2018极限科学研讨会（Workshop on Science at Extreme Scales: Where Big Data Meets Large-Scale Computing Tutorials）
2018 极限科学 研讨会
2017/12/20
The program opens with four days of tutorials that will provide an introduction to major themes of the entire program and the four workshops. The goal is to build a foundation for the participants of...
OPTIMAL BEAM PATTERN DESIGN FOR VERY LARGE SENSOR ARRAYS WITH SPARSE SAMPLING
OPTIMAL BEAM PATTERN DESIGN VERY LARGE SENSOR ARRAYS SPARSE SAMPLING
2015/9/29
Consider a large scale sensor array having N sensors that monitors a surveillance area. Using all sensors simultaneously may be unreasonable in terms of power consumption and data processing.For examp...
BROADBAND SENSOR LOCATION SELECTION USING CONVEX OPTIMIZATION IN VERY LARGE SCALE ARRAYS

2015/9/29
Consider a sensing system using a large number of N microphones placed in multiple dimensions to monitor a broadband acoustic field. Using all the microphones at once is impractical because of the amo...
Passive tracer in a slowly decorrelating random flow with a large mean
Passive tracer slowly decorrelating random flow large mean
2015/7/14
We consider the movement of a particle advected by a random flow of the form v + δF(x), with v ∈ Rd a constant drift, F(x) – the fluctuation – given by a zero mean, stationary random field and δ 1 s...
Noncrossing Linked Partitions and Large (3, 2)-Motzkin Paths
Noncrossing linked partition Schroder path large (3 2)-Motzkin path (3 2)-Motzkin path Schrö der number
2014/6/3
Noncrossing linked partitions arise in the study of certain transforms in free probability theory. We explore the connection between noncrossing linked partitions and (3, 2)-Motzkin paths, where a (3,...
A rough sets partitioning model for incremental mining of sequential patterns in large databases
data mining incremental mining Sequential patterns
2010/9/26
Frequent sequential patterns mining finds intresting event sequences from various real world databases under study. However, most of real world databases are subject to updations with advancement of t...
On the superimposition of heterogeneous traffic at large time scales
heterogeneous traffic scales
2010/11/24
Various empirical and theoretical studies indicate that cumulative network traffic is a Gaussian process. However, depending on whether the intensity at which sessions are initiated is large or small ...
A hypothetical answer to the question of when a sufficiently large number of elements confirm that the set is infinite
elements confirm the set is infinite
2010/11/23
We present a conjecture on integer arithmetic which implies that there is an algorithm that for each recursively enumerable set M \subseteq \mathbb{N} given by a Diophantine representation computes a...
Large time asymptotics for the Grinevich-Zakharov potentials
Large time asymptotics the Grinevich-Zakharov potentials
2010/11/23
In this article we show that the large time asymptotics for the Grinevich-Zakharov rational solutions of the Novikov-Veselov equation at positive energy (an analog of KdV in 2+1 dimensions) is given b...
Large Deviations for Random Matricial Moment Problems
Random Matricial Moment Problems math
2010/11/8
We consider the moment space $\mathcal{M}_n^{K}$ corresponding to $p \times p$ complex matrix measures defined on $K$ ($K=[0,1]$ or $K=\D$). We endow this set with the uniform law. We are mainly inte...
Lyapunov exponents of convergent Cohen-Grossberg-type BAM networks with delays and large impulses
Neural networks Delays Impulses Homeomorphism
2010/9/13
The article is concerned with the exponential convergence of a Cohen- Grossberg-type BAM network, with time-varying and distributed transmission delays and large impulses, towards a unique equilibrium...
A new computational harmonic projection algorithm for large unsymmetric generalized eigenproblems
Eigenvalue unsymmetric matrix harmonic Arnoldi
2010/9/13
The harmonic projection method can be used to find interior eigenpairs of large matrices. Given a target point or shift σ to which the needed interior eigenvalues are close, the desired interior eigen...
Large sharpening intertemporal prospect theory
Discount utility theory intertemporal choice prospect theory
2010/9/15
Prospect theory [4] of risky choices has been extended to encompass intertemporal choices [6]. Presentation of intertemporal prospect theory suffers from minor mistakes, however [2]. To clarify the th...

Sylvester matrix equations Global FOM method
2010/9/16
This paper presents equivalent forms of the Sylvester matrix equations.These equivalent forms allow us to use block linear methods for solving large Sylvester matrix equations. In each step of theses ...
In this note we prove a large deviation result for a perturbed discontinuous inhomogeneous system which complements[1].
