In this paper we present a novel approach to estimate and analyze 3D uid structur eand motion of clouds from multi-spectrum 2D cloud image sequences. A curate cloud-top structure and motion are very important for a host of meteorolo gical and climate applications. However, due to the extremely complex nature of cloud uid motion, classical nonrigid motion analysis methods will be insu cient to s...

This article presents a mathematical paradigm called Data Driven Markov Chain Monte Carlo (DDMCMC) for object recognition. The obje ctives of this paradigm are two-fold. Firstly, it realizes traditional \hyp othesis-and-test"methods through wellbalanced Markov chain monte Carlo (MCMC) dynamics, thus it achieves robust and globally optimal solutions. Se condly, it utilizes data-driven (bottom-up...

Here, we describe a numerical method which combines a mixed nite volume//nite element formulation on unstructured triangulations and a linearized implicit method for time advancing. A particular attention has been paid to the source term implicitation. This method is applied to three typical low-Reynolds number k ? " models, namely those of Lam-Bremhorst, Nagano-Tagawa and Speziale-Abid-Anderso...

1,2,4-Trimethyl-cyclohexadiene reacts with RuCl3 nH2O in refluxing ethanol to afford quantitatively [RuCl2(1,2,4-C6H3Me3)] (1), the coordination of 1,2,4-trimethylbenzene to the ruthenium atom introducing planar chirality at the g-arene ligand. Th dinuclear complex 1 reacts with two equivalents of triphenylphosphine (PPh3) to give quantitatively, as a racemic mixture o enantiomers, [RuCl2(1,2,4...

In descriptive statistics, there are two computational algorithms for determining the variance S2, of a set of observations : Algorithm 1: S2= - , Algorithm 2: S2= , where . It is interesting to discuss, which of the above formulas is numerically more trustworthy in machine numbers sets. I this paper, based on total effect of rounding error, we prove that the second Algorithm is better...

abstractmedication errors are commonly encountered in hospital setting. intravenous medications pose particular risks because of their greater complexity and the multiple steps required in their preparation, administration and monitoring. we aimed to determine the rate of errors during preparation and administration phase of intravenous medications and the correlation of these errors with the d...

educational centers are of those types of organizations to which almost everyone refer during the life to use the services. accordingly, the suitability of safety situation in these organizations is of high importance. the present study aims at investigation of effective factors on safety management in educational-training organizations of metropolises. this study is an applied descriptive rese...

in this paper, a new alternative method for order reduction of high order systems is presented based on optimization of multi objective fitness function by using harmony search algorithm. at first, step response of full order system is obtained as a vector, then, a suitable fixed structure considered for model order reduction which order of original system is bigger than fixed structure model. ...
