| 3 | 电力系统电流互感器饱和特性的柔性神经网络补偿法显示文摘电流互感器(CT)由于饱和使得副边电流变形,进而导致保护与测量应用中的许多问题。为此,提出一种补偿CT饱和特性的方法,以改善其测量性能。所提算法基于具有2个可变参数的sigmoid函数,构建了新型柔性神经网络,以估算CT励磁电流。实时地将估算所得励磁电流与扭曲的副边测量电流相加,即得补偿后原边电流。在学习过程中,所建补偿器的各柔性神经元柔性地改变其形状以适应各自的角色,高度柔性特点增强了网络学习能力,不但可减少网络节点数,而且可减少迭代学习时间。仿真研究中,应用一个900:5A的CT测试所提出的补偿器,测试时考虑了CT原边电流不同直流分量、CT剩磁大小与CT负载特性的影响。仿真结果验证了所提补偿方法的高精度,而且不受CT负载特性、CT剩磁情况及原边电流直流成分的影响。 | 葛宝明 Aníbal T.de Almeida Fernando J.T.E.Ferreira | 2006 | 中国电机工程学报2006,26,16: | 8 |

| 10 | Impacts of fire severity and cattle grazing on early plant dynamics in old-growth Araucaria-Nothofagus forests显示文摘Background: Fire has historically shaped the dynamics of Araucaria araucana-Nothofagus pumilio forests in the Andean region of South America. Nevertheless, human disturbances and stronger drought events have resulted in increased occurrence and severity of wildfires. Regardless of their conservation relevance, the initial response to fire of Araucaria-Nothofagus forests has not been well documented. Through this research we tested the hypothesis that plant composition of Araucaria-Nothofagus forest after fire will initially differ in its recovery depending on fire severity, but over time, plant similarity will increase among areas with different levels of fire severity. The study was carried out in old-growth Araucaria-Nothofagus forests in south-central Chile(38°S) that were burned in 2015. We studied vegetation response to three levels of fire severity(low(LS), moderate(MS) and high(HS) severity), also including an adjacent unburned forest(UN), which were assessed one, two and three years after fire. We also evaluated the impact of cattle on plant recovery after fire. We measured species richness, abundance, plant diversity and origin of all vascular plant species.Results: Species richness and plant abundance responded differently to fire severity. Time-since-fire had a significant effect on plant richness and abundance. Plant composition within LS areas was similar to UN areas, but MS and HS areas were significantly less diverse compared to UN and LS. In absence of other major disturbances, similarity in plant composition tended to increase over time across the different levels of fire severity, becoming more similar to UN. We also found a synergetic effect of cattle and fire on species richness. This interaction promotes the establishment of nonnative species and limits the recovery of native species following fire.Conclusions: Fire severity had a significant impact on the plant community of old-growth Araucaria-Nothofagus forests,especially in areas of high fire severity, where the native tree N. pumilio was completely absent. Nevertheless,plant communities can recover gradually, depending on fire severity, time-since-fire, and the absence of cattle grazing. Management actions should include the exclusion of cattle within fire-affected areas and afforestation with N. pumilio in areas high fire severity due to its unsuccessful recruitment after fire. | Paola Arroyo-Vargas Andres Fuentes-Ramírez Bart Muys Aníbal Pauchard | 2019 | Forest Ecosystems2019,6,4: | 0 |
| 11 | “Regulation of Urban Space and Construction in the Late Ottoman and French Mandate Period”——The Case of Beirut(1840-1940)显示文摘Starting with the declaration of Tanzimat in 1839,the transformation of administration,law,taxation,property rights,education,urban planning and public works were initiated,which caused the regulation of urban and construction regulations as a tool for achieving a modern state.1840,the date of the Health of Towns Report,marks a stage in the growing concern with health.The period between 1840-1940 is a recognisable date in history,with the outbreak of the Great War marking the end of an era.It also marks the date of a major enquiry into building laws and it also sees the virtual completion of the process of the incorporation of the health controls into the building regulations.In this date several regulations were enacted concerning the buildings and the streets and implemented in Beirut.The main goal of this article is to understand the impact of Building Codes on the construction of the late Ottoman Heritage and its architectural typology. | Jad Hammoud Alice Tavares Aníbal Costa | 2018 | Journal of Civil Engineering and Architecture2018,12,9: | 0 |
| 12 | Optical Evaluation of Vibrations in a Concrete Column by the LPD Method显示文摘In this work we present the results of the optical evaluation of vibrations of a conventional concrete column with a metal frame.In a previous work[1]we reported the optical evaluation of a pure concrete column,without a metal framework.In this evaluation we expected to obtain a noticeably different result,but that was not the case,then the obtained results are surprisingly similar.From the LPD evaluations,the first 12 vibration resonances were found,which fit very well with the basic applied theory(the cantilever theory).Using known average values,we estimate the corresponding column effective length,obtaining an average value of 2.5 m.As in the former case of the concrete column,we find a discrepancy with respect to the length value,measurable from the ground(1.75 m),which can be explained again by the fact that the column and its base were built on inconsistent terrain. | Aníbal Valera Miguel Melchor Vicenta Tafur | 2023 | Journal of Civil Engineering and Architecture2023,17,12: | 0 |

