Belief Conditioning Rules for Classic Belief Functions
Daniel, Milan
2009 - English
The classic belief conditioning rules (BCRs) and DSm BCRs applied to classic belief functions are briefly recalled in the contribution. A general idea of belief conditioning by a given evidence is analysed and a new plain BCR is presented. This rule is compared with both the classic and the DSm BCRs. Finally, general formulas for described BCRs and a new general BCR are presented and defined. V příspěvku jsou stručně připomenuta klasická podmiňovací pravidla a DSm podmiňovací pravidla aplikovaná na klasické domněnkové funkce. Je zde prezentována a analyzována myšlenka podmiňování danou evidencí. Je prezentováno nové 'plain' podmiňovací pravidlo. Nové pravidlo je porovnáváno jak s klasickými, tak s DSm podmiňovacími pravidly. Závěrem jsou představeny obecné formule pro popisovaná podmiňovací pravidla a definováno nové obecné podmiňovací pravidlo.

Language for reconfiguring runtime infrastructure of component-based systems
Malohlava, M.; Bureš, Tomáš
2008 - English
A component system is not only composed of a model but also of an execution environment which is able to instantiate components described by the model. However, the execution environment reflecting a complex component model and its changes at runtime is a non-trivial and error-prone application. Hence it is beneficial to simplify and conceptualize the execution environment by having a simple way of describing component compositions and reconfigurations. In this paper we propose a minimalistic language which describes the composition of the component-based system’s infrastructure in a procedural way and thus reduces the execution environment basically to a simple language interpreter. Komponentový systém kromě modelu sestává i z exekučního prostředí, jež má za úkol instanciovat komponenty popsané modelem. Takové exekuční prostředí, jež odráží komplexní komponentový model a změny za běhu, je ale sama o sobě netriviální aplikace. Je proto výhodné zjednodušit a konceptualizovat exekuční prostředí s pomocí jednoduchého popisu seskládávaní komponent a jejich rekonfigurací. V tomto článku navrhujeme minimalistický jazyk pro procedurální popis seskládávaní komponent, díky němuž je pak možno redukovat exekuční prostředí téměř na jednoduchý interpretr navrhovaného jazyka.
