Disambiguation Dos And Don'ts
Word-sense disambiguation (WSD) is the process of identifying which word sense, sense of a word is meant in a sentence (linguistics), sentence or other segment of context (language use), context. In human language processing in the brain, language processing and cognition, it is usually subconscious/automatic but can often come to consciousness, conscious attention when ambiguity impairs clarity of communication, given the pervasive polysemy in natural language. In computational linguistics, it is an open problem that affects other computer-related writing, such as discourse, improving relevance of search engines, anaphora resolution, coherence (linguistics), coherence, and inference. Given that natural language requires reflection of neurological reality, as shaped by the abilities provided by the brain's biological neural network, neural networks, computer science has had a long-term challenge in developing the ability in computers to do natural language processing and machine ...

Rational Software Architect
The Unified Modeling Language (UML) is a general-purpose, developmental modeling language in the field of software engineering that is intended to provide a standard way to visualize the design of a system. The creation of UML was originally motivated by the desire to standardize the disparate notational systems and approaches to software design. It was developed at Rational Software in 1994–1995, with further development led by them through 1996. In 1997, UML was adopted as a standard by the Object Management Group (OMG), and has been managed by this organization ever since. In 2005, UML was also published by the International Organization for Standardization (ISO) as an approved ISO standard. Since then the standard has been periodically revised to cover the latest revision of UML. In software engineering, most practitioners do not use UML, but instead produce informal hand drawn diagrams; these diagrams, however, often include elements from UML. History Before UML 1 ...

RSA (missile)
The RSA is one of the earliest surface-to-air missiles systems, developed by the Swiss companies Oerlikon-Bührle and Contraves starting in 1947. The missile went through a rapid development process with several upgraded versions, and was the first anti-aircraft missile offered for commercial sale when it was placed on the market in the RSC-50 form. The US tested 25 of the slightly different RSC-51 model under the name MX-1868. No further sales were forthcoming. Several improved versions followed, including the RSC-54, RSC-56, RSC-57 and RSC/RSD-58. These saw small numbers of sales, mostly as training rounds. History Background Oerlikon had been a leader in the development of anti-aircraft weapons after its purchase of the SEMAG company in 1924, and the subsequent takeover by Emil Georg Bührle the next year. Their most famous products were the variety of Oerlikon 20 mm cannon that started at SEMAG and underwent considerable further development prior to the opening of World War II. ...

RSA Numbers
In mathematics, the RSA numbers are a set of large semiprimes (numbers with exactly two prime factors) that were part of the RSA Factoring Challenge. The challenge was to find the prime factors of each number. It was created by RSA Laboratories in March 1991 to encourage research into computational number theory and the practical difficulty of factoring large integers. The challenge was ended in 2007. RSA Laboratories (which is an acronym of the creators of the technique; Rivest, Shamir and Adleman) published a number of semiprimes with 100 to 617 decimal digits. Cash prizes of varying size, up to US$200,000 (and prizes up to $20,000 awarded), were offered for factorization of some of them. The smallest RSA number was factored in a few days. Most of the numbers have still not been factored and many of them are expected to remain unfactored for many years to come. , the smallest 23 of the 54 listed numbers have been factored. While the RSA challenge officially ended in 2007, people ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RSA Factoring Challenge
The RSA Factoring Challenge was a challenge put forward by RSA Laboratories on March 18, 1991 to encourage research into computational number theory and the practical difficulty of factoring large integers and cracking RSA keys used in cryptography. They published a list of semiprimes (numbers with exactly two prime factors) known as the RSA numbers, with a cash prize for the successful factorization of some of them. The smallest of them, a 100-decimal digit number called RSA-100 was factored by April 1, 1991. Many of the bigger numbers have still not been factored and are expected to remain unfactored for quite some time, however advances in quantum computers make this prediction uncertain due to Shor's algorithm. In 2001, RSA Laboratories expanded the factoring challenge and offered prizes ranging from $10,000 to $200,000 for factoring numbers from 576 bits up to 2048 bits. The RSA Factoring Challenges ended in 2007. RSA Laboratories stated: "Now that the industry has a consid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RSA Conference
The RSA Conference is a series of IT security conferences. Approximately 45,000 people attend one of the conferences each year. It was founded in 1991 as a small cryptography conference. RSA conferences take place in the United States, Europe, Asia, and the United Arab Emirates each year. The conference also hosts educational, professional networking, and awards programs. History Early history The name RSA refers to the public-key encryption technology developed by RSA Data Security, Inc., which was founded in 1982. The abbreviation stands for Rivest, Shamir, and Adleman, the inventors of the technique. The idea for the first RSA conference was conceived in 1991 in a phone call between then RSA Security CEO Jim Bidzos and the Executive Director of the Electronic Privacy Information Center. The first conference had just one panel, called "DES and DSS: Standards of Choice." It focused on why attendees should not adopt DSS, a standard that was expected to challenge RSA Security's sta ...

RSA (cryptosystem)
RSA (Rivest–Shamir–Adleman) is a public-key cryptography, public-key cryptosystem that is widely used for secure data transmission. It is also one of the oldest. The acronym "RSA" comes from the surnames of Ron Rivest, Adi Shamir and Leonard Adleman, who publicly described the algorithm in 1977. An equivalent system was developed secretly in 1973 at Government Communications Headquarters (GCHQ) (the British signals intelligence agency) by the English mathematician Clifford Cocks. That system was classified information, declassified in 1997. In a public-key cryptosystem, the encryption key is public and distinct from the decryption key, which is kept secret (private). An RSA user creates and publishes a public key based on two large prime numbers, along with an auxiliary value. The prime numbers are kept secret. Messages can be encrypted by anyone, via the public key, but can only be decoded by someone who knows the prime numbers. The security of RSA relies on the pract ...

Rsa RNA
Rsa RNAs are non-coding RNAs found in the bacterium ''Staphylococcus aureus''. The shared name comes from their discovery, and does not imply homology. Bioinformatics scans identified the 16 Rsa RNA families named RsaA-K and RsaOA-OG. Others, RsaOH-OX, were found thanks to an RNomic approach. Although the RNAs showed varying expression patterns, many of the newly discovered RNAs were shown to be Hfq-independent and most carried a C-rich motif (UCCC). RsaA Represses the translation of the transcriptional regulator MgrA by binding to its mRNA, enhances biofilm formation and decreases bacterial virulence. Other mRNAs: including SsaA-like enzymes involved in peptidoglycan metabolism and the secreted anti-inflammatory FLIPr protein were validated as direct targets of RsaA. RsaE RsaE is found in other members of the genus ''Staphylococcus'' such as ''Staphylococcus epidermidis'' and ''Staphylococcus saprophyticus'' and is the only Rsa RNA to be found outside of this genus, in '' Mac ...

Retrosynthetic Analysis
Retrosynthetic analysis is a technique for solving problems in the planning of organic syntheses. This is achieved by transforming a target molecule into simpler precursor structures regardless of any potential reactivity/interaction with reagents. Each precursor material is examined using the same method. This procedure is repeated until simple or commercially available structures are reached. These simpler/commercially available compounds can be used to form a synthesis of the target molecule. E.J. Corey formalized this concept in his book ''The Logic of Chemical Synthesis''. The power of retrosynthetic analysis becomes evident in the design of a synthesis. The goal of retrosynthetic analysis is a structural simplification. Often, a synthesis will have more than one possible synthetic route. Retrosynthesis is well suited for discovering different synthetic routes and comparing them in a logical and straightforward fashion. A database may be consulted at each stage of the analysis, ...
