While considering the chameleon scalar field model with spatially flat FLRW background, we investigate late-time acceleration phase of universe, wherein apply typical potential usually used in this model. Through setting some constraints on free parameters model, indicate that non-minimal coupling between matter and such a should be strongly coupled order to have an accelerated expansion univer...

We characterize the geometrical and topological aspects of a dynamical system by associating a geometric phase with a phase space trajectory. Unlike Berry’s phase, the path underlying this “anholonomy” is not in parameter space, but in a projective space of the phase space, which directly characterizes the geometry of the trajectories. Using the example of a non-linear driven damped oscillator,...

Taiwan, because of its location, is a flood prone region and is characterised by typhoons which brings about two-thirds to three quarters of the annual rainfall amount. Consequently, enormous flows result in rivers and entrain some fractions of the grains that constitute the riverbed. Hence, the purpose of the study is to quantify the impacts of these enormous flows on the distribution of grain...

Using empirical data from an Internet/WAN distributed Web response time measurement system, this paper explores the relative applicability and usefulness of the geometric mean and geometric standard deviation, and introduces the lognormal distribution for quantifying the response time measurements. These statistics are particularly useful in the areas of Web content performance comparison and S...

OBJECTIVES There are no data in the literature with regard to the acute effects of different styles of music on the geometric indices of heart rate variability. In this study, we evaluated the acute effects of relaxant baroque and excitatory heavy metal music on the geometric indices of heart rate variability in women. METHODS We conducted this study in 21 healthy women ranging in age from 18...

Geometric uncertainty refers to the deviation of the geometric boundary from its ideal position, which may have a non-trivial impact on design performance. Since geometric uncertainty is embedded in the boundary which is dynamic and changes continuously in the optimization process, topology optimization under geometric uncertainty (TOGU) poses extreme difficulty to the already challenging topol...
