Gridding global data into a minimally distorted global raster
Map projections necessarily distort the Earth's surface in some fashion as a result of the transformation to a coordinate system. However, different map projection systems can preserve some properties of geospatial data (e.g., area) at the expense of other properties (e.g., distance or azimuth). To produce a minimally distorted global raster, a global raster generator creates a number and variety of projections using as input geospatial data.

Methods and systems for optimal transport of non-linear transformations
Herein is presented a light-weight, high-quality texture synthesis algorithm that generalizes to other applications. We utilize an optimal transport optimization process within a bottleneck layer of an auto-encoder, achieving quality and flexibility on par with expensive back-propagation based neural texture synthesis methods, but at interactive rates. In addition to superior synthesis quality, our statistically motivated approach generalizes better to other special case texture synthesis problems such as Style Transfer, Inverse-Texture Synthesis, Texture Mixing, Multi-Scale Texture Synthesis, Structured Image Hybrids and Texture Painting. We treat the texture synthesis problem as the optimal transport between Probably Density Function of the deep neural activation vectors of the image being synthesized and the exemplar texture. We present a fast algorithm that matches random sliced 1-Dimensional histograms projected from the full N-Dimensional distribution and we propose an extension of this algorithm that reduces dimensionality of neural feature space. |

Using the CV, the orientation of each vertex of the polygon with respect to the test ray is determined. Candidate edges having vertices with opposite orientations with respect to the test ray are identified. Crossing edges are determine by calculating CVs for each candidate edge, and determining orientations of the TP and EP with respect to each candidate edge. A set of crossing edges is determined, where the TP and the EP have opposite orientations with respect to each crossing edge. |

Systems and methods for encoding and decoding data
A method for data retrieval includes receiving a set of probability metrics. A set of probability metrics is received for each one of a plurality of read values, and each probability metric of the set of probability metrics corresponds to a statistical likelihood that the read value is representative of one of a number of symbols. The symbols define a set of allowed transitions between a number of states, and a series of successive allowed transitions between states define allowed paths between the states. The method further includes determining a survival path between the states. The survival path is based on an accumulation of probability metrics corresponding to the statistical likelihood that successive ones of the plurality of read values are representative of successive ones of the symbols defining each transition in the survival path. The method further includes decoding a symbol stream based on the survival path. |

Virtualized block device backing for virtualization containers
Technologies are provided for backing virtualization containers with layered storage volumes stored in remote storage devices. A virtualization container can present a virtual storage volume to a process running in the virtualization container and handle data access requests from the process using a layered storage volume based on one or more read-only snapshots stored in one or more remote storage devices. Changes can be recorded in a read-write layer in one or more of the remote storage devices and associated with the layered storage volume. A new read-only snapshot can be created based on the data in the read-write storage layer and associated with the one or more read-only snapshots on which the layered storage volume is based. A virtualization container can be associated with a new layered storage volume based on the created read-only snapshot and the one or more read-only snapshots on which it is based. |

Technology for governance of data retention and transfer
Policy entries are provided in a policy table for respective geolocations. Audit data entries are generated in an audit table, including a retention period entry generated in response to looking up a retention period entry in the policy table for a first geolocation. In response to copying data to a second geolocation, a retention period audit data entry is generated in the audit table for the data at the second geolocation based on a synchronization policy entry in the policy table. A process causes deletion of the copy at the second geolocation based on an age indicated by the retention period audit data entry for the data at the second geolocation. |

Increasing sizes of buckets of a fingerprint index
In some examples, a system performs data deduplication using a fingerprint index comprising a plurality of buckets, each bucket of the plurality of buckets comprising entries associating fingerprints for data units to storage location indicators of the data units, wherein a storage location indicator of the storage location indicators provides an indication of a storage location of a data unit in persistent storage. For adding a new fingerprint to the fingerprint index, the system detects that a corresponding bucket of the plurality of buckets is full, in response to the detecting, adds space to the corresponding bucket by taking a respective amount of space from a further bucket of the plurality of buckets, and inserts the new fingerprint into the corresponding bucket after increasing the size of the corresponding bucket. |

Memory access
An electronic device comprises a processor operable at a variable processor privilege level and a memory comprising a secure memory area. A hardware module is operable at a variable module privilege level and is arranged to access the memory directly. The secure memory area is accessible by the hardware module only when the module privilege level exceeds a threshold value. The device has a first mode of operation in which said processor privilege level is higher than said threshold value and said module privilege level is lower than said threshold value. A controller is arranged, upon receiving a privilege promotion signal and the device being in the first mode, to move the device to a second mode wherein the module privilege level is higher than said threshold value. |
