Opis:: Modern agriculture involves the implementation of a particular technological operation, according to the appropriate map-task, which is developed pre-based on diverse information. Knowledge of a certain structure of soil cover variability, obtained using information and technical systems of local operational monitoring of agro-biological state of agricultural lands, allows us to adopt effective operational decisions for efficient management of agro-biological potential of agricultural lands. Obviously, under such conditions, there is a need for fundamentally new approaches to agricultural production,which is to ensure the proper quality of technological operations. The quality of the implementation of technological operations is an integral indicator of the efficiency of production of agricultural products within the agro-biological field. The necessary quality of implementation of the basic technological processes in plant growing is provided by the integrated information and technical systems of operational monitoring of the agro-biological state of agricultural lands. In connection with this, the task is to obtain reliable data on the agro-biological state of the soil environment by reducing the error in determining the magnitude of the conductive properties of the soil, providing individual stabilization of the working electrodes and the mechanism of lifting / lowering working electrodes, copying inequalities of the soil environment, reducing the intensity of the destruction of the soil structure , self-cleaning of the working contact of the electrode and ensuring the stability of the electrical contact of the electrode with the soil, by instrument design perfection. The task is achieved by using the information and technical system of operational monitoring of the soil environment of the structure to determine the conductive characteristics of the soil environment.

Opis:: Available techniques for dealing with uncertainties in the agro-industrial complex and their use for describing and assessing the adequacy of the decisions taken are incomplete, and often ineffective, as they usually do not take into account the combination of "field-machine-technological material", which prevents acceptance effective solutions for managing agro-biological potential of agricultural land and, as a consequence, obtaining the maximum economic efficiency of agricultural production. Reliable estimation of variables of agricultural production parameters using the "field-machine-technological material" model makes it possible to provide optimal control of available technical equipment (machinery, sowing machines, etc.), agro-biological (humus content, presence of nutrients, micro-and macro elements, etc. in soil or plant ) and technological resources for making adequate decisions and managing agro-biological potential of agricultural lands, which will provide the necessary economic efficiency. The task is achieved by ensuring the proper quality of the implementation of technological operations that are an integral indicator of economic efficiency and allow providing the necessary economic efficiency through optimal and efficient management of technical means for optimal action on the agro-biological potential of the field and the use of available technological resources. Such control is possible with the use of information and technical systems of local operational monitoring, which are located on machine-tractor units and provide effective control of technological operations by acting on the executive bodies of agricultural machines on the basis of data characterizing the agro-biological state of the soil environment. Information and technical systems of local operational monitoring of the agro-biological state of agricultural lands are used in the following cases: - before performing a technological operation, - simultaneously with the implementation of the technological operation (sowing, fertilizer application, etc.), - during the growing season and after harvesting. This opens new prospects for organic farming using such "smart" agricultural machines.

Opis:: In the article, a brief review is presented of the definition of meteorological and agricultural droughts, drought indices and the operational systems of monitoring droughts in Poland. Drought is a widespread and frequent disaster which occurs more often within humid climate zones. Meteorological drought is the result of deficiencies in precipitation. Agricultural drought is an effect of various characteristics of meteorological and hydrological drought in agriculture comprising the reduction of evapotranspiration, soil water deficits, and reduced crop yield. Drought indicators are the common measures for drought assessment. The paper contains an inventory of drought measures (indicators) that are applied to evaluate meteorological and agricultural drought in Poland. For meteorological drought monitoring and the assessment of its intensity, four different indices have been used in Poland: relative precipitation index (RPI), effective drought index (EDI), standardised precipitation index (SPI) and climatic water balance (CWB). Agricultural drought is monitored by soil moisture index (SMI), agricultural drought index (CDI) and the potential reduction of final yield (yield reduction ratio YR). The working drought monitoring systems give information for the whole country or for a specific region but they are directed to some specific drought analyses. Four different drought monitoring systems have been under operation in Poland since 2005. The Institute of Meteorology and Water Management (IMGW) conducts the system called “POSUCH@”. The Institute of Soil Science and Plant Cultivation conducts the agricultural drought monitoring system. The Institute of Technology and Life Sciences (ITP) has developed two systems: the regional drought monitoring system in the Kujawy region and the nationwide system of monitoring and forecasting water deficit and surplus in agriculture.

