  Publication

  • S. Gajewski

  - Archives of Transport System Telematics - Year 2019

  In the paper, 5G communication technologies implemented for Intelligent Transport Systems are discussed. Firstly, the essence of the 5G system concept is presented, and the problem of network functions virtualization (NFV) is analyzed. Moreover, the principle of virtualization is explained. Secondly, the analysis of network slicing is performed, from the point of view of transport systems implementation in the...

  The transition network for RR -increments is pre- sented in a directed and weighted graph, with vertices represent- ing RR -increments and edges corresponding to the order in a sequence of increments. The adjacency matrix and the transition matrix of this network provide a graphical tool which could be useful in the assessment of cardiac regulation. As an example, the method is applied in detecting differences between diurnal activity...

  We argue that network methods are successful in detecting nonlinear properties in the dynamics of autonomic nocturnal regulation in short-term variability. Two modes of visualization of networks constructed from RR-increments are proposed. The first is based on the handling of a state space. The state space of RR-increments can be modified by a bin size used to code a signal and by the role of a given vertex as the representation...

  - SENSORS - Year 2017

  The technique of the orthogonal projection of ionosphere electronic content variations for mapping total electron content (TEC) allows us to visualize ionospheric irregularities. For the reconstruction of global ionospheric characteristics, numerous global navigation satellite system (GNSS) receivers located in different regions of the Earth are used as sensors. We used dense GNSS networks in central Europe to detect and investigate...

  - Zeszyty Naukowe Wydziału ETI Politechniki Gdańskiej. Technologie Informacyjne - Year 2010

  Ontologie bardzo często są reprezentowane w postaci grafu, którego wierzchołkami są obiekty występujące w prezentowanej ontologii a krawędziami relacje i powiązania pomiędzy tymi obiektami. Grafy reprezentujące ontologie mogą być złożone już dla średniego rozmiaru ontologii. Stąd niezbędna jest pełna i czytelna reprezentacja elementów takiego grafu. Dostępne rozwiązania zazwyczaj nie oferują reprezentacji pełnego zbioru elementów...
