The operation of reforming catalysts in a fixed bed reactor undergoes high level interaction between the operating parameters and reaction mechanism. Understanding such an reduces catalyst deactivation rate. In present work, three kinds nanocatalysts (i.e., Pt/HY, Pt-Zn/HY, Pt-Rh/HY) were synthesized. catalysts’ performances evaluated for n-heptane reactions reactor. conditions applied followin...

The height of mechanical mixing layer is one of the parameter of the safety analysis report of any industrial (nuclear) facility due to its relation to the dispersion factor of pollutants. It can provide information about lower atmospheric dispersion, which is usually used to study the pollutants released from nuclear facility, risk analysis and emergency planning. Mixing layer height is diffic...

mulla sadra shirazi by his fundamentals like fundamentality of existence, existential gradation and the unity of being, believes that love equals being and explains how the love moves in all particles in the universe. he maintains that love is divine nature of human existence and it is full of wisdom and expediency sees. although the description of love by the theory of fundamentality of existe...

In this paper, we investigate the existence of a Friedberg numbering in fragments of Peano Arithmetic and initial segments of Gödel’s constructible hierarchy Lα, where α is Σ1 admissible. We prove that (1) Over P− +BΣ2, the existence of a Friedberg numbering is equivalent to IΣ2, and (2) For Lα, there is a Friedberg numbering if and only if the tame Σ2 projectum of α equals the Σ2 cofinality of α.

In this talk we characterize the transonic stationary solutions of the hydrodynamic escape problem (HEP), which is significant on studying the evolution of atmospheres of planets. The characterization is established by the geometric singular perturbation method (GSP) on the wind solution of HEP. We will discuss the existence and non-existence of the adiabatic wind solution with or without heat ...

Non-trivial deformations result in local contractions and expansions. These naturally capture object scalings but can have a negative side effect, namely making object features disappear or inflate. For this reason we want the deformation fields to have zero acceleration in the direction perpendicular to image features; this guarantees that the features are only ‘transported’. This requirement ...

We consider the classical multiple regression model (or linear model). Let Y be a random vector (called response variable) in IR such that IE[Y ] = Xβ and cov(Y ) = σIn where X ∈ Mn,p(IR) is a known matrix (rows of X are the explanatory variables) and where β ∈ IR and σ ∈ IR+ are the unknown parameters (to be estimated). If the rank of X equals to p (which will be assumed here), then the soluti...

A bstract We expand on our results in [1] to present a broad new class of gravitational observables asymptotically Anti-de Sitter space living general codimension-zero regions the bulk spacetime. By taking distinct limits, these can reduce well-studied holographic complexity proposals, e.g., volume maximal slice and action or spacetime Wheeler-DeWitt patch. As with codimension-one family found ...
