This work is part of a project aiming at helping craftsmen to design and characterize their musical instruments. Starting from a given wind instrument shape, our objective consists in choosing the most relevant physical model able to predict the acoustical input impedance of this musical instrument once constructed. The modeling of bells in brass instruments is still problematic as the limits o...

climate change. It suggested that the action plan agreed in Scotland in July “fell far short of a strategy to stop the rise in greenhouse gases in the atmosphere.” Frustration at the lack of action on climate change was expressed by John Lawton, head of Britain’s Royal Commission on Environmental Pollution who, in the wake of hurricane Katrina, criticised US policymakers and told journalists he...

The first section examines four types direct transcriptions and their interpretive Then, argues variations graphic rather than lexical. its context, phrase zhong 延鐘 can be translated “melodic bells,...

The paper presents a method for automatic transcription of recordings of bell chiming performances. Bell chiming is a Slovenian folk music tradition involving performers playing tunes on church bells by holding the clapper and striking the rim of a stationary bell. The tunes played consist of repeated rhythmic patterns into which various changes are included. Because the sounds of bells are inh...

This study examines some of the potential mechanisms of resistance in selected Pieris (Ericaceae) taxa to the Andromeda lace bug, Stephanitis takeyai Drake and Maa, based on differences in resistance to lace bug feeding, and the possible role of leaf parameters such as leaf wax, toughness, nutrient composition, and stomatal characters in plant resistance. Experiments with extracts of leaf-surf...

In the paper it is demonstrated that Bells theorem an unprovable theorem.
