The aim of this note is rst to set up some general theory for discussing diierent aspects of the notion of a logic and then to draw attention to the schematic aspects of logic and suggest a way of capturing this aspect without making any commitment to the kind of syntax a logic should have.

Abstract The use of the mercury intrusion method has been one most relevant trends in determining permeability porous media past decades. In this paper, general knowledge sandstone reservoir evaluation is delineated including pore distribution sandstones and air measurement. Based upon paradigmatic study conducted by Purcell, a schematic diagram illustrating apparatus used shown introduced, pro...

The field-induced transition in one-dimensional S = 1 Heisenberg antiferromagnet with single-ion anisotropy in the presence of a transverse magnetic field is obtained on the basis of the Schwinger boson mean-field theory. The behaviors of the specific heat and susceptibility as functions of temperature as well as the applied transverse field are explored, which are found to be different from th...

This paper evaluated an integrated water resources management approach through linked WEAP-MODFLOW model. Study area is Ravasnar-Sanjabi plain located in Kermanshah province in the west of Iran. A MODFLOW model was evaluated and then, accepted as a groundwater model for the region in present research. Schematic WEAP model was provided as representing general features of water resources system a...

Molecular graphics provides an intuitive way for representation, modeling and analysis of complex chemical and biological systems. It is now widely used in the theoretical chemistry, structural biology, molecular modeling and drug design communities. Traditional molecular graphics techniques mainly dedicate to showing molecular architectures at three-dimensional (3D) level. However, in some occ...

Abstract We consider a chemical freeze-out mechanism which is based on a strong medium dependence of the rates for inelastic flavor-equilibrating collisions based on the delocalization of hadronic wave functions and growing hadronic radii when approaching the chiral restoration. We investigate the role of mesonic (pion) and baryonic (nucleon) fluctuations for melting the chiral condensate in th...

The Angular Radial Edge Histogram (AREH) extends prior work on a compact image representation based on geometric distributions of edge pixels. Histograms of edge pixels are computed along the dimensions of angle and radius. Fourier transform is applied to accommodate rotation invariance. It achieves invariance for scale variation, in-plane rotation, and translation. By using a grid-based approa...

The 18-level primitive equation, general circulation model described in Part I was used to study the diffusion of two idealized tracers in the stratosphere. One traccr was designed to simulate broadly the behavior of the radioactive tungsten which escaped lnto the stratosphere following nuclear tests in the Tropics, the other was taken as a photochemical ozone distribution. Both the meridional ...

In Quarterly Progress Report No. 56 (pages 104-107) some preliminary measurements performed on an elementary X-line were presented. Detailed measurements have been made on several variations of this structure to ascertain the factors that determine the edges of the lowest passband. The X-lines that were tested were made from obstacles like that shown in Fig. VI-1, separated by hollow cylindrica...
