) Marc Gyssens y University of Limburg Laks V.S. Lakshmanan z Concordia University Iyer N. Subramanian z Concordia University Abstract Tables are one of the most natural representations of reallife data. Previous tablebased data models (such as relational, nested relational, and complex objects models) capture only a limited variety of reallife tables. In this paper, we study the foundations of tabular representations of data. We propose the tabular database model for handling a broad class of natural data representations and develop tabular algebra as a language for querying and restructuring tabular data. We show that the tabular algebra is complete for a very general class of transformations and show that several languages designed for very different purposes can naturally be embedded into the tabular model. We also demonstrate the applicability of our model as a theoretical foundation for online analytical processing (OLAP), an emerging technology for complementing the r...

Abstract. Among the mostly investigated parameters for noisy channels are code size, error probability in decoding, block length; rate, capacity, reliability function; delay, complexity of coding. There are several statements about connections between these quantities. They carry names like “coding theorem”, “converse theorem ” (weak, strong,...), “direct theorem”, “capacity theorem”, “lower bound”, “upper bound”, etc. There are analogous notions for source coding.

These three lectures review the state of our understanding of electroweak interactions and the search for the agent of electroweak symmetry breaking. The themes of the lectures are (i) the electroweak theory and its experimental status, (ii) the standardmodel Higgs boson, and (iii) aspects of electroweak theory beyond the standard SU(2)L ⊗ U(1)Y model.

(SCH) projects, two of which are entering a construction phase. The design of the SCH outsert magnets is based on a CICC configuration using cable of multifilamentary Nb3Sn and Cu strands inside a stainless steel jacket cooled by forced flow supercritical helium at 4.5 K. The outsert coil design is presented along with the design criteria for the evaluation of conduit and conductor insulation components. The results of detailed finite element analysis performed for normal, quench and fault load conditions are discussed to ensure the levels of stress and strain in conduit and insulations satisfy the design criteria. The conduit evaluation of fatigue life and fatigue crack growth rate (FCGR) is performed and the results are discussed for a possible cyclic lifetime and a minimum detectable flaw size for the SCH outsert. Index Terms—CICC, finite element, hybrid magnets, mechanical design, stress analysis. I.

We examine t¯t production via vector boson fusion at high energy e + e − colliders using the effective vectorboson approximation. We show cross sections as functions of CM energy for various Higgs masses ranging from 100 GeV up to 1 TeV, and also for MH = ∞ which corresponds to the LET. We give expressions for σ(ViVj → t¯t) in the 2MW,Z / √ s = 0 approximation and show how this approximation effects the results. I.

Abstract: We systematically study the possibility of determining the spin of new particles after their discovery at the LHC. We concentrate on angular correlations in cascade decays. Motivated by constraints of electroweak precision tests and the potential of providing a Cold Dark Matter candidate, we focus on scenarios of new physics in which some discrete symmetry guarantees the existence of stable neutral particles which escape the detector. More specifically, we compare supersymmetry with another generic scenario in which new physics particles have the same spin as their Standard Model partners. A survey of possibilities of observing spin correlations in a broad range of decay channels is carried out, with interesting ones identified. Rather than confining ourselves to one “collider friendly ” benchmark point (such as SPS1a), we describe the parameter region in which any particular decay channel is effective. We conduct a more detailed study of chargino’s spin determination in the decay channel ˜q → q + ˜ C ± → q + W ± + LSP. A scan over the chargino and neutralino masses is performed. We find that as long as the spectrum is not too degenerate the prospects for spin determination in this channel are rather good
