The new research described in this book demonstrates that the interplay of a host of founding conditions can frequently produce profound differences in population expansion rates and maintenance of genetic diversity in contrasting populations that differ, often only to slight degrees, in initial founding conditions. The goals of this book are twofold. First, it serves as a user's manual for the computer program NEWGARDEN (provided) designed to enable investigations, using computer generated populations, of population growth and genetic variation resulting from user-specified differences in...

An introduction to antenna Arraying in the Deep Space network

Antenna arraying is the combining of the output from several antennas in order to improve the signal-to-noise ratio (SNR) of the received signal. Now implemented at the Goldstone Complex and other Deep Space Network (DSN) overseas facilities, antenna arraying provides flexible use of multiple antennas to increase data rates and has enabled NASA's DSN to extend the missions of some spacecraft beyond their planned lifetimes.

Antenna Arraying Techniques in the Deep Space Network introduces the development and...
