Link adaptation in LTE-A is based on channel state information (CSI). For time-selective channels, CSI might be outdated already in the next subframe. Hence, CSI prediction must be employed. This paper investigates support vector regression (SVR) for channel extrapolation and prediction. SVR is applied for learning from the previous channel estimates in order to predict the CSI of the following...

Several models have been proposed to analyse dose-response curves recorded in bronchoprovocation challenge tests. The aims of the present work were: 1) to investigate which model (linear vs exponential) and which minimization method (trials and errors vs Levenberg-Marquardt) gives better results in terms of data interpolation (goodness-of-fit); and 2) to verify the validity of extrapolation by ...

In this paper, we deal with the semilinear wave equation with strong damping. By choosing a suitable state space, we characterize the interpolation and extrapolation spaces of the operator matrix Aθ, analysis the criticality of the ε-regular nonlinearity with critical growth. Finally, we investigate the global existence of the ε-regular solutions which have bounded X ×X norms on their existence...

This paper introduces a modification to genetic algorithms which provides computational support to creative designing by adaptively exploring design structure spaces. This modification is based on the re-interpretation of the GA's crossover as a random sampling of interpolations and its replacement with the random sampling of direct phenotype-phenotype interpolation and phenotypephenotype extra...

In this paper, we will prove a discrete Rubio De Francia extrapolation theorem in the theory of Ap? Muckenhoupt weights for which Hardy-Littlewood maximal operator is bounded on ?p w (Z+). The results be proved by employing self-improving property and Marcinkiewicz Interpolation Theorem.

We consider the variable coefficient Poisson equation with Dirichlet boundary conditions on irregular domains. We present numerical evidence for the accuracy of the solution and its gradients for different treatments at the interface using the Ghost Fluid Method for Poisson problems of Gibou et al. (J. Comput. Phys. 176:205–227, 2002; 202:577–601, 2005). This paper is therefore intended as a gu...

The extended abstract describes a distributed visualization system called Spiegel, which displays and analyzes the results of N body simulations of dense stellar systems. The visualization system allows exploring the simulation by moving through time and space. The extended abstract also discusses interpolation/extrapolation techniques, and data reduction methods, which are used.

We propose a preprocessing technique which allows stable interpolation and error correction. It can be regarded as a parallel concatenated (real) code with an interleaver. We discuss the relative performance and stability of the technique, when compared to the single-channel case (bandlimited interpolation, extrapolation, and error-correction). We give examples that show that the condition numb...
