Experimental Verification of Cell Shape-Collapse Relationships in Metallic Foams by Photoelasticity Method
(Gazi University, 2019)
In the present study, the effect of cell morphology on mechanical properties in metallic foams with Al based closed cells was examined. AlSi8Mg0.8 alloyed metallic foam materials were produced by the Powder Metallurgy (PM) ...
A Study on Fuel Cell Electric Unmanned Aerial Vehicle
(Ieee, 2019)
This study focused on fuel cell electric unmanned aerial vehicle (FC-EUAV) in order to find solutions to problems such as the short-lived and limited long flight endurance of unmanned aerial vehicles operating with fossil ...
Performance Results of Photovoltaic/Fuel Cell Based Hybrid Energy System under Variable Conditions
(Ieee, 2019)
In this paper, dynamic operation and optimization of a grid connected hybrid system including photovoltaics (PV) and fuel cell (FC) is presented. For this purpose, abc/dq transform based power flow controller is used in ...
Utilization of boron waste borogypsum in mortar
(Elsevier, 2019)
In this study, mortars containing borogypsum (MCB) were investigated to understand the effect of borogypsum on mortars and if borogypsum could be used as a mineral admixture in the mortars. Borogypsum were replaced with ...
Artificial neural network approach for locomotive maintenance by monitoring dielectric properties of engine lubricant
(Elsevier, 2019)
In this paper, we proposed an approach for locomotive maintenance systems by observing engine lube oil. The mechanical particles in lube oil give information about locomotive engine system condition. The engine lubricant ...
Proximal probe-like nano structuring in metal-assisted etching of silicon
(American Institute of Physics Inc., 2019)
We use silicon having multiple crystalline orientation domains and high metal doping in metal assisted chemical etching (MACEtch) in HF/H2O2. In device-quality silicon, MACEtch produces high-aspect ratio anisotropic (1-D) ...
A Nondestructive Method for Determining Fiber Content and Fiber Ratio in Concretes Using a Metamaterial Sensor Based on a V-Shaped Resonator
(Springer, 2019)
A micro sensor based on a V-shaped resonator (VSR) is implemented for the purpose of determining fiber content and ratio in construction materials as a nondestructive method. Concrete is investigated as the construction ...
Wide band fractal-based perfect energy absorber and power harvester
(Wiley, 2019)
In this article, a novel wide band polarization and incident angle independent metamaterial absorber (MA) and energy harvesting applications which operates at C (4GHz-8 GHz) and X (8GHz-12 GHz) is proposed. The unit-cell ...
Determination of optimum post embedment depth for C120 steel posts using field and full scale crash test
(Taylor & Francis Ltd, 2019)
C120 steel sections are the most widely used post shapes in European guardrail designs. The design length of these posts is determined based on guardrail containment level and engineering judgment. The soil properties where ...
Crankcase explosion for two-stroke marine diesel engine by using fault tree analysis method in fuzzy environment
(Elsevier, 2019)
The purpose of this study is to investigate crankcase explosion in two-stroke marine diesel engine systematically by using fault tree analysis method in fuzzy environment for system reliability and shipping sustainability. ...
