The lowpass systems with minimum higher order moments of the impulse response are presented. The optimization of the transfer function parameters is carried out for functions ranging from the second to the tenth order, with zeros at infinity. Besides the system order, no other requirements are set to restrict the frequency domain behavior of the system. Time and frequency domain properties of t...

When fitting a linear regression model to data, the effects not included in the model can confound those included in the model, resulting in incorrect estimates of the regression coefficients and incorrect inferences as to whether a term is significant. This paper shows how uniform designs can reduce this aliasing. The discrepancy is a quantitative measure of how uniformly design points are pla...

We study pathwise predictability of continuous time processes in deterministic setting, when the convolution integrals over future time can be approximated by integrals over past time. Uniform prediction in some weak sense with respect to certain classes of inputs is discussed. We found that all band-limited processes are predictable in this sense, as well as high-frequent processes with zero e...

Using a simple nonlinear filter, it is possible to shift arbitrarily complex wave forms produced by systems with a delayed feedback backwards in time. Physically, this corresponds to a seemingly noncausal transmission of signals. Filter chains allow for signals travelling against the coupling direction of the chain. These apparent paradoxes are resolved, and possible physical implications are d...

Turbidity such as fog, mist, haze, and smoke progressively reduces image contrast and visibility with increasing distance. In this paper, we propose an algorithm to degrade the turbid degree from the turbid image. The turbidity can be considered as a kind of noise. The basic assumption of the proposed algorithm is that an image consists of a reference intensity level and a characteristic intens...

General methods of displacement measurement are to use LVDT, tiltmeter, or laser deflection meter. But these methods can’t be applied effectively if bridge height is so high that the installation of sensor is difficult. So the great part of in these cases, the reliability and accuracy of measured results are uncertain usually. To overcome this problem, in this paper, the two techniques for calc...

This paper presents a novel current control methodology for grid connected doubly-fed induction generator (DFIG) based wind energy conversion systems. Controller is based on a proportional controller with additional first order low pass filter disturbance observer which estimates the parameter dependent nonlinear feed-forward terms. The results in simulations and experimental test bed obviously...

The vulnerability of false data injection attacks on real-time electricity pricing for the power grid market has been recently explored. Previous work has focused on the impact caused by attackers that compromise pricing signals and send false prices to a subset of consumers. In this paper we extend previous work by considering a more powerful and general adversary model, a new analysis method ...

This paper presents a new second order multifunction filter using one active element, requiring only ‘twelve’ CMOS transistors, and four passive elements. The proposed circuit realizes voltage-mode low-pass, high-pass and band-pass functions with the advantages of minimum component count structure, high Q possibility, and high frequency potential. The proposed circuit is verified through PSPICE...
