Estudi de modelat de canal a ISAC per a 6G
No full text[ES] La tecnología 6G representa la próxima generación de redes móviles, prometiendo velocidades ultrarrápidas, baja latencia y conectividad masiva. Para lograrlo, 6G promete incorporar tecnologías como la inteligencia artificial (IA) o la detección (sensado) y comunicaciones integradas (ISAC), en la cual se centra el presente proyecto. ISAC permite a las redes 6G no solo transmitir datos, sino también detectar y rastrear objetos, mejorando aplicaciones como vehículos autónomos y reconstrucción del entorno.
El desarrollo de nuevos modelos de canal para ISAC es vital para su desempeño, ya que los modelos tradicionales no son adecuados al centrarse tan solo en las comunicaciones, mientras que en ISAC deben presentar como el entorno y los objetos interactúan con el canal, incluyendo nuevas características como la sección recta radar (RCS), no presentes anteriormente en los modelos de comunicaciones convencionales.
Estos nuevos modelos de canal para ISAC presentan varias opciones dependiendo del caso de uso. Estos van a ser analizados en este trabajo, donde se estudiarán modelos estocásticos, deterministas o híbridos (una mezcla de los dos anteriores). A su vez, se estudiará como modelar los objetos detectados: como simples o múltiples puntos de dispersión (scattering), como distribuciones estadísticas, como funciones y/o tablas, etc.[EN] 6G technology represents the next generation of mobile networks, promising ultra-fast data speeds, low latency and massive connectivity. To achieve this, 6G promises to incorporate technologies such as artificial intelligence (AI) or integrated sensing and communications (ISAC), which is the focus of this project. ISAC enables 6G networks not only to transmit data, but also to detect and track objects, enhancing applications such as autonomous vehicles and environmental reconstruction.
The development of new channel models for ISAC is vital for its performance, since traditional models are not adequate as they focus only on communications, while in ISAC they must present how the environment and objects interact with the channel, including new features such as radar cross section (RCS), not previously present in conventional communications models.
These new channel models for ISAC present several options depending on the use case. These will be analyzed in this work, where stochastic, deterministic or hybrid models (a mixture of the two previous ones) will be studied. In addition, it will be studied how to model the detected objects: as single or multiple scattering points, as statistical distributions, as functions and/or tables, etc.Micó Rosa, S. (2024).

A poética do olhar: velamentos e desvelamentos das transvisões de Guimarães Rosa
No full textGuimarães Rosa's work offers opportunities to explore the potential of the gaze in its most varied nuances. Through short stories, novels and his masterpiece, the novel Grande sertão: veredas, the author from Minas Gerais presents a multiplicity of characters that make up a very rich and complex gallery of human types who seek to understand the world and themselves through a particular optics that is, at the same time, universal. They are children, old and crazy, most of them from the country side of the so-called civilizing process, but with wisdom and insight that border on the sublime. Rosa's characters present a kind of original look, almost naive, but capable of revealing what is hidden behind the apparent reality. It is these transvisions of the gaze, with their veils and unveilings, that this book investigates, based on the encounter with emblematic works by Guimarães Rosa, namely: Sagarana, Corpo de baile, Grande sertão: veredas and Primeiras estórias.A obra de Guimarães Rosa oferece oportunidades para se explorar as potencialidades do olhar em suas mais variadas nuances. Através dos contos, novelas e da sua obra-prima, o romance Grande sertão: veredas, o autor mineiro apresenta uma multiplicidade de personagens que compõem uma riquíssima e complexa galeria de tipos humanos que procuram entender o mundo e a si mesmos por meio de uma ótica particular que é, ao mesmo tempo, universal. São crianças, velhos e loucos, em sua grande maioria sertanejos à margem do processo dito civilizatório, mas com sabedoria e perspicácia que beiram o sublime. Os personagens rosianos apresentam um tipo de olhar original, quase ingênuo, mas capaz de desvelar o que se esconde por trás da realidade aparente. São essas transvisões do olhar, com seus velamentos e desvelamentos, que este livro investiga, a partir do encontro com obras emblemáticas de Guimarães Rosa, a saber: Sagarana, Corpo de baile, Grande sertão: veredas e Primeiras estórias
A rosa fenecida: crônicas
No full text“A Rosa Fenecida: Crônicas” is a book by the author Chico Viana, who holds a PhD in Literature from the University of Rio de Janeiro. The book brings together chronicles published in the newspaper “O Norte”, in which the author humorously addresses everyday issues. Some of the chronicles in this book address topics such as the praise of routine, a new letter to Pero Vaz de Caminha, the setbacks resulting from replacing an old mattress, and a plot of figures of speech against grammar. The author is aware that the chronicler is, at most, a pool diver or a wall climber.“A Rosa Fenecida: Crônicas” é um livro do autor Chico Viana, que é doutor em Literatura
pela Universidade do Rio de Janeiro. O livro reúne crônicas publicadas no jornal “O Norte”,
onde o autor trata com humor assuntos do cotidiano.
