Mesh

A mesh is a barrier made of connected strands of metal, fiber, or other flexible/ductile materials. A mesh is similar to a web or a net in that it has many attached or woven strands.

Types of mesh

Wire

A wire is a single, usually cylindrical, flexible strand or rod of metal. Wires are used to bear mechanical loads or electricity and telecommunications signals. Wire is commonly formed by drawing the metal through a hole in a die or draw plate. Wire gauges come in various standard sizes, as expressed in terms of a gauge number. The term wire is also used more loosely to refer to a bundle of such strands, as in 'multistranded wire', which is more correctly termed a wire rope in mechanics, or a cable in electricity.

Wire comes in solid core, stranded, or braided forms. Although usually circular in cross-section, wire can be made in square, hexagonal, flattened rectangular, or other cross-sections, either for decorative purposes, or for technical purposes such as high-efficiency voice coils in loudspeakers. Edge-woundcoil springs, such as the Slinky toy, are made of special flattened wire.

History

In antiquity, jewelry often contains, in the form of chains and applied decoration, large amounts of wire that is accurately made and which must have been produced by some efficient, if not technically advanced, means. In some cases, strips cut from metal sheet were made into wire by pulling them through perforations in stone beads. This causes the strips to fold round on themselves to form thin tubes. This strip drawing technique was in use in Egypt by the 2nd Dynasty. From the middle of the 2nd millennium BC most of the gold wires in jewellery are characterised by seam lines that follow a spiral path along the wire. Such twisted strips can be converted into solid round wires by rolling them between flat surfaces or the strip wire drawing method. The strip twist wire manufacturing method was superseded by drawing in the ancient Old World sometime between about the 8th and 10th centuries AD. There is some evidence for the use of drawing further East prior to this period.

Wire (Third Day album)

Wire is the seventh album by Christian rock band Third Day. It breaks from the style of the band's previous albums to return to simple, rock and roll-driven melodies. To quote Allmusic's review of the album, "Third Day has stripped away the shine and gotten back to the grittiness of being a rock & roll band." The album is largely carried by the energetic guitar riffs that pervade its songs, although the forceful lyrics also contribute significantly.

The album's songs deal with numerous themes. "Wire", the title track, is a song about the pressure to succeed in modern society. "I Believe", "I Got a Feeling", "Innocent", and other tracks deal with sin, faith, and renewal from a Christian perspective. "Billy Brown" is a catchy song that explores the readiness of people to follow and even idolize entertainment figures.

In November 2004, a live version of Wire was released, called Live Wire featuring a DVD and CD of songs from their tour of their latest album.

The album won 2005 Grammy Award for Best Rock Gospel Album.

Wire (software)

Wire is a communications platform developed for mobile, tablet, and desktop founded by Skype and Microsoft veteran Jonathan Christensen, Alan Duric and Priidu Zilmer. Wire allows users to communicate for free through text, voice, photos, video and music in one interface and across platforms. The app is available on iOS and Android, OS X and Windows.

Wire is headquartered in Switzerland and the development center is in Berlin, Germany.

Founders / History

Wire was founded in Fall 2012 (launched on December 3, 2014) by Jonathan Christensen (CEO), Alan Duric (CTO) and Priidu Zilmer (head of design). Jonathan Christensen previously co-founded Camino Networks in 2005 with Alan Duric, who also co-founded Telio. Camino networks was later acquired by Skype, a division of Microsoft Corporation. At Skype, Jonathan was responsible for getting Skype into new platforms such as Internet televisions and set-top boxes while Priidu Zilmer, former head of design at Vdio, lead the Skype design team.

Partition of an interval

In mathematics, a partition of an interval [a, b] on the real line is a finite sequence x = ( x_i ) of real numbers such that

In other terms, a partition of a compact interval I is a strictly increasing sequence of numbers (belonging to the interval I itself) starting from the initial point of I and arriving at the final point of I.

Every interval of the form [x_i, x_i+1] is referred to as a sub-interval of the partition x.

Refinement of a partition

Another partition of the given interval, Q, is defined as a refinement of the partition, P, when it contains all the points of P and possibly some other points as well; the partition Q is said to be “finer” than P. Given two partitions, P and Q, one can always form their common refinement, denoted P ∨ Q, which consists of all the points of P and Q, re-numbered in order.

Norm of a partition

The norm (or mesh) of the partition

is the length of the longest of these subintervals, that is

Applications

Partitions are used in the theory of the Riemann integral, the Riemann–Stieltjes integral and the regulated integral. Specifically, as finer partitions of a given interval are considered, their mesh approaches zero and the Riemann sum based on a given partition approaches the Riemann integral.

Meš

The cuneiform MEŠ, or meš is a plural form attached at the end of Mesopotamian cuneiform words as a suffix. As part of a name (PN, personal name, or other), or major class being referenced, in capital letters (a sumerogram form), it is typically separated from other capital letter sumerograms with a period. The name of the group can follow, in lower case letters, for example: (men-massu, Amarna letter EA 365), LÚ.MEŠ–ma-as-sà-meš, (and using a secondary suffix meš, not being typical).

The MEŠ cuneiform is a vertical stroke, followed by three or four angled smaller wedge-strokes. The strokes can also be "not angled", but 45 degree wedges, smaller, or large. For example, Amarna letter EA 161, Aziru to Pharaoh, shows a series of six preparation items listed sequentially. The following wedges (on the meš or sumerogram .MEŠ wedges, are large, and the scribe has a scribing base line, that follows the vertical stroke, a baseline on which the wedges are placed sequentially. EA 161 shows the baseline 'remainder', extending beyond the last 3rd, or 4th wedge.
