Free integrator software for linux

odf-converter-integrator 0.2.3 offers users an easy way to open Microsoft Office 2007 files (also called Office Open XML, .xlsx, .docx and .pptx) with a high-quality conversion on any Linux or Windows system in any OpenOffice.org.

Major Features:

1. odf-converter-integrator uses the high-quality odf-converter code (which converts between Office Open XML and OpenDocument) as packaged by Novell and integrates it into the operating system.
2. When you click on a .docx/.xlsx/.pptx file on a web page, in an email attachment, or your desktop, odf-converter-integrator springs into action, converts the .docx/.xlsx/.pptx to an .odt/.ods/.odp, and then automatically opens the new document in OpenOffice.org, StarOffice, Abiword, KWord, Gnumeric, Microsoft Office 2003, or whatever is your default ODF editor.
   
3. odf-converter-integrator is simply a little glue to overcomes the integration limitation of the Novell odf-converter, which cannot integrate into most editions of OpenOffice.org (such as the vanilla/Sun Microsystems edition, Fedora, OxygenOffice, and others).

Enhancements: This release fixes a bug that prevented conversion of any .xlsx files on Linux.

Mantissa is a collection of various mathematical tools aimed towards for simulation.
Mantissa contains a collection of algorithms, among which:
a small set of linear algebra classes
a least squares estimator
some curve fitting classes
several ordinary differentials equations integrators, either with fixed steps or adaptive stepsize control (see below)
vectors and rotations in a three dimensional space
algebra-related classes like rational and double polynomials
various orthogonal polynomials:
Chebyshev
Hermite
Laguerre
Legendre
some random numbers and vectors generation classes:
Robert M. Ziff four tap shift register (contributed by Bill Maier)
Makoto Matsumoto and Takuji Nishimura Mersenne twister
generators for vectors with correlated components
some basic (min, max, mean, standard deviation) statistical analysis classes
some optimization algorithms using direct search methods:
the Nelder-Mead simplex method
Virginia Torczons multi-directional method
Enhancements:
- For many basic objects provided by Mantissa like Vector3D, Rotation, and the various Polynomial classes, instances are now guaranteed to be immutable.
- This greatly simplifies safe sharing of instances without forcing users to either put severe restrictions on their use of Mantissa classes or make numerous copies just to make sure everything is safe.
- Since the change is a semantic change on the contract of the classes, this version introduces some incompatibilities with respect to previous ones.
- Upgrading to this version is not difficult, though.

Nonpareil is a microassembler and simulator package for the calculators. It currently supports the HP Classic and Woodstock series. Nonpareil is written in C and uses the GTK+ toolkit.
The Classic series of HP handheld calculators included the following models:
- HP-35 Scientific (Electronic Slide Rule)
- HP-80 Financial
- HP-45 Advanced Scientific
- HP-65 Card Programmable Scientific
- HP-70 Business
- HP-55 Programmable Scientific
The HP-67 is considered by many people to be part of the Classic series since it is packaged similarly to the HP-65, but electrically it is really a Woodstock series machine.
The classic series chip set was also used in the HP-46 and HP-81, which were desktop printing versions of the HP-45 and HP-80, respectively, and the HP 9805A desktop calculator. The same chip set was also used in the HP 1722A Oscilliscope, the HP 3380A Integrator (for Gas Chromatography), and in several HP Gas Chromatographs.
The Woodstock series of HP handheld calculators included the following models:
- HP-21 Scientific
- HP-22 Financial
- HP-25 Programmable Scientific
- HP-25C Programmable Scientific with continuous memory
- HP-27 Scientific and Financial
- HP-29C Programmable Scientific with continuous memory
The code name "Woodstock" referred both to the Woodstock series of calculators, and to the processor architecture use in them. The same processor architecture was also used in the Topcat, Sting, and Spice series, and the HP-67.
Enhancements:
- Build problems that occurred with certain versions of Bison were fixed.
- The need for an X server during the build process was eliminated.

