This paper analyses the pure time-series properties of doctors’ fees in Ireland to assess whether a structural change in the series is observed at the time of the change in reimbursement in 1989. Such a break would be consistent with doctors responding to the reimbursement change in a manner predicted by supplier-induced-demand behaviour and would provide indirect evidence that such inducement ...
Linear models where the response is a function and the predictors are vectors are useful in analyzing data from designed experiments and other situations with functional observations. Residual analysis and diagnostics are considered for such models. Studentized residuals are defined and their properties are studied. Chi-square quantile-quantile plots are proposed to check the assumption of Gaus...
background: cesarean section is a surgery to deliver a baby and remove the placenta and membranes through an incision made on the mother's abdomen and uterus. while the rate of cesarean section is 10-30% of all deliveries in the world, it is 50-65% in iran. the aim of this study was to identify factors leading to cesarean section in bam, iran. methods: in this cross-sectional study, 200 mothers...
This paper summarizes the results of experimental observations and measurements of beam-beam interactions in DAΦNE, the Frascati Phi-factory. The achieved results are reported with analysis of present limitations in both single and multibunch operation modes and compared with numerical simulations.
The Sensor Web provides access to observations and measurements through standardized interfaces defined by the Open Geospatial Consortium’s Sensor Web Enablement (SWE) initiative. While clients compliant to these standards have access to the generated sensor data, it remains partially hidden from other knowledge infrastructures building on higher-level W3C standards. To overcome this problem, i...
