Повний текст джерелаIn engineering it is always looked to construct resistant structures, safe and economically viable. The safe and economic project of the structures is function of the imposed actions; in the case of silos it does not have a Brazilian norm that it prescribes on its projects and action, moreover, some divergences are observed between the foreign norms. This main work as objective the comparative analysis of the lapsings of the international norms: ENV (1995), the 3774 (1996), ACI 313 (1991), DIN 1055 (1987) and BMHB (1985), becoming an analysis statistics between them, being elaborated an electronic spread sheet of calculation of the pressures, being able itself to vary the properties, to facilitate to the analysis and the development of an theoretician-experimental study. It still has as purpose to present a theoretical study of the pressures in vertical silos, for this, a state of the art of the theories of pressures proposals for the most important researchers was developed and finally the modeling of a silo to be analyzed through Ansys® software. The comparative analysis statistics of the main foreign norms showed the existence of sufficiently significant differences between the gotten values, being that in the case of the horizontal pressures it has differences of up to 59% (between norm BMHB and DIN) and that in the average the lesser values are gotten in the British and the greaters in the German. It was still verified that the majority of the foreign norms adopts the theory of Janssen for the determination of the horizontal pressures. In relation to the vertical pressures, the difference between the norms arrived 400% almost (between norms ENV and), in average the lesser values is gotten in the European norm and the greaters in the Australian, were still observed that the model of Janssen, without no alteration are considered by norm ACI. E in the case of the pressures of attrition with the wall the lesser values are gotten in norm BMHB and the greaters in the DIN, having arrived themselves it 59% differences (between norm BMHB and DIN). In relation to the use of the Ansys® program an initial plan of modeling of a silo was sketched, observing itself that the program and the methodology are useful, being able itself to make a refinement, to compare the results and to vary the in agreement pressure the diverse existing norms, being able to be developed in a future work, becoming a comparative degree between practical theoretician and with silo use archetype and cells of pressure.
Na engenharia, procura-se sempre construir estruturas resistentes, seguras e economicamente viáveis. O projeto seguro e econômico das estruturas é função das ações impostas; no caso de silos, não há uma norma brasileira que prescreva sobre seus projetos e ações, além disso, algumas divergências são observadas entre as normas estrangeiras. Este trabalho tem como objetivo principal a análise comparativa das prescrições das normas internacionais: ENV (1995), AS 3774 (1996), ACI 313 (1991), DIN 1055 (1987) e BMHB (1985), fazendo-se uma análise estatística entre elas, sendo elaborada uma planilha eletrônica de cálculo das pressões, podendo-se variar as propriedades, facilitar a análise e o desenvolvimento de um estudo teórico-experimental. Tem ainda como finalidade apresentar um estudo teórico das pressões em silos verticais, para isso, um estado da arte das teorias de pressões propostas pelos mais importantes pesquisadores foi desenvolvido e por último a modelagem de um silo para ser analisado através do software Ansys®. A análise comparativa estatística das principais normas estrangeiras mostrou a existência de diferenças bastante significativas entre os valores obtidos, sendo que no caso das pressões horizontais há diferenças de até 59% (entre norma BMHB e DIN) e que na média os menores valores são obtidos na Britânica e os maiores na Alemã. Verificou-se ainda que a maioria das normas estrangeiras adota a teoria de Janssen para a determinação das pressões horizontais. Em relação às pressões verticais, a diferença entre as normas chegou a quase 400% (entre normas ENV e AS), em média os menores valores são obtidos na norma Européia e os maiores na Australiana, observou-se ainda que o modelo de Janssen, sem nenhuma alteração é proposto pela norma ACI. E no caso das pressões de atrito com a parede os menores valores são obtidos na norma BMHB e os maiores na DIN, chegando-se a diferenças de 59% (entre norma BMHB e DIN). Em relação ao uso do programa Ansys® esboçou-se um plano inicial de modelagem de um silo, observando-se que o programa e a metodologia são úteis, podendo-se fazer um refinamento, comparar os resultados e variar a pressão conforme as diversas normas existentes, podendo ser desenvolvido em um trabalho futuro, fazendo-se um comparativo entre teórico e prático com uso de silo protótipo e células de pressão.