Algumas das crônicas presentes neste livro abordam temas como o elogio da rotina, uma
nova carta a Pero Vaz de Caminha, os contratempos decorrentes da troca de um colchão
velho, e um complô das figuras de linguagem contra a gramática. O autor tem a consciência
de que o cronista é, no máximo, um escafandrista de piscinas, ou um alpinista de muros
An evaluation of interlayer stress absorbing composite (ISAC) reflective crack relief system
No full textIHR-R07Reflective cracking of bituminous concrete overlays has long been a problem in pavement rehabilitation. Various types of interlayer systems and fabrics have been used to eliminate or slow the development of reflective cracks. These methods and products have had mixed results. In 1993, the University of Illinois completed research directed by the Illinois Department of Transportation on a prototype Interlayer Stress Absorbing Composite (ISAC). A prototype test section was placed on IL 38 near Rochelle, IL in 1993. Other ISAC test sections were placed on five asphalt concrete overlay (ACOL) projects between 1997 and 2000. Some of these ACOL sections contain other reflective crack control methods, such as Sand Anti-Fracture (SAF) layer, strip, and area-wide reflective crack control fabric. ISAC consists of a three-layer system. The top layer is a high strength woven geotextile to resist stresses caused by underlying pavement movements. This layer has the ability to, due to its weaving, expand like a chain link fence. This movement dissipates the stress caused by the movement of the underlying pavement. Typically, this geotextile has a tensile strength greater than 4,000 lb. /in. (700 N/mm) at 5% strain (ASTM D 4595). High strength is needed to ensure that, when the geotextile is expanded to its full extent, the geotextile strength is greater than the strength of the bituminous concrete overlay. The bottom layer is a low strength, nonwoven, geotextile (meeting AASHTO M-288-92). The middle layer is a modified rubberized asphalt layer to absorb the strain energy and bond the two geotextiles together. The system bridges across the joint or crack and dissipates stresses resulting from opening or closing movements. ISAC is bonded to the existing pavement using a tack coat and then the overlay is placed. The formation of reflective cracks and the subsequent deterioration of these cracks were delayed at ISAC treated joints and cracks. This statement was true for all five test sites. This delay ranged from over one year to close to three years when compared to the untreated and other crack control methods. Of special note, the ISAC areas consistently outperformed the System B products, PavePrep and Roadtac. When compared with SAF, the ISAC delayed reflective cracks by about two years. The two sections performed the same after the cracks were routed and sealed. The cost analysis indicated that the higher the total cost of the asphalt concrete the higher the number of cracks and joints that could be treated with ISAC. The present cost of the ISAC strips, 14 per foot, limits the conditions under which it would be cost effective to use ISAC. If asphalt costs are high or the cost of ISAC were to decline, there would be more projects that could benefit from using ISAC. Described herein are details of the various experimental field installations and a discussion of performance and results. Recommendations for the use of ISAC are included. /Abstract from report summary page

O “criticismo de gêneros” na poética de Guimarães Rosa
No full textResumo: Autor de contos, novelas e do romance Grande sertão: veredas, Guimarães Rosa é reconhecido pela engenhosidade de suas narrativas e por um estilo que seria expressão de uma personalidade artística ímpar na literatura brasileira. O poder que suas narrativas têm de surpreender os leitores em suas expectativas convencionais se manifesta de modo singular no último livro do escritor. Neste artigo, pretendemos apresentar e analisar o modo como Tutaméia: terceiras estórias está sistematicamente voltado a desautomatizar o leitor das convenções na apreensão da verossimilhança e como suas estórias e prefácios encenam aquilo que, segundo Bakhtin, seria a característica do romanesco enquanto gênero: