IBM kept some secrets, as Coppersmith explains: " After discussions with NSA, it was decided that disclosure of the design considerations would reveal the technique of differential cryptanalysis, a powerful technique that could be used against many ciphers.

Feistel networks were first seen commercially in IBM's Lucifer cipher, designed by Horst Feistel and Don Coppersmith in 1973.

The current algorithm with the lowest known exponent k is a generalization of the Coppersmith – Winograd algorithm that has an asymptotic complexity of O ( n < sup > 2. 3727 </ sup >) thanks to Vassilevska Williams .< ref > The original algorithm was presented by Don Coppersmith and Shmuel Winograd in 1990, has an asymptotic complexity of O ( n < sup > 2. 376 </ sup >).</ ref > This algorithm, and the Coppersmith-Winograd algorithm on which it is based, are similar to Strassen's algorithm: a way is devised for multiplying two k × k-matrices with fewer than k < sup > 3 </ sup > multiplications, and this technique is applied recursively.

( 2003, 2005 ) put methods such as the Strassen and Coppersmith – Winograd algorithms in an entirely different group-theoretic context, by utilising triples of subsets of finite groups which satisfy a disjointness property called the triple product property ( TPP ).

The first version was published by Phillip Rogaway and Don Coppersmith in 1994.

It was published in Crypto 1993 by Don Coppersmith, Hugo Krawczyk, and Yishay Mansour.

Gabriel earned a place among the five top ranked competitors ( who are themselves not ranked against each other ) in the William Lowell Putnam Competition all four years that he was eligible ( 2000 – 2003 ), a feat matched by only seven others ( Don Coppersmith ( 1968 – 1971 ), Arthur Rubin ( 1970 – 1973 ), Bjorn Poonen ( 1985 – 1988 ), Ravi Vakil ( 1988 – 1991 ), Reid W. Barton ( 2001 – 2004 ), and Daniel Kane ( 2003 – 2006 ), Bryan R. Lawrence ( 2007 – 08, 2010 – 11 )).

This was indeed the case ; in 1994, Don Coppersmith published some of the original design criteria for the S-boxes.

In 1994, a member of the original IBM DES team, Don Coppersmith, published a paper stating that differential cryptanalysis was known to IBM as early as 1974, and that defending against differential cryptanalysis had been a design goal.

During the 1614 event, whose epicenter was located along the Lajes fault eight kilometers offshore, recorded magnitudes for the earthquake were between 5. 8 and 6. 3 on the Richeter scale ( Wells and Coppersmith, 1994 ).

In linear algebra, the Coppersmith – Winograd algorithm, named after Don Coppersmith and Shmuel Winograd, was the asymptotically fastest known algorithm for square matrix multiplication until 2010.

Coppersmith work started waning in the late 1970s and early 1980s and those in the sheetmetal trade began doing the coppersmith's work, the practices used being similar to those in the plumbing trade.

The Coppersmith – Winograd algorithm is frequently used as a building block in other algorithms to prove theoretical time bounds.

His paper started the search for even faster algorithms such as the more complex Coppersmith – Winograd algorithm published in 1987.

The team at IBM involved in cipher design and analysis included Feistel, Walter Tuchman, Don Coppersmith, Alan Konheim, Carl Meyer, Mike Matyas, Roy Adler, Edna Grossman, Bill Notz, Lynn Smith, and Bryant Tuckerman.

This differs from the aggregate decision making of classical political economy in that it explains how vital goods such as water can be cheap, while luxuries can be expensive.

In decision making, satisficing explains the tendency to select the first option that meets a given need or select the option that seems to address most needs rather than the “ optimal ” solution.

For example, the recognition primed decision ( RPD ) model explains how people can make relatively fast decisions without having to compare options.

Although the award is generally spoken of the " best and fairest ", the award's specific criterion is " fairest and best ", reflecting an emphasis on sportsmanship and fair play ( which also explains the decision to have the votes cast by the umpires ), as the 1924 somewhat illuminated citation expressly states:

" He explains himself in Concluding Unscientific Postscript, where he writes, “ In that book and Trembling I had perceived how the leap, according to the author, as the decision par excellence becomes specifically decisive for what is Christian and for every dogmatic category.

