Determining fixed Crane Areas in Rail-Rail Transshipment Yards

Rail-rail transshipment yards are an emerging and more e cient alternative to traditional shunting yards. Instead of a time-consuming reshu ing of railcars via shunting hills, in these modern yards, huge gantry cranes tranship containers between di erent freight trains. As multiple cranes process the trains in parallel, it is an important operational task to avoid interferences among cranes. To...

A non parametric theory for histogram segmentation

Histograms are a widely used tool for data analysis. In this paper, we propose a theory to segment a 1D-histogram without a priori assumptions about the undelying density function. Our approach considers a rigorous definition of an admissible segmentation, which provides a criterion allowing to avoid over and undersegmentation problems. A simple, parameter-free and fast algorithm leading to suc...

Title Theory and design of uniform concentric circular arrays

This paper proposes a new digital beamformer for uniform concentric circular array (UCCA) having nearly frequency invariant (FI) characteristics. The basic principle is to transform the received signals to the phase mode and remove the frequency dependency of the individual phase mode through the use of a digital beamforming network. The far field pattern of the array is determined by a set of ...

Wavelets and the theory of non-parametric function estimation

Non-parametric function estimation aims to estimate or recover or denoise a function of interest, perhaps a signal, spectrum or image, that is observed in noise and possibly indirectly after some transformation, as in deconvolution. ‘Non-parametric’ signifies that no a priori limit is placed on the number of unknown parameters used to model the signal. Such theories of estimation are necessaril...

Wavelet-based non-parametric HMM's: theory and applications

In this paper, we propose a new algorithm for non-parametric estimation of hidden Markov models (HMM's). The algorithm is based on a \wavelet-shrinkage" density estimator for the state-conditional probability density functions of the HMM's. It operates in an iterative fashion, similar to the EM re-estimation formulae used for maximum likelihood estimation of parametric HMM's. We apply the resul...
