| 1 | Intelligent Islanding Detection of Multi-distributed Generation Using Artificial Neural Network Based on Intrinsic Mode Function Feature显示文摘The integration of distributed energy resources(DERs) into distribution networks is becoming increasingly important, as it supports the continued adoption of renewable power generation, combined heat and power plants, and storage systems. Nevertheless, inadvertent islanding operation is one of the major protection issues in distribution networks connected to DERs. This study proposes an intelligent islanding detection method(IIDM) using an intrinsic mode function(IMF)feature-based grey wolf optimized artificial neural network(GWO-ANN). In the proposed IIDM, the modal voltage signal is pre-processed by variational mode decomposition followed by Hilbert transform on each IMF to derive highly involved features. Then, the energy and standard deviation of IMFs are employed to train/test the GWO-ANN model for identifying the islanding operations from other non-islanding events. To evaluate the performance of the proposed IIDM, various islanding and non-islanding conditions such as faults, voltage sag, linear and nonlinear load and switching, are considered as the training and testing datasets. Moreover, the proposed IIDM is evaluated under noise conditions for the measured voltage signal. The simulation results demonstrate that the proposed IIDM is capable of differentiating between islanding and non-islanding events without any sensitivity under noise conditions in the test signal. | Samuel Admasie Syed Basit Ali Bukhari Teke Gush Raza Haider Chul Hwan Kim | 2020 | Journal of Modern Power Systems and Clean Energy2020，8，3： | 2 |

| 6 | Prevalence of diarrhoea and risk factors among children under five years old in Mbour,Senegal:a cross-sectional study显示文摘Background:Diarrhoeal diseases remain an important cause of mortality and morbidity among children,particularly in low-and middle-income countries.In Senegal,diarrhoea is responsible for 15%of all deaths in children under the age of five and is the third leading cause of childhood deaths.For targeted planning and implementation of prevention strategies,a context-specific understanding of the determinants of diarrhoeal diseases is needed.The aim of this study was to identify risk factors of diarrhoeal diseases in children under the age of five in Mbour,Senegal.Methods:Between February and March 2014,a cross-sectional survey was conducted in four zones of Mbour to estimate the burden of diarrhoeal diseases(i.e.diarrhoea episodes in the 2 weeks preceding the survey)and associated risk factors.The zones covered urban central,peri-central,north peripheral and south peripheral areas.Overall,596 households were surveyed by a questionnaire,yielding information on sociodemographic,environmental and hygiene behavioural factors.Univariable and multivariable logistic regression analyses were used to identify risk factors associated with the occurrence of diarrhoea.Results:The reported prevalence of diarrhoea among children under the age of five during the 2 weeks preceding the survey was 26%.Without adjustment,the highest diarrhoea prevalence rates were observed in the peri-central(44.8%)and urban central zones(36.3%).Multivariable regression revealed significant associations between diarrhoeal diseases and unemployment of mothers(adjusted odds ratio[aOR]=1.62,95%confidence interval[CI]:1.18-2.23),use of open bags for storing household waste(aOR=1.75,95%CI:1.00-3.02),evacuation of household waste in public streets(aOR=2.07,95%CI:1.20-3.55),no treatment of stored drinking water(aOR=1.69,95%CI:1.11-2.56)and use of shared toilets(aOR=1.69,95%CI:1.11-2.56).Conclusion:We found a high prevalence of diarrhoea in children under the age of five in Mbour,with the highest prevalence occurring in the central and peri-central areas.These findings underscore the need for public health interventions to alleviate the burden of diarrhoea among vulnerable groups.Promotion of solid waste disposal and reduction of wastewater exposure should be implemented without delay. | Sokhna Thiam Aminata N.Diene Samuel Fuhrimann Mirko S.Winkler Ibrahima Sy Jacques A.Ndione Christian Schindler Penelope Vounatsou Jurg Utzinger Ousmane Faye Gueladio Cisse | 2017 | Infectious Diseases of Poverty2017，6，1： | 1 |
