Embodiments are directed to target bitrate prediction methods in which one or more objective metrics may serve as inputs into a model that predicts a mean opinion score (MOS), a measure of perceptual quality, as a function of metric values. The model may be derived by generating training data through conducting subjective tests on a set of video encodings, obtaining MOS data from the subjective tests, and correlating the MOS data with metric measurements on the training data. The MOS predictions may be extended to predict the target (encoding) bitrate that achieves a desired MOS value. The target bitrate prediction methods may be applied to segments of a video. The methods may be made computationally faster by applying temporal subsampling. The methods may also be extended for adaptive bitrate (ABR) applications by applying scaling factors to predicted bitrates at one frame size to determine predicted bitrates at different frame sizes. A dynamic scaling algorithm may be used to determine predicted bitrates at the different frame sizes. |

The virtualization engine expropriates, from the network element, processes for communicating in the NMP and can, thereby, reduce the computational resources used by the network element for communicating in the NMP. The virtualization engine generates a NMP response to the NMP request. The virtualization engine transmits a different message containing the NMP response to the network element using SFC by inserting service plane protocol data into the message (e.g., an impregnated response). |

Continuous quantum sensor
Atom-scale particles, e.g., neutral and charged atoms and molecules, are pre-cooled, e.g., using magneto-optical traps (MOTs), to below 100 μK to yield cold particles. The cold particles are transported to an atom-chip cell which cools the cold particles to below 1 μK; these particles are stored in a reservoir within the atom-chip cell so that they are readily available to replenish a sensor population of particles in quantum superposition. A baffle is disposed between the MOTs and the atom-chip cell to prevent near-resonant light leaking from the MOTs from entering the atom-chip cell (and exciting the ultra-cold particles in the reservoir). The transporting from the MOTs to the atom-chip cell is effected by moving optical fringes of optical lattices and guiding the cold particles attached to the fringes along a meandering path through the baffle and into the atom-chip cell. |

Occlusion using pre-generated 3D models for augmented reality
To prevent virtual content from occluding physical objects in an augmented reality (AR) system, the embodiments herein describe generating a pass-through texture using a pre-generated model of a physical object. In one embodiment, the AR system determines the location of the physical object as well as its orientation. With this information, the system rotates and re-sizes the pre-generated model of the object to match its location and orientation in the real-world. The system then generates the pass-through texture from the pre-generated model and inserts the texture into the virtual content. When the virtual content is displayed, the pass-through texture permits light from the real-world view to pass through substantially unaffected by the virtual content. In this manner, the physical object (which aligns with the location of the pass-through texture in the virtual content) can be seen by the user—i.e., is not occluded by the virtual content. |
