Estimating wind energy at a specific site depends on how well the real data in that area can be represented using an appropriate distribution function. In fact, sites differ extent to which their from one region another, despite widespread use of Weibull function representing speed various locations world. this study, new probability model (normal PDF) was tested implement several Jordan. The r...

Circadian clocks generate 24-hr rhythms in physiology and behavior. Despite numerous studies, it is still uncertain how circadian rhythms emerge from their molecular and neural constituents. Here, we demonstrate a tight connection between the molecular and neuronal circadian networks. Using fluorescent transcriptional reporters in a Drosophila ex vivo brain culture system, we identified a recip...

Meals are clusters of feedbunk visit (BV) events that are differentiated from the next meal by a nonfeeding interval that is longer compared with the nonfeeding intervals within a meal. The longest nonfeeding interval considered to be part of a meal is defined as the meal criterion. The objective of this study was to determine which combination of 2 probability density functions [(PDF): Gaussia...

let $n$ be any positive integer, the friendship graph $f_n$ consists of $n$ edge-disjoint triangles that all of them meeting in one vertex. a graph $g$ is called cospectral with a graph $h$ if their adjacency matrices have the same eigenvalues. recently in href{http://arxiv.org/pdf/1310.6529v1.pdf}{http://arxiv.org/pdf/1310.6529v1.pdf} it is proved that if $g$ is any graph cospectral with $f_n$...

We introduce a new method to measure frequency separations and mode lifetimes of stochastically excited and damped oscillations, so-called solar-like oscillations. Our method shows that velocity data of the red giant star ξ Hya (Frandsen et al. 2002) support a large frequency separation between modes of roughly 7 µHz. We also conclude that the data are consistent with a mode lifetime of 2 days,...

With the advent of commercial image-guided radiotherapy, daily correction of the setup uncertainty is feasible. It is beneficial to understand the dependence of the probability density function (pdf) of the corrected setup variation on the action level, localization uncertainty and re-positioning uncertainty so that an appropriate action level is used. Also, that pdf can be used in treatment pl...
