    David Scott has written a bijective BWT transform, which brings all the advantages of bijectiveness to BWT based compressors. Among other things, making BWT more suitable for compression-before-encryption and also give (slightly) better compression.

    Jarek Duda’s “Asymmetric Binary System” promises to be an alternate to arithmetic coding, having all the advantages, but being much simpler. Matt has coded a PAQ based compressor using ABS for back-end encoding. Update: Andrew Polar has written an alternate implementation of ABS.

Mobile tech. devised to show routes to safety in case of disaster

Posted by Sachin Garg on 16th January 2006 | Permanent Link

TMCnet: Mitsubishi Electric Corp., NTT DoCoMo Inc. and Pasco Corp. said Monday they have jointly developed a technology to provide cellphones and other mobile terminals with three-dimensional, real-time information on routes for escape to safety in the case of natural disasters such as earthquakes.

The new technology is based on an advanced data-compression technology, which has made it possible to distribute 3D information via mobile terminal, and utilizes Pasco’s aerial photographic surveying technology.

The three companies have developed the technology on behalf of the Ministry of Internal Affairs and Communications which launched a three-year program in April 2003 to devise practical applications of the next-generation geographic information system.

It has yet to be decided when to put the new mobile technology into use.
