    Opis:
    In the safety assessment of hydro-technical objects, it is necessary to combine different measurement techniques, calculations and experience of specialists in various fields of engineering. That is possible due to the current development of surveying technology. Undoubtedly, the integration of measurements, including technical assessment as well as object behaviour modelling, makes it possible to perform more comprehensive assessment of objects. Nevertheless, in order to obtain a multidimensional overview of an examined object – especially water dam – it is necessary to know all the possible errors that appear along the “observer-instrument-object” path. In this paper, the authors intended to investigate the influence of atmospheric conditions on the results of geodetic deformation measurements and attempted to consider surface deformation analysis, which is part of obligatory inspections of hydro-technical objects. The study was based on the geometry assessment of the vent wall of Rożnów water dam located within the borders of the South-Polish Protected Landscape Area. The measurements took place in the years 2013‒2015 and were performed using Z + F Imager 5010 laser scanner equipped with an integrated thermal camera. Surveying results and analyses based on archival data and forecasts of atmospheric conditions at the location of the hydro-technical facility can be applied while elaborating the rules for a control date selection. The proper definition of a measurement cycle will make it possible to avoid errors of interpretation for those facilities important from the flood protection, recreation and nature perspectives.

    predictive maintenance
    Opis:
    In the present paper we focus on online monitoring system for predictive maintenance based on sensor automated inputs. Our subject was a device from Maritsa East 2 power plant - a mill fan. The main sensor information we have access to is based on the vibration of the nearest to the mill rotor bearing block. Our aim was to create a (nonlinear) model able to predict on time possible changes in vibrations tendencies that can be early signal for system work deterioration. For that purpose, we compared two types of recurrent neural networks: historical Elman architecture and a recently developed kind of RNN named Echo stet networks (ESN). The preliminary investigations showed better approximation and faster training abilities of ESN in comparison to the Elman network. Direction of future work will be increasing of predications time horizon and inclusion of our predictor at lower level of a complex predictive maintenance system.

    Opis:
    This paper presents techniques which base on the concept of flows thinning together with the identification techniques. These methods are proposed to determine the expected number of failures to assess the efficiency of technical diagnostics of instruments. Additionally, this research focuses on the improvement of multi-machine troubleshooting systems, based on the ‘AND-OR’ graphs. Respective algorithms are presented. The majority principle uses the input information to check the correctness of the decision regarding identification of faulty machines. In this paper we base on the complete testing algorithm for elements of multi-computer complexes searching by criteria of failed element.
