Curved Track Analysis of FSO Link for Ground-to-Train Communications
No full textIn this work, a free space optical (FSO) link for the ground-to-train (G2T-FSO) communications is proposed. Analytical analysis is carried out for the curved rail tracks. We show that the transmitter divergence angle, the transmit power and the size of the concentration lens need to increase for the curved section of the rail track compared to the straight track. We derive the analytical expression for the received power level based on the link geometry for the case of the curved track In the worst case scenario when the curvature radius is 120 m, the transmit power at the optical base station (BS) needs to increase by over 2 dB when the concentration lens radius is increased by 5 times. Analyses also show that the received power along the track increases with the curvature radius for the same transmit power and receiver optics illustrating the effect due to link geometry. Additionally, the signal-to-noise ratio (SNR) and the bit error rate (BER) performance of the system for the curved track with different curvature radii is analysed at data rates of 10 Mbps and 100 Mbps for an additive white Gaussian noise (AWGN) channel showing a good agreement between the theoretical and the simulated BER. Finally, effect of scintillations on the G2T-FSO link performance is discussed
Laser beam shaping
No full textABSTRACT: In this thesis, the author has tried to research about several methods and techniques to transform a Gaussian input beam of a optical system into a flat-top (uniform) output beam. In practical part, approaches of geometrical and diffusers techniques are used. The model of diffuser will be experimentally confirmed during the experiment. In the final part, results of this experiment and simulation are discussed.RESUMEN: En esta tesis, el autor ha tratado de investigar varios métodos y técnicas para transformar un haz de rayos en la entrada del sistema óptico con distribución Gaussiana en un haz de rayos en salida con una distribución uniforme. En la parte práctica se usan enfoques de las técnicas geométricas y de difusores. El modelo del difusor será confirmado con un experimento. Al final los resultados del experimento y la simulación serán discutidosIngeniería de Telecomunicació
Influence of different interpolation techniques on the determination of the critical conditions for the onset of dynamic recrystallisation
No full textAccurate modeling of dynamic recrystallization (DRX) is highly important for forming processes like hot rolling and forging. To correctly predict the overall level of dynamic recrystallization reached, it is vital to determine and model the critical conditions that mark the start of DRX. For the determination of the critical conditions, a criterion has been proposed by Poliak and Jonas. It states that the onset of DRX can be detected from an inflection point in the work hardening rate as a function of flow stress. The work hardening rate is the derivative of the flow stress with respect to strain. Flow curves are in general measured at a certain sampling rate, yielding tabular stress-strain data, which are per se not continuously differentiable. In addition, inevitable jitter occurs in measured flow curves. Hence, flow curves need to be interpolated and smoothed before the work hardening rate and further derivatives necessary for evaluating the criterion by Poliak and Jonas can be computed. In this paper, the polynomial interpolation originally proposed by Poliak and Jonas is compared to a new approach based on radial basis functions using a thin plate spline kernel, which combines surface interpolation of various flow curves and smoothing in a single step. It is shown for different steel grades that the interpolation method used has a crucial influence on the resulting critical conditions for DRX, and that a simultaneous evaluation by surface interpolation might yield consistent critical conditions over a range of testing temperatures. © (2013) Trans Tech Publications, Switzerland
Anatomical study of fiber connections of the temporal pole in the cat and monkey
No full textThe understanding of the functions of a certain portion of the cortex ultimately is dependent on a knowledge of the connections or interrelationships of that particular cortex. Consequently, the visual cortex and the auditory area are better understood because of the works of Poliak (1932), Talbot (1942), Talbot, Woolsey and Thompson (1946), and of Walker (1937a,1937b), of Ades and Felder (1942, 1945), Ades (1943), Woolsey and Walzl (1942), Walzl and Woolsey (1943), Tunturi (1944, 1945), Rose (1949), and Rose and Woolsey (1949)
Les usages sociaux de la lecture
No full textSoziale Lesegebräuche.
