Close (surname)

Close is a surname, and may refer to:

Cul-de-sac

A cul-de-sac /ˈkʌldəsæk/, dead end (British, Canadian, American, South African English, and Australian English), closed, no through road, a close (British, Canadian, and Australian English), no exit (New Zealand English) or court (American, Australian English) is a street with only one inlet/outlet. While historically built for other reasons, one of its modern uses is to calm vehicle traffic.

History

Culs-de-sac have appeared in plans of towns and cities before the automotive 20th century, particularly in Arab and Moorish towns. The earliest example of cul-de-sac streets was unearthed in the El-Lahun workers village in Egypt, which was built circa 1885 BC. The village is laid out with straight streets that intersect at right angles; akin to a grid, but irregular. The western part of the excavated village, where the workers lived, shows fifteen narrow and short dead-end streets laid out perpendicularly on either side of a wider, straight street; all terminate at the enclosing walls.

Eye

Eyes are the organs of vision. They detect light and convert it into electro-chemical impulses in neurons. In higher organisms, the eye is a complex optical system which collects light from the surrounding environment, regulates its intensity through a diaphragm, focuses it through an adjustable assembly of lenses to form an image, converts this image into a set of electrical signals, and transmits these signals to the brain through complex neural pathways that connect the eye via the optic nerve to the visual cortex and other areas of the brain. Eyes with resolving power have come in ten fundamentally different forms, and 96% of animal species possess a complex optical system. Image-resolving eyes are present in molluscs, chordates and arthropods.

The simplest "eyes", such as those in microorganisms, do nothing but detect whether the surroundings are light or dark, which is sufficient for the entrainment of circadian rhythms. From more complex eyes, retinal photosensitive ganglion cells send signals along the retinohypothalamic tract to the suprachiasmatic nuclei to effect circadian adjustment and to the pretectal area to control the pupillary light reflex.

Eyes (TV series)

Eyes is an ABC television series starring Tim Daly as Harlan Judd. Eyes follows the firm of Judd Risk Management which uses marginally legal means to investigate individuals and crimes where law enforcement would fall short. With the help of high-tech gadgets, Harlan Judd and his employees recover money for victims as well as investigate individuals for clients but still manage to keep plenty of secrets from one another.

In May 2005, having rescheduled the sixth episode twice, ABC announced that they would not be airing the remaining episodes until June at the earliest. They later announced that it would not be picked up for a second season and that the remaining episodes would remain unaired.

New Zealand television station TV2 picked up this show and aired the complete series, all twelve episodes, in the second half of 2005. These episodes appeared online via BitTorrent soon after. The show was also partially aired on Singapore television station Mediacorp Channel 5, with the pilot episode and episodes #106 to #112 being skipped. Episode #111 ("Burglary") was an exception, and was aired as the fifth episode. The show was also aired in full on France cable television station Canal Jimmy in 2006. In the beginning of 2008 the show was aired in full on Polish television station TVN 7. The series was shown on the Nine Network in Australia in 2007.

Eyes (video game)

Eyes is an arcade game released in 1982 by Rock-Ola.

Gameplay

The player controls a hat-wearing eyeball in a maze. As in Pac-Man the goal is to collect all of the dots to advance to next level, but in Eyes you shoot the dots rather than eat them. Computer-controlled eyes chase and shoot at the player. Shooting a computer eye gives points and removes it from the level, but it will reappear a short time later. Being shot by a computer eye is fatal.

As the game progresses, more computer eyes are added to levels and they take less time to shoot at the player. They also move faster.

USGS DEM

The USGS DEM standard is a geospatial file format developed by the United States Geological Survey for storing a raster-based digital elevation model. It is an open standard, and is used throughout the world. It has been superseded by the USGS's own SDTS format but the format remains popular due to large numbers of legacy files, self-containment, relatively simple field structure and broad, mature software support.

DEM Level

A USGS DEM can be classified into one of four levels of quality. This is due to the multiple methods of data collection, and certainty in the data.

Format Structure

The USGS DEM format is a self-contained (single file) set of ASCII-encoded (text) 1024-byte (1024 ASCII chars) blocks that fall into three record categories called A, B, and C. There is no cross-platform ambiguity since line ending control codes are not used, and all data including numbers is represented in readable text form. There is no known binary analogue of the format, although it is common practice to compress the files with gzip.

DEM (disambiguation)

DEM was the ISO 4217 currency code for the Deutsche Mark, former currency of Germany.
