It is demonstrated that in a two-stage scenario with elementary Poissonian emitters of particles (colour strings) arbitrarily distributed in their number and average multiplicities, the forward-backward correlations are completely determined by the final distribution of forward particles. The observed linear form of the correlations then necessarily requires this distribution to have a negative...

In this note, we study the non-linear evolution problem dYt = −AYtdt +B(Yt)dXt, whereX is a γ-Hölder continuous function of the time parameter, with values in a distribution space, and −A the generator of an analytical semigroup. Then, we will give some sharp conditions on X in order to solve the above equation in a function space, first in the linear case (for any value of γ in (0, 1)), and th...

non-fragile observer design is the main problem of this paper. using continuous frequency distribution, the stability conditions based on integer order lyapunov theorem are derived for lipschitz class of nonlinear fractional order systems. the proposed observer is stable beside the existence of both gain perturbation and input disturbance. for the first time, in this paper a systematic method i...

in restructured power systems and in a wholesale power market, a distribution company as a market player intends to maximize its profit by utilizing its options. hence determining an optimal energy acquisition strategy for a distribution company is vital, for attaining to this goal. however an important challenge for determining these strategies is forecasting other competitors and generation c...

We prove that if t 7→ u(t) ∈ BV(R) is the entropy solution to a N × N strictly hyperbolic system of conservation laws with genuinely nonlinear characteristic fields ut + f(u)x = 0, then up to a countable set of times {tn}n∈N the function u(t) is in SBV, i.e. its distributional derivative ux is a measure with no Cantorian part. The proof is based on the decomposition of ux(t) into waves belongin...

Nonlinear behavior of a functionally graded cantilever beam is analyzed under non-uniform hygro-thermal effect. To solve this problem, finite element method is applied within plane solid continua. Total Lagrangian approach is utilized in the nonlinear kinematic relations. Newton-Raphson method with incremental displacement is used in nonlinear solution. Comparison study is performed. Effects of...

In this paper, static response and buckling analysis of functionally graded saturated porous beam resting on Winkler elastic foundation is investigated. The beam is modeled using higher-order shear deformation theory in conjunction with Biot constitutive law which has not been surveyed so far. Three different patterns are considered for porosity distribution along the thickness of the beam: 1) ...
