Core (functional analysis)

In functional analysis, a discipline within mathematics, a core may be:

Lithic core

In archaeology, a lithic core is a distinctive artifact that results from the practice of lithic reduction. In this sense, a core is the scarred nucleus resulting from the detachment of one or more flakes from a lump of source material or tool stone, usually by using a hard hammer percussor such as a hammerstone. The core is marked with the negative scars of these flakes. The surface area of the core which received the blows necessary for detaching the flakes is referred to as the striking platform. The core may be discarded or shaped further into a core tool, such as can be seen in some types of handaxe.

The purpose of lithic reduction may be to rough out a blank for later refinement into a projectile point, knife, or other stone tool, or it may be performed in order to obtain sharp flakes, from which a variety of simple tools can be made. Generally, the presence of a core is indicative of the latter process, since the former process usually leaves no core. Because the morphology of cores will influence the shape of flakes, by studying the core surface morphology, we might be able to know more information about the dimensional flake attribute, including their length and thickness. Cores may be subdivided into specific types by a lithic analyst. Type frequencies, as well as the general types of materials at an archaeological site, can give the lithic analyst a better understanding of the lithic reduction processes occurring at that site.

Intel Core 2

Core 2 is a brand encompassing a range of Intel's consumer 64-bit x86-64 single-, dual-, and quad-core microprocessors based on the Core microarchitecture. The single- and dual-core models are single-die, whereas the quad-core models comprise two dies, each containing two cores, packaged in a multi-chip module. The introduction of Core 2 relegated the Pentium brand to the mid-range market, and reunified laptop and desktop CPU lines, which previously had been divided into the Pentium 4, Pentium D, and Pentium M brands.

The Core 2 brand was introduced on 27 July 2006, comprising the Solo (single-core), Duo (dual-core), Quad (quad-core), and in 2007, the Extreme (dual- or quad-core CPUs for enthusiasts) subbrands. Intel Core 2 processors with vPro technology (designed for businesses) include the dual-core and quad-core branches.

Models

The Core 2-branded CPUs include: "Conroe"/"Allendale" (dual-core for desktops), "Merom" (dual-core for laptops), "Merom-L" (single-core for laptops), "Kentsfield" (quad-core for desktops), and the updated variants named "Wolfdale" (dual-core for desktops), "Penryn" (dual-core for laptops), and "Yorkfield" (quad-core for desktops). (Note: For the server and workstation "Woodcrest", "Tigerton", "Harpertown" and "Dunnington" CPUs see the Xeon brand.)

Free (The Party album)

Free is The Party's second studio album. Teddy Riley wrote three songs for the album, including the new jack swing-tinged title song, "Free," which was also remixed by house-music legends Steve "Silk" Hurley and E-Smoove. Dr. Dre produced the song "Let's Get Right Down to It," and the group itself also got involved in the writing and producing of the album, which would once again land it another concert tour opening spot with Color Me Badd, its last special for the Disney Channel, "All About The Party," and an appearance on Blossom. However, the album was not as successful on the charts as previous ones, which prompted Damon Pampolina to leave the group.

Free: The Future of a Radical Price

Free: The Future of a Radical Price is the second book written by Chris Anderson, Editor in chief of Wired magazine. The book was published on July 7, 2009 by Hyperion. He is also the author of The Long Tail, published in 2006.

Overview

Free follows a thread from the previous work. It examines the rise of pricing models which give products and services to customers for free, often as a strategy for attracting users and up-selling some of them to a premium level. That class of model has become widely referred to as "freemium" and has become very popular for a variety of digital products and services.

Release

Free was released in the United States on July 7, 2009, though the night before, on his blog, Chris Anderson posted a browser readable version of the book and the unabridged audiobook version. Anderson generated controversy for plagiarizing content from the online encyclopedia Wikipedia in Free. Anderson responded to the claim on his The Long Tail blog, stating that there were disagreements between him and the publisher over accurate citation of Wikipedia due to the changing nature of its content, leading him to integrate footnotes into the text. Also on his blog, he took full responsibility for the mistakes and noted that the digital editions of Free were corrected. The notes and sources were later provided as a download on his blog.

Free (Marcus Miller album)

Free is an album by jazz bassist Marcus Miller, released in 2007.

The album's title track is a cover of the 1977 Deniece Williams song. UK soul singer Corinne Bailey Rae provided lead vocals. "Higher Ground" is a song originally recorded by Stevie Wonder, and "What Is Hip" was originally performed by Tower of Power. "Jean Pierre" was originally performed by Miles Davis (On "We Want Miles", 1982). Blues singer Keb' Mo' performs lead vocals and co-wrote with Marcus Miller the track entitled "Milky Way".

The album's US version has not only a new title, Marcus, but the tracks have been remixed/recut. Four additional tracks have been added to the album as well.
