The announcement of the Yocto project (see Resources) refers to a component called pseudo that allows non-root users to run project builds that might otherwise require root privileges.

There is the non-detected component in the output of geophone. This component is called the pseudo signal response, which seriously affects the quality of seismic data.

A new method of numerical simulation for condensate oil-gas reservoir is presented in this paper, and an equation-of-state multicomponent model is set up by using pseudo-component theory.
