If we want to dump all heap entries with their corresponding stack traces we can use !heap -k -h <heap address>. If we know that some access violations were reported in the event log before (not necessarily for the same PID) we might suspect that one of threads had been terminated due to some reason. If we run the program...

Software can be considered as models of real or imagined systems which may be models themselves. The latter I call modeling expectations and any ob- served deviations in structure and behavior between the model and the system I call software defects which can be functional failures, error messages, crashes or hangs (bold line on diagrams below):. What are software requirements?...

In Proceedings of the Royal Society of London Ser. While, initially, the incorporation of strain softening in constitutive equations was considered to be a straightforward exercise, it soon appeared that the use of strain-softening models led to an excessive dependency of the solution on the discretisation in numerical analyses. However, it was demonstrated that the underlying cause was the local...

The description of the complex inelastic material behaviour is accomplished by coupling the elasto- viscoplastic constitutive model, discussed by Peri´ c with a ductile damage evolution law, introduced by Ladev` eze &. The evolution of the damage internal variable includes the important effect of micro-crack closure, which may dramatically decrease the rate of damage growth under compression [3]. The theoretical...
