In a disk array environment such as a Redundant Array of Independent Disks-6 (RAID-6) environment, the overall performance overhead associated with exposed mode operations such as resynchronization, rebuild and exposed mode read operations is reduced through increased parallelism. By selecting only subsets of the possible disks required to solve a parity stripe equation for a particular parity stripe, accesses to one or more disks in a disk array may be omitted, thus freeing the omitted disks to perform other disk accesses. In addition, disk accesses associated with different parity stripes may be overlapped such that the retrieval of data necessary for restoring data for one parity stripe is performed concurrently with the storage of restored data for another parity stripe. |

Encoded transmission
Significant improvement in Raptor codes and punctured LDPC codes are obtainable by use of the invention. In both a transmission scheme for Raptor-encoded or LDPC-encoded information, a dynamic adjustment approach is employed. A fraction of a codeword or information frame is transmitted. A feedback signal is sent from the receiver to the transmitter indicating either 1) successful decoding, or 2) failure to decode and/or a feedback signal indicative of a statistical measure of transmission channel quality. If decoding fails, a further portion of the codeword or frame is sent. The intensity and/or size of the fraction is adjusted based on the feedback signal. In one embodiment, a specific range for probabilities employed in the encoding process for Raptor codes provides the ability to increase transmission throughput. Further it has been found that the advantageous Raptor codes are useful in noise conditions where even the improved punctured LDPC codes of the invention begin to degrade. |

Method, system and computer program for providing web pages based on client state
The invention proposes a solution allowing a web application to generate a response page based on local information of a client. For this purpose, a front-end servlet (receiving a request from the browser of the client) verifies (318, 360) whether the local information is available on the server. If not, a wait page with a command for uploading the local information is generated and sent (321) to the client, so as to cause the client to transmit (327-342) the local information to a back-end servlet of the server. The wait page self-refreshes (348-357) after a predefined delay; in response thereto, the same front-end servlet verifies whether the local information is ready to use. If the uploading is still in progress, a wait page without the upload command (which self-refreshes after the same delay) is generated and sent (363) again. Once the uploading has been completed, the front-end servlet can generate and send (366-372) the desired response page based on the up-to-date local information of the client. |

Network routing using link failure information
Link failure messages are sent through a network to accelerate convergence of routing information after a network fault. The link failure messages reduce the oscillations in routing information stored by routers, which otherwise can cause significant problems, including intermittent loss of network connectivity as well as increased packet loss and latency. For example, the link failure messages reduce the time that a network using a path vector routing protocol, such as the Border Gateway Protocol (BGP), takes to converge to a stable state. More particularly, upon detecting a network fault, a router generates link failure information to identify the specific link that has failed. In some types of systems, the router communicates the link failure information to neighboring routers as well as a conventional update message withdrawing any unavailable routes. Once other routers receive the link failure information, the routers do not attempt to use routes that include the failed link. |

Liquid crystal display device
The present invention provides a liquid crystal display device which can enhance quality and reliability of image display by preventing the generation of bubbles in the inside of a liquid crystal display panel and, at the same time, by suppressing leaking of light from an end of a black matrix film. In the liquid crystal display panel which sandwiches a liquid crystal layer between two glass substrates, the liquid crystal layer is surrounded by a sealing material having a predetermined width. On one glass substrate, a black matrix film and an overcoat film are arranged from one-glass-substrate side such that the black matrix film and the overcoat film overlap the sealing material. The black matrix film is, in the widthwise direction of the sealing material, formed into a planar flat black matrix film until a middle position of the sealing material from a side on which the liquid crystal layer is arranged, and is formed into a slit-shaped slit black matrix film from the middle position. Due to such a constitution, an adhesion area between the glass substrate and the overcoat film under an applied region of the sealing material is enlarged and hence, an adhesion strength is increased thus largely enhancing an adhesion strength. |
