The state of development, the existing and emerging forms of development, the intensity and legibility of settlement systems, all this is essential for the living conditions of urban residents, their surroundings and peripheral systems. The purpose of the article is to assess the accessibility to market and public services by estimating the distance to these services from housing facilities in Poland. The use of the residential dispersion ratio (RDR) and an analysis of the spatial distribution of municipalities with the highest values of the coefficient allows to identify areas where accessibility to public and market services is weak.
The study presents a change in the innovation model and a change of development path towards new industries and modernization of traditional industries in the Pomeranian Voivodship. The characteristics of the region and the characteristics of the regional innovation system based on statistical data, existing research, analysis and interviews with representatives of regional and local authorities, scientists and entrepreneurs of the voivodship were presented. The factors that preceded the change of the innovation model and direct causes of change were identifi ed aa well as the impact of institutional factors and the barriers to the development of the voivodship.
The topic of the article is a description of European urbonyms which fulfilled both political and commemorative roles in the past. The city names are presented in chronological order starting from ancient times to the 20th century. The ancient toponyms are related to the expansion of the Roman Empire, and the names of Roman emperors are used as a foundation for these toponyms. Such urbonyms created on the outskirts of the Roman Empire made reference to their new political allegiance and confirmed it. These naming practices therefore played an important role in the process of territorial expansion and the consolidation of political control. This naming model was also present in Byzantium, and became popular on the outskirts of medieval Ruthenia under the influence of the Byzantine Empire. The tradition of commemorating political rulers through toponyms stayed constant in the Eastern Slavic regions, and was continued by the Russian monarchy as well as the USSR. Such naming practices were initially used as a tool for the structural organisation of Kievan Rus’, and later to erase foreign names from these regions of Tsarist Russia. In Communist times, this tradition reaffirmed the new political reality through the use of surnames of political figures in toponyms. In the 20th century there was an increase in surnames featured in urbanonyms (the names of streets, squares, housing estates). This increase was meant to preserve the memory of remarkable individuals in society.
W kopalniach podziemnych w wyniku wykonywania różnego rodzaju wyrobisk, na osuwiskach ziemi podczas ich aktywnych ruchów a także w czasie trzęsień ziemi dochodzi do zmian pierwotnego pola naprężenia i deformacji górotworu. Górotwór lub materiał skalny poddawany różnego rodzaju obciążeniom ulega deformacji trwałej i jest źródłem różnego rodzaju fal sejsmicznych, emisji sejsmoakustycznej (SA) i elektromagnetycznej (EM). W artykule przedstawiono wyniki badań laboratoryjnych emisji elektromagnetycznej w czasie jednoosiowego ściskania próbek skalnych. Uzyskane wyniki pomiarów emisji EM oraz emisji SA wskazują na ich silny związek ze stopniem obciążenia badanej próbki skalnej. W analizie otrzymanych wyników stwierdzono, że emisja EM dokładniej odzwierciedla stan naprężenia i deformacji w próbce w porównaniu do emisji SA. Można wnioskować, iż opracowanie systemu obserwacyjnego opartego o pomiar emisji EM może być przydatny w wyrobiskach górniczych do oceny zagrożeń związanych z obciążaniem skał. System taki powinien pracować bezinwazyjnie oraz charakteryzować się niskim kosztem i nieskomplikowaną obsługą. Budowa takiego sytemu może wspomagać stosowane powszechnie systemy geofizyczne w kopalniach.
In this publication, the strategy of land resources administration is presented on the basis of consideration of proposed result factors. The research methodology is based on the use of the PESTLE analytical model in conjunction with economic-mathematical modeling. The scientific novelty of the publication is developing the technology of administration of land resources on the basis of cadastral and other statistical information, which allows obtaining scientifically grounded solutions on the use of land resources. Considering the process of Land Resources Administration as a procedure based on making certain decisions when creating a management system which takes into account the internal and external relationships in this system, the postulate is about determining the degree of trust in this system, establishing economic, environmental and social risks when using it. To a certain extent, the process of Land Resources Administration is a prediction of the effective use of this natural potential in the future. It should be noted that the reliability of the forecast decision depends on the nature and parameters of uncertainties and the duration of their validity. Consequently, while making operational decisions on land resources for a short perspective, the forecasting is more reliable than for a long one. It becomes an effective mechanism of objective evaluation of the state of land resources and the prospects for their use. In this publication the main influencing decision making factors and the technological scheme of the solution of the problem are given.
The Committee on Acoustics of the Polish Academy of Sciences was founded in 1964 by the reso lution of the General Assembly of the Polish Academy of Sciences, within its Division of Engineering Sci ences (Division 4). The idea of creating the Committee was brought up by Professor Ignacy Malecki, a distinguished scientist, an academic teacher, and an internationally acclaimed authority on acoustics.
