In this paper we study approximation schemes for a nonlinear filtering problem of a partially observed diffusive system when the state process X is the solution of a stochastic delay diffusion equation with a constant time lag τ and the observation process is a noisy function of the state. The approximating state is the linear interpolation of a modified Milstein scheme, which is asymptotically...

The linear-phase IIR filters are described in many cases, mainly due to distortion-free transmission of signals. One of the major problems of IIR filter design is stability, which can be obtained with suitable value of group delay τ . This paper concerns calculation of filter order N and group delay τ in case of quasi-equiripple design of IIR filters. We propose a novel procedure for determinin...

Transistor designs based on using mixed Γ-L valleys for electron transport are proposed to overcome the DOS bottleneck while maintaining high injection velocities. Using a self consistent top-of-the-barrier transport model, improved current density over Si is demonstrated in GaAs/AlAsSb, GaSb/AlAsSb and Ge-on-insulator (Ge-OI) based single-gate (SG) thin-body n-channel metal-oxide-semiconductor...

INTRODUCTION AND VARIABLE DEFINITION: Many upper-limb, multifunctional prosthesis controllers analyze fixed segments of EMG data collected from the residual musculature in an attempt to discern the intended movement of the user. However, many researchers have designed controllers with little or no regard for the delay the controller will introduce when operated in real-time. If the delay is too...

This paper presents a speech enhancement method to suppress the car noise interference. A linear microphone array is adopted for far-talking speech acquisition and delayand-sum beamforming noise reduction. We exploit an effective time delay estimator using the coherence function between the reference microphone and the beamformed speech. To further enhance the beamformed speech, we design an im...

Semiconductor nanowires are potential alternatives to conventional planar (MOSFETs). Nanowire FETs (NWFETs) have a unique electronic structure which we can try and exploit. Carriers in nanowires have longer mean free paths and are subjected to reduced scattering thanks to onedimensional quantum confinement effects. Unlike carbon-nanotubes (CNTs), the electronic properties of nanowires are highl...

Under the hypothesis that prey x t has a gestation in 1.1 , we modify it to be the following one: dx t dt xg x − yp x − τ , dy t dt y −h ep x ] − zqy, dz t dt z −s mqy, 1.3 where τ is the time of gestation. The purpose of current work is to analyze the effect of delay on the dyna...

Some analytical results concerning PI controller tuning based on integrator plus time delay models are worked out and presented. A method for obtaining PI controller parameters, Kp = α kτ , and, Ti = βτ , which ensures a given prescribed maximum time delay error, dτmax, to time delay, τ , ratio parameter δ = dτmax τ , is presented. The corner stone in this method, is a method product parameter,...
