چکیده
Abstract The aim of a transfer path analysis (TPA) is to view the transmission vibrations in mechanical system from point excitation over interface points reference point. For that matter, Frequency Response Functions (FRF) or Transmissibility Matrix determined and examined conjunction with forces at path. This paper will cover application an operational TPA for wind turbine model. In doing so contribution relevant paths are made visible can be optimized individually.

An Improved Transfer Logic of the Two-Path Algorithm for Acoustic Echo Cancellation
Adaptive echo cancellers with two-path algorithm are applied to avoid the false adaptation during the double-talk situation. In the two-path algorithm, several transfer logic solutions have been proposed to control the filter update. This paper presents an improved transfer logic solution. It improves the convergence speed of the two-path algorithm, and allows the reduction of the memory elemen...
متن کاملMinimum path bases and relevant paths
Given an undirected graph G(V, E) and a vertex subset U ⊆ V the U space is the vector space over GF(2) spanned by the paths with end-points in U and the cycles in G(V, E). We extend Vismara’s algorithm to the computation of the union of all minimum length bases of the U -space. While the size distribution of subgraphs is the same in all minimum length bases, the number of cycles and paths may d...
متن کاملMomentum transfer for momentum transfer-free which-path experiments
Bohr’s principle of complementarity constitutes the hallmark and one of the most intriguing features of quantum mechanics. On the basis of this principle [1, 2] it is indeed universally accepted that any devices capable of determining the path taken by a particle trough a Young like double-aperture must destroy the interference. The justification usually presented is based on Heisenberg’s uncer...
متن کاملAn experimental method for measuring transfer functions of acoustic tubes
This work proposes an experimental method for direct measurement of transfer functions of acoustic tubes. The method obtains a pressure-to-velocity transfer function from measurement of input volume velocity and output pressures of a target tube. Steady sinusoidal waves from 100 Hz to 5 kHz with a 10-Hz increment were used as a source signal. Experimental results compared with transmission line...
متن کاملRapid identification of clinically relevant Legionella spp. by analysis of transfer DNA intergenic spacer length polymorphism.
Analysis of PCR-amplified transfer DNA (tDNA) intergenic spacers was evaluated as a rapid method for identification to the species level of 18 species of Legionella known as human pathogens. Type strains (n = 19), reference strains (n = 16), environmental strains (n = 31), and clinical strains (n = 32) were tested. PCR products using outwardly directed tDNA consensus primers were separated on p...
