Fiber characteristics play a critical role in the propagation of short optical pulses. To implement a temporal Optical Code-Division-Multiple-Access (OCDMA) solution, it is necessary to take into account the linear and nonlinear effects resulting from the propagation inside the fiber. In this paper, we study the importance of these phenomena along with the performance of the network. This study...

This paper presents a new circular photonic crystal fiber (C-PCF) for effective dispersion compensation covering E to L wavelength bands ranging from 1360-1625 nm. To investigate its guiding properties, finite element method (FEM) with a perfectly matched layer absorbing boundary condition is used. From our numerical simulation, it is found that the designed C-PCF simultaneously shows a large n...

Analyzing medical images is the most challenging task in medical image processing. Computer Aided Detection (CAD) tool is the aid for the radiologists in analyzing such images for the effective detection and diagnosis of the disease. Such a CAD tool consists of Preprocessing, Segmentation and detection processes. In this study we have improved the preprocessing by using the Selective Median Fil...

Enzyme production varies in different fermentation systems. Enzyme expression in different fermentation systems yields important information for improving our understanding of enzymatic production induction. Comparative studies between solid-state fermentation (SSF) using agro-industrial waste wheat bran and submerged fermentation (SmF) using synthetic media were carried out to determinate the ...

Crystal orientation is the key aspect of epitaxially grown ceramic thin films because it significantly affects their properties. In this study, evaluation thin-film using scanning transmission electron microscopy moiré fringes (SMF) demonstrated. The SMF result from combination crystal lattice in bright-field image and raster scanned beam. As reflect against lines, possible to observe distribut...

A new approach to suppressing the four-wave mixing (FWM) crosstalk by using the pairing combinations of differently linear-polarized optical signals was investigated. The simulation was conducted using a four-channel system, and the total data rate was 40 Gb/s. A comparative study on the suppression of FWM for existing and suggested techniques was conducted by varying the input power from 2 dBm...

Tissue engineering is a promising research field, which aims to create new functional muscle tissue in vitro, by utilizing the myogenic differentiation potential of human stem cells. The objective of the present study was to determine the effect of static magnetic fields (SMF), combined with the use of the myogenic differentiation enhancing hepatocyte growth factor (HGF), on human satellite cel...

Numerical simulations are performed with a two-dimensional 2D fully nonlinear potential flow FNPF model for tsunami generation by two idealized types of submarine mass failure SMF : underwater slides and slumps. These simulations feature rigid or deforming SMFs with a Gaussian cross section, translating down a plane slope. In each case, the SMF center of mass motion is expressed as a function o...

In this paper, we present the simulative analysis of 32 × 2.5 Gb/s DWDM metro system with 100GHz channel spacing using SMF-28 and the Negative Dispersion Fibre (NDF) such as MetroCor which enhances the capabilities of the metropolitan area optical systems while at the same time reducing the system cost by eliminating the need of dispersion compensation. It is observed that MetroCor fibre outper...

Currently, environmental and industrial pollution along with increase and causes multiple stress conditions, the combined exposure to magnetic field and other toxic agents is recognised as an important research area, with a view to better protecting human health against their probable unfavourable effects. In the present study, we investigated the effect of co-exposure to static magnetic field ...
