The Observer Kearny Nj

This class implements the observer design pattern. Acting as a registration hub, it fires simple Events when requested.

This is a Python implementation of the observer pattern. It defines a one-to many dependency between objects so that when one object changes state, all its dependents are notified and updated automatically.

Imagine someone have came to your PC and is trying to do something with it. He will be very surprised to see that no icons can be opened, no windows can be accessed... and the pair of strange eyes is watching his every move!

sun = sun_position(time, location)This function computes the sun position (zenith and azimuth angle at the observer location) as a function of the observer local time and position.It is an implementation of the algorithm presented by Reda et Andreas in: Reda, I., Andreas, A. (2003) Solar position...

The Ejs Celestial Globe model simulates the Two Sphere Universe theory of the Ancient Greeks. This theory supposes the stars to be fixed on the surface of a Celestial Sphere, with the spherical Earth at the center of this sphere. The simulation shows the motion of Sun and stars in this model, as...

MilDotCalc helps determine the distance to an object by using the Mil relation formula. A mil, or mil-radian, is an angular unit of measure. If one knows the width or height to a distant object being observed with a mil ranging reticle equipped optic (binocular, rifle scope, etc.), then...

ELEV = GETELEVATIONANGLE(GR,H1,H2,REFFECTIVE) Determines the elevation angle of a target based on ground range (GR), altitude of the observer (H1) and the altitude of the target (H2), and the effective radius of the Earth (REFFECTIVE). Ground range and rEffective are in meters. Altitudes are in...

The Equatorial Coordinates model displays the position of a star in equatorial (Right Ascension/Declination --- RA/Dec) coordinates. The horizon is shown along with the four cardinal directions (N, E, S, and W). The Latitude slider changes the latitude of the observer which is shown by the change...
