Dr. Mario Stipcevic is a higher asistant at the Ruder Boškovic Institute in Zagreb. He made his PhD in particle physics working at the RD3 experiment at CERN, Geneve. In 1999 he started, together with his collegues, to build a scientific experiment for search for heavy photons at the R.B. Institute in Zagreb. For purpose of automated controll of the system, a WEB application was built, which later evolved into a system for general control and monitoring of processes. In 2001 he started a group for building a pilot cluster computer at the R.B. Institutute. Stipcevic is author and coauthor of numerous articles in the field of electronics and particle physics and has contributed several free-software programs to the Internet community.
