The given article is an analysis of Władysław Wężyk’s Travels to the ancient world taking into consideration the most important problems and components of the 19th century Romantic worldview. Particular attention will be paid to the great Romantic themes such as folklore, art, music, spontaneous literary works and concepts of new humanity. Wężyk’s memoir reveals his openness towards the Other and the understanding of foreign cultures which is by far the most important feature of a Romantic intellectual.
The aim of the article is an attempt to reconstruct a description of the image of Arab World on the basis of selected (yet representative) writings from the second half of the 18th century. In that period, due to the trending Enlightenment orientalism understood as a fascination with the Orient and references made to it in the culture, the Arab world appeared among Polish representatives of the Age of Reason. These trends were expressed in art, customs, literature and – in the form of various concepts and images – in social consciousness. These images differed between each other both in terms of content and form. Some of them aimed to depict the Arab world objectively and extensively, whereas the other, on the contrary, were merely delineations focused on particular elements of the Arab world, depicting only one or a few aspects. Some of them, such as the image of Arabia Felix or utopian reminiscences refer to the tradition and update it. Some of them were created for the time being. Nevertheless, each of them reflects the topics, problems and questions which concerned the minds in Enlightenment Poland. Moreover, relatively high correlation between European archetypes and the image of the Arab world which occurs in the writings of the Polish Enlightenment confirms that Poland belongs to the Old Continent cultural group, which was crucial for the promoters of Polish Enlightenment.
This paper presents results of object-oriented classification of Landsat ETM+ satellite im-age conducted using eCognition software. The classified image was acquired on 7 May 2000. In this particular study, an area of 423 km2 within the borders of Legionowo Community near Warsaw is considered.
Prior to classification, segmentation of the Landsat ETM+ image is performed using panchro-matic channel, fused multispectral and panchromatic data. The applied methods of classification en-abled the identification of 18 land cover and land use classes. After the classification, generalization and raster to vector conversion, verification and accuracy assessment are performed by means of vis-ual interpretation. Overall accuracy of the classification reached 94.6%. The verification and classifi-cation results are combined to form the final database.
This is followed by comparing the object-oriented with traditional pixel-based classification. The latter is performed using the so-called hybrid classification based on both supervised and unsuper-vised classification approaches. The traditional pixel-based approach identified only 8 classes. Com-parison of the pixel-based classification with the database obtained using the object-oriented ap-proach revealed that the former reached 72% and 61% accuracy, according to the applied method.
The article deals with the appropriation of postcolonial studies to look at Central Europe and Galicia. Beginning with the concept of“internal colonialism“, we follow the evolution of postcolonial theory from a basically economy-based concept into a poststructuralist cultural theory, presenting the development and uses of its central concepts, such as Orientalism or othering. Based on some examples, we also highlight its previous appropriation to Central Europe and the political implications it carries in this region.
In the article the author discusses the relationship between education and socio-cultural needs. The socio – cultural reality is the reality of a permanent change. It is difficult to describe and even more difficult to understand. The specific character of qualitatively new changes in the relations between globality and locality implies a completely new perception of reality, ways of interpreting the world, and a new quality of judgments about the condition of the modern man. This reality is also a ”multiplicity of worlds”, which means a large number of possibilities to create oneself. What individuals perceive as their ”own” has the biggest developmental potential when it is worked out on the proactivity path. proactive people are distinguished by interrelated features: the search for a possibility of change (the environment examination, going beyond limitations of a given situation), establishing effective and change oriented goals (opening new paths of action), foreseeing problems and remedia measures (the analysis of one’s own achievements, looking for signals of threats or dangers), looking for new ways of achieving goals (the ambition is to make a new tradition).
The study considers remittances as part of the lifeworlds of immigrants in multiple interactions with return intentions and communication with those left behind. This is an alternative view of the standard approach to remittances as a possible source of development or as a variable to be explained by family solidarity, investment projects or the reasons for return. The key dependent variable is the home orien-tation of immigrants as a function of remittances, return intentions and communication behaviours, measured in quantitative and typological terms. The typological analysis of home orientation diverges from the standard approach, which is in terms of high or low intensity of cross-border activities of remitting or communicating between immigrants and those they have left behind. It argues for the fact that cross-border activities combine in different ways to generate specific social types of remitting prac-tices. The remitting behaviours of migrants are, in our approach, multidimensional, encompassing eco-nomic, social and cultural content. Three hypotheses are formulated on: 1) collective deprivation in remitting money; 2) survival–development–identification strategies of migrants’ families; and 3) higher predictability of home orientation compared to economic remitting behaviours. In this context, higher predictability means greater variation of the synthetic variable of home orientation by social, cultural and economic factors as compared to the impact of the same factors on the more abstract variable of economic remittances.
Propagation of linearly polarized light beams in a nematic liquid crystal cell with distinguished regions of different molecular orientation has been analyzed. Specifically, combination of the planar/homogenic and homeotropic alignment, forming thus spatially limited regions characterized by a different LC molecular orientation, has been tested, as achieved by means of the photo-orientation and photo-polymerization processes, independently. An influence of molecular orientation on the light beam propagation has been checked for different directions of the linear polarization. Thanks to the molecular reorientation induced by the low frequency external electric field and also to the reorientational nonlinearity taking place in NLCs, propagation direction of the light beam can be additionally controlled by the electric bias and/or optical power, respectively. Proposed structural solutions and techniques, related to the photo-orientation and photo-polymerization processes described in this communication, give rise to the novel LC geometries and structures. The latter act as promising candidates for new practical photonic applications as they are expected to be of a particular importance for integrated optic elements and devices.
In this paper deep neural networks are proposed to diagnose inter-turn short-circuits of induction motor stator windings operating under the Direct Field Oriented Control method. A convolutional neural network (CNN), trained with a Stochastic Gradient Descent with Momentum method is used. This kind of deep-trained neural network allows to significantly accelerate the diagnostic process compared to the traditional methods based on the Fast Fourier Transform as well as it does not require stationary operating conditions. To assess the effectiveness of the applied CNN-based detectors, the tests were carried out for variable load conditions and different values of the supply voltage frequency. Experimental results of the proposed induction motor fault detection system are presented and discussed.
We demonstrate a modularity bug in the interface system of Java 8 on the practical example of a textbook design of a modular interface for vector spaces. Our example originates in our teaching of modular object-oriented design in Java 8 to undergraduate students, simply following standard programming practices and mathematical denitions. The bug shows up as a compilation error and should be xed with a language extension due to the importance of best practices (design delity).
A simple empirical study on the orientation, diameter, and extent of radial fractures (long and short) at the vicinity of the face-perpendicular preconditioned boreholes is described. Homogenous and heterogeneous mining faces were considered when studying the orientation of radial fractures, four and five face-perpendicular preconditioning practices were used to investigate the outspread and diameter of radial fractures from one blasted drill hole to another. Long radial fractures were observed to be developed along the direction of the maximum principal stress and short radial fractures were observed to be developed along the direction of the intermediate principal stress in a homogenous mining face. On the other hand, long radial fractures were observed to be developed along the direction of the intermediate principal stress, while short radial fractures were observed to be developed along the direction of the maximum principal stress when the mining faces subjected to heterogeneous rock mass. The diameters of the radial fractures observed were inconsistent and were not nine times the diameter of the original borehole. Furthermore, the extent of radial fractures from one borehole to another was noted to be gradually improved when the additional of preconditioned borehole was in place. This study maintained that the orientation of radial fractures is mostly controlled by the rock properties, however, extend and the diameters of the radial fractures are controlled by rock properties, the effectiveness of the stress wave and gas pressure and brittleness of the rock mass.
