Language of Preference Formulae
Nedbal, Radim
2012 - anglický
There is a need for handling preferences in relational query languages that arises naturally in real-world applications dealing with possible choices generated by the current state of the world captured in the relational data model. To address this problem, we propose a fully declarative language for encoding preferences conditional on the current state of the world represented as a relation database instance. Being based purely on the qualitative type of information about the preference model, the language is intuitive and leads to a exible approach for specifying the most desirable choices of autonomous systems that act on behalf of their designers. Throughout the paper, we use an example of a control support system for a bank surveillance to motivate the need for our framework and to illustrate it.

Classification Methods for Brain-Computer Interface
Bobrov, P.; Frolov, A. A.; Húsek, Dušan
2011 - anglický
The performance of four classifiers for Brain Computer Interface (BCI) systems based on multichannel EEG recordings is tested in this work. The classifiers are designed to distinguish EEG patterns corresponding to performance of several mental tasks. It is shown that relatively simple classifiers based on the Bayesian approach are comparable in classification accuracy with more sophisticated classifiers based on Common Spatial Patterns and Common Tensor Discriminant Analysis

Mode Change in Real-time Component Systems - Suitable Form of Run-Time Variability in Resource Constrained Environments
Outlý, M.; Pop, T.; Bureš, Tomáš
2011 - anglický
The document describes and examines possibilities of run-time vari- ability in real-time embedded component systems. Namely it formally describes sup- port of operating modes. The report introduces a recon guration mechanism based on properties and relations between them. The mechanism is designed to facilitate a straight forward modeling of operating modes and recon guration rules and pre- serves re-usability of assembled components. The report also presents a realization of the mechanism suitable for the domain of embedded real-time systems.

Morphisms of Dempster's Semigroup: A Revision and Interpretation
Daniel, Milan
2011 - anglický
Analyzing three new approaches to interpretation, definition, and measurement of conflicts of belief Functions (BFs), we previously observed a possibility of expression of a BF Bel as Dempster's sum of non-conflicting BF Bel0 with the same plausibility decisional support as the original BF Bel has and of indecisive BF BelS which does not prefer any of the elements of frame of discernment. Based on this observation, the theory of homomorphisms of Dempster's semigroup (the algebra of non-extremal BFs on 2-element frame of discernment with Dempster's rule as its binary operation) is updated in the present contribution. New homomorphisms are introduced; their interpretation and relation to the original ones are presented.

Ferdinand Project Middleware List
Keznikl, Jaroslav; Malohlava, M.; Marek, L.; Tůma, P.
2011 - anglický
The purpose of this report is to provide an overview of the middleware environments used in the Ferdinand project. The environment selection has been based on four major criteria: Implementation available in source form (necessary for investigating potential performance anomalies). Multiple comparable implementations available (necessary for generalizing performance evaluation results). Environment widely in use in contemporary applications. Realistic workloads available. This report is intended to serve as a (continuously updated) reference for project partners, care is therefore taken to include links to web sites of the individual technologies as much as possible.
