Instanton size distribution [PDF]

open access: yesPhysics Letters B, 2000
Abstract By studying the non-linear effects of overlapping instanton pairs we address difficulties in the identification of instanton distributions when the average instanton size is comparable to the average distance. For the exact charge two solution, we study how its parametrisation relates to a description in terms of individual instantons. There

Pore size distribution mapping [PDF]

open access: yesMagnetic Resonance Imaging, 1996
Pore size distribution mapping has been demonstrated using NMR cryoporometry in the presence of a magnetic field gradient. This novel method is extendable to 2D and 3D mapping. It offers a unique nondestructive method of obtaining full pore-size distributions in the range 3 to 100 nm at any point within a bulk sample.

Particle Size Distribution in Aluminum Manufacturing Facilities. [PDF]

open access: yes, 2014
As part of exposure assessment for an ongoing epidemiologic study of heart disease and fine particle exposures in aluminum industry, area particle samples were collected in production facilities to assess instrument reliability and particle size ...

Size-dependent bandgap and particle size distribution of colloidal semiconductor nanocrystals [PDF]

open access: yes, 2017
A new analytical expression for the size-dependent bandgap of colloidal semiconductor nanocrystals is proposed within the framework of the finite-depth square-well effective mass approximation in order to provide a quantitative description of the quantum

Droplet size distribution in homogeneous isotropic turbulence [PDF]

open access: yes, 2011
We study the physics of droplet breakup in a statistically stationary homogeneous and isotropic turbulent flow by means of high resolution numerical investigations based on the multicomponent lattice Boltzmann method.

Synthesized grain size distribution in the interstellar medium [PDF]

open access: yes, 2012
We examine a synthetic way of constructing the grain size distribution in the interstellar medium (ISM). First we formulate a synthetic grain size distribution composed of three grain size distributions processed with the following mechanisms that govern

Size distribution and anti-trust [PDF]

open access: yes, 2000
Extensive literature notwithstanding, effects of the size distribution of firms on consumers’ surplus and on social welfare leaves room for further exploration. In this paper we discover that size distribution imposes two counter-balancing effects on aggregate surplus of the industry : [i] even distribution of firm sizes typically facilitates tacit ...

Beyond morphological size distribution [PDF]

open access: yesJournal of Electronic Imaging, 2009
In the field of digital image processing, the description of image content is one of the most crucial tasks. Indeed, it is a mandatory step for various applications, such as industrial vision, medical imaging, content-based image retrieval, etc. The description of the image content is achieved through the computation of some predefined features, which ...

General expression for the component size distribution in infinite configuration networks [PDF]

open access: yes, 2017
In the infinite configuration network the links between nodes are assigned randomly with the only restriction that the degree distribution has to match a predefined function.

Instanton size distribution in O(3)

open access: yes, 1994
We present calculations of the size distribution of instantons in the 2d O(3) non-linear sigma-model, and briefly discuss the effects cooling has upon the configurations and the topological objects.
