Quadratic Equation Discriminant

Two mass variable equations with "Aerospace 3Dof Simple Variable Mass Blockset" are compared in a 1Dof frictionless environment. Initial conditions are given in Model Callbacks.Results showed that "Aerospace 3Dof Simple Variable Mass Blockset" uses the incorrect equation.

In this paper i try to associate a linear dynamical system dX/dt=AX to the PDE wave equation.So i discretize the space to step h,and set the limited develpment.it is well application also for spherical wave.J.C Willems gives good standing from ODE to PDE,and From PDe to ODE.

We use the genetic algorithm (gatool) to determine the three parameters of the simple Antoine equation and the six parameters of the Modified Antoine Model. Predictions are in perfect agreement with experimental data of vapor pressure of ethanol versus temperature for a temperature range from...

A control strategy for optimal operation of a hydroelectric dam is found through nonlinear and quadratic programming techniques. We use symbolic math to formulate an original model of the hydroelectric dam and then optimize the operation schedule using FMINCON. We then show how improvements can...

We solve a binary distillation problem using the solution of a Riccati equation. We find that four plates are needed to achieve the desired product purity. We also compute the number of stages with the classical approach by stepping off stages using the equilibrium curve and the operating line....
