Energy dissipaters used in open channels are devices designed to reduce the flow velocity and allow water to pass downstream without harming water structures and environment. In this study the effect of energy dissipaters on energy loss is investigated depende…

Bilişsel radyo kullanılmayan ya da az kullanılan spektrum bantlarına dinamik olarak erişim olanağı sağlayan ve kullanıcılar arasında herhangi bir olumsuzluğa neden olmadan spektrum paylaşımını gerçekleştiren yazılım tabanlı bir teknolojidir. Kablosuz haberleşm…

Evrimsel algoritma ve parçacık sürü algoritması çok uzun zamandır ayrı ayrı çeşitli karmaşık problemlerin çözümünde yaygın olarak kullanılan sezgisel algoritmalardır. Evrimsel algoritma canlıların çoğalmasını ve hayatta kalmak için en iyilerin seçilmesi tekniğ…

Gerçekleştirilen bu çalışmada, CNC dik işleme tezgâhında kesme parametrelerinin iş parçası yüzey pürüzlülüğü ve kesme kuvvetin üzerine etkileri incelenmiştir. Deneyler 1.5 mm sabit talaş derinliği, üç farklı kesme hızı (90, 120 ve 150 mm/min) ve üç farklı iler…

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 work, Intralube E with 0.38 % C press-ready mix powders were pressed with 550 MPa pressure and sintered 25 min at 1120 °C. Samples were coated electrochemically with nano diamond (ND) reinforced nickel to study the effect of nano composite coating on c…

Fins are basic structures which can be easily added to many engineering designs to improve heat transfer from hot surfaces. The addition of a fin to a particular heated surface can significantly increase the cooling at no extra cost. In some cases, standard fi…

This work is about a system that generates electrical energy with the heat energy from the evaporator of the air conditioner and cools the environment. It is applicable to all types of air conditioner and air conditioning systems. It generates electrical energ…

Spektrum algılamada amaç spektrum boşluklarının doğru ve hızlı bir şekilde algılanmasıdır. Bu nedenle bilişsel radyo ağlarının başarımı büyük ölçüde spektrum algılama işlevine bağlıdır. Bu çalışmada, bilişsel radyo ağlarında spektrum algılma başarımını artırma…

Dünyada ve ülkemizde ekonominin, nüfusun ve gelişmişlik seviyesinin artmasıyla birlikte üretimin temel girdisi olan enerji ihtiyacı da hızla artmaktadır. Ülkemiz gereksinim duyduğu enerji ihtiyacının tümünü kendi öz kaynakları ile sağlayamamaktadır. Dolayısı…

Fuel cells can be considered as clean, efficient and economic devices for the next power generation. Flow configuration and operating conditions such as temperature, relative humidity and stoichiometric number are key factors for improving cell performance. …

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…

As the world is running out of fossil fuels and the environment is being seriously damaged by the combustion residuals of the internal combustion engines, the world countries have begun to search alternative ways for mobility. Lightweight electric vehicles w…

Variable magnetic fields are widely used in energy production. Two methods can be applied to make the magnetic field variable. The first of these is to apply an alternating current to the insulated conductor on the outer surface of a core. The other is to rota…

One of the most consumed energy sources today is fossil-based fuels. While the reserve of these fuels is declining, it continues to be the main cause of environmental pollution. Due to the influence of environmental factors and increases in fuel costs has acce…

In this article, the influence of the use of three different bricks on the building heat performance is compared for use on wall surfaces as a building construction element. At the beginning of the analysis, the thermal analysis of the building was carried out…

In this paper, a thermal insulation analysis was carried out for a building using paper waste reinforced clay brick as building material. Firstly, the analysis was made using two different normal wall bricks as building material for the sample building. Later,…

This study presents the investigation of thorium utilization in an ADS with Lead-Bismuth Eutectic (LBE) target. To effectively burn thorium, the ThO2 fuel rods cylindrically prepared, and cladded with SiC, are mixed with 233UO2 at volumetric ratio of 1%. These…

Accurate and efficient detection of aircraft at airports is crucial for enhancing airport security, ensuring safe operations, and improving overall air traffic management. As airports grow in complexity and traffic density increases, automated object detection…
