Effects of Coarse Aggregate Morphological Characteristics on Mechanical Performance of Stone Matrix AsphaltLiu, Yufeng 26 July 2017 (has links)
This research focused on three main objectives: (1) quantify coarse aggregate morphological characteristics using an improved FTI (Fourier Transform Interferometry) image analysis system, (2) evaluate the effects of morphological characteristics of coarse aggregates of various mineral compositions on the mechanical performances of stone matrix asphalt (SMA) mixtures constituted; (3) investigate the relationship between the uncompacted void content of coarse aggregates and morphological characteristics. To achieve the first research objective, a Fourier Transform Interferometry (FTI) system was adopted to capture three-dimensional high-resolution images of aggregates. Based on these digital images, the FTI system uses the two-dimensional Fast Fourier Transform (FFT2) method to rapidly measure aggregate morphological characteristics, including sphericity, flatness ratio, elongation ratio, angularity, and surface texture. The computed shape characteristics of all aggregates were in good agreement with manual measurement results, demonstrating the accuracy and reliability of this image analysis system. For the second objective, a series of simple performance laboratory tests were performed on eight types of SMA mixtures with different morphological characteristics. Test included wheel-track loading, dynamic modulus, flow number, and beam fatigue. The wheel tracking test included asphalt pavement analyzer (APA) and Model mobile load simulator (MMLS). In the APA test, samples included eight types of SMA mixtures that consisted of aggregates of 22 fractions. In the MMLS test, six types of SMA mixture samples that consist of coarse aggregate of 15 fractions were tested. Regression analyses were then conducted between weighted mean morphological characteristics and performance parameters. The fatigue performance parameters include |E*|sin φ, where |E*| is complex modulus obtained from dynamic modulus test, the number of loading cycles to failure, and the seismic modulus difference. The rutting performance parameters include |E*|/sin φ, flow number, flow number slope, rut depth and creep slope. For the third objective, different coarse aggregate fractions from different quarries in Virginia were analyzed using the improved FTI system. Regression analyses were performed to investigate the correlation between morphological characteristics and uncompacted void content of coarse aggregates at the size ranges of 4.75-9.5mm and 9.5-12.5 mm, respectively. Aggregate morphological characteristics were found to play an important role in the mechanical performance of stone matrix asphalt mixture and the uncompacted air void content of the coarse aggregates. Both the experimental results and simulation results demonstrated that using more of equi-dimensional, less flaky and elongated coarse aggregates with angular and rougher-textured aggregates is favorable to the mechanical performances of SMA mixtures. Recommended values for each morphological characteristic are provided. / Ph. D. / Asphalt concrete pavement is used in roads around the world. Keeping this pavement in working condition requires routine maintenance, which can be costly. Therefore, a key problem in civil engineering is the design of resilient asphalt concrete that requires less maintenance. This dissertation experimentally investigates the relationship between the composition of asphalt concrete and its performance. To determine the relationship, several samples of asphalt concrete were collected. Aggregates from these samples were then scanned, and software was used to determine the properties of these aggregates. These asphalt concrete samples were then experimentally tested to determine their mechanical properties. A relationship was then established between the software-determined properties of the aggregates and the mechanical properties of the asphalt concrete samples.

