In this paper, the Unified Power Flow Controller (UPFC) is enhanced with a Chaotic Particle Swarm Optimization (CPSO) Damping Controller in order to mitigate the Low Frequency Oscillations (LFO) in a Single Machine Infinite Bus (SMIB) power system. The designed damping controller is an optimized lead-lag controller, which extracts the speed deviation of the generator rotor and generates the out...

Recent experiments on the spherical tokamak have discovered the conditions to create a powerful plasma and ensure easy shaping and amplification of stability, high bootstrap current and confinement energy. The spherical tours (ST) fusion energy development path is complementary to the tokamak burning plasma experiment such as NSTX and higher toroidal beta regimes and improves the design of a po...

Introdouction: Dentinal hypersensitivity (DH) is one of the most painful chronic problems reported in dental offices. Various methods have been applied for the treatment of DH. However, majority of them are either ineffective or last for a short period of time. It has been reported that lasers, particularly Neodymium- doped: Yttrium Aluminum Garnet laser (Nd: YAG), can be helpful in the treatme...

aim and background:   knee osteoarthritis (oa) is a prevalent and disabling disease. periarticular corticosteroid injection has been traditionally used for the pain control in these patients. recently low power laser has been introduced as a therapeutic option. this study was conducted to evaluate the efficacy of low power laser added to periarticular steroid injection for long-term treatment o...

This paper is aimed at analyzing the possible power options and configurations for remote locations in the oil and gas industry with the view of proposing a cost effect power supply option suitable for the different operational requirements at these remote locations. It reviews the different power options available and presents selection criteria for the optimum choice of power generation techn...

A novel low power and Positive Feedback Adiabatic Logic (PFAL) combinational low power circuit is presented in this paper. The power consumption and general characteristics of the PFAL combinationallow power circuit arethen compared against two combinational low power circuit Efficient Charge Recovery Logic (ECRL), Conventional CMOS. The proposed PFAL combinational low power circuit design was ...

In this paper, a new identification of the Lagrange multipliers by means of the Sumudu transform, is employed to  btain a quick and accurate solution to the fractional Black-Scholes equation with the initial condition for a European option pricing problem. Undoubtedly this model is the most well known model for pricing financial derivatives. The fractional derivatives is described in Caputo sen...

management of solid waste (flyash) has attained an apparent scenario for scientific & strategic concern in india due to large-scale dependence on coal-based thermal power plants. waste utilization as the best option of pollution-prevention and disaster risk strategy has been worked out during previous decades to open doors for flyash utilization on various sectors of developmental and manuf...

We propose a hybrid option for the first local oscillators (LOs) of ALMA in which a direct photonic LO driver is used to drive cold multipliers. The photomixer using NTT uni-travelling carrier photodiode has been demonstrated to have high power of 2 m W at 100 GHz and low amplitude noise of < 7 − 17 K/μW in the frequency range of 98 − 105 GHz. This option simplifies the LO part of the cartridge...

This study investigates the algorithm of effective option trading strategy based on the superior volatility forecasts using actual option price data in Taiwan stock market. Forecast evaluation supports the significant incremental explanatory power of investor sentiments on the fitting and forecasting of future volatility to its adversarial multiple-factor model, especially the market turnover a...
