Thirteen Brasilian Sport Horses horses were used, 12 females and 1 castrated male with 9.0?2.8 years old mean age and 472.5?34.2 Kg mean weight, from the Army Cavalry School (EsEqEx). Linear, angular and perimeter measurements were performed with horses at forced statio. The animals were filmed at a standardized environment on the treadmill with black background and spotlights lighting. High-speed treadmill (Sahinco?) and sand track covered with flat and smooth floor were used. The images were obtained and processed by Simi Reality Motion Systems? and filmed by PiA640 Basler camera. The experiment was carried out in a completely randomized design with two treatments (horses on a high speed treadmill and mounted horses on a sand track) in paired data and 13 replications (animals). The results were submitted to variance analysis and means were compared by paired t test (P<0.05). At the day of filming, the animal performed a war up for 10 minutes at walking, trotting and galloping speeds. On the track, horses were mounted by three experienced riding instructors. Horses were classified as medium shaped and hypermetric, being the mean values for IC and IDT 0.87 and 0.11, respectively. In kinematics analysis, the following variables studied were stride length, speed pace, support time, sleep time and members foot prints on the left and right sides. In the standing-pace course just suspension time and right side foot prints presented difference (p<0.05) with the highest mean values on treadmill of 0.39s and -0.22cm (retro foot prints). In the meeting step on the treadmill analysis differences were observed (p<0.05) in stride length, support time, sleep time and members foot prints on left and right sides with the highest mean values from treadmill analysis when comparing to the sand track. In the elongated pace course, treadmill analysis presented the highest mean values for stride length and pace speed 2.1m and 1.98m/s while sand track analysis presented the highest values for support time and members foot prints on the left and right sides. In upward transitions, the same variables were significative (p<0.05) for treadmill analysis, speed pace, sleep time and members foot prints on the left and right sides, however, on two transitions, support time was higher (p<0.05) for sand track analysis. In the downward transition from gallop to trot lower (p<0.05) support time and higher suspension time were observed, being 0.21s and 0.38s, respectively. Stride length was similar (p<0.05) on horses evaluated on a treadmill and sand track, however, speed of transition was higher on treadmill being 4.03m/s in regarding to sand track 3.2m/s. In conclusion, regarding the morphometry, horses were framed on the saddle pattern for medium shape and hypermetric and; regarding kinematics, suspension time was the only variable presenting higher values for treadmill in all transitions, while stride length and speed pace presented the highest mean values for treadmill apart from for station-pace and pace-trot transitions, suggesting it may be related to influences undefined on this study. / Objetivou-se analisar as caracter?sticas morfom?tricas dos equinos e a an?lise cinem?tica dos andamentos passo, trote e galope, assim como as transi??es ascendentes e descendentes desses andamentos em esteira de alta velocidade com os animais sem cavaleiro e em pista de areia montados. Foram utilizados 13 equinos da ra?a Brasileiro de Hipismo, sendo 12 f?meas e um macho castrado, com m?dia idade de 9,0 ? 2,8 anos e peso m?dio de 472,5 ? 34,2Kg provenientes da Escola de Equita??o do Ex?rcito (EsEqEx). As medidas lineares, angulares e de per?metro foram mensuradas com os equinos em esta??o for?ada. Os animais foram filmados em ambiente padronizado na esteira e na pista, com fundo preto e ilumina??o com holofotes. Foi utilizada esteira de alta velocidade (Sahinco?) e pista de areia coberta de piso plano e regular. As imagens foram obtidas e processadas no aplicativo Simi Reality Motion Systems? e filmada com c?mera Basler piA640. O ensaio foi conduzido em delineamento inteiramente casualizado com dois tratamentos (equinos em esteira de alta velocidade e equinos montados em pista de areia), em esquema de dados pareados, 13 repeti??es (animais) e os resultados submetidos ? an?lise de vari?ncia e as m?dias comparadas pelo teste t pareado (P<0,05). No dia das filmagens, os animais realizaram aquecimento com tempo de 10 minutos, ao passo, trote e galope. Na pista os equinos foram montados por tr?s experientes instrutores de equita??o. Os equinos foram classificados em mediol?neos e hiperm?tricos, sendo as m?dias 0,87 e 0,11 para IC e IDT.Na an?lise cinem?tica, as vari?veis estudas foram comprimento da passada, velocidade da passada, tempo de apoio, tempo de suspens?o e pegadas dos membros em lateral esquerdo e direito. No andamento esta??o-passo s? houve diferen?a (p<0,05) para o tempo de suspens?o e pegada lateral direito com os maiores valores m?dios para an?lise na esteira, 0,39s e -0,22cm (retropegada). No passo reunido houve diferen?a (p<0,05) para comprimento da passada, tempo de apoio, tempo de suspens?o e para as pegadas dos membros em lateral esquerdo e direito com os maiores valores m?dios para a an?lise na esteira em rela??o a pista de areia. No andamento passo alongado a an?lise na esteira apresentou os maiores valores m?dios para comprimento da passada e velocidade da passada, 2,1m e 1,98m/s j? a an?lise na pista de areia apresentou maiores valores de tempo de apoio e para as pegadas em lateral esquerdo e direito. Nas transi??es ascendentes, apresentaram valores significativos (p<0,05) para an?lise na esteira, velocidade da passada, tempo de suspens?o e pegadas, por?m nas duas transi??es o tempo de apoio foi maior (p<0,05) na an?lise na pista de areia. Na transi??o descendente do andamento galope para o trote foi observado menor (p<0,05) tempo de apoio e maior tempo de suspens?o nos equinos avaliados na esteira, de 0,21s e 0,38s, respectivamente. O comprimento da passada foi semelhante (p>0,05) nos equinos avaliados em esteira e em pista de areia, por?m a velocidade de transi??o obteve maior valor nos equinos avaliados na esteira, de 4,03m/s em rela??o ? avalia??o em pista de areia, de 3,2m/s. Conclui-se a partir da morfometria os equinos foram enquadrados no padr?o de sela em mediol?neos e hiperm?tricos e na cinem?tica a ?nica vari?vel que se manteve com valor maior na esteira em todas as transi??es foi o tempo de suspens?o, j? o comprimento da passada e a velocidade da passada apresentaram maiores valores na esteira exceto nas transi??es esta??o-passo e trote-passo, o que pode esta relacionada a influ?ncias n?o definidas no estudo.

