The main limiting factor of a high-power and high bit-rate device performance is the onset of Non-Linear Effects which includes Stimulated Raman Scattering (SRS), Stimulated Brillouin Scattering (SBS), Four-Wave Mixing (FWM) and Self-Phase Modulation (SPM). The solution to these limiting factors are Large Mode Area (LMA) fiber. In this paper, an asymmetric,(More)
Semi supervised learning methods have gained importance in today’s world because of large expenses and time involved in labeling the unlabeled data by human experts. The proposed hybrid approach uses SVM and Label Propagation to label the unlabeled data. In the process, at each step SVM is trained to minimize the error and thus improve the prediction(More)
There is an increase in demand for high speed photodetectors in optical fiber networks for both short and long-haul applications with the continuously increasing demand in bandwidth. The main challenges in this direction is the focusing of light into small areas, as a slight misalignment in the assembly can lead to degradation of the system performance. In(More)
OBJECTIVE The aim of this study was to evaluate the effect of smokeless tobacco extract on ovariectomized female rats and to investigate the role of resveratrol in alleviating associated vascular and diabetic complications. METHODS Thirty-six female Wistar rats (8 wk old) were subjected to bilateral ovariectomy (OVX) or sham operation and randomly(More)
