  - Japanese journal of statistics and data science - Rok 2021

  We consider a random dynamical system, where the deterministic dynamics are driven by a finite-state space Markov chain. We provide a comprehensive introduction to the required mathematical apparatus and then turn to a special focus on the susceptible-infected-recovered epidemiological model with random steering. Through simulations we visualize the behaviour of the system and the effect of the high-frequency limit of the driving...

• On asymptotic periodicity of kernel double Markovian operators

  Publikacja

  • W. Bartoszek
  • M. Krzemiński

  - POSITIVITY - Rok 2021

  It is proved that a kernel, doubly Markovian operator T is asymptotically periodic if and only if its deterministic σ-field Σd(T)(equivalently Σd(T∗)) is finite. It follows that kernel doubly Markovian operator T is asymptotically periodic if and only if T∗ is asymptotically periodic.

• Objectivity in the non-Markovian spin-boson model

  - PHYSICAL REVIEW A - Rok 2017

  Objectivity constitutes one of the main features of the macroscopic classical world. An important aspect of the quantum-to-classical transition issue is to explain how such a property arises from the microscopic quantum theory. Recently, within the framework of open quantum systems, there has been proposed such a mechanism in terms of the so-called spectrum broadcast structures. These are multipartite quantum states of the system...

• Solvability of a Markovian model of an IEEE 802.11 LANunder a backoff attack

  Publikacja

  • J. Konorski

  - Rok 2005

  Przedstawiono ulepszony model jakościowy mechanizmu CSMA/CA dla bezprzewodowych sieci lokalnych z indywidualną konfiguracją okien rywalizacji. Sformułowano warunki dostateczne rozwiązywalności modelu oraz wykazano obecność bezwarunkowej motywacji do zmniejszania okien rywalizacji.

• Semi-Markovian models of the process of technical state changes of technical objects.

  Publikacja

  • J. Girtler

  - Rok 2004

  Najistotniejszym problemem eksploatacji wszystkich obiektów technicznych (urządzeń) jest problem racjonalnego (a zwłaszcza optymalnego) decyzyjnego sterowania procesem zmian stanów technicznych tych obiektów. Sterowanie takie może być realizowane w przypadku zastosowania między innymi modelu wspomnianego procesu zmian stanów. Mając to na uwadze, w opracowaniu tym przedstawiono formalny opis procesu eksploatacji obiektów technicznych...

• Threshold Attendance under Soft-Crash Model: TAG Protocol and Markovian Analysis

  Publikacja

  • J. Konorski

  - Rok 2018

  A realistic and systematic network evaluation should subsume an availability model and a failure model. We combine a "hard availability" model we call threshold attendance, whereby a certain minimum number of network elements must be present at any time, with a soft-crash failure model, whereby after experiencing a failure, a network element is still able to function correctly for a while in an emergency mode at a risk of a major...

• Assesment of operation of ship main diesel engine using the theory of semi-markovian and markov processes.

  Publikacja

  • J. Rudnicki

  - Journal of KONES - Rok 2009

  To precisely determine the task it is necessary to specify also its duration time, apart from conditions in which it will be realized. When considering propulsion engine, i.e. the main element of ship propulsion system, especially important becomes not only the problem which amount of energy could be at one's disposal but also within which time interval it could be delivered. Therefore apart from applying the commonly used reliability...

• Central heating temperature control algorithm for systems with condensing boilers

  Publikacja

  • P. A. Kaczmarek

  - Rok 2016

  The problem of control of a central heating system in a small residence is considered. It is assumed that the system is based on a condensing boiler. Since the boiler efficiency depends on a returning water temperature, the proposed control goal is to provide proper air temperature in the residence as well as the lowest possible water temperature. The proposed algorithm is applied to two buildings. Both of them have the same heating...
