An Efficient ContextFree Parsing Algorithm
, 1970
"... A parsing algorithm which seems to be the most efficient general contextfree algorithm known is described. It is similar to both Knuth's LR(k) algorithm and the familiar topdown algorithm. It has a time bound proportional to n 3 (where n is the length of the string being parsed) in general; i ..."

The protection of information in computer systems
"... This tutorial paper explores the mechanics of protecting computerstored information from unauthorized use or modification. It concentrates on those architectural structureswhether hardware or softwarethat are necessary to support information protection. The paper develops in three main sectio ..."

Quantum complexity theory
 in Proc. 25th Annual ACM Symposium on Theory of Computing, ACM
, 1993
"... Abstract. In this paper we study quantum computation from a complexity theoretic viewpoint. Our first result is the existence of an efficient universal quantum Turing machine in Deutsch’s model of a quantum Turing machine (QTM) [Proc. Roy. Soc. London Ser. A, 400 (1985), pp. 97–117]. This constructi ..."

–117]. This construction is substantially more complicated than the corresponding construction for classical Turing machines (TMs); in fact, even simple primitives such as looping, branching, and composition are not straightforward in the context of quantum Turing machines. We establish how these familiar primitives can
ContextBased Vision System for Place and Object Recognition
, 2003
"... While navigating in an environment, a vision system has' to be able to recognize where it is' and what the main objects' in the scene are. In this paper we present a contextbased vision system for place and object recognition. The goal is' to identify familiar locations' (e ..."

From frequency to meaning : Vector space models of semantics
 Journal of Artificial Intelligence Research
, 2010
"... Computers understand very little of the meaning of human language. This profoundly limits our ability to give instructions to computers, the ability of computers to explain their actions to us, and the ability of computers to analyse and process text. Vector space models (VSMs) of semantics are begi ..."

are beginning to address these limits. This paper surveys the use of VSMs for semantic processing of text. We organize the literature on VSMs according to the structure of the matrix in a VSM. There are currently three broad classes of VSMs, based on term–document, word–context, and pair–pattern matrices
Ecommerce: The role of familiarity and trust
 Omega
, 2000
"... Familiarity is a precondition for trust, claims Luhmann [28: Luhmann N. Trust and power. Chichester, UK: Wiley, 1979 (translation from German)], and trust is a prerequisite of social behavior, especially regarding important decisions. This study examines this intriguing idea in the context of the E ..."

Towards a modern theory of adaptive networks: expectation and prediction
 Psychol. Rev
, 1981
"... Many adaptive neural network theories are based on neuronlike adaptive elements that can behave as single unit analogs of associative conditioning. In this article we develop a similar adaptive element, but one which is more closely in accord with the facts of animal learning theory than elements co ..."

stimulation, producing a conditioned response before the occurrence of the unconditioned stimulus. The element also is in strong agreement with the behavioral data regarding the effects of stimulus context, since it is a temporally refined extension of the RescorlaWagner model. We show by computer simulation

Multigrid For Eddy Current Computation

"... In [R. Hiptmair, Multigrid method for Maxwell's equations, SIAM J. Numer. Anal., 36 (1999), pp. 204225] a novel multigrid method for discrete H(curl; Omega)elliptic boundary value problems has been proposed. These frequently occur in computational electromagnetism, in particular in the contex ..."

This paper focuses on the analysis of those nodal multilevel decompositions of the spaces of edge finite elements that form the foundation of the multigrid method. This paper provides a significant extension of the existing theory. In particular, asymptotically uniform