Disserta??o (Mestrado em Ci?ncia Florestal) ? Universidade Federal dos Vales do Jequitinhonha e Mucuri, Diamantina, 2015. O objetivo principal deste estudo foi avaliar a aplica??o de Redes Neurais Artificiais (RNA) utilizando a t?cnica Skip-layer connections, com e sem recorr?ncia, para estima??o do volume individual e da altura total de ?rvores de eucalipto. Os objetivos espec?ficos foram testar e avaliar as redu??es no tamanho da base de dados do conjunto de ajuste (treinamento) para estima??o dessas vari?veis. Os dados utilizados foram provenientes de ?rvores abatidas para cubagem (estima??o do volume individual) e de medi??es de parcelas permanentes de invent?rios florestais cont?nuos (estima??o da altura total), em ?rea de povoamentos de eucalipto localizados no sul da Bahia, Brasil. Foram treinadas redes do tipo Multilayer Perceptron (MLP), utilizando a fun??o de ativa??o log?stica nas camadas intermedi?ria e de sa?da e oito neur?nios na camada oculta. O n?mero de neur?nios na camada de entrada variou conforme o n?mero e o tipo de vari?vel (qualitativa ou quantitativa) em cada estudo. Os crit?rios de parada foram o erro m?dio quadr?tico de 0,0001 ou 3.000 ciclos (?pocas). Em seguida, as RNA selecionadas foram aplicadas em parte dos dados separados, para generaliza??o (valida??o). O software utilizado para o treinamento e a generaliza??o das RNA foi o NeuroForest 3.3. Para compara??o dos resultados obtidos pelas RNA, foram ajustados os modelos tradicionais de regress?o tanto para volume, quanto para altura, e tamb?m foram treinadas e aplicadas RNA usando o algoritmo Resilient Propagation, comumente utilizado em aplica??es da mensura??o florestal. A avalia??o dos resultados gerados pelas RNA e pelos modelos de regress?o foi feita por meio do coeficiente de correla??o entre os valores observados e estimados, de gr?ficos de dispers?o e de histogramas de frequ?ncia percentual dos erros percentuais. As Redes Neurais Artificiais utilizando Skip-layer connections apresentaram resultados satisfat?rios para estima??o de volume e de altura de ?rvores de eucalipto, o que evidencia a possibilidade de aplicar a t?cnica em mensura??o e manejo florestal e uma expressiva redu??o das bases de dados para treinamento das RNA. / Disserta??o (Mestrado) ? Programa de P?s-Gradua??o em Ci?ncia Florestal, Universidade Federal dos Vales do Jequitinhonha e Mucuri, 2015. / ABSTRACT SILVA, Paula Ventura da, M.Sc. Artificial neural networks with skip-layer connections in forest measurement. 2015. 46 f. Dissertation (Master in Forest Science) ? Universidade Federal dos Vales do Jequitinhonha e Mucuri, Diamantina, 2015. The aim of this study was to evaluate the application of Artificial Neural Networks (ANN) using the Skip-layer connections technique, with and without recurrence, to estimate the individual volume and total eucalyptus trees height. Its specific objectives were to test and evaluate reduction in the size of the adjustment assembly database (training) for estimating these variables. The data came from trees felled for scaling (estimation of individual volume) and measurements of permanent plots of continuous forest inventories (estimation of the total height), in eucalypt plantation area located in the south of Bahia, Brazil. Multilayer Perceptron (MLP) network type, using the logistic activation function in the intermediate and output layers and eight neurons in the hidden layer, were trained. The neurons number in the input layer varied according to the number and type of the variable (qualitative or quantitative) in each study. The stopping criteria were the root mean square error 0.0001 or 3,000 cycles (seasons). The software used for the RNA training and generalization was the NeuroForest 3.3. To compare the results obtained by RNA, traditional regression models were set for both the volume and the height, as well as RNA were trained and applied using the Resilient Propagation algorithm, commonly used in forest measurement applications. The evaluation of the results generated by the RNA and by the regression models was made via the correlation coefficient between observed and estimated values, scatter plots and histograms percentage frequency of the percentage errors. Artificial Neural Networks using Skip-layer connections showed satisfactory results for the estimation of volume and eucalyptus trees height, demonstrating the possibility of applying the technique in measuring and forest management and a significant reduction of databases for RNA training.