o “criticismo”.Palavras-chave: Guimarães Rosa; Tutaméia; Bakhtin; romanesco; teoria dos gêneros.Abstract: Author of a range of literary genres, such as short stories, novels and the well-known novel Grande Sertão: Veredas, Guimarães Rosa is recognized for the ingenuity of his narratives. Moreover, the author is acknowledged for a style which is the expression of a unique artistic personality in Brazilian literature. The power of his narratives to astonish readers’ conventional expectations is manifested in his last book, Tutameia: Terceiras Estórias, in quite a singular way. In this article we intend to present and analyze the way in which Tutameia: Terceiras Estórias is systematically aimed at de-automating the readers’ conventions regarding their apprehension of verisimilitude. In addition, it is intended to show how Guimarães Rosa stories and forewords stage what Bakhtin would define as the characteristic of the Romanesque as a genre: the “criticism”.Keywords: Guimarães Rosa; Tutameia; Bakhtin; romanesque; genre theory

Dept. of Civil EngineeringUnited States. Federal Highway AdministrationNTL-HIGHWAY/ROAD TRANSPORTATION-MaterialsUS Transportation CollectionTo approach the reflection cracking problem in AC overlays systematically the properties of the materials intended to be used in an ISAC system were first identified. Various thermal/structural models and laboratory equipment were used for this purpose. A number of woven and nonwoven geotextiles were selected and tested for their engineering properties such as tensile strength, initial modulus, modulus at failure, and percent shrinkage. Several samples of rubber asphalt were prepared by blending different ratios of crumb rubber with various types and ratios of asphalt cements at 400 F. These rubber asphalts were tested at different temperatures and the effects of temperature and rate of deformation on their stiffness were evaluated.An interlayer stress absorbing composite, ISAC layer was fabricated in the laboratory using the materials considered appropriate. Testing equipment was developed to evaluate the interfacial shear strength and laboratory testing was performed to determine the shear strength of the fabricated ISAC layer under an AC overlay. The ISAC layer was evaluated for its effectiveness against reflection cracking. A laboratory pavement section with an AC overlay over a jointed PCC slab was constructed and placed in an environmental chamber. A mechanical device was used to simulate thermal strain in the slab and the joint was opened and ciosed at an extremely slow rate. The testing was conducted at 30F and deterioration in the overlay was monitored using a sensitive LVDT device.The results from the laboratory evaluation testing program indicated that the ISAC layer was highly effective in preventing reflection cracking in a 2.5 in. AC overlay. When compared to a control test section and a section using a commercially available reflection cracking control material the ISAC layer provided for superior performance. A field pavement test section utilizing the ISAC layer was constructed in the Summer 1994 and field evacuation is ongoing
O "homo viator" na Divina Commedia e no Grande Sertão: veredas
No full textTese (doutorado) - Universidade Federal de Santa Catarina, Centro de Comunicação e Expressão. Programa de Pós-Graduação em LiteraturaEsta tese busca problematizar um estudo comparado entre a Divina commedia e o Grande sertão: veredas a partir da noção de "Homo viator". Para tanto, nossa análise se concentrou sobre a percepção do aprimoramento do viajante que é também o protagonista nas duas obras Este viajante ficcional é concebido segundo um feixe de relações que Dante-autor e Guimarães Rosa realizam ao compor suas obras, de maneira que nos primeiro e segundo capítulos nos detivemos em alguns destes elementos, a saber: a presença da noção de êxodo bíblico bem como do viajante náutico greco-latino na caracterização deste viajante, o recurso ao narrador-protagonista e a composição das obras como literatura de viagem. Para analisar estes elementos nos utilizamos dos postulados da literatura comparada, da teoria dos arquétipos e da metafísica platônica. Por fim, no terceiro capítulo, realizamos um