Opis:: G-queueing network with positive messages and signals at transient behavior is considered. A system of difference-differential equations for the state probabilities of the network is obtained. To find them and the average characteristics of the network a technique was applied based on the use of apparatus of multivariate generating functions. An expression for the generating function was obtained. An example is calculated.

Opis:: Heat pumps are an ideal solution for use in newly built passive and energy-plus buildings. One of the many problems present in such construction is the choice of the operational parameters of the lower heat source and the selection of a ground regeneration system which would enable effective regeneration in a short period of time and at a minimal cost. This article presents the heat analysis of the ground from which heat is obtained for heating purposes. The author also analyses ground heating, as the heat is delivered to it via regeneration systems. The presented in article results allow us to estimate the ground's thermal states based on lowered ambient temperature and the possible use of a lower heat pump source regeneration process. The original contribution in article is the calculation results of the ground behavior at the transient regeneration and heat consumption realized by the heat pump system.

Opis:: The object of this research is an open queueing G-network with signals with random delay. The purpose of the research is investigation of such a network at the transient behavior. It is considered the case when the intensity of the incoming flow of positive and negative messages and service intensity of messages do not depend on time. All the systems in the network are one-line. It is described the model of computer system DDoS-attacks, the effect of penetration of the virus in a computer network in the form of G-network with random delay of signals. Approximate expressions are obtained for the time-dependent probabilities of states and the average characteristics of the network. Examples are calculated.

Tytuł:: Analytical synthesis of parameter-varying filter of constant component with application to switching systems
Autorzy:: Piskorowski, J.
Kaszyński, R.
Powiązania:: https://bibliotekanauki.pl/articles/221736.pdf
Data publikacji:: 2011
Wydawca:: Polska Akademia Nauk. Czytelnia Czasopism PAN
Tematy:: data acquisition

linear time-varying systems (LTV)
Opis:: In this paper, we propose a concept of a continuous-time filter of constant component that exhibits a very short response in the time domain if compared to the traditional time-invariant filter. The improvement of the filter dynamics was achieved as a result of the time-varying parameters which were introduced to the filter structure. Such a designed filter is then applied in a system which switches many distorted signals which should be filtered as fast as possible. The paper is of review nature and presents both a theoretical background of the proposed filter and the results of simulations.

Opis:: This paper contains an investigation of an open queueing network with positive and negative messages that can be used to model the behavior of viruses in information and telecommunication systems and networks. The purpose of research is investigation of such a network at the transient behavior. We consider the case when the intensity of the incoming flow of positive and negative messages and service intensity of messages do not depend on time. It is assumed that all queueing systems of network are one-line. We obtained a system difference-differential equations for the state probabilities of the network. To find the state probabilities of the network in the transitional behavior applied a methodology based on the use of the apparatus of multidimensional generating functions. We obtained an expression for generating function. An example is calculated.
