Tornado (sailboat)

The Tornado is a double handed multihull class recognised as an International Class by the International Sailing Federation. It was used for the Olympic Catamaran discipline for over 30 years.

Background

The boat was designed in 1967 by Rodney March from the Isle of Sheppey, England. At the IYRU Olympic Catamaran Trials for international status, it easily defeated the other challengers.

To increase its performance even further, the Tornado was modified in 2000, with a new sail-plan which included a Spinnaker and Spinnaker boom, as well as an increased sail area of the existing sails. An additional trapeze was also added, and the jib was made self tacking.

The Tornado typically flies one of its two hulls; the crew balancing the boat with their own weight and by controlling the sails. With only one hull in the water, drag is significantly reduced. The Tornado also features an adjustable, rotating mast, which not only greatly improves the aerodynamics of the crucial leading edge of the sail, but also allows improved control over mast bend and thus mainsail flatness. For the high speeds and apparent wind directions seen by this high speed vessel, a flat sail profile is often required.

Sonic the Hedgehog (series)

Sonic the Hedgehog (ソニック・ザ・ヘッジホッグ, Sonikku za Hejjihoggu) is a video game franchise created and owned by Sega. The franchise centers on a series of speed-based platform games, but several are spin-offs in different genres. The protagonist of the series is an anthropomorphic blue hedgehog named Sonic, whose peaceful life is often interrupted by the series's main antagonist, Doctor Eggman. Typically, Sonic—usually along with some of his friends, such as Tails, Amy, and Knuckles—must stop Eggman and foil any plans of world domination. The first game in the series, published in 1991, was conceived by Sega's Sonic Team division after Sega requested a mascot character; the title was a success and spawned sequels, and transformed Sega into a leading video game company during the 16-bit era in the early to mid-1990s.

Sonic Team has since developed many titles in the franchise. Prominent members of its initial staff included Naka, character designer Naoto Ohshima, and level designer Hirokazu Yasuhara. Other developers of Sonic games have included Japanese Dimps, American Sega Technical Institute, Backbone Entertainment, Big Red Button Entertainment, and Sanzaru Games, Canadian BioWare, and British Sumo Digital and Traveller's Tales. While the first games in the series were side-scrolling platform games, the series has expanded into other genres such as action-adventure, fighting, racing, role-playing, and sports. Including packaged game software and downloads, the franchise has sold 335 million units as of April 2015, with the mobile game Sonic Dash being downloaded over 100 million times by June 2015, making it one of the best-selling video game franchises of all time.

Tornado (horse)

Tornado (occasionally Toronado) is a horse ridden by the character Zorro in several movies and books. Tornado is referred to as a black Andalusian in the movie The Mask of Zorro, however in filming a Friesian plays the role. Tornado is said to be very intelligent and very fast. His name is pronounced in the Spanish way, "tor-NAH-do" (except in The Mask of Zorro). Being as jet-black as Zorro's costume enables horse and rider to more easily elude capture at night.

Background

Over the decades and the many stories, the specific details of Tornado's history and personality differ considerably.

In Isabel Allende's novel Zorro, Tornado is given to Don Diego de la Vega upon his return to California, by his milk brother, Bernardo (manservant in the Disney television series), and Bernardo's wife, Light-in-the-night, who trained it. During Bernardo and Diego's Indian initiation ritual before leaving for Spain, Bernardo notices a black foal tentatively following him while he is alone in the woods. Gradually, he befriends the horse, and names him Tornado (pending the horse's approval). He plans to tame Tornado and give him to Diego, but when he wakes up after three days the horse is gone (only to show up again later). Instead of a gift, he takes it as a sign that the horse is his spirit guide, and plans to "develop the horse's virtues: loyalty, strength, and endurance" (76).

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 (metadata)

In metadata, dimension is a set of equivalent units of measure, where equivalence between two units of measure is determined by the existence of a quantity preserving one-to-one correspondence between values measured in one unit of measure and values measured in the other unit of measure, independent of context, and where characterizing operations are the same.

The equivalence defined here forms an equivalence relation on the set of all units of measure. Each equivalence class corresponds to a dimensionality. The units of measure "temperature in degrees Fahrenheit" and "temperature in degrees Celsius" have the same dimensionality, because given a value measured in degrees Fahrenheit there is a value measured in degrees Celsius with the same quantity, and vice versa. Quantity preserving one-to-one correspondences are the well-known equations Cº = (5/9)*(Fº − 32) and Fº = (9/5)*(Cº) + 32.

Units of measure are not limited to physical categories.Examples of physical categories are: linear measure, area, volume, mass, velocity, time duration.Examples of non-physical categories are: currency, quality indicator, colour intensity.

Dimension (shampoo)

Dimension Shampoo was a heavily perfumed shampoo product, which was produced in the early 1980s. This was by the personal products division of Lever Brothers, and marketed by Ogilvy. The shampoo came in a distinctive dark yellow bottle, and left a strong muskone and civetone aroma on the hair. There was also a companion conditioner marketed with this product. It has been stated by many previous users of dimension shampoo that it caused their hair to fall out, due to the extreme astringency of the product.

On April 18, 1985, Lever Brothers reorganized their marketing structure and moved their personal products division business to J. Walter Thompson.

At the time, Dimension was a highly popular brand. (Lever spent an estimated $12.5M in advertising the brand in 1984.) However, shortly after Lever's marketing reorganization, Dimension ran-out on store shelves, and never returned. Lever Brothers never made any public explanation for the disappearance of the product; although they referred to the marketing reorganization as a consolidation of the personal products brands, and stated that the decision in-part had to do with its plans for international marketing.
