ARC (file format)

ARC is a lossless data compression and archival format by System Enhancement Associates (SEA). It was very popular during the early days of networked dial-up BBS. The file format and the program were both called ARC. The ARC program made obsolete the previous use of a combination of the SQ program to compress files and the LU program to create .LBR archives, by combining both compression and archiving functions into a single program. Unlike ZIP, ARC is incapable of compressing entire directory trees. The format was subject to controversy in the 1980s—an important event in debates over what would later be known as open formats.

The .arc file extension is often used for several file archive-like file types. For example, the Internet Archive uses its own ARC format to store multiple web resources into a single file. The FreeArc archiver also uses .arc extension, but uses a completely different file format.

Nintendo uses an unrelated 'ARC' format for resources, such as MIDI, voice samples, or text, in GameCube and Wii games. Several unofficial extractors exist for this type of ARC file.

Arc (projective geometry)

A (simple) arc in finite projective geometry is a set of points which satisfies, in an intuitive way, a feature of curved figures in continuous geometries. Loosely speaking, they are sets of points that are far from "line-like" in a plane or far from "plane-like" in a three-dimensional space. In this finite setting it is typical to include the number of points in the set in the name, so these simple arcs are called k-arcs. An important generalization of the k-arc concept, also referred to as arcs in the literature, are the (k, d)-arcs.

k-arcs in a projective plane

In a finite projective plane π (not necessarily Desarguesian) a set A of k (k ≥ 3) points such that no three points of A are collinear (on a line) is called a k - arc. If the plane π has order q then k ≤ q + 2, however the maximum value of k can only be achieved if q is even. In a plane of order q, a (q + 1)-arc is called an oval and, if q is even, a (q + 2)-arc is called a hyperoval.

Every conic in the Desarguesian projective plane PG(2,q), i.e., the set of zeros of an irreducible homogeneous quadratic equation, is an oval. A celebrated result of Beniamino Segre states that when q is odd, every (q + 1)-arc in PG(2,q) is a conic. This is one of the pioneering results in finite geometry.

Directed graph

In mathematics, and more specifically in graph theory, a directed graph (or digraph) is a graph, or set of vertices connected by edges, where the edges have a direction associated with them. In formal terms, a directed graph is an ordered pair G = (V, A) (sometimes G = (V, E)) where

It differs from an ordinary or undirected graph, in that the latter is defined in terms of unordered pairs of vertices, which are usually called edges, arcs, or lines.

A directed graph is called a simple digraph if it has no multiple arrows (two or more edges that connect the same two vertices in the same direction) and no loops (edges that connect vertices to themselves). A directed graph is called a directed multigraph or multidigraph if it may have multiple arrows (and sometimes loops). In the latter case the arrow set forms a multiset, rather than a set, of ordered pairs of vertices.

Klinik

Klinik, (sometimes called The Klinik), is an industrial music band from Belgium, originally formed around 1982 by electro-synthpop practitioner Marc Verhaeghen, who is the only constant member.

History

Marc Verhaeghen originally formed Klinik in the early-to-mid 1980s; the exact date varies depending on the source. The group is normally described as one of the most influential Belgian industrial bands in history.

In 1985, Verhaeghen joined forces with two other bands, Absolute Body Control (with Dirk Ivens and Eric van Wonterghem), and "The Maniacs" (Sandy Nys) to form one "super group" "Absolute Controlled Clinical Maniacs". This rather unwieldy name was soon dropped in favour of the shorter name "The Klinik". Nys soon left the band to form "Hybryds", followed in 1987 by van Wonterghem, leaving The Klinik as the "classic" duo of Dirk Ivens and Marc Verhaeghen.

The Klinik soon made a name for themselves with their cold and harsh EBM sound and their live shows, where both Ivens and Verhaeghen performed with their heads wrapped in gauze, wearing long black leather coats. Ivens' hissing vocals and minimalist lyrics were complemented by Verhaeghen's synthesizer skills and distorted trombone playing. This however, did not last forever; after Time, an album neither member was fully pleased with, musical differences became too great, and they decided to go their separate ways. In a 2013 interview, Ivens said the due were moving in different directions musically, and that compromise between only two members was challenging.

Emi Maria

Emi Maria, stylized as EMI MARIA, (born June 9, 1987) is a Japanese Papua New Guinean R&B singer-songwriter. She debuted in 2007 with the EP Between the Music.

Biography

Emi Maria was born in 1987 in Papua New Guinea. Her father is Papua New Guinean, while her mother is Japanese. She spent the first five years of her life in Papua New Guinea, before moving to Kobe in Japan.

She first started listening to R&B at 6 due to her sister, listening to such artists as Janet and Michael Jackson, and K-Ci & JoJo. She began writing lyrics in junior high school. By high school, she had started writing music and producing her own tracks. She participated in the MTV Star Tour, and started performing lives in the Kansai area from 2006 onwards. In 2007, she started appearing on many different Japanese urban artists' albums as a guest artist, such as Seeda and MC Moggy.

In 2007, Emi Maria released her first EP, Between the Music on Freest Inc., a label she had created for herself. Her debut single "I Gotta (Summer Kiss)" was picked as the iTunes Japan single of the week in August 2008.
