This includes harmonic analysis (HA), inverse filtering (IF), dynamic optimization (DO), optimal control (OC) and Z-transform (ZT). The methods are applied on simulated thermograms corresponding to time-invariant representative models of heat conduction calorimeters. The results suggest that: (1) IF and ZT are the simplest methods and give the best reconstructions of the heat power; (2) HA spends more computing time and memory space to achieve a similar quality in the thermogenesis; and (3) DO and OC, with the same expense in memory and time as HA, give much more inaccurate results when the power dissipation lasts a long time. On the other hand, it should be noted that to the present, IF and, conceptually, ZT and OC may be generalized to time-varying calorimetry.||URI:||http://hdl.handle.net/10553/48073||ISSN:||0040-6031||DOI:||10.1016/0040-6031(85)85504-0||Source:||Thermochimica Acta [ISSN 0040-6031], v. 89, p. 315-324|
