    PsiNorm

    PsiNorm

    A norm calculator for neuropsychological tests for daily use in clinic

    Our premise when starting this project was that why do we have to dig through arrays of normative values to find the group our patient belongs to. Then proceed to manually calculate its z score and find out where it is on the percentile graph, when we could have a software that could do it for us. We weren’t able to find one in the literature. Thus came the PsiNorm. Currently only a demo for english exists, while Turkish adapted version is fully functional. If you'd like a version adapted to your patient population/language please contact us at Contact e-mail: psinormsoftware@gmail.com

    BitrateCompressionCalculator for Python

    A simple Python utility to calculate file size from bitrate.

    BitrateCompressionCalculator for Python (BCCpy) is a very simple application for calculating a file size from length and bitrate. BCCpy came about as the result of my beginning to learn Python and recreating the basic functionality of a simple VB program I wrote back in 1999. Since I was never very proficient with Visual Basic (or Applesoft BASIC for that matter); this application is very basic and could use lots of improvements. I'll implement them as I learn them. As of October 6, 2018; I have "abandoned" the project. I have actually forgotten everything I know about Python since writing this and other than adding error handlers; I really don't know how much further I could take it. I wanted to build a simple calculator, and I did.
