Three experimental methods to validate the design via Finite Elements were used: method for determining the impedance with AC voltage, the rising time method of DC current phase and falling time of DC current phase method. All tasks of simulation and measurement were performed using a personal computer. To perform the design simulation a numeric simulation software was used with finite element analysis (CST STUDIO SUITE TM 2010Â) in three dimensions, using both, tetrahedral and hexahedral meshes. For measurement tasks also a data acquisition board (DAQ) integrated with two interfaces was used: the LabView and Signal Express both developed by the same manufacturer of the acquisition board (National Instruments) aiming to determine the inductance per phase of the VRRM. From the values obtained of inductance per phase the flux linkage per phase was calculated. Graphs of flux linkage with current and inductance profiles for seven positions are shown and compared with the simulation FEA. Tables showing the values of some differences between the methods in terms of percentage are presented and discussed. An evaluation of all methods was done, showing positives and negatives aspects, limitations and suggestions to improve them. The machine was a studied Variable Reluctance Rotating Motor 6/4 (6 stator poles and 4 poles on the rotor), three-phase, 1 hp, rated current of 10A and speed of 2.000 rpm, designed by the Research Group on Automation and Robotics, Department of Electrical Engineering, Federal University of CearÃ.

Gladiola (Gladiolus x grandiflorus Hort.) is an important cut flower cultivated under field conditions. The air temperature is the main abiotic factor that drives their phenology, therefore the scheduling flowering of gladiola for target markets by defining the optimum planting date. The objective this study was determine the optimum planting date of gladiola aiming harvest spikes for selling on All Souls’ Day and Mother’s Day under current climate and in CMIP5 scenarios in the Rio Grande do Sul State. The PhenoGlad model was used for simulates the developmental stages of gladiola and plant injuries by heat and frost. For simulates the optimum planting date under current climate, input data in the model was minimum and maximum daily temperature of 55 years (1961-2015) from eighteen weather stations across the State. Once optimum planting date was simulated for each maturation group and weather station, with all years, the planting date was averaged for each El Niño Southern Oscillation (ENSO) phases to access the ENSO effect on the optimum planting date of gladiola. For simulates the optimum planting date under climate scenarios, input data in the model was minimum and maximum daily temperature of the 32 grid points in the State, for RCP2.6, RCP4.5 and RCP8.5 scenarios. The optimum planting date in the future period (2070-2098) was presented as anomalies (difference between the optimum planting date and average optimum planting date in the baseline period (1976-2005) for each grid point and maturation group. The percentage of years with damage was also presented as anomalies. The phenomenon ENSO affects the optimum planting date of gladiola for harvesting on All Souls’ Day. For this growing season, planting date was anticipated for La Niña years (low temperatures) and delayed for Very Strong El Niño (high temperatures). For Mother’s Day, only Very Strong El Niño events affect the development of the gladiola, but different of the growing season for All Souls’ Day, planting date was anticipated for Very Strong El Niño years, and delayed for others ENSO phases. As well as for Very Strong El Niño years, for harvesting on All Souls’ Day, the optimum planting date was delayed in the climate scenarios, due to shortening of the cycle on rising temperatures conditions. For Mother’s Day, the average air temperature exceeded the optimum temperature of the crop in the warmest regions of the State. In these regions, the anomalies of the optimum planting date were negatives because the development rate decreased, delaying flowering. The risk of injuries by heat is more severe in the growing season for harvesting on All Souls’ Day, mainly in the scenario RCP8.5 and warmest regions, where the anomalies reached +70% of years. This results will provide subsidies for the production expansion for others regions of the State in order to harvesting spikes for selling on All Souls’ Day and Mother’s Day. / O gladíolo (Gladiolus x grandiflorus Hort.) é uma importante flor de corte cultivada a céu aberto. A temperatura do ar é o principal fator abiótico que dirige sua fenologia, portanto os agricultores agendam o florescimento de gladíolo para os picos de demanda, definindo a data ótima de plantio. O objetivo desse estudo foi determinar a data ótima de plantio de gladíolo visando colheita das espigas para comercialização no Dia de Finados e Dia das Mães no clima atual e em cenários climáticos do CMIP5 no Rio Grande do Sul. O modelo PhenoGlad foi usado para