[Problem] In order to improve the likelihood of being able to continue delivery even during degradation of communication quality and improve the efficiency of use of the capability of a transmission path, even with hierarchical encoding having a small number of hierarchies, the present invention comprises: measuring the communication quality of the transmission path with a data receiving device; determining a hierarchical structure of hierarchical data on the basis of the results of measuring the communication quality; generating the hierarchical data of the hierarchical structure by hierarchical encoding of input data; and delivering delivery data of at least some hierarchies of the hierarchical data to the data receiving device.

Methods and apparatus for efficient scaling of fabric architectures such as those based on PCIe technology, including up to very large fabrics and numbers of hosts/devices for use in ultra-high performance applications such as for example data centers and computing clusters. In one aspect, methods and apparatus for using Non-Transparent Bridge (NTB) technology to export Message Signaled Interrupts (MSIs) to external hosts are described. In a further aspect, an IO Virtual Address (IOVA) space is created is used as a method of sharing an address space between hosts, including across the foregoing NTB(s). Additionally, a Fabric Manager (FM) entity is disclosed and utilized for programming e.g., PCIe switch hardware to effect a desired host/fabric configuration.

A recovery support apparatus includes an index value calculation means which calculates a predetermined index value with respect to a recovery work sequence on the basis of the recovery work sequence indicating a work procedure for recovery from an abnormality that has occurred in an apparatus group constituting a communication network, and an output means which outputs the index value calculated by the index value calculation means to a predetermined output destination.

To optimize content of a webpage in a manner that depends on whether or not a user has linked accounts to each other. The solving means is an information processing apparatus including a storage unit, a communication unit, and a control unit. The storage unit stores information regarding a first account of each of a plurality of users and first content and second content to be placed on a webpage. The communication unit communicates with a user terminal of the user. The control unit sends a webpage on which the first content is placed to the user terminal in a case where the control unit receives a display request of the webpage from the user terminal and where the display request includes information indicating that a second account of the user has been linked to the first account and sends a webpage on which the second content is placed to the user terminal in a case where the control unit receives the display request of the webpage from the user terminal and where the display request includes information indicating that the second account has not been linked to the first account or does not include the information indicating that the second account of the user has been linked to the first account.

An on-board update device that acquires an update program transmitted from an external server located outside a vehicle, and performs processing to update a program for an on-board ECU provided in the vehicle, the on-board update device including a control unit that controls transmission of the update program to the on-board ECU, wherein, when the transmission is to be resumed after an interruption of the transmission, if identification information of the on-board ECU is different from the identification information before the interruption of the transmission, the control unit determines that the on-board ECU has been replaced during the interruption of the transmission, and performs predetermined processing.

Techniques manage a Redundant Array of Independent Disks (RAID). In such a technique, in response to receiving information indicative of an end-of-life (EOF) of a first storage device of the RAID, a storage extent associated with the first storage device is determined, the storage extent being distributed over a plurality of storage devices of the RAID and including a first group of slices in the first storage device, the storage extent including a plurality of data blocks stored thereon. A portion of a data block of the plurality of data blocks is read from a first slice of the first group of slices, the first slice comprising the portion of the data block. The portion of the data block is written into a spare slice.

A system generating, using a first addressable unit address decoder, a first addressable unit address based on an input address, an interleaving factor, and a number of first addressable units. The system then generating, using an internal address decoder, an internal address based on the input address, the interleaving factor, and the number of first addressable units. Generating the internal address includes: determining a lower address value by extracting lower bits of the internal address, determining an upper address value by extracting upper bits of the internal address, and adding the lower address value to the upper address value to generate the internal address. Using an internal power-of-two address boundary decoder and the internal address, the system then generating a second addressable unit address, a third addressable unit address, a fourth addressable unit address, and a fifth addressable unit address.

A method for identifying a mechanical impedance of an electromagnetic load may include generating a waveform signal for driving an electromagnetic load and, during driving of the electromagnetic load by the waveform signal or a signal derived therefrom, receiving a current signal representative of a current associated with the electromagnetic load and a back electromotive force signal representative of a back electromotive force associated with the electromagnetic load. The method may also include implementing an adaptive filter to identify parameters of the mechanical impedance of the electromagnetic load, wherein an input of a coefficient control for adapting coefficients of the adaptive filter is a first signal derived from the back electromotive force signal and a target of the coefficient control for adapting coefficients of the adaptive filter is a second signal derived from the current signal.

Aspects of the present disclosure involve a system comprising a computer-readable storage medium storing at least one program and a method for providing games in a chat interface. A conversation interface is presented in a messaging application to enable a plurality of participants in a conversation to exchange messages with each other. A request from a first participant of the plurality of participants is received to launch a gaming application. In response to receiving the request from the first participant, a first message is transmitted to a second participant of the plurality of participants that indicates the first participant has launched the gaming application. In response to receiving the first message, an option is presented to the second participant in the conversation interface, the option associated with the gaming application to enable the second participant to join the first participant in the gaming application.
