Abstract: Example methods and systems for blockchain-based licensing as a service are described. In one example, a computer system may receive a first request to obtain a first license associated with a first product from a first client system. In response, the computer system may (a) select a first blockchain from multiple blockchains, and (b) generate and store a first non-fungible token (NFT) on the first blockchain to issue the first license. Further, the computer system may receive a second request to obtain a second license associated with the first product or a second product from a second client system. In response, the computer system may (a) select a second blockchain from multiple blockchains, and (b) generate and store a second NFT on the second blockchain to issue the second license.

Abstract: Systems and methods for thermal transport in space for cryogenic propellant storage tank chilldown are described. In order to maximize the storage tank chilldown thermal efficiency for the least amount of required cryogen consumption, the embodiments relate to quenching heat transfer concepts that can include the combination of cryogenic spray quenching cooling, thermal insulator thin-film coating on the tank inner surface, and spray flow pulsing. The boiling heat transfer physics that supports the concepts are described. The completed flight experiments successfully demonstrated the feasibility of the concepts and discovered that spray cooling can be an efficient cooling method for the tank chilldown in microgravity. In microgravity, the data shows that the chilldown thermal efficiency can reach 30% with a thermal insulator coating alone. Further thermal efficiencies can be made up to 50% with flow pulsing.

Abstract: The described technology is generally directed towards a transport protocol for latency sensitive applications. The disclosed transport protocol is “semi-reliable” in that it allows for specification of an importance of data being transmitted, thereby allowing important data to be sent reliably, while other data can be dropped if necessary, e.g., under bad network conditions. A deadline can be specified for such other data, and if the other data cannot be sent prior to the deadline, it can be dropped. Furthermore, the disclosed transport protocol can allow for early discovery of network jitter. A client device can send regular acknowledgments which identify most recently received data packets as well as a number of “heartbeat transmissions” received at the client device. A server device can use the acknowledgments to discover and respond to jitter.

Abstract: A network processing system obtains a viewport of a client device for volumetric video and a two-dimensional (2D) subframe of a frame of volumetric video is obtained associated with the viewport. Viewports may be obtained from the client device or be predicted. 2D subframes and reduced resolution versions of frames can be transmitted to the client device. A client device may request volumetric video from the network processing system and provides a viewport to the network processing system. The client device may obtain from the network processing system reduced resolution versions of volumetric video frames and 2D subframes in accordance with the viewport. The client device may determine whether a current viewport matches the viewport associated with the obtained 2D subframe and provides a display based on either that subframe (upon a match) or a 2D perspective of the reduced resolution frame associated with the current viewport (if no match).
