Andrea Marlen Esser (scanning acoustic microscope).. Quantitative evaluation of material elasticity was further pursued by the invention of the LFBAM (line-focus-beam acoustic microscope).. Since then, the measurement of elastic properties of specimens in a microscopic area has been a central issue. The .(.) method, o

Michael Schefczyk 3 inlet valve clearance values, the standard S-transform is used to produce a time-frequency representations of the vibration signals. The large size of time frequency images is then reduced to a set of lower sizes using two-dimensional non-negative matrix factorization. A multilayers perceptron ne

Mark Alfanonavy, air and automotive sectors. One of the most adopted one is the planetary gearbox since it has an important reduction ratio within compact space. The dynamic behaviour of a such one is very complicated because it possesses several gears in mesh and differs from other types of gearboxes by the f

Robert J. Hartman,Joshua W. BronsonSensitivity analysis is a promising method used for many engineering problems to assess input-output systems based on vibration. In this paper, the formulation of first order sensitivity (FOS) of complex Frequency Response Functions (FRFs) is developed to evaluate the output responses of piezoelectr

Maria Schwartztroller design and the system design are developed and optimized contemporaneously. However, a poorly designed mechanical system will not at any time be able to hand out a good performance by adding a good controller. Furthermore, to design complex systems, the designers have to follow the tradition

The use of this kind of absorber in form of multilayer is generally used to improve their acoustic performance and the attenuation capacity is increased. Such absorber has an acoustic performance varying with their intrinsic and geometrical proprieties (perforati
