A Method for Improving the Accuracy of Natural Frequency Measurement Using In-the-loop Computing

open access: yesMeasurement Science Review, 2021
The method presented in the paper is based on in-the-loop computing applied for impulse response to obtain a spectrum with a much higher frequency resolution than using FFT.

Earthquake Response Spectra Analysis of Bridges considering Pounding at Bilateral Beam Ends Based on an Improved Precise Pounding Algorithm

open access: yesShock and Vibration, 2021
Asynchronous vibration was generated between the main bridge and approach spans or abutments due to differences in stiffness and mass during an earthquake, thus further leading to pounding at the bilateral beam ends.

Spectrum-to-spectrum methods for the generation of elastic floor acceleration spectra [PDF]

open access: yes, 2017
In seismic codes, the acceleration demand of nonstructural components is commonly expressed in terms of floor response spectra and estimated by means of simple predictive equations.

Feasibility study on a stabilization method based on full spectrum reallocation for spectra having non-identical momentum features

open access: yesNuclear Engineering and Technology, 2023
Methodology for suppressing or recovering the distorted spectra, which may occur due to mutual non-uniformity and nonlinear response when a multi-detector is simultaneously operated for gamma spectroscopy, is presented with respect to its applicability ...

Diffusion-induced dephasing in nanomechanical resonators [PDF]

open access: yes, 2010
We study resonant response of an underdamped nanomechanical resonator with fluctuating frequency. The fluctuations are due to diffusion of molecules or microparticles along the resonator.

Evaluation methods of elastoplastic response of components to earthquake motions (Dynamic Analysis of MDOF Systems using elastoplastic response spectrum)

open access: yesNihon Kikai Gakkai ronbunshu, 2017
For seismic design of components, elastic response spectrum analysis, which is based on linear response using elastic response spectrum, is generally used as a dynamic analysis of multi-degree-of-freedom(MDOF) systems not only elastic response but also ...

A Data-Driven Building’s Seismic Response Estimation Method Using a Deep Convolutional Neural Network

open access: yesIEEE Access, 2021
As a refined finite element model takes much effort to build and tune to simulate the building structure’s response under seismic effects, many rapid estimation methods were proposed to predict the engineering parameters.

Advances in the RXTE Proportional Counter Array Calibration: Nearing the Statistical Limit [PDF]

open access: yes, 2012
During its 16 years of service the Rossi X-ray Timing Explorer (RXTE) mission has provided an extensive archive of data, which will serve as a primary source of high cadence observations of variable X-ray sources for fast timing studies. It is, therefore,
