Opis:: A partition, i.e. a division of a finite set into nonempty subsets, is a simple and essential concept of quantitatively understanding the reality. A partition of a number n is a decreasing sequence of natural numbers whose sum equals n. Greater numbers are seen only in terms of the union of partitions. The most important processes such as stochastic processes of branching processes can be expressed most simply using the language of partitions. By means of partitions any Sacała’s line defines a wide class of related quasibranching processes which are more general than Markov processes. Didactically such an approach is extremely useful.

Opis:: W pracy są badane dwa modele procesów gałązkowych, pierwszy bazujący na procesie Galtona-Watsona, drugi na złożonym procesie Poissona. Badana jest najwyższa cząstka w modelu poprzez określenie jej asymptotyki prawie na pewno z dokładnością do stałej.
The purpose of this study is to investigate two related spatial branchingmodels with the unbounded branching intensity. The objective is to describe theasymptotic behaviour of the extremal particle.

Opis:: The aim of this study is to analyse the effect of reducing the number of secondary damage to profit from the work of a technical object. Considering the criterion function that describes the average profit from the work of a technical object in the operation system. The study analyses a model of profit optimization, in which the design criterion function is based on the properties of Poisson branch process. Criterion function that describes the average gain is considered in the work at sufficiently general factors. Profit lifting model from the work of a technical facility is numerically exemplified. For the analysed electrical subsystem, intervals of time between the initial damage have exponential distribution, and between secondary damage - gamma distribution. In the presented example, the ability of profit optimization in operation systems of technical objects is demonstrated.

Tytuł:: An Application of General Branching Processes to a Cell Cycle model With Two Uncoupled Subcycles and Unequal Cell Division

mother-daughter correlation
Opis:: A cell population model is constructed and analysed in the frameworkof general branching process theory. The model uses the idea that the DNA division cycle and the cell growth cycle are loosely coupled. The cell division is assumed to be unequal and the structure variables of the modelare size and growth, where the growth is regulated by supramitotic growth control. An explicit expression for the stable birth type distributionis given and asymptotics, such as the alpha- and beta_1-curve and various size distributions, are derived. We also prove that the microheterogeneity ingrowth causes the mother-daughter life length correlation to be non-negative.
