Vorticity equation

summary on the intellectual merits and broader impact of the project. The PI initiates a new approach (in items 2,5, 6), using the precise large time asymptotic behavior of solutions of a parabolic equation to study the geometric property of K manifolds, and to solve the Poincar Lelong equation. The method is effective in proving sharp and optimal result. The method reminisces the celebrated ergodic theorem of Birkhoff which connects the space average of a continuous function on the phase

Brief Summary of Thesis: In this thesis, Homotopy analysis method (HAM) has been applied to obtain the solutions of nonlinear differential equations arising in fluid flow and Heat transfer. This method

On contrary flexible robot position is not constant and hence partial differential equation is used to represent the distributed nature of position. Further due to sudden change in payload there may be a large variation in manipulator parameters. Thus control with constant gain controllers is difficult and adaptive methods must be used

Analysis Method to Fredholm integral equations of the second kind. An analytical method solving linear and nonlinear equations.The Homotopy Analysis Method provides an efficient and powerful tool in solving integral equations.The method provides a great freedom in choosing an auxiliary parameter h, an auxiliary linear operator L,an auxiliary nonlinear operator N, to analyze strongly linear and nonlinear problems. Application of the method to Fredholm integral equations of the second kind is analyzed which

know this to be certain, mathematicians believe that by using math, specifically differential equations, they can predict how things such as population, the stock market, and the weather can be somewhat accurately predicted. In order to decide whether differential equations can predict future events, it is important to know exactly what a differential equation is. A differential equation is an equation involving derivatives of a function or functions.. The functions usually represent some quantities

of a single independent variable. This reduces the partial differential equation to a system of ordinary differential equations, each being a function of a single independent variable. For the transient conduction in a plain wall, the dependent variable is the solution function θ(X, F0), which is expressed in terms of θ(X, F0) = F(X)G(t), and the application of this method results in to the two ordinary differential equations, one in terms of X and the other one in F0. Now we demonstrate the use

CHAPTER 1 INTRODUCTION Definition of Differential Equation A differential equation is an equation which consists of derivatives or differentials of one or more dependent variables with respect to one or more independent variables (Abell & Braselton, 1996). Differential equation generally can be classified into two, which are ordinary differential equation and partial differential equation. If a differential equation consists of ordinary derivation of one dependent variable with respect to only one

linear differential equations with variable coefficients. The solutions usually take the form of power series; this explains the name Power series method. We review some special second order ordinary differential equations. Power series Method is described at ordinary points as well as at singular points (which can be removed called Frobenius Method) of differential equations. We present a few examples on this method by solving special second order ordinary differential equations. Key words ; Power

problem. In theory, forward differencing and Dufort-Frankel methods were explicit method, and backward differencing and Crank Nicolson were implicit methods. It was suggested that the implicit method was more stable than the explicit as it solved the equation involving both the current state and the next step rather than just using the current state. The dx, dt were found using Fig.2. dt was found where the Crank Nicolson line started to fluctuate heavily at around 14s (Fig.3), and dx was found when
