- Vibration Response Spectrum
- License: Freeware

This program calculates the Vibration Response Spectrum (VRS) for a base input Power Spectral Density (PSD). The base input PSD must be in terms of acceleration. The VRS uses point-by-point multiplication of the transmissibility function times the base input PSD. It is thus more accurate than Miles equation..

- Spread Spectrum Simulation Application
- License: Freeware

3SA (Spread Spectrum Simulation Application) is an interactive application that allows the user to select an input audio signal (a pre-recorded .wav file or a microphone) and "watch" as it is processed, transmitted, and received in a direct sequence spread spectrum simulation. It is intended to give the user a basic overview of DSSS by describing the individual components of a general system. The application will run in MATLAB 7, but qualities related to the user interface may not display correctly. sssa.m is the application's driver..

ZAC Browser (Zone for Autistic Children) is the first web browser developed specifically for children with autism, and autism spectrum disorders such as Asperger syndrome, pervasive developmental disorders (PDD), and PDD-NOS. Zac Browser is for children - for their enjoyment, enrichment, and freedom. Children touch it, use it, play it, interact with it, and experience independence. ZAC is the zone that will permit your child to interact directly with games (a LOT of games) and activities (focused on MANY interests) that cater specifically to kids who display the characteristics of autism spectrum disorders, like impairments in social interaction, impairments in communication, restricted interests and repetitive behavior.

- Voxengo Span x64
- License: Freeware

SPAN is a real-time 'fast Fourier transform' audio spectrum analyzer plug-in for professional music and audio production applications. For the most part it was derived from Voxengo GlissEQ dynamic parametric equalizer and reproduces its spectrum analysis functionality. SPAN provides you with a very flexible &mode& system which you can use to setup your spectrum analyzer preferences. You may specify Fourier block size in samples, FFT window overlap percentage, spectrum's visual slope. Beside that you can choose to display secondary spectrum of a desired type (e.g. real-time maximum, all-time maximum).
