Abstract: A method of determining absolute permeability in carbonates without upscaling computations includes performing a nuclear magnetic resonance (NMR) analysis and a mercury-injection capillary-pressure (MICP) analysis on at least three samples from carbonate rock of a set of representative regions to determine an experimental permeability, where each of the representative regions have properties related to the porosity and pore-throat size of the carbonate rock. A series of low resolution X-ray scans and a series of high resolution X-ray scans are performed on the same three samples of the carbonate rock of the set of representative regions. Permeability simulations are performed on the same three samples of the carbonate rock of the set of representative regions to determine a computed permeability. The experimental permeability and the computed permeability are then compared to provide computationally manageable and reasonable estimates of the absolute permeability of the carbonate rock.

Abstract: Operations of computing devices are managed using one or more deep neural networks (DNNs), which may receive, as DNN inputs, data from sensors, instructions executed by processors, and/or outputs of other DNNs. One or more DNNs, which may be generative, can be applied to the DNN inputs to generate DNN outputs based on relationships between DNN inputs. The DNNs may include DNN parameters learned using one or more computing workloads. The DNN outputs may be, for example, control signals for managing operations of computing devices, predictions for use in generating control signals, warnings indicating an acceptable state is predicted, and/or inputs to one or more neural networks. The signals enhance performance, efficiency, and/or security of one or more of the computing devices. DNNs can be dynamically trained to personalize operations by updating DNN weights or other parameters.

Abstract: A communication device, method and computer program product enable multiple transceiver communication in a communication device having a configurable housing. A pivot mechanism is connected between first and second housing portions for relative movement of a housing assembly between open and closed positions. The closed position aligns four antenna positions in the first housing portion adjacent to one of four antenna positions in the second housing portion to present four pairings of adjacent antenna positions. Four antennas are positioned within the first housing portion or the second housing portion at a different one of the four pairings of adjacent antenna positions. A radio frequency (RF) front end is communicatively coupled to the four antennas and has two or more transceivers that utilize the four antennas to communicate without antenna-to-antenna signal cancellation in RF low band while the housing assembly is in either of the open position and the closed position.
