W. Zhou and J. Kou present a third-order variant of Potra-Pták’s iterative method for solving nonlinear systems in Banach spaces, by using a new vector extrapolation technique, whose local...

If A is an nxn complex matrix and λ is an eigenvalue of A with geometric multiplicity k, then λ is in at least k of the Geršgorin discs Di of A. Let k, r, t be positive integers with k ≤ r ≤ t . Then there is a t x t complex matrix A and an eigenvalue λ of A such that λ has geometric multiplicity k and algebraic multiplicity t, and λ is in precisely r Geršgorin Discs of A. Some examples and rel...

This paper is devoted to the localization of magnetoacoustic sources moving in a straight line at a constant speed. Our technique is based on the association of narrow band acoustic signals and magnetostatic measurements. First of all, we describe features that make possible the association of magnetic and acoustic data, secondly, we show that positioning accuracy is much improved by this assoc...

The geometric entropy arising from partitioning space in a fluid " field theory " is shown to be linearly proportional to the area of an excluded region. The coefficient of proportionality is related to surface tension by a thermodynamic argument. Good agreement with experimental data is obtained for a number of fluids. The calculation employs a density matrix formalism developed previously for...

The discovery of the self similarity of Ethernet traac at Bellcore has had a profound eeect on the world of performance modelling. This paper examines the eeects of self similarity of input traac on the performance of a queue. We use a traac characterisation due to Robert and Le Boudec which allows self similar traac with an arbitrary mean and Hurst parameter to be generated. The technique give...

Linear transformation, such as rotation, scaling, or any combinations of geometric attacks, is among the most common forms of image manipulation. This letter proposes a forensic technique that estimates the linear transformation of an investigated image. We exploited the periodic properties of interpolation by the second-derivative of the transformed image in both the row and column directions....

We describe a GPUand multicore-oriented implementation technique for a key component of finite element based simulation toolkits for partial differential equations on unstructured grids: Geometric Multigrid solvers. We use efficient sparse matrix-vector multiplications throughout the solver pipeline: within the coarse-grid solver, smoothers and even grid transfers. Our implementation can handle...

I n this paper, we present a novel algorithmic approach, the hybrid matrix geometric/invariant subspace method, f o r finding the stationary probability distribut ion of the f inite QBD process which arises in performance analysis of computer and communication systems. Assuming that the QBD state space i s defined in two dimensions with m phases and K f 1 levels, the solution Vector for level k...