confronto entre dois episódios das referidas obras: a viagem de Ulisses presente no canto XXVI do Inferno e a viagem ao Liso do Sussuarão presente no Grande sertão: veredas. Este estudo tem por finalidade apresentar o "Homo viator" como metáfora da incansável busca humana da verdade.This dissertation performs a comparative study between the Divina Commedia and Grande Sertão: Veredas, having as a starting-point the notion of "Homo viator". Our analysis focuses on the path towards improvement undertaken by the "traveler", who is also the protagonist in both works. This fictional traveler is conceived of as a nexus of relationships that Dante-the-author and Guimarães Rosa construct in the making of each of their works, and it is to some of these relationships that we will pay attention in the first and second chapters, namely: the notion of the biblical exodus; the figure of the Roman-Greek nautical traveler in the characterization of the "homo viator"; the narratorprotagonist as a narrative device; and the caracterization of the works as travel literature. In order to perform an analysis of such elements, we draw our theoretical premises from the field of comparative literature, the theory of archetypes, and Platonic metaphysics. Lastly, in the third chapter, we compare and contrast two episodes from the referred works: the journey undertook by Ulysses in Canto XXVI of the Inferno, and the crossing of the "Liso do Sussuarão" in Grande Sertão: Veredas. The current work aims to present the "Homo viator"as a metaphor for the indefatigable human quest for truth

Martínez de la Rosa ante el mito de Edipo: teoría crítica y creación poética
No full textGrado en lengua y Literatura EspañolasNos proponemos contextualizar el hecho poético de la teoría dramática que Martínez de la Rosa
aporta en las notas a su Poética (que vemos en el canto V De la tragedia y de la comedia). Regidos por su
afán teórico-crítico, conseguimos a nuestro parecer, una antología donde destacamos los puntos más
importantes de esta teoría, como son la fábula, el estilo, los personaje, entre otros. Ejemplificamos estos
tanto con el Edipo del autor, como el Edipo rey modélico de Sófocles.
Del mismo modo y continuando con el recorrido del autor a través de los diversos traductores y
autores, de distintas nacionalidades, que recrearon el modelo adaptándolo al teatro moderno.
Consideramos crear una antología de la Advertencia a su obra Edipo para mostrar la tradición de este, las
deficiencias de sus adaptaciones posteriores y las razones que llevan a Martínez de la Rosa a crear esta
obra.
Finalmente, guiados por las lecturas de los textos, decidimos crear un análisis comparativo del
modelo de Sófocles y de Martínez de la Rosa. En este análisis presentamos las similitudes entre los
personajes y las escenas, tanto para comprobar las soluciones que el autor ofrece para su Edipo
“perfecto”, como para mostrar una adaptación, que consideramos sin errores, del Edipo en el siglo XIX.We intend to put into context the poetic fact of dramatic theory provided by Martínez de la Rosa
in the notes to his poetics (which we see in canto V of tragedy and of comedy). Guided by its theoreticalcritic
eagerness, from our point of view, we got an anthology where we highlight the most important
points of this theory, such as the fable, the style, the characters and more. We exemplify these both the
Oedipus of the author, as Oedipus the King model by Sophocles.
In the same way and continuing with the author’s journey by the various translators and authors
from different countries, that recreated this work adapted to the modern theatre. We consider making an
anthology of the Warning to its own work Oedipus, to show the tradition of this, the deficiency of it
following adaptations, besides the reasons that lead Martínez de la Rosa to create this work.
Finally, guided by them readings of their texts, we decided to create a comparative analysis of
the model of Sophocles and of Martinez de la Rosa. In this analysis, we show the similarities of the
characters and the scenes, both for check them solutions that the author gives for his “perfect” Oedipus, as
to show an adaptation, consider without errors, of the Oedipus in the 19th century
