Backflow air and pressure analysis in emptying a pipeline containing an entrapped air pocket
(Taylor and Francis Ltd., 2018)The prediction of the pressure inside the air pocket in water pipelines has been the topic for a lot of research works. Several aspects in this field have been discussed, such as the filling and the emptying procedures. ... -
Background intensity removal in Fourier transform profilometry: A comparative study
(OSA - The Optical Society, 2016)We study the removal of the background intensity of fringe patterns via Empirical Mode Decomposition and the Hilbert Transform. Simulation results show that the latter provides a suitable background compensation with minimal ... -
Background intensity removal in structured light three-dimensional reconstruction
(Institute of Electrical and Electronics Engineers Inc., 2016)In Fourier Transform Profilometry, a filtering procedure is performed to separate the desired information (first order spectrum) from other unwanted contributions such as the background component (zero-order spectrum). ... -
Beer snobs do exist: Estimation of beer demand by type
(Colorado State University, 2014)Although mass-produced beers still represent the vast majority of U.S. beer sales, there has been a significant growth trend in the craft beer segment. This study analyzes the demand for beer as a differentiated product ... -
