Visibility can be significantly reduced by becoming greasy, trapping vapour when eating hot food, swimming, walking in rain or rapid temperature changes ( such as walking into a warm building from cold temperatures outside ).

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

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 near apogee can exceed twelve hours of dwell at apogee with a much shorter and faster-moving perigee phase.

Visibility can be limited by changing conditions.

Visibility in tule fog is usually less than an eighth of a mile ( about 600 feet or 200 meters ), but can be as little as a foot ( about 30 cm.

Visibility can extend eastward to the Shenandoah National Park in Virginia.

* Visibility – Since there can be a large number of leaves in a map, it could be quite costly for the hardware to redraw the entirety of them many times a second, because areas not seen would be drawn only to be overdrawn later.

Visibility was reduced to a few yards (" It's like you were blind ", commented one observer ), making driving difficult or impossible.

Visibility at these times could become as low as a few feet ( hence the " London fogs " of movie fame ) and when combined with the soot created lethal long-persistence smog: these conditions led to the passing of the UK ’ s " Clean Air Act " which banned the burning of smoke-producing fuel.

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

Visibility in this photo is less than 500 feet ( 150 metres ).

: Visibility less than 100 feet ( 30 meters )

: Visibility 1 / 4 of a mile to 100 feet ( 402 to 30 meters )

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 would sometimes reach 20 feet.

Visibility in this photo is less than 500 feet.

Visibility was about 200 feet at the time of the accident.

* The special issue ( v. 30, no. 5 ) of the journal Environment and Planning-B on Visibility Analysis contains several articles on visibility in urban and natural environments.

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.

* CAVOK is an abbreviation for Ceiling And Visibility OKay, indicating no cloud below or the highest minimum sector altitude and no cumulonimbus or towering cumulus at any level, a visibility of or more and no significant weather.

Visibility is primarily determined by weather conditions ( see visibility ) and by a vehicle's design.

A follow-up e-print by Kastner " On Visibility in the Afshar Experiment " argues that the commonly referenced inverse relationship between visibility parameter V and which-way parameter K does not apply to the Afshar setup, which post-selects for " which slit " after allowing interference to take place.

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.

While " defining visibility using brightness-contrast as the primary variable " in his 1944 book, Light vision and Seeing, Luckiesh presents the ' Visibility Meter ', developed in collaboration with Frank Moss.

Visibility of homosexuals has reached several layers of society that were previously unthinkable, such as the army, Guardia Civil, judges or priests, although in other areas like football there is still a way to go.

Visibility was at its maximum, the sea was placid with a gentle breeze from the north west, a bright, sunny, clear day.

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

* Arc of Visibility: The portion of the horizon over which a lighted aid to navigation is visible from seaward.

The 2012 Class of Inductees are Greg Landry from the “ High Visibility Sports ” and June Olkowski from the “ All Other Sports ” category.

Visibility from a fox hole was practically zero.

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

Visibility graph analysis uses various measures from the theory of small-world networks and centrality in network theory in order to assess perceptual qualities of space and the possible usage of it.

Visibility, like most of Singapore's waters, is chronic, ranging from as low as 0. 1 m to more than 3m.

Visibility is reduced by significant scattering from particles between an observer and a distant object.

Visibility was poor due to bad weather, and French machine gunners in the village of Douaumont thought the Germans were French colonial troops returning from a patrol.

* 25 October 2003 Visibility in the harbour was excellent and winds were between 12 and 15 knots ( 22 to 28 km / h ) from the east.

Visibility was poor because smoke from Canadian forest fires was blowing across Lake Erie.
