Figure 7. Numerical demonstration of utility of SI for gauging similarity between time series. Top: noisy phase-modulated sine waves with a common carrier frequency and common initial phase. Starting at the 250-second mark, a 500-point segment of one was substituted with a 90° phase-shifted copy of the other. Bottom: numerically computed SI at the carrier frequency.

The role of the Salmonella typhimurium fimbrial operons, lpf, fim, and pef, in adhesion to and invasion of epithelial cell lines was investigated. An S. typhimurium lpfC mutant was unable to adhere to or to invade HEp-2 cells, while an S. typhimurium fim deletion mutant did not attach to or enter HeLa cells. These results suggest that adhesion is a prerequisite for invasion and that distinct fi...

This paper presents an efficient technique for enhancement of IR images, its basic idea is to use nonlinearities applied on the main trend in images extracted through a LPF and details HPF. Magnification applied, while damping or local mean also accomplished attenuate darkness effect IRimages. Anon-linear model anther gain factor .this derived from image proposed approach succeeded quality

A compact ultra-wideband (UWB) bandpass filter (BPF) with wide passband using defected ground structure (DGS) is proposed. The proposed UWB filter is constructed by cascading a high pass filter (HPF) and a lowpass filter (LPF). HPF with short-circuited stubs is used to realize the lower stopband and a LPF is used to attenuate the upper stopband. In order to make the filter size compact, DGS tec...

The roles of flagella and five fimbriae (SEF14, SEF17, SEF21, pef, lpf) in the early stages (up to 3 days) of Salmonella enterica serovar Enteritidis (S. Enteritidis) infection have been investigated in the rat. Wild-type strains LA5 and S1400 (fim+/fla+) and insertionally inactivated mutants unable to express the five fimbriae (fim-/fla+), flagella (fim+/fla-) or fimbriae and flagella (fim-/fl...

In grid-connected converter control, grid voltage feedforward is usually introduced to suppress the influence of the grid voltage distortion on the converter’s grid-side AC current. However, Owing to the time-delay in the control system, the suppression effect of grid voltage distortion is seriously affected. In this paper, the positive effects of the grid voltage feedforward control are analyz...

The concept of a longest previous factor (LPF) is inherent to Ziv-Lempel factorization of strings in text compression, as well as in statistics of repetitions and symmetries. It is expressed in the form of a table --LPF[i] is the maximum length of a factor starting at position i, that also appears earlier in the given text. We show how to compute efficiently three new tables storing different v...

To encode the speech quality with reduce the redundancy within samples that resulted from domain processing method like PCM and LPC, Source coding or Waveform coding methods can be considered. However, it is well known that when conventional sampling methods are applied directly to speech signal, the required amount of data is comparable to or more than that of uniform sampling method. To overc...
