  - JOURNAL OF TRANSPORTATION ENGINEERING-ASCE - Year 2012

  W pracy przedstawiono rezultaty zastosowania ciągłych pomiarów satelitarnych toru kolejowego, z antenami zainstalowanymi na poruszającym się pojeździe szynowym. Wykazano, że zastosowana pilotażowo technika pomiarowa umożliwia bardzo precyzyjne określenie podstawowych danych do projektowania modernizacji linii kolejowej (kierunków głównych trasy i jej kąta zwrotu), a także - ze stosunkowo niewielkim błędem - współrzędnych istniejącej...

  Electronic noise has its roots in the fundamental physical interactions between matter and charged particles, carrying information about the phenomena that occur at the microscopic level. Therefore, Low-Frequency Noise Measurements (LFNM) are a well-established technique for the characterization of electron devices and materials and, compared to other techniques, they offer the advantage of being non-destructive and of providing...

  - HYDROACOUSTICS - Year 2007

  There is a growing interest in digital transmission of telemetry data on ultrasonic waves. The dependence of signal attenuation on squared frequency, specific to the hy-droacoustic systems, induces problems that do not exist in monochromatic, narrowband radio communications systems. For adapting the transmission parameters to current propagation conditions, a precise knowledge of instantaneous changes of channel performances is...

  - SENSORS - Year 2020

  The article presents the influence of the camera and its optical system on the uncertainty of object position measurement in vision systems. The aim of the article is to present the methodology for estimating the combined standard uncertainty of measuring the object position with a vision camera treated as a measuring device. The identification of factors affecting the location measurement uncertainty and the determination of their...

  This paper presents a new method of fault loop resistance measurement in low voltage systems with residual current devices. The method enables measuring fault loop resistance without nuisance tripping of residual current devices, by application an unconventional waveform of measurement current. It is important for proper verification of the effectiveness of protection against electric shock.
