The SART algorithm ( Simultaneous Algebraic Reconstruction Technique ) proposed by Andersen and Kak in 1984 has had a major impact in CT imaging

In 1930, Societatea Anonimă Română de Telefoane ( SART, " Romanian Telephone Company, Ltd .") was founded, more than 90 % of its value being a foreign investment from ITT.

In 1949, SART was nationalised and turned into a division of the Ministry of Posts and Telecommunications.

Systems with 10 to 100 N of thrust have been investigated by SART.

The GMDSS installation on ships include one ( two on vessels over 500 GT ) Search and Rescue Locating device ( s ) called Search and Rescue Radar Transponders ( SART ) which are used to locate survival craft or distressed vessels by creating a series of twelve dots on a rescuing ship's 3 cm radar display.

In addition to equipment listed below, all GMDSS-regulated ships must carry a satellite EPIRB, a NAVTEX receiver ( if they travel in any areas served by NAVTEX ), an Inmarsat-C SafetyNET receiver ( if they travel in any areas not served by NAVTEX ), a DSC-equipped VHF radiotelephone, two ( if between 300 and less than 500 GRT ) or three VHF handhelds ( if 500 GRT or more ), and two 9 GHz search and rescue radar transponders ( SART ).

Researchers have also studied how SART can best be implemented on

SART: OS-SART, FA-SART, VW-OS-SART, SARTF, etc.

SART and its proposed extensions are used in emission CT in nuclear medicine, for dynamic CT, for holographic tomography, etc.

In addition, a distress can be signaled using automated radio signals such as a Search and Rescue Transponder ( SART ) which responds to 9GHz radar signal, or a Emergency Position-Indicating Radio Beacon ( EPIRB ) which operates in the 406 MHz radio frequency.

JDI works with corrections agencies to bring the SART model into the prison context, providing incarcerated survivors of sexual abuse with the same quality of care that is available in the community.

During this period ( 1930 – 1933 ), SART commissioned Palatul Telefoanelor ( The Telephone Palace ), a historic building in Bucharest.

A Search and Rescue Transponder ( SART ) is a self contained, waterproof radar transponder intended for emergency use at sea.

A SART will only respond to a 9 GHz X-band ( 3 cm wavelength ) radar.

Each radar pulse received causes the SART to transmit a response which is swept repetitively across the complete radar frequency band.

He was highly influential in the development of computer science, giving a formalisation of the concepts of " algorithm " and " computation " with the Turing machine, which can be considered a model of a general purpose computer.

In 2002, a theoretical attack, termed the " XSL attack ", was announced by Nicolas Courtois and Josef Pieprzyk, purporting to show a weakness in the AES algorithm due to its simple description .< ref >

ALGOL ( short for ALGOrithmic Language ) is a family of imperative computer programming languages originally developed in the mid 1950s which greatly influenced many other languages and was the standard method for algorithm description used by the ACM, in textbooks, and academic works for the next 30 years and more.

He also was the original author of rzip, which uses a similar algorithm to rsync.

In 1929, Mojżesz Presburger showed that the theory of natural numbers with addition and equality ( now called Presburger arithmetic in his honor ) is decidable and gave an algorithm that could determine if a given sentence in the language was true or false.

On September 30, 1935 an exclusive conference was held in Rome with the topic of high velocity flight and the possibility of breaking the sound barrier.

A notable example was Phil Katz's PKARC ( and later PKZIP, using the same ". zip " algorithm that WinZip and other popular archivers now use ); also other concepts of software distribution like freeware, postcardware like JPEGview and donationware like Red Ryder for the Macintosh first appeared on BBS sites.

But the study of these curves was first developed in 1959 by mathematician Paul de Casteljau using de Casteljau's algorithm, a numerically stable method to evaluate Bézier curves.

The basic search procedure was proposed in two seminal papers in the early 60s ( see references below ) and is now commonly referred to as the Davis – Putnam – Logemann – Loveland algorithm (" DPLL " or " DLL ").

Huffman coding is the most known algorithm for deriving prefix codes, so prefix codes are also widely referred to as " Huffman codes ", even when the code was not produced by a Huffman algorithm.

A simple Internet search finds millions of sequences in HTML pages for which the algorithm to replace an ampersand by the corresponding character entity reference was probably applied repeatedly.

As of 2002, an asymmetric key length of 1024 bits was generally considered the minimum necessary for the RSA encryption algorithm.

It was then analyzed by researchers in the company, and signal processing expert John Platt designed an improved version of the algorithm.

What amounts to an algorithm for solving this problem was described by Aryabhata ( 6th century ; see ).

Developed in the early 1970s at IBM and based on an earlier design by Horst Feistel, the algorithm was submitted to the National Bureau of Standards ( NBS ) following the agency's invitation to propose a candidate for the protection of sensitive, unclassified electronic government data.

This time, IBM submitted a candidate which was deemed acceptable — a cipher developed during the period 1973 – 1974 based on an earlier algorithm, Horst Feistel's Lucifer cipher.

The suspicion was that the algorithm had been covertly weakened by the intelligence agency so that they — but no-one else — could easily read encrypted messages.

Another theoretical attack, linear cryptanalysis, was published in 1994, but it was a brute force attack in 1998 that demonstrated that DES could be attacked very practically, and highlighted the need for a replacement algorithm.

Now there was an algorithm to study.

It was noted by Biham and Shamir that DES is surprisingly resistant to differential cryptanalysis, in the sense that even small modifications to the algorithm would make it much more susceptible.

A divide and conquer algorithm for triangulations in two dimensions is due to Lee and Schachter which was improved by Guibas and Stolfi and later by Dwyer.

The original algorithm was described only for natural numbers and geometric lengths ( real numbers ), but the algorithm was generalized in the 19th century to other types of numbers, such as Gaussian integers and polynomials in one variable.
