Box crib

A box crib or cribbing is a temporary wooden structure used to support heavy objects during construction, relocation, vehicle extrication and urban search and rescue. It is commonly used to secure overturned motor vehicles, and debris within collapsed buildings. Cribbing is often used in conjunction with other stabilization equipment, such as pneumatic or hydraulic shoring. Cribbing is also used in sub-surface mining as a roof support. Cribbing has largely been replaced by hydraulic shoring in modern mining applications.

Some forms of cribbing can also be used on movie sets and production sites for stabilizing dolly tracks, platforms, and various temporary structures when quick setup times are needed.

Stability

The stability of a crib is affected by a variety of factors: the material used (often a soft wood which gives audible warnings before failure), the number of contact points between the crib and the supported surface, the ratio of the footprint of the crib to its height, and the area of contact made between the crib and the ground and supported surface.

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.

Hi-Riser (automobile)

Hi-Risers are a type of highly customized automobile, typically a traditional, full-size, body on frame, V8 powered, rear wheel drive American-built sedan modified by significantly increasing the ground clearance and adding large-diameter wheels with low-profile tires. Depending on the model and style of body, autos customized in this manner can be labeled "donk," "box," or "bubble."

Hi-risers originally grew out of the Dirty South subculture, but the trend has spread across the United States. Vehicles customized in the hi-riser style are distinguished by their oversized (even disproportionate) wheels, ranging from 20 inches to 30 inches or more in diameter (largest being 50 inch), as well as fanciful custom paint-jobs and expensive audio equipment. Suspension modifications similar to those employed on lifted pickup trucks are made to give adequate clearance for the large wheels. Often the suspension is modified so the front end sits slightly higher than the rear end, giving the car a swaggering appearance. Because of the exaggerated look gained from installing a lifted suspension and enormous wheels, donks are also known as "hi-risers" or "sky-scrapers."

Hyperrectangle

In geometry, an n-orthotope (also called a hyperrectangle or a box) is the generalization of a rectangle for higher dimensions, formally defined as the Cartesian product of intervals.

Types

A three-dimensional orthotope is also called a right rectangular prism, rectangular cuboid, or rectangular parallelepiped.

A special case of an n-orthotope, where all edges are equal length, is the n-cube.

By analogy, the term "hyperrectangle" or "box" refers to Cartesian products of orthogonal intervals of other kinds, such as ranges of keys in database theory or ranges of integers, rather than real numbers.

Dual polytope

The dual polytope of an n-orthotope has been variously called a rectangular n-orthoplex, rhombic n-fusil, or n-lozenge. It is constructed by 2n points located in the center of the orthotope rectangular faces.

An n-fusil's Schläfli symbol can be represented by a sum of n orthogonal line segments: { } + { } + ... + { }.

A 1-fusil is a line segment. A 2-fusil is a rhombus. Its plane cross selections in all pairs of axes are rhombi.

Crib

A crib is an infant bed in American English (British English: cot).

Bach (New Zealand)

A bach (pronounced 'batch') (/ˈbætʃ/; (also called a crib in the southern half of the South Island) is a small, often very modest holiday home or beach house. Baches are an iconic part of New Zealand history and culture, especially in the middle of the 20th century, where they symbolized the beach holiday lifestyle that was becoming more accessible to the middle class.

"Bach" was [thought to be] originally short for bachelor pad, but actually they often tended to be a family holiday home. An alternative theory for the origination of the word is that bach is Welsh for small, although the pronunciation of this word is somewhat different. Baches began to gain popularity in the 1950s as roads improved and the increasing availability of cars allowed for middle-class beach holidays, often to the same beach every year. With yearly return trips being made, baches began to spring up in many family vacation spots.

Construction

Post-World War II

They are almost always small structures, usually made of cheap or recycled material like fibrolite (asbestos sheets), corrugated iron or used timber. They were influenced by the backwoods cabins and sheds of the early settlers and farmers. Other baches used a caravan as the core of the structure, and built extensions on to that. Many cities were dismantling tram lines in the 1950s, and old trams were sometimes used as baches.

Known-plaintext attack

The known-plaintext attack (KPA) is an attack model for cryptanalysis where the attacker has access to both the plaintext (called a crib), and its encrypted version (ciphertext). These can be used to reveal further secret information such as secret keys and code books. The term "crib" originated at Bletchley Park, the British World War II decryption operation.

History

The usage "crib" was adapted from a slang term referring to cheating (e.g., "I cribbed my answer from your test paper.") A "crib" originally was a literal or interlinear translation of a foreign-language text — usually a Latin or Greek text — that students might be assigned to translate from the original language.

The idea behind a crib is that cryptologists were looking at incomprehensible ciphertext, but if they had a clue about some word or phrase that might be expected to be in the ciphertext, they would have a "wedge," a test to break into it. If their otherwise random attacks on the cipher managed to sometimes produce those words or (preferably) phrases, they would know they might be on the right track. When those words or phrases appeared, they would feed the settings they had used to reveal them back into the whole encrypted message to good effect.
