Apparatus for measuring the lateral yarn density distribution of a yarn uses selected radiation in the X-ray spectrum wavelength. Radiation absorption is determined in a number of narrow planes across the yarn and in two or more rotational orientations. The measuring takes place without any damage t.....

The present invention relates to a method for microfluidic mixing in a "lab-on-a-chip" environment. The methodology focuses on constant acceleration and deceleration about a mean angular speed with a rotating disk serving as the mixing platform. The methodology results in good mixing between differe.....

A new multi-function shunt active filter has been successfully implemented. The proposed decoupler and cascade controller provide a simple solution to power factor correction, reduction of harmonics loads and load balancing. The mathematical burden of resolving the load current to fundamental and ha.....
