This paper deals with the robust fault detection(FD) problem in low frequency domain for linear timedelay systems. The H∞ norm and H− index are employed to measure the robustness to unknown inputs and the sensitivity to faults, respectively. The main results include derivation of a sufficient condition for the existence of a robust fault detection observer and a construction of it based on the ...

Nonlinear models are known to provide excellent performance in real-world applications that often operate nonideal conditions. However, such require online processing be performed with limited computational resources. To address this problem, we propose a new class of efficient nonlinear for applications. The proposed algorithms based on linear-in-the-parameters (LIPs) filters using functional ...

among different discretization approaches, finite difference method (fdm) is widely used for acoustic and elastic full-wave form modeling. an inevitable deficit of the technique, however, is its sever requirement to computational resources. a promising solution is parallelization, where the problem is broken into several segments, and the calculations are distributed over different processors. ...

In [1] we presented the language T OY(FD) that integrates the best features of existing functional and logic languages, as well as finite domain (FD) constraint solving. We believe that T OY(FD) is more flexible and expressive than the existing approaches of constraint logic programming on finite domain (CLP (FD) ) as it integrates FD constraint solving, lazy evaluation, higher order applicatio...

Triggered by the release in Feb., 2002 by the Federal Communications Commission of their first authorization for UWB[1], UWB research has been making fast progress across the world. The applications of UWB technology range from multimedia communications, through radar and biomedical image reconstruction, to positioning. Most of the system development for these applications requires the numerica...

Rock-paper-scissors (RPS) dynamics, which maintain genetic polymorphisms over time through negative frequency-dependent (FD) selection, can evolve in short-lived species with no generational overlap, where they produce rapid morph frequency cycles. However, most species have overlapping generations and thus, rapid RPS dynamics are thought to require stronger FD selection, the existence of which...

Given a stream with frequencies fd, for d ∈ [n], we characterize the space necessary for approximating the frequency negative moments Fp = ∑ |fd|, where p < 0 and the sum is taken over all items d ∈ [n] with nonzero frequency, in terms of n, , andm = ∑ |fd|. To accomplish this, we actually prove a much more general result. Given any nonnegative and nonincreasing function g, we characterize the ...

This article presents a method to obtain a myoelectric control system for hand prosthesis with individual fingers, wrist flexion/extension and grasp movements, based on weak surface electromyogram (sEMG) recorded from the forearm, both able-bodied and amputees. This study aims to a reduced-channel scheme (a single sEMG channel) for hand patterns discrimination. A combination of commonly used fe...

Among different discretization approaches, Finite Difference Method (FDM) is widely used for acoustic and elastic full-wave form modeling. An inevitable deficit of the technique, however, is its sever requirement to computational resources. A promising solution is parallelization, where the problem is broken into several segments, and the calculations are distributed over different processors. ...

This paper proposes a spectrum shaping technique exploiting frequency clipping for frequency domain soft canceller with minimum mean square error (FD-SC/MMSE) based turbo equalization systems, of which aims to achieve high spectral efficiency and efficient energy transfer from a transmitter to a receiver, as well as to provide a novel spectrum division multiplexing strategy. In the proposed sch...
