Three-Dimensional Volume Integral Equation Method for Solving Isotropic/Anisotropic Inhomogeneity Problems

open access: yesMathematics, 2020
In this paper, the volume integral equation method (VIEM) is introduced for the analysis of an unbounded isotropic solid composed of multiple isotropic/anisotropic inhomogeneities.

Neurogeometry of Perception: Isotropic and Anisotropic Aspects [PDF]

open access: yesAxiomathes, 2019
In this paper we first recall the definition of geometical model of the visual cortex, focusing in particular on the geometrical properties of horizontal cortical connectivity. Then we recognize that histograms of edges - co-occurrences are not isotropic distributed, and are strongly biased in horizontal and vertical directions of the stimulus. Finally

A generalized approach for the determination of optimum tilt angle for solar photovoltaic modules with selected locations in Ethiopia as illustration examples

open access: yesScientific African, 2022
The amount of total solar energy that strikes the photovoltaic module's surface directly affects how much power is generated. On the other hand, solar energy is influenced by the solar module's location, tilt angle, and orientation.

Multidimensional isotropic and anisotropicq-oscillator models [PDF]

open access: yesJournal of Physics A: Mathematical and General, 1996
q-oscillator models are considered in two and higher dimensions and their symmetries are explored. New symmetries are found for both isotropic and anisotropic cases. Applications to the spectra of triatomic molecules and superdeformed nuclei are discussed.

Cracking isotropic and anisotropic relativistic spheres [PDF]

open access: yesCanadian Journal of Physics, 2017
We explore the influence of density fluctuations on isotropic and anisotropic configurations, extending the concept of cracking for isotropic general relativistic fluid spheres. This concept, conceived to describe the behaviour of anisotropic matter distributions just after its departure from equilibrium, could provide some insight on potential ...

Consequences of anisotropy in electrical charge storage: application to the characterization by the mirror method of TiO2 rutile [PDF]

open access: yes, 2008
This article is devoted first to anisotropic distributions of stored electric charges in isotropic materials, second to charge trapping and induced electrostatic potential in anisotropic dielectrics.

Instability zones for isotropic and anisotropic multibladed rotor configurations [PDF]

open access: yesMechanism and Machine Theory, 2011
Helicopter ground resonance is an unstable dynamic phenomenon which can lead to the total destruction of the aircraft during take-off or landing phases. The earliest research in this domain was carried out by Coleman and Feingold during the decade of 60s.
