Eğilme tesirleriyle birlikte kesme tesirlerinin de dikkate alındığı teori, literatürde Timoshenko kiriş teorisi olarak bilinmektedir. Bu teoriye uygun davranan kirişlerin serbest titreşim analizi mühendisliğin ilgi çeken konuların birisi olmuştur. Timoshenko k…
A serial hybrid optical amplifier composing of two amplification stages of erbium-doped fiber (EDF) amplifier covered C-band window and Raman fiber amplifier (RFA) covered L band window demonstrated. In this paper, the optimizations were done to obtain the opt…
In this paper, the steps in the production process of forming hybrid composite coatings on surface of the ZA-27 alloy known as a sliding bearing material, and analysis of surface morphology of the coated samples were investigated. The process includes forming …
In 2012 Karapınar and Samet introduced the notion of α- contractive mappings and proved some well-known fixed point theorems. On the other hand in 2006 Mustafa and Sims gave the definition of G-metric space which is the generalization of metric space. In 2013 …
Bu çalışmada, frekans çözünürlüğünün (yankı çözünürlüğünün) R-MUSIC (Root-MUSIC, Çoklu Sinyal Sınıflandırma) ve ESPRIT (Rotasyonel Değişmezlik Tekniği ile İşaret Parametrelerinin Kestirimi) yöntemleri kullanılarak nasıl değiştiği incelenmiştir. Bu yöntemler,…
Tek Fazlı Şebeke Kalkışlı Sabit Mıknatıslı Senkron motorlar (TF-ŞKSM) günümüz endüstrisinde kullanılan standart indüksiyon motorlarına göre özellikle küçük boyutlarda daha yüksek verimlilik sunabilmektedirler. Verimliliğin artması çevre üzerindeki olumsuz et…
Density functional theory (DFT) is a computational quantum mechanical modelling method used in physics, chemistry and materials science to investigate the electronic structure (principally the ground state) of many-body systems, in particular atoms, molecule…
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…
