Aluminum based metal matrix composites are frequently used in automotive, aircraft, space, automotive, agricultural and building industries due to their easy shaping, good heat and electrical conductivity, low density, high strength and toughness. In these com…
In this study, 0-12wt.% of Si3N4 or 0-30wt.% of SiC was added to the aluminum matrix by powder metallurgy method. Hence, the effect of reinforcement elements’s (SiC or Si3N4) amount on the mechanical properties was examined. Micro structures and crystal struct…
Climate change effects have been remarkably today; the determination of trends in temperatures, precipitation, stream flow, winds and evaporation has become considerable for the planning and management of water resources and engineering projects. Nowadays ther…
Stress corrosion is a dangerous type of corrosion occuring as a result of effective with corrosive environment and stress of sensitive a material. Many metallic material may be exposed to stress corrosion damage depending on operating conditions. In order to d…
Aim of the study: It is important to be able to plan the production transmission and distribution necessary for uninterrupted electricity and to use the electricity more efficiently and to make demand forecasts. For this reason, it is aimed to estimate the ele…
TRIZ, geçmiş problemlerin çözümlerini özetleyen ve gelecekteki problemlerin sistematik bir yöntem ile çözülmesine yardımcı olan, inovatif problem çözme tekniğidir. Günümüzde şirketlerin rekabet ortamında daha verimli, üretken olabilmeleri ve piyasada varlıklar…
It is important to determine the initial level of failures of induction motors used in many industrial applications. The sudden stops of the system can be prevented with the pre-detection of the fault. The experiment mechanism was established to detect mechani…
In this study, mathematical modeling of outer rotor brushless direct current motor (BLCD) is performed. Brushless direct current motor is highly preferred in industrial applications when compared the other motor types with considering advantages and disadvanta…

Tüm dünyada özellikle de kent merkezlerinde yaşayan insan nüfusu her geçen gün artmaktadır. Nüfus artışına bağlı olarak sosyal, ekonomik ve çevre sorunlarını da her geçen gün artmaktadır. Günümüzde kent merkezlerinde görülen en önemli çevre sorunlarından biri …
The Motion Picture Association of America(MPAA) is used in the United States to rate a film's compatibility via its content. These systems evaluate ratings according to the scenes in the movies. In this work, a deep learning based classification technique is p…
Digital image processing has become popular research area recently because of its widespread application compatibility such as security, robotics, quality control, face authentication. Skin segmentation methodology, which is a tool of digital image processing,…
Elektrik sistemlerinin arızasız ve güvenli bir şekilde çalışabilmesi, akım ve gerilim gibi devre büyüklüklerin 50 Hz frekansta ve sinüsoidal formda olmasına bağlıdır. Bununla birlikte bir çok nedenlerden dolayı bu temel büyüklükler sinüsoidal özelliklerini k…
Milli Eğitim Bakanlığı tarafından en son 2017 yılında belirlenen öğretmen genel yeterlikleri, öğretmenlerin üniversite öğrenimleri süresince aldıkları eğitimle birebir ilişkili olmalıdır. Ayrıca branş bazlı olarak bakıldığında her branşın kendine ait yeterli…
In this study, combined thermal radiation and natural convection heat transfer problem are investigated in glass and plastic covered flat solar collector. The bottom plate that absorbs the sunlight and the ambient temperature are kept constant. Solar collector…
In addition to developing information technologies, medical decision support systems are used to make decisions more effective, faster, more accurate and easier to make decisions in medicine and healthcare. With data mining, which is an important part of med…
In this paper, a structural-output is obtained to estimate 3D human pose using 3D human point cloud and monocular images. The Neural Network takes a human image and 3D pose as inputs and gives outputs a score value. Conditional Random Field (CRF) approach is u…
It was aimed to find the structural discontinuities of the Eastern Anatolia Region by using horizontal gradient magnitude technique. When determining the structural discontinuities of the region, the maximum amplitudes of the horizontal gradient magnitude we…
