in this article the relationship between the amount of seasonal rainfall (autumn, winter and spring) and climate indices in iran have been studied. the climate indices (the southern oscillation(soi),the north atlantic oscillation(nao), arctic oscillation(ao),nino 3/4,the multivariate enso index(mei),trans_ nino index(tni) and the pacific decadal oscillation(pdo) are used as independent variable...

The scaling of CMOS devices is about to reach fundamental limits, and this prompts the development of new technologies in semiconductor industry. Spin-based electronics or spintronics is considered as one of the alternatives in ‘beyond CMOS’ research. Silicon, the main element of microelectronics, appears to be the perfect material for spin-driven applications. Purely electrical spin injection ...

A 40 Gbit/s delay-line interferometer realized in SOI rib waveguide technology is presented. Across the C-band we demonstrate high uniformity, low loss, low PDL, and PDF as low as 1 GHz for the SOI interferometer.

White Spot Disease (WSD) is well known as a widespread viral disease in shrimps from 1992. Many studies focused on morphological, histopathological and epidemiological characteristic and pathogenecity of the disease but less on the determination of the severity of WSD using the histopathological features in target tissues. A generalized scheme for assigning a numerical qualitative value to sev...

Modern computing infrastructures should enable realization of converged provisioning and governance operations on virtualized computing, storage and network resources used on behalf of users’ workloads. These workloads must have ensured sufficient access to the resources to satisfy required QoS. This requires flexible platforms providing functionality for construction, activation and governance...

NATURE PHOTONICS | VOL 9 | DECEMBER 2015 | www.nature.com/naturephotonics Light consists of electromagnetic waves that oscillate in time and propagate in space. Scalar waves are described by their intensity and phase distributions. These are the spatial (orbital) degrees of freedom common to all types of waves, both classical and quantum. In particular, a localized intensity distribution determ...

This work presents a case study for the investigation of the interconnects reliability while migrating from a traditional CMOS Bulk to a SOI technology. The Bulk-to-SOI migration has been recently explored, even considering the improvements and drawbacks related to SOI, including low power advantages of this technology and low thermal properties as well. The focus point of this paper is the est...
