Abstract: A vibration damper with at least two absorbers, each having at least one spoke spring, enables efficient damping of the frequency response of a crankshaft. The absorbers preferably have different natural frequencies that are adapted to the frequency response of the crankshaft. The absorbers exhibit a frequency response, which is not or only insignificantly dependent on aging of the spoke springs and on the ambient temperature.

Abstract: The present disclosure relates to the treatment of streams derived from construction and/or demolition (C&D) debris, such as C&D fines streams, asphalt shingles, drywall, or wood.

Abstract: A client configured to retrieve a live-stream media content is shown. The client is configured to receive from a live-streaming server a media presentation description (MPD) describing live-stream media content composed of a sequence of segments and an information on a current segment of the sequence of segments. The client is further configured to commence retrieving the live-stream media content from the live-streaming server from a predetermined segment of the sequence of segments onwards, which the client determined based on the information.

Abstract: A streaming media playback device is provided for playing multimedia presentations with segments encoding video data at different quality levels for adaptive streaming through a network from a server, for example based on MPEG DASH. The streaming media playback device selects segments at a given quality level from those available at the server based on an adaptive bitrate setting and an oscillation measure. The adaptive bitrate setting is selected based on network bandwidth conditions. The oscillation measure provides an indication of how often the device switches between segments of different quality levels. The next segment is selected based on the adaptive bitrate setting unless the oscillation measure exceeds a threshold.

Abstract: A video streaming system optimizes the buffering of periods of frames of a video presentation in order to achieve a more constant perceptual quality throughout the entire video presentation. An adaption algorithm determines transmission bitrates to transmit some periods at a lower bitrate that the channel conditions of the channel may allow while transmitting other periods at a higher bitrate. The transmission bitrates are determined based on expected quality metadata signaled in the periods of the bitstream for the current period and following periods in order to optimize the bitrate and the expected perceptual quality of each version of each period over time.
