Abstract The influences of processing parameters and tool feature on the microstructure AA1100 AA3003 aluminium alloys were investigated using bobbin friction stir welding (BFSW). research includes flow visualization microstructural evolution weld texture metallographic measurement method. Results indicated that operational (e.g. feed rate, rotating speed) geometry can directly affect patterns ...

The proposed paper presents optoelectronic sensors for detection of a lack of thread in two types of textile machines. Possible reasons for this failure may be thread breaks or running out of material in the supply bobbin. The application of this method results in a rapid and timely stop of the workflow and reduces the time for restoring the operation of machines. This leads to an increase in l...

A new type detection device for the suspended flyer was developed to test the press finger and performance parameters of the flyer. The device was made up of mechanical transmission, control and signal processing part, which realized full automation of measurement by wireless transmission technology. Hybrid driven differential adjustable framework was employed in the device, so the bobbin windi...

Today some embedded systems still do not integrate their own floating-point unit, for area, cost, or energy consumptionconstraints. However, this kind of architectures is widely used in application domains highly demanding on floating-point calculations (multimedia, audio and video, or telecommunications). To compensate this lack of floating-pointhardware, floating-point arithmetic ...
