Frequency-Zooming ARMA Modeling for Analysis of Noisy String Instrument Tones
EURASIP Journal on Advances in Signal Processing, 2003 This paper addresses model-based analysis of string instrument sounds. In particular, it reviews the application of autoregressive (AR) modeling to sound analysis/synthesis purposes.

A novel implementation of method of optimality criterion in synthesizing spacecraft structures with natural frequency constraints [PDF]
In the design of spacecraft structures, fine tuning the structure to achieve minimum weight with natural frequency constraints is a time consuming process. Here, a novel implementation of the method of optimality criterion (OC) is developed.

Broadband Multizone Sound Rendering by Jointly Optimizing the Sound Pressure and Particle Velocity
, 2017 In this paper, a recently proposed approach to multizone sound field synthesis, referred to as Joint Pressure and Velocity Matching (JPVM), is investigated analytically using a spherical harmonics representation of the sound field.

A Modified Nonlinear Modal Synthesis Scheme for Mistuned Blisks with Synchronized Switch Damping
International Journal of Aerospace Engineering, 2018 In the authors’ previous work (MSSP 2017), we show that the synchronized switch damping based on negative capacitor (SSDNC) is a good candidate for vibration suppression of tuned blisks.

Average-cost based robust structural control [PDF]
A method is presented for the synthesis of robust controllers for linear time invariant structural systems with parameterized uncertainty. The method involves minimizing quantities related to the quadratic cost (H2-norm) averaged over a set of systems ...

DEStech Transactions on Engineering and Technology Research, 2017 The large deviation between test results and real conditions caused by the coupling of test fixture is unavoidable. The research on free interface modal synthesis method can gain the modal test boundary transformation of one missile wing. For this purpose, the low order normal mode spectrum matrix and mode shapes was gained by free modal test, the ...
