The aim of this study was to compare the effect of different cooling conditions (dry, flood, mql) on machined surface parameters (smoothness and protrusion of fibers) and tool erosion in carbon fiber reinforced plastic composite materials (CFRP) in the presence of ultrasonic vibrations or without it. Is. Today, carbon fiber reinforced plastic composite materials or CFRP have become one of the most widely used materials in industry due to their strength and light properties. For example, these materials have been used in the manufacture of products from commercial aircraft to shoes, tennis rackets, golf clubs, fishing rods, etc. The combination of carbon fibers woven with resin in alternating... 

Over recent years, ever increasing developing computer architecture and computer science made increase ability of computers for data processing and creating intelligent systems without human supervision. One of major and important usages of this systems is automatic supervise and analysis on video scene by image and video processing, machine vision and machine learning techniques. Developing this systems and increasing number of installed surveillance cameras on cities made employment of this systems for supervise on urban traffic events.Automatic number plate recognition, anomaly detection, accident detection, traffic sign detection and recognition and etc are example of Intelligent Traffic...
