We present a novel technique to accurately map the complete field-of-coverage of a camera to its pan-tilt space in an efficient manner. This camera model enables mapping the coordinates of any (x, y) point in the camera’s current image to that point’s corresponding orientation in the camera’s pan-tilt space. The model is based on the elliptical locus of the projections of a fixed point on the o...

In this paper block diagram representation of optical feedback between two resonator mirrors suffering a phase shift in each round trip during propagation depending on the separation is studied and transfer function model of the loss less Fabry-parot cavity(EFPI) is developed in S-domain. An extrinsic Fabry-Perot interferometer with perfectly parallel surface between the cavity shows efficient ...

Open-loop linear parametric models were exploited to describe ventricular repolarization duration (VRD) variability during graded head-up tilt. Surface ECG and thoracic movements were recorded in 15 healthy humans (age: 24-54 yr, median: 28 yr; 6 women and 9 men). Tilt table inclinations ranged from 15 to 90 degrees and were varied in steps of 15 degrees . All subjects underwent recordings at e...

The disclination-structural units model ~DSUM!, which was previously applied to grain boundaries in metals and a limited number of structures in the diamond cubic lattice, is extended to treat more complicated metastable structures of ^001& and ^011& symmetric tilt boundaries in diamond. These structures are described in terms of flat and faceted disclination dipole walls and screw dislocation ...

This study aims at investigating the interface between emotion and intonation patterns (more specifically, duration and pitch amplitude of speech). To this end, the acoustic properties of spectral parameters related to speech prosody are investigated. The results of acoustic and Statistical analysis show that mean level and range of FO in the contours vary strongly as a function of the degree o...

A lumped parameter model of the cardiovascular system has been developed and optimized using experimental data obtained from 13 healthy subjects during graded head-up tilt (HUT) from the supine position to [Formula: see text]. The model includes descriptions of the left and right heart, direct ventricular interaction through the septum and pericardium, the systemic and pulmonary circulations, n...

The x-ray coordinates of beta-barrel transmembrane proteins from the porins superfamily and relatives are used to calculate the mean tilt of the beta-strands and their mean local twist and coiling angles. The 13 proteins examined correspond to beta-barrels with 8 to 22 strands, and shear numbers ranging from 8 to 24. The results are compared with predictions from the model of Murzin, Lesk, and ...

When biological macromolecules are imaged in the transmission electron microscope (TEM), their inherent handedness is lost because the three-dimensional (3D) structure is projected onto a two-dimensional (2D) plane, and identical 2D projections can be made from either 3D enantiomer. Nevertheless, tilt experiments in the TEM can be used to determine handedness. These experiments have been perfor...