simular os estágios de desenvolvimento do gladíolo e danos nas plantas por calor e geada. Para simular a data ótima de plantio no clima atual, os dados de entrada no modelo foram temperatura mínima e máxima diária do ar de 55 anos (1961-2015) de dezoito estações meteorológicas distribuídas no estado. Uma vez que a data ótima de plantio foi simulada para cada grupo de maturação e estação meteorológica, com todos os anos, foi realizada a média da data ótima de plantio para cada fase do El Niño Oscilação Sul (ENOS) para acessar o efeito do fenômeno na data ótima de plantio de gladíolo. Para simular a data ótima de plantio nos cenários climáticos, os dados de entrada no modelo foram temperatura mínima e máxima diária do ar de 32 pontos distribuídos no estado, para os cenários RCP2.6, RCP4.5 and RCP8.5.A data ótima de plantio no período futuro (2070-2098) foi apresentada como anomalias (diferença entre a data ótima de plantio do período futuro e a média da data ótima de plantio do período baseline (1976-2005) para cada ponto e grupo de maturação. A porcentagem de anos que ocorreu danos também foi apresentada como anomalias. O fenômeno ENOS afeta a data ótima de plantio de gladíolo para colheita no Dia de Finados. Neste período de cultivo, a data de plantio foi antecipada em anos de La Niña (temperaturas baixas) e atrasada em anos de El Niño muito forte (temperaturas altas). Para o Dia das Mães, somente eventos de El Niño muito forte afetaram o desenvolvimento do gladíolo, mas diferente do período de cultivo de Finados, a data de plantio foi antecipada para anos de El Niño muito forte e atrasada para as demais fases do ENSO. Assim como para anos de El Niño muito forte no cultivo de Dia de Finados, a data ótima de plantio foi atrasada nos cenários climáticos devido ao encurtamento do ciclo em condições de aumento de temperatura. Para o período de cultivo de Dia das Mães, a temperatura média ultrapassou a temperatura ótima da cultura nas regiões mais quentes do estado. Nessas regiões, as anomalias de data de plantio foram negativas porque a taxa de desenvolvimento diminuiu, atrasando a floração. O risco de danos nas espigas por calor é maior no cultivo de Dia de Finados, principalmente no cenário RCP8.5 e nas regiões mais quentes, onde as anomalias atingiram +70% dos anos. Esses resultados proporcionarão subsídios para a expansão da produção de gladíolo para outras regiões do estado, visando colheita das hastes para comercialização no Dia de Finados e no Dia das Mães.

FAPEMIG - Fundação de Amparo a Pesquisa do Estado de Minas Gerais / A fragilização por hidrogênio tem sido um problema constante em diferentes setores da indústria. Por ser o menor átomo existente, o hidrogênio difunde-se na microestrutura dos materiais metálicos, inserindo tensões mecânicas internas que podem, eventualmente, levar a uma falha catastrófica. Atualmente, os métodos mais comuns existentes para analisar este fenômeno são lentos e caros, configurando-se assim a necessidade de desenvolver um método de ensaio que não possua tais desvantagens. No presente trabalho, apresenta-se o desenvolvimento de um equipamento cuja função é avaliar de forma rápida a susceptibilidade à fragilização por hidrogênio (SFH) dos materiais metálicos através de ensaios de carregamento progressivo em meio assistido (RSL). Este equipamento apresenta uma grande vantagem em relação aos outros métodos avaliação da SFH, que é o menor tempo de ensaio para se ter resultados representativos. Na presente dissertação foram realizadas a concepção, projeto, simulação em elementos finitos, construção e validação do equipamento. Sua validação foi realizada ensaiando-se uma amostra sem entalhe,cuja tensão mecânica medida foi comparada com aquela retornada pelo software do RSL. Além disso, foi calculada a incerteza de medição relacionada ao cálculo da tensão mecânica na amostra. Os ensaios de verificação do desempenho do RSL foram realizados em amostras de aço AISI 4140 beneficiado com dureza de 40HRC, onde foi avaliada a relação entre o nível de potencial catódico aplicado e a SFH do material das amostras. Os resultados obtidos na validação do equipamento mostraram erros inferiores a 1%. Os resultados mostraram um aumento da SFH com o aumento da dureza indicando que há uma elevada sensibilidade da SFH em relação à dureza da amostra. Os ensaios com variação do potencial catódico mostraram uma relação direta entre esse parâmetro e a SFH da amostra, havendo uma saturação na SFH a partir de -1,1 VAg/AgCl. / Hydrogen embrittlement of metallic materials has been a frequent problem in different industry sectors. Because it is the smallest existing atom, hydrogen diffuses into the microstructure of metallic materials, resulting in internal mechanical stresses that may eventually lead to a catastrophic failure. The most common methods available to analyze this phenomenon are time consuming and expensive. For this reason, it is desired to develop a test method that does not have such disadvantages. In this work it is presented