The Size and Shape of Voids in Three-Dimensional Galaxy Surveys [PDF]
, 2000 The sizes and shapes of voids in a galaxy survey depend not only on the physics of structure formation, but also on the sampling density of the survey and on the algorithm used to define voids.

On the role of shear in cosmological averaging [PDF]
, 2010 Using the spherically symmetric inhomogeneous Lemaitre-Tolman-Bondi dust solution, we study how the shear and the backreaction depend on the sharpness of the spatial transition between voids and walls and on the size of the voids.

Phase field modelling voids nucleation and growth in binary systems
Condensed Matter Physics, 2018 We present a comprehensive study of voids formation, nucleation and growth in a prototype model of binary alloys subjected to irradiation by using a combined approach based on phase field and rate theories.

Analysis of Failure Mode of Reinforced Embankments Overlying Voids Based on Discrete Method
Applied Sciences, 2023 The mode of the reinforced embankment overlying voids was generated based on discrete element software. By changing the vertical distance H and the horizontal distance L, the influence of the void position on the bearing capacity characteristics ...

Voids in the Cosmic Web as a probe of dark energy
Condensed Matter Physics, 2017 The formation of large voids in the Cosmic Web from the initial adiabatic cosmological perturbations of space-time metric, density and velocity of matter is investigated in cosmological model with the dynamical dark energy accelerating expansion of the ...

On the observability of coupled dark energy with cosmic voids [PDF]
, 2014 Taking N-body simulations with volumes and particle densities tuned to match the SDSS DR7 spectroscopic main sample, we assess the ability of current void catalogs (e.g., Sutter et al. 2012b) to distinguish a model of coupled dark matter-dark energy from

Outcomes of Class II composite restorations placed by dental students: An observational study
Saudi Journal of Oral Sciences, 2020 Introduction: Main objectives of restoring the teeth is to remove the caries and replace the tooth structure to restore form and function. This radiographic study aimed to determine the defective Class II composite restorations in permanent teeth placed ...

Advanced Manufacturing: Polymer & Composites Science, 2021 In the present work, cross-ply and multidirectional laminates were produced by autoclave moulding. Changes in the process parameters led to different microstructural features in terms of fibre volume fraction, global void content, and void size.
