Sodium bismuth titanate (Na0.5Bi0.5TiO3, abbreviated NBT) ceramics underwent concurrent successful synthesis on the basis of the hydrothermal method. A selected low-temperature process of thermal treatment was conducted to obtain a highly dense morphology, produced from high purity carbonates and oxides serving as initial precursors. The presence of well-crystallized NBT in the rhombohedral phase...
This paper discusses the crosstalk due to nonlinear effects in the Wavelength division multiplexing (WDM) systems. The performance of an eight channels WDM system is tested in presence of Four Wave Mixing (FWM) to examine the Bit Error Ratio (BER) and Optical Signal to Noise Ratio (OSNR) for different chromatic dispersion values. Based on Optical Quadrature Phase Shift Keying (OQPSK) modulation, we...
Power production of a wind turbine system is strongly dependent on both the wind regime at the site and the operating parameters of the wind turbine (design parameters). In order to evaluate the performance of a wind turbine in a given location, an accurate estimation of the turbine's Capacity Factor (CF) is required. This parameter shows the degree of match between the characteristics of the turbine...
This Paper presents a realistic approach on tackling the dynamic traffic generation problem for Wavelength Division Multiplexing Optical Networks. Given the relatively novel aspect of these networks, most research in this area was mainly focusing on the problems of routing and wavelength assignment while using fairly simplistic memoryless models for traffic generation in the simulated networks. The...
Because of the current power grid limitations, the Smart Grid is proposed as a promising alternative. It supports green energy resources and enhances power generation, delivery and distribution. For better energy management, extensive data exchange between subsystems and the control plane is needed. Since the Smart Grid uses existing technologies for communication, it inherits their defects. Targeting...
Smart Grid is viewed as an improvement over the traditional power grid that is being used today. With the ever growing communities and cities that need to be connected to the power grids, and also the increase in the number of electrical appliances in the majority of homes, there is a serious concern regarding the ability of the current power suppliers to address everyone's needs at all times. For...
An adaptation of the Ant Colony Optimization technique to the optimal sizing of analog circuits is presented. Details of the developed algorithm are given in the following. An application to the optimal sizing of CMOS inverted second generation current conveyors is presented, and comparison results with published works are highlighted. SPICE simulation results are given to show the viability of the...
