In the traditional design process, the design starts with preliminary dimensions that may change by using engineering intuition after unfulfillment of necessary design conditions. By this way, the design is renewed with ...
In this research, a scale was developed to determine the programming-oriented computational thinking skills of university students. The participants were 360 students studying in various departments at different universities ...
Turkey owns a very important cultural and historical heritage that bears the traces of thousands of years of culture and civilization. It is an inevitable duty to carry these treasuries to the future generations. In this ...
In this article, we propose a new method for the estimation of the force, which is applied by two fractured parts of the bone on each other at the time of contact, while they are brought closer to each other, and the ...
In this study, an adapted Particle Swarm Optimization (PSO) algorithm is proposed for the inverse kinematic solution of the robot that is designed for reduction in fracture treatment with external fixator and it is applied ...
This paper presents an experimental energetic and exergetic comparison for a heat pump system that can be run in different modes as air to air and air to water. Components of the heat pump do not change when the running ...
