The separation of Hydrogen Isotopes via Modified Metal Organic Frameworks [PDF]

open access: yesمجله علوم و فنون هسته‌ای, 2023
Hydrogen isotope separation can be achieved by confinement to small mesoporous structures or by strong adsorption sites. MOFs are attractive candidates for isotope separation, considering their tunable pore structures and the potential to introduce ...

Fixed/Preassigned-Time Synchronization of Fully Quaternion-Valued Cohen–Grossberg Neural Networks with Generalized Time Delay

open access: yesMathematics, 2023
This article is concerned with fixed-time synchronization and preassigned-time synchronization of Cohen–Grossberg quaternion-valued neural networks with discontinuous activation functions and generalized time-varying delays.

A Multi-Source Separation Approach Based on DOA Cue and DNN

open access: yesApplied Sciences, 2022
Multiple sound source separation in a reverberant environment has become popular in recent years. To improve the quality of the separated signal in a reverberant environment, a separation method based on a DOA cue and a deep neural network (DNN) is ...

UNSUPERVISED STATISTICAL APPROACH FOR TREE-LEVEL SEPARATION OF FOLIAGE AND NON-LEAF COMPONENTS FROM POINT CLOUDS [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2023
Accurately classifying foliage and non-leaf components in point clouds is essential for remote sensing forest applications. Existing methods rely on radiometric attributes or local geometric features, often requiring time-consuming manual labelling.

Pre-concentration of Some Heavy Metals using cloud point extraction

open access: yesمجلة علوم ذي قار, 2022
Heavy metals are usually present in trace amounts in real samples such as natural waters, soil and plants samples but many of them are toxic even at very low concentrations, therefore, cloud point extraction (CPE) used for heavy metal separation.

Boundary-layer separation in circular diffuser flows in the presence of an external non-uniform magnetic field [PDF]

open access: yesMechanical Sciences, 2020
The focus of the present work is on the investigation of the separation point and its relative location in a circular diffuser carrying incompressible laminar flow in the presence of a non-uniform external magnetic field.

Parametric Stochastic Modeling of Particle Descriptor Vectors for Studying the Influence of Ultrafine Particle Wettability and Morphology on Flotation-Based Separation Behavior

open access: yesPowders, 2023
Practically all particle separation processes depend on more than one particulate property. In the case of the industrially important froth flotation separation, these properties concern wettability, composition, size and shape.

Continuous Particle Separation Driven by 3D Ag-PDMS Electrodes with Dielectric Electrophoretic Force Coupled with Inertia Force

open access: yesMicromachines, 2022
Cell separation has become @important in biological and medical applications. Dielectrophoresis (DEP) is widely used due to the advantages it offers, such as the lack of a requirement for biological markers and the fact that it involves no damage to ...

Effects of non-uniform weeping distributions on tray and point efficiencies

open access: yesResults in Engineering, 2023
Weeping is known to significantly reduce tray and point efficiencies in distillation tray columns. When designing distillation columns, conservative rules of thumb are applied to account for the effect of weeping on separation efficiency, while assuming ...

Activity-induced phase transition in a quantum many-body system

open access: yesPhysical Review Research, 2022
A crowd of nonequilibrium entities can show phase transition behaviors that are prohibited in conventional equilibrium setups. An interesting question is whether similar activity-driven phase transitions also occur in pure quantum systems.
