Let H be an infinite--dimensional Hilbert space and K(H) be the set of all compact operators on H. We will adopt spectral theorem for compact self-adjoint operators, to investigate of higher derivation and higher Jordan derivation on K(H) associated with the following cauchy-Jencen type functional equation 2f(frac{T+S}{2}+R)=f(T)+f(S)+2f(R) for all T,S,Rin K(H).

We will adopt spectral theorem for compact self-adjoint operators, to investigate ofhigher derivation and higher Jordan derivation on K(H) associated with the following Cauchy-Jensentype functional equation 2f((T + S)/2+ R) = f(T ) + f(S) + 2f(R) for all T, S, R are in K(...

turbocharging an engine boosts its power by increasing the amount of input air. this task is accomplished by using the exhaust gas to power a turbine which is engaged with a compressor. the variable geometry turbocharger, vgt is a unique turbocharger that the diffuser vane angle can be changed over a wide range of positions. the mathematics of turbomachinery flow analysis is intensive and uses ...

this article studies five major classical hollywood films: psycho, casablanca, double indemnity, the apartment and the searchers and ratiocinates that in this era of cinema history, directors conform with a series of principles, procedures and protocols in order to start the films and also describes that these principles are based on philosophical theories of human minds ways of reasoning. this...

The apparent shear viscosity of p-methoxybenzylidene-p'-n-butylaniline in the presence of electrohydrodynamic convection (EHC) is investigated experimentally. In the absence of an electric field, directors are almost aligned along the flow direction such that the viscosity is close to the minimum of the Miesowicz viscosities. Since EHC disturbs the flow-aligned director configuration, the visco...

In the present investigation, the magnetohydrodynamic Falkner-Skan flow of tangent hyperbolic nanofluids over a stretching/shrinking wedge with variable suction, internal heat generation/absorption and chemical reaction with activation energy have been scrutinized. Nanofluid model is composed of “Brownian motion’’ and “Thermophoresis’’. Transformed non-dimensional coupled non-linear equations a...

PURPOSE The purpose of this paper is to explore the various ways in which clinical executive directors and non-clinical executive directors are interpreting and responding to the extensive reforms and restructuring in the UK health service. DESIGN/METHODOLOGY/APPROACH The paper draws upon detailed research in two very large teaching hospital organizations in order to understand how actors cru...

Résumé. L'objectif de ce papier est de présenter une contribution à la modélisation des individus et de leurs relations pour permettre l’aide à l'intégration des acteurs dans une organisation. Nous étudions en particulier le cas du remplacement d'un acteur (« turn-over »). Dans ce cadre, nous proposons un modèle regroupant un ensemble de données relatives à un individu, aux relations que celui-...

‎It is a well-known fact that finding a minimum dominating set and consequently the domination number of a general graph is an NP-complete problem‎. ‎In this paper‎, ‎we first model it as a nonlinear binary optimization problem and then extract two closely related semidefinite relaxations‎. ‎For each of these relaxations‎, ‎different rounding algorithm is exp...
