In this paper, we derive an analytical model to evaluate the effect of jointly tuning the carrier sense threshold and employing multiple data rates on the network capacity in multi-rate, multi-hop wireless networks. The proposed model characterizes the channel status within the carrier sense range of an individual transmitter. The per-node throughput attained by each transmitter is then obtaine...

For spiked population model, we investigate the large dimension N and large sample size M asymptotic behavior of the Support Vector Machine (SVM) classification method in the limit of N,M → ∞ at fixed α = M/N . We focus on the generalization performance by analytically evaluating the angle between the normal direction vectors of SVM separating hyperplane and corresponding Bayes optimal separati...

finding a representative fluid in a hydrocarbon reservoir is crucial for integrated reservoir management. in this study, a systematic approach for screening and selecting consistent fluid samples in a reservoir was developed. the model integrated quality control (qc) of well conditioning before sampling, qc of pvt data, thermodynamic modeling and compositional gradient within a reservoir. well ...

We report on the experimental demonstration of atomically thin molybdenum disulfide (MoS2)-graphene van der Waals (vdW) heterostructure nanoelectromechanical resonators with ultrawide frequency tuning. With direct electrostatic gate tuning, these vdW exhibit exceptional tunability, in general, {\Delta}f/f0 >200%, for continuously tuning same device and mode (e.g., from ~23 to ~107MHz), up = 370...

We argue about the importance of embedding the successful mechanism of Inflation in the context of a fundamental theory. We review some of the attempts in this direction made in the framework of String Theory. In particular we report on recent developments in Brane Inflation with emphasis on the fine tuning issue.