A influência de características morfológicas no desempenho e apropriação de espaços urbanos : estudo de caso de Charqueadas - RSBorba, Vinícius Silveira January 2015 (has links)
Este estudo investiga a influência de diferentes características morfológicas no desempenho e na apropriação de espaços urbanos através de uma análise comparativa entre dois bairros com diferentes configurações espaciais, localizados na cidade de Charqueadas-RS: O Bairro Centro, que representa o modelo tradicional urbano, com traçado retilíneo, altos índices construtivos, diversidade de usos e edificações dispostas no alinhamento da rua; e a Vila Piratini, bairro constituído com as características das cidades jardins: traçado orgânico das ruas, baixos índices construtivos, zoneamento de usos, densa cobertura vegetal e edificações dispostas de forma orgânica em torno de cul-de-sacs limitados por amplas áreas verdes. O estudo pretende contribuir para um melhor entendimento de como diferentes configurações que constituem o espaço da cidade, afetam o uso e influenciam a satisfação e a preferência de usuários. A investigação foi operacionalizada por meio da utilização de métodos qualitativos e quantitativos em duas etapas. A coleta e análise de dados foram feitas a partir de procedimentos metodológicos da área de estudo ambientecomportamento. A primeira etapa incluiu o levantamento de dados primários e secundários e a aplicação de mapas mentais e entrevistas. A segunda etapa consistiu na realização de levantamento físico, observações comportamentais e aplicação de questionários. Os dados obtidos através de múltiplos meios permitiram estabelecer relações entre as características morfológicas, as variáveis definidoras da qualidade do espaço construído - agrupadas em uso, estrutura e aparência - e o desempenho e apropriação dos espaços urbanos. Através deste estudo, foi possível identificar potencialidades e deficiências de espaços públicos com diferentes configurações urbanas, através da avaliação de desempenho feita a partir do ponto de vista do usuário. Os resultados obtidos confirmam que os tipos de usos são afetados pelas características morfológicas dos bairros, que tornam os espaços mais, ou menos propícios para a realização de determinadas atividades. Foi constatado que o desempenho e a apropriação urbana, quando relacionados ao uso, parecem ser favorecidos pela configuração urbana tradicional, principalmente no que se refere a intensidade de interação social em praças e parques, enquanto a configuração urbana das cidades jardins parece favorecer a prática de atividades esportivas, de interação social e a realização de atividades lúdicas em frente às casas. Quanto a estrutura, características da configuração urbana tradicional, em comparação com a configuração urbana das cidades jardins, tende a favorecer a orientação, acessibilidade e permeabilidade, enquanto o traçado orgânico e a vegetação característicos do modelo de cidade jardim, são relevantes para a construção da imagem e para fortalecer a percepção de território e a imageabilidade. Quanto ä aparência, foi confirmado que o desempenho e apropriação urbana são favorecidos mais fortemente pela configuração urbana das cidades jardins, em comparação com a configuração urbana tradicional. Ainda, a aparência visual da configuração urbana das cidades jardins apresentou relevância na preferência de locais para moradia e na predileção por escolhas de locais para a realização de atividades esportivas de deslocamento e a satisfação com a aparência dos espaços públicos apresentou-se diretamente relacionada com a satisfação geral em relação ao bairro de moradia, sendo a configuração do modelo de cidade jardim avaliada mais positivamente em relação ao modelo tradicional de cidade. / This study investigates the influence of different morphological features in performance and appropriation of urban spaces through a comparative analysis between two neighborhoods with different spatial configurations, located in Charqueadas-RS: The Center District, which represents the traditional urban model, with a rectilinear layout, high construction rates, diversity of uses and buildings located in the alignment of the road; and Vila Piratini, which was built according to the characteristics of garden cities: organic layout of the streets, low construction rates, zoning uses, dense vegetation and buildings organically displayed around cul-de-sacs with large green border areas. It intends to contribute for a better understanding on the manner different urban configurations can affect use, influence user satisfaction and preferences. The investigation was implemented through the use of qualitative and quantitative methods in two stages. The collection and analysis of data were made through methodological procedures based on the environment-behavior study perspective. The first stage included the collection of primary and secondary data and application of mental maps and interviews. The second stage consisted of physical survey, behavioral observations and questionnaires. The data obtained through multiple means allowed to establish relations among the morphological characteristics, the defining variables of the quality of the built space - grouped in use, structure and appearance – and the performance and the appropriation of urban spaces. The study allowed the identification of potentialities and deficiencies of public spaces with different urban urban configurations by means of performance evaluation carried out through user's point of view. Results confirm that uses are affected by the morphological characteristics of the two neighborhoods, which provide spaces more and less adequate to perform specific activities. It was verified that performance and urban appropriation, when related to activities, seem to be favored by traditional urban configuration, regarding intensity of social interaction in squares and parks, while urban configuration of garden cities seems to favor sport activities, social interaction and playing activities in front of dwellings. Regarding structure, it was found that traditional urban configuration, when compared to garden city urban configuration, tend to favor orientation, accessibility and permeability, while the organic traces and the characteristic vegetation of garden city models can facilitate image construction and intensify user perception of territory and imageability. Regarding appearance, it was confirmed that performance and urban appropriation are positively affected by urban configuration of garden city model, when compared to traditional urban configuration. Yet, visual appearance of garden cities affected preference for place of residence e selection of places to perform sport activities and satisfaction with the appearance of public spaces was related to general satisfaction with the neighborhood of residence, where garden city configuration was more positively evaluated than the traditional urban configuration.

