Gelişen teknoloji ve artan nüfusun etkisiyle enerji tüketimi giderek artmaktadır ve bu durum tüm dünyada olduğu gibi ülkemizde de önemli bir problem olarak karşımıza çıkmaktadır. Fosil enerji kaynakları gün geçtikçe azalmaktadır ve bu nedenle araştırmacılar …

Forest workers generally work under severe conditions. Wood work; far from social spaces, weather conditions and rugged terrain. There is also no room for errors that are connected to a plan. Accident risk is high in forest workers. Accident risk must be hig…

Asynchronous motors are the most preferred engines in the industry due to factors such as their stable speed, economic and operational safety. Recently, asynchronous motors have been used as generators in the power generation sector and especially in wind turb…

Analog filters have an important role in modern communication systems. Filter circuits with low noise, which occupy less chip area and consume less power as well as operate in the high-frequency region, are required with the developing technology. In the liter…

In today’s developing world, capital needs, which are essential to fulfill an enterprise, still pose a problem despite the subsidies and special funds. The aim of this study is to analyze to what extent the subsidies of SMIDO in Tokat province, which is situa…

Nowadays, there are old and new methods that involve the difficult problems and solution suggestions which many researchers research and try to solve. In the field of engineering, the success rates of the methods that produce solutions to these problems are of…

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…