Meteorologiska förhållanden har en stor påverkan på ljudutbredning utomhus. De atmosfäriska effekterna är absorption, refraktion och turbulens, dessa verkar samtidigt och kan vara svåra att skilja åt. Gradienter i temperaturen och vinden gör att ljudhastigheten varierar med höjden. Ljudet kommer då att böjas av nedåt eller uppåt från marken. Kunskapsläget inom vart och ett av dessa områden presenteras i denna studie.
28 stycken trafikbullermätningar har utförts längs den nya E4:an norr om Uppsala vid varierande meteorologiska förhållanden. Mätningarna visar att den totala meteorologiska inverkan på ljudnivån kan vara så stor som 18 dBA vid 132 meters avstånd över snötäckt mark. Temperaturgradientens påverkan på samma avstånd bedöms kunna vara 6 dBA och turbulensens 2 dBA. Spridningen av ljudnivåerna är större i motvinds- än medvinds-utbredning. Detta kan förklaras genom att markdämpningen får mer varierande inflytande i förstnämnda fall.
Svenska myndigheter har inte tagit hänsyn till meteorologins påverkan på ljudnivåerna, vid bulleranalyser, förrän nyligen. En modell- Nord 2000 har utvecklats som sägs kunna förutsäga vägbuller under varierande meteorologiska förhållanden. Utvärdering av modellen visar dock stora brister. Modellen klarar av att förutsäga medelvärden under ett år med bra noggrannhet, men denna rapport visar att modellen misslyckas med variationerna under kortare tidsperioder. Detta är allvarligt, då det lika ofta som en hög medelnivå är just variationerna i form av toppar i ljudbilden som upplevs som störande. 10 minuters mätningarna i motvindsutbredning visar att modellens fel kring en trafikerad väg kan vara så stort som 8 dBA på 132 m avstånd.

Повний текст джерелаTidal flat is a special environment suffering tidal regime in which tidal flats are submerged during flood tide and exposing the air during ebb tide. Tidal flats in the north coast in Vietnam are constituted in diurnal tide condition with tide range varying from 0.3m to 3.5m. Along 350km coastline of the study area, the diversity of constituent conditions formed various tidal flats with different characteristic. Tidal flats in the southern part of the study area are fed by sediment from two large river systems, in the middle part forms the coal tidal flats, but the only sandy sediment along with tide domination constitute the large tidal flats in the north coast of the study area. This study apply remote sensing techniques and GIS tools to solve four scientific issues including: the evolution of tidal flats over periods from 1989 to 2014, the characteristics of sediments in tidal flats, the surface parameter of tidal flats, and the forcing factors which influence the future change of tidal flats. The results of the study shows that, tidal flats in the north coast in the study area are dramatically eroded but the tidal flats in the south coast are deposition by the concentration of fine sediments. In total 14 forcing factors, the coastal nature factor has highest forcing to the deposition of tidal flats. However, the factors of wind-wave effect and tidal flat width have negative influence to deposition. Consequently, the highest potential for future deposition of tidal flats are around the river mouths in the south coast but no potential for future deposition is in tidal flats in the north of the study area. This study is implemented in the framework of the cooperation between University of Science and Technology Ha Noi (USTH) and Université de Reims Champagne-Ardenne (URCA)

Повний текст джерелаThe North West African upwelling system off Morocco, Mauritania, Gambia and Senegal is the most productive system in the world in terms of primary productivity. This productivity results in a large fish biomass dominated by small pelagic fish which are the main living resources exploited in the region. In a context of shared management of fisheries resources by several countries in the region, understanding the factors that control the spatial distribution of populations of small pelagic fish and the evolution of their abundances is a crucial issue for fisheries and the socio-economic development of the region. The main objective of this thesis is to describe the seasonal and interannual variations of the marine environment of the Canary upwelling along the Northwest coast of Africa and to link these variations with the spatio-temporal dynamics of the main small pelagic species of commercial importance of this zone. We have used different sets of data available and developed different approaches in order to have a complete view of the functioning of this ecosystem. Thus, we have combined satellite data, acoustic scientific survey data, fishing statistics and analysis of otolith shapes. Along th NW African coasts ( 10° - 35° N), our data allowed us to identify three regions with a well-differentiated seasonality and intensity of upwelling. The region has a high latitudinal and temporal variability of environmental conditions. The southern part of the zone (between 10° and 24° N) is characterized by warmer and richer Chlorophyll-a waters than the northern part. The majority of the variability of the environmental parameters studied is due to seasonality (> 60%). During the study period (2002-2012), we noted a significant warming trend ranging from 0.01° C to 0.04°C. yr-¹ and a general reinforcement of ipwelling, but a downward trend in Chl a concentration in the whole study area. There is a south-north latitudinal gradient of the phenology of the phytoplankton bloom (period, duration and magnitude of the bloom). However, there are no significant interannual trends in phytoplankton bloom phenology or correlations or trends with the physical parameters of the environment studied (SST, upwelling index, wind). The Canary current ecosystem is characterized by the sardine/ Sardinella pair, Anchovy, althought present in this ecosystem, plays no more important role than in other upwelling systems. The relationships between the abundances of anchovies, sardines and sardinella with environmental parameters have been studied at different scales using generalized additive models (GAM). The results of our study indicate that the spatial and temporal variations of the abundance of anchovy and sardinella are controlled more by the thermal gradient than by the biological productivity. The sardine seems to be more controlled by an "optimal upwelling and temperature windows". We were able for the first time to demonstrate the existence of a temporal alternation of abundance between anchovy and sardine as is known in other upwelling systems. Finally, in order to contribute to the knowledge of population structure of the round sardinella that concern scientists and fisheries managers, we conducted a study of the shape of otoliths. The possible existence of several stocks of sardinella in connection with oceanographic structures do not support the current management policy which considers a single stock off the African NW coast

