Henderson byte: Multiferroics

Multiferroics : Past , present , and future

© 2010 American Institute of Physics, S-0031-9228-1010-020-9 The interplay between electricity and magnetism has fascinated scientists and engineers for centuries, ever since Hans Christian Oersted noticed in 1820, quite by accident, that a magnetic compass needle deflected when he switched the current in a nearby battery on or off. Over the 40 years or so following Oersted’s observation, the c...

PACS images can be treated byte by byte

Our PACS project at the University Hospitals Leuven in Belgium radically follows from an overall IT perspective. The emphasis on image flow throughout the entire hospital supersedes operations within the image-generating departments. Image management outside the radiology department is not an afterthought, but rather an integral part in, and even a driving factor for, decisions that the departm...

Perfect Byte-Correcting Codes

We present a few new constructions for perfect linear single byte-correcting codes. These constructions generate some perfect single byte-correcting codes with new parameters, and some perfect single bytecorrecting codes with known parameters and simpler presentation and implementation over the known codes. It is also shown that nonequivalent perfect linear single byte-correcting codes exist wh...
