Odwzorowania międzyontologiczne w algebrze konglomeratów
PublicationModularyzacja i integracja ontologii to dziedziny, które w ostatnim okresie są obiektem intensywnego rozwoju. Rozwój nowych idei spowodował konieczność wprowadzenia ich systematyzacji i klasyfikacji. W niniejszym artykule przeanalizowano możliwość wyrażenia odwzorowań i złączeń za pomocą algebry konglomeratów oraz przedyskutowano możliwość wykorzystania roli algebry jako ujednoliconego medium opisu metod integracji i modularyzacji.

O semantyce kontekstowych baz wiedzy
PublicationW artykule omawiany jest problem poprawnego projektowania kontekstowych baz wiedzy. Rozszerzamy w nim definicje pojęć wprowadzonych przez metodę OntoClean - jedną z najbardziej znanych metod oceny jakości ontologii niekontekstowych. Pozwala nam to na sformułowanie wymagań jakościowych dla porjektów uwzględniających semantykę kontekstów. Następnie analizujemy pod kątem tych wymagań metodę projektowania kontekstowych baz wiedzy SIM.

Scheduling on Uniform and Unrelated Machines with Bipartite Incompatibility Graphs
PublicationThe problem of scheduling jobs on parallel machines under an incompatibility relation is considered in this paper. In this model, a binary relation between jobs is given and no two jobs that are in the relation can be scheduled on the same machine. We consider job scheduling under the incompatibility relation modeled by a bipartite graph, under the makespan optimality criterion, on uniform and unrelated machines. Unrelated machines...

Modelling and Simulation of a New Variable Stiffness Holder for Milling of Flexible Details
PublicationModern industry expectations in terms of milling operations often demand the milling of the flexible details by using slender ball-end tools. This is a difficult task because of possible vibration occurrence. Due to existence of certain conditions (small depths of cutting, regeneration phenomena), cutting process may become unstable and self-excited chatter vibration may appear. Frequency of the chatter vibration is close to dominant...

Rapid multi-objective design optimization of miniaturized impedance transformer by Pareto front exploration
PublicationFast multi-objective optimization of compact impedance transformer is discussed. A set of alternative designs representing possible trade-offs between conflicting design criteria, i.e., electrical performance (here, wideband matching) and the structure size, is obtained through Pareto front exploration by means of surrogate-assisted methods.

Rapid multi-objective optimization of antennas using nested kriging surrogates and single-fidelity EM simulation models
PublicationEver increasing performance requirements make the design of contemporary antenna systems a complex and multi-stage process. One of the challenges, pertinent to the emerging application areas but also some of the recent trends (miniaturization, demands for multi-functionality, etc.), is the necessity of handling several performance figures such as impedance matching, gain, or axial ratio, often over multiple frequency bands. The...

Robust unsupervised georeferencing algorithm for aerial and satellite imagery
PublicationIn order to eliminate a human factor and fully automate the process of embedding the spatial localization information in a remote sensed image the integrated georeferencing method was proposed. The paper presents this unsupervised and robust approach which is comprised of pattern recognition, using SIFT-based detector, and RANSAC based outlier removal with matching algorithm.

Metoda wyznaczania kontekstu dla aplikacji sterowania zdarzeniami
PublicationPrzedstawiono metodę rozszerzenia aplikacji poprzez wprowadzenie elementów kontekstu środowiska działania. Definicja kontekstu jest oparta na ogólnej ontologii kontekstu. dane poczodzace ze środowiska są przetwarzane przez okreslone warunki. Jako algorytm przetwarzania została wykorzystana śieć Petriego, dzieki czemu aplikacja może we właściwy sposób reagować na zdarzenia zachodzące w otoczeniu. W taki sposób są zbudowane aplikacje...

Adaptive Method for Modeling of Temporal Dependencies between Fields of Vision in Multi-Camera Surveillance Systems
PublicationA method of modeling the time of object transition between given pairs of cameras based on the Gaussian Mixture Model (GMM) is proposed in this article. Temporal dependencies modeling is a part of object re-identification based on the multi-camera experimental framework. The previously utilized Expectation-Maximization (EM) approach, requiring setting the number of mixtures arbitrarily as an input parameter, was extended with the...
