Logical Events and ECA Rules

by Mikael Berndtsson, Brian Lings , 1995
"... This paper presents an approach to support event-condition-action rules and logical events in an object-oriented environment. Previous approaches in active object-oriented databases support either traditional event-condition-action rules or logical events. We see the need to integrate these two conc ..."

Parallel Rule Processing in a Distributed Object Environment

by Minsoo Lee , Stanley Y. W. Su, Herman Lam
"... The use of rules is becoming a major trend for adding active capability to passive systems. Although adding the rule processing capability into a system is highly desirable, the effect on performance can be detrimental. To solve the performance problem that is introduced by the overhead of rule proc ..."

specification language and its accompanying GUI tool for specifying events and various parallel rule execution structures associated with distributed objects. Different from the traditional event-condition-action rules used in the existing active databases, the rule model used in this work separates event

Mylopoulos: Supporting Distributed Event-Condition-Action Rules in a Multidatabase Environment

by Vasiliki Kantere, Iluju Kiringa, John Mylopoulos - Int. J. Cooperative Inf. Syst , 2007
"... We describe a mechanism based on distributed Event-Condition-Action (ECA) rules that supports data coordination in a multidatabase setting. The proposed mechanism includes an ECA rule language and a rule execution engine that transforms rules when they are first posted, and then coordinates their ex ..."

Theory and Practice of Constraint Handling Rules

by Thom Frühwirth , 1998
"... Constraint Handling Rules (CHR) are our proposal to allow more flexibility and application-oriented customization of constraint systems. CHR are a declarative language extension especially designed for writing user-defined constraints. CHR are essentially a committed-choice language consisting of mu ..."

Bylund, Francesco Denozza, Yoshikata Fukui, Zvi Griliches, Oliver Hart, Martin Hellwig, James Hines, Louis Kaplow, Raghu Rajan, Roberta Romano, Rolf Skog, Eddy Wymeersch, Luigi Zingales - Journal of Political Economy , 1998
"... This paper examines legal rules covering protection of corporate shareholders and creditors, the origin of these rules, and the qual-ity of their enforcement in 49 countries. The results show that common-law countries generally have the strongest, and French-civil-law countries the weakest, legal pr ..."

The science of emotional intelligence

by Peter Salovey, John D. Mayer , 2005
"... This article presents a framework for emotiolllJl intelligenCl!, a set of skills hypothesized to contribute to the accurate appraisal and expression of emotion in oneself and in others, the effective regulation of emotion in self and others, and the use of feelings to motivate, plan, and achieve in ..."

in terms? One tradition in Western thought has viewed emotions as disorganized interruptions of mental activity, so potentially disruptive that they must be controlled. Writing in the first century B.C., Publilius Syrus stated, "Rule your feelings, lest your feelings rule you " [1}.

Investor psychology and security market under- and overreactions

by Kent Daniel, David Hirshleifer - Journal of Finance , 1998
"... We propose a theory of securities market under- and overreactions based on two well-known psychological biases: investor overconfidence about the precision of private information; and biased self-attribution, which causes asymmetric shifts in investors ’ confidence as a function of their investment ..."

Event-Condition-Action Rule Languages for the Semantic Web

by George Papamarkos, Alexandra Poulovassilis, Ra Poulovassilis, Peter T. Wood - In: Workshop on Semantic Web and Databases , 2003
"... The Semantic Web is based on XML and RDF as its fundamental standards for exchanging and storing information on the World Wide Web. Event-condition-action (ECA) rules are a natural candidate for supporting reactive functionality on XML or RDF repositories. In this paper we describe a language fo ..."

Fading relay channels: Performance limits and space-time signal design

by Rohit U. Nabar, Helmut Bölcskei, Felix W. Kneubühler - IEEE J. SELECT. AREAS COMMUN , 2004
"... Cooperative diversity is a transmission technique where multiple terminals pool their resources to form a virtual antenna array that realizes spatial diversity gain in a distributed fashion. In this paper, we examine the basic building block of cooperative diversity systems, a simple fading relay ch ..."

of the paper is devoted to (distributed) space-time code design for fading relay channels operating in the AF mode. We show that the corresponding code design criteria consist of the traditional rank and determinant criteria for the case of co-located antennas as well as appropriate power control rules

Optimality Theory