Nicht etwa eine durchgehende, in bezug auf ein ideales Leseverhalten des perfekten Lesers abstufbare Skala von Lesepraktiken bringt die Untersuchung ans Licht, sondern eine in drei Kategorien gleichrangig zu klassifizierende Palette dieser Praktiken : Lektüren zur Entspannung (lesen « um zu träumen ») didaktische Lektüren (lesen « uni zu lernen ») und Heilslektüren (lesen, « um sich zu vervollkommnen »), keine unter ihnen auf eine rein ästhetische Lektüre (« lesen um des Lesens willen ») reduzierbar. Bei Betrachtung der Absichten, Motive, erklärten Gründe, sowie des tatsächlichen Verhaltens der befragten Personen sollten die Interessen ausgemacht werden, die über das ästhetische Vergnügen hinaus, Veranlassung zum Lesen all denen geben, die nicht - wie befundlich festgestellt - ausschließlich dem « reinen Vergnügen » zugerechnet werden können, sowie die praktischen Folgen dieses Lesens und die von ihm erhofften Wirkungen. Solche « Leseinteressen » sind prinzipiell in ihrer Geschichte, ihrer Position im sozialen Raum, in den kulturellen und bewahr-ten schulischen Hilfsquellen, in den erlangten beruflichen Positionen und in den sozial etablierten sexuellen Identitäten begründet. Die Offenlegung des sozialen Gebrauchs der Lektüre und der sie bewegenden Interessen erlaubt so bessere Einsichten in die soziale Verteilung des Leseverhaltens.The social uses of reading.
Far from revealing a gamut of reading practices that could be ranked with respect to the ideal reading performed by an accomplished reader, the study shows a series of practices that can be broken down into three categories : pleasure reading (« reading for the sake of escape »), didactic reading (« reading for the sake of learning ») and salutary reading (« reading for the sake of self-perfection »), none of which is the same as esthetic reading (« reading for the sake of reading »). By looking at the informants' intentions, motives, stated reasons, but also at their actual practices, the author attempts to bring out the interests which, apart from esthetic pleasure, incite all readers who - in the absence of the requisite conditions - remain inaccessible to «pure pleasure », the uses to which they put their readings, the effects they hope for. These « interests in reading » stem from the informants' background and their position in the social space, from their cultural and educational resources, from their professional occupation, from their socially constituted sexual identity. The uncovering of the social uses of reading and their underlying interests contributes to a fuller explanation of the social distribution of reading practices.Les usages sociaux de la lecture.
Loin de révéler un nuancier de pratiques de lecture qu'il serait possible d'ordonner par rapport à la lecture idéale du lecteur accompli, l'enquête met en évidence un répertoire de pratiques qu'il est possible de classer en trois catégories : lectures de divertissement (lire « pour s'évader »), lectures didactiques (« lire pour apprendre ») et lectures de salut (« lire pour se parfaire »), toutes irréductibles à la lecture esthète (« lire pour lire»). À travers l'étude des intentions, des motifs, des raisons déclarés, mais aussi des pratiques des enquêtes, il s'agissait de mettre au jour les intérêts qui, en dehors du plaisir esthétique, portent à lire tous ceux qui - faute des conditions requises - restent inaccessibles au « plaisir pur », les usages qu'ils font de leurs lectures, les effets qu'ils en attendent. Ces « intérêts à la lecture » trouvent leur principe dans leur histoire et leur position dans l'espace social, dans les ressources culturelles et scolaires détenues, dans les positions professionnelles occupées, dans les identités sexuelles socialement constituées. La mise au jour des usages sociaux de la lecture et des intérêts qui les sous-tendent permet alors de mieux rendre compte de la distribution sociale des pratiques de lecture.Los usos sociales de la lectura.
En esta investigación no se prétende desplegar un muestrario de prácticas de lectura, ordenándolas para compararlas luego con la lectura ideal de un lector consumado. Si se presenta un repertorio de prácticas que pueden clasificarse en tres categorías : lecturas de entretenimiento (« leer para distraerse »), lecturas didácticas (« leer para aprender ») y lecturas de salvación (« leer para superarse »), todas elles irreductibles a la lectura del esteta (« leer por la lectura en si »). A través del estudio de las intenciones, las razones y los motivos expuestos por las personas interrogadas, como también de sus prácticas, se trata de descubrir cuáles son los intereses que, independientemente del placer estético, conducen a leer a quienes -por falta de condiciones necesarias- permanecen sin tener acceso al « placer puro », que uso hacen de sus lecturas y que resultados esperan. La historia personal de los lectores, su posición en el espacio social, los recursos culturales y de escolarización, así como la posición profesional que ocupan y la identidad sexual socialmente constituida, explican tales « intereses por la lectura ». Poner de manifiesto los usos sociales de la lectura y los intereses que les sirven de sustento permite entonces reflejar mejor la distribución social de las prácticas de lectura.Mauger Gérard, Poliak Claude.