La morfología de los cuentos de hadas en los filmes del Studio Ghibli: El viaje de Chihiro y La tumba de las luciérnagas / The morphology of fairy tales in Studio Ghibli's films: Chihiro's Journey and The Firefly's TombAlvarado Suyo, Sofía Almendra 04 February 2021 (has links)
La presente tesis tuvo como propósito identificar las características morfológicas del cuento de hadas propuesto por Vladimir Propp (1928), El viaje de Chihiro (2001) de Hayao Miyazaki y La tumba de las luciérnagas de Isao Takahata (1988), ambas pertenecientes al Studio Ghibli, siendo las más representativas para los autores y del estudio de animación. Tuvo un enfoque cualitativo-descriptivo. Se analizaron, bajo las categorías, situaciones y personajes. Los resultados muestran que ambos filmes comparten las mismas categorías expuestas en la teoría. Pero, existen diferencias en cantidad y secuencia en la categoría Sucesiones y en categoría Personajes, el antagonista y el héroe se encuentran en constante evidencia a lo largo de todo el filme. Concluyendo, que los dos productos audiovisuales se basan en la morfología de los cuentos de hadas propuesta por Vladimir Propp, manteniendo una estructura similar y dinámica; incluso cuando la visión de los autores pueda ser opuesta. Resaltando que el protagonista resuelve sus propios conflictos u obstáculos sin la necesidad que un tercero intervenga directamente. Se recomienda investigar la morfología, elementos o características de otros filmes sobre cuentos de hadas, desarrollados dentro del Estudio Ghibli, que no han tenido similar reconocimiento a nivel mundial. / The present thesis had the purpose of identifying the morphological characteristics of the fairy tale proposed by Vladimir Propp (1928), The Journey of Chihiro (2001) by Hayao Miyazaki and The Tomb of the Fireflies by Isao Takahata (1988), both belonging to the Studio Ghibli, being the most representative for the authors and the animation studio. It had a qualitative-descriptive approach. They were analyzed, under the categories, situations and characters. The results show that both films share the same categories exposed in the theory. But there are differences in quantity and sequence in the category Successions and in the category Characters, the antagonist and the hero are in constant evidence throughout the film. In conclusion, the two audiovisual products are based on the morphology of fairy tales proposed by Vladimir Propp, maintaining a similar and dynamic structure; even though the vision of the authors may be opposite. It should be noted that the protagonist resolves his own conflicts or obstacles without the need for a third party to intervene directly. It is recommended to investigate the morphology, elements, or characteristics of other fairy tale films, developed within Studio Ghibli, which have not had similar recognition worldwide. / Tesis

<p>Основни проблем истраживања је утврђивање ефикасности проприоцептивног тренинга у развоју антрополошких показатеља фудбалера и ученика средњих школа. Поставља се питање да ли ће вежбање применом експерименталног модела тренинга допринети да се ниво морфолошких карактеристика, телесне композиције, базичних и специфичних моторичких способности подигне на виши ниво.<br />Циљеви истраживања су: да се утврди иницијално стање антрополошких показатеља фудбалера и ученика неспортиста; да се утврде разлике антрополошких показатеља фудбалера и ученика неспортиста на иницијалном стадијуму; да се утврде трансформације антрополошких показатеља експерименталне и контролне групе фудбалера и ученика неспортиста од иницијалног до финалног стадијума; да се утврде разлике у нивоу антрополошких показатеља експерименталне и контролне групе фудбалера и ученика неспортиста на финалном стадијуму.<br />Истраживање је спроведено на узорку од 250 испитаника дефинисаном као популација фудбалера и ученика средње Пољопривредне школе из Бачке Тополе, мушког пола, узраста 15 и 16 година (1997. и 1998. годиште). Експерименталне групе чине 125 испитаника: Е1 - 62 млада фудбалера; Е2 - 63 ученика који се не баве активно спортом. Контролне групе чине 125 испитаника: К1 - 66 младих фудбалера; К2 - 59 ученика који се не баве активно спортом. Узорак варијабли чине: морфолошке карактеристике, телесна композиција, базичне и специфичне моторичке способности.<br />Применом унивариатне и мултивариатне анализе варијансе, као и коваријансе, установљено је да је проприоцептивни тренинг у трајању од десет недеља изазвао појаву значајне промене базичних и специфичних моторичких способности. Статистички значајне разлике антрополошких показатеља фудбалера и ученика неспортиста постојале су пре примене проприоцептивног тренинга. Услед примене проприоцептивног тренинга дошло је до појаве статистички значајне разлике базичних (.000) и специфичних моторичких способности (.023) код експерименталне групе фудбалера, као и базичних (.000) и специфичних (.004) моторичких способности код експерименталне групе ученика неспортиста. Код контролне групе ученика неспортиста дошло је до појаве значајне разлике само код специфичних моторичких способности (.022). Постоји статистички значајна разлика антрополошких показатеља експерименталних и контролних група фудбалера и ученика неспортиста на финалном стадијуму. Иако су и контролне групе постигле одређени напредак (претпоставља се услед раста и развоја организма у том периоду живота, као и утицаја неких других фактора који нису обухваћени овим радом) закључак овог истраживања је да проприоцептивни тренинг пружа значајно већи напредак од уобичајеног плана и програма рада на часовима физичког вежбања и да доприноси значајном напредку код испитаника који се налазе у тренежном процесу.</p> / <p>Osnovni problem istraživanja je utvrđivanje efikasnosti proprioceptivnog treninga u razvoju antropoloških pokazatelja fudbalera i učenika srednjih škola.

