Sabit mıknatıslı senkron generatörlerin modellenmesi ve optimizasyonu Modelling and optimization of permant magnet synchronous generators

Nergiz, Erhan

ÖZETGelişen teknoloji ve sanayileşme ile birlikte, enerji ihtiyacı her geçen gün artmaktadır. Bu ihtiyacın büyük bir kısmı fosil yakıtlı santrallerden karşılanmaktadır. Fakat fosil yakıtların çevreye verdiği zararlar ve ömürlerinin de her geçen gün azalması, alternatif enerji kaynakları ile ilgili çalışmaların artmasına neden olmuştur. Bu enerji kaynaklarının en önemlileri rüzgâr türbinleri, güneş enerjisi santralleri, hidroelektrik santraller, jeotermal enerji ve biyoenerji tesisleridir. Sabit mıknatıslı senkron generatörler (SMSG), özellikle D-D rüzgar türbinlerinde, hidroelektrik santraller ...Daha fazlası

Development of 3D-Printed plastic based low-cost sensing systems 3D baskılı plastik bazlı düşük maliyetli algılama sistemlerinin geliştirilmesi

Bayram, Abdullah

ABSTRACTEnvironment and health is two important things that are so important to human lifebecause they cannot be separated from each other. The problems related with thesetwo events will negatively affect human life. Therefore, health and environmentalproblems should be monitored with proper testing devices and analyzed. In order toperform these tests, we need cheap, reliable and fast test equipment. With therevolution of three-dimensional (3D) printing technology that is cheap, practical, fastmethod of production, this kind of test devices can be produced. This productionmethod is used to pro ...Daha fazlası

Preparation and characterization of carbon-based nanofluids Karbon bazlı nanoakışkanların hazırlanması ve karakterizasyonu

Fidan-Aslan, Tuğçe

ABSTRACTNanofluids are produced by the addition of nano-sized particles to the base fluid in order to increase the thermal conductivity of heat transfer fluids. Preparation of stable nanofluids with high thermal conductivity is a very complex process and their usage in heat transfer applications are related to many important parameters from the stability of nanofluids to their viscosity. Optimization of these parameters is essential for the practical use of nanofluids. The objectives of this study are to successfully preparecarbon-based nanofluids while investigating the stability mechanisms a ...Daha fazlası

Kaya, Nusret

ABSTRACTElectronic industry is growing dramatically in the last quarter of the century. Recent advances in electronics industry enable the miniaturization of micro transistors and the integration of more transistors into the electronic devices, resulting in a higher performance device. However, this condition increases the heat flow in the electronic devices. The performance of electronic devices depend on the working temperature, for this reason, it is important to remove the heat produced in the device as fast and efficiently as possible in order to hold the system temperature of the electro ...Daha fazlası

Selek, Mehmet Hakan

ABSTRACTPreterm newborns are unlikely to live without any additional support. Babies born in this way need special care and a place that would imitate their mother’s womb as much as possible. The environmental conditions like the temperature, humidity, noise, light intensity, etc. need to be carefully managed. In addition to managing the environment, it is necessary to record vital data such as baby's temperature and pulse and record any changes so that they can be examined later. Since the systems that carry out these mentioned controls are very expensive, there are still hospitals that do no ...Daha fazlası
