In many engineering applications such as aerospace, automotive and telecommunications, icing leads to mechanical and socio-economic problems such as efficiency reduction, decreased power transmission, security threat, material damage and energy waste. Theref…
Rubble of destroyed buildings in Turkey is a growing environmental problem, in Ankara only, there are 12 landfills to collect and store them. Adobe is a world common building material; many studies inferred its environmental qualities. This study examines th…
Boundary-value problems with eigenparameter dependent boundary conditions is one of the most extensively developing fields in pure and applied mathematics. First, we cite the works of Walter and Fulton, both of which have extensively bibliographies, a discus…
Recently, the basis properties and eigenfunction expansions in various function spaces of the eigenfunction of the regular boundary value problems with spectral parameter in the boundary conditions have been investigated by many mathematicans. However in diff…
Çarpan jetler, iyi bir ısı transferi performansı sağlamaları nedeniyle genellikle sanayide elektronik ekipmanların ısıl problemlerini çözmek için kullanılırlar. Bu çalışmada, tek bir hava jeti akışı kullanılarak bir tarafı açık, üç tarafı kapalıdikdörtgensel…
According to the political economy theory and neoclassicists, institutional discrimination is one of the obstacles that we face in politics in modern countries. It is generally systematic and malicious. In doing so, patronage relationships come into play. Ec…
Organic dyes and complexes such as phthalocyanines (Pcs) may show photocatalytic properties against to photocatalytic degradation of pollutants [1]. The use of metallo phthalocyanines as organic photocatalysts in solution derives from their intense absorption …
In this study, abrasive wear behaviors of Co-Cr-Mo alloy (ASTM F75) which is produced by casting method, were investigated. The prepared test samples were subjected to abrasive wear tests with different emery papers on the pin on disc wear device. In the abras…
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 …
Ergonomics is the process of designing or arranging workplaces, products and systems so that they fit the people who use them. Ergonomics is a branch of science that aims to learn about human abilities and limitations, and then apply this learning to improve p…
It is aimed to analyze the layout of eight baths, which have survived from the Menteşeoğulları Principality period to the present day, by means of rule based analysis. In addition, in this study, it is examined how space fiction, Inter-space relationship and…
In this study, the main contributions of establishment of Kartepe Test and Research Centre (KARTEAM) project funded by East Marmara Development Agency (MARKA) within the scope of financial support program in 2016 is explained for applied technical education an…
The marketing strategy is concerned with the creation of the target market selection and necessary marketing mix in order for the businesses to achieve their marketing objectives. Marketing creativity includes creative applications in solving marketing problem…
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…
DC-DC boost converters are usually used so as to increase voltage in battery charging of electrical vehicles, power factor correction circuits and solar photo voltaic panels etc. applications. The control of these converter types is realized with Pulse Width M…
The waste problem has become a non-ignorable issue in apparel industry like other manufacturing industries and the concept of sustainability has come to the forefront. The term ‘sustainability’ refers to the long-term viability of business operations and their…
In this study, Al-12Si ingot alloy was melted in an electric resistance furnace and then poured into metal moulds through traditional casting method. Optimum machining conditions is aimed to determine by investigating the effects of cutting parameters on surfa…
Günümüzde birçok alanda kullanılan Kablosuz Algılayıcı Ağlar genellikle açık alan uygulamalarında kullanıldıkları için dışarıdan gelen farklı saldırılara karşı korumasız durumda olabilirler. Ağı saldırılara karşı korumak ve verilerin güvenliğini sağlamak, Kabl…