Kraven then explains that when Dr. Crawford contracted an African plague, he makes the decision to save her life by giving her a dose of the same miracle-drug that had caused his transformation.

* Author, decides based on what they as a player want for their character and then retroactively explains why their character made that decision

The committee also submits a written report that explains the background for its decision, analyzes the purposes and effects of each major provision of the bill, and includes other information, such as predictions about the cost of implementing it, that help other Members decide whether they should support the bill.

From then on, monarchs could not ignore them, which explains Henry's decision to summon the Commons to several of his post-1265 parliaments.

Frey also explains: “ The whole pattern of this final soliloquy is thus a grim parody of the opening one, where decision is reached after, not prior to, the survey ”.

As philosopher David Benatar explains, at the heart of the decision to bring a child into the world often lies the parents ' own desires ( to enjoy child-rearing or perpetuate one's legacy / genes ), rather than the potential person's interests.

At the airport, she explains her decision to her brother Gary ( Kevin Kilner ), and she melodramatically rips up the bill in front of him.

It was Queen Victoria ’ s Diamond Jubilee year, when pomp and ceremony might have been given free rein and thus to some degree explains the decision to erect such a worthy monument, and even given that the Queen herself had sent some £ 35 /~ into the fund goes no way at all in justifying the rational in depriving the boatmen ’ s families of their wishes.

" violated the terms of our agreement in ways that substantially and negatively impacted September 24 ’ s message and impact ," remarks that " co-sponsorship with ANSWER on September 24 was welcomed by some in the antiwar movement but limited or prevented completely the participation of others ," and explains, " We did not have consensus " about the decision not to work with A. N. S. W. E. R., but had " a more than two thirds supermajority … We make no recommendations or mandates on this issue to UFPJ member groups in local or constituency-based area …"

On 29 October 2011, David Morgan-Mar posted a message with a strip displaying a large sign reading " The End ", in which he explains his decision to discontinue the creation of new strips.

The Tour's paperwork vanished when it was taken south from Paris in 1940 to escape the German invasion of the second world war and none of the newspaper reports of the period explains Bottecchia's decision.

Here at least explains, from the Classical viewpoint, its approximate method with a large amount of traditional rationality for its oeuvre heavily reliant on tradition to make conclusions ' as final decisions ' towards conclusions. Foucault uses a rather unusual method involving oeuvre de la obscure meaning the ' obscure ' is seen as the building block for human rationality functioning as norms which become familiar to people, giving the uninformed their ' view ' and ' truth ' of the world. The uninformed means the uninformed who have no direct access to policy decision making therefore condemning those who work into a continuous comatose ignorance producing this network of power systems creating what Marx called ' labour power ' which recreate and recycle a functioning society ( comparable to a living breathing organism ) and the population of producers who have no monetary resources and ownership of capital wealth ; ownership of mines, banks, transportation equipment and machinery, such as aeroplanes car manufacturers and industry and therefore are confined to the bottom of the hiercharchical pyramid, producing the problematization of a society comparable to Ants or Bees which inform evolutionary biology, for example of human nature. While inaccurate and now known to be scientifically flawed, nevertheless it remains ' true ' from the classical perspective as opposed to the working population who are not uneducated or illiterate a wall which can be pieced.

A " judicial opinion " or " opinion of the court " is an opinion of a judge or group of judges that accompanies and explains an order or ruling in a controversy before the court, laying out the rationale and legal principles the court relied on in reaching its decision.

Firstly, she explains, " contrary to the general opinion, the Comcast decision does not uproot the Commission's authority to regulate ISPs.

McCullough explains that, while it is certainly known Sulla's first wife was a Julia, it is not known to which branch of the Julii she belonged, but she was certainly a relation of Marius's better-known Julian wife, hence the decision to assign her the role in the novel of a younger sister.

This decision explains Soul Reavers cliffhanger ending and the appearance of originally planned material in later games.

Mrs. Warren explains her impoverished past and decision to be a prostitute at last to her daughter, but hides the fact rhat she is still in the business.
