in this thesis,spin dependend transport and electron transport through of ng/sg(graphene/ superconductor graphen) are studied in the junction of ng/fgt/sg. due to andreev reflection conductance increases in the presence of superconductor graphene.also, by applying a voltage gate on a superconductor, fermi level shifts and the conductance is independent of ferromagnatic substrate. also, the cond...
since direct experimental evidence is not available, this must be verified through a modeling approach, providedadequate data be available. many statistical methods are used to study the relation between independent anddependent variables.this research was carried out at the western part of jazmurian basin tlocated in the southeast ofiran. in this paperused ten physical characteristics such as ...
in the first chapter we study the necessary background of structure of commutators of operators and show what the commutator of two operators on a separable hilbert space looks like. in the second chapter we study basic property of jb and jb-algebras, jc and jc-algebras. the purpose of this chapter is to describe derivations of reversible jc-algebras in term of derivations of b (h) which are we...
In the ECOOP’97 conference, the author of the present paper investigated a conservative extension, called Ob+1<:, of the first-order Object Calculus Ob1<: of Abadi and Cardelli, supporting method extension in presence of object subsumption. In this paper, we extend that work with explicit variance annotations and selftypes. The resulting calculus, called Ob+s<:, is a proper extension of Ob+1<:....
wireless sensor networks (wsns) are one of the most interesting consequences of innovations in different areas of technology including wireless and mobile communications, networking, and sensor design. these networks are considered as a class of wireless networks which are constructed by a set of sensors. a large number of applications have been proposed for wsns. besides having numerous applic...

Background The migration of dentists is a major policy challenge facing both developing and developed countries. Dentists from over 120 countries migrate to Australia, and a large proportion are from developing countries. The aim of the study was to assess the life story experience (LSE) of migrant dentists in Australia, in order to address key policy challenges facing dentist migration. Meth...
power transformers are important equipments in power systems. thus there is a large number of researches devoted of power transformers. however, there is still a demand for future investigations, especially in the field of diagnosis of transformer failures. in order to fulfill the demand, the first part reports a study case in which four main types of failures on the active part are investigate...
