The study presents the tribological behavior of epoxy matrix composites containing two different fillers. Hybrid composites were produced with casting method. The composites contains fillers with different particle sizes (<90µm and in the range of 150-300 µm) …
Current study is related with numerical simulation of a centrifugal pump impeller with the specific speed of nq=13. By the help of computational fluid dynamics (CFD) at different operating points, pump performance rsults (Head-Discharge graph) are obtained. Si…
Deneyim, tarih boyunca birçok düşünür tarafından farklı açılardan değerlendirilerek herhangi bir kavram olmanın ötesinde bilgi edinmenin bir kaynağı olarak görülmüş, bilginin kendisi olarak ele alınmıştır. Dolayısıyla mekânın tanımlanmasında deneyim şarttır ve…
The waste problem has become a non-ignorable issue in apparel industry like other manufacturing industries and the concept of sustainability has come to the forefront. The term ‘sustainability’ refers to the long-term viability of business operations and their…
In this study, we focused on to drive a compound DC motor with a Fuel-Cell and battery, which uses hydrogen as a fuel. A fuel cell can supply maximum 40V electric. In order to drive a DC motor, it needs 200Vdc. Therefore, a microcontroller controlled boost con…
Bu çalışmada, haberleşme cihazlarının (telefon, tablet, bilgisayar) kullanımı için ihtiyaç duyulan elektrik enerjisinin temini güneş enerjisi kullanılarak sağlanmaya çalışılmıştır. Elektrik enerjisinin olmadığı ortamlarda bu elektronik cihazlar tasarlanmış ola…
In this study, an experimental investigation of electricity production from a thermoelectric cooler heated by solar energy heat pipe has been done. For this, a heat pipe with water as the working fluid has been manufactured. Approximately 300 ml of water stora…
In this study, the effect of still water cooling on electricity generation in a thermoelectric generator heated by solar energy heat pipe is experimentally investigated. For this purpose, a heat pipe with ethyl alcohol as the working fluid has been manufacture…
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,…
Kablosuz ağlar, veri sinyallerinin havadan iletildiği, kablo kullanmadan uzak mesafeler arasında iletişimi sağlayabilen teknolojilerdir. Kablosuz ağlarda veri, radyo frekansları veya kızılötesi ışınlar vasıtasıyla iletilir. Bu ağlardaki kullanıcılar arasında h…
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…
The aim of this study is to forecast installed wind power which is a one of the renewable energy resources in Turkey for the year of 2017 based on artificial neural network method using the normalized last ten-year data. An artificial neural network has been c…
Exhaust gas distribution in street canyons is one of the important research subjects in urban air quality studies. Vehicle emissions are an important group of pollutants in urban areas. In this study, the dispersion of exhaust emissions from vehicles in canyon…
In this study, the accelerations caused by the diaphragm movements during respiration were monitored with a 3-axis accelerometer and the measured accelerations were recorded on an SD card. A measurement system for this purpose was developed. The moments in whi…
