Developing technology in the manufacturing industry and the requirement of high precision parts reveals micro machining. It is possible to produce workpieces both at high speed and with high precision by means of micro-mechanical machining.The finite element m…
The collective system, which includes the automation system, data exchanges and production technologies is referred to as Industry 4.0. This system has two main components. The first is the new generation of software and hardware, and the second is the cyber p…
In this study, mixed convection heat transfer and fluid flow in a three-dimensional horizontal duct with three different geometries of cavity were investigated numerically. Air flows in a square duct which is heated by a cavity with triangular, a rectangular a…
Contact pressure is very critical for wear test. In order to make true wear experiment, counter body, surface, wear load, surface roughness, and the hardness of materials should be selected correctly. Maximum contact pressure forms at hertz point. In this stud…
Carbides change highly effective on the mechanical and tribological properties of the coatings. For this reason, it is very important to determine the carbide ratio in the microstructure correctly. Researchers mostly try to determine phase ratios by optical im…
The mobile processors with the increasing computational capabilities and software supports for the devices equipped by them have attracted the researchers’ attention to check whether they can be used for solving complex problems or not. In this study, a mobile…
Until the last four decades, number of teachers have been insufficient in public schools of Turkey. Nowadays, there is still an overall imbalance between supply and demand for teachers, because teacher supply is in surplus. It is associated with engaging short…
3 + 1 Training Model have been developed in vocational high schools in Turkey in order to train the qualified personnel needed by the industry with the technology and knowledge of the day at the right time. In this training model, the students receive 3 semest…
An analysis of mechanical stresses under an external AC magnetic field in a coil stack was performed using the finite element method solving "mechanical equilibrium equation" by Comsol Multihysics finite element software. A-V formulation has been used for the …
In this work, the influence of the amplitude for four frequencies and directions of the applied field on the AC loss of an HTS pancake coil is extensively investigated by the finite element method in COMSOL Multiphysics software with an AC/DC module. The numbe…
Plastic injection molding is a manufacturing process of heating plastic granules and forcing melted plastic into a mold cavity and removing from the mold after cooling. One of the most important elements in the production of parts by plastic injection molding …
Today, it is possible to access a lot of information by using medical imaging data (CT and MR). In recent years, CT and MR data have been processed and transferred to computer aided design (CAD) programs. In fact, these solid models modified in the CAD environ…
In this study, thermodynamic analysis of a geothermal power-based district energy conversion system which produces electricity, hot water, heating and cooling are investigated. The energy produced from geothermal resource can be utilized to drive a double stag…
In this paper, signal recognition system is proposed for classification of soil types and buried object by using feature extraction and artificial neural networks. Using GprMax simulation program, 300 GPR A scan signals were obtained for different ground plane…
İnternette yaygın veri kullanımı ve kapasitesi her geçen gün hızla artmaktadır. Bu nedenle, bu verilerin aktarımı veya iletimi sırasında veri güvenliği önem arz etmektedir. Dolayısıyla, birçok veri şifreleme algoritmaları kullanılmaktadır. Literatürde en yaygı…
Several test suites have been developed to test the statistical properties of random numbers generated from pseudotrue random number generators. Some of these are Crypt-X, Diehard, FIPS 140, NIST 800-22 AIS31 test suites. In this study, web based application o…
In the present study, energy and exergy analyses of a solar powered absorption refrigeration system are corried out by terms of the first and second laws of thermodynamics. NH3-H2O fluid couple is used in the system. The analyses are performed with the help of…
Exhaust gas distribution in street canyons is one of the important research subjects in urban air quality studies. Vehicle emissions are an important group of pollutants in urban areas. In this study, the dispersion of exhaust emissions from vehicles in canyon…
This paper describes a laboratory application for the forecasting the dielectric properties, using an artificial neural network embedded in a microprocessor. The dielectric permittivity and loss factor of the insulation material were determined as a function o…