Cell Electrophysiology Simulation Environment (CESE) is a comprehensive framework specifically designed to perform computational electrophysiological simulations, for example, simulations of cardiac myocyte electrical activity.
Cell Electrophysiology Simulation Environment is useful for simulations of action potentials, individual ionic currents, and changes in ionic concentrations.
CESE is a cross-platform program, it runs on any system that has Java runtime environment (JRE) version 1.4 or above. It was tested on Windows, Linux, Solaris, MacOS X, and AIX.
CESE users
CESE is an integrated environment for performing computational simulations using a variety of electrophysiological models.
At this stage CESE allows creation and execution of the single-cell models (containing both Hodgkin-Huxley (HH) and Markovian current formulations). Models of electrical activity of cardiac myocytes with source code are included in the CESE distribution. We hope to extend the number of available models, and add certain neuronal models in the future.
The main strength of CESE is in its uniformity ? a program interface remains the same for different types of models. You can easily switch between models and compare simulation outputs. Model parameters can be modified, selected for output and/or clamped in the same, standard way.
CESE extends the conventional electrophysiological meaning of the "voltage clamp". You can clamp virtually any model variable, including voltage (membrane potential), total or individual ionic currents, ionic concentrations, temperature, gating variables, etc. The clamping commands can be complex piece-wise functions, individually set for the model variable of interest. This opens endless possibilities for the exploration of complex model behavior.
CESE provides simple, but efficient data visualizations. Simulation results can be presented in the graphic and tabulated forms. Plots can be customized, and regions of interest zoomed.
Even though CESE was not designed to be a data analysis tool, you can generate current-voltage relationships (I-Vs) and calculate statistical parameters for a given signal within the program. You can export your data to ASCII, Axon Text File (ATF), and NetCDF formats to continue analysis in your favorite package.
CESE developers
CESE was created from the ground up to incorporate the best programming practices available to Java developers, both in terms of user interface consistency and code clarity and reuse. Wherever possible, CESE rely on available Java APIs (for example Java2D, JavaBeans, JAXP) to simplify the code.
Model creation requires a number of house-keeping functions to be coded ? these include ODE integrators, routines for handling model parameters, saving/restoring model state, visualizing simulation results, etc. CESE provides you with implementation for these routines, hence, you can concentrate on writing the code for concrete ionic current(s), and CESE will handle the rest.
CESE is not trying to create complicated programming frameworks on its own ? rather, it utilizes core Java APIs. For example, models are Java components conforming to the JavaBeans specification. We use XML to specify clamping commands, and Java object serialization to save/restore model parameters.
Enhancements:
- This release improves results printing, adds export to the scalable vector graphics (SVG) format, improves support for continuous simulations, and fixes many bugs in plot rendering and model switching.

ParaView project is an application designed with the need to visualize large data sets in mind. The goals of the ParaView project include the following:
- Develop an open-source, multi-platform visualization application.
- Support distributed computation models to process large data sets.
- Create an open, flexible, and intuitive user interface.
- Develop an extensible architecture based on open standards.
ParaView runs on distributed and shared memory parallel as well as single processor systems and has been succesfully tested on Windows, Linux and various Unix workstations and clusters. Under the hood, ParaView uses the Visualization Toolkit as the data processing and rendering engine and has a user interface written using a unique blend of Tcl/Tk and C++. Please go here for a detailed list of features.
ParaView was created by Kitware in conjunction with Jim Ahrens of the Advanced Computing Laboratory at Los Alamos National Laboratory (LANL). Contributors and developers of ParaView currently include: Kitware, LANL, Sandia National Laboratories, and Army Research Laboratory. ParaView is funded by the US Department of Energy ASCI Views program as part of a three-year contract awarded to Kitware, Inc. by a consortium of three National Labs - Los Alamos, Sandia, and Livermore. The goal of the project is to develop scalable parallel processing tools with an emphasis on distributed memory implementations. The project includes parallel algorithms, infrastructure, I/O, support, and display devices. One significant feature of the contract is that all software developed is to be delivered open source. Hence ParaView is available as an open-source system.
Main features:
- Handles structured (uniform rectilinear, non-uniform rectilinear, and curvilinear grids), unstructured, polygonal and image data.
- All processing operations (filters) produce datasets. This allows the user to either further process or save as a data file the result of every operation. For example, the user can extract a cut surface, reduce the number of points on this surface by masking, and apply glyphs (for example, vector arrows) to the result.
- Contours and isosurfaces can be extracted from all data types using scalars or vector components. The results can be colored by any other variable or processed further. When possible, structured data contours/isosurfaces are extracted with fast and efficient algorithms which make use of the special data layout.
- Vectors fields can be inspected by applying glyphs (arrows, cones, lines, spheres, and various 2D glyphs) to the points in a dataset. The glyphs can be scaled by scalars, vector component or vector magnitude and can be oriented using a vector field.
- A sub-region of a dataset can be extracted by cutting or clipping with an arbitrary plane (all data types), specifying a threshold criteria to exclude cells (all data types) and/or specifying a VOI (volume of interest - structured data types only)
- Streamlines can be generated using constant step or adaptive integrators. The results can be displayed as points, lines, tubes, ribbons, etc., and can be processed by a multitude of filters.
- The points in a dataset can be warped (displaced) with scalars (given a user defined displacement vector) or with vectors (unavailable for non-linear rectilinear grids).
- With the array calculator, new variables can be computed using existing point or cell field arrays. A multitude of scalar and vector operations are supported.
- Data can be probed at a point or along a line. The results are displayed either graphically or as text and can be exported for further analysis.
- ParaView provides many other data sources and filters by default (edge extraction, surface extraction, reflection, decimation, extrusion, smoothing...) and any VTK filter can be added by providing a simple XML description (VTK provides hundreds of sources and filters, see VTK documentation for a complete list).
Enhancements:
- This release adds parallel uniform rectilinear grid volume rendering (vtkImageData).
- It introduces new algorithms for parallel unstructured grid volume rendering.
- Support for hardware accelerated offscreen rendering using OpenGL framebuffers.
- Improved multi-block support.
- Improved AMR support.
- Animation saving with ffmpeg.
- Filters have been added for FLUENT, OpenFOAM, MFIX, LSDyna, and AcuSolve.
- A gradient filter for unstructured data.
- Many other enhancements and bugfixes.
