Abstract: An adaptive and scalable packet error correction apparatus and method in a wireless multicast network is provided. Each retransmission request from a receiver contains a round number and the number of repairs sent in that round. At each receiver, there are two counters for counting the rounds sent out on the network and the number of repairs that have been required. A receiver on the wireless multicast network listens to the ARQ requests sent by other receivers to update the two counters and determines whether its request should be suppressed or be sent out.

Abstract: Computer-implemented systems and methods are provided for assessing non-native spontaneous speech pronunciation. Speech recognition on digitized speech is performed using a non-native acoustic model trained with non-native speech to generate word hypotheses for the digitized speech. Time alignment is performed between the digitized speech and the word hypotheses using a reference acoustic model trained with native-quality speech. Statistics are calculated regarding individual words and phonemes in the word hypotheses based on the alignment. A plurality of features for use in assessing pronunciation of the speech are calculated based on the statistics, an assessment score is calculated based on one or more of the calculated features, and the assessment score is stored in a computer-readable memory.

Abstract: Provided are a method, system, computer storage device, and storage area network for maintaining a communication path from a host to a storage subsystem in a network. A storage subsystem controls data transfer and access to a storage devices in a network including a switch and a host. A topological storage stores topological coupling relationship between the host and the switch and a topological coupling relationship between the switch and the storage subsystem. In response to determining a failed path, the storage subsystem determines a first port on the storage subsystem in the failed path. The storage subsystem determines from the topology storage the topological coupling relationships between the host and the switch and the switch and the storage subsystem. The storage subsystem redirects, based on the topological coupling relationships, a message sent to the first port of the storage subsystem to an operational second port in the storage subsystem.
