La utilizatión de la palma en Sonora está cambiando, pero el tejido y techado podrían mantenerse como actividades artesanales y fuentes de ingreso sí se accompañan del debido manejo de los recursos naturales y la adecuada comercialización de los productos.Īdovasio, J. Los troncos son usados en la construcción y los frutos son comestibles en algunas partes del estado. Las hojas son empleadas para tejer, lo cual es el mayor uso de las palmas en la región, y para techar y hacer escobas. Sabal uresana es la palma económicamente más importante. Observation participante y entrevistas formates fueron los métodos utilizados para aprender el uso actual de las palmas silvestres en Sonora. En un inventario de mapas topográficos fueron identificados 337 nombres para los palmares, reforzando así el significado cultural de las palmas en esta región. A wide range of specialised applications have been studied, proving that the measurement technique is not only suitable for near-field source localisation purposes but also for vibro-acoustic problems, panel noise contribution analysis, source radiation assessment, intensity vector field mapping and far field localisation.Sabal uresana fue la palma más frecuentemente discutida en los registros históricos publicados para Sonora, México, y la única mencionada desde los documentos escritos más antiguos al presente. ![]() The high flexibility, high resolution, and low cost characteristics of the proposed measurement methodology, along with its short time requirements, define Scan and Paint as an efficient sound visualisation technique for stationary sound fields. It is then possible to directly visualise sound variations across the space in terms of sound pressure, particle velocity or acoustic intensity. The sensor position is extracted by applying automatic colour tracking to each frame of the recorded video. ![]() The proposed technique, Scan and Paint, is based on the acquisition of sound pressure and particle velocity by manually moving a p-u probe (pressure-particle velocity sensor) across a sound field, whilst filming the event with a camera. This thesis explores the foundations of a novel sound field mapping procedure. Traditional methods, however, such as step-by-step measurements or simultaneous multichannel systems, require a significant trade-off between time requirements, flexibility, and cost. Progress in measurement apparatus and the techniques used to display sound and vibration phenomena has provided excellent tools for understanding specific acoustic problems. Sound visualisation techniques have played a key role in the development of acoustics throughout history.
