Comparative implementation of thermoelectric coolers in transformer cooling
(Taylor & Francis Ltd., 2023)
In this study, using a comprehensive experimental methodology, thermoelectric coolers (TECs) are used for transformer cooling in contrast to classical methods such as air, oil, and water. The effects of this operation are ...
Recently-discovered Bahçecik Au±Ag mineralization in the Eastern Pontides, Gümüşhane-NE Türkiye: geological and geochemical implications on the intermediate sulfidation epithermal deposit
(Taylor & Francis Ltd., 2023)
Intermediate sulfidation epithermal deposits represent significant reservoirs of precious metals, playing a crucial role in global mining operations. The Anatolian Peninsula, predominantly characterized by relatively young ...
Geochemistry of the Lake Sediments on Robert Island, South Shetland Islands, Antarctica: implications for weathering processes in Polar areas
(TUBİTAK Scientific & Technical Research Council Turkey, 2023)
The preliminary results of geochemical analyses of the surface sediments from 4 lakes on Robert Island, South Shetland, Antarctica, are presented herein. The samples were collected during the Turkish Antarctic Expedition ...
Machine learning driven optimization and parameter selection of multi-surface HTS Maglev
(Elsevier, 2024)
This research aims to tackle the challenges posed by precise force measurement for high temperature superconducting (HTS) Maglev systems, including mechanical constraints, step motor limitations, and sensor resolutions. ...
New modified carrier-based level-shifted PWM control for NPC rectifiers considered for implementation in EV fast chargers
(TUBİTAK Scientific & Technical Research Council Turkey, 2023)
In this study, the aim is to evaluate three-phase (3ϕ) AC/DC neutral point-clamped (NPC) power factor-corrected (PFC) multilevel converter performance for electric vehicle (EV) fast chargers. Power factor correction for ...
A New index and control method of filling effect for cemented paste backfill in coal mines
(Taylor & Francis Ltd., 2023)
The scientific filling effect characterization is very important for backfill mining. A new filling effect index, the final backfill ratio (FBR), is proposed through experimental tests and theoretical analysis, and the ...
Polymer shape effect on damage evolution, internal defects and crack propagation of 3D-printed polymer-based cementitious backfill
(Elsevier, 2023)
The strength property and damage mode of cementitious tailings backfill (CTB) are governed by its structural characteristics in the presence of the microstructure/internal defect effects. However, this correlation is still ...
Enhancing filtration performance of submicron particle filter media through bimodal structural design
(Wiley, 2023)
Depth filtration is a widely utilized mechanism for submicron aerosol filtration using disposable filter cartridges and facemasks. The filter media should be carefully engineered to reach high filtration efficiency and ...
Non-Newtonian laminar pulsating heat and fluid flow in plane duct
(Wiley, 2023)
In the present study, laminar pulsating power-law momentum and heat transfer in a uniformly heated plane duct is studied analytically. Assuming that fully developed conditions exist both hydrodynamically and thermally, a ...
Exergy analysis of a high pressure multistage hydrogen gas storage system
(Elsevier, 2011)
This study presents a parametric study on the performance aspects, through exergy analysis, of the multistage hydrogen gas storage subsystem in a hydropower-based-hydrogen gas fueling station producing 3 kg of hydrogen per ...
