As a non-parametric technique, Data Envelopment Analysis (DEA) evaluates the relative efficiency of peer decision making units (DMUs) that have multiple inputs and outputs. In many situations, DMUs have a two-stage structure, where * Corresponding author. E-mail address: [email protected] (A. Ashrafi) 1436 A. Ashrafi, A. B. Jaafar, L. S. Lee and M. R.

Super-resolution image reconstruction algorithms produce a high-resolution image from one or a set of low-resolution images of the desired scene. In this paper, we present a novel two-stage super-resolution (SR) algorithm combined sparse signal representation with the projection onto convex sets (POCS). In the first stage, inspired by recent results in sparse signal representation, we get a hig...

Background. Many statistical models have been tested to predict phenotypic or virological response from genotypic data. A statistical framework called Super Learner has been introduced either to compare different methods/learners (discrete Super Learner) or to combine them in a Super Learner prediction method. Methods. The Jaguar trial is used to apply the Super Learner framework. The Jaguar st...

We discuss super Schrödinger algebras with less supercharges from N=4 superconformal algebra psu(2,2|4). Firstly N=2 and N=1 superconformal algebras are constructed from the psu(2,2|4) via projection operators. Then a super Schrödinger subalgebra is found from each of them. The one obtained from N=2 has 12 supercharges with su(2)2×u(1) and the other from N=1 has 6 supercharges with u(1) . By co...

chronic liver diseases in children is the result of many different diseases including: metabolic, genetic, infectious, toxic and idiopathic causes. this was a case series study on 133 infants and children with age range 6 month to 12 years old, who presented clinically with manifestation of chronic liver disease and were admitted to children hospital medical center from year 1999 to 2000. in th...
