Snow observations are important in many mountain areas to quantify the water stored snowpacks and predicting runoff during melting period. In this study we compare performance of five different regional-scale gridded snow products reproduce equivalent (SWE) Upper Euphrates region (Karasu Basin, 10,275 km2), with from automatic weather stations catchment through Taylor diagrams. The compared ERA...

This research work highlights the effects of acoustic emission (AE) signals emitted during the milling of H13 tool steel as an important parameter in the identification of tool wear. These generated AE signals provide information on the chip formation, wear, fracture and general deformation. Furthermore, it is aimed at implementing an online monitoring system for machine tools, using a sensor f...

Laser Aided Manufacturing Process (LAMP) can be applied to repair steel die/molds which are currently repaired using traditional welding process in industry. In order to fully understand the advantages of laser deposition repair process over traditional welded-repair process, the mechanical properties such as tensile strength and hardness of H13 tool steel samples produced by these two processe...

Self-organization during friction in complex surface engineered tribosystems is investigated. The probability of self-organization in these complex tribosystems is studied on the basis of the theoretical concepts of irreversible thermodynamics. It is shown that a higher number of interrelated processes within the system result in an increased probability of self-organization. The results of thi...

Grid integration of Renewable Energy Systems (RES) involves various types power electronics-based converters and inverters. The use these electronic-based devices results in inducing both current voltage harmonics to the grid. In order reduce harmonics, especially for large-scale RES, harmonic forecasting is one many techniques used design mitigation devices. core objective this work develop a ...

A comprehensive study of pulsed nitriding in AISI H13 tool steel at low temperature (400°C) is reported for several durations. X-ray diffraction results reveal that a nitrogen enriched compound (-Fe2-3N, iron nitride) builds up on the surface within the first process hour despite the low process temperature. Beneath the surface, X-ray Wavelength Dispersive Spectroscopy (WDS) in a Scanning Elec...
