For a generic gauge-invariant correlator < Q[Aµ]>A, we reformulate the standard D = 4 Yang-Mills theory as a renormalizable system of two interacting fields aµ and Bµ which faithfully represent high- and low-energy degrees of freedom of the single gauge field Aµ in the original formulation

Abstract—The paper discusses the use of decision trees for probability-based ranking. Emphasis is placed on ranking problems in question answering, where the frequency of correct candidates is very low but a single correct answer at one of the top ranks is often sufficient. Since existing tree

A plastic robot arm design and manufacturing scenario is presented to demonstrate the application of this methodology and its effectiveness for solving a complex design for manufacturing problem in a streamlined manner, with minimal expensive iterations.

metrics have the potential to perform better than the conventional Euclidean metric for classification. Moreover, in the case of heterogenous sensors, the learned multiple metrics can be quite different, which are adapted to each type of sensor. By learning the multiple metrics jointly within a single

Abstract Supporting database schema evolution repre-sents a long-standing challenge of practical and theoretical importance for modern information systems. In this paper, we describe techniques and systems for automating the critical tasks of migrating the database and rewriting the legacy applications. In addition to labor saving, the ben-efits delivered by these advances are many and include reliable prediction of outcome, minimization of downtime, system-produced documentation, and support for archiving, historical queries, and provenance. The PRISM/PRISM++ system delivers these benefits, by solving the difficult prob-lem of automating the migration of databases and the rewrit-ing of queries and updates. In this paper, we present the PRISM/PRISM++ system and the novel technology that made it possible. In particular, we focus on the difficult and previously unsolved problem of supporting legacy queries and updates under schema and integrity constraints evolution. The PRISM/PRISM++ approach consists in providing the users with a set of SQL-based Schema Modification Opera-tors (SMOs), which describe how the tables in the old schema are modified into those in the new schema. In order to sup-port updates, SMOs are extended with integrity constraints

ABSTRACT. We consider a classical system of point particles interacting by means of a short range potential. We prove that, in the low–density (Boltzmann–Grad) limit, the system behaves, for short times, as predicted by the associated Boltzmann equation. This is a revisitation and an extension of the thesis of King [9] (appeared after the well known result of Lanford [10] for hard spheres) and of a recent paper by Gallagher et al [5]. Our analysis applies to any stable and smooth potential. In the case of repulsive potentials

iii The aim of this work is focused on designing a new generalized loading approach for Uniform Linear Array (ULA). This method achieves robust adaptive beamforming against direction-of-arrival (DOA) mismatches by shaping the directional response of the adaptive Uniform Linear Array. To achieve this purpose, we consider an ULA with N sensors, which are located at half wavelength spacing. The desired spatial signal impinges from a specific direction, such that the presumed direction has a mismatch with the true direction. Furthermore we assume that the desired signal components are present in the beamformer training data snapshots and that the data sample size is limited. Therefore, we desire to develop a robust adaptive beamformer to improve the performance against inaccuracies caused by limited sample size and the look direction mismatch by shaping the directional response of the array. The ability of the directional response shaping (DRS) will follow the modified
