Neighbourhood oriented TDMA scheme for the internet of things-enabled remote sensing
(
Taylor and Francis Ltd.
, 2023 , Article)
Throughout the world, Internet of Things (IoT) have been used in different application areas to assist human beings in numerous activities such as smart buildings and cities via remote sensing-enabled techniques. However, ...
Academic self-concept and its relationship to academic achievement among university students.
(2022 , Article)
This research sought to study the academic self-concept and the relationship between the academic self-concept and students’ academic achievement among university Qatari students. Research of the academic self-concept is ...
Microstructure and mechanical behavior of hot extruded aluminum/tin-bismuth composites produced by powder metallurgy
(
MDPI AG
, 2020 , Article)
In this study, Al-BiSn composites were synthesized by a combination of microwave sintering and hot extrusion processes. The structural, morphological, mechanical, and thermal properties were investigated to elucidate the ...
Combined direct oxy-combustion and concentrated solar supercritical carbon dioxide power system—Thermo, exergoeconomic, and quadruple optimization analyses
(
Hindawi
, 2022 , Article)
For the global future energy systems, concentrated solar power (CSP) and direct CO2 capture systems are of the most important key technologies, however, each of these systems has shortcomings. This study addresses the solar ...
The Impact of ACE Gene Variants on Acute-Phase Reactants in Children with Rheumatic Heart Disease
(
MDPI
, 2023 , Article)
Rheumatic heart disease (RHD) is the most important sequela of upper respiratory group A Streptococcus (GAS) infection. The role of the common angiotensin-converting enzyme (ACE) insertion/deletion (I/D) variant in the ...
Dorm augmented college assignments
(
Springer Science and Business Media Deutschland GmbH
, 2024 , Article)
In college assignments, a common practice is that students receive their dorm allocation after the realization of college placements. This causes wasted resources and unfair allocation. To fix this, we consider a college ...
A hybrid piezoelectric-electromagnetic energy harvester from vortex-induced vibrations in fluid-flow; the influence of boundary condition in tuning the harvester
(
Elsevier
, 2022 , Article)
In this paper, a hybrid piezoelectric-electromagnetic energy harvester is proposed to harvest energy from fluid flow around a bluff-body using vortex-induced vibration (VIV). The hybrid piezoelectric-electromagnetic harvester ...
Adaptive Electromagnetic Vibration Absorber for a Multimode Structure
(
Assoc. of Mechanical Eng. and Technicians of Slovenia
, 2022 , Article)
All structures experience vibrations due to external dynamic force excitations, such as earthquakes and wind loadings. At resonance, the impact of this natural dynamic force on structures may lead to structural failures. ...
Energy harvesting from railway slab-tracks with continuous slabs
(
SAGE Publications Inc.
, 2023 , Article)
This paper contributes to the literature and development of knowledge in the topic of energy harvesting by presenting the modelling and calculations of energy from vibration of railway tracks due to moving trains on ...
Magnetorheological elastomer-based variable stiffness flexible coupling for vibration isolation
(
Canadian Science Publishing
, 2021 , Article)
Rotating mechanical equipment such as pumps and motors can suffer from unattenuated torsional vibration. The causes of such vibration range from imbalance within the rotating system to misalignment, or even operating at ...
