  - Studia Informatica Pomerania - Year 2016

  The paper presents a method of hardware load prediction using workload models based on application categories and high-level characteristics. Application of the method to the problem of optimization of virtual machine scheduling in a heterogeneous Infrastructure as a Service (IaaS) computing cloud is described.

  - TASK Quarterly - Year 2015

  Multimedia stream processing into two cooperative different systems (cluster platform and virtual lab) is considered. The considered selected information about the systems is presented and the idea of its communication when executing the distributed application is proposed. A general schema of the communication architecture is given. Tests of data transmission quality are considered and their results are presented.

  - Year 2013

  Zaprezentowano metody przetwarzania strumieni multimedialnych na platformie KASKADA. Przedstawiono koncepcję dystrybucji strumieni do zadań obliczeniowych wykonywanych na poszczególnych węzłach klastra komputerowego. Zaprezentowano w jaki sposób dane strumieni są konwertowane i dostosowywane do wykorzystywania przez algorytmy obudowane w tzw. Ramkę KASKADA. Przedstawiono projekt i implementację archiwum strumieni multimedialnych...

  - TASK Quarterly - Year 2012

  In this paper we present a genetic algorithm (GA) for creating hypothetical virtual portraits of historical figures and other individuals whose facial appearance is unknown. Our algorithm uses existing portraits of random people from specific historical period and social background to evolve a set of face images potentially resembling the person whose image is to be found. We then use portraits of the person's relatives to judge...
