In this research, a nurse call system with simplified initial setting is developed. The constructed by improving an existing driven eye movement, where the movement detected image processing. of previous template images for detection face and were created manually. However, it was not easy operator to generate suitable images. To solve problem, in automatic generation attempted simplify setting...

Abstract—In this paper we extend CSL (Continuous Stochastic Logic) with an expected time and an expected reward operator, both of which are parameterized by a random terminal time. With the help of such operators we can state for example that the expected sojourn time in a set of goal states within some generally distributed delay is at most (at least) some time threshold. In addition, certain ...

Two oppositely charged particles created within a microscopic space-time region can be separated, accelerated over a much larger distance, and brought to a recollision by a laser field. Consequently, new reactions become feasible, where the energy absorbed by the particles is efficiently released. By investigating the laser-dressed polarization operator, we identify a new contribution describin...

We are interested in the differential equations satisfied by the density of the Geometric Stable processes { G α(t); t ≥ 0 } , with stability index α ∈ (0, 2] and symmetry parameter β ∈ [−1, 1], both in the univariate and in the multivariate cases. We resort to their representation as compositions of stable processes with an independent Gamma subordinator. As a preliminary result, we prove that...

We analyse the cosmic-ray signatures of decaying gravitino dark matter in a modelindependent way based on an operator analysis. Thermal leptogenesis and universal boundary conditions at the GUT scale restrict the gravitino mass to be below 600 GeV. Electron and positron fluxes from gravitino decays, together with the standard GALPROP background, cannot explain both, the PAMELA positron fraction...

Let A be a bounded linear operator on a Banach space X. We investigate the conditions of existing rank-one operator B such that I+f(A)B is invertible for every analytic function f on sigma(A). Also we compare the invariant subspaces of f(A)B and B. This work is motivated by an operator method on the Banach space ell^2 for solving some PDEs which is extended to general operator space under some ...

We deal with the boundedness of multilinear fractional integral operator $$I_{\gamma ,m}$$ from a product weighted Lebesgue spaces into adequate Lipschitz spaces. Our results generalize some previous estimates not only for linear case but also unweighted problem in context. characterize classes weights which described above holds and show optimal range parameters involved. The optimality is und...

In this paper, we prove some fixed points properties and demiclosedness principle for a Banach operator in uniformly convex hyperbolic spaces. We further propose an iterative scheme for approximating a fixed point of a Banach operator and establish some strong and $Delta$-convergence theorems for such operator in the frame work of uniformly convex hyperbolic spaces. The results obtained in this...

where 0 < α≤ 1, Γ(α) is the gamma function, {A(t) : t ∈ [0,T]} is a family of linear closed operators defined on dense set D(A) in a Banach space E into E, u is the unknown Evalued function, u0 ∈ D(A), and f is a given E-valued function defined on [0,T]. It is assumed that D(A) is independent of t. Let B(E) denote the Banach space of all linear bounded operators in E endowed with the topology d...
