The concepts of relative velocity and acceleration, deviation velocity and acceleration and relative momentum of point particles in spaces (manifolds), the tangent bundle of which is equipped with a transport along paths, are introduced. If the tangent bundle is endowed also with a metric, it gives rise also to the notion of a relative energy. Certain ties between these quantities are considere...

acquired using TPM in basal, midventricular, and apical short axis slices. B: Data for each subject were mapped onto an AHA 16-segment model. For each segment, the velocity time courses were used to derive systolic (TTPSys) and diastolic (TTPDia) times-to-peak velocity as illustrated for radial and long-axis velocities. C: Systolic and diastolic dyssynchrony was assessed by calculating the stan...

A widely used morphometric method (Macdonald et al. 1998) to calculate the zero-plane displacement (zd) and aerodynamic roughness length (z0) for momentum is further developed to include vegetation. The adaptation also applies to the Kanda et al. (2013) morphometric method which considers roughness-element height variability. Roughness-element heights (mean, maximum and standard deviation) of b...

[1] This paper describes the multiscale, statistical state of the speed observed near 60 AU from mid-1999 to mid-2000 by Voyager 2 (V2), and it shows that a multifluid MHD model can explain the basic features of these observations. The probability distribution functions (PDFs) of the running speed differences (dVn) on scales from 1 day to 256 days provide a relatively complete description of so...

Estimation of parametric variance functions for assays relies on transformation of standard deviations based on replication at each concentration. The quality of such estimates has been shown to have direct impact on the quality of inference based on the fitted calibration curve. The theory of Davidian and Carroll (1987) is used to demonstrate that ignoring unequal replication can lead to bias ...

Vehicle verification has very importance in this year because of its efficiency to avoid collision and less cost. Vehicle verification is difficult since the vehicle is similar in its color, shape and pose.log Gabor filter is used here as the algorithm to perform this task. Previously Gabor filter had been used. But since it has some drawbacks log Gabor filter introduced. Energy feature is choo...

Retrograde tracer injections in 29 of the 91 areas of the macaque cerebral cortex revealed 1,615 interareal pathways, a third of which have not previously been reported. A weight index (extrinsic fraction of labeled neurons [FLNe]) was determined for each area-to-area pathway. Newly found projections were weaker on average compared with the known projections; nevertheless, the 2 sets of pathway...

We investigate the evolution of the velocity distribution function of a granular gas composed of viscoelastic particles in the homogeneous cooling state, i.e. before clustering occurs. The deviation of the velocity distribution function from the Maxwellian distribution is quantified by a Sonine polynomials expansion. The first non-vanishing Sonine coefficient a2(t), reveals a complex time depen...

fractures are considered as one of the important structures in fractured reservoirs due to their effect on fluid currents and reservoirparameters such as porosity and permeability. fracture parameters can only be directly calculated with core and image logs. cores haveserious limitations, so image logs are the best method. the aim of this study is the systematic fractures analysis of the asmari...
