Determining horizontal curvature of railway track axis in mobile satellite measurements
PublicationThe article discusses the applicability of a novel method to determine horizontal curvature of the railway track axis based on results of mobile satellite measurements. The method is based on inclination angle changes of a moving chord in the Cartesian coordinate system. In the presented case, the variant referred to as the method of two virtual chords is applied which consists in manoeuvring with only one GNSS (Global Navigation...

Impact assessment culture in the European Union. Time for something new?
PublicationCurrent approaches and cultures for the economic evaluations of environmental and health policies may suffer from excessive reliance on a standard neoclassic economic toolbox that neglects alternative perspectives. This may prematurely limit the spectrum of available policy options. Here we show how the inclusion of neglected currents of thought such as non-Ricardian economics, bioeconomics and a set of qualitative-quantitative...

Digital Filtering of Railway Track Coordinates in Mobile Multi–Receiver GNSS Measurements
PublicationThe article discusses an important issue in connection with the technique of mobile Global Navigation Satellite System (GNSS) measurements of railway track coordinates, which is digital filtering performed to precisely determine railway track axes. For this purpose, a measuring technique is proposed which bases on the use of a measuring platform with a number of appropriately distributed GNSS receivers, where two of them determine...

Rozpoznawanie ruchów i gestów wykonywanych ustami w obrazie wizyjnym z użyciem sieci neuronowych
PublicationUstomysz jest interfejsem komputerowym, umożliwiającym sterowanie kursorem ekranowym za pomocą ruchów ust i gestów wykonywanych ustami. Główną grupą docelową użytkowników interfejsu są osoby, które z dowolnego powodu nie mogą lub nie chcą posługiwać się tradycyjną klawiaturą i myszką komputerową. W związku z tym, może on umożliwić osobom niepełnosprawnym ruchowo, np. z niedowładem kończyn posługiwanie się komputerem, a przez to...

Testing the Positioning Accuracy of GNSS Solutions during the Tramway Track Mobile Satellite Measurements in Diverse Urban Signal Reception Conditions
PublicationMobile Global Navigation Satellite System (GNSS) measurements carried out on the railway consist of using satellite navigation systems to determine the track geometry of a moving railway vehicle on a given route. Their purposes include diagnostics, stocktaking, and design work in railways. The greatest advantage of this method is the ability to perform measurements in a unified and coherent spatial reference system, which...

Application of Least Squares with Conditional Equations Method for Railway Track Inventory Using GNSS Observations
PublicationSatellite geodetic networks are commonly used in surveying tasks, but they can also be used in mobile surveys. Mobile satellite surveys can be used for trackage inventory, diagnostics and design. The combination of modern technological solutions with the adaptation of research methods known in other fields of science offers an opportunity to acquire highly accurate solutions for railway track inventory. This article presents the...

Physical modeling in sands in a wide range of stress level: Application to the calibration of CPTU i DMT tests.
PublicationPraca dotyczy badań modelowych w gruntach niespoistych ze szczególnym uwzględnieniem wpływu wysokiego poziomu naprężenia na zachowanie się podłoża gruntowego. Praca składa się z siedmiu rozdziałów. W pierwszym z nich opisano zachowanie się piasku w szerokim zakresie naprężeń z uwzględnieniem ściśliwości, kruszenia się ziaren, nieliniowości obwiedni zniszczenia oraz nieliniowości modułu odkształcenia związanych z poziomem naprężenia...