Повний текст джерелаLet Y be a Gaussian vector distributed according to N (m,sigma²Idn) and X a matrix of dimension n x p with Y observed, m unknown, sigma and X known. In the linear model, m is assumed to be a linear combination of the columns of X In small dimension, when n ≥ p and ker (X) = 0, there exists a unique parameter Beta* such that m = X Beta*; then we can rewrite Y = Beta* + Epsilon. In the small-dimensional linear Gaussian model framework, we construct a new multiple testing procedure controlling the FWER to test the null hypotheses Beta*i = 0 for i belongs to [[1,p]]. This procedure is applied in metabolomics through the freeware ASICS available online. ASICS allows to identify and to qualify metabolites via the analyse of RMN spectra. In high dimension, when n < p we have ker (X) ≠ 0 consequently the parameter Beta* described above is no longer unique. In the noiseless case when Sigma = 0, implying thus Y = m, we show that the solutions of the linear system of equation Y = X Beta having a minimal number of non-zero components are obtained via the lalpha with alpha small enough

Повний текст джерелаThis paper analyses the trajectory of empty subjects and overt subjects in the standard language of the elite of São Paulo from the late XIX century to 1930s, when that city received a large influx of immigrants, who were speakers of languages with null subject . Starting from a critic assessment of the \"parametric variacionism\", based on Labov and Chomsky, we propose the \"trans-systemic generativism\". From this perspective, language is generated in two levels: in the biological and innate level, the language faculty, after matured, endows the individual with \"linguistic competence\"; in the social level, the habitus, after internalized, provides the individual with \"linguistic capital\", as proposed by Bourdieu. Therefore we believe that there is a generative module that allows individuals to offer their products in the highly concentrated linguistic market. The analysis of the linguistic corpora led us to conclude that the elite, despite making more use of empty subject, was already boosting the use of overt subjects, a phenomenon well advanced in the caipira dialect. This behavior is explained by structural factors internal to language, and also expressed, from the social-historical standpoint, a clear choice of a linguistic form as opposed to the standard language of immigrants, as established by the habitus of the elite.

