Abstract: A computer-implemented method includes: obtaining, by a computing device, data items from data sources; classifying, by the computing device, the data items into categories using a first machine learning (ML) model; generating, by the computing device, a risk score of a first data center based on the classified data items and using a second machine learning (ML) model; determining, by the computing device, the risk score of the first data center exceeds a threshold; and in response to the determining the risk score of the first data center exceeds the threshold, initiating, by the computing device, a migration of the first data center to a second data center.

Abstract: The subject matter described herein includes methods, systems, and computer readable media for controlling orientation of a photovoltaic collection system to track apparent movement of the sun. According to one aspect, a method for controlling orientation of a photovoltaic collection system to track apparent movement of the sun using a photovoltaic-collection-system-derived tracking algorithm is provided. The method includes determining an initial orientation of a photovoltaic collection system. The method further includes automatically deriving, using output from the photovoltaic collection system as it tracks apparent movement of the sun across the sky caused by spinning of the earth on its axis and its orbit around the sun, a tracking algorithm for controlling orientation of the photovoltaic collection system to track the apparent movement of the sun.

Abstract: Methods, systems, and computer program products for processing three-dimensional image data to render an image from a viewpoint within or beyond an occluding region of the image data are disclosed. According to one method, a set of three-dimensional image data is accessed. The image data includes image data for a surface of interest and image data for a region occluding the surface of interest from a desired viewpoint. The viewpoint may be within or beyond the occluding region. A plurality of rays is cast from the viewpoint to the surface. Along each ray, an occlusion determination is made independent from a volume rendering transfer function definition to render voxels within the occluding region as transparent or partially transparent. The volume rendering transfer function is applied along a portion of each ray outside of the occluding region to render voxels defining surface of interest as visible. The voxels that define the surface are displayed as visible.

Abstract: The invention relates to flexible occlusion rendering, including receiving a first set of three dimensional image data including image data for a surface of interest and image data for a region occluding the surface of interest from a desired viewpoint. The purpose of this invention is to improve occlusion rendering via imaging by locating the occluding surface of the incoming three-dimensional data and, and modifying the characteristics of this data, to show the surface that is being occluded so that the image includes viewing through the occlusion to the surface of interest.

Abstract: Disclosed is a lightweight reflecting system for the concentration of solar radiation in which the reflecting optic is approximately sinusoidal in cross section and is maintained in this shape by minimal contact with a support frame. The reflector can be a flexible rectangular sheet deformed into a generally sinusoidal trough by compression between fixed or adjustable end supports. The sinusoid can be adjusted to be less than half a cycle by torsion applied to each end of the flexible sheet. A reflective film, polished metal, or similar material on the reflector surface can concentrate sunlight along a diffuse band rather than a sharp line, providing improved concentration levels for photovoltaic cells. The reflectors and their support frames can be mounted singly or severally on a tracking device that maximizes instantaneous power output by orienting the collectors toward the sun.
