  • Call Processing Performance in a Multidomain IMS/NGN with Asymmetric Traffic
    Publication

    - Year 2014

    In this paper we continue our research using the previously proposed analytical traffic model of a multidomain Next Generation Network (NGN), which is standardized for delivering multimedia services based on the IP Multimedia Subsystem (IMS). The aim of the model is to assess mean Call Set-up Delay (CSD) and mean Call Disengagement Delay (CDD), which are standardized call processing performance parameters. The output variables...

  • Całkowanie nieliniowych równań dynamiki ciała sztywnego i powłok sprężystych.
    Publication

    - Year 2004

    Ogólnym celem pracy jest studium i opracowanie algorytmów numerycznych do analizy dynamicznej układów mechanicznych. Opracowane i analizowane schematy całkowania nieliniowych równań ruchu odnoszą się do konstrukcji sformułowanych w ramach teorii sześcioparametrowej (modele bryły sztywnej, przestrzennych konstrukcji prętowych oraz niektóre teorie płyt i powłok). Podstawę pracy stanowią rozważania teoretyczne z zakresu metod numerycznych...

  • Camera angle invariant shape recognition in surveillance systems
    Publication

    A method for human action recognition in surveillance systems is described. Problems within this task are discussed and a solution based on 3D object models is proposed. The idea is shown and some of its limitations are talked over. Shape description methods are introduced along with their main features. Utilized parameterization algorithm is presented. Classification problem, restricted to bi-nary cases is discussed. Support vector...

  • Camera Orientation-Independent Parking Events Detection
    Publication

    The paper describes the method for detecting precise position and time of vehicles parking in a parking lot. This task is trivial in case of favorable camera orientation but gets much more complex when an angle between the camera viewing axis and the ground is small. The method utilizes background subtraction and object tracking algorithms for detecting moving objects in a video stream. Objects are classified into vehicles and...

  • Camera sabotage detection for surveillance systems
    Publication

    Camera dysfunction detection algorithms and their utilization in realtime video surveillance systems are described. The purpose of using the proposed analysis is explained. Regarding image tampering three algorithms for focus loss, scene obstruction and camera displacement detection are implemented and presented. Features of each module are described and certain scenarios for best performance are depicted. Implemented solutions...

  • Can augmented democracy fulfil the ideal of deliberative democracy?
    Publication

    - Year 2023

    New technologies can broaden the scope of human limits. We can fly to the moon thanks to rocket science, we can communicate with each other by mobile phones and WiFi and we can exceed human life with medical equipment like pacemakers. But there are aspects of our life that still are very distrustful of implementing new technology into functioning. An example of such a field of our everyday life is...
