MTF Calculator calculates the Modulation Transfer Function (MTF) of an edge image stored in DICOM format and allows the contents to be copied to the clipboard or saved to a Comma-Separated Values (CSV) file.

DOFView is a "Depth of Field" Calculator. It is a small application written in C++/Qt for Window and Linux to evaluate the effect of the focal, subject distance, and the f-Number change, on the depth of field. DOFView will report near and far distance limits, hyperfocal, total DoF etc., both in textual or graphical format. A simulation of what can be seen in the camera viewfinder is also shown in 3D. The application was inspired by my Nikon D5100, even if the user can set information and use this program selecting among hundreds of compact or DSLR camera models.

This is a standalone HTML/JavaScript application with which a manager can get an estimate of the costs involved with the deploymnent of 1) a conventional network, 2) a network with OSS based servers and 3) a network with OSS based servers and desktops.

We introduce a completely visual representation based on typed Mind Maps to represent steps of calculation for a pure untyped lambda calculator, VLM.

SigLab is a signal calculator for Scilab. Its goal is to ease the analysis of signal processing simulation results. It allows to view and to manipulate monodimensional signals in a interactive and easy way.
