High-resolution modal analysis

TL;DR: The Ashby diagram presented here, built from data available in the literature, constitutes a first tool for selecting materials considering the compromise between the loss factor and stiffness for engineering design considerations.

TL;DR: Ege et al. as discussed by the authors measured the nonlinear part of the soundboard response to an external excitation at ≈ − 40 dB below the linear part at the ff nuance.

TL;DR: In this article, the modal density of the soundboard of an upright piano in playing condition, as seen from various points of the structure, exhibits two well-separated regimes, below and above a frequency f lim that is determined by the wood characteristics and by the distance between ribs.

TL;DR: The High Resolution Wavevector analysis (HRWA) as mentioned in this paper is a wavevector analysis method that uses the high resolution signal processing algorithm ESPRIT (Estimation of Signal Parameters via Rotational Invariance Techniques) and the ESTER criterion (ESTimation of ERror) to overcome some of the limitation of Fourier-based methods.

TL;DR: Although discussed in the context of direction-of-arrival estimation, ESPRIT can be applied to a wide variety of problems including accurate detection and estimation of sinusoids in noise.

TL;DR: A novel approach to the general problem of signal parameter estimation is described, and although discussed in the context of direction-of-arrival estimation, ESPRIT can be applied to a wide variety of problems.

TL;DR: A Treatise on the Mathematical Theory of Elasticity by A. E. Love as discussed by the authors is the necessary complement to Todhunter and Pearson's history of the theory of elasticity, in which an abstract is given of all the most important original memoirs bearing on this subject, arranged in historical order.
