Variable 4 is a multichannel sound installation that uses meteorological sensors and a multi-layered array of algorithmic processes to transform weather data into musical patterns in real time. This paper describes the work in detail, outlining its historical context, systems infrastructure and installation specifics. The piece is discussed in relation to sonification and environmental installa...

This work deals with the observer siting problem in terrains represented by digital elevation matrices. This problem consists in minimize the number of observers needed to see (or cover) a given percentage of a terrain. Two heuristics are proposed to solve this problem and these heuristics are compared with a method described in literature. Tests show that the proposed heuristics generate solut...
