High-Rate Analysis of Symmetric L-Channel Multiple Description Coding

Guoqiang Zhang, Jan Ostergaard, Janusz Klejsa, W. Bastiaan Kleijn
2011 IEEE Transactions on Communications  
This paper studies the tight rate-distortion bound for L-channel symmetric multiple-description coding of a scalar Gaussian source with two levels of receivers.  ...  Using this property, we analyze the asymptotic behavior of a practical multiple-description lattice vector quantizer (MDLVQ).  ...  In particular in [9] , Wang and Viswanath addressed the symmetric descriptions scenario with two levels of receivers. Each of the first-level receivers obtains κ of the L descriptions (κ < L).  ...

On the scaling of non-asymptotic capacity in multi-access networks with bursty traffic

Florin Ciucu
2011 2011 IEEE International Symposium on Information Theory Proceedings  
The practicality of available (throughput) capacity results in multi-access networks, which dispense with coding schemes, is often questioned for several reasons including 1) the underlying asymptotic  ...  The explicit and closed-form nature of the results enable the investigation of the impact of burstiness on non-asymptotic network capacity.  ...  scenarios with bursty data sources.  ...

Several descriptive traits based on simulated longitudinal data from the Genetic Analysis Workshop 13 (GAW13) were generated, and linkage analyses were performed for these traits.  ...  We found that using longitudinal traits based on multiple follow-ups may not be more powerful than using cross-sectional traits for genetic linkage analysis.  ...  Acknowledgments Some of the results of this paper were obtained by using the S.A.G.E. package of genetic epidemilogy software, which is supported by a U.S.  ...

Atushi Tanaka
2006 Physical Review A. Atomic, Molecular, and Optical Physics  
The evaluation of a tunneling tail by the Herman-Kluk method, which is a quasiclassical way to compute quantum dynamics, is examined by asymptotic analysis.  ...  In the deeper part, it is shown that the asymptotic equivalence breaks down, due to the emergence of unusual "tunneling trajectory", which is an artifact of the Herman-Kluk method.  ...  Acknowledgments This work is partially supported by the Grant-in-Aid for Young Scientists (B) (No. 15740241) from the Ministry of Education, Culture, Sports, Science and Technology, Japan.  ...
