22. Compression Via Arithmetic Coding In Java Unrestricted opensource Java implementation of the PPM (prediction by partial matching) algorithm for text and data compression by Bob Carpenter. Builds with ant. http://www.colloquial.com/ArithmeticCoding/

Compression via Arithmetic Coding in Java. Version 1.1 Changes in Version 1.1 Exclusion statistics for more accurate estimation. Many source code optimizations, primarily at a fairly low level of detail. Overview This directory contains the distribution for a package to do compression via arithmetic coding in Java. A very brief description of arithmetic coding with lots of pointers to other material can be found in: The Arithmetic Coding Tutorial The arithmetic coding package contains a generic arithemtic coder and decoder, along with byte stream models that are subclasses of Java's I/O streams. Example statistical models include a uniform distribution, simple unigram model, and a parametric prediction by partial matching (PPM) model. Other models can be built in the framework in the same way as the examples. A prebuilt set of javadoc is available online: Javadoc for com.colloquial.arithcode Quick Start for Java Pros Download the source to target directory, cd there, unjar the source, run ant test Downloading com.colloquial.arithcode

23. Modular Arithmetic Modular arithmetic. Modular (often also Modulo) arithmetic is an unusually versatile tool discovered by KF.Gauss (17771855) in 1801. http://www.cut-the-knot.org/blue/Modulo.shtml

CTK Exchange Front Page Movie shortcuts Personal info ... Recommend this site Modular Arithmetic Modular (often also Modulo The set of numbers congruent to a modulo N is denoted [a] N . If b [a] N N . Quite often these N sets are simply identified with the corresponding remainders: [0] N N = 1,..., [N-1] N = N-1. Remainders are often called residues ; accordingly, [a]'s are also know as the residue classes N By definition, [a] N + [b] N = [a + b] N [a] N N N Subtraction is defined in an analogous manner [a] N - [b] N = [a - b] N N ring with commutative addition and multiplication. Division can't be always defined. To give an obvious example, So [5] could not be defined uniquely. We also see that something we never had either for integer or real numbers. The situation improves for prime N's in which case division can be defined uniquely. Observe multiplication tables below for prime N. (For multiplication and division tables I have removed column and row.) Every row (and column) contains all non-zero remainders mostly messed up. So every row is a permutation N field For non prime N, most rows contain zeros and repeated entries. The tables exhibit a variety of patterns. To mention a few:

A Research Training Network of the European Union Overview Partners Programme Positions Activities Project overview Developing powerful methods taken from geometry to study the arithmetical properties of algebraic equations Algebraic equations and their arithmetical properties have interested mankind since antiquity. One has only to think of the works of Pythagoras and Diophantus, which were a milestone in their time. For many centuries such problems have fascinated both serious mathematicians (Fermat, Gauss, ...) and amateurs alike. However, developments in recent years have transformed the subject into one of the central areas of mathematical research, which has relations with, or applications to, virtually every mathematical field, as well as an impact to contemporary everyday life (for example, the use of prime numbers and factorisation for encoding "smart" cards). The classical treatment of equations by analysis and geometry in the realm of complex numbers in this century has found a counterpart, in the similar theories over finite and p -adic fields, which have particular significance for arithmetic questions. The study of certain functions encoding arithmetic information and generalising the Riemann zeta-function (