| 14 | Acute hepatitis after amiodarone infusion显示文摘Acute hepatitis is a very rare, but potentially fatal, adverse effect of intravenous amiodarone. We present a case of an 88-year-old man with history of ischemic dilated cardiomyopathy and severely depressed left ventricular function that was admitted to our coronary care unit with diagnosis of decompensated heart failure and non-sustained ventricular tachycardia. A few hours after the beginning of intravenous amiodarone he developed an acute hepatitis. There was a completely recovery within the next days after amiodarone withdrawn and other causes of acute hepatitis have been ruled out. This case highlights the need for close monitoring of hepatic function during amiodarone infusion in order to identify any potential hepatotoxicity and prevent a fatal outcome. Oral amiodarone is, apparently, a safe option in these patients. | Paulo Fonseca Adelaide Dias Helena Gonçalves Aníbal Albuquerque Vasco Gama | 2015 | World Journal of Clinical Cases2015,3,10: | 2 |
| 15 | Comparative efficiency analysis of different nonlinear modelling strategies to simulate the biaxial response of RC columns显示文摘The performance of different nonlinear modelling strategies to simulate the response of RC columns subjected to axial load combined with cyclic biaxial horizontal loading is compared. The models studied are classified into two categories according to the nonlinearity distribution assumed in the elements: lumped-plasticity and distributed inelasticity. For this study, results of tests on 24 columns subjected to cyclic uniaxial and biaxial lateral displacements were numerically reproduced. The analyses show that the global envelope response is satisfactorily represented with the three modelling strategies, but significant differences were found in the strength degradation for higher drift demands and energy dissipation. | Hugo Rodrigues Humberto Varum António Arêde Aníbal Costa | 2012 | Earthquake Engineering and Engineering Vibration2012,11,4: | 2 |

| 18 | Resting metabolic rates increase with elevation in a mountain-dwelling lizard显示文摘ndividuals that inhabit broad elevational ranges may experience unique environmental challenges.Because temperature decreases with increased elevation,the ectotherms living at high elevations have to manage limited activity time and high thermoregulatory effort.The resting metabolic rate(RMR)of a postabsorptive animal is related to its total energy requirements as well as many other fitness traits.Mesquite lizards(Sceloporus grammicus)living on La Malinche Volcano,Mexico,inhabit a wide elevational range with some populations apparently thriving above the tree line.We measured the RMR of lizards from different elevations(i.e.,2,600,3,200,and 4,100 m)at four ecologically relevant temperatures(i.e.,15,25,30,and 35°C)and found that RMR of mesquite lizards increased with temperature and body mass.More importantly,lizards from the high-elevation population had mass specific RMR that was higher at all temperatures.While the higher RMRs of high-elevation populations imply higher metabolic costs at a given temperature these lizards were also smaller.Both of these traits may allow these high elevation populations to thrive in the face of the thermal challenges imposed by their environment. | Melissa PLASMAN Amando BAUTISTA Marshall D.McCUE Aníbal H.DÍAZ DE LA VEGA-PÉREZ | 2020 | Integrative Zoology2020,15,5: | 0 |
| 19 | The largest dengue outbreak in Argentina and spatial analyses of dengue cases in relation to a control program in a district with sylvan and urban environments显示文摘Objective: To analyze the largest outbreak of dengue in Argentina in the municipality of Tigre during 2016, through detailed spatial analyses of the occurrence of cases in relation to demographic factors and vector control actions. Methods: Detailed and georreferenced data on dengue cases with laboratory results(NS1 or IgM) were analyzed. The occurrences of imported and autochthonous cases by census tract were modeled using demographic variables(population by age class, proportion of foreigners, proportion with university grade, proportion of males), dwelling variables(number of homes, proportion of dwellings with latrine, number of dwellings, proportion of houses, proportion of flats, proportion of slums) and census tract area as explanatory variables. The probability of occurrence of autochthonous and imported cases was modeled separately. The spatio-temporal occurrence of cases was studied in relation to focal and perifocal control actions(involving education campaigns, removal of Aedes aegypti breeding sites and exhaustive insecticide spraying) to assess the efficiency in stopping autochthonous cases spreading. Results: All autochthonous cases occurred in the urban environment with no sylvan cases. The majority of the imported cases registered came from Paraguay and Northeastern Argentina. The age structure of imported and autochthonous cases did not differ from the age structure of the municipality, while that of the negative cases did.When studied spatially, the occurrence of imported cases by census tract was mildly associated with a higher proportion of foreign population and more people at active age, while occurrence of autochthonous cases was not significantly associated with any of the studied variables.For census tracts with laboratory confirmed results, the models showed higher probability of autochthonous cases related to higher population density and population age structure. The clustering of autochthonous cases was generally mild, with prevailing isolated cases and a weak spread inside the municipality. The biggest outbreak focus was associated with a delay in the focal vector control. Conclusions: Results confirmed the virus pressure coming from neighboring countries and related to population movement by workers. All autochthonous cases occurred in the urban environment with no sylvan cases. The susceptibility of residents to dengue may be similar among age classes and the laboratory tests were performed more frequently in the younger. Autochthonous cases incidence was low and spatio-temporal clustering of cases weak, suggesting that control measures were effective when no delay occurred in their application. | Aníbal E Carbajo Alejandra Rubio María J Viani María R Colombo | 2018 | Asian Pacific Journal of Tropical Medicine2018,11,3: | 0 |
