A hybrid absorption/thermo-electric cooling system driven by a concentrated photovoltaic/thermal unit
( Elsevier , 2020 , Article)This paper presents a novel hybrid solar cooling system driven by a concentrated photovoltaic/thermal unit (CPV/T). The electricity of the PV module is used to power the thermoelectric cooler while the thermal energy is ... -
A new oscillator with mega-stability and its Hamilton energy: Infinite coexisting hidden and self-excited attractors
( American Institute of Physics Inc. , 2020 , Article)In this paper, we introduce an interesting new megastable oscillator with infinite coexisting hidden and self-excited attractors (generated by stable fixed points and unstable ones), which are fixed points and limit cycles ... -
A decision-making analysis in UAV-enabled wireless power transfer for IoT networks
( Elsevier , 2020 , Article)We consider an IoT network with energy-harvesting capabilities. To extend the network lifetime, we propose a novel unmanned aerial vehicle (UAV)- enabled wireless power transfer (WPT) system, where UAVs move among IoT ... -
A comparison study of trust in m-commerce between qatari and non-qatari customers
( Springer Science and Business Media Deutschland GmbH , 2020 , Conference)Over the past few years, mobile commerce (M-commerce), which is a new channel for conducting online businesses has revolutionized the global market. In Qatar, due to lack of trust, an only small percentage of Qatari ... -
A Review of Sustainable Consumption (2000 to 2020): What We Know and What We Need to Know
( Routledge , 2020 , Article)Owing to environmental pollution and care for natural resources, the notion of sustainable consumption has gained significant research attention. However, studies on sustainable consumption are still in their infancy and ... -
Age could be driving variable SARS-CoV-2 epidemic trajectories worldwide
( Public Library of Science , 2020 , Article)Current geographic spread of documented severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections shows heterogeneity. This study explores the role of age in potentially driving differentials in infection ... -
A Novel Differential Evolution Algorithm with Q-Learning for Economical and Statistical Design of X-Bar Control Charts
( Institute of Electrical and Electronics Engineers Inc. , 2020 , Conference)This paper presents a novel differential evolution algorithm with Q-Learning (DE_QL) for the economical and statistical design of X-Bar control charts, which has been commonly used in industry to control manufacturing ... -
A novel hybrid secure image encryption based on Julia set of fractals and 3D lorenz chaotic map
( MDPI , 2020 , Article)Chaos-based encryption schemes have attracted many researchers around the world in the digital image security domain. Digital images can be secured using existing chaotic maps, multiple chaotic maps, and several other ... -
A low-latency and energy-efficient neighbor discovery algorithm for wireless sensor networks
( MDPI , 2020 , Article)Wireless sensor networks have been widely adopted, and neighbor discovery is an essential step to construct the networks. Most existing studies on neighbor discovery are designed on the assumption that either all nodes are ... -
A novel video-vibration monitoring system for walking pattern identification on floors
( Elsevier , 2020 , Article)Walking-induced loads on office floors can generate unwanted vibrations. The current multi-person loading models are limited since they do not take into account nondeterministic factors such as pacing rates, walking paths, ... -
A comparative study of the incorporation effect of SWCNT-OH and DWCNT with varied microstructural defects on tensile and impact strengths of epoxy based nanocomposite
( Springer , 2020 , Article)This study presents an investigation of the influence of Single-Walled Carbon Nanotubes (SWCNTs) and Double-Walled Carbon Nanotubes (DWCNTs) on tensile and impact strengths of epoxy based nanocomposites. Two different CNTs ... -
A novel test method for tendon re-anchorage in bonded post tensioned concrete using ESPI full field measurement
