| 1 | Simulation Tools for a Fiber-Optic Based Structural Health Monitoring System显示文摘Probability of detection(POD)graphics allow for a change from qualitative to quantitative assessment for every damage detection system,and as such it is a main request for conventional non-destructive testing(NDT)techniques.Its availability can greatly help towards the industrialization of the corresponding Structural health monitoring(SHM)system.But having in mind that for SHM systems the sensors are at fixed positions,and the location of a potential damage would change its detectability.Consequently robust simulation tools are required to obtain the model assisted probability of detection(MAPOD)which is needed to validate the SHM system.This tool may also help for the optimization of the sensor distribution,and finally will allow a probabilistic risk management.INDEUS,simulation of ultrasonic waves SHM system,was a main milestone in this direction.This article deals with the simulation tools for a strain based SHM system,using fiber optic sensors(FOS).FOS are essentially strain/temperature sensors,either with multi-point or with distributed sensing.The simulation tool includes the finite element model(FEM)for the original and damaged structure,and algorithms to compare the strain data at the pre-established sensors locations,and from this comparison to extract information about damage occurrence and location.The study has been applied to the structure of an all-composite unmanned aircraft vehicle(UAV)now under construction,designed at Universidad Politecnica de Madrid for the inspection of electrical utilities networks.Distributed sensing optical fibers were internally bonded at the fuselage and wing.Routine inspection is planned to be done with the aircraft at the test bench by imposing known loads.From the acquired strain data,damage occurrence may be calculated as slight deviations from the baselines.This is a fast inspection procedure without requiring trained specialists,and it would allow for detection of hidden damages.Simulation indicates that stringer partial debondings are detected before they become critical,while small delaminations as those produced by barely visible impact damages would require a prohibited number of sensing lines.These simulation tools may easily be applied to any other complex structure,just by changing the FEM models.From these results it is shown how a fiber optic based SHM system may be used as a reliable damage detection procedure. | Alfredo Güemes Antonio Fernandez-Lopez Jaime García-Ramírez Maria Eugenia Reyes-Perez Flor Criado Zurita | 2018 | Transactions of Nanjing University of Aeronautics and Astronautics2018，35，2： | 2 |
| 2 | Central line-associated bloodstream infection among children with biliary atresia listed for liver transplantation显示文摘BACKGROUND Pre-transplant nutrition is a key driver of outcomes following liver transplantation in children.Patients with biliary atresia(BA) may have difficulty achieving satisfactory weight gain with enteral nutrition alone,and parenteral nutrition(PN) may be indicated.While PN has been shown to improve anthropometric parameters of children with BA listed for liver transplantation,less is known about the risks,particularly infectious,associated with this therapy among this specific group of patients.AIM To describe the incidence,microbiology,and risk factors of central line-associated bloodstream infection(CLABSI) among children with BA listed for liver transplantation.METHODS Retrospective review of children aged ≤ 2-years of age with BA who were listed for primary liver transplantation at Texas Children's Hospital from 2008 through2015(n = 96).Patients with a central line for administration of PN(n = 63) were identified and details of each CLABSI event were abstracted.We compared the group of patients who experienced CLABSI to the group who did not,to determine whether demographic,clinical,or laboratory factors correlated with development of CLABSI.RESULTS Nineteen of 63 patients(30%,95%CI:19,43) experienced 29 episodes of CLABSI during 4800 line days(6.04 CLABSI per 1000 line days).CLABSI was predominantly associated with Gram-negative organisms(14/29 episodes,48%)including Klebsiella spp.,Enterobacter spp.,and Escherichia coli.The sole polymicrobial infection grew Enterobacter cloacae and Klebsiella pneumoniae.Grampositive organisms(all Staphylococcus spp.) and fungus(all Candida spp.)comprised 9/29(31%) and 6/29(21%) episodes,respectively.No demographic,clinical,or laboratory factors were significantly associated with an increased risk for the first CLABSI event in Cox proportional hazards regression analysis CONCLUSION There is substantial risk for CLABSI among children with BA listed for liver transplantation.No clinical,demographic,or laboratory factor we tested emerged as an independent predictor of CLABSI.While our data did not show an impact of CLABSI on the short-term clinical outcome,it would seem prudent to implement CLABSI reduction strategies in this population to the extent that each CLABSI event represents potentially preventable hospitalization,unnecessary healthcare dollar expenditures,and may exact an opportunity cost,in terms of missed allograft offers. | Nicole D Triggs Stacey Beer Sonam Mokha Kat Hosek Danielle Guffey Charles G Minard Flor M Munoz Ryan W Himes | 2019 | World Journal of Hepatology2019，11，2： | 2 |
