  Publication

  - Year 2005

  Zestarzenie się populacji mierzy sie zwykle frakcją osób starszych. Miara ta nie uwzględnia rozkładu wieku wśród osób starszych. W pracy przedstawiane są nowe miary zestarzenia się populacji, których ideę zaczerpnięto z ekonomiki ubóstwa: absolutna luka wiekowa AG, relatywna luka wiekowa RAG, syntetyczna miara HRAG=HCR. RAG oraz syntetyczna miara P2. Te nowe miary testowo analizując proces zestarzenia się w 4 krajach europejskich...

• Percentage of the working age population in selected EU countries in 2006 and 2017

  Open Research Data

  • P. Kasprzak

  The phenomenon of aging of the society, and thus changes in the structure of the share of population in pre- and post-working age, is typical for all European Union countries. The median age of the population in the European Union countries in 2001-2016 increased from 38.5 years to 43 years. This is the scale of the aging of the population (Median age...

• Wireless Network Selection: A Population Dynamics Approach

  Publication

  • J. Konorski
  • A. Siwecki

  - Year 2011

  W artykule rozpatruje się środowisko wireless multihoming, gdzie terminal bezprzewodowy może w każdej chwili połączyć się z jedną z wielu dostępnych sieci bezprzewodowych. Zwrócono uwagę na rolę informacji zwrotnej z sieci powiadamiającej terminal o bieżącym stanie sieci. Zaproponowano trzy dynamiczne modele wyboru sieci, różniące się dostępem terminala do informacji zwrotnej dotyczących sieci, z którą nie jest aktualnie połączony.

  - Year 2020

  This paper presents a method based on a population in which the parameters of individuals can be processed by operators from various population-based algorithms. The mechanism of selecting operators is based on the introduction of an additional binary parameters vector located in each individual, on the basis of which it is decided which operators are to be used to modify individuals’ parameters. Thus, in the proposed approach,...

  Rozważamy strukturalny model populacyjny z dyfuzją wraz z dołączonymi warunkami brzegowymi Wentzella. Badamy przypadek o stałych współczynnikach. Dowodzimy nieujemności rozwiązań oraz badamy ich asymptotyczne zachowanie poprzez zasadę maksimum. Symulacje numeryczne potwierdzają nasze teoretyczne rozważania.

• Impact of Initial Population on Evolutionary Path Planning Algorithm

  Publication

  • Ł. Kuczkowski

  - Year 2014

  In this paper an impact of initial population on evolutionary path planning algorithm is presented. Tested algorithm is used to determine close to optimal ship paths in collision avoidance situation. For this purpose a path planning problem is defined. A specific structure of the individual path and fitness function is presented. For the simulation purposes a close to real tested environment is created. Four tests are performed....

  - JOURNAL OF COMPUTATIONAL AND APPLIED MATHEMATICS - Year 2015

  A new algorithm is proposed for the numerical solution of threshold problems in epidemics and population dynamics. These problems are modeled by the delay-differential equations, where the delay function is unknown and has to be determined from the threshold conditions. The new algorithm is based on embedded pair of continuous Runge–Kutta method of order p = 4 and discrete Runge–Kutta method of order q = 3 which is used for the...

• ANFIS-Based NPC Population Control in Video Games

  Publication

  • T. M. Boiński

  - Year 2021

  Modern computer games aim at providing rich, vivid worlds. The aim is to encourage the player to explore and interact with the in-game world. To describe the complex relations between in-game NPCs and their surrounding fuzzy logic is used. The paper presents ANFIS based population control in the video game. We present an approach allowing stabilizing the number of NPCs in-game by providing a certain amount of food to the environment....

  • Y. Hayashi

  - Year 2020

  Dynamic signature is a biometric attribute which is commonly used for identity verification. Artificial intelligence methods, especially population-based algorithms (PBAs), can be very useful in the dynamic signature verification process. They are able to, among others, support selection of the most characteristic descriptors of the signature or perform signature partitioning. In this paper, we focus on creating the most characteristic...

  We prove a weak maximum principle for structured population models with dynamic boundary conditions. We establish existence and positivity of solutions of these models and investigate the asymptotic behaviour of solutions. In particular, we analyse so called size profile.

  The dynamic signature is an attribute used in behavioral biometrics for verifying the identity of an individual. This attribute, apart from the shape of the signature, also contains information about the dynamics of the signing process described by the signals which tend to change over time. It is possible to process those signals in order to obtain descriptors of the signature characteristic of an individual user. One of the methods...

• Quadratic stochastic operators as a tool in modelling the dynamics of a distribution of a population trait

  Publication

  • K. Bartoszek
  • M. Pułka

  - Year 2013

  Quadratic stochastic operators can exhibit a wide variety of asymptotic behaviours and these have been introduced and studied recently. In the present work we discuss biological interpretations that can be attributed to them. We also propose a computer simulation method to illustrate the behaviour of iterates of quadratic stochastic operators.
