1. Frames of Reference: The Basics
... 22.Reference Frames . ... To derive the motion of a penny dropped inside an airliner moving at 600 miles/hr (about 1000 km/hr)--should we calculate it with respect to the interior of the airliner, or with respect to the ground? ... And if a similar penny is let go inside an orbiting spaceship--should its motion be calculated relative to the interior of the spaceship, or relative to the Earth outside? ... How do observations differ in the two frames--the airliner cabin and the Earth? ...

2. Relative Corrections
... epiclccorr (epiclccorr-1.0.8) [?? ... epiclccorr will treat all these corrections individually, developing and designing specific algorithms to correct the Relative Corrections . GTIs correction will be calculated using the GTI extensions located in the time series file, if any. ... Exposure correction is the time inside each frame where the CCD is taking data correctly (no counting or MIP problems). ... This correction will be calculated using the Live Time and Frame Time values of each mode. ...

3. ASP: A Taste of Real Astronomy ? The ESA/ESO Astronomy Exercises
The ESA/ESO Astronomy Exercise Series 2 . The Distance to Messier 100 as Determined by Cepheid Variable Stars . ... The small variations in distance to the individual Cepheid variable stars in the Cloud are negligible compared with the much larger distance to the SMC. ... In this way Cepheid variable stars can be used as one of the 'standard candles' in the Universe that act either as distance indicators themselves or can be used to calibrate (or set the zero point for) other distance indicators. ...

4. Determination of the relative orientation between radio and dynamical reference
... The experience of determination of the link between radio sources and dynamical reference frames is presented. To obtain this connection we used a series of very long baseline interferometry (VLBI) observations of the spacecraft Phobos-2 and angularly nearby quasars. ... The dynamical reference frame is determined by equator and equinox of these ephemerides. ... References . ... The relative orientation of the radio and dynamical reference frames can be described by a sequence of three rotations . ...

11. Frictional heating [Oulu]
... Electric field is a potential heat source for ionospheric particles (Rees, 1989). It is due to the fact that, under the action of an electric field, charged particles drift relative to one another and relative to neutral particles. ... This is called frictional heating. ... However, the effect of frictional/Joule heating of neutrals in the auroral electrojet region can lead to upward neutral wind in a region of high electron densities and strong electric fields (Winser et. al., ...

13. Relative pathnames
. You can define a file or directory by its location in relation to your current directory . The pathname is given as / (slash) separated list of the directories on the route to the file (or directory) from your current directory. A .. (dot dot) is used to represent the directory immediately above the current directory. In all shells except the Bourne shell, the ~ (tilde) character can be used as shorthand for the full pathname to your home directory. Examples . Did You Know? .

The text of the "outer" box (at the end of line 1, halfway into line 2, and halfway into line 3) is shifted upward 12px. The text of the "inner" box, thought shifted upward as well, has been relatively positioned so that it lies in its normal flow position at the end of line 2. ... The lines, as they appear in the image, contain: Start 1 Beginning of body contents. 2 of outer contents. Inner contents. ...
