Versatile digital ghz phase lock for external cavity diode lasers... Thanks to all-digital phasedetection and implementation of beat frequency pre-scaling, the apparatusrequires no microwave-range reference input, and permits phase locking atfrequency differences ranging from sub-MHz to 7 GHz (and with minor extension,to 12 GHz)....
On a molecular theory of water... The properties of the short-range reference model are then estimated by means of a simple, so-called primitive, model....
Effect of short and long range forces on the thermodynamic properties of water. a simple short range reference system... Computations of low density properties and computer simulations per-formed for several densities on three subcritical and one supercritical isotherms show that the short range reference not only reproduces the structure but approximates also the internal energy and pressure of water surprisingly well....
The 2006 cape canaveral air force station range reference atmosphere model validation study and sensitivity analysis to the national aeronautics and space administration's space shuttle... Atmospheric databases charactenzing the wind and thermodynamic environments, known as Range Reference Atmospheres (RRA), have been developed at space launch ranges by a governmental interagency working group for use by aerospace vehicle programs....
