RSS asymptoticThe Evil of Superefficiency
White Paper We point out that for any given parameter estimator there exist other estimators which have strictly lower asymptotic variance and hence are statistically more efficient than the former. In particular, if the estimator was statistically efficient... [03 Jul 2008]
Bayesian Network Management
White Paper We also present an asymptotic formula for the predictive probability of ruin (for a random walk with positive drift) for large initial capital and large number of past observations. We formulate some general network (and risk) management problems... [10 Apr 2008]
Parallel Processing Across Neural Systems: Implications for a Multiple Memory System Hypothesis
White Paper A comparison is made between hippocampal and striatal neural correlates with behavior during asymptotic performance of spatial and response maze tasks. A common conceptualization of the organization of memory systems in brain is that different... [19 Mar 2008]
Parallel Processing in Visual Search Asymmetry
White Paper Asymptotic search accuracies and display size effects were consistent with a signal-detection analysis, with lower variance encoding of Cs than Os. The difficulty of visual search may depend on assignment of the same visual elements as targets and... [19 Mar 2008]
A Positive Systems Model of TCP-Like Congestion Control: Asymptotic Results
White Paper This paper studies communication networks that employ drop-tail queueing and Additive-Increase Multiplicative-Decrease (AIMD) congestion control algorithms. It shows that the theory of nonnegative matrices may be employed to model such networks. [14 Jan 2008]
Multifractality in TCP/IP Traffic: The Case Against
White Paper The discovery of Long-Range Dependence (a kind of asymptotic fractal scaling) in packet data from LANs and WANs was followed by further work detailing evidence for multifractal behaviour in TCP/IP traffic in WANs. [14 Jan 2008]
TCP Throughput Analysis Under Transmission Error and Congestion Losses
White Paper For the case of Poisson transmission errors, it shows that the asymptotic model where the population tends to infinity leads to a well defined and tractable dynamical system. This paper analyzes the performance of a large population of long lived... [14 Jan 2008]
Stability Analysis of Some Classes of TCP/AQM Networks
White Paper Necessary and sufficient conditions for the asymptotic stability of the linearized models are obtained. The local stability analysis of some classes of nonlinear time-delay systems, encountered as fluid flow models for TCP/AQM networks, is addressed. [26 Dec 2007]
Fractal Analysis of Intraflow Unidirectional Delay Over W-LAN and W-WAN Environments
White Paper The correlation structures of packet delay on bulk TCP data path and UDP flows follow asymptotic decay while Hurst exponent estimates suggest from moderate to strong intensity (H ? This paper has analysed unidirectional delay traces of a diverse... [05 Dec 2007]
On TCP and Self-Similar Traffic
White Paper A careful reassessment of their data analysis shows that this claim is not justified and suggests that the TCP trace in question is not consistent with (asymptotic second-order) self-similarity or Long-Range Dependence (LRD). [06 Nov 2007]
Local Stability of FAST TCP
White Paper When feedback delay is present, a sufficient condition is derived for local asymptotic stability for the case of a single link. The stability of FAST TCP is studied in this paper based on a discrete-time model. [30 Oct 2007]
Nonlinear Stability Analysis for a Class of TCP/AQM Networks
White Paper In the more realistic case of delayed feedback, local asymptotic stability and quantify a region of attraction is established. Recent work has shown the benefit of using proportional feedback in TCP/AQM networks. [29 Oct 2007]
Impact of Interference on Multi-Hop Wireless Network Performance
White Paper Unlike previous work that has focused on computing asymptotic performance bounds under assumptions of homogeneity or randomness in the network topology and/or workload, the authors work with any given network and workload specified as inputs. [31 Aug 2007]
A Study of the Coverage of Large-Scale Sensor Networks
White Paper The paper characterizes the asymptotic behavior of the coverage measures for a variety of sensor network scenarios. This paper studies the coverage properties of large-scale sensor networks. Three coverage measures are defined to characterize the... [23 Aug 2007]
