Extractions: Fast Marching Methods and Level Set Methods are numerical techniques which can follow the evolution of interfaces. These interfaces can develop sharp corners, break apart, and merge together. The techniques have a wide range of applications, including problems in fluid mechanics, combustion, manufacturing of computer chips, computer animation, image processing, structure of snowflakes, and the shape of soap bubbles. These are two fundamentally different approaches to the problem of tracking moving interfaces, yet they share a common theory and numerical methodology. This web page serves as both an introductory and advanced resource for these ideas, with the goal of providing an intuitive understanding of the techniques the history, evolution, and application of these methods technical details and reference material.

Extractions: i-Math Investigations are online, interactive, multimedia math investigations. All i-Maths are built around interactive math Java applets, and some also include video clips. There are two lengths of i-Maths: single-day and multi-day, as identified below. Student i-Maths contain just the student investigations. They are ready to use by students. e-Math Investigations are selected e-examples from the electronic version of NCTM's Principles and Standards for School Mathematics . Each e-example consists of an interactive math applet, suggestions for student activities, and some discussion for teachers. These investigations can be identified by the icon to the right. Single-Day i-Math Activities Developing Geometry Concepts Using Computer Programming Environments Computer programming environments can be used to help children understand geometric concepts. The interactive tool in this i-Math investigation illustrates how the LOGO programming language can be used to foster creative problem solving and encourage young students to estimate length and angle measures.
Mkaz.com : Java Matrix Calculator Last Modified June 13th, 2002. NOTE The older java Applet version of this program has been removed. I lost the complete source many computers ago. http://www.mkaz.com/math/matrix.html
Extractions: Mathematics My Articles Snapshots Author: Marcus Kazmierczak Created On: Last Modified: June 13th, 2002 NOTE: The older Java Applet version of this program has been removed. I lost the complete source many computers ago. I have re-written the GUI as a Swing application, source code is fully available. Download the Java Source: MatrixCalculator.java No special classes or libraries are used with this application. The complete source resides in the one file above. After downloading, the following should work in any JDK 1.2 compatible compiler: Ex. (3x3) Results will be placed in the C matrix. The calculation of the determinant, by definition, is based upon a factorial number of calculations with respect to the size of the matrix. ie. a 3x3 matrix would have 6 calculations (3!) to make, whereas a 20x20 matrix would have 2.43 x 10^18 calculations (20!). So instead of brute forcing the calculations, I first do some operations on the matrix, which converts it to a upper triangular matrix, and then calculate the determinant by multipling down the diagonal, since everything below is 0, this will give the determinant. Floating Points and Accuracies For some reason computers aren't as accurate as I think they are, probably my calculation techniques. The accuracy of the numbers are probably only to 3 maybe 2 decimal places. If you keep applying operations to matrices and then use the resultant matrix a couple of times, the decimals get out of whack. Calculating an inverse and then multplying the matrix by it, is a good example of this.
Aritm It is always good to do an Aritm workout before you are going to a math test. Orbin Web Technology. java applets Mikael Bonnier s home page. http://www.df.lth.se/~mikaelb/aritm/aritm.shtml
Extractions: Showed for the time. Aritm trains you in simple mental calculation. This program teaches its users the addition, subtraction, multiplication, and division tables. It employs a very effective method, which makes the process short with these useful tables. If you know these tables it is much easier to follow the matematics education. Further more, you can use them in everyday situations, especially if you also know rough estimate calculation. These tables, neither more nor less, is everything you need to know by heart, because there are manual methods for calculating with more complicated numbers. It is always good to do an Aritm workout before you are going to a math test. Also, you can use Aritm to train calculation in foreign languages. You can mix the problems anyway you like, e.g you can choose addition and multiplication at the same time. The difference of two small terms. The difference of one larger term and one smaller.

Go back to MCell Home Mirek's Java Cellebration (MJCell) is a Java applet that allows playing 300+ Cellular Automata rules and 1400+ patterns. It can play rules from 13 CA rules families: Generations Life Vote Weighted Life ... Larger than Life , and some of the User DLLs . It allows also to experiment with own rules. The applet is a simplified version of MCell. It does not offer extended features of MCell, but has one advantage over it: its usage is not restricted to MS Windows. Full source code of the applet is available here . You can also download the full off-line version equipped in a rich library of patterns. You should also download this version if you plan to put the MJCell applet on your own Web page. To start the applet, click on the "Start" button below. The applet will show up in its own window.

Breaking The Vigenere Encryption System with a new trial period. The Applet below is programmed to illustrate this codebreaking process. Upon pressing the Random Cyphertext http://math.ucsd.edu/~crypto/java/EARLYCIPHERS/Vigenere.html
Extractions: Breaking The Vigenere Encryption System W e recall that a Caesar k -shift is the circular permutation which replaces each letter of the alphabet by the letter k places later (with wrap around). In Vigenere encryption, the key consists of a period p and a sequence k ,k ,k p of Caesar shifts. This given, the plaintext is broken up into successive strings of p letters each and the s th letter of each string is replaced by its image under the Caesar k s -shift. This encryption system is vulnerable to letter-frequency analysis. The letter frequencies observed in the sequence of s th letters have the same distribution as the plaintext letters only k s -shifted. T o break Vigenere encryption, one guesses a period p and then, by comparing the histogram of observed frequencies of s th letters to the histogram of English letter probabilities, one is led to the correct value of k s . A wrong guess for the period p leads to relatively flat histograms for all or most of the values of s . The code breaker in this case repeats the analysis with a new trial period. T he Applet below is programmed to illustrate this codebreaking process.
Pascal Triangle coefficients III Any integer divides almost all binomial coefficients, J. London math. Soc. It includes a standard module from Core java package. The applet. http://www.math.ohio-state.edu/~btk/Pascal/
Extractions: present This applet graphically presents the Pascal triangle modulo an integer number p, i.e. it computes the binomial coefficients mod p and then plots them. The zero (mod p) values are depicted by gray dots, the non-zero values- by black dots. I shall call the resulting figure the "Pascal gasket of order p". If you try out my applet, you will see that if p=2 then the resulting picture is the Sierpinski gasket. It is a fractal of dimension less than 2, so its area (two-dimensional Hausdorff measure) is zero. This shows that in a certain sense almost all binomial coefficients are even. Actually ( D.Singmaster, Notes on binomial coefficients III Any integer divides almost all binomial coefficients , J. London Math. Soc. ) same is true for every integer p>1. This means in particular that the area of every Pascal gasket is zero, though you can't quite see it from the picture, say, for p = 15000! For more information see: Ian Stewart, Four Encounters with Sierpinski's Gasket.
