Simultaneous Material Microstructure Classification and Discovery via Hidden Markov Modeling of Acoustic Emission Signals

Volume 2: Manufacturing Processes; Manufacturing Systems; Nano/Micro/Meso Manufacturing; Quality and Reliability, 2020
Acoustic emission (AE) signals have been widely employed for tracking material properties and structural characteristics. In this study, we aim to analyze the AE signals gathered during a scanning probe lithography process to classify the known ...

Objective microstructure classification by support vector machine (SVM) using a combination of morphological parameters and textural features for low carbon steels

Computational materials science, 2019
The variety of modern steels is growing steadily. In order to meet the ever tighter tolerance ranges for the properties of these steels, it is important to both understand the manufacturing process as accurately as possible and to be able to correctly ...

Automatic Microstructural Classification with Convolutional Neural Network

2018
Microstructural characterization allows knowing the components of a microstructure in order to determine the influence on mechanical properties, such as the maximum load that a body can support before breaking out. In almost all real solutions, microstructures are characterized by human experts, and its automatic identification is still a challenge. In

Microstructure, mineralogy and classification of residual soils

2012
The microstructure and mineralogy of tropical and residual soils are associated with modes of soil formation and occurrence. Microstructure should be considered at two relative scales:1 ped and within-ped or intra-ped voids, 2 grains and intergranular voids.

Microstructural classification of clayey sediments

Geo-Marine Letters, 1991
Progress is being achieved in developing automatic methods of image analysis of electron micrographs for measuring the strength and direction of local preferred orientation, recognition of random areas, and measuring local variations in void ratio and other parameters.

The classification of microstructures of clay soils

Journal of Microscopy, 1980
SUMMARYThis paper presents the results of experimental studies on the microstructure of clay soils, using scanning electron microscopy. Approximately 300 samples of clay soils of various ages, origin and degree of lithification have been analysed. Five main types of microstructure have been identified in clay soils of sedimentary origin, i.e. honeycomb,

Fuzzy classification of microstructural dynamics of human sleep

1996 IEEE International Conference on Systems, Man and Cybernetics. Information Intelligence and Systems (Cat. No.96CH35929), 2002
This work presents an automatic classifier for the microstructural dynamics of human sleep. Microstructure classification is based on phasic and transient events and has several clinical applications in sleep disorders and neurological diseases. The classifier uses EEG activities estimator, fuzzy logic to combine activities and a context based decision

Classification of Market Microstructure Models

2001
Abstract The third chapter contrasts different market microstructure models. In the first group of models, all market participants submit whole demand schedules simultaneously. The traders either act strategically or are price takers as in the competitive Rational Expectations Equilibrium.

Acoustic Scattering Classification of Zooplankton and Microstructure

2000
Abstract : The long-term goal is to understand the acoustic reverberation properties of zooplankton and microstructure. This new understanding will lead to improved capability in 1) predicting sonar performance and 2) use of sonars in the mapping of the zooplankton and microstructure.
