This study aims to investigate the effect of pitching motion of a NACA 0012 airfoil on the lift and drag coefficients at different reduced frequencies for a flow over the airfoil at Reynolds number of 5x105. A two-dimensional computational analysis was perform…

Turizm, dünya genelinde en hızlı gelişen ve büyüyen endüstrilerden biri olarak dikkat çekmektedir. Teknolojide yaşanan gelişmeler insanların seyahatlerini kolaylaştırmakta, turizme daha fazla kişinin katılımını sağlamaktadır. Bununla birlikte, engelli bireyler…

Fotovoltaik (FV) sistemler birkaç W’dan, MW’a kadar ölçeklendirilebilmesi gibi özelliklerinden dolayı en çok yaygınlaşan yenilenebilir enerji kaynağı türüdür. Bu enerji kaynağından en yüksek oranda yararlanılabilmesi maksimum güç noktasını izleyen (MPPT) dönüş…

The design of experiments is a highly effective offline quality improvement method to optimize the existing and new processes or products. In the literature, standard experimental situations have been paid a lot of attention. In a number of non-standard experi…

Dünyada enerji üretimi yapılan her yerde havayı kirleten maddeler atmosfere atılmaktadır. Özellikle yakma sistemlerinin baca ve egzozlarından çevreye yayılan bu kirleticiler insan sağlığını ve canlıların hayat şartlarını olumsuz yönde etkilemektedir. Yapılan b…

Accessibility is among the central issues in national and international policies aimed at catering for a more democratic social life, since its achievement promotes the right to full participation in all public services and community life, to a significant ext…

Very recently orthogonal cone metric spaces, orthogonal completeness and orthogonal continuity are described and fixed points of orthogonal contractions are investigated by Bilgili Gungor [4]. In this paper, some generalizations of fixed point theorems in [4] …

It is clear that the anthropologists launched by Edward B. Tylor in the classical religionswissenschaft period, having continued on the evolutionary line - for instance those of Robert R. Marett, George Frazer - with terms such as anxiety, devotion, fear, depr…

In this study, a PID controller with fractional order derivative filter (PIDFF) is designed for automatic voltage regulation (AVR) in power systems. In order to ensure maximum transient and steady state performance from the designed controller, the controller …

Anti-thyroid drugs are relatively simple molecules known as thionamides, which contain a sulfhydryl group and a thiourea moiety within a heterocyclic structure [1]. Methimazole (1-methyl-2-mercaptoimidazole) is widely used drug in medicine for treatment of hyp…

Companies in logistics sector aim to provide better services and to increase their profits by enlarging their carriage capacities. Therefore, companies expand their fleets by making new commercial vehicle investments. In this study, a general evaluation is con…

Hydrological drought is one of the most essential natural hazards attributing water scarcity and its global impact increases due to the climate change. In particular, the usage of climate models and rainfall-runoff models for projecting the severity of future …

Companies would like to gain a competitive advantage in today's world where global competition is intense by focusing on their main activities. Therefore, most of the companies use outsourcing for their logistics activities. Third-party logistics providers are…

The increase in firms in the furniture industry has made competition difficult. In this competitive environment, it is important to collect data and extract meaningful information. Every second, large amounts of data are generated on the Internet. The use of s…

Bu çalışmada UCI Makine Öğrenmesi havuzundan alınan kardiotokogram verisinde morfolojik örüntü sınıflandırması yapılmıştır. Sınıflandırıcı olarak kompleks değerli yapay sinir ağları kullanılmıştır. Sınıflandırıcının performansı 10-katlı çapraz doğrulama yaklaş…

Prediction in the medical field is a challenging problem and as a result many researchers have used different artificial intelligent methods including conventional Self Organizing Map (SOM) to achieve this task. SOM is a specialized clustering technique that h…

It is a fact that countries with robust and inclusive health services have a longer life expectancy at birth. Health services aim to improve and maintain health. In order to achieve these objectives, an integrated combination of various activities in which the…

Türkiye’de tüketim harcamaları içerisinde en fazla payı gıda ve alkolsüz içecek sektörü (%24.45) almaktadır. Bu kapsamda, böylesine önemli bir sektörde tüketici davranışları oldukça önem arz etmektedir.  Bu bağlamda çalışmada, içecek tüketim harcamalarında etk…

It is well known that non-Gaussian noise deteriorates the detection performances of the conventional detection methods. This problem is also encountered in cognitive radio where impulsive structure of noise negatively affects spectrum sensing. Multistage detec…

Haptic devices are used in a variety of virtual reality applications in order to allow user interaction with virtual objects. These devices transfer user comments such as rotations, transitions or deformations to the virtual environment and also transfer any r…
