Given two nonlinear systems which only violate incremental passivity when their gains are sufficiently small, we give a condition for negative feedback interconnection to have finite gain, generalizes the small gain and theorems. The property may be determined graphically by plotting Scaled Relative Graphs (SRGs) of systems, provides engineering significance mathematical result.

In the continuous mills, where strip thickness at entrance contains a high-frequency component caused by eccentricity of rolls previous cage, effectiveness AGC-systems for regulating rolled product depends on speed operation hydraulic roll setting devices (HRSD). Analytical substantiation transfer functions AGC-system and undercut, taking into account real HRSD has been carried out. The frequen...

We conducted two trials to evaluate the effects of extruding vs dry-rolling either corn or grain sorghum on intake, digestibility, and performance of finishing steers. In Trial 1, 92 crossbred steers (average BW 413 kg) were used in a 2 x 2 factorial design. Diets contained either dry-rolled corn (RC), extruded corn (EC), dry-rolled grain sorghum (RGS), or extruded grain sorghum (EGS). Diets we...

Hindgut is a major colonization site for Escherichia coli O157 in cattle. In this study, diets were formulated to effect changes in hindgut fermentation to test our hypothesis that changes in the hindgut ecosystem could have an impact on fecal shedding of E. coli O157. Feedlot heifers (n = 347) were prescreened for the prevalence of E. coli O157 by fecal and rectoanal mucosal swab cultures. A s...

PURPOSE To evaluate efficacy and safety of quarterly (and then monthly) ranibizumab during the 2-year Phase IIIb, multicenter, randomized, double-masked, sham injection-controlled study of the efficacy and safety of ranibizumab in subjects with subfoveal CNV with or without classic CNV secondary to AMD (PIER) study. DESIGN Phase IIIb, multicenter, randomized, double-masked, sham injection-con...

BACKGROUND Testing auditory steady-state responses consists in recording the electrophysiological response to an auditory stimulus. Due to this response, in addition to changes in electric potentials caused by neuron impulses in the auditory path, the sonomotor reflex can also be observed. The sonomotor reflex shows muscle responses to auditory events, and in the case of auditory evoked potenti...

There are many examples of macromolecules that form helical tubes or crystals, which are useful for structure determination by electron microscopy and image processing. Helical crystals can be thought of as two-dimensional crystals that have been rolled into a cylinder such that two lattice points are superimposed. In many real cases, helical crystals of a particular macromolecule derive from a...

In this paper an exhaustive scientific work is performed, by means of metallographic and scanning electron microscope (SEM) techniques, the microstructural defects exhibited pearlitic steels their evolution with manufacturing process cold drawing, analyzing consequences such on isotropic/anisotropic fracture behavior different steels. Thus, objective establishment a relation between damage To e...

Large arrays of multifunctional rolled-up semiconductors can be mass-produced with precisely controlled size and composition, making them of great technological interest for micro- and nano-scale device fabrication. The microtube behavior at different temperatures is a key factor towards further engineering their functionality, as well as for characterizing strain, defects, and temperature-depe...
