“…Seminal papers suggesting this approach are the one by Horak (1988) in the time domain and that by Emami-Naeini et al (1988) in the frequency domain. This passive approach has been developed lately by several researches but still is under development, see for example (Adrot and Flaus, 2008;Armengol et al, 2008;Fagarasan et al, 2004;Hamelin and Sauter, 2000;Ploix and Adrot, 2006;Puig et al, 2006;Rambeaux, 2000;Sainz et al, 2002). This approach has also been integrated with qualitative reasoning tools (coming from the AI community), see, e.g., the tools CA∼EN (Travé-Massuyes et al, 2001;Escobet et al, 2001), SQualTrack (Armengol et al, 2008) or MOSES (Rinner and Weiss, 2004).…”
