* Visibility graph analysis

Visibility graphs may be used to find Euclidean shortest paths among a set of polygonal obstacles in the plane: the shortest path between two obstacles follows straight line segments except at the vertices of the obstacles, where it may turn, so the Euclidean shortest path is the shortest path in a visibility graph that has as its nodes the start and destination points and the vertices of the obstacles.

Visibility graphs may also be used to calculate the placement of radio antennas, or as a tool used within architecture and urban planning through visibility graph analysis.

Visibility graphs of simple polygons must be Hamiltonian graphs: the boundary of the polygon forms a Hamiltonian cycle in the visibility graph.

Visibility graph analysis ( VGA ) is a method of analysing the inter-visibility connections within buildings or urban networks.

Visibility graph analysis was developed from the architectural theory of space syntax by Turner et al.

Visibility is vital and that face should immediately allow you to identify a Kia even from a distance.

Visibility can vary from nearly unlimited to low, or non-existent, and can go from one extreme to the other in a single dive.

Visibility from the driver's seat and passenger seat was better due to the lower instrument panel design of the front window and a large windshield.

On other aircraft ( the Boeing 787, for example ) the HUD guidance computation for Low Visibility Take-off ( LVTO ) and low visibility approach comes from the same flight guidance computer that drives the autopilot.

Savi has been the primary provider of active RFID for the U. S. Department of Defense since 1993, and helped build the DoD's In-Transit Visibility network.

Visibility minimums of 1 / 2 mile ( runway visual range of 2, 400 feet ) are possible with a CAT I ILS approach supported by a ALS, and 3 / 8 mile visibility visual range is possible if the runway has high-intensity edge lights, touchdown zone and centerline lights, and an ALS that is at least long ( see Table 3-5a in FAA Order 8260. 3b ).

Visibility continued to be limited, and Greg was never able to get above a thousand feet.

* Selective Visibility: The simple ability to see what is occurring on stage.

In 1990, amendments to the Clean Air Act established the Grand Canyon Visibility Transport Commission ( GCVTC ) to advise the US EPA on strategies for protecting visual air quality on the Colorado Plateau.

Visibility may be poor, because of sediments or algae in the water and lack of light penetration.

Everyday Surveillance: Vigilance and Visibility in Post-Modern Life.

Visibility can be a bit low, especially after rough weather, but the coral is excellent and the variety of fish superb.

Visibility also depends on the eyes of the observer and / or the instruments used.

Special light-diffusing optics and a colored fresnel lens create the indication. Signals such as the 3M High Visibility Signal and McCain Programmable Visibility signal utilize light-diffusing optics and a powerful fresnel lens to create the signal indication.
