Performance optimization of hybrid fiber concrete according to mechanical properties
(Elsevier, 2020)
In this research, interactional effects of four different fiber types, (steel, glass, synthetic and polypropylene) fly ash replacement ratio with cement, electrical arc furnace slag replacement ratio with natural aggregate ...
Recent developments in joining of aluminum alloys
(Springer, 2017)
The mass saving potential of light-weight materials, such as Al alloys, is beneficial for fuel economy and reducing CO2 emissions. However, the wide-spread use of these alloys has been long hindered due to the difficulty ...
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 ...
Second-order sliding mode control design and experimental application to a servo motor
(Institute of Electrical and Electronics Engineers Inc., 2017)
In this study, first-order and second-order sliding mode speed controller for the Precision Modular Servo (PMS) setup produced by Feedback Instruments is proposed. The second-order sliding mode controller which permits ...
Tunable perfect metamaterial absorber and sensor applications
(Springer, 2016)
Operation frequencies of traditional metamaterial absorbers are fixed meaning that it is not possible to change that frequency after the fabrication. Therefore, more studies are focused on the design of Tunable metamaterial ...
Improving the aging resistance of bitumen by addition of polymer based diethylene glycol
(Elsevier, 2018)
This study deals with improving the short-term aging resistance of bitumen with a new material, a diethylene glycol based polyboron compound (DEGPB). The compound was synthesized chemically and used 50/70 penetration grade ...
Sensitive Metamaterial Sensor for Distinction of Authentic and Inauthentic Fuel Samples
(Springer, 2017)
A metamaterial-based sensor has been realized to distinguish authentic and inauthentic fuel samples in the microwave frequency regime. Unlike the many studies in literature on metamaterial-based sensor applications, this ...
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 ...
