A Bayesian reliability growth model is presented which includes special features designed to reproduce special properties of the growth in reliability of an item of computer software (program). The model treats the situation where the program is sufficiently complete to work for continuous time peri...

The situation where dimer formation and splitting is possible in irradiated RNA molecules is considered. The equilibrium distribution of dimers ( i.e. the distribution after a long time) is obtained, in particular the average number of dimmers as a function of molecule length and reaction rates. The...

The reaction kinetics of irradiated RNA molecules is analysed for the cases when dimer formation (not splitting) and hydration of uracil residues take place. After a sufficient time has elapsed, such molecules consist entirely of dimers and hydrated sites, at which time it is of interest to know the...
