A new PWM technique for three-phase three-level neutral point clamped rectifier
(Springer, 2023)
In this study, the aim is to evaluate three-phase (3 phi) three-level (3L) neutral point clamped AC/DC rectifier for high-power applications. The rectifier analysis has been simulated using a new modified carrier-based ...
Quantitative analysis of pore characteristics of nanocellulose reinforced cementitious tailings fills using 3D reconstruction of CT images
(Elsevier, 2023)
This study aims at analyzing the influence of contents and types of various nanocelluloses (e.g., CNF, CNC, and MFC) and intermediate microstructure on strength/fracture features of cementitious tailings backfill (CTB). ...
Development and characterization of a new solid polymer electrolyte for supercapacitor device
(Hindawi, 2023)
In this study, solid polymer electrolytes (SPEs) are based on methylcellulose (MC) used as a polymer host and sodium iodide (NaI) as a dopant. The SPE films are developed using different contents of ethyl carbonate (EC) ...
Comparative investigation of different types of expanding micro-pin-fin heat sinks at low mass flux
(Elsevier, 2023)
Expansion of cross-sectional area of flow passages in micro-pin-fin heat sinks provides advantages due to suppression of bubble-confinement problem. However, low mass flux in addition to orientation of fins and existence ...
Coupled longshore and cross-shore models for beach nourishment evolution at laboratory scale
(ASCE Library, 2008)
A series of three-dimensional laboratory experiments on beach nourishment behavior are described and analyzed. The experiments were designed to isolate the influences of berm height, beachfill median grain size, wave height, ...
Identifcation of goaf instability under blasting disturbance using microseismic monitoring technology
(Springer, 2023)
Micro-seismic (MS) technique can be used to appreciate rock failure process and severity of damage by quantifying micro-earthquakes in terms of time, location, grade, and energy release. Based on 3D laser detection and ...
Analyzing the microstructure of cemented fills adding polypropylene-glass fibers with X-ray micro-computed tomography
(Elsevier, 2023)
Fiber reinforced cementitious tailings backfill (FRCTB) is progressively employed in mining industry due to its high strength/stiffness-to-weight ratio. However, the wide use of the FRCTB technique requires further study ...
Investigation of beaches suitable for nourishment in Rize Province, Turkey
(Middle East Technical University, 2009)
Black Sea Coast Motorway was recently built along the shore (about 600 km), and a number of beaches were destroyed. Now there are a couple of short beaches in Eastern Black Sea region. People need new beaches. On the other ...
Mechanical properties of Al-9Si-0.6Mg-0.1Sr alloy processed by successive hot and cold multi-directional forging
(Springer, 2023)
In this study, the effect of successive hot and cold multi-directional forging (MDF) on the mechanical properties of the Al-9Si-0.6Mg-0.1Sr alloy was explored. The alloy was first homogenized and then forged at 200°C from ...
Monitoring sediment transport in certain harbor launches in the southeastern black sea
(Multidisciplinary Digital Publishing Institute (MDPI), 2023)
Abstract: The problem of shoaling on coastal structures is the result of an event that occurs as part
of the natural cycle. In cases where shoaling cannot be detected or prevented, various economic
and operational problems ...
