Pulse shaping filter program that finds the pole-zero locations of a transfer function, H(s), for a matched filter. H(s) equals a -desired- signal (Yout) divided by a given input signal (Yin). Both Yout and Yin are functions of frequency. Group delay may also be calculated to compliment a given data set, thus, providing a flat group delay. Minimizing Intersymbol Interference in a read/write channel for disc drives by shaping and slimming an isolated readback pulse was the main objective for writing this program.

FC-Win (tm) is a front-end program for Fortran Calculus (tm). The Fortran Calculus (FC) language is for math modeling, simulation, and optimization. FC is based on Automatic Differentiation (AD) that simplifies computer code to an absolute minimum; i.e., a mathematical model, constraints, and the objective (function) definition. Minimizing the amount of code allows the user to concentrate on the science or engineering problem at hand and not on the (numerical) process requirements to achieve an optimum solution.

An computer game that teaches mathematics whilst being fun and rewarding Entertaining education Today's technology has created new possibilities for educational products that are both efficient and entertaining. ⠀� �Mathematics – Saving Greendale ” use all those new possibilitie. The interactive content of the computer game teaches the student to really see how mathematic skills can help to solve daily problems and how it helps to play along in the game. The software program is built on the classic platform genre which is familiar to students of today and is easy to understand. Just like a computer game The program is designed as a computer game in which the main character, (Gorm or Gyda) played by the student, must help the bewitched people of Greendale to regain their mathematic skills so they can solve their day by day problems. Points are awarded for both mathematic and computer gaming skills. This makes it more rewarding and fun to use and learn mathematics. The software can provide statistics of student progress. The computer game has three difficulty levels so that all students can benefit and learn something from the game. The student can find his or hers own level and at the same time be inspired to learn more and increase the difficulty to get more points. Practice Probably the most important feature of the program is the ability to train on a desired subject. A number of problems are included in the program, each with three difficulty levels. The theory behind the problem and a way to solve the problem is only a keystroke away. As the student learns a subject he or she can move on the next subject. Advanced tools The software contains simulations of a calculator, sketch pad, graphs and adds the ability to construct objects on screen using tools such as pencil, ruler, rubber and more. All this helps in enabling the student to solve problems by using the computer. All problems can also be solved using paper and pen.

You want to make a mixture. You have ingredients composed of the same components. The proportions (percentage,content) of the components is different in each ingredient. The composition of the mixture will depend on how much of each ingredient you will add. Exact this -"how much of each ingredient"- the Mix Finder can find for you. Uses an algorithm to solve an inhomogen linear system of eaquations. Finds approximated solutions. Easy to use Window surface. Makes files to store your substances and mixtures, to load again into the Mix Finder later. The Concept: Mixture: The mixture is produced by mixing ingredients. Substances: Both the ingredients and the mixture itself are substances. Component: The substances consist of components. Content: The contents are the percentages of the components in each substance. Percentage: 1. The proportions of the components in a substance. 2. The proportions of the ingredients in the mixture. All at once: The ingredients, each constisting of the same components, but in different proportions, are mixed together to produce a mixture with the desired proportions of these components. The Iteration To find the result, i.e.: the percentages of the ingredients to get the desired mixture, it is necessary to use an iteration algorithm. The iteration of the Mix Finder is like others, e.g. the Gauss-Seidel Method to solve a linear system of equations, but more adapted to the requirements of this spezial application. Especially, if there is not an exact result possible, the Mix Finder gives a result that is best approximated to produce the desired mixture. This iteration has a low speed of convergence, but converges always. The low speed does not matter at all, with todays computers it is invisible fast.
