Östenitik paslanmaz çelik malzemeler düşük ısıl iletkenlik ve yüksek korozyon direnci gibi özelliklerinden dolayı yaygın olarak kullanılmaktadır. Bu çalışmada AISI 304 ve AISI 316 L östenitik paslanmaz çelikler karbür kaplamalı kesici takımlar ile parmak freze…
Teknolojinin gelişimiyle birlikte her geçen gün daha kaliteli hale gelen ve boyutları büyümekte olan sayısal görüntüleri saklamak ve transfer etmek ciddi problem haline gelmektedir. Boyut ve kalite arttıkça görüntüyü saklamak için gereken bellek alanı artmakta…
Additive manufacturing which is developed in the last half century is promising manufacturing technology. It uses layer-wise production method for obtaining finished product. In recent years, thousand researches were made but there was still gaps about impac…
TiO2 films have been deposited by sol gel spin coating technique onto glass and p-Si substrates. TiO2 films were prepared using two different sols. The physical properties of the TiO2 films were examined based on two different parameters. In the first study,…
In this study, hybrid composite structures were manufactured by vacuum assisted resin transfer molding method using three different woven fabrics (jute, E-glass and carbon) as the reinforcing material and polyester resin as the matrix material. All composite…
ZnO nanopowders were synthesized via microwave assisted hydrothermal method at different precursor solution molarities. For this, the aqueous solutions of zinc aceatate dihydrate and sodium hydroxide were prepared at different molarity as precursor materials…
In this work, the effects of bis (2-methoxy-4-allylphenyl) oxalate (I) on levitation (Fz) and lateral forces (Fx) of bulk MgB2 superconductor has been investigated and reported for the first time. All samples were prepared from magnesium powder (Mg, 99.8 %),…
Palladium-catalyzed Suzuki Miyaura cross coupling reactions (SM Coupling) are made using organoboronic acid and halides. 9-(4-anthracene-9-yl-phenyl)-9H-carbazole (III) was synthesized by using Ullman and Suzuki coupling reactions. Structural analysis of the…
Erosion is among the leading factors threatening our sources of soil and water. The use of soil susceptibility indices to determine erosion and risk situations has an important place especially in erosion studies. The susceptibility of soil to erosion is the…
It is well-known that the Sturm-Liouville type boundary value problems appears in solving many important problems in physics. For example, some problems of theory of elasticity in a half-strip ,the problems of theory of vibrations of an elastic cylinder redu…
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…
In the history of economic thought, different hypotheses have been formed which reveal the interaction between public expenditure and national income. These hypotheses can be decomposed according to their economic and political content. Political content hypot…
Many communication protocols are being used and standardized for the Internet of Things (IOT) infrastructure. At the forefront of the features expected from the protocols used is the efficient operation of a limited bandwidth and low bandwidth electronic devic…
In order to evaluate different modeling techniques for Unglazed Transpired Collectors (UTC), not only mathematical modeling method for UTC based on heat transfer expressions to estimate the various heat transfer coefficients for the UTC components and empirica…
The particulate matters in ambient air were sampled in Denizli, Turkey in winter and spring using Bergerhoff Method. The average dry deposition fluxes were calculated as 152.1 ± 30.7 mg m-2 day-1 and 333.9 ± 214.2 mg m-2 day-1 in spring and winter, respectivel…
Structural health monitoring is an interdisciplinary field that enables early detection of undesirable situations such as damage or defects that occur in the structure or its components thanks to its ability to self-diagnosis. It is possible to use safer engin…
To investigate how foreign trade deficits and budget deficits of Turkey navigated pre and post customs union (CU) with European Union. In the study, for the budget deficits (BD), General Directorate of Budget and Fiscal Control (BUMKO) and also for the foreign…
The quality control process for determining fabric faults causes high cost and time loss when performed with human eyes. Adding a real-time system to the fabric production mechanisms is very difficult to detect mistakes. In this study, 5 MP Raspberry Pi camera…
Maxwell denkleminin AV formülasyonu esas alınarak, zamana bağlı bir akım altında süperiletken telin elektromanyetik özelliklerini çözmek için yeni bir sayısal model geliştirilmiştir. Farklı akım genlikleri için alternatif akım (AA) kayıpları hesaplanmış ve iki…
