In this note, a generalization of higher rank numerical range isintroduced and some of its properties are investigated

Background:Body packers occasionally refer to the Emergency Department (ED), after leakage of package contents within intestinal lumen, resulting in life-threatening toxicities, depending upon the nature of the chemical product. Case Presentation: We present a case report of a patient presented with sudden onset of drowsiness while he was on board a flight. He was brought in by the airport secu...

In this paper, we de ne the concepts of general fuzzy recognizer, language recognized by a general fuzzy recognizer, the accessible and the coac- cessible parts of a general fuzzy recognizer and the reversal of a general fuzzy recognizer. Then we obtain the relationships between them and construct a topology and some hypergroups on a general fuzzy recognizer.

Random Hermitian matrices are used to model complex systems without time-reversal invariance. Adding an external source to the model can have the effect of shifting some of the matrix eigenvalues, which corresponds to shifting some of the energy levels of the physical system. We consider the case when the n× n external source matrix has two distinct real eigenvalues: a with multiplicity r and z...

Data envelopment analysis (DEA) is proposed in this paper to generate local weights of alternatives from pair-wise comparison judgment matrices used in the analytic hierarchy process (AHP). The underlying assumption behind the approach is explained, and some salient features are explored. It is proved that DEA correctly estimates the true weights when applied to a consistent matrix formed using...

introduction: the prevalence of somatic chromosomal abnormalities in infertile male individuals has been reported to vary in different literatures. the aim of this study was to investigate the frequency of chromosomal aberrations among infertile men referred to the cytogenetic laboratory of iran blood transfusion organization research centre (ibto). materials and methods: chromosomal analysis w...

camptomelic dysplasia (cmd) is a rare autosomal dominant congenital dwarfism characterized by shortness and bowing of long bones (camptomelia) and other severe skeletal and extra skeletal malformations. cmd is generally considered to be lethal and the majority of cases die in the neonatal period due to respiratory insufficiency. we hereunder report a term male neonate with characteristic clinic...

A large number of multi-criteria methods have been developed to deal with different kinds of problems. Most of them use a linear aggregation, what is the cause of many shortcomings in solving decision problems. This paper presents how to identify nonlinear multi-criteria decision-making models with using the new fuzzy method: the Characteristic Objects Method (COMET). In this approach, models a...

Recently, some researches have been carried out in the context of using data envelopment analysis (DEA) models to generate local weights of alternatives from pairwise comparison matrices used in the analytic hierarchy process (AHP). One of these models is the DEAHP. The main drawback of the DEAHP is that it generates counter-intuitive priority vectors for inconsistent pairwise comparison matric...
