Detection of ERP components-comparison of basic methods and their modifications

ŘONDÍK, T., CINIBURK, J. Detection of ERP components-comparison of basic methods and their modifications. 2011.
Abstract PDF BibTeX

The presentation deals with event-related potential (ERP) components detection using wavelet transform (both continuous and discrete form), matching pursuit algorithm and Hilbert- Huang transform. The EEG/ERP domain is shortly introduced and essential information about EEG and ERP signals is given. The wavelet transform, matching pursuit algorithm and Hilbert- Huang transform are introduced and their suitability for ERP components detection is described. Experimental results obtained by using these algorithms for P3 components detection are summarized.

A new cognitive component of visualization tool for diagnosis and monitoring Alzheimer´s disease and other dementias: COGVIT

PAPEŽ, V., JAROŠ, P., ARAUJO, C., PINO, M., BÁEZ, P. A new cognitive component of visualization tool for diagnosis and monitoring Alzheimer´s disease and other dementias: COGVIT. 2011.
Abstract PDF BibTeX

We propose a new computational tool to visualize medical records and to extract information from, COGVIT. Speci?cally it deals with medical records based on dementia diagnosis. These records are processed by the Sanger?s arti?cial neural network and the result in the form of principal components is visualized. The main aim of COGVIT is to aid and to facilitate the diagnosis, prognosis and monitoring of dementia as well as patients follow-up. The work deals with data storing, it describes how to use COGVIT with current EDEVITALZH database also like a standalone application and it implements software solution like a web-based application.

Transformation of object-oriented code into semantic web using Java annotations

JEŽEK, P., MOUČEK, R. Transformation of object-oriented code into semantic web using Java annotations. In ICEIS 2011. Lisabon: SciTePress, 2011. s. 1-4. ISBN: 978-989-8425-53-9
Abstract PDF BibTeX

This paper deals with difficulties occurring during transformation of schema and data from an object-oriented code to a semantic web representation (RDF, OWL). The authors describe differences in semantic expressivity between the object-oriented approach and the semantic web approach and look for the ways to fill this semantic gap. Then some existing approaches with their difficulties are introduced and a preliminary idea using Java annotations is proposed. Java annotations add missing semantic information into Java code, which is consequently processed by the proposed framework and serialized into output semantic web structure (OWL).

Influence of mental load on driver´s attention

MOUČEK, R., ŘONDÍK, T. Influence of mental load on driver´s attention. In Electromobility Congress proceedings. Praha: CTU Praha, FTS, 2011. s. 1-3. ISBN: 978-80-01-04818-4
Abstract PDF BibTeX

This preliminary paper deals with influence of mental load on driver?s attention. EEG (electroencephalography) and ERP (Event related potentials) techniques are used for investigation of the level of driver?s attention. A short overview of experiments dealing with drivers? attention is given and the ERP technique and the P3 component are described. General assumptions related to P3 amplitude and P3 latency are introduced. Then experimental design is described. At present the resulting EEG/ERP data are analyzed and their interpretation will be provided during congress presentation and in the final version of the paper.

Integration of signal processing methods into EEG/ERP system

JEŽEK, P., MOUČEK, R. Integration of signal processing methods into EEG/ERP system. In BIOSTEC 2011. Setúbal: SciTePress, 2011. s. 563-566. ISBN: 978-989-8425-34-8
Abstract PDF BibTeX

This paper deals with the processing of signals from EEG/ERP experiments. Selected methods for EEG/ERP signal processing are shortly presented. Since these methods are usually implemented for various platforms and within various tools, a new designed and developed software system, which allows users running them uniformly, is presented. The methods are added and processed as plug-ins. It ensures a high modularity and flexibility of the system. The main system components (JERPA, JUIGLE) are introduced and shortly described.
