In this paper, we present SnipSuggest, a system that provides onthe-go, context-aware assistance in the SQL composition process. SnipSuggest aims to help the increasing population of non-expert database users, who need to perform complex analysis on their large-scale datasets, but have difficulty writing SQL queries. As a user types a query, SnipSuggest recommends possible additions to various ...

Das hier vorgestellte Verfahren ermöglicht die Analyse der Data Provenance von beliebigen SQL-Queries. Von der ebenfalls hier skizzierten Implementierung des Verfahrens werden unter anderem unterstützt: Subqueries, Aggregierungen, rekursive Queries und Window Functions. Eingabequeries werden zunächst in eine imperative Programmiersprache übersetzt. Der Programmcode wird mit einem neuen Verfahre...

An iterative time-variant filtering based on the discrete Gabor transform (DGT) has been recently proposed by the authors. In this correspondence, we present a proof of the convergence of the iterative algorithm under a sufficient condition on the analysis and synthesis window functions of the DGT. In the meantime, we show that the iterative algorithm refines the least squares solution.

This paper is focused on an interdisciplinary meeting between psychology and philosophy (personality and Weltanschauung), resulted in a synthetic investigative instrument – a questionnaire, also fast and key-oriented towards personality’s resorts, values and motivation, showed in attitudes and behaviors. I consider it as a welcome systemic rough guide concerning the subject’s frame of reference...

Might psychology someday be reduced to (= exhaustively explained by) computational neurobiology? Many still say no. We approach this question through a brief survey of some prominent intertheoretic reductions drawn from our scientific history. A general charactITization of reduction is constructed from these, and some important philosophical and methodological lessons are drawn. The five most p...

Abstract We study the genuine tripartite entanglement (GTE), one-tangle and two-tangle of W state fermionic fields in background a Schwarzschild black hole. find that, with increase Hawking temperature, GTE first decreases then tends to zero, while GHZ freezes. also that effect can completely destroy state, freezing phenomenon appears growth temperature. These results are helpful guide us selec...

Diffusible signals in plants spread RNA silencing from tissue to tissue over both short and long distances, but how does RNA interference in plants spread over long distances? In a recent paper, Molnar et al. (2010) observe that 24 nucleotide small RNAs in the model plant Arabidopsis thaliana are transported in phloem between shoots and roots and once at their destinations have the ability to d...

Efficient use of limited computational resources is essential to intelligence. Selecting computations optimally according to rational metareasoning would achieve this, but rational metareasoning is computationally intractable. Inspired by psychology and neuroscience, we propose the first learning algorithm for approximating the optimal selection of computations. We derive a general, sample-effi...
