Thermoeconomic and optimization analyses of direct oxy-combustion supercritical carbon dioxide power cycles with dry and wet cooling
(
Elsevier
, 2021 , Article)
Oxy-combustion supercritical CO2 power cycles have the advantages of high-energy efficiency and near-zero pollutant emissions. Thus, these cycles are considered as an efficient way to reduce CO2 emissions while maintaining ...
Energy and exergy analyses of novel supercritical CO2 Brayton cycles driven by direct oxy-fuel combustor
(
Elsevier
, 2021 , Article)
This study addresses major research gaps related to supercritical carbon dioxide (sCO2) power cycles including the shortcomings due to adding extra components, the high operating temperatures and the lack of studies on ...
Rupture of an industrial gfrp composite mitered elbow pipe
(
MDPI AG
, 2021 , Article)
This paper examines the immature rupture of glass fiber reinforced plastic composite (GFRP) mitered elbow pipes. The GFRP composite mitered elbow pipe’s lifespan was twenty-five years; however, the pipes in question ...
Hybrid fuzzy sliding mode for stick-slip suppression in drill string systems
(
Korean Society of Mechanical Engineers
, 2022 , Article)
Stick-slip vibration is one of the main factors that contribute greatly to reducing the service life of drill string equipment and decreasing the efficiency of the overall drilling system. Thus, it would be very desirable ...
Review of innovative approaches of thermo-mechanical refrigeration systems using low grade heat
(
Hindawi
, 2020 , Article)
Cooling and refrigeration systems consume around 17% of the world-wide electricity. Enhancing the performance of these systems, using renewable energy resources and waste heat recovered from industrial processes, will lead ...
Synergetic effects of dodecylamine-functionalized graphene oxide nanoparticles on antifouling and antibacterial properties of polysulfone ultrafiltration membranes
(
Elsevier
, 2021 , Article)
The potential use of dodecylamine-functionalized graphene oxide (rGO-DDA) nanoparticles as an antifoulant and antibacterial nanofiller was investigated. GO and rGO-DDA were analyzed using Raman spectroscopy, FTIR, SEM, ...
Mechanical and Fatigue Behavior of Cellular Structure Ti-6Al-4V Alloy Femoral Stems: A Finite Element Analysis
(
MDPI
, 2022 , Article)
Repetitive loads acting on the hip joint fluctuate according to the type of activities produced by the human body. Repetitive loading is one of the factors that leads to fatigue failure of the implanted stems. The objective ...
Mechanical and durability properties of ultra-high performance steel FRC made with discarded materials
(
Elsevier
, 2021 , Article)
This study investigates the mechanical and durability properties of 12 ultra-high performance fiber reinforced concrete (UHPFRC) mixes manufactured using alternate aggregate sources. Natural gabbro aggregates (GA), steel ...
Unaligned inductance calculation using flux tube approach for rotor conducting screen-based SRM
(
John Wiley and Sons Inc
, 2021 , Article)
This article investigates the effect of utilising rotor conducting screens within a switched reluctance machine (SRM). Conducting, non-magnetic materials such as aluminium or copper are inserted into the interpole regions ...
NABNet: A Nested Attention-guided BiConvLSTM network for a robust prediction of Blood Pressure components from reconstructed Arterial Blood Pressure waveforms using PPG and ECG signals
(
Elsevier
, 2022 , Article)
Backgroundand Motivations: Continuous Blood Pressure (BP) monitoring is crucial for real-time health tracking, especially for people with hypertension and cardiovascular diseases (CVDs). The current cuff-based BP monitoring ...
