MATH GLOSSARY STANDARDS SITE MAP HELP TOPICS NumberNut.com Web WELCOME TO NUMBERNUT Thanks for visiting! Right now you're on NUMBERNUT.COM . If you are looking for math information, stay on this site. You can start by choosing one of the math topics we cover. We now have three big sections on the site: BASIC MATH: Addition Subtraction Multiplication , and Division ADVANCED MATH: Fractions Decimals Percentages Ratios , and Money This site offers an introduction to mathematics and its variety of topics. It's not just for kids, it's for everyone (even if you aren't a number nut). If you're still not sure what to click, try our site map that will show you all of the topics we cover. If you surf the site and get lost in all of the information, use the search function on the side of the pages. OKAY! A new site has to start somewhere, let's start here... So you're asking, what is MATH ? Well... Here's our best definition. Mathematics is the study of quantity, structure, and change. Do you think that's a bit general? It was meant to be. Math is a part of everything in the universe. You might be a farmer that needs to measure your land or count your crops. You might be a cook who needs to know how much food to buy. You might be a nuclear physicist that is studying the movements and activity of atoms. All of those jobs use math at one point or another. Math is just as important when you go to buy a burger, as it is to help plot the movement of planets.

Compression via Arithmetic Coding in Java. Version 1.1 Apache/BSD Licensing The arithmetic coding package is licensed under the standard Apache/BSD license 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.

Galois Field Arithmetic Library www.partow.net .: Home :. .: Links :. .: Search :. .: Contact :. Main Menu About Projects Programming Miscellaneous Projects Digital Image Watermarking FastGEO Particle Engine Simulation - (P.E.S) N-Mice Simulation ... Description The branch in mathematics known as Galois theory (pronounced as "gal-wah") which is based on abstract algebra was discovered by a young brilliant french mathematician known as Evariste Galois. The branch deals mainly with the analysis and formal description of binary and unary operations upon polynomials comprised of elements within a Galois field that then describe polynomials within the field itself. The C++ Galois Field Arithmetic Library, implements a specialised version of Galois Fields known as extension fields or in other words fields of the form GF(2^m) and was developed as a base for programming tasks that involved cryptography and error correcting codes. The library is simple, consise and straight forward, it also uses a series of look-up tables to increase performance of calculations. The library is broken into three classes, Galois Field, Galois Field Element and Galois Field Polynomial. Operations such as addition, subtraction, multiplication, division, modulus and exponentiation can occur over both field elements and field polynomials and also left and right shifting can occur for field polynomials.

I hope you enjoy your stay here. My name is Yi Ouyang and in Chinese Ou Yang Yi. I am a postdoctoral fellow of the Department of Mathematics at the University of Toronto. Education I got both my BS and MS degrees from the Department of Mathematics at the University of Science and Technology of China , the youngest of the most prestigious universities in China and the proudest of all. You can find some information about my undergraduate study from our class homepage Class 8901 In 1995, I spent a year at Department of Mathematics of the Ohio State University My four years study(1996-2000) at Department of Mathematics of the University of Minnesota ended up with my Ph.D degree in June 2000 under the instruction of Professor Greg William Anderson Research My specialty is algebraic number theory and arithmetic geometry. More specifically, I apply cohomological tools to study the arithmetic properties of number fields. One topic I am studying is the universal norm distributions, which appears quite often in the theory of cyclotomic fields, elliptic curves and modular curves. I determined the group cohomology of some universal norm distributions and used the results to study the Kolyvagin recursions in Euler systems. The other topic I am studying is about the Mordell-Weil group and Selmer group of an abelian variety in number fields, in particular, in a tower of unramified extensions. I am also participating activities in the
