Treatment process for capillary hemangioma

Background Hemangiomas, usually, present at the first few Hemangiomas, usually, present at the first few months of life and are the most common benign tumor in children. There are various therapeutic methods for hemangioma. Capillary hemangioma is a type of hemangiomas. The steps of treatment of a child with capillary hemangioma in Taleghani Hospital of Gorgan, Iran, are reported. Case re...

Fuzzy Sliding Mode for Spacecraft Formation Control in Eccentric Orbits

The problem of relative motion control for spacecraft formation flying in eccentric orbits is considered in this paper. Due to the presence of nonlinear dynamics and external disturbances, a robust fuzzy sliding mode controller is developed. The slopes of sliding surfaces of the conventional sliding mode controller are tuned according to error states using a fuzzy logic and reach the pre-define...

Quantization of Nilpotent Coadjoint Orbits Quantization of Nilpotent Coadjoint Orbits Quantization of Nilpotent Coadjoint Orbits

Let G be a complex reductive group. We study the problem of associating Dixmier algebras to nilpotent (co)adjoint orbits of G, or, more generally, to orbit data for G. If g = 0 + n + in is a triangular decomposition of g and 0 is a nilpotent orbit, we consider the irreducible components of 0 n n, which are Lagrangian subvarieties of 0. The main idea is to construct, starting with certain "good"...

Orbits, Weak Orbits and Local Capacity of Operators

Let T be an operator on a Banach space X. We give a survey of results concerning orbits {Tnx : n = 0, 1, . . .} and weak orbits {〈Tnx, x∗〉 : n = 0, 1, . . .} of T where x ∈ X and x∗ ∈ X∗. Further we study the local capacity of operators and prove that there is a residual set of points x ∈ X with the property that the local capacity cap(T, x) is equal to the global capacity cap T . This is an an...
