A hybrid concatenated code with two interleavers is the parallel concatenation of an encoder, which accepts the permuted version of the information sequence as its input, with a serially concatenated code, which accepts the unpermuted information sequence. The serially concatenated code consists of an outer encoder, an interleaver, and an inner encoder. An upper bound to the average maximum-lik...

We consider repairable threshold schemes (RTSs), which are threshold schemes that enable a player to securely reconstruct a lost share with help from their peers. We summarise and, where possible, refine existing RTSs and introduce a new parameter for analysis, called the repair metric. We then explore using secure regenerating codes as RTSs and find them to be immediately applicable. We compar...

Our work focuses on the recovery solutions for XORbased erasure codes. We point out that regenerating codes [5] have recently been proposed to minimize the recovery bandwidth in distributed storage systems. The idea is that surviving storage nodes compute and transmit linear combinations of their stored data during failure recovery. On the other hand, in XOR-based erasure codes, we do not requi...

The authors develop a class of codes for quantised generalised Gaussian (GG) sources. This new class of codes, that are called hybrid Golomb (HG) codes, are hybrids of Golomb–Rice (GR) codes and exp-Golomb (EG) codes. They integrate the properties of both GR and EG codes, which makes their performance more robust under variable source parameters. The efficiencies of the three classes of codes a...

Simple (dorsal light reflex) and complex (predator-prey interactions) visually mediated behaviors were used concurrently with morphological examination to assess restoration of visual function following optic nerve crush in bluegill (Lepomis macrochirus) x pumpkinseed (Lepomis gibbosus) hybrid sunfish. Regenerating optic nerve axons projected into the stratum opticum-stratum fibrosum et griseum...

Fast and efficient failure recovery is a new challenge for cloud storage systems with a large number of storage nodes. A pivotal recovery metric upon the failure of a storage node is repair bandwidth cost which refers to the amount of data that must be downloaded for regenerating the lost data. Since all the surviving nodes are not always accessible, we intend to introduce a class of maximum di...

In this paper, we propose and analyze a new hybrid FEC/ARQ scheme using rate compatible punctured serial concatenated convolutional codes (SCCCs) which is suitable for flat-fading channels. Puncturing increases the transmitted code rate, and the rate compatibility criterion allows incremental redundancy to be transmitted after each decoding failure according to a code-combining type-II Hybrid A...
