Structure is an arrangement and organization of interrelated elements in a material object or system, or the object or system so organized. Material structures include man-made objects such as buildings and machines and natural objects such as biological organisms, minerals and chemicals. Abstract structures include data structures in computer science and musical form. Types of structure include a hierarchy (a cascade of one-to-many relationships), a network featuring many-to-many links, or a lattice featuring connections between components that are neighbors in space.
In mathematics, progress often consists of recognising the same structure in different contexts - so that one method exploiting it has multiple applications. In fact this is a normal way of proceeding; in the absence of recognisable structure (which might be hidden) problems tend to fall into the combinatorics classification of matters requiring special arguments.
In category theorystructure is discussed implicitly - as opposed to the explicit discussion typical with the many algebraic structures. Starting with a given class of algebraic structure, such as groups, one can build the category in which the objects are groups and the morphisms are group homomorphisms: that is, of structures on one type, and mappings respecting that structure. Starting with a category C given abstractly, the challenge is to infer what structure it is on the objects that the morphisms 'preserve'.
The term structure was much used in connection with the Bourbaki group's approach. There is even a definition. Structure must definitely include topological space as well as the standard abstract algebra notions. Structure in this sense is probably commensurate with the idea of concrete category that can be presented in a definite way - the topological case means that infinitary operations will be needed. Presentation of a category (analogously to presentation of a group) can in fact be approached in a number of ways, the category structure not being (quite) an algebraic structure in its own right.
Imperial was formed by Dale Dupree, Josh Lightfoot, and Brandon Pangle as "The Red Letter", in Orlando, Florida in 2003. They toured with other bands throughout the United States, ending with a performance at Cornerstone Fest in Illinois.
The tour resulted in a recording contract with Pluto Records. Shortly afterward, the band changed their name from "The Red Letter", due to other bands having similar names, to the name Imperial.
This Grave Is My Poem (2004-2006)
After signing with Pluto Records, the band released their first album, This Grave Is My Poem, with the help of Jeremy Staska at Studio 13 and Allan Douches at West West side for mastering duties.
After this release, they spent the next year touring national with other bands, as well as headlining their own tour. After the tours had completed, they began working on their new album.
Imperial (Cerveza Imperial) is a Costa Rican brand of beer, manufactured by the Florida Ice & Farm Company (FIFCO). Imperial, a lager, was first produced by the Ortega brewery in 1924 and is the most popular beer in Costa Rica. It has spun off Imperial Light and Imperial Silver. FIFCO produces other beers including its Pilsen, Bavaria, and Rock Ice brands.
In addition to being a brand of beer, the term "Imperial" when referring to craft beer is commonly used to describe a brewery's unique take on one of their regular styles. These beers often accentuate the style's characteristics and are labeled as Imperial IPA, Imperial Porter, or Imperial Pilsner, for example.
Its logo, which is a well known icon in Costa Rica, was designed by Enrique Hangen, who, at the time, was the owner of the advertising agency "Casa Gráfica".
Imperial is also known by Costa Ricans as "Aguila" or "Aguilita", which translates into English as "eagle" or "Little Eagle" in reference to its logo, which is the Imperial Eagle used in European heraldry.
