Realization of an adaptive method of simulating the process of temperature change of a cadaver on a microcomputer

Programme based on mathematical model of the process of dead body temperature changing was developed for estimation of postmortem interval. Automatic retrieval of problem solution was performed on programmable microcalculators of "Electronica MK-61" type using adaptive approach. Diagnostical accuracy in case of dead body being preserved in permanent cooling conditions is +/- 3%.     

The methodological aspects of establishing the time of death]

Methodological analysis of essence of problem concerning postmortem interval estimation is given. The authors present the most promising ways of scientific research on this problem and possibilities of practical use of results of scientific research. The general methods of postmortem interval estimation including wired-in analogy (criterial) method and methods of modelling postmortal processes (mathematical and physical) are analysed. Graph of logical structures of modes of postmortem interval estimation and means of their realization is given.     

A diagnostic program for estimating the time of death using microcalculators MK-61 and B3-34

The programme design is based on the process of changes in dead body temperature. Specific features of the process of changes in temperature values of a dead body are characterized by a parameter which involves process sample obtained by temperature measurements in diagnostical area of a cadaver at the accident scene during 1 hour. Programme provides for estimation of postmortem interval within the first 60 h after death occurrence. Diagnostical deviations don't exceed +/- 3% as compared to the real time of death.
