Sweet Home 3D v3.0

Sweet Home 3D is a free interior design application that helps you placing your furniture on a house 2D plan, with a 3D preview. Sweet Home 3D comes with 50 pieces of furniture, but you may also import some additional objects in it. To get more objects, please visit this regularly updated page.
Sweet Home 3D provides a full help accessible from its Help > Sweet Home 3D Help menu.
What's New in version 3.0:

Displayed selected light sources with wireframe spheres in the 3D view.
Changed the indicator and the behavior of the bottom left corner of lights to be able to update their light power.

Added the Part of base plan option to furniture modification dialog to be able to lock a piece of furniture when the base plan is locked.
Included all non movable furniture in the locked plan.
Improved the computing of shadows on the floor of 3D models containing many vertices to avoid the program to hang at the second quality photo rendering level.
Improved the computing of the max altitude and the 3D rendering in Aerial view mode.
Updated wrong normals values in some 3D models of the default catalog to improve their rendering.
Added a cross hatch pattern for walls.
Print / Copy / Export of the background image if it's displayed in the plan.
Managed saving of homes data at regular time intervals in a private folder, with automatic recovery of homes in case the program crashed.
Added automatic deletion of temporary files created by Sweet Home 3D older than a week.
Kept shapes prefix of furniture exported at OBJ format, to restore prefixed shapes properties correctly at reimporation time.
Saved Sweet Home 3D preferences in a file independent from Operating System preferences to simplify the transfer of Sweet Home 3D configuration to an other computer.
Added com.eteks.sweethome3d.preferencesFolder and com.eteks.sweethome3d.applicationFolders system properties to set the folders where are stored Sweet Home 3D preferences and SH3F, SH3T, SH3L and SH3P files.
Increased the recent files maximum count to 10.
Waited for a first move of the mouse pointer before duplicating selected items when the ctrl key (or alt key under Mac OS X) is pressed.
Improved items move with the mouse when they are very small in the plan.
Increased the moves of selected items in the plan when the keyboard arrows are pressed with the shift key.
Reversed the effect of pressing the shift key for moves in the 3D view.
Correction de bugs qui empêchaient le bon affichage des sols des pièces qui se chevauchent.
Updated help pages (only in English and French in this version).
Removed the ID column from the columns list displayed in Furniture Library Editor.
Replaced JRE 6u21 by JRE 6u22 in Sweet Home 3D installers bundled with Java.

Antaeus 3.3

Antaeus is a utility that lets you create and explore data plots with ease. These plots can be used to confirm or deny the merits of statistical analyses performed from other applications. They can also be used to find patterns in multivariate data that can only be discovered through the use of visual investigation.
Antaeus is meant to supplement statistical analyses by allowing investigators to study the plots that correspond to their formulations, but no statistics is used within Antaeus itself.
Antaeus is also a platform from which plots may be published. Any plot may be saved to clipboard or file (when too large for the clipboard) as a Windows Enhanced Metafile (EMF). These can be embedded in reports, papers, and presentations created in Microsoft Office products such as Word, PowerPoint and Publisher.
Support for EMF files is also increasing among non-Microsoft publication suites. These sophisticated programs are empowered by the use of plots they cannot possibly construct themselves.
Antaeus runs on Windows Vista, XP, and 7. It is free for academic and non-commercial use.

yoshinoGRAPH 3.0.0

yoshinoGRAPH is a scientific graph software for data analysis and presentation. You can make 2D and 3D graphs quickly from data files in text format. This software is tiny but includes many basic functions to analyze/edit data as well as rather advanced ones.

Features:

• easy to make sientific graphs for presentation and publication
• plot styles: scatter charts, density and 3D plots
  
• special 2D plots: density, double y-axis, shift data along y-direction with z values
  
• easy to change scales among linear, log, inverse and reverse
  
• auto fitting: polynomial, 3rd spline, Gaussian and other arbitrary functions
  
• manual fitting with two independent lines
  
• easy to remove scattered/noisy data
  
• many functios to convert data: quick sort, numerical differentiation, smoothing, making tables, convert with mathematical expressions and so on
  
• to draw a math function on 2D graph using an expression
  
• to copy a graph in metafile and bitmap formats to paste it on a presentation software
  
• easy to read many data files saved in different folders
  

yoshinoGRAPH has been developed just for myself to handle data of transport phenomena of organic conductors but I wish it also assists you to pursue your own research.

• includes a Database Abstraction Layer with drivers for MySQL AND PostgreSQL
• Web-based accessible interface, compatible with almost all modern internet browsers
• includes a protected administration area from which it is possible to manage the whole system
• supports different access levels both for users and resources (pages, forms, sections)
• includes an additional security system to access the tests based on the check of the IP addresses
• supports an unlimited number of tests, topics, questions and answers
• supports text formatting and use of images in the description of the tests, the questions and the answers
• once defined, the topics can be used alone or together for different tests
• supports both multiple-answer questions and free-answer questions
• automatically calculates the cumulative score for multiple answers
• includes a system to manually evaluate the free answers
• generates unique tests for each user by randomly selecting questions and possible answers
• supports timing for starting time and duration of the tests
• can generate PDF versions of the tests so that they can be done without using a computer
• generates reports and statistical data both in XHTML and PDF formats
• allows the customization of the format and the headers of the PDF documents
• supports the output of the test results for the final user
• sends test results to users via email
