Abstract

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.

Abstract

The article presents a precise method for the orientation process of NiMnGa-based single crystals. For this method, a scanning electron microscope equipped with an EBSD camera and a heating stage allowing temperatures exceeding 873 K was used. The orientation process was carried out in both the high-temperature austenite phase and in the room-temperature martensite phase. The facilities allowed for determining the orientation of a single grain of austenite at elevated temperatures as well as the orientation of particular martensitic variants at room temperature. A practically perfect cubic orientation was obtained in the austenitic case with a deviation of about 1° while the samples oriented in the martensitic phase deviated from the desired orientation by 4.5-5.2°. Additionally, the training process of single crystals was carried out in order to show the influence of the orientation process on twinning stress.

Abstract

The purpose of this paper is to examine the mechanisms of classification and discursive representation of the poor and their everyday life, that result in dehumanization and orientalization of their image. Research data (press articles) was analyzed in the framework of theories such as the Bourdieu’s theory of symbolic power, post-colonial studies and discourse theory. The representation of everyday life was analyzed using the theory of real and symbolic localization. The use of the abovementioned theories enabled the author to describe the processes in which the poor are discursively reconstructed as Others. The identity of the “Other” is (falsely) attributed to the poor by localizing them, within the constructed representations of the places they inhabit

Abstract

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.

Abstract

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.

Abstract

17 November 2022 marks the centenary of the death of Jan Grzegorzewski – Orientalist, Slavist, publicist and social activist. The aim of this article is to highlight this figure and to show his activity in various areas of social and scientific life, especially his contribution to Polish Oriental studies. This somewhat forgotten but extremely interesting and colourful, although somewhat controversial, figure has still not received the comprehensive biographical treatment he fully deserves. Thanks to his extraordinary determination and commitment to his activities, Jan Grzegorzewski initiated the establishing of the first Polish scientific journal of Oriental studies, Rocznik Orientalistyczny, for which he also obtained funds. The first part of the first volume of Rocznik, covering the years 1914–1915, was published in 1915 in Cracow, and the second part (for the years 1916–1918) only in 1918. There is also no doubt that with his activities, both academic and journalistic, Jan Grzegorzewski contributed to the establishment of the first Polish Oriental studies in Poland, which took place in 1919 at the Jagiellonian University in Cracow. Analysing some of Grzegorzewski’s achievements from today’s perspective, one can venture to say that with the issues presented in his publications, he undoubtedly inspired many later Orientalists to set new research directions.

Abstract

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.

Abstract

Professor Tadeusz Kowalski (1889–1948) was in correspondence with scholars from practically all over the world. He had an active interest in the developments of Oriental studies in the Soviet Union. He valued the publications he received from the USSR as well as all contacts he had with Russian researchers. He sought to cooperate with Alexander Samoylovich (1880–1938) – one of the most eminent Turkologists in the Soviet Union. This goal had been partially achieved. The archives of the Polish Academy of Sciences and the Polish Academy of Arts and Sciences in Kraków now hold, catalogued under ref. no. K III-4, j. 174, just three letters from the Russian Turkologist. These materials, despite their small number, are an engrossing source of knowledge on the state of Soviet Turkish studies in the mid-1920s and the Soviet Oriental studies community. As the author managed to determine, these letters are all the more precious as the branch of the archives at the Russian Academy of Sciences in St.-Petersburg, where the legacy of professor Samoylovich is kept, has no copies. Interestingly, there are no surviving copies of the letters from professor Kowalski to the Russian Turkologist. This article aims to analyse the contents of the letters written by Alexander Samoylovich, the Soviet Turkologist, to professor Tadeusz Kowalski, and determine the purpose and direction in which Turkish studies were developing in the USSR in the period described in these sources.

Abstract

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).

