1. introduction wind is one of the important meteorological parameters which have an extensive application in environmental studies. the winds have various spatial and temporal scales regarding to their characteristics and structures. sistan wind as an outstanding low level flow in eastern iran is playing an important role to creation of local and regional climatic features. the sistan wind ini...

The cluster randomised trial (CRT) design is widely used to evaluate interventions targeted at the cluster level and helps alleviate contamination within clusters. CRTs usually require large sample sizes, although matched pair CRTs can limit this problem. The stepped wedge design (SWD) extends CRTs, in cases where it is expected that the intervention will do more good than harm and/or, for logi...

Network mechanisms relevant for the generation, maintenance and termination of spike-wave discharges (SWD), the neurophysiological hallmark of absence epilepsy, are still enigmatic and widely discussed. Within the last years, however, improvements in signal analytical techniques, applied to both animal and human fMRI, EEG, MEG, and ECoG data, greatly increased our understanding and challenged s...

Shingled Magnetic Recording (SMR) is a promising technique for increasing hard disk drive (HDD) capacity by overlapping adjacent tracks, which enforces writes to be performed in a sequential manner in order not to destroy the valid data in the following neighboring tracks. In this paper we introduce T-STL, a Track-based Shingled Translation Layer for autonomous Shingled Write Disks (SWDs). T-ST...

Reliable wind modelling is of crucial importance for wind farm development. The common practice of using sector-wise Weibull distributions has been found inappropriate for wind farm layout optimization. In this study, we propose a simple and easily implementable method to construct joint distributions of wind speed and wind direction, which is based on the parameters of sector-wise Weibull dist...

pollination is the mechanical transfer of male pollen of a flower on the female stigma.this process has a fundamental role to survive the plants species.since this process is invisible ,its importance has been ignored.insufficient pollination can be harmful for the farmer instead of being useful.pollination can be done via some ways.the most important ways are done by insects and wind.pistachio...

Deconvolution interferometry successfully recovers the impulse response between two receivers without the need for an independent estimate of the source function. Here we extend the method of interferometry by deconvolution to multicomponent data in elastic media.As in the acoustic case, elastic deconvolution interferometry retrieves only causal scattered waves that propagate between two receiv...

The physical development of cities is always faced with natural barriers. The physical development of the city of Zabol, located in the Sistan plain, is threatened specifically with the development of sand dunes. For this reason, the region’s drought conditions were investigated and the standardized precipitation index was calculated. The results showed that with the drying of Hamoon Lake, the ...

BACKGROUND Understanding how environmental conditions, especially wind, influence birds' flight speeds is a prerequisite for understanding many important aspects of bird flight, including optimal migration strategies, navigation, and compensation for wind drift. Recent developments in tracking technology and the increased availability of data on large-scale weather patterns have made it possibl...