the development of an equipment to rapidly evaluate the susceptibility to hydrogen embrittlement (SHE) of the metallic materials using the rising step load (RSL) bend testing in assisted environment. This equipment has a great advantage over the other evaluation methods of SHE, which is the shortest test time to have representative results. The validation of the infrastructure was performed by testing bars without notches to, whose measured mechanical stress was compared with that returned by the RSL software. In addition, the measurement uncertainty related to the calculation of the mechanical stress in the sample was calculated. The tests to verify the performance of the RSL equipment were carried out on samples of steel AISI 4140 heat treated to a hardness of 40HRC. The effect of the cathodic potential applied to notched bars of AISI 4140 on the SHE was evaluated. The results obtained in the validation phase of the equipment showed errors lower than 1%. The results showed also an increase in SHE with increasing material hardness indicating that there is a high sensitivity to the SHE with respect to the hardness of the sample. The tests carried out using cathodic potential variation showed a direct relationship between this parameter and the SHE of the sample, with saturation of the SHE at -1.1 VAg/AgCl. / Dissertação (Mestrado)

Attempts to quantify the effects of ocean acidification and warming (OAW) on scleractinian corals provide a growing body of response measurements. However, placing empirical results into an ecological context is challenging, owing to variations that reflect both natural heterogeneity and scientific bias. This study addresses the heterogeneity of climate change induced changes in coral recruitment and calcification. To discern scientific bias and identify drivers of the remaining heterogeneity, 100 publications were analyzed using a combination of weighted mixed effects meta-regression and factorial effect size meta‑analysis. A linear model was applied to quantify the variation caused by differing stress levels across studies. The least squares predictions were then used to standardize individual study outcomes and effect size meta-analysis was performed on original and standardized outcomes separately. On average, increased temperature significantly reduces larval survival, while ocean acidification impedes settlement and calcification. Coral resistance to OAW is likely governed by biological traits (genera and life cycle stage), environmental factors (abiotic variability) and experimental design (feeding regime, stressor magnitude, and exposure duration). Linear models suggest that calcification rates are driven by carbonate and bicarbonate concentrations, which act additively with warming. Standardizing outcomes to linear model predictions proved useful in discerning strong sources of scientific bias. The approach used in this study can improve modelling projections and inform policy and management on changes in coral community structure associated with the expected future intensification of OAW.

Due to climate change and natural variations in the hydrological cycle, global mean sea levels are increasing, causing the mean sea levels in different regions of the world to increase. In Sweden, coastal cities are facing rising water levels which is increasing flooding. The coastal community of Gothenburg, Sweden was identified the 18th most vulnerable city in the country both to flooding induced by water level rise and other climate change related impacts. Its location, in proximity of Lake Vänern, and in the mouth of the Göta River and its tributaries: Säveån, Mölndalsån and Lärjeån is heightening flood risk and vulnerability in the area. This thesis aims to contribute in comprehending the integration process of natural hazard and climate change adaptation for flood management in Älvstaden- central Gothenburg between 1999 and 2015. With the main objectives being” how the municipality of Gothenburg has applied the urban land use planning theory for the integration of natural hazard and climate change adaptation, with regards to adaptation for flood management in Älvstaden between 1999 and 2015? “What climate change adaptation policies for flood management have been implemented in Gothenburg within this time frame, and how the policies have been revised to match the reality of flood issues?” And “What improvements would be made in the integration process to better address adaptation for flood management?” A desk-based research and one case study approach was adopted for this study. The findings indicate that although the city has systematically used the steps involved in the integration process of natural hazard and climate change adaptation for flood management, it does not link the policies and the measures applied to adaptation for flood management. Which is an issue as it has led to the exclusion of vital functions of the integration process. Suggestions on how the integration process could be improved are provided.

