	Stationary process - Wikipedia, the free encyclopedia
		In the mathematical sciences, a stationary process (or strict(ly) stationary process) is a stochastic process whose probability distribution at a fixed time or position is the same for all times or positions.
		Processes are described as trend stationary if they are a linear combination of a stationary process and one or more processes exhibiting a trend.
		A discrete-time stationary process where the sample space is also discrete (so that the random variable may take one of N possible values) is known as a Bernoulli scheme.

	PlanetMath: stationary process
		A weaker form of the above is the concept of a covariance stationary process, or simply, a stationary process
		A stochastic process that is not a stationary process is called an evolutionary process.
		This is version 2 of stationary process, born on 2005-07-05, modified 2005-07-05.

	Stationary process concepts
		As in the case of mobile applications, the fuel (hydrogen) for the fuel cell must also be produced from a primary energy carrier for stationary applications.
		The complexity of such a process - the figure shows a process with heated reforming and hydrogen separation for gas cleaning - requires an exact analysis of all individual steps and their interactions.
		Coupling stationary feed gas production with the fuel cell of a vehicle for electricity generation is conceivable, if - and this condition prevails - the vehicle is not in the driving mode.

	Stationary and Nonstationary Random Processes
		From the definition of a random process, we know that all random processes are composed of random variables, each at its own unique point in time.
		Because of this, random processes have all the properties of random variables, such as mean, correlation, variances, etc..
		The most important result of this statement, and the identifying characteristic of any first-order stationary process, is the fact that the mean is a constant, independent of any time shift.

	Process Engineering \| Blackmer \| Process Engineering: Blackmer debuts SX3 stationary process pump
		The SX3 Series stationary process pump is ideal for use in the process market on applications such as solvents, chemicals, sulfates, vegetable oils, biodiesel, urea and many acids.
		The new SX3 is a modified version of the STX3 transport pump, which was originally introduced in 1999 and designed for the transport industry, specifically for corrosive and non-corrosive fluids that were not compatible with cast iron pumps.

	Stationary - Wikipedia, the free encyclopedia
		Look up stationary in Wiktionary, the free dictionary.
		The word is sometimes confused with stationery, meaning paper or office supplies.
		However also see stationary word origin, which shows that "stationary" is the original spelling and is also the most common spelling today.
