air-jet weaving is an advanced weaving method with high efficiency and productivity. it is one of the most widely used methods of weaving in the world. in air-jet filling insertion, the motion of weft yarn is caused by friction between weft yarn and air blown through nozzle. after declamping and subjecting the yarn to air stream, its motion is not active but very complicated and influenced by s...

Separation of Concerns separates requirements such as synchronization and scheduling from the core functionality of the software system. These requirements are often referred to as crosscutting concerns. The implementation of such requirements is scattered throughout the software system, which results in the code-tangling problem Aspect Oriented Programming provides the user with the ability to...

This article presents a method for automatic seam-tracking in friction stir welding (FSW) of lap joints. In this method, tracking is accomplished by weaving the FSW tool back-and-forth perpendicular to the direction of travel during welding and monitoring force and torque signals. Research demonstrates the ability of this method to automatically track weld seam positions. Additionally, tensile ...
