Title: | Identification and deconvolution in time-varying calorimetric systems by an optimal tracking approach | Authors: | Ortin, J. Torra, V. Thomas, G. Alvarez, L. De Rivera, M. Rodriguez |
UNESCO Clasification: | 2213 Termodinámica | Keywords: | Calorimetry | Issue Date: | 1986 | Publisher: | 0040-6031 | Journal: | Thermochimica Acta | Abstract: | Excess partial molar enthalpies of binary liquid mixtures can be accurately measured at very low concentrations by means of continuous-injection heat conduction calorimetry. This method causes evolution of the thermal properties of the calorimeter as a function of time. In this paper it is shown that identification and deconvolution of the thermal signal are equivalent problems when dealing with time-varying systems. A signal treatment analysis is proposed based upon optimal tracking, and different numerical examples, where the actual calorimeter is replaced by a discrete RC model, are presented. | URI: | http://hdl.handle.net/10553/48072 | ISSN: | 0040-6031 | DOI: | 10.1016/0040-6031(86)87020-4 | Source: | Thermochimica Acta [ISSN 0040-6031], v. 97, p. 203-213 |
