3-D models and structural analysis of rock avalanches: the study of the deformation process to better understand the propagation mechanism [PDF]
Rock avalanches are extremely destructive and uncontrollable events that involve a great volume of material (> 106 m3) and several complex processes, and they are difficult to witness. For this reason the study of these phenomena using analog modeling

An Electrically Programmable Split-Electrode Charge-Coupled Transversal Filter (EPSEF) [PDF]
A CCD split-electrode transversal filter (EPSEF) with analog controlled tap weights is described. The programmable tap weighting utilizes a novel analog multiplier for sampled data, based on charge profiling underneath a resistive gate structure.

Cascade Structure for Finite Impulse Response Filters and Linear Prediction
This paper presents a complete analysis of the cascade structure for adaptive transversal filters based on adaptive algorithms. The standard structure of the cascade transversal FIR filter is obtained by replacing the whole structure by small ones with ...

Nonlinear Performance on Acoustic Transversal Filters
The recently proposed transversal topology for creating acoustic filters allows to achieve arbitrary filter responses, in terms of position of transmission zeros and bandwidth, among others. This new topology might indeed help to give response to the demanding filter specification of the recent and future wireless communication systems, some not yet ...

Low-complexity RLS algorithms using dichotomous coordinate descent iterations [PDF]
In this paper, we derive low-complexity recursive least squares (RLS) adaptive filtering algorithms. We express the RLS problem in terms of auxiliary normal equations with respect to increments of the filter weights and apply this approach to the ...

Optoelectronic transversal filter
The development of a 1 GHz bandwidth, 15 tap transversal filter with optical fibre delays and controllable bipolar weights set with variable sensitivity GaAs metal–semiconductor–metal photodetectors is reported. The performance of the filter is demonstrated by configuring it as tunable bandpass filter.
