In the diagnosis and treatment of epilepsy, an electroencephalography (EEG) is one of the main tools. However visual inspection of EEG is very time consuming. Automatic extraction of important EEG features saves not only a lot of time for neurologist, but also enables a whole new level for EEG analysis, by using data mining methods. In this work we present and analyse methods to extract some of these features of EEG – drowsiness score and centrotemporal spikes. For spike detection, a method based on morphological filters is used. Also a database design is proposed in order to allow easy EEG analysis and provide data accessibility for data mining algorithms developed in the future.

The algorithm of automatic EEG spike detection and its implementation is described in this article. The algorithm implemented is based on mathematical morphological filters which distinguishes background brain activity from EEG spikes. The implementation of the algorithm is system independent, it can be deployed on both personal computers and clusters with MPI parallel computing support.

The article presents an application of computer vision methods to traffic flow monitoring and road traffic analysis. The application is utilizing image-processing and pattern recognition methods designed and modified to the needs and constrains of road traffic analysis. These methods combined together gives functional capabilities of the system to monitor the road, to initiate automated vehicle tracking, to measure the speed, and to recognize number plates of a car. Software developed was applied in and approved with video monitoring system, based on standard CCTV cameras connected to wide area network computers.

Mažoms ir vidutinio dydžio įmonėms aktuali problema yra pasirinkti ir įdiegti integruotą, lanksčią ir atvirą automatizuotų organizacinių procesų valdymo sistemą. Siekiant tai padaryti efektyviai, reikalingi adekvatūs moksliniai taikomieji tyrimai ir programinės įrangos produkto parinkimo etapai. Bendras skirtingų organizacinių procesų valdymas yra būtina prielaida šių įmonių konkurencingumui didėti. Straipsnyje pateikiama informacinių technologijų rinkos analizė ne tik atskleidžia veiksnius, nusakančius poreikį įmonėms įdiegti veiklos procesus automatizuojančias sistemas, bet ir vertina informacinių technologijų įmonių bandymus integruoti šias sistemas. Kadangi analizė remiasi atlikto projekto darbais, ji pateikia sistemų lanksčios integracijos ir plėtros sprendimų rekomendacijas. Šis darbas parengtas pagal projektą „Integruota, lanksti bei atvira automatizuotų organizacinių procesų valdymo sistema mažoms ir vidutinėms įmonėms: moksliniai taikomieji tyrimai ir bandomojo programinės įrangos produkto kūrimas“ (identifikacijos projekto Nr. BPD04-ERPF-3.1.7-03-05/0019), įgyvendinant Lietuvos 2004–2006 m. bendrojo programavimo dokumento 3 prioriteto „Gamybos sektoriaus plėtra“ 1 priemonės „Tiesioginė parama verslui“ veiklų grupę „Mokslinių tyrimų ir plėtros veikla (taikomieji tyrimai ir technologinė plėtra)“, skirtą pramonei ir verslui. Reikšminiai žodžiai: informacinės sistemos, organizacinių procesų valdymas, informacinių technologijų rinka, integruoti sprendimai Information technologies market analysis in the aspect of automated management of organizational processesAlgimantas Juozapavičius, Kazimieras Mickus, Gediminas Mikaliūnas, Mindaugas Pelanis, Evaldas Urbonas SummayAn urgent issue of small and medium enterprises is to select and implement an integrate, flexible and open management system for automated organizational processes. To do this effectively, adequate applied research is required along with software selection stages. United management of different organizational processes is an indispensable condition for increasing the competitiveness of enterprises. The information technologies market analysis presented in the article not only deals with the factors expressing the necessity for enterprises to implement automated systems of business processes, but also estimates efforts of IT eterprises in such systems’ integration. Since this analysis is based on the performed project work, it presents recommendations for the integration and development of a flexible system. This work is supported by the project “Integrated, flexible and open system of automated organizational process management for small and medium enterprises: applied research and the development of software demo version” (project identification number BPD04-ERPF-3.1.7-03-05/0019), in the realization of the Lithuanian 2004–2006 single programming document 3 priority “Development of productive sector” meassure 1 “Direct support of business” action group “Research and development activities (applied research and development of technologies)” for industry and business. Key words: information systems, organizational process management, IT market, integrated solutions.

We have developed the flexible scheme for computer-aided detection (CAD) of interstitial lung diseases on chest radiographs. These schemes enable us to perform diagnostics in the broad circumstances of pneumonia and other interstitial lung diseases. It is applied in the case of children pneumonia when conditions are difficult to standardize. In the adults' case the schemes of CAD are more adaptive, as there are more characteristic interstitial lung tissue's changes to all kinds of pathological conditions. Even in the norm of drawing there are more visible and more highlighted features, leading to better results. The CAD scheme works as follows. For the first of all, we are using adopted algorithms of active contours to select the area of lungs, and then to divide this area into subareas - regions of interest (40 different ROI). Then ROIs were subjected to the 2-dimensional Daubechies wavelet transform, and only main transformation was used. For every transformation 12 texture measures were calculated. Principal component analysis (PCA) was used to extract 2 main components for each ROI, and these components were compared to predictive component region.
