Data Envelopment Analysis (DEA) is one of the best methods for measuring the efficiency and productivity of Decision Making Units (DMU). Evaluating the efficiency of DMUs which have two or several stages by using the conventional DEA models, is equal to consider them as black box. This method, omits the effect of intermediate measure on efficiency. Therefore, just the first network inputs and t...

this paper deals with aerodynamic design of fan and compressor assembly for turbofan engines having arbitrary by-pass ratios. two different softwares were developed in this respect. first, based on general performance data at design point condition, a one-dimensional approach was activated. initial flow passages of both fan and compressor, together with splitter position were developed utilizin...

Halliday’s Systemic Functional Linguistics (SFL) has stood the test of time as a model of text analysis. The present literature contains a plethora of studies that while taking the ‘clause’ as a unit of analysis have put into investigation the metafunctions in research articles of a single field of study or those of various fields in comparison. Although ‘clause complex’ is another unit of SF a...

Projection clustering is an important cluster problem. Although there are extensive studies with proposed algorithms and applications, one of the basic computing architectures is that they are all at the level of data objects. The purpose of this paper is to propose a new clustering technique based on grid architecture. Our new technique integrates minimum spanning tree and grid clustering toge...

The Einasto profile has been successful in describing the density profiles of dark matter haloes $\Lambda$CDM N-body simulations. It also able to describe multiple components surface brightness galaxies. However, analytically projecting it calculate quantities under projection is challenging. In this paper, we will see development a highly accurate analytical approximation for mass (or counts) ...

In this paper, a new smoothed particle hydrodynamics (SPH) algorithm for simulation of elastic-plastic deformation of solids was proposed. The key point was that materials under highvelocity impact (HVI) behave like fluids. This led to propose a method which was similar to the socalled SPH-projection method, in which the momentum equations are solved as the governing equations. The method consi...

Abstract The timing of Quaternary uplift evolution the Simbruini range (Central Apennines, Italy) is poorly known due to lack reliable chronological constraints post‐orogenic continental clastic units, deposited after upper Messinian thrust‐top facies, and tectonic events. In this regard, we identified main geomorphic markers, including several levels whose plano‐altimetric projection along riv...

Suppose $pi:mathcal{A}rightarrow mathcal{B}$ is a surjective unital $ast$-homomorphism between C*-algebras $mathcal{A}$ and $mathcal{B}$, and $0leq aleq1$ with $ain  mathcal{A}$. We give a sufficient condition that ensures there is a proection $pin mathcal{A}$ such that $pi left( pright) =pi left( aright) $. An easy consequence is a result of [L. G. Brown and G. k. Pedersen, C*-algebras of real...

We study the one-dimensional asymmetric simple exclusion process on lattice $\{1, \dots,N\}$ with creation/annihilation at boundaries. The boundary rates are time dependent and change a slow scale $N^{-a}$ $a>0$. prove that $N^{1+a}$ system evolves quasi-statically macroscopic density profile given by entropy solution of stationary Burgers equation densities changing in time, determined corresp...
