in this paper, a novel method for ranking of fuzzy numbers are proposed. in this method, decision maker is defined based on the center of mass at some cuts of a pair of fuzzy numbers in discreet version and center of mass on all of cuts of a pair of fuzzy numbers in continuous version. our method can rank more than two fuzzy numbers simultaneously. also, some properties of methods are described...

Solving Practical Problems in Datacenter Networks

The National Climatic Data Center (NCDC) currently receives NEXRAD Doppler radar level II (base) data from 120 NWS, 12 FAA and 26 DOD sites on 8mm tape or online. The NCDC is partnering with the NWS Radar Operations Center, the National Severe Storms Lab, the University of Oklahoma and UNIDATA on the Collaborative Radar Acquisition Field Test (CRAFT) project (Droegemeier et al. 2002).

Achieving Consistent Latencies in Datacenter Networks

xiii Zusammenfassung xvii Acknowledgements xxi

In this work, we investigate mechanisms to ensure that a shared data center can operate within a power budget, while optimizing a global objective function(e.g., maximize the overall revenue earned by the provider). We present the BrownMap methodology that is able to ensure that data centers can deal both with outages that reduce the available power or with surges in workload. BrownMap uses aut...
