Abstract: A system and method for generating 3D-aware reconstructions of a static or dynamic scene by using a neural network to encode captured images of the scene into a compact spatio-temporal polynomial latent space scene model. Image frames of a scene are received. Each image frame is associated with camera extrinsics including a three-dimensional (3D) camera location and a camera direction. A neural network is trained using the image frames (e.g., video frames) and the camera extrinsics to encode the frames as models of the scene in a spatio-temporal polynomial latent space. The models of the scene are transmitted to a viewing device including a latent model decoder. The latent model decoder is configured to decode the models to generate imagery corresponding to novel 3D views of the scene.

Abstract: For determining whether oil waste at a field testing site is exempt from selected naturally occurring radioactive material (NORM) waste regulations, a measurement apparatus including a detection module that determine radioactivity counts per minute for an oil waste sample is utilized. The measurement apparatus includes an analysis module that uses a first nonlinear transfer function to determine a mass for the oil waste based on a volume of solids determined via BS&W testing. The analysis module uses a second nonlinear transfer function to determine a maximum radioactivity level for the sample which is then normalized to picoCuries/g. The normalized maximum radioactivity level per gram is compared to a NORM exemption level for a selected region and communicated to entities at the field-testing site and optionally to other entities. A system and a method perform the functions of the measurement apparatus.

Abstract: A wireless network includes nodes configured to implement an improved parent and path selection process to efficiently and reliably manage energy consumption of a battery powered device node. When a given node selects a path, the node transmits requests to multiple potential parent nodes. Each potential parent node transmits a metric that is indicative of the remaining battery life of the nodes in the path that includes the respective potential parent node. The given node then selects a parent node, and corresponding path, based on the metrics. More specifically, the given node selects a path, where at least one node on the selected path is less likely to prematurely exhaust the remaining battery life of the node, relative to the nodes in the other potential paths. As a result, the given node selects a path that optimizes battery consumption of the various battery powered nodes in the wireless network.
