• Design of a Multidomain IMS/NGN Service Stratum

  Publikacja

  • S. Kaczmarek
  • M. Sac

  - Rok 2018

  The paper continues our research concerning the Next Generation Network (NGN), which is standardized for delivering multimedia services with strict quality and includes elements of the IP Multimedia Subsystem (IMS). A design algorithm for a multidomain IMS/NGN service stratum is proposed, which calculates the necessary CSCF servers CPU message processing times and link bandwidths with respect to the given maximum values of mean...

• Performance Models of a Multidomain IMS/NGN Service Stratum

  Publikacja

  • S. Kaczmarek
  • M. Sac

  - Rok 2021

  This paper quantifies call processing performance (CPP) of a multidomain IMS/NGN architecture, which was proposed to deliver current and future telecommunication services with strict quality requirements, independently of the transport network technologies. A realistic simulation model is used as a reference for evaluation of the analytical results, in which vari-ous types of queuing systems are applied to model the opera-tion...

• Performance Evaluation of a Multidomain IMS/NGN Network Including Service and Transport Stratum

  Publikacja

  • S. Kaczmarek
  • M. Sac

  - Applied Sciences-Basel - Rok 2022

  The Next Generation Network (NGN) architecture was proposed for delivering various multimedia services with guaranteed quality. For this reason, the elements of the IP Multimedia Subsystem (IMS) concept (an important part of 4G/5G/6G mobile networks) are used in its service stratum. This paper presents comprehensive research on how the parameters of an IMS/NGN network and traffic sources influence mean Call Set-up Delay (E(CSD))...

• Analytical Traffic Model for a Multidomain IMS/NGN Network Including Service and Transport Stratum

  Publikacja

  • S. Kaczmarek
  • M. Sac
  • M. Cieśliński

  - Rok 2022

  This paper addresses the problem of modelling call processing performance (CPP) in a multidomain Next Generation Network (NGN) architecture including the elements of the IP Multimedia Subsystem (IMS) in service stratum and based on the Multiprotocol Label Switching (MPLS) technology in transport stratum. An analytical traffic model for such an architecture is proposed by integrating the formerly implemented submodels of service...

• Universal and contextualized public services: Digital public service innovation framework

  Publikacja

  • J. Bertot
  • E. Estevez
  • T. Janowski

  - GOVERNMENT INFORMATION QUARTERLY - Rok 2016

  In view of the rising social and economic inequalities, public service delivery should be both universal, i.e. independent of the recipients' social or economic status, and contextualized, i.e. able to compensate for different local needs and conditions. Reconciling both properties requires various forms of innovations, chief among them innovations in digital public services. Building upon the four-stage model underpinning the...

• Commitment Ladder in the Relationship between Service Providers and Customers as Added Value in Sustainable Services Development

  Publikacja

  • S. Ostrowski

  - Sustainability - Rok 2021

  The socioeconomic sphere and the relationships in which commitment occurs are important elements in the development of sustainable services. The study reported in this article identifies the elements that influence the development of the relationship between service providers and their customers and proposes a model that describes the state of the relationship between service providers and customers in terms of symmetrical commitment...

• Service and service decomposition model - theoretical foundation of it service management

  Publikacja

  • J. Pastuszak
  • M. Stolarek
  • C. Orłowski

  - FOUNDATIONS OF CONTROL AND MANAGEMENT SCIENCES - Rok 2009

  The publication contains different definitions of Service - one of the fundamental IT Service Management term. It describes types of Service attributes nad introduces so-called ''distinguish functions'' in order to propose different categories of Services. It proposes both general model of Service decomposition and practical model based on CMDB implementation limitations. In summarizes obtained results and gives some remarks about...

• A concept of pusher - barge coupling device of two-segment ship for inland waterways and coastal service

  Publikacja

  • C. Dymarski
  • R. Rolbiecki

  - Polish Maritime Research - Rok 2006

  W artykule przedstawiono założenia projektowe i koncepcję rozwiązania konstrukcyjnego oraz napędu i sterowania urządzenia sprzęgającego pchacz i barkę dwusegmentowego statku śródlądowego i przybrzeżnego. Zaprezentowane urządzenie umożliwia zarówno sztywne połączenie, jak i wzajemne kontrolowane wychylanie obu segmentów względem siebie, co w znacznym stopni zwiększa manewrowość, a tym samym bezpieczeństwo żeglugi, zwłaszcza na wąskich...
