Abstract: One embodiment of the invention sets forth a mechanism for recommending digital items to a user. Each digital item in a set of digital items is scored based on user preferences and other metrics. The digital items are ordered based on scores. The digital items are then evaluated in order of respective rank to determine a subset of digital items that re recommended to the user. The evaluation process is based on different evaluation criteria as well as the presentation style of the recommended digital items.

Abstract: One embodiment of the present invention sets forth a technique for recommending digital content to a user of a digital content application based on continually learned patterns of behavior. Based on metrics collected from a current session of the digital content application, properties associated with one or more users interacting with the application are inferred. The inferred properties are matched against previously defined patterns of behavior to identify digital content that could be presented to the one or more users for optional selection.

From the warm side, the compressed hydrogen and, from the cold side, liquefied hydrogen can be supplied from the storage tank for liquefied hydrogen. A relief valve is located in the field region of the at least one magnet coil.

Abstract: Genres and associated digital items are recommended to a user based on the interests of the user. Genres that are of interest to the user are determined based on user preferences gathered implicitly or explicitly. The genres are then scored and sorted based on different scoring and sorting techniques. A subset of the scored and sorted genres is then selected for recommending to the user.

Abstract: A heat transfer unit for an internal combustion engine includes a first channel with an inlet and an outlet. The first channel is configured to have a fluid to be cooled flow therethrough. The second channel is configured to have a cooling fluid flow therethrough. A partition wall(s) is disposed to separate the first channel from the second channel. Ribs extend from partition wall(s) into the first channel and are disposed in a principal flow direction of the fluid to be cooled. The second channel comprises a first section and a second section in the principal flow direction. The ribs of the first section have a first cross section in a first flow-off portion that is constant in the principal flow direction. The ribs of the second section have a second cross section in a second flow-off portion that widens in the principal flow direction.

Abstract: A device-implemented network with domains each having nodes, the nodes of each of the domains sharing network information with one another according to an intra-domain communication policy. An inter-domain protocol is configured to control communication between at least one of the nodes of one of the domains and at least one of the nodes of a different one of the domains. A broker is configured to be communicatively coupled to the nodes and configured to control communication according to the inter-domain protocol and to which all of the nodes of each of the plurality of domains are configured to send the network information.

Abstract: By using a mechanical planetary differential as a multiple input, single output device, the speed of the single output can be controlled by the speed of one of the inputs while the other input may run at a constant speed.

Abstract: A method and apparatus for determining an effective cross-sectional area of a borehole including one or more sources for generating tube or Stoneley waves in the borehole; receivers for measuring amplitudes of the waves; and means to relate said measured amplitudes to said effective cross-sectional area or related parameters.

Abstract: Methods, networks and nodes for dynamically establishing encrypted communications between a first node having a first identification and a first private key and a second node having a second identification and a second private key. A first signal comprising information indicative of the first identification of the first node is transmitted, then, upon receipt of the first signal by the second node, a second signal comprising information indicative of the second identification of the second node and a first portion of a symmetric key is transmitted, then, upon receipt of the second signal by the first node, a third signal comprising a second portion of the symmetric key is transmitted.
