Local basis function method for identification of nonstationary systems
PublicationThis thesis is focused on the basis function method for the identification of nonstationary processes. The first chapter describes a group of models that can be identified using the basis function method. The next chapter describes the basic version of the basis function method, including its algebraic and statistical properties. The following section introduces the local basis function (LBF) method: its properties are described...

Healthy financial system of local government on the example of Poland
Publicationhealthy local government financial system lays the foundation for the ability of local government units (LGUs) to carry out public tasks at the current qualitative and quantitative level and to meet their obligations in the short and long term. A healthy financial system of local government is a system that is adequate, stable, unified, consistent, transparent, diversified, counter-cyclical, guarantees the financial independence...

Upscaling unsaturated flow in binary porous media with air entry pressure effects
PublicationArtykuł dotyczy przepływu w gruntach nienasyconych, zawierających soczewki (inkluzje) materiału gruboziarnistego. Materiał inkluzji charakteryzuje się niższą wartością ciśnienia wejścia powietrza niż materiał tła. Podczas infiltracji część powietrza zostaje zamknięta w inkluzjach, po całkowitym wypełnieniu wodą materiału tła. Z drugiej strony, drenaż inkluzji rozpoczyna się dopiero wtedy, gdy przekroczone zostanie ciśnienie wejścia...

Two-phase flow in heterogeneous porous media with non-wetting phase trapping
PublicationThis article presents amathematical model describing flowof two fluid phases in a heterogeneous porous medium. Zaproponowano model matematyczny przepływu dwufazowego w drobnoziarnistym ośrodku porowatym zawierającym inkluzje gruboziarniste. Inkluzje charakteryzują się niższą wartością ciśnienia wejścia dla płynu niezwilżającego (np. powietrze, ropa naftowa) niż materiał podstawowy. Podczas nawadniania takiego ośrodka dochodzi do...

Determinanty kreowania wartości marki poprzez media społecznościowe w gospodarce sieciowej
PublicationGłównym problemem badawczym podejmowanym w pracy, jest określenie struktury czynników determinujących kreowanie wartości marki w mediach społecznościowych. Dla rozwiązania tego problemu wykonano dwa badania. Pierwsze z nich dotyczyło określenia relacji pomiędzy wartością marki a jej pozycją w sieciach społecznościowych (model BV). Badanie to zrealizowano w oparciu o metody ilościowe: analizę statystyczną danych wtórnych i danych...

A variational approach of homogenization of piezoelectric composites towards piezoelectric and flexoelectric effective media
PublicationThe effective piezoelectric properties of heterogeneous materials are evaluated in the context of periodic homogenization, whereby a variational formulation is developed, articulated with the extended Hill macrohomogeneity condition. The entire set of homogenized piezoelectric moduli is obtained as the volumetric averages of the microscopic properties of the individual constituents weighted by the displacement and polarization...

Crank–Nicolson FDTD Method in Media Described by Time-Fractional Constitutive Relations
PublicationIn this contribution, we present the Crank-Nicolson finite-difference time-domain (CN-FDTD) method, implemented for simulations of wave propagation in media described by time-fractional (TF) constitutive relations. That is, the considered constitutive relations involve fractional-order (FO) derivatives based on the Grünwald-Letnikov definition, allowing for description of hereditary properties and memory effects of media and processes....

FDTD Method for Electromagnetic Simulations in Media Described by Time-Fractional Constitutive Relations
PublicationIn this paper, the finite-difference time-domain (FDTD) method is derived for electromagnetic simulations in media described by the time-fractional (TF) constitutive relations. TF Maxwell’s equations are derived based on these constitutive relations and the Grünwald–Letnikov definition of a fractional derivative. Then the FDTD algorithm, which includes memory effects and energy dissipation of the considered media, is introduced....

Noninvasive glucose sensing in scattering media using OCT, PAS, and TOF techniques.
PublicationW pracy przedstawiono możliwości wykorzystania optycznej tomografii koherencyjnej (OCT), spektroskopii fotoakustycznej (PAS)i spektroskopii czasu przelotu (TOF) w pomiarach glukozy w ośrodku silnie rozpraszającym. Równolegle opracowano modele propagacji światła w tych ośrodkach wykorzystując metodę Monte Carlo. W pomiarach wykorzystano ''Intralipid'' jako fantom tkanki. W dalszych badaniach wykorzystano mięso wieprzowe i dokonano...

Text Mining Algorithms for Extracting Brand Knowledge; The fashion Industry Case
PublicationBrand knowledge is determined by customer knowledge. The opportunity to develop brands based on customer knowledge management has never been greater. Social media as a set of leading communication platforms enable peer to peer interplays between customers and brands. A large stream of such interactions is a great source of information which, when thoroughly analyzed, can become a source of innovation and lead to competitive advantage....
