Thrust (science fiction magazine)

Thrust was published from 1973–1991. It started off as a Fanzine by Doug Fratz Steven L. Goldstein at the University of Maryland until 1976. In 1978, Thrust became a trade magazine.

Thrust was a magazine for science fiction fans, offering commentary and criticism of work published within the genre. Nominated for a Hugo Award for Best Fanzine in 1980, it received four other nominations for best semi-prozine in the following years (1988, 1989, 1990, and 1991). As a trade magazine, it expanded rapidly, moving to offset covers. Ultimately the circulation rose to 1,700. Columnists at various times included Ted White, Charles Sheffield, Lou Stathis, John Shirley, Michael Bishop, David Bischoff, Chris Lampton, Darrell Schweitzer and Jeffrey Elliot. Dan Steffan provided art direction for the magazine.

Thrust (Transformers)

Thrust is the name of several fictional characters from the Transformers series. The original character was an evil red Decepticon jet, with most of the following character using the name Thrust being a variation on that concept. The biggest exception being the Thrust who appeared in Beast Machines who was an evil Vehicon who turned into a motorcycle.

Transformers: Generation 1

Thrust in the original Transformers toyline is the name of a Decepticon who transforms into a red VTOL jet.

Thrust, Ramjet, and Dirge are part of a team dubbed by Transformers fans as the "Coneheads" for the way their animation models were drawn to make them visually distinct from the original Decepticon jets Starscream, Skywarp, and Thundercracker despite their toys being modifications of the same mold used to create that original trio.

Thrust's personality is that of a braggart who tries to psyche out his opponents with the roar of his engines, but is in fact a coward when it comes to actual battle.

Thrust (video game)

Thrust is a 1986 computer game released on most home computers. The perspective is two dimensional platform-based and the player's aim is to manoeuvre a spaceship by rotating and thrusting, as it flies over a landscape and through caverns. Gameplay of Thrust was heavily inspired by Atari's Gravitar.

Development

The game was programmed by Jeremy Smith (co-author of Exile) and was developed originally on the BBC Micro. Superior Software agreed to publish it as a full price game but they required an Acorn Electron conversion (to release it as a joint BBC/Electron package). While this was being created, it was also ported to other systems beginning with the Commodore 64. All other versions were to be published by Firebird Software at a budget price. The C64 version actually made it to release a couple of months before the BBC/Electron version and became a number one best seller (hence the claim on the BBC/Electron cover).

Gameplay

The aim is to pilot a spacecraft which must pick up a pod using a tractor beam and fly it into space. The ship and pod are subject to gravity and inertia, and being connected by a stiff rod can end up spinning around each other, out of control. Hitting the walls of the cave with either the ship or the pod results in death.

Dimension (data warehouse)

A dimension is a structure that categorizes facts and measures in order to enable users to answer business questions. Commonly used dimensions are people, products, place and time.

In a data warehouse, dimensions provide structured labeling information to otherwise unordered numeric measures. The dimension is a data set composed of individual, non-overlapping data elements. The primary functions of dimensions are threefold: to provide filtering, grouping and labelling.

These functions are often described as "slice and dice". Slicing refers to filtering data. Dicing refers to grouping data. A common data warehouse example involves sales as the measure, with customer and product as dimensions. In each sale a customer buys a product. The data can be sliced by removing all customers except for a group under study, and then diced by grouping by product.

A dimensional data element is similar to a categorical variable in statistics.

Typically dimensions in a data warehouse are organized internally into one or more hierarchies. "Date" is a common dimension, with several possible hierarchies:

Dimension (song)

"Dimension" is a song by Australian hard rock band Wolfmother, featured on their 2005 debut studio album Wolfmother. Written by band members Andrew Stockdale, Chris Ross and Myles Heskett, it was released as the second single from the album in Europe (and the third single overall) on 17 April 2006, charting at number 49 on the UK Singles Chart.

Music video

Directed by The Malloys, the music video for "Dimension" was first aired in the week of 13 February 2006. Prior to this, the video was featured on the 2006 extended play (EP) Dimensions.

Critical reception

In a review of Wolfmother for Blender, writer Jonah Weiner identified "Dimension" as an example of the band "at [their] hardest", describing it as an "acid anthem".NME reviewer James Jam described the song as "a throb of gonzo metal not unlike Black Sabbath playing Motown".

Krull dimension

In commutative algebra, the Krull dimension of a commutative ring R, named after Wolfgang Krull, is the supremum of the lengths of all chains of prime ideals. The Krull dimension need not be finite even for a Noetherian ring. More generally the Krull dimension can be defined for modules over possibly non-commutative rings as the deviation of the poset of submodules.

The Krull dimension has been introduced to provide an algebraic definition of the dimension of an algebraic variety: the dimension of the affine variety defined by an ideal I in a polynomial ring R is the Krull dimension of R/I.

A field k has Krull dimension 0; more generally, k[x₁, ..., x_n] has Krull dimension n. A principal ideal domain that is not a field has Krull dimension 1. A local ring has Krull dimension 0 if and only if every element of its maximal ideal is nilpotent.

Explanation

We say that a chain of prime ideals of the form has length n. That is, the length is the number of strict inclusions, not the number of primes; these differ by 1. We define the Krull dimension of to be the supremum of the lengths of all chains of prime ideals in .
