Although Penn Station gets only a passing mention in the novel, the set designer Eugene Lee recognized that all the dynamic forces of the era--steel, steam, machines, space, speed, and the journeying citizen--came together at this intersection.
Furthermore, the paper has indicated that traffic density is insensitive to the coefficient of variation of space speed.
The CME travel time essentially depends on the accurate estimate of the space speed of CMEs and the background solar wind speed; these have been estimated based on single view (SOHO) as well as from multiple views (SOHO and STEREO).
For instance, while context of a user is being learnt, for instance, from documents and ontologies [60], multiple context attributes like environmental and other properties (time, location, temperature, space, speed, etc).
From the radio observations we can infer that the plane of the sky speed of the CME is smaller than the space speed by at least a factor of 2, consistent with the location of the eruption at N21 W08.
The method firstly converts time mean speed to space mean speed by introducing the coefficient of variation and standard error of space speed, and then, acquires traffic density through the relationship between traffic flow, density, and space mean speed in traffic flow theory.
