Combined effects of treated domestic wastewater, fly ash, and calcium nitrite toward concrete sustainability
(
Elsevier
, 2021 , Article)
The drastic increase in freshwater and ordinary Portland cement (OPC) consumption poses severe environmental and economic challenges worldwide. This study; therefore, explores the mechanical and durability properties of ...
Thermal integrity testing of cast in situ piles: An alternative interpretation approach
(
SAGE Publications Ltd
, 2021 , Article)
Integrity testing of deep cast in situ concrete foundations is challenging due to the intrinsic nature of how these foundations are formed. Several integrity test methods have been developed and are well established, but ...
Piton: Investigating the Controllability of a Wearable Telexistence Robot
(
MDPI
, 2022 , Article)
The COVID-19 pandemic impacted collaborative activities, travel, and physical contact, increasing the demand for real-time interactions with remote environments. However, the existing remote communication solutions provide ...
Development and Implementation of Energy-Efficient Magnetorheological Fluid Bypass Damper for Prosthetics Limbs Using a Fuzzy-Logic Controller
(
Institute of Electrical and Electronics Engineers Inc.
, 2022 , Article)
Walking behaviour in amputees with lower-limb loss is absent from shock-absorbing properties. A damper can be used to reduce the impact of ground reaction force (GRF) during heel strikes. Magnetorheological fluid (MRF) ...
Smart City Applications: Promoting comfort, health and well-being through Sustainable Smart Urban Design (S2UD) in Msheireb Downtown
(
Institute of Electrical and Electronics Engineers Inc. (IEEE)
, 2020 , Conference Paper)
This study explores the Msheireb Downtown Project by studying the design qualities and adopted applications of its public open spaces (POS). We uncover their roles in the smart city design system with an eye for how they ...
A framework for the analysis of damage and recovery characteristics of asphalt mixtures
(
Taylor & Francis
, 2020 , Article)
This study presents two approaches for evaluating damage and recovery characteristics of asphalt mixtures. The first approach focuses on determining damage by extracting recoverable viscoelastic strain that has no damage ...
Forced vibration characteristics of embedded graphene oxide powder reinforced metal foam nanocomposite plate in thermal environment
(
Elsevier
, 2021 , Article)
Dynamic behavior of a new class of nanocomposites consisted of metal foam as matrix and graphene oxide powders as reinforcement is presented in this study in the framework of forced vibration. Graphene oxide powders are ...
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 ...
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. ...
