PlusV
An Open Source alternative to SBR (Spectral band replication)
What is PlusV? With traditional MP3, a typical Near CD Quality audio file has been encoded with a data rate of 128 kbits/s. While this is ok for people with big hard disks and fast Internet connections, this data speed has clearly been a bottleneck for people using modems or storing their music into 32 or 64 MB portable player FLASH cards. PlusV is a brand new audio compression enhancement technology that allows audio files to be compressed in as little as 64 or even 48 kbits/s. PlusV... -

easy-dhpsf
GUI for fitting 3D single-molecule images using the double-helix PSF
This package of MATLAB routines with accompanying GUI allows scientific users to measure the 3D location of single molecules when using the double-helix point spread function (DH-PSF) widefield microscope. Version 2 also includes code that facilitates combining localization data from two spectral channels using a locally-weighted quadratic 3D registration function Features - Double-Gaussian estimator is calibrated via an axial scan of bright immobile fluorescent emitters (e.g. beads) - DH localization is performed through template matching and subsequent double Gaussian fitting - Tiff stacks of SM images are analyzed using template matching followed by double-Gaussian fitting to extract estimates of the molecule positions - Two spectral channels are registered by generating a locally-weighted quadratic mapping function from control point pairs -

JSpecView Project
Spectroscopy Viewer
The JSpecView Project initially provided JAVA applets for the display of JCAMP-DX and AnIML/CML spectral files. The source and binary files are available via the Code (sourceforge SVN) and Files menu options. See the WIKI pages (Hosted Apps) for more detail. Beginning September 2018 all code changes are being handled via the Jmol Sourceforge page. The codes has been fully merged and JSmol the JavaScript/HTML5 version of Jmol now includes the non-Java version of JSpecView. -

Radiance
Highly accurate ray-tracing software system for UNIX computers
...Radiance is superior to simpler lighting calculation and rendering tools in that there are no limitations on the geometry or the materials that may be simulated. Scene geometry, materials, luminaires, time, date and sky conditions (for daylight calculations) are specified; spectral radiance (ie. luminance + color), irradiance (illuminance + color) and glare indices are calculated. Simulation results may be displayed as color images, numerical values and contour plots. Radiance is useful for architects and engineers in predicting illumination, visual quality and appearance of innovative design spaces; and for researchers in evaluating new lighting and daylighting technologies. -
