Process design involving ultrasound
(WILEY-BLACKWELL, 2012-04)
Capítol de llibre
Accés restringit per política de l'editorial -
Quartz crystal microbalance holder design for on-line sensing in liquid applications
(2016-05)
Article
Accés obertIn this paper, the design of a QCM sensor for liquid media measurements in vertical position is described. A rugged and low-cost proof holder has been designed, the cost of which is significantly lower than those ... -
Real-time detection of the bacterial biofilm formation stages using QCM-based sensors
(2023-01-14)
Article
Accés obertBacterial biofilms are a major cause of harm related to medical infections and biofouling. Thus, 80% of total infections are caused by biofilm-forming microorganisms. Consequently, knowledge of biofilm formation stages is ... -
Resizing buffer rods for ultrasound testing of food products with acoustic noise considerations
(2013-01)
Article
Accés restringit per política de l'editorialBuffer rods can be used to perform non-destructive and on-line analysis of food and beverage products. These rods, usually solid cylinders, can be long and heavy for certain applications. In this paper, a resizing analytic ... -
Splitting of the ultrasounic beam path in clamp-on ultrasonic flowmeters due to propagation through dispersive materials
(Institute of Electrical and Electronics Engineers (IEEE), 2017)
Text en actes de congrés
Accés restringit per política de l'editorialThis article explains how a multi-frequency ultrasonic beam path is split due to passing through dispersive materials and the implications that it has in flow measurement using a Clamp-on ultrasonic flowmeter. The importance ... -
Study of the effect of angle errors in conical ultrasonic sensors
(2013-09-01)
Article
Accés restringit per política de l'editorialMany ultrasonic sensors intended for non-destructive testing include a plastic or metal element, known as buffer rod, between the ultrasonic transducer and the material under analysis. Buffer rods are often terminated in ... -
Temperature compensation of ultrasonic velocity during the malolactic fermentation process
(2015-11-04)
Article
Accés obertUltrasonic properties of materials present a strong dependence on temperature and in turn the ultrasonic velocity of propagation in the material under test. It is precisely for this reason that most ultrasonic measurements ... -
Ultrasonic inspection system for powder metallurgy parts
(2013-04)
Article
Accés restringit per política de l'editorialThe demand for powder metallurgy (P/M) parts in its traditional automotive market is predicted to grow, but future sector expansion depends directly upon its capability to manufacture zero-defect parts for industries such ... -
Ultrasonic monitoring of malolactic fermentation in red wines
(2014-08-01)
Article
Accés restringit per política de l'editorialThe progress of malolactic fermentation in red wines has been monitored by using ultrasonic techniques. The evolution of ultrasonic velocity of a tone burst 1 MHz longitudinal wave was measured, analyzed and compared to ... -
Ultrasonic velocity of water-ethanol-malic acid-lactic acid mixtures during the malolactic fermentation process
(Elsevier, 2015-03)
Article
Accés obertDuring malolactic fermentation in wines, malic acid is transformed into lactic acid by the action of lactic acid bacteria. This process can be monitored on-line by measuring the velocity of a low intensity ultrasonic wave ... -
Zero-flow offset variation in ultrasonic clamp-on flowmeters due to inhomogeneity and nonlinearity of pipe materials
(2017-11)
Article
Accés restringit per política de l'editorialThe objective of this paper is to measure the zero-flow offset variation in ultrasonic Clamp-on flowmeters produced by using pipes made of materials with a nonhomogeneous and nonlinear behavior. The evaluation of this ...
