A short survey of normative properties of possibility distributions [PDF]

open access: yes, 2003
In 2001 Carlsson and Full´er [1] introduced the possibilistic mean value, variance and covariance of fuzzy numbers. In 2003 Full´er and Majlender [4] introduced the notations of crisp weighted possibilistic mean value, variance and covariance of fuzzy

Stochastic quantum dynamics beyond mean-field

open access: yes, 2014
Mean-field approaches where a complex fermionic many-body problem is replaced by an ensemble of independent particles in a self-consistent mean-field can describe many static and dynamical aspects.

Low-Temperature Expansion for a First Order Surface Transition

open access: yes, 1993
The question concerning the possibility of a first order surface transition in a semi--infinite Blume--Capel model is addressed by means of low temperature expansions.

Calculation of Semi-major and Semi-minor Radii and Deformation Parameters for Molybdenum 86-10042Mo  Isotopes

open access: yesIbn Al-Haitham Journal for Pure and Applied Sciences
This study explores the nuclear properties of even-numbered molybdenum () isotopes in the mass range 86 to 100. It focuses on the calculations of fundamental nuclear properties such as distortion coefficients ( and ), electric quadrupole moments (Q₀ ...

Methodology for Developing Hydrological Models Based on an Artificial Neural Network to Establish an Early Warning System in Small Catchments

open access: yesAdvances in Meteorology, 2016
In some situations, there is no possibility of hazard mitigation, especially if the hazard is induced by water. Thus, it is important to prevent consequences via an early warning system (EWS) to announce the possible occurrence of a hazard.

Flotation froth feature analysis using computer vision technology [PDF]

open access: yesE3S Web of Conferences, 2020
The possibility of machine vision application in the field of flotation efficiency evaluation was studied. Algorithm for froth image analysis was developed with aim of obtaining bubble’s size distribution.

Multi-spectroscopic investigation of the structure of single-wall carbon nanotubes

open access: yes, 2003
We present a multispectroscopic structural study of various nanotube samples with different tube diameters. We determine for each sample the mean bundle and tube diameter as well as the tube diameter distribution.

Focusing Vacuum Fluctuations II

open access: yes, 2002
The quantization of the scalar and electromagnetic fields in the presence of a parabolic mirror is further developed in the context of a geometric optics approximation. We extend results in a previous paper to more general geometries, and also correct an

Magnetic Response in a Zigzag Carbon Nanotube

open access: yes, 2012
Magnetic response of interacting electrons in a zigzag carbon nanotube threaded by a magnetic flux is investigated within a Hartree-Fock mean field approach.

Revealing non-classical behaviours in the oscillatory motion of a trapped ion

open access: yes, 2002
The possibility of revealing non-classical behaviours in the dynamics of a trapped ion via measurements of the mean value of suitable operators is reported. In particular we focus on the manifestation known as `` Parity Effect\rq\rq which may be observed
