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. To this end, an-IoT based Remote Elderly Monitoring System (REMS) platform is ... -
An IoT-based framework for remote fall monitoring
( Elsevier , 2021 , Article)Fall detection is a serious healthcare issue that needs to be solved. Falling without quick medical intervention would lower elderly's chances of survival, especially if living alone. Hence, the need is there for developing ... -
An Islamic view towards sustainability: The theory and practice of GCC countries
( Hamad bin Khalifa University Press (HBKU Press) , 2016 , Conference Paper)Despite the fact that many public policy issues related to sustainability are usually framed in the form of government initiatives and programs, probably an equally, if not more, important topic, is how to change people's ... -
An iterative method for common solution to various problems
( Jangjeon Mathematical Society , 2019 , Article)In this paper, we introduce a new iterative method to find a common solution of a generalized mixed equilibrium problem, a variational inequality problem and a hierarchical fixed point problem for demicontinuous nearly ... -
An IV-SVM-based approach for identification of state-space LPV models under generic noise conditions
( Institute of Electrical and Electronics Engineers Inc. , 2015 , Conference Paper)This paper presents a nonparametric identification method for state-space linear parameter-varying (LPV) models using a modified support vector machine (SVM) approach. While most LPV identification schemes in the state-space ... -
An LCL filter-based grid-interfaced three-phase voltage source inverter: Performance evaluation and stability analysis
( Institution of Engineering and Technology , 2014 , Conference Paper)Power converters in grid connection applications commonly employ Sinusoidal Pulse-Width Modulation (SPWM) technique. Passive filters are employed in order to attenuate the generated switching current ripples and reduces ... -
