An Investigation into the Prevalence of Behavioral and Environmental determinants of cataract
( Qatar University Press , 2020 , Poster)Accounting for 51% of legal blindness in the world and 27% in Qatar,cataract remains the most prevelant cause of visual imapairments. Cataract involves the clouding of the eye lens, which reduces the light that reaches the ... -
AN INVESTIGATION OF THE IMPACT OF SOCIAL MEDIA MARKETING ACTIVITIES ON CONSUMERS PURCHASE INTENTION: EXAMINING THE ROLE OF BRAND EQUITY, RELATIONSHIP EQUITY, AND BRAND TRUST IN S-COMMERCE
(2022 , Master Thesis)This research addresses the great need to explore the different impacts of social media marketing activities on consumers' purchase intention in s-commerce in Qatar, which is less represented in the literature. Accordingly, ... -
An Investigation of the Swelling Kinetics of Bentonite Systems Using Particle Size Analysis
( Taylor and Francis Inc. , 2019 , Article)Particles size distribution (PSD) is introduced as a tool for analysis of bentonite aggregation and swelling kinetics. Raw Ca-bentonite was purified using a combined wet sieving and sedimentation processes, followed by ... -
An investigation to study the effects of Tai Chi on human gait dynamics using classical machine learning
( Elsevier , 2022 , Article)Tai Chi has been proven effective in preventing falls in older adults, improving the joint function of knee osteoarthritis patients, and improving the balance of stroke survivors. However, the effect of Tai Chi on human ... -
An IoT-Based Framework for Elderly Remote Monitoring
( Institute of Electrical and Electronics Engineers Inc. , 2019 , Conference Paper)This Paper presents an Internet of Things (IoT) based framework to monitor ECG for biometric recognition and acceleration for fall detection.