Uzorak varijabli čine: morfološke karakteristike, telesna kompozicija, bazične i specifične motoričke sposobnosti.<br />Primenom univariatne i multivariatne analize varijanse, kao i kovarijanse, ustanovljeno je da je proprioceptivni trening u trajanju od deset nedelja izazvao pojavu značajne promene bazičnih i specifičnih motoričkih sposobnosti. Statistički značajne razlike antropoloških pokazatelja fudbalera i učenika nesportista postojale su pre primene proprioceptivnog treninga. Usled primene proprioceptivnog treninga došlo je do pojave statistički značajne razlike bazičnih (.000) i specifičnih motoričkih sposobnosti (.023) kod eksperimentalne grupe fudbalera, kao i bazičnih (.000) i specifičnih (.004) motoričkih sposobnosti kod eksperimentalne grupe učenika nesportista. Kod kontrolne grupe učenika nesportista došlo je do pojave značajne razlike samo kod specifičnih motoričkih sposobnosti (.022). Postoji statistički značajna razlika antropoloških pokazatelja eksperimentalnih i kontrolnih grupa fudbalera i učenika nesportista na finalnom stadijumu. Iako su i kontrolne grupe postigle određeni napredak (pretpostavlja se usled rasta i razvoja organizma u tom periodu života, kao i uticaja nekih drugih faktora koji nisu obuhvaćeni ovim radom) zaključak ovog istraživanja je da proprioceptivni trening pruža značajno veći napredak od uobičajenog plana i programa rada na časovima fizičkog vežbanja i da doprinosi značajnom napredku kod ispitanika koji se nalaze u trenežnom procesu.</p> / <p>The basic problem of the research is establishing the efficiensy of the proprioceptive training in the development of anthropological indicators of football players and secondary school pupiles. The question is whether exercises with the application of an experimental training model will contribute that the existing level of the morphological characteristics, body composition, basic and specific motor abilities is raised to a higher level.<br />The research goals are: to establish the initial state of anthropological indicators of the football players and students nonathletes; to establish the differences of the anthropological indicators football players and students nonathletes on the initial stadium, to establish the transformation of the anthropological indicators of the experimental and the control group of the football players and students nonathletes from the initial to the final stadium; to establish the differences on the level of the anthropological indicators of the experimental and the control group of football players and students nonathletes in the final stadium.<br />The research has been carried out on the sample of 250 male exeminees defined as a population of football players and students of the secondary Agricultural school from Bačka Topola, at the age of 15 and 16 years (age groups 1997 and 1998). The Experimental groups consists of 125 exeminees: E1 - 62 young football players , E2 - 63 students who do not go in for sport actively. The Control groups consist of 125 examinees: C1 - 66 young football players, C2 - 59 students who do not go in for sports actively. The variable sample consists of: morphological characteristics, body composition, basic and specific motor abilities.<br />With the application univariant and multivariant analysis of variance, as well as covariance, it has been established that the proprioceptive training lasting ten weeks has caused significant changes of basic and specific motor abilities. Statistically significant differences of the anthropological indicators of football players and students non - athletes existed prior to the application of the proprioceptive training. The application of the proprioceptive training resulted statistically significant difference of the basic (.000) and the specific motor abilities (.023) with the experimental group of young football players, as well as the basic (.000) and specific (.004) motor abilities with the experimental group of the students nonathletes. With the control group of students nonathletes a significant difference oecured only with specific motor abilities (.022). There is a statistically significant difference of the anthropological indicators of the experimental and control group of football players and the students nonathletes in the final stadium. Although the control group has achieved certain progress, due to, the growth and the development of the organism in that life period. Proprioceptive training offers significantly greater progress than the customary plan and programme of the physical exercise classes and that it contributes to the significant progress with the examinees who are in the training process.</p>
