Probing Supernovae through gravitational wave entropy

Aknur Sakan, Nurzhan Ussipov, Ernazar B. Abdikamalov, Almat Akhmetali et autres

We study an entropy-based framework to analyze gravitational-wave signals from core-collapse supernovae. We use waveforms generated by numerical simulations and analyze them in both the time domain and the time-frequency domain using short-time Fourier and continuous wavelet transforms. From each representation, we …

Assessing the Distance for Probing the Nuclear Equation of State with Supernova Gravitational Waves

Y. Sultan Abylkairov, Matthew Edwards, Artyom Ostrikov, Yersultan Tleukhanov et autres

Gravitational waves from core-collapse supernovae provide a unique probe of the equation of state (EOS) of high density matter. In this work, we focus on the bounce signal from numerical simulations of rotating supernovae and explore its potential for EOS inference. We …

Evaluating machine learning models for supernova gravitational wave signal classification

Y. Sultan Abylkairov, Matthew Edwards, Daniil Orel, Ayan Mitra et autres

Abstract We investigate the potential of using gravitational wave (GW) signals from rotating core-collapse supernovae to probe the equation of state (EOS) of nuclear matter. By generating GW signals from simulations with various EOSs, we train machine learning models to classify them …

A novel stacked hybrid autoencoder for imputing LISA data gaps

Ruiting Mao, Jeong Eun Lee, Matthew Edwards

The Laser Interferometer Space Antenna (LISA) data stream will contain gaps with missing or unusable data due to antenna repointing, orbital corrections, instrument malfunctions, and unknown random processes. We introduce a new deep learning model to impute data gaps in the LISA …

Preliminary rolling noise measurements toward the design of a standard rolling noise device

Matthew Edwards, Raimundo González Diaz, Nadia Dallaji, Luc Jaouen et autres

The tapping machine has long existed as the primary standard method for measuring the performance of floors in buildings in response to structure-borne noise. However, other sources of structure-borne noise exist. One of these is rolling noise: such as a trolley rolling …

Prévision et contrôle du bruit de roulement dans les bâtiments

Matthew Edwards

Les nouveaux bâtiments dans les zones urbaines sont divisés en zones commerciales et en zones habitables. Les magasins commerciaux se trouvent généralement au rez-de-chaussée, les résidences privées aux étages supérieurs. Cette utilisation a révélé des perturbations critiques dues au bruit généré par …

Recommendation for a Standard Rolling Noise Machine

Matthew Edwards, Raimundo González Diaz, Nadia Dallaji, Luc Jaouen

In the world of building acoustics, a standard tapping machine has long existed for the purpose of replicating and regulating impact noise. However there still exist other kinds of structure-borne noise which could benefit from being considered when designing a building. One …

Polynomial relations for cylindrical wheel stiffness characterization for use in a rolling noise prediction model

Matthew Edwards, Fabien Chevillotte, François‐Xavier Bécot, Luc Jaouen et autres

In vehicle tire/road contact modeling, dynamic models are typically used which incorporate the vehicle’s suspension in their estimation: thus relying on a known stiffness to determine the movement of the wheel in response to roughness excitation. For the case of a wheeled …

Prediction and control of rolling noise in buildings

Matthew Edwards

New buildings in urban areas are divided into commercial and residential areas. Commercial stores are generally located on the ground floor, private residences on the upper floors. This use has revealed critical disturbances due to noise generated by delivery carts when buildings …
