  - EUROPEAN JOURNAL OF ORGANIC CHEMISTRY - Year 2019

  A very mild method for the introduction of functionalized alkylselenyl group at C-3 position of the indole ring was developed. The proposed procedure consists of an electrophilic substitution of indole and its derivatives with bis(O,O-diisopropoxyphosphorothioyl) diselenide and subsequent cleavage of the P–Se bond with tetrabutylammonium fluoride in the presence of various electrophilic reagents. This method can be successfully...

  - NATURE - Year 2019

  “The struggle for light” is how the Swiss architect Le Corbusier described the history of architecture in 1935. Today, with the skies crowded out by buildings in modern cities, those words should ring in the ears of policymakers and planners. Skyscraper construction is booming. China is the leader, last year completing 88 of the 143 buildings around the world that are taller than 200 metres (see ‘Vertical growth’). As the nation’s...

  - COMPOSITES PART B-ENGINEERING - Year 2016

  This work highlights the importance of nanoclay dispersion state in the nanocomposites containing polyamide 6 (PA6), nanoclay and elastomers as well as clay localization at the interface of thermoplastic/elastomer. Morphology and mechanical properties of a series of nanocomposites containing acrylonitrile butadiene rubber (NBR), glycidyl methacrylate-grafted NBR (NBR-g-GMA), and combined NBR/NBR-g-GMA were compared and discussed...

  - Journal of KONES - Year 2008

  Każdego dnia w systemie transportowym na świecie ginie ponad 3 tys. osób, z czego większość w wypadkach drogowych. W Polsce, podobnie jak w innych krajach UE, obserwuje się podobne dysproporcje pomiędzy skalą wypadków drogowych i wypadków w innych rodzajach transportu. Z punktu widzenia zarządzania bezpieczeństwem, każdy z systemów gałęziowych jest zorganizowany w inny sposób. Dotyczy to baz danych, instytucji zarządzających infrastrukturą...

• Using MusicXML to evaluate accuracy of OMR Systems

  Publication

  • M. Szwoch

  - Year 2008

  In this paper a methodology for automatic accuracy evaluation in optical music recognition (OMR) applications is proposed. Presented approach assumes using ground truth images together with digital music scores describing their content. The automatic evaluation algorithm measures differences between the tested score and the reference one, both stored in MusicXML format. Some preliminary test results of this approach are presented...
