Efektywność szkół wyższych w Polsce na tle uczelni europejskich – analiza dla dziewiętnastu krajów
PublicationW artykule przeprowadzono analizę empiryczną efektywności szkół wyższych wraz z estymacją czynników ją determinujących. Próba badawcza składa się z uczelni z 19-tu krajów europejskich i obejmuje dane dla lat 2011-2014. Na podstawie nieparametrycznej metody DEA oszacowano wskaźniki efektywności gdzie za nakłady przyjęto: wartość przychodów i liczbę nauczycieli akademickich. W wynikach działalności uczelni ujęto liczbę absolwentów...

Wpływ liczby mieszkańców na obliczenia ilości ścieków w projektowaniu kanalizacji sanitarnej
PublicationZmiana sposobu rozliczania zużycia wody, promocja wodooszczędnych technologii oraz uszczelnienie kanałów wyraźnie wpłynęły na ilość odprowadzanych do kanalizacji ścieków. Obecnie stwierdzić można, że opracowania z lat 70-tych XX wieku podają zawyżone wskaźniki odpływu ścieków, skutkiem czego są problemy eksploatacyjne. Bez wątpienia, prawidłowe zaprojektowanie kanalizacji sanitarnej to zadanie trudne, wymagające między innymi prawidłowego...

Flood Classification in a Natural Wetland for Early Spring Conditions Using Various Polarimetric SAR Methods
PublicationAbstract--- One of the major limitations of remote sensing flood detection is the presence of vegetation. Our study focuses on a flood classification using Radarsat-2 Quad-Pol data in a natural floodplain during leafless, dry vegetation (early spring) state. We conducted a supervised classification of a data set composed of nine polarimetric decompositions and Shannon entropy followed by the predictors' importance estimation to...

Sprzedaż praw telewizyjnych jako kluczowe źródło przychodów wielkoformatowych imprez sportowych
PublicationDo początku lat 80. XX wieku przychody z tytułu sprzedaży praw telewizyjnych były podrzędnym, choć systematycznie zyskującym na znaczeniu źródłem wpływów organizacji sportowych. Od tego czasu obserwuje się dynamiczny wzrost wszystkich ważnych wskaźników związanych z realizacją transmisji telewizyjnych. W niniejszym opracowaniu Autor podejmuje się analizy podstawowych wielkości związanych z tym wzrostem, takich jak: liczba godzin...

Allocation of tools to machines in a flexible machining cell. W: Computerintegrated manufacturing. Advanced design and management. Ed.: B. Skołud, D. Krenczyk. Warszawa: Wydaw. Nauk.-Tech.**2003 s. 486-493, 5 rys. 2 tabl.bibliogr. 10 poz. Przydział narzędzi do obrabiarek w elastycznym gnieździe obróbkowym.
PublicationPrzedstawiono zagadnienia modelowania i analizy przepływu narzędzi w wielo-maszynowym elastycznym gnieździe, zorientowanym na wytwarzanie przedmiotów klasy korpus. Zaproponowano oryginalną metodę i algorytmy współbieżnego sze-regowania zadań produkcyjnych i przydziału narzędzi w warunkach ograniczono-ści zasobów systemu. Wybrane strategie przydziału operacji technologicznych i adekwatnych zestawów narzędziowych poddano analizie...

Comparative studies of manufacturing strategies within multi-machine production systems using simulation
PublicationZaprezentowano metodykę budowy struktur przestrzennych systemów produkcji typu gniazdowego wg zasad technologii grupowej, wykorzystując zaproponowane modele i algorytmy analizy zbiorów/relacji rozmytych. Generowane, z wykorzystaniem tych algorytmów, przebiegi procesów porównywano z przebiegami procesów w strukturach przestrzennych typu hybrydowego, tj. o wspólnych zasobach. Odnosząc się do zdefiniowanego studium przypadku, wykazano...

Iterative‐recursive estimation of parameters of regression models with resistance to outliers on practical examples
PublicationHere, identification of processes and systems in the sense of the least sum of absolute values is taken into consideration. The respective absolute value estimators are recognised as exceptionally insensitive to large measurement faults or other defects in the processed data, whereas the classical least squares procedure appears to be completely impractical for processing the data contaminated with such parasitic distortions. Since...

Scanning electron microscopy studies of the weld decay on SS 304 of water supply pipeline
Open Research DataThis dataset contains micrographs made with scanning electron microscope (SEM) Hitachi S-3400N, of the weld decay for water supply system pipelines made of AISI 304 stainless steel. Within the dataset one can see the different corrosion mechanisms. The micrographs were made after the Strauss test (excluding pictures labeled as pits_in_HAZ, done without...

Changes in psychological distress among Polish medical university teachers during the COVID-19 pandemic
PublicationOur study aims to update knowledge about psychological distress and its changes in the Polish group of academic medical teachers after two years of a global pandemic. During the coronavirus disease, teachers were challenged to rapidly transition into remote teaching and adapt new assessment and evaluation systems for students, which might have been...

Mass spectrometry based identification of geometric isomers during metabolic stability study of a new cytotoxic sulfonamide derivatives supported by quantitative structure-retention relationships
PublicationA set of 15 new sulphonamide derivatives, presenting antitumor activity have been subjected to a metabolic stability study. The results showed that besides products of biotransformation, some additional peaks occurred in chromatograms. Tandem mass spectrometry revealed the same mass and fragmentation pathway, suggesting that geometric isomerization occurred. Thus, to support this hypothesis, quantitative structure-retention relationships...
