Solar Storm Type Classification Using Probabilistic Neural Network compared with the Self-Organizing Map [PDF]

open access: yes, 2012
One of the task of the LAPAN is making observation and forecasting of solar storms disturbance. This disturbances can affect the earths electromagnetic field that disrupt the electronic and navigational equipment on earth.

Wind measurement system [PDF]

open access: yes, 1976
A system for remotely measuring vertical and horizontal winds present in discrete volumes of air at selected locations above the ground is described. A laser beam is optically focused in range by a telescope, and the output beam is conically scanned at ...

External bulb variable volume maser [PDF]

open access: yes, 1978
A maser functioning as a frequency standard stable to one part in 10 to the 14th power includes a variable volume, constant surface area storage bulb having a fixed volume portion located in a resonant cavity from which the frequency standard is derived.
