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 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 vary rapidly ; in only a few feet visibility can go from 10 feet to near zero.

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

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

Visibility may be reduced to 50 metres for days at a time.

The DRX Army Soldiers were defending CHOI with pacific acts and with a huge " Visibility Operation ", which caused the whole area of Quebec and its surroundings to be marked with " DRX Army " and " Liberté!

Aircraft and vehicles are not allowed in this area when Low Visibility Procedures are in force, since aircraft will be making autolands and therefore the accuracy of the guidance signals provided by the ILS is absolutely critical.

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 was poor and he mistook the peaks of Taveuni to be separate islands.

Visibility was limited by rain, and Australian casualties soon began to mount.

Visibility was so limited that streetlights remained lit throughout the day and motorists needed their headlights to navigate city streets.

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 ).

In late 1984, the BN commenced the High Visibility study which applied orange and black nose stripes and orange along the cab face on one locomotive followed by two new orders of locomotives: EMD SD40-2, EMD GP50, and EMD SD60 respectively.

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

Visibility degradation is caused by the absorption and scattering of light by particles and gases in the atmosphere.

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

* In 2000, the Art Gallery Society supported the purchase of drawings Visibility / Invisibility by Jennifer Keeler-Milne and Urban landscape II by Sallie Moffat.

Visibility remained poor in Rabaul town ( 3 – 5 km NW of Tavurvur ) due to ash made airborne by the passage of moving vehicles.

* Visibility Plan ( data plan with voice for postpaid and prepaid ) currently discontinued, replaced by Globe Tattoo.

Visibility for the driver was improved by the provision of wrap-around cab windows.

Visibility in foggy conditions was one of the factors for the development of this type of signal.

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 was good at the time, but with a Spring tide ebbing to the west and a westerly Force 5 wind, the sea conditions near Corbière were moderate to rough.

* 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.

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

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.

* Visibility of the road.

Visibility of the bicycle.

Visibility in traffic is much debated.

Visibility concerns become minimal on bike trails and off-street riding.

* 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.

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

Visibility was no more than.

Since then, features of HV clothing such as the EN510 quick release standard and the EN471 High Visibility standard, have improved the effectiveness and contributed to improved safety for rail workers.

The International High Visibility Clothing Association found numerous flaws with the prevailing EN471: 2003 and ANSI / ISEA 107-2010 standards.

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