Assimilating real time sensor into a running simulation model can improve simulation results for simulating large-scale spatial temporal systems such as wildfire, road traffic and flood. Particle filters are important methods to support data assimilation. While particle filters can work effectively with sophisticated simulation models, they have high computation cost due to the large number of ...

Switching power converters are widely used due to their excellent efficiency, but they inherently generate ripple. Passive low-pass LC filters have been traditionally employed to meet ripple and EMI specifications [1]. These passive filters can contribute considerably to the volume and weight of a power converter. In particular, capacitors can become relatively large in order to meet strict rip...

This paper presents design algorithms for hybrid filter banks (HFB’s) for high-speed, high-resolution conversion between analog and digital signals. The HFB is an unconventional class of filter bank that employs both analog and digital filters. When used in conjunction with an array of slower speed converters, the HFB improves the speed and resolution of the conversion compared with the standar...

We develop a theory of stratified $LM$-filters which generalizes the theory of stratified $L$-filters. Our stratification condition explicitly depends on a suitable mapping between the lattices $L$ and $M$. If $L$ and $M$ are identical and the mapping is the identity mapping, then we obtain the theory of stratified $L$-filters. Based on the stratified $LM$-filters, a general theory of lattice-v...

Abstract The simulation of complex deformation problems often requires enrichment techniques that introduce local high‐resolution detail on a generally coarse discretization. use cases include spatial or temporal refinement the discretization, composite materials with phenomena occurring at different scales, even codimensional simulation. We present an efficient method for both discretization a...

This paper discusses monitoring within wired and wireless networks and the type of monitoring information needed to support different applications. We suggest a hybrid active/passive monitoring approach with a dynamic time window mechanism and interchangeable filters to extract requested information. The paper also shows our initial experimental results and presents our conclusions. Keywords-Ne...

This paper presents an approach to accurate and scalable multiple-model state estimation for hybrid systems with intermittent, multi-modal dynamics. The approach consists of using discrete-state estimation to identify a system’s behavioral context and determine which motion models appropriately represent current dynamics, and which multiple-model filters are appropriate for state estimation. Th...

A new operator to compute time differentiation in an image sequence is presented. It is founded on hybrid filters combining morphological and linear recursive operations. It estimates recursively the amplitude of time-variation within a certain interval. It combines the change detection capability of the temporal morphological gradient, and the (exponential) smoothing effect of the linear recur...

This paper reports different strategies for electrical dispersion compensation of optical single sideband transmission systems. We investigate and compare the mitigation of the chromatic dispersion impairment using dispersive microstrip lines, Butterworth filters, and hybrid schemes employing an adaptive filter. Simulation results are presented at 10 Gbit/s, proving transmission over 600km of d...
