Confusion

Confusion (from Latin confusĭo, -ōnis, from confundere: "to pour together;" "to mingle together;" "to confuse") is the state of being bewildered or unclear in one’s mind about something.

Medical term

The term, "acute mental confusion" is often used interchangeably with delirium in the International Statistical Classification of Diseases and Related Health Problems and the Medical Subject Headings publications to describe the pathology. These refer to the loss of orientation, or the ability to place oneself correctly in the world by time, location; and personal identity. Mental confusion is sometimes accompanied by disordered consciousness (the loss of linear thinking) and memory loss (the ability to correctly recall previous events or learn new material).

Causes

Confusion may result from drug side effects or from a relatively sudden brain dysfunction. Acute confusion is often called delirium (or "acute confusional state"), although delirium often includes a much broader array of disorders than simple confusion. These disorders include the inability to focus attention; various impairments in awareness; and temporal or spatial dis-orientation. Mental confusion can result from chronic organic brain pathologies, such as dementia, as well.

Confusion (disambiguation)

Mental confusion is the inability to think clearly and quickly.

Phelix

Phelix is a high-speed stream cipher with a built-in single-pass message authentication code (MAC) functionality, submitted in 2004 to the eSTREAM contest by Doug Whiting, Bruce Schneier, Stefan Lucks, and Frédéric Muller. The cipher uses only the operations of addition modulo 2³², exclusive or, and rotation by a fixed number of bits. Phelix uses a 256-bit key and a 128-bit nonce, claiming a design strength of 128 bits. Concerns have been raised over the ability to recover the secret key if the cipher is used incorrectly.

Performance

Phelix is optimised for 32-bit platforms. The authors state that it can achieve up to eight cycles per byte on modern x86-based processors.

FPGA Hardware performance figures published in the paper "Review of stream cipher candidates from a low resource hardware perspective" are as follows:

Helix

Phelix is a slightly modified form of an earlier cipher, Helix, published in 2003 by Niels Ferguson, Doug Whiting, Bruce Schneier, John Kelsey, Stefan Lucks, and Tadayoshi Kohno; Phelix adds 128 bits to the internal state.

Helix (multimedia project)

Helix DNA is a project to produce computer software that can play audio and video media in various formats, aid in producing such media, and serve them over a network. It is intended as a largely free and open source digital media framework that runs on numerous operating systems and processors (including mobile phones) and was started by RealNetworks which contributed much of the code. The Helix Community is an open collaborative effort to develop and extend the Helix DNA platform.

Helix DNA Client is a software package for multi-platform multi-format media playback. Helix Player is a media player that runs on Linux, Solaris, Symbian and FreeBSD and uses the Helix DNA Client. The Helix DNA Producer application aids in the production of media files, and Helix DNA Server can stream media files over a network.

Licenses

The code is released in binary and source code form under various licenses, notably the proprietary RealNetworks Community Source License and the free and open source software RealNetworks Public Source License. Additionally, the Helix DNA Client and the Helix Player are licensed under the popular GNU General Public License (GPL) free and open source license.

Helix (company)

Helix is a family-run United Kingdom-based manufacturer of scholastic stationery. It currently employs 75 people, and exports to over 65 countries, with offices in Chicago and Hong Kong and with UK headquarters based in Lye, West Midlands.

History

Helix was established in 1887, under the name The Universal Woodworking Company Ltd., manufacturing wooden rules and metal laboratory apparatus.In 1894 it patented the drawing compass, and with it, launched the Helix brand, following on from the initial success of the compass and rule, in 1912 the company's first mathematical set was created and in 1935 the brand "Helix Oxford" was launched. 1955 saw the company become known as the Helix Universal Company, moving its headquarters to Lye, where it is still based today. In the 1960s the name again changed to its current name Helix International Ltd.. Helix is now part of the French owned Maped group.
