The Spatial Resolution of Epidemic Peaks
The emergence of novel respiratory pathogens can challenge the capacity of key health care resources, such as intensive care units, that are constrained to serve only specific geographical populations. An ability to predict the magnitude and timing of peak incidence at the scale of a single large population would help to accurately assess the value of interventions designed to reduce that peak....
متن کاملThe effect of focal spot size on the spatial resolution of variable resolution X-ray CT scanner
Background: A variable resolution X-ray (VRX) CT scanner provides a great increase in the spatial resolution. In VRX CT scanners, the spatial resolution of the system and its field of view (FOV) can be changed according to the object size. One of the main factors that limit the spatial resolution of VRX CT scanner is the effect of the X-ray focal spot. Materials and Methods: A theoreti...
متن کاملInvestigation of the Spatial Resolution and Field of View with Change of Magnification in VRX CT
Introduction: Variable resolution x-ray (VRX) CT is a new type of CT that can image objects at various spatial resolutions. In a VRX CT scanner, the spatial resolution increases at the cost of reduction in the field of view (FOV). An important factor that limits the spatial resolution of the VRX CT is the effect of focal spot size. Also, the optimum magnification is different at each incident a...
متن کاملSpatial General Epidemic Model
The general consideration in Spatial General Epidemic Model is controlling the propagation of the disease starting from an infected individual. By a suitable control process, this epidemic can be rooted out. Here, we suggest the control process using the percolation probability to be attached with the formation of edges having the suitable probabilities, giving the random graphs which will expl...
