Abstract: An erasure resilient coding (ERC) distributed data storage system and method for storing data in a reliable and survivable fashion while minimizing hardware and associated costs. The system and method includes forming multiple protection groups both within and across storage nodes of the storage system. Data is segmented into original data blocks and ERC data blocks. Load balancing occurs by interleaving storage nodes with equal numbers of original data blocks and ERC data blocks while ensuring each node has an equal number of combined read and write operations. Unique read and write operations on data block can be performed independent of other data blocks in a protection group. The write operation uses Galois field arithmetic and ERC transform to either write or append a new data block to a storage node. The read operation recovers data in a variety of ways using ERC decoding.

Abstract: A media recommendation and sharing technique that employs agents on media players/devices to expand the scope of media sharing scenarios. The technique assists a user in discovering media items, such as, for example, music, recordings, play lists, pictures, video games, on nearby media players or devices (devices which are capable of receiving, storing and playing media) which are interesting to the user. The collaborative media recommendation and sharing technique contemporaneously determines a user's media preferences based on media stored on a pair of media devices and recommends media for potential sharing based on these determined user preferences.

Abstract: A framework for facilitating collaborative interaction between users of a web application is presented. The framework provides persistence and sharing mechanisms for arbitrary application-defined objects. The sharing mechanism is coupled with a consistency mechanism that keeps client states consistent even when users perform conflicting operations. This framework is application-independent in that the persistence, sharing between clients and maintaining a consistent state among the clients is accomplished without the need for specific knowledge of the design of the web application. Thus, web developers can focus on the logic of the application and the UI, instead of spending time designing and implementing collaborative capabilities.

Abstract translation: 介绍了一种用于促进Web应用程序用户之间的协作交互的框架。 该框架为任意应用程序定义的对象提供持久性和共享机制。 共享机制与一致性机制相结合，即使在用户执行冲突操作时也能保持客户端状态的一致性。 该框架是独立于应用程序的，因为在客户机之间的持久性，共享和维护一致的状态之间完成了这一任务，而不需要Web应用程序的设计的具体知识。 因此，Web开发人员可以专注于应用程序和UI的逻辑，而不是花时间设计和实现协作功能。

Abstract: A method and system for modifying a digital audio signal to vary its playback speed while preserving the signal's pitch and quality. The variable speed playback (VSP) system and method mitigates artifacts remaining after processing by existing techniques. The VSP system and method produces a consistent and pleasing sound to an audio file, even while its speed is varied during playback. The VSP method includes selecting and estimating an input frame, adjusting the frame position, and overlapping and adding the adjust frame to an output signal. The frame position adjustment is achieved using an enhanced correlation technique that finds all local maxima over a cross-correlation function. The local maxima having a highest correlation score is designated as a cut position, where the adjusted frame is cut from the input buffer. The VSP system and method using four input frames to generate one output frame.
