• Verification of the Analytical Traffic Model of a Multidomain IMS/NGN Using the Simulation Model

  Publikacja

  • S. Kaczmarek
  • M. Sac

  - Advances in Intelligent Systems and Computing - Rok 2016

  In this paper we verify 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). For this reason a proper simulation model used, in which not theoretical queuing system models but the operation of real network elements and standardized call scenarios are accurately implemented. Consequently,...

  - Rok 2013

  Growing demands of information society concerned with sophisticated applications could be satisfied by ASON/GMPLS architecture comprehended as Automatically Switched Optical Network (ASON) with Generalized Multi-Protocol Label Switching (GMPLS). The ASON/GMPLS proposition represents the future direction of Next Generation Network (NGN) architecture. Therefore considerable work has to be done to examine this solution. In this aspect...

• Analytical Steady-State Model of the Pipeline Flow Process

  Publikacja

  • Z. Kowalczuk
  • M. S. Tatara

  - Rok 2018

  The paper addresses the issue of modeling the flow process in transmission pipelines. A base model used for numerical simulation is introduced. Under certain assumptions concerning steady state analysis, the differential equations describing the process are solved analytically for two cases: zero and nonzero inclination angle α. These equations describe a constant flow rate and a corresponding distribution of the pressure along...

• Simulation model for evaluation of QOS dynamic routing

  Publikacja

  • M. Czarkowski
  • S. Kaczmarek

  - Rok 2009

  Current informational networks use a large variety of technologies to support data exchange. Most of them are focused on IP protocol and include mechanisms which by definition should supply demanded QoS. One of those mechanisms is efficient path calculation - routing. Traffic offered to the network can change very rapidly in short term. Routing should support such traffic changes and all the time calculate valid paths in terms...

• Simulation model of IMS/NGN call processing performance

  Publikacja

  • S. Kaczmarek
  • M. Kaszuba
  • M. Sac

  - Zeszyty Naukowe Wydziału ETI Politechniki Gdańskiej. Technologie Informacyjne - Rok 2012

  In current telecommunications it is assumed that demands of the information society for quickly delivered services will be satisfied by the Next Generation Network (NGN) architecture, which includes IP Multimedia Subsystem (IMS) elements. To guarantee Quality of Service (QoS), proper design and dimensioning of NGN is absolutely necessary, for which appropriate models have to be proposed. As the NGN architecture is very complicated,...

• Three-dimensional conceptual model for service-oriented simulation

  Publikacja

  • W. Wang
  • W. Wang
  • J. Zander

  - Journal of Zhejiang University-SCIENCE A - Rok 2009

  n this letter, we propose a novel three-dimensional conceptual model for an emerging service-oriented simulation paradigm. The model can be used as a guideline or an analytic means to find the potential and possible future directions of the current simulation frameworks. In particular, the model inspects the crossover between the disciplines of modeling and simulation, service-orientation, and software/systems engineering. Finally,...

• Simulation model of IPMSM drive with rotor position estimator

  Publikacja

  • L. Jarzębowicz
  • K. Karwowski
  • M. Mizan

  - Computer Applications in Electrical Engineering - Rok 2009

  The paper presents a simulation model of electric drive consisting of: IPMSM motor, inverter and digital controller. The model was designed in Mathlab/Simulink. By modelling of the controller its discrete operation was taken into account in order to simulate precisely a specific sensorless control algorithm. A method for estimation of angular rotor position was proposed. Its mathematical algorithm was explained and errors were...

• Model and laboratory simulation of a induction motor for diagnostic purposes

  Publikacja

  • L. Swędrowski
  • J. Rusek

  - Metrology and Measurement Systems - Rok 2009

  Statistics say that bearings are this part of induction motors which is most susceptible to damage. The equipment employed for bearing diagnostics usually makes use of vibrations as the criterion for technical condition of the bearings. A faulty bearing results in additional motor vibrations. They are reflected in the harmonic content of stator currents. In certain operating conditions the current signal is the sole source of information...
