLOROPHENOL USING MIXED METAL OXIDE CATALYSTS

ASHOK, AROMAL

The presence of chlorinated organic pollutants in industrial wastewater poses serious environmental and health risks due to their toxicity and persistence. This thesis investigates the electrochemical degradation of 4-chlorophenol (4-CP) using mixed metal oxide catalysts. The study originated from a review on disinfect...
