Stability investigation of a deep shaft using different methods
(ASCE- American Society of Civil Engineers, 2021)
The New Zigana Tunnel is, at 14.5 km long, the longest highway tunnel project in Turkey. In this project, it is planned to construct two service shafts to provide access to outside the tunnel and temporary ventilation. ...
Parallel-connected buck-boost converter with FLC for hybrid energy system
(Taylor & Francis Ltd., 2021)
The control of renewable energy sources is more complicated when used as hybrid energy systems. Power electronic circuits are used to convert and store the electrical energy generated from renewable energy sources. However, ...
Sedimentological and geochemical characteristics of Lower Jurassic Sandstones from Gumushane, NE Turkey: implications for source to sink processes, paleoenvironmental conditions, provenance and tectonic settings
(Taylor & Francis Ltd., 2021)
The eastern Sakarya Zone (SZ), one of the Alpine Himalayan Belt's main components, has complex Mesozoic-Cenozoic geodynamic evolution, which remains controversial. Early-Middle Jurassic volcano-sedimentary successions ...
Measuring instructional design competencies of future professionals: construct validity of the ibstpi(R) standards
(Springer, 2021)
Competencies that constitute the instructional design profession and how these competencies should be measured have been of interest to researchers for many years. Among the competency sets developed to date, the ibstpi(R) ...
Optimization of strength, ductility and wear resistance of low-carbon grade A shipbuilding steel by post-ECAP annealing
(EDP Sciences, 2021)
Effect of equal channel angular pressing (ECAP) and subsequent annealing on the microstructure, mechanical properties and tribological behavior of grade A shipbuilding steel was investigated. Coarse-grained microstructure ...
Effect of mineralogical composition of clinoptilolite-bearing tuffs on their performance as a natural pozzolan in cementitious systems
(Techno-Press, 2021)
In this study, pozzolanic reactivity and strength activity of zeolitic tuffs containing similar amount of zeolitic phase (clinoptilolite) and different types and amounts of impurities were examined in order to understand ...
Effect of double cross sectional ratio on performance characteristics of pulsating heat pipes
(Elsevier, 2021)
Effect of double cross sectional ratio on performance characteristics of pulsating heat pipes is experimentally investigated. The cross sectional ratios in the evaporator and condenser sides are different from each other, ...
Investigation of flat plate type pulsating heat pipes via flow visualization-assisted experiments: Effect of cross sectional ratio
(Elsevier, 2021)
In the present study, combined influence of filling ratio, geometry, inclination angle and heating power on heat transfer characteristics of the pulsating heat pipes (PHPs) are investigated accompanying analysis of complex ...
Investigation of continuous and discontinuous contact cases in the contact mechanics of graded materials using analytical method and FEM
(Techno-Press, 2021)
The aim of this paper was to examine the continuous and discontinuous contact problems between the functionally graded (FG) layer pressed with a uniformly distributed load and homogeneous half plane using an analytical ...
Thin film coated windows towards low/zero carbon buildings: Adaptive control of solar, thermal, and optical parameters
(Elsevier, 2021)
Thin film coated windows are considered as the future of fenestration market owing to their characteristic features such as solar radiation and visible light control, UV and IR rejection and promising U-value range. Within ...