Milk is a highly nutritious agricultural product and the basis of a productive chain that generates employment and income, but its quality is historically deficient and seasonal in several regions of Brazil, affected mainly by climatic variations and production conditions. In order to improve the quality of this raw material, control measures and incentives have been implemented by the dairy sector, such as normative instructions and payment for quality. Regulatory criteria are very strict, but if milk quality is not legally satisfactory, it may not only affect industrial yield but also food security and producer remuneration. Thus, this study aims to evaluate the quality of raw milk refrigerated in relation to the legal framework and the effect of its seasonality on the price paid to producers. Results of monthly analyzes of fat, lactose, protein, total dry stratum (TDS), dry defatted stratum (DDS), somatic cell count (SCC) and total bacterial count (TBC) of 35,245 samples of milk from expansion tanks of the Catalan/GO Microregion. The averages were analyzed for variance and Tukey's test (p≤0.05) for comparison of means, considering the effects of the months, seasons and periods (dry and rainy) of the year, besides the legal parameters and model of Parameters for Milk Quality Payment (PMQP). According to legal parameters, the quality of refrigerated raw milk from expansion tanks was not adequate, as approximately 25% of the samples presented legal disagreement. The total bacterial count (TBC) was the only requirement whose geometric means were above the maximum limits allowed, and the somatic cell count (SCC) was reduced in the percentage of samples in legal compliance in the temporal period. The quality of the milk was better in the months of April to June (autumn) and in the dry period of the year, when it presented high physicochemical composition and reduced microbiological composition in relation to the other periods. Considering the 'Parameters for Milk Quality Payment' (PMQP) proposed in this study, the seasonality of milk quality influenced the price paid to producers, providing a subsidy of 3.8% to 6.9% in their remuneration. The biggest bonuses occurred in April and May, in the fall and dry period of the year, being the major contributions of fat and protein, while TBC caused a penalty. The results show that the main problems of the quality of refrigerated raw milk are those related to hygiene in the production and maintenance of the product and express the relevance of programs that penalize the goals not reached, but which also subsidize the quality of milk as an incentive for producers to produce Of good quality milk. Future studies are expected to be closer to the dairy farms and producers in order to guide and justify appropriate quality improvement programs for this raw material.
O leite é um produto agropecuário altamente nutritivo e base de uma cadeia produtiva geradora de emprego e renda, porém, sua qualidade é historicamente deficiente e sazonal em várias regiões do Brasil, afetada principalmente pelas variações climáticas e condições da produção. Visando melhoria da qualidade desta matéria-prima, medidas de controle e incentivos têm sido implementadas por órgãos do setor lácteo, tais como, instruções normativas e pagamento por qualidade. Os critérios normativos são bastante rígidos, mas caso a qualidade do leite não seja legalmente satisfatória, pode prejudicar não só o rendimento industrial, como também a segurança alimentar e a remuneração do produtor. Assim, este estudo tem por objetivo avaliar a qualidade do leite cru refrigerado em relação ao enquadramento legal e o efeito da sua sazonalidade sobre o preço pago aos produtores. Utilizou-se resultados de análises mensais de gordura, lactose, proteína, estrato seco total (EST), estrato seco desengordurado (ESD), contagem de células somáticas (CCS) e contagem bacteriana total (CBT) de 35.245 amostras de leite de tanques de expansão da Microrregião de Catalão/GO, coletadas entre 2006 a 2015. Submeteu-se as médias à análise de variância e teste de Tukey (p≤0,05) para comparação de médias, considerando-se efeitos dos meses, das estações e dos períodos (seco e chuvoso) do ano, além dos parâmetros legais e modelo de Parâmetros para Pagamento por Qualidade do Leite (PPQL). De acordo com os parâmetros legais, a qualidade do leite cru refrigerado de tanques de expansão não se apresentou adequada, pois cerca de 25% das amostras apresentaram desconformidade legal. A contagem bacteriana total (CBT) foi o único requisito cujas médias geométricas ficaram acima dos limites máximos permitidos, já a contagem de células somáticas (CCS) sofreu redução do percentual de amostras em conformidade legal, no período temporal. A qualidade do leite foi melhor nos meses de abril a junho (outono) e no período seco do ano, quando apresentou elevada composição físico-química e reduzida composição microbiológica em relação aos demais períodos. Considerando-se os 'Parâmetros para Pagamento por Qualidade do Leite' (PPQL) proposto neste estudo, a sazonalidade da qualidade do leite influenciou o preço pago aos produtores, proporcionando bonificação de 3,8% a 6,9% em sua remuneração. As maiores bonificações ocorreram em abril e maio, no outono e período seco do ano, sendo as maiores contribuições da gordura e proteína, enquanto a CBT causou penalização. Os resultados apontam como principais problemas da qualidade do leite cru refrigerado os relacionados à higiene na obtenção e manutenção do produto e expressam a relevância de programas que penalizam pelas metas não alcançadas, mas que também bonificam pela qualidade do leite como incentivo aos produtores para a produção do leite de boa qualidade. Estudos futuros devem se aproximar das unidades exploradoras do leite e dos produtores, a fim de nortear e fundamentar programas adequados de valorização da qualidade desta matéria-prima.

In this thesis, the dependence of the MEG source localization accuracies of the inverse algorithm Source Iteration of Minimum Norm(SIMN) on Tikhonov regularization parameter λ is studied and a method is proposed to estimate the Tikhonov regularization parameter λ. Numerical simulations show that the λ values that optimize the localization accuracies of SIMN depond on the Signal-to-Noise Ratio(SNR). To obtain a good estimate of λ a weighted sum of square of norms of minimum norm estimates of source amplitudes and noises is considered. It is shown numerically that, by a proper choice of the weighting factor, the λ value corresponding to the minimum of the weighted sum results in localization accuracy better than that using the λ value estimated from other methods.
