The Thick Level-Set model for dynamic fragmentation

Coupling local and non-local damage evolutions with the Thick Level Set model

It is well known that damage evolution models requires a length to avoid spurious localization. We gather these type of models under the name “non-local damage models”. In fact, non-locality is strictly needed only when the stress-strain curve starts to have a negative slope. Before this point, local models may be used. For instance, when damage exhibits some hardening, the stress-strain curve ...

Dynamic workflow model fragmentation for distributed execution

Workflow fragments are partitions of workflow model, and workflow model fragmentation is to partition a workflow model into fragments, which can be manipulated by multiple workflow servers. In this paper a novel dynamic workflow model fragmentation algorithm is proposed. Based on the well-known Petri net formalism, this algorithm partitioned the centralized process model into fragments step by ...

the use of appropriate madm model for ranking the vendors of mci equipments using fuzzy approach

abstract nowadays, the science of decision making has been paid to more attention due to the complexity of the problems of suppliers selection. as known, one of the efficient tools in economic and human resources development is the extension of communication networks in developing countries. so, the proper selection of suppliers of tc equipments is of concern very much. in this study, a ...
