Musical Control of a Pipe Based on Acoustic Resonance
In this paper, we introduce a pipe interface that recognizes touch on tone holes by the resonances in the pipe instead of a touch sensor. This work was based on the acoustic principles of woodwind instruments without complex sensors and electronic circuits to develop a simple and durable interface. The measured signals were analyzed to show that different fingerings generate various sounds. The...
متن کاملRisk-cost Approach to Size Detour Culvert
An interim drainage structure provides a short service during the construction months of the permanent drainage structure. This study presents a risk cost approach by which the design flood for an interim drainage structure can be derived from the capacity of the permanent structure, cost-capacity ratio, cost-damage ratio, and construction months during a year. To accommodate various constructi...
متن کاملGlobal opportunities in Pipe in Pipe technology
An extensive product range is mandatory to be a key player in the pipe insulation market. The polyurethane preinsulated pipe producers are responding to global opportunities by diversifying their activities into industrial, marine, oil and gas applications. Moreover, the requirements for traditional district heating preinsulated pipes including initial thermal conductivity and its ageing perfor...
متن کاملSediment concentration and turbidity changes during culvert removals.
The concentrations of sediment and turbidity in stream water were monitored during culvert removals to determine the short term effects of road obliteration. Sediment concentration was measured at 11 stream crossings among two locations in Idaho and one in Washington. Sediment concentration immediately below the culvert outlet exceeded levels above the culvert outlet by at least three orders of...
متن کاملCorner and sloped culvert baffles improve the upstream passage of
Installation of baffles intended to improve fish passage through culverts can reduce discharge capacity and trap debris, increasing flood risk. A sloping upstream face may reduce this risk, but new designs must be tested for fish passage efficiency. The European eel (Anguilla anguilla) is a critically endangered species, yet the suitability of even common baffle types to aid upstream movement h...
