background: the aim of the present study was to evaluate how left ventricular twist and torsion are associated with sex between sex groups of the same age. materials and methods : twenty one healthy subjects were scanned in left ventricle basal and apical short axis views to run the block matching algorithm; instantaneous changes in the base and apex rotation angels were estimated by this algor...

In this paper, we present an online FastSLAM-based algorithm for extracting three dimensional structure from the motion of a single monocular camera. Nearly all published structure from motion (SFM) algorithms are offline, that is, they require the entire data set for processing. Our algorithm exploits the notion of conditional independence in Rao-Blackwellized particles, allowing us to decoupl...

A liquid jet upon atomization breaks up into small droplets that are orders of magnitude smaller than its diameter. Direct numerical simulations of atomization are exceedingly expensive computationally. Thus, the need to perform multiscale simulations. In the present study, we performed multiscale simulations of primary atomization using a Volume-of-Fluid (VOF) algorithm coupled with a two-way ...

in this paper, matlab code for a recently developed meta-heuristic methodology, the vibrating particles system (vps) algorithm, is presented. the vps is a population-based algorithm which simulates a free vibration of single degree of freedom systems with viscous damping. the particles gradually approach to their equilibrium positions that are achieved from current population and historically b...

This paper studies connections between phase models of coupled oscil-lators and kinematic models of groups of self-propelled particles. These connections are exploited in the analysis and design of feedback control laws for the individuals that stabilize collective motions for the group.

Optimal load of mobile robots, while carrying a load with predefined motion precision is an important consideration regarding their applications. In this paper a general formulation for finding maximum load carrying capacity of flexible joint mobile manipulators is presented. Meanwhile, overturning stability of the system and precision of the motion on the given end-effector trajectory are take...

  Introduction: There are several technical features that make PET an ideal device for the noninvasive evaluation of cardiac physiology. Organ motion due to respiration is a major challenge in diagnostic imaging, especially in cardiac PET imaging. These motions reduce image quality by spreading the radiotracer activity over an increased volume, distorting apparent les...

We study the motion of a charged particle with magnetic moment in external electromagnetic fields utilizing covariant unification Gilbertian and Amperian descriptions dipole moment. Considering case current loop, our approach is verified by comparing classical dynamics limit relativistic quantum dynamics. obtain presence an linearly polarized EM (laser) plane wave field incorporating effect spi...
