We consider Ornstein Uhlenbeck processes (OU-processes) associated to hypo-elliptic diffusion processes on finite-dimensional Lie groups: let L be a hypo-elliptic, left-invariant "sum of the squares -operator on a Lie group G with asquares -operatorproness X, then we construct OU-processes by adding negative horizontaLieradient drifts of functions U.
With limited experience to draw on, finite resources and a lack of transparency, it's not uncommon for rumours, tensions and civil unrest to overshadow the process and undermine faith in the results.
The conventional practice to predict preform shapes in hydroformimg processes based on finite-element analysis and/or experiment is an iterative procedure and requires many trials.
An approach for the optimal transition control of diffusion-convection- reaction processes based on finite-dimensional models is presented.
We consider how to choose the reproduction rates in a one-dimensional contact process on a finite set to maximize the growth rate of the extinction time with the population size.
This study introduces a welding process design tool to determine optimal arc welding process parameters based on Finite Element Method (FEM), Response Surface Method (RS M and Genetic Algorithms (GA).

Note that if X is a stationary irreducible Markov process on a finite state space, then the occupancy probability of state i, π i > 0. By choosing N tot ≫ 1 / ( min { π i } ), we may guarantee that the mean population X ¯ i for each i is as large as necessary for the Gaussian approximation to hold.
Then, nonlinear process optimization, based on finite element simulation, was conducted to obtain the optimum multi-stage deep drawing process, using a global, as well as a local, optimum search algorithm.
For quantitative analysis, a computer program for numerical simulation of the heating up and cooling down processes was developed based on Finite Differences.
In order to ensure the structural safety of plate-fin structures, a model was proposed to simulate the stress of plate-fin structures in actual operation process of LNG heat exchanger based on Finite Element Method and thermal elastic theory.
