Simulation of Impulse Sources in Models with Distributed Parameters
نویسندگان
چکیده
The impulse sources are heat impulses or force impulses lengthways the arrangements. They are represented mathematically by Delta functions and Dirac impulses of finite duration. Conventional fitting conditions are compared hereby. The successive time integration of the PDE provides a system of two equations. A Dirac impulse changes into a Ramp function this way and the Delta function becomes the Heavyside function. This is implemented by a discrete event. A smoothing of finite impulses, by putting the analytical integration in front, is of numeric advantage. The numeric integration, using the method of lines, and the visualization are carried out by MATLAB. Temperatures and vibrations are investigated.

متن کاملModified Maximum Likelihood Estimation in First-Order Autoregressive Moving Average Models with some Non-Normal Residuals
When modeling time series data using autoregressive-moving average processes, it is a common practice to presume that the residuals are normally distributed. However, sometimes we encounter non-normal residuals and asymmetry of data marginal distribution. Despite widespread use of pure autoregressive processes for modeling non-normal time series, the autoregressive-moving average models have le...
