Doing things right in the first time and keeping them consistently is the only idea behind Six Sigma. Its fundamental objective is to achieve customer satisfaction...

In diesem leicht verständlich geschriebenen Buch wird Wert darauf gelegt, dass vor Beginn einer Forschungsarbeit eine exakte Fragestellung und ein optimaler Versuchsplan erarbeitet wird, der u.a. auch den minimalen Versuchsumfang für vorgegebene vertretbare Risiken enthält.

Low temperature hydrogen fuel cells are electrochemical devices which offer a promising alternative to traditional power sources. Fuel cells produce electricity with a reaction of the fuel (hydrogen) and air. Fuel cells have the advantage of being clean; only producing water and heat as by...

Selecting the best input values for the purpose of fitting a metamodel to the response of a computer code presents several issues. Classical designs for physical experiments (DoE) have been developed to deal with noisy responses, while general space filling designs, though being usually...

Piezoelectric ultrasonic motors are superior to electromagnetic micro motors, because their efficiency remains theoretically constant during miniaturization. However, the still relatively recent technology has a considerable unexploited optimisation potential. Numerical structural analysis by...
