چکیده
Replication of data has been used for enhancing its availability in the presence offailures in distributed systems. Data can be replicated with greater ease thangeneralized objects. We review some of the techniques used to replicate objects forresilience in distributed operating systems. Wediscuss the problems associated with the replication of objects and presentascheme of replicated actions and replicated objects, using a paradigm we call PETs(parallel execution threads). The PET scheme not only exploits the high availabilityof replicated objects but also tolerates site failures that happen while an action isexecuting. We show how this scheme can be implemented in a distributed objectbased system, and use the Clouds operating system as an example testbed.

The evolution of the crack growthspeed in a thin, buckled strip delamina-tion is studied and two approximate solu-tions are presented. The quasi-dynamicanalysis assumes that the deflection ofthe delaminated layer is represented bythe static postbuckling solution for thecurrent delamination length.
