John Harrison, a self-educated English clockmaker then invented the marine chronometer, a key piece in solving the problem of accurately establishing longitude at sea, thus revolutionising and extending the possibility of safe long distance sea travel.

What's most impressive about that gift -- focused as it may be by the intensified concentration that his dyslexia demands -- is Boies ' uncanny ability to recall a key fact, legal citation or piece of contradictory testimony at moments of the most intense pressure.

The key piece of surviving written evidence is a letter Anne wrote sometime in 1514.

This system of accidentals operates in conjunction with the key signature, whose effect continues throughout an entire piece, unless canceled by another key signature.

* Name the key of a given piece of tonal music just by listening ( without reference to an external tone )

During the proceedings, a fortune cookie was introduced as a key piece of evidence with a message reading, " S. F.

In cryptography, a key is a piece of information ( a parameter ) that determines the functional output of a cryptographic algorithm or cipher.

A key is often easier to protect ( it's typically a small piece of information ) than an encryption algorithm, and easier to change if compromised.

The sound on each individual tape piece was recorded at the pitch of the key to which it was assigned.

The Pacers acquired another key piece in Leandro Barbosa from the Toronto Raptors at the trade deadline, mid-season.

Finally, both Thrawn's and Karrde's ability to piece together far-reaching ( and accurate ) conclusions from the merest shreds of evidence, thus increasing the value of that evidence, mirrored the real-world advent of the Information Age and its emphasis on knowledge as a key military asset.

This key is maintained to the end of the piece.

The piece is divided into four sections, each marked by a key change initiated by the metallophone.

The singers ' normal use of the pipe is to play the initial key note or tonic of the piece to be sung.

Paul Driver comments enthusiastically on the Colin Davis and London Symphony Orchestra performance of the Inextinguishable in May 2010: " Movement boundaries have become fluid ; the expressive raison d ’ être is an evolving structure articulated by its emotional necessities rather than an externally valid architecture ; and the journey from harmonic ambiguity at the opening to a stable key at the end is no mere vehicle for carrying ideas, but the whole point of the piece.

The second section of the piece begins in the newly established key, where it remains for an indefinite period of time.

The design and strength of all key lengths of the AES algorithm ( i. e., 128, 192 and 256 ) are sufficient to protect classified information up to the SECRET level.

TOP SECRET information will require use of either the 192 or 256 key lengths.

A key characteristic of bandwidth is that a band of a given width can carry the same amount of information, regardless of where that band is located in the frequency spectrum.

Shannon's work on information theory showed that to achieve so called perfect secrecy, it is necessary for the key length to be at least as large as the message to be transmitted and only used once ( this algorithm is called the One-time pad ).

See the discussion on the relationship between key lengths and quantum computing attacks at the bottom of this page for more information.

Records of births, deaths, marriages, immigration and emigration and a regular census of population provide information that is key to making sound decisions about national policy.

Linking the information back together is the key to this system.

In the relational model, some bit of information was used as a " key ", uniquely defining a particular record.

When information was being collected about a user, information stored in the optional tables would be found by searching for this key.

The idea was to replicate specific important, and often queried information, and store it in a smaller temporary database that linked these key features back to the main database.

As with other wavelet transforms, a key advantage it has over Fourier transforms is temporal resolution: it captures both frequency and location information ( location in time ).

In cryptography, encryption is the process of transforming information ( referred to as plaintext ) using an algorithm ( called a cipher ) to make it unreadable to anyone except those possessing special knowledge, usually referred to as a key.

Hayek is widely recognized for having introduced the time dimension to the equilibrium construction and for his key role in helping inspire the fields of growth theory, information economics, and the theory of spontaneous order.

The derivation outlined in the previous section contains all the information needed to define general relativity, describe its key properties, and address a question of crucial importance in physics, namely how the theory can be used for model-building.

The key points within this ethic are access, freedom of information, and improvement to quality of life.

The hedge fund's prospectus, also known as an offering memorandum, offers potential investors information about key aspects of the fund, including the fund's investment strategy, investment type, and leverage limit.

* The ICT Security Standards Roadmap has been developed to assist in the development of security standards by bringing together information about existing standards and current standards work in key standards development organizations.

A key measure of information is known as entropy, which is usually expressed by the average number of bits needed to store or communicate one symbol in a message.

In such cases, the positive conditional mutual information between the plaintext and ciphertext ( conditioned on the key ) can ensure proper transmission, while the unconditional mutual information between the plaintext and ciphertext remains zero, resulting in absolutely secure communications.

It carries all the routing information needed to get a payment from one bank to another wherever it may be ; it contains all the key bank account details such as Bank Identifier Codes, branch codes ( known as sort codes in the UK and Ireland ) and account numbers and it contains check digits which can be validated at source according to a single standard procedure.

In most countries, trading by corporate insiders such as officers, key employees, directors, and large shareholders may be legal, if this trading is done in a way that does not take advantage of non-public information.
