RF Line-of-Sight provides radio path information for mapping long distance SCADA radio communications by using antenna height and topography.
In obtaining the radar horizon equations, it is common practice to assume a value for the Earth's radius that is 4/3 times the actual radius. This is done to account for the effect of the atmosphere on radar propagation. For a true line of sight, such as used for optical search and ...
These can be generated using the Unavco Plate Motion Calculator (https://www.unavco.org/software/geodetic-utilities/plate-motion-calculator/plate-motion-calculator.html). Shift the relative los-of-sight InSAR velocities into a common reference frame, by tying them to GNSS velocities. This is ...
Creepage is the shortest distance between conductor traces on a PCB along the surface of the insulation material while clearance is defined as the minimum distance through the air (line of sight) between two conductor traces. Clearance and creepage distances between two PCB conductors. ...
In Algebra class, a student becomes accustomed to using a graphing calculator to graph lines, functions and line segments. You need to be able to graph all three of these without your calculator, but if you want to quickly visualize a line segment, or a
Did you ever own an HP-41 programmable calculator? If so, I have a treat for you: a virtual HP-41 simulator-emulator!Read More… X-number-based calculators and keyboards 05.31.2006 Calculator enthusiast James Redin has a suite of web-based calculators that demonstrate the use of verbal...
We discovered the limitations of online computing tools for evaluation by applying the two calculators most commonly used in case evaluation, the National Tree Benefit Calculator and the i-Tree Design online tool. Specifically, they did not assess non-tree vegetation that covers most of a ...
