Nowadays, in the field of industry and commerce, heavy loads have to be removed by various methods and moved from one place to another. Mobile cranes in order to overcome these tasks are in common use. One of the problems that prevent the safe and long-lasting…

LEDs that emit blue light are needed to create white light using LEDs. In 1991, Japanese scientists Isamu Akasaki, Hirochi Amano and Shuji Nakamura invented LEDs that emit blue light. From this date it became possible to use the LEDs as lighting elements. Rapi…

The integration of increasing renewable energy-based energy production into the existing electricity grid has become of great importance. The biggest difficulty to integration into the power grid is variability and discontinuity of wind energy. To deal with th…

Developments in Computer Technologies are rapidly spreading all over the world. The internet usage at the beginning of this spread is also manifested in every field. In particular, the use of the internet as a means of communication has made these technologi…

With the effect of globalization, a significant change and transformation have been experienced. As a result of this change, developments in knowledge and information technologies caused an intense competition among both countries and businesses. In such an …
