This paper presents an interactive design interface for threedimensional free-form musical wind instruments. The sound of a wind instrument is governed by the acoustic resonance as a result of complicated interactions of sound waves and internal geometries of the instrument. Thus, creating an original free-form wind instrument by manual methods is a challenging problem. Our interface provides i...

Introduction Wind scatterometers already flown on ESA’s ERS-1 and ERS-2 satellites have demonstrated the value of such instruments for the global determination of sea-surface wind vectors. These highly successful instruments – part of the Active Microwave Instrument (AMI) – were conceived about twenty years ago. During the intervening period, there has been a considerable evolution in the capab...

Slow and complicated wind power planning and permitting procedures have been a large obstacle for wind power diffusion in Sweden and other countries. This paper complements previous siting-oriented literature with a planning perspective on these problems. The focus is two national planning instruments implemented in Sweden in the early 2000s: a national planning target and an appointment of are...

Planning of wind farms appears to be a complicated matter in Switzerland and all over Europe, causing growing government and business frustration. The implementation often fails on the local level when it comes to choosing a suitable location for a wind farm, although the public generally supports wind power (DEVINE-WRIGHT 2005, WOLSINK, 2005). Social acceptance is a key issue for successful wi...

The structure of thermally coupled distillation systems offers several control challenges arising from the transfer of vapor (or liquid) streams between columns. In particular, the presence of recycle streams for coupled schemes has led to the notion that control problems might be expected during the operation of these systems, in contrast to the rather well-known behavior of conventional disti...