Das Verhältnis von ₵ und C im mensuralen Notationssystem des 15. bis zum beginnenden 17. Jahrhundert ist nicht befriedigend geklärt. Einer riesigen Menge musikschriftlicher Quellen, die von einer halbierenden / verdoppelnden Relation beider Zeichen sprechen, stehen zeitgenössische musikalische Quellen gegenüber, in denen dies musikpraktisch nicht funktioniert; in der modernen Debatte und Auseinandersetzung mit diesen Zeichen steht dieser eindeutigen Aussage ein mittlerweile verbreitetes Verständnis gegenüber, das außerhalb simultaner Kontexte eine unbestimmte, geringe Beschleunigung als Bedeutung des Zeichens ₵ behauptet, abgeleitet aus wenigen zeitgenössischen Quellen. Die vorliegende Monographie hat sich zum Ziel gesetzt, mehr Klarheit in dieses unscharfe Bild zu bringen. Methodisch geht sie dabei den Weg traditionsgeschichtlicher Analysen möglichst aller verfügbaren musikschriftlichen Quellen, welche sie einerseits spezifisch auf die Frage nach dem Verhältnis der beiden genannten Mensurzeichen samt verwandter Zeichen und zugehöriger Phänomene untersucht, welche sie aber andererseits darüber hinaus immer auch als ganze im Blick hat. Die Beschränkung auf musikschriftliche Quellen ergibt sich rein quantitativ aufgrund der schieren Menge und sachlich aufgrund der genannten Diskrepanz zu musikalischen Quellen, die eine separate Untersuchung beider Quellentypen je für sich fordert. Dabei werden musikalische Quellen gleichwohl immer so weit berücksichtigt, insofern sie von den musikschriftlichen Quellen selbst geboten werden, direkt als Beispiele oder indirekt durch Verweise. Die musikschriftlichen Quellen werden aber nicht nur für sich untersucht, sondern im Rahmen ihrer Kontexte, insbesondere gegenseitiger Verbindungen und Abhängigkeiten oder in ihrer Originalität. Das macht die Reichweite und das Gewicht einzelner Darstellungen und Aussagen überhaupt erst taxierbar, legt Traditionslinien, Entwicklungen und Abbrüche von Ideen und Konzepten offen und deckt so ein Netzwerk der musikschriftlichen Darstellungen auf, durch das die Gegenstände der musikalischen Lehre auf verschiedene Weise und in teils wechselnder Gestalt diffundieren. Die Untersuchung zeigt, dass – was den musikschriftlichen Diskurs angeht – die Behauptung einer verdoppelnden / halbierenden Bedeutung von ₵ von äußerst wenigen Ausnahmen abgesehen einerseits eindeutig ist, andererseits aber auf bestimmte Kontexte beschränkt. Außerhalb dieser Kontexte ist ₵ als eine Variante des Grundzeichens C mit derselben mensuralen Bedeutung ohne zusätzlichen Informationsgehalt anzusehen. / The ratio of ₵ and C in mensural notation of the 15th to the beginning of the 17th century has not yet been satisfactorily clarified. A plethora of theoretical sources which claim a meaning in the sense of halving / doubling in the ratio between these two signs stands against contemporary musical sources in which this does not work; in the modern debate about these signs, this clear meaning opposes a meanwhile common understanding of ₵ – except simultaneous relationships – as a sign for an undefined moderate acceleration which is based on very few contemporary sources. The present monograph aims to bring more clarity in this blurred picture. The methodological approach is “traditionsgeschichtlich”, which means that all available theoretical sources as far as possible are investigated specifically concerning the ratio of the two mentioned signs, related signs and phenomena, but that beyond this they also are regarded as a whole. The limitation to theoretical sources is due to the huge amount of them and, as regards content, due to the discrepancy to musical sources mentioned above, which demands a separate investigation. In doing so, musical sources are considered nevertheless, insofar they are provided by the theoretical sources themselves, directly as examples or indirectly by reference. In addition, the theoretical sources are not investigated just as such but in their contexts, especially concerning interconnections, dependencies, or their originality. Only on that grounds the weight and scope of single statements and views can be assessed, traces of transmission and tradition, evolutions and abortions of ideas and concepts can be detected. Thus, a network of theoretical sources can be retraced in which the issues of musical theory and teaching move in different manner and in partly different shape. The investigation shows that – concerning the discourse of theoretical sources – the assertion of a halving / doubling meaning of ₵ is, with very few exceptions, unambiguous but limited to certain contexts. Outside these contexts, ₵ is to be regarded as a variant of the sign C with the same mensural meaning and without any further information.
