Abstract: An example computing system is configured to: (i) apply a first access permission setting that defines whether a party can access a data object associated with a multi-phase construction project during a first phase of the multi-phase construction project; (ii) determine that the multi-phase construction project has transitioned from the first phase to a second phase; and (iii) based at least on the determination that the multi-phase construction project has transitioned from the first phase to the second phase, apply a second access permission setting that defines whether the party can access the data object associated with the multi-phase construction project during the second phase of the multi-phase construction project, where the second access permission setting differs from the first access permission setting.

Abstract: A method and apparatus are provided to map the shape or thickness of a surface. Thickness estimates across a distance are received, and Fourier analysis is performed to generate Fourier amplitude coefficients and phase values for a number of frequency components. Linear discriminant functions are used to characterize the resulting shape as normal or not. Discriminant functions are provided that aid in the diagnosis of glaucoma when the thickness measured is the retinal nerve fiber layer thickness.

Abstract: A system for the in vivo detection of the effects of AD in the interior of an eye. A scanning polarimeter, including a residual retardance canceling system and an improved anterior segment retardance compensator, produces an optical analysis signal representing the birefringence of the retinal nerve fiber layer (RNFL) structures of the eye. The birefringence data is more accurate because of compensation for anterior segment birefringence and residual birefringence of optical components, such as, for example, the beam splitters, lenses, scanners and retarders. An electrical analysis signal representing a large (20 by 40 degrees) retardance map is produced and evaluated by an artificial neural network to produce an analysis classification signal representing the contribution of Alzheimer's disease to the birefringence of the retinal layer corresponding to the relationship of the electrical analysis signal to an analysis signal database.
