An improved system and method for a distributed column chunk data store is provided. A distributed column chunk data store may be provided by multiple storage servers operably coupled to a network. A storage server may include a database engine for partitioning a data table into the column chunks for distributing across multiple storage servers, a storage shared memory for storing the column chunks during processing of semantic operations performed on the column chunks, and a storage services manager for striping column chunks of a partitioned data table across multiple storage servers. Any data table may be flexibly partitioned into column chunks using one or more columns as a key with various partitioning methods. There may also be a storage policy for specifying how to partition a data table for distributing column chunks across multiple servers and for specifying a level of redundancy for recovery from failure of storage servers.

A short-range wireless system and method is disclosed to store and transfer a new type of multimedia data construct called a tag. A user can write text, create a voice clip and append it to the text, take a digital picture and append it to the text, to create a multimedia file as the content of a tag. The creation or modifying of the multimedia file can be done in the user's mobile wireless device or off line and then stored in the mobile device. The multimedia file is then incorporated into the tag or it can be referenced by a pointer in the tag. The multimedia file is artistic expression of the user and the tag uniquely associates the user's identity with the multimedia file by prohibiting alteration of the content after the user completes its creation. A content-originator flag (CFG) value in the tag is set to “false” during the period when the user is creating or modifying the tag's content. When the user completes editing the content of the tag, the content-originator flag (CFG) value is set to true, thereby freezing the content. The tag includes the user's ID, such as his / her international mobile subscriber identity (IMSI) or mobile station ISDN number (MSISDN). Subsequent viewers of the content can make a copy of the content and can then modify it, but they cannot authentically attribute the modified copy to the original user. The system can be implemented as a wireless personal area network (PAN) such as provided in the Bluetooth Standard or a wireless local area network (LAN) such as provided in the IEEE 802.11 Wireless LAN Standard and the HIPERLAN Standard.

Improved duplicate and near-duplicate detection techniques may assign a number of fingerprints to a given document by (i) extracting parts from the document, (ii) assigning the extracted parts to one or more of a predetermined number of lists, and (iii) generating a fingerprint from each of the populated lists. Two documents may be considered to be near-duplicates if any one of their fingerprints match.

An improved system and method for compression in a distributed column chunk data store is provided. A distributed column chunk data store may be provided by multiple storage servers operably coupled to a network. A storage server provided may include a database engine for partitioning a data table into the column chunks for distributing across multiple storage servers, a storage shared memory for storing the column chunks during processing of semantic operations performed on the column chunks, and a storage services manager for striping column chunks of a partitioned data table across multiple storage servers. Any data table may be flexibly partitioned into column chunks using one or more columns with various partitioning methods. Domain specific compression may be applied to a column chunk to reduce storage requirements of column chunks and increase transmission speeds for sending column chunks between storage servers.

A decoder of LDPC codewords using the iterative belief propagation algorithm stores a posteriori information on variables. An updating device updates the a posteriori information on variables, and a first computation device computes variables to constrain messages from a posteriori information on variables and variable to constraint messages from previous iteration. A second computation device computes a constraint to variable messages from variable to constraint messages computed by the first computation device. A further computation device updates the a posteriori information on variables. A shuffle device transfers the a posteriori information on variables to the first computation device, and a further shuffle device transfers information from the second computation device to the storing device. The decoder further includes a device for compression-storage-decompression of the constraint to variable messages. The disclosure also relates to a corresponding method, computer program and system.

Method of registering a mobile subscriber in a mobile network and network unit for a mobile network having a home location register in which data related to a plurality of active mobile subscribers are stored. A first attempt of a mobile subscriber to attach to the mobile network is detected, and subsequently the home location register is updated by entering data related to the mobile subscriber in the home location register. Data related to a mobile subscriber which is not yet registered in the home location register may be stored in a second register, and the data related to the mobile subscriber is transferred from the second register to the home location register upon detection of the first attempt.

The present invention is a video on demand service enabled from a near video on demand service. A desired program is split into portions, or clips. The first clip is delivered a priori to the customer's Digital Video Recorder (DVR) using a hidden channel and it is made available for purchase on demand. The remaining portion is broadcast regularly using the start time of the Near Video On Demand service, for as long as the program is available for Video On Demand purchase. Upon purchase, the remaining portion is authorized for capture by the DVR. The clips are spliced together upon playback to form a complete program.

A method and a system for detecting cardiac arrhythmias that includes detecting RR intervals of the patient wherein each RR interval is an interval between two heart beats, and simulating standard probability density histograms of ΔRRs by means of a suitable probability distribution calculated through at least one mathematical formulae, wherein ΔRR is a difference between two successive RR intervals. Test probability density histograms of ΔRRs of the patient are constructed from the detected RR intervals. Finally, the standard and test histograms are compared to detect whether the patient suffers from cardiac arrhythmia. As non limiting examples, the standard probability density histograms of ΔRRs are modeled by a mathematical equation selected from the group consisting of: the Lorentzian distribution, the Gaussian distribution, the Student's t-distribution, and a probability distribution including a linear combination of the Lorentzian and Gaussian distribution.
