A wavelength-selective 2-order 1-by-8-port optical multicast filter bank is demonstrated utilizing microring resonators, achieving ~2.6× faster roll-off than 1-order design while maintaining highly uniform responses among all eight drop ports. OCIS codes: (130.3120) Integrated optics devices; (230.5750) Resonators; (230.0250) Optoelectronics.
با توجه به اینکه دیکلوفناک سدیم تنها فرم تزریقی موجود در بازار دارویی ایران است و اخیرا مواردی از عوارض این دارو دیده شده و خطرناکترین عارضهء این دارو foot drop ناشی از تزریق عضلانی در ناحیهء گلوتئال است جمع آوری، مطالعه و گزارش این موارد ضروری به نظر می رسید. اهداف مطالعه: اهداف کلی این مطالعه عبارت است از مطالعه و گزارشی منسجم از موارد foot drop متعاقب تزریق عضلانی دیکلوفناک سدیم در ناحیهء گل...
We propose an approach to a wavelength-selective 1×N port optical broadcast network demonstrating the approach in a 1×8 port parallel optical drop filter bank utilizing adiabatic micro-ring tunable filters. The micro-ring filters exhibit first-order 92.7±3.7 GHz full width at half-maximum bandwidths with a 36.2 nm free spectral range, low-drop power variation (0.11 dB), and aggregate excess los...
Background and Objectives: The goal of the present study was to develop nanofibrous media filters containing MgO nanoparticles for future application in removing particles from gas stream. Materials and Methods: Electrospun nanofibers were fabricated using experimental design prepared by Response Surface Methodology. Optimization of electrospinning parameters was conducted for achieving the ...
We report on the fabrication of a grating-based add–drop filter in SiON planar waveguide technology. We achieved apodization of the Bragg grating by concatenating subgratings with various duty cycles. We present the theoretical and experimental dependence of the coupling coefficient on the duty cycle, which leads to a minimum coupling coefficient of 30%. With a breeder genetic algorithm we were...
queueing model. We define a new concept of trunk as a group of voice traffic with identical destination and DSCP. It is assumed that at least one trunk should be established between the ingress router and corresponding egress router. Each trunk has a different voice traffic arrival rate and mean service timc. We assume that there are P types of queues. In a queue of typc lc (k = I, 2, ..., P), ...
