In this paper, a symmetric gyro with coupling to the tip mass of a beam mounted on a vibrating base is considered. Taking advantage of the angular momentum of the rotating gyroscope, gyrostabilizer systems are expected to ...

Ni–B/SiO2, Al2O3, TiO2 and CuO composite coatings were successfully obtained by the electroless plating technique. Dispersible SiO2, Al2O3, TiO2 and CuO nanoparticles were co-deposited with electroless Ni–B coating onto ...

Today, especially in many fields that require structural durability, such as the aerospace and automotive industries, there has been a need to use different bonding techniques separately or together in order to use materials ...

This study investigates the use of dimethyl ether and diethyl ether in diesel engines as alternative fuels. A direct injection diesel engine was simulated via a thermodynamic cycle model for investigation. Thermodynamic ...

Tuğla, çok eski zamanlardan beri binalarda yapı malzemesi olarak kullanılmaktadır. Dış ortamla yaşam alanlarını birbirinden ayıran tuğla, ısı transferi açısından da önemli bir özelliğe sahiptir. Gelişen teknolojiye ve ...

The study performs energy and exergy analyses for each component such as boilers, buildings, distribution networks and heat exchangers of a new generation district heating system. Energy and exergy efficiencies are compared ...

The efficiency of thorough anodic oxidation of ASTM A356 aluminum alloy as an alternative to painting its surface is studied. Microstructure, phase composition, and microhardness of oxidized layers of various thicknesses ...
