Queueing Theory deals with problems where some restricted resource should be shared between competitive flow of requests. In this paper we use Queueing Theory methods to perform a quantitative analysis of a single-level single-mediator multi-agent system. In the system, several agents, coordinated by the mediator process user queries. We adopt matrix analytic methods to compute performance char...

Annotating remote sensing images is a challenging task for its labor demanding annotation process and requirement of expert knowledge, especially when images can be annotated with multiple semantic concepts (or labels). To automatically annotate these multi-label images, we introduce an approach called Multi-Label Classification based on Low Rank Representation (MLC-LRR). MLC-LRR firstly utiliz...

This work explores the spatial distribution of monsoonal flooded areas using ENVISAT C-band Advanced Synthetic Aperture Radar (ASAR) in the semi-arid region of N. Gujarat, India. The amplitude component of SAR Single Look Complex (SLC) images has been used to estimate the extent of surface and near-surface water dynamics using the mean amplitude (MA) of monsoonal (July to September) and post-mo...

The Economics & Statistics Discussion Papers are preliminary materials circulated to stimulate discussion and critical comment. The views expressed in the papers are solely the responsibility of the authors.

The famous Littlewood Conjecture states that for any two real numbers (α, β) ∈ R the value m(α, β) := inf { q · ||qα|| · ||qβ|| : q ∈ N} is equal to zero. In this paper we provide an algorithm which for given 2 > 0 checks, if the value mLC := supα,β m(α, β) is less than 2. In particular with its help we show that mLC < 1/19. We also provide a similar algorithm for p-adic counterpart of the Litt...

A brief status report on the progress of the SLC machine and two detectors is given. Invited talk presented at the Workshop on Tests of Electroweak Theories, Polarized Processes, and other Phenomena, Trieste, Italy, lo-12 June 1985 * Work supported by the Department of Energy, contract DE-AC0376SF00515.

Some properties of beamstrahlung are discussed, and plans to observe the effect at SLC by the use of Cherenkov counters are illustrated. Invited talk presented at the International Conference on Advances in Experimental Methods for Colliding Beam Physics, Stanford, California, March 9-13, 1987 * Work supported by the Department of Energy, contract DE A C 0 3 7 6 SF 00 5 15.

In this paper we survey some of the major data structures for encoding Level Of Detail (LOD) models. We classify LOD data structures according to the dimensionality of the basic structural element they represent into point-, triangle-, and tetrahedron-based data structures. Within each class we will review single-level data structures, general data structures for LOD models based on irregular m...