Ce travail présente une étude de la dynamique interfaciale de gouttes oscillantes dans une plage étendue de fréquences, en particulier dans le domaine des hautes fréquences. Nous avons développé une méthode de caractérisation de la dynamique des oscillations de gouttes, en présence d’un forçage externe imposé, sous la forme de variations de volume périodiques de faible amplitude sur une goutte attachée à l’extrémité d’un capillaire. Cette méthode permet d’identifier les modes d’oscillation des gouttes et d’en mesurer les fréquences et les taux d’amortissement. Cette méthode a été appliquée à différents systèmes liquide-liquide, en l’absence ou en présence de surfactants. Dans ce dernier cas, elle permet d’évaluer l’effet du comportement viscoélastique des interfaces sur la dynamique des oscillations. Ainsi 3 types d’interfaces ont été identifiés. Pour les interfaces de premier type (heptane/eau sans ajout de surfactant), chaque mode propre est modélisé par un oscillateur linéaire peu amorti. Les fréquences propres et les taux d’amortissement sont bien prédits par la théorie linéaire. Les interfaces de types 2 et 3 sont obtenues en ajoutant du pétrole brut à la phase dispersée. Les surfactants naturellement présents dans le pétrole (asphaltènes, résines) s’adsorbent à l’interface et lui confèrent des propriétés viscoélastiques. Pour les interfaces jeunes (type 2, moins de 20 minutes de vieillissement), les fréquences propres mesurées restent bien prédites par la théorie, qui considère des interfaces non contaminées, tandis que les taux d’amortissement sont de loin supérieurs aux valeurs théoriques. D’autre part, les interfaces vieillies (type 3) présentent des modes propres différents avec des fréquences de résonance supérieures à celles des interfaces jeunes. Dans ce cas, la dynamique de l’interface à haute fréquence est régie par l’élasticité du réseau formé par les espèces amphiphiles du pétrole brut. Les oscillations libres d’une goutte en ascension dans une phase externe stagnante, pour un système liquide-liquide sans ajout de surfactants, ont été étudiées. Les valeurs mesurées de la fréquence d’oscillation des 4 premiers modes sont en adéquation avec la théorie linéaire. Cependant les valeurs mesurées du taux d’amortissement sont très élevées par rapport aux valeurs théoriques, pour une interface non contaminée. En effet, des espèces résiduelles adsorbées à l’interface provoquent l’apparition d’un gradient de tension interfaciale par effet Marangoni et par suite une production de vorticité plus intense dans les couches-limites, ce qui conduit à l’augmentation de l’amortissement des oscillations. / We present an experimental study of oscillating drop interfacial dynamics at a wide frequency range, especially at high frequency. A characterization method of drops oscillation dynamics has been developed. The oscillations are generated by imposing low amplitude periodic variation of volume to a drop which is attached to a capillary tip. The present method is based on the identification of the drop eigenmodes and the determination of their frequencies and damping rates. It has been applied to characterize several liquid-liquid systems. Three types of interface have been identified. For interfaces of type 1 (heptane/water without added surfactant), each eigenmode is modelled by a weakly damped linear oscillator. Eigenfrequencies and damping rates are well predicted by the linear theory. Interfaces of Types 2 and 3 are obtained by adding crude oil to the disperse phase. Oil native surfactants (asphaltenes, resins) adsorb on the drop interface and provide the latter with viscoelastic behaviour. For young interfaces (type 2 with aging time below 20 minutes), eigenfrequencies remain well predicted by the theory, which deals with non contaminated interfaces, whereas the measured damping rates are significantly higher than the theoretical values. On the other hand, aged interfaces (type 3) exhibit different eigenmodes, of which eigenfrequencies are much higher than the resonance frequencies measured for the young interfaces. At high frequency, the dynamics of aged interfaces are governed by the elasticity of the network constituted by the crude oil amphiphilic species, while the dynamics of young interfaces are governed by interfacial tension. Freely decaying oscillations of a rising drop in a liquid at rest without added surfactant were also considered. Measured frequencies for the first four eigenmodes are in good agreement with the linear theory. However, measured damping rates are much higher than the theoretical rates for non contaminated interfaces. In fact, residual adsorbed species at the heptane/water interface induce Marangoni effects and thus gradients of interfacial tension. Therefore, vorticity production within the boundary layers is enhanced, which explains the observed increase of the oscillation damping rates.

The arrest of Meng Wanzhou and the Huawei prosecution have revealed a mounting battle for high-tech supremacy between the United States and China. The ongoing technology war and the trade war are merely one dimension of a far-reaching and accelerating imperialist rivalry. The changing reality on the world stage has urged a reconsideration of the thesis of transnational capitalist class (TCC) and theory of globalization in general. By reviewing the historical debate between the globalist and critical realist schools, I argue that William Carroll’s theoretical frame of global capitalism grounded in corporate network research through emphasizing a dialectical process of the ‘making’ of the TCC is better equipped to explain the unfolding Sino-U.S. conflict. Following Carroll’s multilayered approach to corporate network research, I conduct a corporate network analysis to examine the directorate interlocks of 40 Chinese transnational corporations (TNCs) selected from the Fortune Global 500 list. My study has found that the transnational networks of Chinese TNCs have remained considerably sparse, contained within condensed national networks. The globalization of Chinese TNCs and Chinese corporate elite has been modest and has not undermined or replaced the national base. This is due to two crucial reasons: the statist character of Chinese capitalist class and the regionalized development of global capitalism and class formation. In concordance with Carroll’s network research of Western companies, my study of corporate China reaffirms the fragility of the TCC, its internal friction, and potential decomposition. It also provides a material ground for analyzing the Sino-U.S. inter-imperialist rivalry as a structural development out of global capitalism and its class relations. My thesis study, therefore, offers the first attempt to draw a direct linkage between corporate network formation and geopolitical conflict. / Graduate
