Detection, Measurement and Classification of Discontinuities of Signals Captured with Noise [PDF]

open access: goldAxioms
In this work, we propose an algorithm for the detection, measurement and classification of discontinuities in signals captured with noise. Our approach is based on the Harten’s subcell-resolution approximation adapted to the presence of noise.

Automatic Discontinuity Classification of Wind-turbine Blades Using A-scan-based Convolutional Neural Network [PDF]

open access: diamondJournal of Modern Power Systems and Clean Energy, 2021
Recent development trends in wind power generation have increased the importance of the safe operation of wind-turbine blades (WTBs). To realize this objective, it is essential to inspect WTBs for any defects before they are placed into operation ...

Classification of Gas-dynamic Discontinuities and their Interference Problems [PDF]

open access: hybridResearch Journal of Applied Sciences, Engineering and Technology, 2014
The aim of the study is to give a common classification of gasdynamic discontinuities, shock-wave structures and shock-wave processes. We have considered the classification of gas-dynamic discontinuities, shock- wave processes, shock-wave structures, discontinuity interaction problems. We have considered different classification criteria: thermodynamic,

Natural stone heterogeneities and discontinuities: an overview and proposal of a classification system [PDF]

open access: bronzeBulletin of Engineering Geology and the Environment, 2023
Portugal has a relevant role in natural stone production and trading. The national sector has been trying to follow the requirements of the Fourth Industrial Era, where automation of stone processing operations is necessary to increase productivity, balance the decreasing workforce and reduce stone waste.

Characterization of mechanical discontinuities based on data-driven classification of compressional-wave travel times

open access: bronzeInternational Journal of Rock Mechanics and Mining Sciences, 2021
Abstract Wave propagation and diffusive transport phenomena are influenced by the mechanical discontinuities in material. This study shows that certain bulk properties of the network of low-velocity mechanical discontinuities (e.g. air-filled cracks) in a material can be characterized by processing compressional-wave travel times using ...

Discontinuities in carbonate successions: identification, interpretation and classification of some Italian examples

open access: closedSedimentary Geology, 1995
Abstract The growing use of unconformities as bounding surfaces for new types of stratigraphic units seems not to be matched by a corresponding effort on process-oriented researches on unconformities themselves. This paper aims at giving a contribution to classification and understanding of discontinuities in carbonate successions from the outcrop ...

Whitham modulation theory of defocusing nonlinear Schrödinger equation and the classification and evolutions of solutions with initial discontinuity [PDF]

open access: diamondActa Physica Sinica, 2023
Since the Whitham modulation theory was first proposed in 1965, it has been widely concerned because of its superiority in studying dispersive fluid dynamics and dealing with discontinuous initial value problems. In this paper, the Whitham modulation theory of the defocusing nonlinear Schrödinger equation is developed, and the classification and ...
