This study examines the effects of inrush current loads on electric motors operating under low-temperature conditions. While electric motors have a wide range of applications in industrial and military environments, they face significant performance challenges…

Pyrite is a mineral which has very low economic value although it is very common in the world. When the pyrite is concentrated together with the precious minerals, it produces a decrease in the grade and an increase in the smelting costs of the precious minera…

Enerji günümüzün vazgeçilmez ihtiyaçlarından birisidir. İhtiyaca göre farklı tiplerde enerji kaynakları kullanılmaktadır. Ancak fosil kökenli yakıtların tükenebilir enerji kaynakları olması ve çevresel etkenlerden dolayı yenilenebilir enerji kaynaklarının önem…

Environment and climate change caused by human life negatively affects our world on a global scale. The need for sustainable technological solutions to minimize these disadvantages is becoming increasingly imperative. Nanotechnology is entering our lives at th…

Additive manufacturing which is developed in the last half century is promising manufacturing technology. It uses layer-wise production method for obtaining finished product. In recent years, thousand researches were made but there was still gaps about impac…

Taşıtların elektrik ihtiyacı taşıtın cinsine göre her geçen gün artarak devam etmektedir. Bu ihtiyacı karşılamak taşıtlarda bulunan geleneksel elektrik üretim ve depolama yöntemi dışında egzoz ısının geri kazanımı, güneş enerjisi uygulamaları yanı sıra süspa…

The fact that cannot be avoided the non-renewable energy sources (fossil and underground resources) are rapidly depleting, makes the search for new sources of energy extremely important in our country and all over the world. Besides, from past to present, due …

Energy conversion systems are very diverse. One of the most important of these systems is undoubtedly the electric machines. Mechanical energy production from electricity has been ongoing for about 150 years. With rapid developing technology, it has shown a ra…

Low energy and water consumption of green buildings during the life cycle, waste management, minimizing the impact of projects on the ecosystem and increasing the use of environmentally friendly materials have made high performance green buildings attractive…

The aim of this study is to determine instantaneous irradiance and annual percentile sunlit time on the available rooftop floor area of Technical and Social Science Vocational School at Usak University by simulation using open source software. The building of …

Konutlarda enerji tüketiminin artışına karşı yalıtım malzemelerinin kullanımı uzun yıllara dayanan yaygın bir uygulamadır. Yalıtım malzemesinin performansını gösteren en önemli parametre termal iletkenlik katsayısıdır. Termal iletkenlik katsayısını etkileyen, …

In this case study, the shading effect of 480 kW Solar power plant in ilkadım-Samsun was investigated. It is well known that the power generation of photovoltaic systems is significantly influenced by the partial or complete shading of the cells. The substat…

Urban areas have less vegetation than natural environment that surround it. Differences between these types of areas affect climate, energy use, and habitat in cities. In urban areas, dark surfaces and reduced vegetation warm affect the air over urban areas, l…
