Hydrodynamic models are important to many coastal engineering designs and application,especially addressing sediment and water *** this study,MIKE 21 two-dimensional(2d)hydrodynamic model based on the flexible mesh(FM)technique was used to simulate the surface currents forced by tides and winds in Kanyakumari *** model results of the tidal level along shore and cross shore currents are agreed well with measured data in Kanyakumari *** major components of tides and currents are analyzed by harmonic analysis *** mean square error(rMSE)values for the measured and model tides(0.017 m and 0.079 m)and currents(0.025 m/s and 0.009 m/s)during the northeast(NE)and southwest(SW)monsoon period are calculated.A series of scenario runs for NE and SW monsoon season are used to understand the regional *** model result shows that the Kanyakumari coast is dominated by tides and surface currents flow,which are influenced by the seasonal reversal wind *** around this coastal water have been evidenced small scale cyclonic and anti-cyclonic eddies ranged from∼55 to 120 km in *** cyclonic and anti-cyclonic eddies are mostly appeared in near Kanyakumari and SE coast of Kerala due to local/remotely generated forces.

In neurodegenerative disorders such as Parkinson＇s disease （Pd）, deep brain stimulation （dBS） is a desirable approach when the medication is less effective for treating the symptoms. dBS incorporates transferring electrical pulses to a specific tissue of the central nervous system, obtaining therapeutic results by modulating the neuronal activity of that region. dBS has certain advantages such as reversibility and adjustability features over medication, since the neuronal firing patterns can be recorded and used to alter the parameters of the dBS signal （Benabid et al., 2009）. One of the dBS indications is its ability to suppress the abnormal neuronal activity to treat symptoms like tremor, akinesia and dystonia.

A new runge-Kutta （PK） fourth order with four stages embedded method with error control is presentea m this paper for raster simulation in cellular neural network （CNN） environment. Through versatile algorithm, single layer/raster CNN array is implemented by incorporating the proposed technique. Simulation results have been obtained, and comparison has also been carried out to show the efficiency of the proposed numerical integration algorithm. The analytic expressions for local truncation error and global truncation error are derived. It is seen that the rK-embedded root mean square outperforms the rK-embedded Heronian mean and rK-embedded harmonic mean.

In this paper,an optimized Genetic Algorithm(GA)based internal model controller-proportional integral derivative(IMC-PId)controller has been designed for the control variable to output variable transfer function of dc-dc boost converter to mitigate the effect of non-minimum phase(NMP)behavior due to the presence of a right-half plane zero(rHPZ).This rHPZ limits the dynamic performance of the converter and leads to internal *** IMC PId is a streamlined counterpart of the standard feedback controller and easily achieves optimal set point and load change performance with a single filter tuning parameterλ.Also,this paper addresses the influences of the model-based controller with model plant mismatch on the closed-loop *** conventional IMC PId design is realized as an optimization problem with a resilient controller being determined through a genetic *** results suggested that GA–IMC PId coheres to the optimum designs with a fast convergence rate and outperforms conventional IMC PId controllers.
