DeepThought is an universal equations and equations systems solver.

Cinema 4D plugins previously maintained and hosted at http://www.defcon-x.de/c4d-plugins. Includes the following: * Advanced Atom Array (AAA) * Align to Vector Tool (AVT) * Flange Maker

Metaphone is a phonetic hash, similar to Soundex but more specific.

Finds communities in networks with a submodular algorithm based on the optimization of Newman's modularity. The algorithm finds a weakly optimal community partition of the network. Developed by J. R. Busch, M. G. Beiro and J. I. Alvarez-Hamelin,

Depth Explorer is a visual interactive tool for learning about Statistical Data Depth and evaluating depth measures.

Descend is an open source program for drawing 3D surfaces from parametric equations. It uses a custom, very fast language called Misc to calculate the geometry. It also uses OpenGL to render scenes with high quality shaders. Website: https://descend.mimec.org/

Diagonal can be used for: - getting descriptive statistics such as mean/median/mode with your program producing a sample - finding a root of an equation your program defines - calculating a fixed point of a function your program defines - detecting a cycle of a fuction your program defines as well as - decoding a VCDIFF file

This program was made, because from my question that I had, if the manufacturers tell the truth about the dimensions (inch's) of their monitors and if the analogy (ratio) is indeed the named one, and also because I wanted to know the dimensions in cm's for a tv 32" or 40" and also whats the relation with the Greek Golden Number Φ. (A litle explanation and links about Φ exists at the end of this page).

Diffeq is a free software for solving differential equations.

This is a suite for numerically solving differential equations written in Julia and available for use in Julia, Python, and R. The purpose of this package is to supply efficient Julia implementations of solvers for various differential equations. The well-optimized DifferentialEquations solvers benchmark as some of the fastest implementations, using classic algorithms and ones from recent research which routinely outperform the “standard” C/Fortran methods, and include algorithms optimized for high-precision and HPC applications. At the same time, it wraps the classic C/Fortran methods, making it easy to switch over to them whenever necessary. Solving differential equations with different methods from different languages and packages can be done by changing one line of code, allowing for easy benchmarking to ensure you are using the fastest method possible.

Digital Psionics develops a variety of scientific and entertainment software.

A Java implementation of the Dijkstra bestpath algorithm.

Simple Dijkstra shortest path implementation - for learning and teaching

Diktyologia is software for investigating complex systems with advanced methods of network theory. The package allows for analysing statistical properties of directed intercausal networks that are represented in form of cy.prus XML files.

A Python package that provides classes and tools for dealing with dimensional quantities. Includes a parser for the quantity language (i.e. calculates "3 meters per second in miles per hour") and a class for constructing matrices containing dimensions.

The Dimensional Analysis tool is meant to be used with spreadsheets containing variable definitions and formulas with physical units. It will execute the definitions and the formulas; and calculate the resulting units. The spreadsheet must follow a standard for the variables and the formulas. The general convention is to put variable names, values & formulas, and units in three columns. Make sure the names match the contents of the name cells. Use the names in the formulas, not the cell addresses. To use the Dimension Analysis tool, select and copy the cells, then paste them into the tool’s input text box. Requires Python 3 plus SymPy and mpmath packages. http://www.sympy.org http://mpmath.org/

Diofantos is a library for the solution of equations that arise in physics. It deals with ordinary differential equations (ODE), partial differential equations (PDE), including grid generation, and integral equations.

This is a program for numerical solution of Euler equations of compressible flows using discontinuous galerkin method. The code is written on top of the deal.II finite element library. Code has been moved to https://github.com/cpraveen/dflo

Shared objects for algebra (moves) on various surfaces (game boards) including cylinders, helices, spheres, hemispheres, tori, Mobius' strip, Klein's bottles, ...

Accompanying software for the paper "Optimal Decision Rules for the Discursive Dilemma", by A. Alabert, M. Farré and R. Montes (https://arxiv.org/abs/2210.13100). Computes a ranking of the best decision rules according to a quantitative criterion based on the minimisation of the combined probabilities of false positives and false negatives

C Library designed to generate in sequence permutations or combinations (possible orderings or subsets) of objects, with or without repetition. To demonstrate the use of the library, a command-line program (disp) and a GTK graphical version (GDisp) are provided too, useful to teach combinatorics.

We have moved, the project is now at http://distancesampling.org

This library allows developers to quickly add to their code management of probability laws. The Distri library gives close control to random distribution for each possible value. The distribution can also be directly modified by the user of the applica

A project aims to develop a system which trains LDA model in distributed enviorenment. I studied Hadoop based solution and found that Hadoop is not fit for distributed LDA training case. In this project I implement a platform based on socket.
