Motion analysis of the hyoid bone via videofluoroscopic study has been used in clinical research, but the classical manual tracking method is generally labor intensive and time consuming. Although some automatic tracking methods have been developed, masked points could not be tracked and smoothing and segmentation, which are necessary for functional motion analysis prior to registration, were n...

Abstract In this paper a promising novel output voltage filtering concept for multi-cell switch-mode power amplifiers is analyzed. The proposed hybrid filtering concept is based on a passive LC filter enhanced by a linear-mode correction stage of small rated power. Using this principle, also "sub-harmonic" (i.e. low-frequency) switching noise distortions (typically appearing in real interleaved...

We have demonstrated both rise and fall times below 1 s with 10%–90% modulation in a silicon-on-insulator thermooptical Mach–Zehnder switch. The switch is based on 9m-thick and 10m-wide single-mode rib waveguides. Very fast switching was achieved by using a differential control method. The switch was driven with a digital signal processor accompanied by simple electronic circuitry.

The number of road accidents is increasing due to the power outage traffic light system and streetlight system's maintenance fees was too high. Therefore, a proposed solution that includes automatic controller, energy-saving controller energy transfer switch had been designed overcome these issues. on four-way junction which has one sensor for each direction. This 3 different conditions will ac...
