The FitzHugh–Nagumo (FHN) model, from computational neuroscience, has attracted attention in nonlinear dynamics studies as it describes the behavior of excitable systems and exhibits interesting bifurcation properties. accurate estimation model parameters is vital to understand how solution trajectory evolves time. To this end, we provide a forward sensitivity method (FSM) approach quantify mai...

In this paper, we propose a new cure rate survival model, which extends the model of Rodrigues et al. (2011) by incorporating a dependence structure between the initiated cells. To create the correlation structure between the initiated cells, we use an extension of the generalized power series distribution by including an additional parameter ρ (inflated-parameter generalized power series (IGPS...

soil conservation service (scs) adjusted the kostiakovs infiltration model by adding a constant coefficient, for improvement of estimation. the improved model has three constant parameters, which are difficult to calculate. so scs has taken the third constant parameter as equal to 0.65-0.7 cm to simplify the estimation. this parameter varies in different soil and often outranges the scs estimat...

A novel method for exploring the power system saddle node and Hopf bifurcation boundaries in the space of active and reactive powers has been proposed in the paper. This method is of iterative type with an eigenvalue sensitivity approach used to find a first bifurcation point and a parameter continuation technique used to locate the entire saddle node and Hopf bifurca-tion boundaries. It has be...

in this paper, we present a new method to determine the optimal location and parameter settings of unifiedpower flow controller (upfc) for removing voltage violations and transmission lines overloading. upfc isconsidered as the most powerful member of the facts devices, that it can control shunt and series power flow.this option gives to upfc the power to control the voltage profile and transmi...
