This paper studies the energy-saving adaptive robust motion control of a single-rod hydraulic cylinder through the use of programmable valves—a unique combination of five proportional cartridge valves. The programmable valves decouple the meter-in and meter-out flows and provide true cross port regeneration flow which in turn allows tremendous control flexibility. Although at the expense of con...

Acoustic and electroglottographic (EGG) measurements were used to examine voice quality parameters during the production of the rising and falling pitch movements in German. The vowels / / and / / were studied in a single-speaker speech corpus. The acoustic measurements comprised an automatic spectral analysis of the glottal parameters open quotient (OQ), glottal opening (GO), skewness of glott...

From the chemical point of view, wines are aqueous alcoholic solutions containing more than 1000 components that can be present at high concentrations (g L ), but also at trace levels (ng L ). Some of these components determine the organoleptic properties of wines, while others are signi"cant for classifying their origin and/or for checking whether some adulteration has taken place. Concentrati...
