About the author
My name is Alfredo Accattatis. I have always loved electronics and software, and since 1990 I have worked in private and public organisations as a software engineer, designer and developer. My experience includes embedded systems based on DSPs and microcontrollers, PC applications, avionic computers and IBM mainframes, using C, C++, Object Pascal, MATLAB, Ada, REXX and several assembly languages.
I started developing Visual Analyser in 2002, in my free time and simply for the pleasure of creating it, applying my experience in digital signal processing and numerical computation. VA is written entirely in C++Builder and has always been distributed free of charge.
Why VA remains freeware
I considered a commercial edition several times. However, keeping VA free created extraordinary academic, professional, cultural and human opportunities. Since I have a primary job, Visual Analyser has remained my space for freedom, research and experimentation. It will therefore remain freeware.
University, research and teaching
I collaborated with the University of Rome Tor Vergata, where I completed a PhD within a research group devoted to signal and image measurements and processing. I am particularly grateful to Professor Roberto Lojacono and Marcello Salmeri for their confidence and support.
Academic work contributed directly to VA, especially to impedance measurement and the scientific validation of its algorithms. For more than a decade I have also taught computer science as an adjunct professor in Mechanical and Energy Engineering programmes at the University of Rome Tor Vergata, publishing several textbooks for my students.
Other interests
My work also includes photovoltaic systems, electric drives and electric mobility. These interests led to the book Climate Change (and possible solutions), available in English and Italian, and to SolarPatrol, a monitoring application for photovoltaic systems using Voltronic inverters.
Why “SillanumSoft”?
Sillanum is the Latin name of Scigliano, a town in Calabria to which I feel deeply attached. SillanumSoft was the name I once imagined for a software company and later became the name under which I collect my personal projects.
