Identification and validation of material parameters for isotropic damage model in viscoplastic flow conditions
PublicationW pracy przedstawiono trzy różne sposóby identyfikacji parametrów materiałowych dla izotropowego modelu zniszczenia w warunkach płynięcia lepkoplastycznego. W celu ustalenia który sposób daje najlepsze rezultaty przeprowadzono każdą z identyfikacji dla wybranego materiału, a następnie dokonano ich oceny porównując wyniki symulacji numerycznych z wynikami eksperymentów. W pracy pokazano również praktyczne zastosowanie modelu - przykład...

Ważone umieszczanie grafów jako model optymalizacji komunikacji w sieciach heterogenicznych
PublicationUmieszczenie grafu w grafie jest odwzorowaniem pomiędzy parą grafów. Graf umieszczany reprezentuje sieć komunikujących się ze sobą zadań, natomiast graf docelowy dostępną architekturę wykonania tych zadań. Problem polega na takim odwzorowaniu wierzchołków i krawędzi, aby zminimalizować koszty wynikające z potrzeby użycia zastępczych ścieżek w grafie docelowym. W klasycznym modelu przyjmuje się, że oba grafy są proste i ich krawędzie...

Noise spectral density computation based on finite element model of piezoceramic sensor
PublicationThe high sensitivity with wide bandwidth is required for sensor applications in non-destructive testing (NDT). The sensitivity of piezoceramic sensors demands to minimize their noise especially thermal noise, polarisation noise and low frequency 1/f noise,which are the main sources of voltage or current fluctuation in this sort of sensors. For simplicity, only the piezoceramic part of sensor was under study. the theoretical and...

Study of Soil Temperature and Moisture Changes in a Physical Model of an Underground Cable Line
PublicationThe ampacity of power cables is highly dependent on the thermal resistivity of the soil in which they are laid. The lower it is, the higher this ampacity. The thermal resistivity of the soil decreases as its moisture increases. Therefore, it is preferable that the soil around the cables has high moisture. Unfortunately, the heat generated in heavily loaded cables causes the migration of moisture from the surrounding soil, which...

Evaluation Of Single Pole Auto-Reclosing Effectiveness With Nonlinear Secondary Arc Model
PublicationThe paper discusses two evaluation methods of single pole auto-reclosing process effectiveness in HV transmission lines. Secondary arc current and recovery voltage results obtained by load flow calculation are compared to the results obtained by the time domain simulations. Moreover, a non-linear secondary arc implementation is presented. The authors indicate, that precise representation of secondary electric arc leads to more...

Wild oscillations in a nonlinear neuron model with resets: (II) Mixed-mode oscillations
PublicationThis work continues the analysis of complex dynamics in a class of bidimensional nonlinear hybrid dynamical systems with resets modeling neuronal voltage dynamics with adaptation and spike emission. We show that these models can generically display a form of mixed-mode oscillations (MMOs), which are trajectories featuring an alternation of small oscillations with spikes or bursts (multiple consecutive spikes). The mechanism by...

Expectation-Maximization Model for Substitution of Missing Values Characterizing Greenness of Organic Solvents
PublicationOrganic solvents are ubiquitous in chemical laboratories and the Green Chemistry trend forces their detailed assessments in terms of greenness. Unfortunately, some of them are not fully characterized, especially in terms of toxicological endpoints that are time consuming and expensive to be determined. Missing values in the datasets are serious obstacles, as they prevent the full greenness characterization of chemicals. A featured...
