Methods of monitoring suspended sediment concentration profiles have largely relied on in situ point sampling by water bottles, coupled with optical instrumentation. These intrusive methods can affect the measurements, and optical instrumentation must usu... see more

At this time the research related to the effect of magnetostriction for underwater applications is still limited. Acoustic or sound waves are more easily propagated underwater than electromagnetic waves or light. An acoustic wave or sound can be generated... see more

The acoustic quality in enclosed spaces is defined by the constructive characteristics of the environment, which must be designed to increase the propagation of the sound. Therefore, the sound message to be transmitted, whether spoken, song or by music in... see more

The acoustic emission technique has been considered to be one of the most reliable and robust methods for the measurement of the steady burning rate of composite propellants. In this work, attempts were made to quantify the measurement variability of the ... see more

Environmental pollution and the corresponding control measurements put in place to tackle it play a significant role in determining the actual quality of life in modern cities. Amongst the several pollutant that have to be faced on a daily basis, urban no... see more

Aim of study: Modelling the structural quality of Pinus pinaster Ait. wood on the basis of measurements made on standing trees is essential because of the importance of the species in the Galician forestry and timber industries and the good mechanical pro... see more

Shore-based measurements of near-surface currents are used in a preliminary study of the circulation patterns in a small embayment (width of about 120 m). The measurements were made using an acoustic Doppler current profiler mounted so two acoustic beams ... see more

A 3-year study of water density anomalies within a conventional tide-well indicated that the average water density within the well was consistently lower than that of the external ambient waters. The tide-well at Marrnugao, Goa, India is situated at the m... see more

The authors focus their attention on the identification of the probability distribution density function of the sound level, which constitutes the basis for the proper statistical inferences and uncertainty assessments in the environment acousti­cal hazar... see more
