DMV

DMV The Diffusion Model allows for modelling response times. The Diffusion Model Visualizer explores the effect of the seven model parameters (a, z, v, t0, sz, sv, and st0) upon the response time density curves and positive/negative response probabilities. It supports interactive parameter change with immediate update of the diagram. The diagram can be stored to disk for further use (e.g., in an article or educ=ational context). The program is freeware.

See the "The diffusion model visualizer: an interactive tool to understand the diffusion model parameters" (Journal Psychological Research; DOI: 10.1007/s00426-018-1112-6 Article) for further information regarding technical details and usage.

FREE!ship Plus in Lazarus

FREE!ship Plus in Lazarus is further development of the FREE!ship Plus Windows program based on the free source code FREE!ship v3.x under GNU GPL license. This FREE!ship Plus application is migrated into free open source Lazarus / Free Pascal environment to promote further development in various platforms and for various platforms (OS and architectures).

FREE!ship Plus is designed for the full parametric analysis of resistance and power prediction for a ship and other calculations of hydrodynamics of vessels and underwater vehicles. FREE!ship Plus allows the designer to simulate and analyze condition of balance of a complex completely hull - rudders - keels - engine - propellers in different regimes and of service conditions of a ship. The analyzable system includes a hull, appendages, a propeller and the engine (i.e. resistance, power, a thrust and a torque), and also various service conditions (heaving, a wind, a shallow-water effect, a regime of tow / pushing, etc...).

Harmonux

Harmonux 0.1.4 Harmonic Analysis. Enter a table and get the harmonic function for the table. With the graphic of the points of the table and the function. Open Source GNU/GPL, pre-compiled for Linux and Windows.

LazBacterias

LazBacterias is a program to simulate the growth of bacterial cultures using the rules of Conway's Game of Life.

MRIcron

MRIcron is an opensource project that allows users to visualize and volume render medical images (MRI, CT, PET). It includes tools for lesion mapping, non parametric statistical analysis (npm), and conversion from the medical DICOM format to the scientific NIfTI format (dcm2nii). It is available for Windows, Linux and macOS.

MRIcroGL

MRIcroGL is an opensource project that uses the graphics card (using OpenGL) to visualize and volume render medical images. It is hosted on the National Institutes of Health (NIH) Neuroimaging Informatics Tools and Resources Clearinghouse (NITRC). It can view images saved in NIfTI (.nii, .nii.gz, .hdr/.img), Bio-Rad Pic (.pic), NRRD, Philips (.par/.rec), ITK MetaImage (.mhd, .mha), AFNI (.head/.brik), Freesurfer (.mgh, .mgz), and many DICOM (extensions vary) formats. It is available for Windows, Linux and macOS.

Nest-o-Patch

Nest-o-Patch, software for the analysis of patch-clamp, two-electrode-voltage clamp and other electrophysiological data. Directly works with files created by HEKA Pulse or Patch-Master data aquisition software or with CSV and text files. Designed mostly for the analysis of single channel recordings, was nevertheless successfully used for whole-cell data analysis. Several academic papers were published with the use of this software.

OctaveGUI

OctaveGUI is a(nother) GUI frontend for GNU Octave written fully in Free Pascal with Lazarus IDE, with the following feature goals: Cross platform (CPU, OS, and widgetset) - Portable - Small size - Fast execution & low memory consumption - Close interface to MATLAB.

OpenSIMPLY

Project homepage OpenSIMPLY is an open source free simulation software based on discrete event simulation approach. The concept is suitable for a person of a different programming and simulation experience. Both style of simulation: blocks simulation and Simula-like simulation are available. Simula-models with some adaptation can be used as well. The project is supplied with full documentation (HTML and CHM formats), insight help (pop-up hints) and tutorial with executable examples. OpenSIMPLY can be used as a network simulation software, traffic simulation software and as a computer simulation software for educational purposes. The project contains the Simply Memory Manager.

ProofTools

ProofTools automatically and graphically generates semantic tableaux, also known as proof trees, semantic trees and analytic tableaux, generally used to test whether a formula is a logical truth, or whether a proof/argument is deductively valid. ProofTools can generate proof trees for propositional, predicate and (normal) modal logic. It is available for Windows, Linux and macOS.

SimSEE

SimSEE is a platform for Simulation of Systems of Electrical Energy. Using SimSEE we can simulate the optimal operation of systems with hydroelectrical plants, hydro-reservoirs, fuel fired plants, wind farms and interconnections with other countries. The platform has a very sophisticated tool for modelling stochastic processes like river inflows, fuel prices, wind speed, etc. The software was developed in Spanish but we are working to support other languages (help is welcome).

SimThyr

SimThyr is a simulation program for the pituitary thyroid feedback control that is based on a parametrically isomorphic model of the overall system. It aims in a better insight into the dynamics of thyrotropic feedback. Applications of this program cover research, including development of hypotheses, and education of students in biology and medicine, nurses and patients.

SPINA

SPINA is software for determining constant structure-parameters of endocrine feedback control systems from hormone levels obtained in vivo. The first version of this cybernetic approach allows for evaluating the functional status of the thyroid gland.

SysLinea

SysLinea 0.1.2 Solves Linear Systems and calculates Linear and Non linear Regression. It gives the Pearson and Spearman coefficients of correlation and the t-test. Open Source GNU/GPL, pre-compiled for Linux and Windows.

SysLinea 1.2 - Linear regression and non linear regression

Traverse Pro

Traversing is the type of survey in which a number of connected survey lines form the framework and the directions and lengths of the survey lines are measured with the help of an angle measuring instrument respectively. Traverse Pro is a freeware for calculation of single loop traverse. Traverse Pro desktop application especially designed for Civil / Surveyor. Download.

Unified Life Models

ULM (Unified Life Models) is an open-source software enabling the simulation and analysis of deterministic and stochastic discrete time dynamical systems for population dynamics modeling. It works natively on Windows, Linux and macOS.

Models are described using a simple declaration language, close to the mathematical formulation. The system can be studied interactively by means of simple commands, producing convenient graphics and numerical results.

Xoctave

Xoctave is a Human interface to GNU Octave. Xoctave encapsulates GNU Octave uses pipes and provides extra useful tools to make GNU Octave more easier to use. XOctave is written in Pascal using Lazarus front-end and Free Pascal (aka FPK Pascal) libraries. It uses synedit for syntax highlighting, and uses the Lazarus Component Library (LCL) is a set of visual and non-visual component classes over a Widget toolkit-dependent layer with multi-language support (English-Turkish)
