Ship operators are calling more often for reduced fuel consumption and economic ship operation also in offdesign. The versatile operation profile of ship types such as RoRo-vessels are then a challenge for the design of the propeller and for the propulsion concept. This paper presents aspects on the propeller design and propulsion concept of a ship as well as design methods for the propeller. L...

A new approach to computer music instruments is described. Rather than sense control parameters from acoustic instruments (or non-acoustic instrument controllers), the sound of an acoustic instrument is used directly by a synthesis algorithm, usually replacing an oscillator. Parameters such as amplitude and pitch can control other aspects of the synthesis. This approach gives the player more co...

Nowadays the use of the Switched Reluctance Motors (SRMs) has been considerably increased in various home and industrial applications. Despite of many advantages of this type of motors, such as simple structure, low cost, and high reliability, the main disadvantage of them is the generation of high torque pulsation. This paper presents a novel method to optimize a typical SRM such that the torq...

Sensitivity to static changes in pitch has been shown to be poorer in school-aged children wearing cochlear implants (CIs) than children with normal hearing (NH), but it is unclear whether this is also the case for dynamic changes in pitch. Yet, dynamically changing pitch has considerable ecological relevance in terms of natural speech, particularly aspects such as intonation, emotion, or lexic...
