• The database of odd algebraic periods for quasi-unipotent self-maps of a space having the same homology group as the connected sum of g tori

  Dane Badawcze

  open access

  • G. Graff
  • A. Myszkowski

  The dataset consists of 20 files indexed by numbers g=1,...,20. Each file provides sets of odd algebraic periods for all quasi-unipotent self-maps of a space having the same homology groups as the connected sum of g tori. Let us remark that each data set covers all algebraical restrictions that come from zeta functions for the sets of  minimal  Lefschetz...

• Convergence of rational multistep methods of of Adams-Padé type

  Publikacja

  • M. M. Łapińska
  • W. Auzinger

  - BIT NUMERICAL MATHEMATICS - Rok 2012

  Rational generalizations of multistep schemes, where the linear stiff part of a given problem is treated by an A-stable rational approximation, have been proposed by several authors, but a reasonable convergence analysis for stiff problems has not been provided so far. In this paper we directly relate this approach to exponential multistep methods, a subclass of the increasingly popular class of exponential integrators. This natural,...

• Sociology of Space

  Kursy Online

  • M. Dymnicka

  The course is aimed at discussing the significance of the city as a topic of sociological analysis. During the seminar students will discuss the relation between sociology, architecture and space. Moreover, the debate will touch on the field of culture and its role in (re)creating and (re)constructing space. Discussions will also be related to the aspect of interactions in time and space. Contemporary dilemmas and challenges in...

• Zero-Pole Space Mapping for CAD of Filters

  Publikacja

  • N. Leszczynska
  • Ł. Szydłowski
  • M. Mrozowski

  - IEEE MICROWAVE AND WIRELESS COMPONENTS LETTERS - Rok 2014

  In this paper, we propose a new space-mapping technique tailored to the CAD of microwave filters. The goal of space mapping is to achieve a satisfactory design with the minimal number of fine model evaluations. In our approach, the filter is represented by a rational function. To quickly align the coarse and fine models, and to speed up the direct optimization of the coarse model, we propose matching the zeros and poles of a rational...

  • A. Andreev

  - PROCEEDINGS OF THE INSTITUTION OF MECHANICAL ENGINEERS PART A-JOURNAL OF POWER AND ENERGY - Rok 2022

  Cooling degree-hours (CDH) received the broadest application in evaluation of the ambient air cooling efficiency in power engineering (engine intake air cooling systems) and air conditioning. The current CDH numbers are defined as a drop in air temperature multiplied by associated time duration of performance and their summarized annual number is used to estimate the annual effect achieved due to sucked air cooling in power plants...

• CONSTRUCTION TECHNOLOGY OF TIMBER-FRAME HOUSES RESISTANT TO DYNAMIC LOADS – STUDY ON MODELS OF EXTERIOR WALLS

  Publikacja

  • M. Szczepański
  • W. Migda
  • R. Jankowski

  - Advances in Science and Technology Research Journal - Rok 2015

  The aim of this paper is to show the numeric representation of experimental studies concerning the behaviour of exterior wall models of a timber-frame house under harmonic loading. A single wall model according to traditional technology of timberframe house walls (filling with mineral wool) was tested. The analysis was conducted for the following frequencies: 0.5 Hz, 1.0 Hz, 2.0 Hz and 5.0 Hz for various values of the specified...

• Modelling of wastewater treatment plant for monitoring and control purposes by state - space wavelet networks

  Publikacja

  • A. Borowa
  • M. Brdyś
  • K. Mazur

  - International Journal of Computers Communications & Control - Rok 2007

  Most of industrial processes are nonlinear, not stationary, and dynamical with at least few different time scales in their internal dynamics and hardly measured states. A biological wastewater treatment plant falls into this category. The paper considers modelling such processes for monitorning and control purposes by using State - Space Wavelet Neural Networks (SSWN). The modelling method is illustrated based on bioreactors of...