Abstract

Hope is often treated as a priceless human value anchored in goal-related cognitions. The experiment aimed to investigate whether current hopeful thinking is related to problem-solving performance and how induced goal-oriented thinking influences this problem-solving process. Participants (N = 410) were asked to recall and describe their successful or unsuccessful goal pursuit and complete a scale assessing current hopeful thinking. Subsequently, participants were instructed to (1) think about actions that would be taken to solve the societal problem (i.e., an insufficient number of volunteers in Social Welfare Centers) and (2) describe these actions. In general, people who recalled successful events felt more hopeful than those who recalled unsuccessful events. State Hope was positively correlated with both the quantity (i.e., the total number of solutions) and quality (i.e., usefulness) of participants’ offered solutions. No interaction between State Hope and type of conditions with solution quantity or solution quality was found. State hope, however, interacted with the type of recalled goal pursuit when sex differences were considered. More hopeful women had a better solution quality when they recalled an unsuccessful goal pursuit. For men, a similar pattern was found when they recalled a successful goal pursuit. Lastly, the findings were discussed in light of Snyder’s Theory of Hope.

Abstract

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.

Abstract

In Old Polish texts as well as in later works written in the Old Polish style (e.g. in the Trilogy by H. Sienkiewicz), the name bachmat was used to describe a horse of the Tatar breed, characterized by its small size but incredible endurance. An analogous term ( бахматъ) can be found in the literature of Old Rus’. There is no doubt that it is an orientalism, which entered into both the Old Russsian language and – through it or independently – the Polish language and here from one of the Tatar dialects. Among the explanations for its etymology, the most interesting seems one connecting it with the term Бохмитъ, i.e., a variant of Muhammad’s name, characteristic for the literature of Old Rus’. The article aims to determine when the term бахматъ could have entered the literature of Old Rus’, how widespread it was, in what contexts it appeared, and whether it is possible to show a connection between the studied

Abstract

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.

Abstract

The article presents the results of research on the development of a method for improving the positioning accuracy of an UAV equipped with a single-frequency GPS receiver for determining the linear elements of exterior orientation in aerial photogrammetry. Thus, the paper presents a computational strategy for improving UAV position determination using the SPP code method and the products of the IGS service. The developed algorithmswere tested in two independent research experiments performed with theUAVplatform on which an AsteRx-m2 UAS single-frequency receiver was installed. As a result of the experiments, it was shown that the use of IGS products in the SPP code method made it possible to improve the accuracy of the linear elements to the level of about ±2.088 m for X coordinate, ±1.547 m for Y coordinate, ±3.712 m for Z coordinate. The paper also shows the trend of changes in the obtained accuracy in determining linear elements of exterior orientation in the form of a linear regression function. Finally, the paper also applies the SBAS corrections model for the improvement of UAV position calculation and determination of linear elements of exterior orientation. In this case, the improvement in the accuracy of determining the linear elements of exterior orientation is about ±1.843 m for X coordinate, ±1.658 m for Y coordinate, ±7.930 m for Z coordinate. As the obtained test results show, the use of IGS products and SBAS corrections in the SPP code method makes it possible to improve the determination ofUAVpositions for the use in aerial photogrammetry. Keywords: UAV, GNSS measurements, linear elements of exterior orientation, accuracy.

Abstract

The main goal of estimating models for industrial applications is to guarantee the cheapest system identification. The requirements for the identification experiment should not be allowed to affect product quality under normal operating conditions. This paper deals with ensuring the required liquid levels of the cascade system tanks using the model predictive control (MPC) method. The MPC strategy was extended with the Kalman filter (KF) to predict the system’s succeeding states subject to a reference trajectory in the presence of both process and measurement noise covariances. The main contribution is to use the application-oriented input design to update the parameters of the model during system degradation. This framework delivers the least-costly identification experiment and guarantees high performance of the system with the updated model. The methods presented are evaluated both in the experiments on a real process and in the computer simulations. The results of the robust MPC application for cascade system water levels control are discussed.

Abstract

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.

