Line 19 (Stockholm metro)

Line 19 (T19) is one of the three green lines of the Stockholm Metro connecting Hässelby strand and Hagsätra. It is a 28.6 km (17.8 mi) long line with a 55 min travel time and 35 stations, making it the longest line in the Stockholm Metro.

History

Line 19 was opened as a tramway line in 1930. The line started at Slussen and crossed over the island of Södermalm on existing tramway tracks to Johanneshov from where a new built part continued south towards Stureby and terminated at Örby. In 1933, a tunnel was constructed from Slussen to Skanstull, and operations of line 19, along with tramway line 8, was transferred into the tunnel. This was the first "tunnelbana" (underground railway) in Stockholm, even if it did not have the modern metro standard which is now connected with the term.

In 1950 the line from Slussen to Johanneshov (now Gullmarsplan) was converted from tramway to metro standard. The part of line 19 south of Johanneshov was still serviced by trams until it also was converted in 1951. The new metro line diverted from the original at Stureby and continued to Bandhagen and Högdalen. The stations at the old line, Juliaborg and Örby, were closed, and those areas are since then serviced by busses. In 1957, the line was connected at Slussen to the northern Metro and has since then had its northern terminus at various stations on the line. Southward, the line was extended to Rågsved in 1959 and finally to Hagsätra in 1960.

Floor plan

In architecture and building engineering, a floor plan is a drawing to scale, showing a view from above, of the relationships between rooms, spaces and other physical features at one level of a structure.

Dimensions are usually drawn between the walls to specify room sizes and wall lengths. Floor plans may also include details of fixtures like sinks, water heaters, furnaces, etc. Floor plans may include notes for construction to specify finishes, construction methods, or symbols for electrical items.

It is also called a plan which is a measured plane typically projected at the floor height of 4 ft (1.2 m), as opposed to an elevation which is a measured plane projected from the side of a building, along its height, or a section or cross section where a building, is cut along an axis to reveal the interior structure.

Overview

Similar to a map the orientation of the view is downward from above, but unlike a conventional map, a plan is drawn at a particular vertical position (commonly at about 4 feet above the floor). Objects below this level are seen, objects at this level are shown 'cut' in plan-section, and objects above this vertical position within the structure are omitted or shown dashed. Plan view or planform is defined as a vertical orthographic projection of an object on a horizontal plane, like a map.

Line (poetry)

A line is a unit of language into which a poem or play is divided, which operates on principles which are distinct from and not necessarily coincident with grammatical structures, such as the sentence or clauses in sentences. Although the word for a single poetic line is verse, that term now tends to be used to signify poetic form more generally.

A distinct numbered group of lines in verse is normally called a stanza.

General conventions in Western poetry

A conventions that determine what might constitute line in poetry depend upon different constraints, aural characteristics or scripting conventions for any given language. On the whole, where relevant, a line is generally determined either by units of rhythm or repeating aural patterns in recitation that can also be marked by other features such as rhyme or alliteration, or by patterns of syllable-count.

In Western literary traditions, use of line is arguably the principal feature which distinguishes poetry from prose. Even in poems where formal metre or rhyme is weakly observed or absent, the convention of line continues on the whole to be observed, at least in written representations, although there are exceptions (see Degrees of license). In such writing, simple visual appearance on a page (or any other written layout) remains sufficient to determine poetic line, and this sometimes leads to a "charge" that the work in question is no longer a poem but "chopped up prose". A dropped line is a line broken into two parts, with the second indented to remain visually sequential.

Analog high-definition television system

Analog high-definition television was an analog video broadcast television system developed in the 1930s to replace early experimental systems with as few as 12-lines. On 2 November 1936 the BBC began transmitting the world's first public regular analog high-definition television service from the Victorian Alexandra Palace in north London. It therefore claims to be the birthplace of television broadcasting as we know it today. John Logie Baird, Philo T. Farnsworth, and Vladimir Zworykin had each developed competing TV systems, but resolution was not the issue that separated their substantially different technologies, it was patent interference lawsuits and deployment issues given the tumultuous financial climate of the late '20s and '30s.

Most patents were expiring by the end of World War II leaving no worldwide standard for television. The standards introduced in the early 1950s stayed for over half a century.

UK 405-line system

When the UK introduced 405-line television broadcasting in 1936, it was described as 'high definition television'. By today's standards it most certainly was not even approaching high definition. The description merely referred to its definition in comparison to the early 30-line (largely) experimental system broadcast in the 1920s.