The increased cultivation of highbush blueberry in Poland has been paralleled with enhanced
damage to this crop by different pests and diseases, including soft scales. We have
carried out trials to assess methods for controlling soft scales of the genus Parthenolecanium
in highbush blueberry grown in open fields or under a plastic tunnel, with an approach
based on integrated pest management (IPM) principles. The reduction of Lecanium
scale population using alternative products, with mechanical mechanisms of action, was
similar to that achieved with treatments of different formulations of neonicotinyl-based
pesticides; sometimes they were even more effective on protected crops. Control programs
on plantations with a large population of Lecanium scales based on the application of these
alternative products in spring and at harvest time and chemical compounds in autumn resulted
in a very high efficacy and are considered the most suitable strategies to assure yields
without residues and a reduced impact on the environment.
The article presents a shock safety model of an indirect contact with a low-voltage electric device. This model was used for computations and analyses concerning the following: the probabilities of appearance of the particular shock protection unreliability states, electric shock states (ventricular fibrillation), contributions of the unreliability of different shock protection elements to the probability of occurrence of these states, as well as the risk of electric shock (and the shock safety), and contributions of the intensity of occurrence of damages to different shock protection elements to this risk. An example of a possibility to reduce the risk of an electric shock through changing the intensity of occurrence of damages to the selected protection elements was provided.
A one-dimensional transient mathematical model describing thermal and flow phenomena during coal coking in an oven chamber was studied in the paper. It also accounts for heat conduction in the ceramic oven wall when assuming a constant temperature at the heating channel side. The model was solved numerically using partly implicit methods for gas flow and heat transfer problems. The histories of temperature, gas evolution and internal pressure were presented and analysed. The theoretical predictions of temperature change in the centre plane of the coke oven were compared with industrialscale measurements. Both, the experimental data and obtained numerical results show that moisture content determines the coking process dynamics, lagging the temperature increase above the water steam evaporation temperature and in consequence the total coking time. The phenomenon of internal pressure generation in the context of overlapping effects of simultaneously occurring coal transitions - devolatilisation and coal permeability decrease under plastic stage - was also discussed.
A variety of algorithms allows gesture recognition in video sequences. Alleviating the need for interpreters is of interest to hearing impaired people, since it allows a great degree of self-sufficiency in communicating their intent to the non-sign language speakers without the need for interpreters. State-of-theart in currently used algorithms in this domain is capable of either real-time recognition of sign language in low resolution videos or non-real-time recognition in high-resolution videos. This paper proposes a novel approach to real-time recognition of fingerspelling alphabet letters of American Sign Language (ASL) in ultra-high-resolution (UHD) video sequences. The proposed approach is based on adaptive Laplacian of Gaussian (LoG) filtering with local extrema detection using Features from Accelerated Segment Test (FAST) algorithm classified by a Convolutional Neural Network (CNN). The recognition rate of our algorithm was verified on real-life data.
The text is devoted to the reconstruction of Wolniewicz’s philosophical views presented by him in the first volume of his Philosophy and Values. The philosophical tradition to which Wolniewicz admitted allegiance and the results of his analyzes in the field of methodology, philosophy of religion, anthropology and philosophy of politics are discussed. Some methodological problems are raised, such as theoretical criteria (including the semantic criterion) of theoreticity, philosophy as theory, philosophical styles, parapsychology as a pseudo-theory, mystified observation and the rule of rationality. Within philosophy of religion the author analyses Wolniewicz’s thesis that the foundation of religion resides in the fear of death. From anthropological problems, Wolniewicz’s views on relations of anthropology to axiology are presented, as well as the relationship between meliorism and pejorism (with particular emphasis on the so-called epiphany of the devil), abortion and murder, transplantations and ‘(neo)cannibalism.’ Within philosophy of politics the author undertakes to carefully reconstruct Wolniewicz’s attempts to distinguish between such oppositions as democracy and democratism, evolution and revolution, fanaticism and tolerance. Finally the author argues that Wolniewicz was one of the most outstanding contemporary Polish philosophers even though he points to some gaps in his arguments.
The paper presents the problem of assessing the accuracy of reconstructing free-form surfaces in the CMM/CAD/CAM/CNC systems. The system structure comprises a coordinate measuring machine (CMM) PMM 12106 equipped with a contact scanning probe, a 3-axis Arrow 500 Vertical Machining Center, QUINDOS software and Catia software. For the purpose of surface digitalization, a radius correction algorithm was developed. The surface reconstructing errors for the presented system were assessed and analysed with respect to offset points. The accuracy assessment exhibit error values in the reconstruction of a free-form surface in a range of ± 0.02 mm, which, as it is shown by the analysis, result from a systematic error.
