Video coding using separate learning and filtering pathways
Separate pathways for filtering and for machine learning are introduced within a video coder. A first pathway filters a first copy of a reconstructed frame to produce a filtered frame, which is included in an output video stream for display at a user device.

Controlling image display via real-time compression in peripheral image regions
Techniques are described for controlling image display via compression of image data in some image regions while performing less or no compression in other (e.g., peripheral view) regions, with color-specific compression preserving chromatic aberration compensation. Such techniques may be used with display panel(s) of a head-mounted display device used for virtual reality display. A primary region of an image at which to encode and display data at a highest resolution level may be determined by tracking a gaze of a user, while other secondary regions may be selected to be surrounding or other outside the primary region. In the secondary regions, image data for a first (e.g., green) color channel may be encoded at a first compression level for a first resolution level lower higher than for other second color channels, and HDR data may be compressed at higher compression levels than the color-specific data. |

Efficient multi-view coding using depth-map estimate for a dependent view
The usual coding order according to which the reference view is coded prior to the dependent view, and within each view, a depth map is coded subsequent to the respective picture, may be maintained and does lead to a sacrifice of efficiency in performing inter-view redundancy removal by, for example, predicting motion data of the current picture of the dependent view from motion data of the current picture of the reference view. Rather, a depth map estimate of the current picture of the dependent view is obtained by warping the depth map of the current picture of the reference view into the dependent view, thereby enabling various methods of inter-view redundancy reduction more efficiently by bridging the gap between the views. According to another aspect, the following discovery is exploited: the overhead associated with an enlarged list of motion predictor candidates for a block of a picture of a dependent view is comparatively low compared to a gain in motion vector prediction quality resulting from an adding of a motion vector candidate which is determined from an, in disparity-compensated sense, co-located block of a reference view. |

Hardware-based packet forwarding for the transport layer
This document describes, among other things, improved methods, systems, and apparatus for relaying packets on computer networks. Preferably, the relay function is accelerated at a host by implementing selected forwarding functions in hardware, such as the host's network interface card, while upper software layers at the host retain at least some access to the packet flow to handle more complex operations and/or monitoring. In a so-called “split TCP” arrangement, for example, a relay host terminates a first TCP connection from a given host and forwards packets on that connection to another given host on a second TCP connection. The relay host has a TCP forwarding table implemented at the device level, configurable by a relay management application running in the kernel or user-space. Special forwarding table modes may be used to enable full-TCP protocol support while also taking advantage of hardware acceleration. |

Decentralized, resource aware load distribution in a distributed system
Distributed Systems are becoming very large and are being served by 10s of 1000s of individual machines. Among heterogeneous nodes, one node's capabilities can vary widely from that of others in the same cluster, for example, in a cluster of storage servers. Each of the clients/writers may retrieve, periodically, from all the servers, important metrics such as free disk space capacity, average disk IO utilization over the last N minutes, etc. We call these client to nodes (servers) messages as “periodic metrics query.” Using received metrics, clients dynamically assign weights to each of the servers as an indication of their current capabilities. Server metrics and or weights are distributed across the clients, and each client may make independent placement decisions based on their view of the cluster. Because clients are using substantially the same information for making decisions on placement, the result is improved balance across the servers. |

Authentication system
A server performs authentication, in response to an authentication request from a client PC and issues a token, when the user of an application is permitted.

Bipolar plate for fuel cell having controlled structure of carbon materials and method of manufacturing the same
This invention relates to a bipolar plate for a fuel cell having a controlled structure of carbon materials and a method of manufacturing the same, the method including obtaining a masterbatch by mixing a first carbon material powder having a size ranging from 0.1 to 200 μm with a polymer resin, forming a masterbatch powder by crushing the masterbatch, preparing a conductive composition by mixing the masterbatch powder with a second carbon material powder having a size ranging from 300 μm to 1 mm, and manufacturing a bipolar plate by subjecting the conductive composition to compression molding. Thereby, carbon materials in a powder phase having different sizes can be uniformly dispersed via a masterbatch to thus shorten a conductive path, thereby decreasing electrical resistivity, and furthermore, dispersion in the polymer resin can be improved, thereby increasing flexural strength. |
