Predictors are employed to estimate the future states of a system that have many engineering applications, e.g. speech signal processors, process controllers, simulators of mechanical movements, etc. Common predictors are based on digital methods and consequently need digital processing equipment. In some cases, e.g. prediction on a real time scale and fast control, digital techniques appear ra...

An accurate model named as the Modified Wolff Model (MWM) is presented as an efficient CAD tool for determination of resonant frequency of the dominant and higher order modes under the multi-layer condition in thin and thick circular microstrip patch antennas. The effects of dielectric cover on the resonant frequency obtained from MWM have been compared against the result of theoretical method ...

This paper presents a theory that encompasses both “plenoptic” (microlens based) and “heterodyning” (mask based) cameras in a single frequency-domain mathematical formalism. Light-field capture has traditionally been analyzed using spatio-angular representation, with the exception of the frequency-domain “heterodyning” work. In this paper we interpret “heterodyning” as a general theory of multi...

Operational Modal Analysis, also known as Output Only Modal Analysis, has in the recent years, been used for determination of modal parameters of civil engineering structures and is now becoming widely used also for mechanical structures. The advantage of the method is that no artificial excitation needs to be applied to the structure, or force signals to be measured. In this paper, the non-par...

MOTIVATION Frequency-domain analysis of biomolecular sequences is hindered by their representation as strings of characters. If numerical values are assigned to each of these characters, then the resulting numerical sequences are readily amenable to digital signal processing. RESULTS We introduce new computational and visual tools for biomolecular sequences analysis. In particular, we provide...

In this paper, an analysis of the tracking performance of several adaptive algorithms is carried out for the case of model structures with xed pole positions. Such structures have recently been proposed as an eecient generalisation of the common FIR model structure. The focus of this work is to analyse the tradeoo between noise sensitivity and tracking ability in the frequency domain by illustr...

In this paper we describe the modification and assessment of a standard multidistance frequency-domain near infrared spectroscopy (NIRS) instrument to perform multifrequency frequency-domain NIRS measurements. The first aim of these modifications was to develop an instrument that enables measurement of small volumes of tissue such as the cervix, which is too small to be measured using a multidi...

In this paper, an analysis of the tracking performance of several adaptive algorithms is carried out for the case of model structures with fixed pole positions. Such structures have recently been proposed as an efficient generalisation of the common FIR model structure. The focus of this work is to analyse the tradeoff between noise sensitivity and tracking ability in the frequency domain by il...
