A promising way to capture the characteristics of changing traffic is to extract significant flow clusters in traffic. However, clustering flows by 5-tuple requires flow matching in huge flow attribute spaces, and thus, is difficult to perform on the fly. We propose an efficient yet flexible flow aggregation technique for monitoring the dynamics of network traffic. Our scheme employs twostage f...

Efficient indexing support is essential to allow content-based image and video databases using similaritybased retrieval to scale to large databases (tens of thousands up to millions of images). In this paper, we take an in depth look at this problem. One of the major difficulties in solving this problem is the high dimension (6-100) of the feature vectors that are used to represent objects. We...

The aim of the present work is to introduce the concept of $lambda _{r}$-almost convergence of sequences. We define the spaces $fleft( lambda _{r}right) $ and $f_{0}left( lambda _{r}right) $ of $ lambda _{r}$-almost convergent and $lambda _{r}$-almost null sequences. We investigate some inclusion relations concerning those spaces with examples and we determine the $beta $- and $gamma $-duals of...

Consider an agent who enters a financial market on day t = 0 with an initial capital amount x. He invests this amount on stocks and the money market, and by day t = τ , has generated a wealth W . He is given a convex class of probability measures or scenarios and a real-valued floor corresponding to each scenario. The agent faces the constraints that the expectation of W under each scenario mus...

SUMMARY ClaNC (classification to nearest centroids) is a simple and an accurate method for classifying microarrays. This document introduces a point-and-click interface to the ClaNC methodology. The software is available as an R package. AVAILABILITY ClaNC is freely available from http://students.washington.edu/adabney/clanc

L1521E seems unique among starless cores. It stands out in a distribution of a ratio (R) that we define to asses core evolution, and which compares the emission of the easily-depleted C 18 O molecule with that of the hard to deplete, late-time species N 2 H +. While all cores we have studied so far have R ratio lower than 1, L1521E has an R value of 3.4, which is 8 times the mean of the other c...

Factorial experiments are widely used in industrial experimentation and other fields. Whenever a factorial experiment is not designed as a full factorial but as a – regular or non-regular – fraction thereof, choice between competing designs and interpretation of experimental results should take into consideration how the experimental plan will confound experimental effects. This article propose...

Dragomir Tsonev (UFAM, Manaus) Title: ON THE SPECTRA OF GEOMETRIC OPERATORS EVOLVING WITH GEOMETRIC FLOWS Abstract: In this work we generalise various recent results on the evolution and monotonicity of the eigenvalues of certain geometric operators under specified geometric flows. Given a compact Riemannian manifold (M, g(t)) and a smooth function η ∈ C(M) we consider the family of operators∆−...

The paper presents an experiment on spatial planning in 2D maze-like environments in which participants had to build and execute on-line a plan to reach a target. The experiment manipulated three factors: type of instructions (two levels), number of obstacles in the mazes (four levels), and length of the minimum path to the target (three levels). The instructions were conceived to vary the impo...
