Textile industry has an important role in the economic development of Turkey. According to the Ministry of Economy, textile exports, which were about $ 6.36 billion in 2007, were about $ 10.11 billion at the end of 2017. The share of the textile sector in the …
Asynchronous motors are the most preferred engines in the industry due to factors such as their stable speed, economic and operational safety. Recently, asynchronous motors have been used as generators in the power generation sector and especially in wind turb…
Environmental problems, also defined as destruction of ecologic balance, are among the most significant problems of today’s world. Increasing mankind pressure on environment have made destructions of ecological balance evident. Such a case then emerged a nee…
In today’s world with ever-aggravating environmental problems, environmental training has a great significance in mitigating and coping with such problems. Environmental pollution is the greatest problem today and certain measures and steps should urgently be …
Ceramic materials are characterized by outstanding hardness, extreme compressive strength and elastic modulus, wear resistance, thermal shock resistance, chemical stability and high temperature properties. Therefore they have potential materials to be use at i…
Superhydrophobic surfaces and materials received great attention of scientists and engineers due to their unwetting, self cleaning and antimicrobial properties. Hydrophobic surfaces are defined as having sessile water drop contact angle greater than 90°, while…
In our country, industrial investments and manufacturing capacity increase day by day. It is possible to enhance standard and quality of product, increase manufacturing capacity, constitute production line with less energy consumption by adapting developing te…
Jeotermal enerji varlığını dünyanın kuruluşundan bu yana sürdürmüş temiz bir enerji türüdür. Her geçen yıl yeni jeotermal alanlar bulunmakta ve kullanım alanları hızla artmaktadır. Enerji maliyetlerinin yükselme eğiliminde olduğu günümüzde jeotermal enerji alt…
Because today’s architecture is characterized by various concepts and numerous designs instead of an architectural style, it is heavily described by the identity of the architect. However, according to the d-gene pool theory of Karina Moraes Zarzar, this ident…
Yenilikçi soğutma teknolojileri arasında yer alan ısı boruları, sahip olduğu özgün karakteristikler sebebiyle son yıllarda önemli bir araştırma alanı olarak ortaya çıkmaktadır. Isı boruları, taşınımla ısı geçişi ve sıvı-buhar faz değişimi ilkelerinden faydalan…
The effects of climate change in the world are observed to have significant effects on different environmental variables. Therefore, changes in climate parameters should be examined and analyzed. These changes can be determined by parametric and non-parametr…
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…
