Mechanical similarity as a generalization of scale symmetry

open access: yes, 2005
In this paper we study the symmetry known as mechanical similarity (LMS) and present for any monomial potential. We analyze it in the framework of the Koopman-von Neumann formulation of classical mechanics and prove that in this framework the LMS can be ...

Non-oxide precipitates in additively manufactured austenitic stainless steel

open access: yesScientific Reports, 2021
Precipitates in an austenitic stainless steel fabricated via any Additive Manufacturing (AM), or 3D printing, technique have been widely reported to be only Mn-Si-rich oxides.

A fatigue-reliability approach using ultrasonic non-destructive inspection

open access: yesComptes Rendus. Mécanique, 2023
Fatigue crack propagation can considerably reduce the life of components, leading to sudden failures. This paper provides a method for fatigue life prediction based on ultrasonic non-destructive inspection applied on Al 2024 T3 material.A new crack ...

Performance Analysis of l_0 Norm Constraint Least Mean Square Algorithm

open access: yes, 2013
As one of the recently proposed algorithms for sparse system identification, $l_0$ norm constraint Least Mean Square ($l_0$-LMS) algorithm modifies the cost function of the traditional method with a penalty of tap-weight sparsity. The performance of $l_0$

Persistence pays off: Paying Attention to What the LSTM Gating Mechanism Persists [PDF]

open access: yes, 2018
Language Models (LMs) are important components in several Natural Language Processing systems. Recurrent Neural Network LMs composed of LSTM units, especially those augmented with an external memory, have achieved state-of-the-art results. However, these

Microstructural deformation observed by Mueller polarimetry during traction assay on myocardium samples

open access: yesScientific Reports, 2020
Despite recent advances, the myocardial microstructure remains imperfectly understood. In particular, bundles of cardiomyocytes have been observed but their three-dimensional organisation remains debated and the associated mechanical consequences unknown.

Data Attributes in Quality Monitoring of Manufacturing Processes: The Welding Case

open access: yesApplied Sciences, 2023
Quality monitoring of manufacturing processes is a field where data analytics can thrive. The attributes of the data, denoted with the famous ‘7V’, can be used to potentially measure different aspects of the fact that data analytics may be referred to ...
