“…For the development of these simulations, Java is currently the only real possibility for providing a wholly independent hardware platform. (Carlson et al, 1996;Chatterjee et al, 1997;Crutchfield and Wilson, 1998;Alfonseca et al, 1999;Salazar-Silva et al, 1999;Alfonseca and Lara, 2001;Torres et al, 2001), although there is some study on the viability of using multimedia tools such as Macromedia Flash for the simulation of real processes (Planas et al, 2001). There are also researchers who, although working in local mode, separate the engine and interface (Esquembre et al, 1996;Schmid, 1997;Schmid, 1999;Schmid, 2000;Copinga et al, 2000), i.e., the interface is on an HTML page whilst the calculation engine is outside the navigator.…”
