Best practice benchmarking (benchmarking for short) generally refers to the pursuit by organizations of enhanced performance by learning from the successful practices of others. Comparisons of key processes which contribute to organizational success are made – with other parts of the same organization; competitors; or organizations operating comparable processes in a context which is in some wa...

in this paper two different rateless transmissionschemes are developed. in the proposed scheme, relay node candecode and forward the message to the destination if they areable to decode it, or amplify and forward the message to thedestination. based on the analysis and simulation resultsprovided in this paper, the proposed method has bettertransmission time than the scheme which only the relay ...

Best practice benchmarking (benchmarking for short) generally refers to the pursuit by organisations of enhanced performance by learning from the successful practices of others. Comparisons of processes which contribute to strategic success are made with other parts of the same organisation; competitors; or organisations operating comparable processes in a context which is in some way relevant....

one of the most important problems in the system reliability optimization is redundancy allocation problem that has been studied in different system configurations. k-out-of-n structure is a general system configuration and offers enhanced capabilities for analyzing more design problems. hence, in this paper, the redundancy allocation problem of k-out-of-n systems is studied. in the most previo...
