Application of interpolated discrete fourier transform method in the diagnostics of cage induction motors
Get PDFThis paper compares the accuracy of the multi-frequency stator phase current spectrum estimation. This is as a development of considerations made in [1]. In this paper, the authors added to previous results for the classic Discrete Fourier Transform method and the two-point interpolated DFT method (IpDFT ), new results obtained by three-point IpDFT method’s algorithm. The analysis was made for slip spectrum component which is used for cage damage detection. To minimize the spectrum leakage effect, the selected Rife-Vincent Class I windows (RVCI ) were used. The article focuses on the effectiveness of spectral component estimation in function of the used method, type of time window and measurement time. Values of errors of frequency and amplitude estimations are presented on graphs. The authors compared theoretical considerations with the case of real stator current of an asynchronous motor with a broken cage. This article can be used as a base for further studies on the diagnosis of induction motors
An E scher-like architect
Get PDFIt’s a beautiful game that enables us to create paradoxes, to reconstruct deformed images and to deform properly constructed ones. I t’s beautiful play in which imagination is the way of seeing reality and a form follows a vision, jumping by order of a randomly thrown dice
Supplementary lighting control in office room with minimized glazing area
Get PDFThe paper is dedicated to present and compare two methods of controlling supplementary lighting system in office with limited glazing area. The lighting energy demand was evaluated taking into account positioning of light sensors and room occupancy. Comparison of daylight conditions in the rooms with different orientations was carried out. The results shows the effect of occupancy scenario on lighting control strategy
Architecture „in lines”
No full textA line is an integral element accompanying architecture. It is the first line in a project idea record. A line can describe the form of a building, it can also be its main mean of expression. We perceive architecture by lines. A line as art in situ enriches the architectural space due to the perspective it plays with the viewer and the substance
“Why so serious?” – The joke as a means of expression in architecture
No full textThe paper presents the joke as a means of expression used in architecture. The author debates whether the architecture should always be serious. The paper describes and gives historical and contemporary examples of how the comical effect is achieved in architecture. The paper is also an attempt to explain and understand what the jokes in architecture are used for
Depredation in architecture (selected examples)
Get PDFThe conference, whose main theme for fourteen years has been “Defining the architectural space”, will this year attract participants’ attention with a provocative extension – “games and play of architecture”. From a wide spectrum of thematic approaches related to “games and play” with architecture, the author chose the aspect of the possible threats which may arise if irresponsible or immoral and ideologically determined people dabble in architecture
Ramy społeczno-kulturowe a semantyka adolescencji. Lektor i Dziewczynka z jaszczurką Bernharda Schlinka jako obrazy nazizmu i Holokaustu w kolejnym pokoleniu
No full textThe analyzed texts by Bernhard Schlink present male characters on the threshold of adulthood. The construction of these adolescences is set in the German reality of the post-war society of the 1950s and 1960s. The representation of the conditions of life and growing-up process of the male protagonists emphasizes the leading temporal and social categories, such as the class hierarchy of society, conservative upbringing, stable relations and traditional family roles. Moreover, the leading character constellations, which make the protagonists recall the past of the previous generation, are also significant for their biography and identity. The most important question in the analysis concerns the nature and aim of the participation of the members of the succeeding generation in the events and atrocities of the Nazi era of World War II, and the way those events influence the socio-cultural context of their adolescence and identity
Rzeki Adda i Pad jako miejsca pamięci literackiej w idylli Adda Alessandra Manzoniego
Get PDFThe article aims at analyzing the idyll Adda by Alessandro Manzoni, one of the greatest representatives of the Italian Romanticism. The Adda is one of the early, neoclassical works of Manzoni. The young author presents the monologue of the nymph Adda, the goddess of the river of the same name, who invites to her humble kingdom the poet Vincenzo Monti, born on the banks of the great Po. The rivers Adda and Po are presented in the Manzoni’s idyll as the places of the literary memory
Baletowe inspiracje Dziadkiem do orzechów E.T.A. Hoffmanna, czyli o unii tańca i literatury (na przykładzie baletu Petipy/Iwanowa)
Get PDFThe Nutcracker is a well-known short story by E.T.A. Hoffmann. In mid-19th century it was converted into a libretto and became the basis of one of the most famous ballets, still performed in theatres all over the world at Christmas time. The article attempts at showing the reader how the main elements of the work emerged. It analyzes the process of creating the musical score by Pyotr Tchaikovsky, and the strictly connected choreography by Marius Petipa and Lev Ivanov. This allows for a comprehensive, in-depth reception of the ballet, which captivates not only the youngest audience. The author of the article also argues in favour of the huge semantic potential of the non-verbal art of dance, which can bring a range of interesting contexts and interpretations out of literature
Je fabule, donc je résiste
Get PDFThis article casts a harsh light on the literary and plastic work of two Moroccan painterswriters : Mohammed Kacimi and Mahi Binebine. It will show their creative writing (poetry and fiction) and plastic is an act of resistance. This study therefore a double challenge. This is firstly to show that the story proffered on behalf of Scheherazade, in the poetic work of Kacimi is pacifist and « anti-war », secondly to see how each of novelistic characters becomes Binebine – it double the male narrator of One Thousand and One Nights
