Very fast method to synthesise conformal arrays

Doublet method for very fast autocoding

BACKGROUND Autocoding (or automatic concept indexing) occurs when a software program extracts terms contained within text and maps them to a standard list of concepts contained in a nomenclature. The purpose of autocoding is to provide a way of organizing large documents by the concepts represented in the text. Because textual data accumulates rapidly in biomedical institutions, the computation...

A Very Fast Method for Clustering Big Text Datasets

Large-scale text datasets have long eluded a family of particularly elegant and effective clustering methods that exploits the power of pair-wise similarities between data points due to the prohibitive cost, timeand space-wise, in operating on a similarity matrix, where the state-of-the-art is at best quadratic in time and in space. We present an extremely fast and simple method also using the ...

An approach to synthesise safe systems

Detectors are system components that identify whether the system is in a particular state. Detectors can be used to ensure arbitrary safety properties for systems, that is, they can be used to prevent the system from reaching a ‘bad’ state. Detectors have found application in the area of fault-tolerant systems but can also be used in the area of security. We present here a theory of detectors t...

A very fast parallel object store for very fast applications

An architecture for a memory-resident, Parallel and Persistent ObjectSTore (PPOST) is suggested. Different object-oriented databases might be built on top of PPOST. The term memory-resident (or main memory based) means that the primary storage device is main memory. Persistence is guaranteed automatically by managing secondary and stable storage devices (such as main memory with uninterrupted p...