Abstract

The article presents the two known Poland-related statements by the Hungarian Orientalist Arminius Vámbéry (1832–1913), who explained his opinion on the possible independence of a Polish state twice – in 1898 and 1906. In 1898, he was interviewed by the Budapest correspondent of the Kraków-based Polish newspaper Nowa Reforma. In 1906, he answered an international survey by the cultural journal Krytyka, based in Kraków as well. Vámbéry’s answer to the question of whether Poland should gain independence once again was positive. Still, he justified the necessity of Polish independence not with the interests of the Polish people but with Europe’s wish to be protected from the Russian Empire: to Vámbéry’s mind, an independent Poland should serve as Europe’s bulwark against the Russian enemy. Vámbéry’s fear of the Russian Empire might be in line with his previous views on the Great Game, the rivalry between the Russian Empire and Great Britain on influence in Central Asia, and the European public opinion at the end of the 19th century.

Abstract

In the article the author deals with the years the famous Turkologist and historian Ahmet Zeki Velidi Togan (1890–1970), who is known for his great edition of the 10th-century Arabic travel account of Ibn Faḍlān was working and teaching at Rheinische Friedrich- Wilhelms-Universität in Bonn (1935–1938). Various documents relating to events from this period are reproduced in the article (including his appointment to the Oriental Seminar at the university, his appointment as a member of the Finno-Ugric Society in Helsinki, his appointment as an honorary professor, a research stay in Turkey, his leave of absence to carry out a lectureship at the Georg August University in Göttingen, and finally his defence in response to accusations regarding his “political reliability”, which are not known in detail. This defence was made both by Paul Kahle and by himself in the form of an account of his political activities in the years 1917–1929, the full text of which is appended and which was later also used by Togan himself in his autobiography.

Abstract

Fruit flies belonging to the Bactrocera dorsalis species complex pose a significant threat to mangoes and other crops in the Philippines and worldwide. Identifying cryptic species within this complex is challenging, particularly when relying solely on morphological analysis. In this study, we sequenced two fragments of the nuclear 18S and ITS2-28S rRNA genes from specimens of Bactrocera dorsalis Hendel collected in the Philippines to assess their applicability for species diagnostics. Subsequent sequencing and analysis revealed that the 18S and 28S rRNA gene fragments matched B. dorsalis sequences in NCBI but also displayed high similarity with other Bactrocera and insect species. On the other hand, sequences of the ITS2 segment showed hits specific to B. dorsalis. Further analysis of the 18S rRNA gene in fruit flies collected from various sources and host plants in the country suggests conserved sequences among Bactrocera samples, irrespective of collection site and host plant species. In conclusion, our findings suggest that, among the tested nuclear DNA fragments, only the ITS2 demonstrates sufficient species-level nucleotide variation for effective use as a molecular diagnostic marker for B. dorsalis identification.

Abstract

Orhan Pamuk, the winner of the Nobel Prize in Literature in 2006, is one of the most interesting and versatile of contemporary writers whose prose contributes to the understanding of the cultural background of the Orient and the Occident forged out of the juxtaposition of Islam and Christianity. As a might-have-been artist, who is currently an amateur photographer, the author, in an uncommon way, visualizes the continual wonder towards colors in the surrounding reality featuring in his fictional and non-fictional texts. The most important aspects of Pamuk’s works, however, are the journeys near and far and those within oneself, as well as the wanderings through cities, especially those of his native Istanbul. Aside from the returns home and to the motherland, Pamuk contrasts the inspiring voyages out with the voyages into the collective and individual past, in all their historical and political complexity. The present paper is an overview of Orhan Pamuk’s works from the perspective of colors and the aforesaid passages, which remind his readers of travelling as a basic topos of the course of human existence.

The paper examines Edward Said's critique of Thomas Edward Lawrence view on Arabs and Arabian culture and society. On the one hand some of Said's allegations seems poorly grounded and can be deny with some excerpts from Lawrence's Seven Pillars of Wisdom. On the other hand Said doesn't remark serious shortcomings of Lawrence's outlook of intercultural relations.

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).

Abstract

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.
