Average Link Rate Analysis over Finite Time Horizon in a Wireless Network
Instantaneous and ergodic rates are two of the most commonly used metrics to characterize throughput of wireless networks. Roughly speaking, the former characterizes the rate achievable in a given time slot, whereas the latter is useful in characterizing average rate achievable over a long time …

Rate analysis of the θ13 neutrino mixing angle for the Daya Bay Reactor Neutrino Experiment
We perform a rate analysis of the neutrino mixing angle θ13 for the Daya Bay Reactor Neutrino Experiment. The data were collected from December 24, 2011, to May 11, 2012, during a period of data acquisition when six antineutrino detectors were deployed. After accounting for backgrounds and detector …

Mutation Rate Analysis of the Human Mitochondrial D-loop and its Implications for Forensic Identity Testing
… facilitate mitochondrial DNA (mtDNA) sequence analysis for human identity testing, a better understanding of its mutation rate is needed. Prior to the middle 1990's the mutation rate applied to a forensic or evolutionary analysis was determined by phylogenetic means, This method involved …

Application of Multivariable Control Theory to Improve Steering and Propulsion Control of a Containership
… at the plant input. Also, using robustness analysis and a numerically determined uncertainty bound, it is shown that the maximum allowable uncertainty in the ship hydrodynamic coefficients before a potential for closed loop instability exists is 6.5 percent. The multivariable …