Opis:: This paper presents the results of experimental and numerical studies on reliability and monitoring issues of railway infrastructure in terms of safety and operation. The state of knowledge concerning methods of assessing track condition, in particular rail joints used in continuous welded rail track of railway lines is described. Experimental results of rail joints used in track transition zones and the results of numerical studies/tests of the rail vehicle-track model are outlined. It is demonstrated, basing on the analyses of the experimental results, that not only should the rail joints used in continuous welded rail track be diagnosed during their acceptance, but also during their operation. It is proven that the currently used methodology for testing welded rail joints applied during acceptance testing of contact track is not fully correct and leads to misinterpretation of the measurement results. Moreover, the results of numerical simulation tests presented in this paper confirm the possibility of diagnosing the condition of rail joints by any vehicle passing over such a track equipped with a suitable system.

Opis:: Vibrations of wind turbines strongly depends on the wind. For the purpose of wind turbines condition monitoring it is very important to understand the nature of the wind, especially its time variability. The paper investigates fundamental statistics of the wind and vibrations for four wind turbines in two wind farms. Seasonal and diurnal variations are presented and discussed. For both vibration and wind speed seasonal trends are clearly visible, particularly for mean values, but also for standard deviation. Variability of vibration and wind are compared using mean/std ratio. The results can be helpful to determine operational states of wind turbines. It can also help achieve comparable results of technical state assessment for different machines located in different locations.
Wibracje w turbinach wiatrowych zależą w znacznym stopniu od wiatru. Zrozumienie natury wiatru jako zjawiska, szczególnie jego zmienności, jest istotne dla skutecznej diagnostyki turbin wiatrowych. Artykuł opisuje podstawowe dane statystyczne prędkości wiatru oraz wibracji dla czterech turbin wiatrowych z dwóch różnych farm. Opisane są zmiany sezonowe i dzienne. Trendy sezonowe są widoczne zarówno w przypadku prędkości wiatru jak i poziomu wibracji, szczególnie w przypadku wartości średnich, ale także, do pewnego stopnia, dla odchyleń standardowych. Zmienności wibracji i prędkości wiatru są porównane przy pomocy współczynnika mean/std. Wyniki będą pomocne przy ustalaniu stanów operacyjnych turbin, a także przy ocenie stanu technicznego dla turbin zlokalizowanych w różnych lokacjach.

Opis:: The paper is an overview of selected ways of increasing the operational flexibility of steam units, which are predominant in the Polish power system. These studies were prompted by the dynamic changes in the structures of installed capacity and generation output in the National Power System due to a rapid increase in the number of wind turbines in the country. The methods of thermal unit operational flexibility improvement are divided into two groups. The first group comprises solutions with heat and mass storage as well as chemical energy storage. These are solutions to manage the auxiliary load of units regardless of system load. The second group consists of methods for an off-design increase in the safe level of thermal energy machine design stress. The development of numerical tools using complex methods of thermal stress determination, such as Burzyński-Pęcherski’s theory, combined with advanced on-line machine diagnostics, allows for an extension in the operational range of a machine, beyond the original safe operation limit without risk of damage or loss of service life, in other words.
W pracy przedstawiono przegląd wybranych sposobów zwiększania elastyczności pracy bloków parowych, które stanowią największą siłę wytwórczą w polskim systemie elektroenergetycznym. Motywacją do podjęcia prac w tym kierunku są dynamiczne zmiany w strukturze mocy zainstalowanej i energii wytwarzanej w Krajowym Systemie Elektroenergetycznym związane z szybkim wzrostem liczby siłowni wiatrowych na terenie kraju. Metody poprawy elastyczności pracy bloków cieplnych podzielono na dwie grupy. Pierwszą grupę stanowią rozwiązania wykorzystujące magazyny ciepła i masy oraz magazyny energii chemicznej. Są to rozwiązania pozwalające kształtować obciążenie potrzeb własnych bloku niezależnie od obciążenia systemu. Drugą grupę stanowią metody pozwalające na pozaprojektowe wytężanie konstrukcji maszyn cieplnych. Rozwój narzędzi numerycznych wykorzystujących złożone metody wyznaczania naprężeń cieplnych, takie jak np. teoria Burzyńskiego–Pęcherskiego, w połączeniu z zaawansowanymi systemami diagnostyki maszyn online, umożliwiają wychodzenie z pracą maszyn poza granice tzw. bezpiecznej pracy bez ryzyka uszkodzeń lub utraty żywotności.
