34th International Symposium on Remote Sensing of Environment - The GEOSS Era: Towards Operational Environmental Monitoring | Year: 2011

The successful results of a Global Food Security Project supported by the National Geospatial-Intelligence Agency (NGA), the National Aeronautics and Space Administration (NASA), the United States Department of Agriculture (USDA) and other government entities led to the development of a pilot project where these data experts are coordinating and sharing their expertise with the private sector-to perform project work which requires extremely difficult computational analytics with high volume satellite imagery such as, NOAA-TRMM, NASA-MODIS, NCEP, Air Force-AFWA, AWIFS, SPOT-Veg provided by the USDA and PET datasets which consist of raster and vector data (100's of gigabytes per country). The data have been placed in a secure, interoperable cloud at the Rocky Mountain Supercomputing Centers, Inc. running Microsoft HPC Server 2008 and SQL Server Enterprise with the latest edition of ESRI ArcGIS. The scalable solution is being used to complete high-fidelity analytics: Time series analysis, change detection, correlation analysis for geoprocessing and geostatistics. The outcomes of the project can change earth observation monitoring forever by allowing this same processing for the entire globe, using all the data sets in an interoperable, real-time environment, whether we are looking at Global Food Security issues, Water Resource Management, Provincial Reconstruction or any other application requiring real-time management of multiple input variables these predictive models will save precious resources - time and money - and most importantly provide enormous societal benefit.

In this paper, direct method is applied for calculating the hyperbolic flow past a sphere. The surface of the body is discretised into boundary elements on which the velocity distribution is found. The comparison of computed and exact results is also made. © 2012. Zhengzhou University, Marsland Press.

BMC Cancer | Year: 2016

Background: In the context of early detection of head and neck cancers (HNC), the aim of this study was to describe how people sought medical consultation during the year prior to diagnosis and the impact on the stage of the cancer. Methods: Patients over 20 years old with a diagnosis of HNC in 2010 were included from four French cancer registries. The medical data were matched with data regarding uptake of healthcare issued from French National Health Insurance General Regime. Results: In 86.0 % of cases, patients had consulted a general practitioner (GP) and 21.1 % a dentist. Consulting a GP at least once during the year preceding diagnosis was unrelated to Charlson index, age, sex, département, quintile of deprivation of place of residence. Patients from the 'quite privileged', 'quite underprivileged' and 'underprivileged' quintiles consulted a dentist more frequently than those from the 'very underprivileged' quintile (p = 0.007). The stage was less advanced for patients who had consulted a GP (OR = 0.42 [0.18-0.99]) - with a dose-response effect. Conclusions: In view of the frequency of consultations, the existence of a significant association between consultations and a localised stage at diagnosis and the absence of a socio-economic association, early detection of HNC by GPs would seem to be the most appropriate way. © 2016 The Author(s).

Physical and Occupational Therapy in Pediatrics | Year: 2010

The purpose of this study was to determine the effects of prolonged standing on gait characteristics in children with spastic cerebral palsy. Six children with spastic cerebral palsy participated in this study with an average age of 6.5 years (SD 2.5, range 4.09.8 years). A reverse baseline design (A-B-A) was used over a 9-week period. During phase A, the children received their usual physical therapy treatment. During phase B, children received the prolonged standing program three times per week, in addition to their usual physical therapy treatment. During phase A2, children received their usual physical therapy treatment. Gait analysis and clinical assessment of spasticity were performed before and after each phase. Analysis of variance (ANOVA) for repeated measurements was used to test for changes in gait measures across the four measurement sessions. Friedman's was used to test for changes in muscle tone (Modified Ashworth Scale) across the four measurement sessions. Stride length (p <.001), gait speed (p <.001), stride time (p <.001), stance phase time (p <.001), double support time (p <.003), muscle tone (p <.02), and peak dorsiflexion angle during midstance (p <.004) improved significantly following the intervention phase. The results of this study demonstrate that the gait pattern of children with cerebral palsy classified as level II or III on the Gross Motor Functional Classification System (GMFCS) improved by a prolonged standing program. However, these improvements were not maintained at 3 weeks. Further research is necessary with larger sample sizes to replicate these findings and determine specific "dosing" for standing programs to create long-lasting functional effects on gait.
