We describe filtering by short‐period multiples in one dimension using a combination of the O’Doherty‐Anstey (1971) formula with a stochastic model in which the autocorrelation of acoustic impedance decreases exponentially with lag [Formula: see text] while the spectrum of reflection coefficients rises with frequency up to a corner, then is approximately constant, [Formula: see text] An impedance log with these statistics is a generalization of the classic random telegraph wave. The parameter [Formula: see text], the mean‐square fractional fluctuation of impedance, is typically less than 1 per

Résumé :
ABSTRACT Trend filtering – first introduced into the astronomical literature in Paper I of this series – is a state-of-the-art statistical tool for denoising 1D signals that possess varying degrees of smoothness. In this work, we demonstrate the broad utility of trend filtering to observational astronomy by discussing how it can contribute to a variety of spectroscopic and time-domain studies. The observations we discuss are (1) the Lyman-α (Lyα) forest of quasar spectra; (2) more general spectroscopy of quasars, galaxies, and stars; (3) stellar light curves with planetary transits; (4) eclips

Résumé :
In this research, a high-performance IIR filter for low-power DSP applications is implemented and realized using a MATLAB system generator. There are numerous ways to implement IIR filters, including the Direct Form-I(DF-I), Direct Form-II(DF-II), Cascade, and Parallel Forms. All of these structures offer a selection area for a suitable realization that will decrease power consumption and increase the speed of digital filters. This particular work uses a Xilinx FPGA device to implement a 5th order Low pass IIR filter in DF-I, DF-II, and Cascade Form (DF-I/DF-II). Cascade (Direct Form-I) realiz

Résumé :
During last years, the combination of several filtering techniques for the development of anti-spam systems has gained a enormous popularity. However, although the accuracy achieved by these models has increased considerably, its use has entailed the emergence of new challenges such as the need to reduce the excessive use of computational resources, the increase of filtering speed and the adjustment of the weights used for the combination of several filtering techniques. In order to achieve this goal we have been refined several aspects including: (i) the design and development of small techni

Résumé :
This work proposes a simple filtering approach that can be applied to digital surface models in order to extract digital terrain models. The method focusses on robustness and computational efficiency and is in particular tailored to filter DSMs that are extracted from satellite stereo images. It represents an evolution of an existing DTM generation method and includes distinct advancement through the integration of multi-directional processing as well as slope dependent filtering, thus denoted “MSD filtering”. The DTM generation workflow is fully automatic and requires no user interaction. Exe

Internet has dramatically changed the ways of communication and access to information. The large amount of information available on the web and the lack of filters for publication imply that people face great difficulties in accessing to high quality information. Deficiencies of Internet search engines and the lack of information literacy bring more restrictions to achieve an efficient access to valuable web resources. To address these problems and provide their users with high quality web resources, libraries have designed and implemented different solutions. Subject gateways are probably the

Motion detection, velocity filtering and the detection of change in a given scene are all important aspects for optical processing architectures and systems.

The electronic techniques however may have only limited applications due to the sequential nature of the process.
