Steganography embeds a secret message in a seemingly innocuous cover-object. This paper presents a framework for steganography with executables as cover-objects built on top of an existing binary rewriter. Executables differ significantly from previously explored coverobjects, we thus first identify the cover-specific redundancies that can be used to embed a secret message. Techniques are then ...

The sensitivity of monolayers of Ilford L-4 nuclear emulsion to beta(-)-particles is approximately 0.20 grain per particle emitted for H(3), and 0.025 grain per particle for p(32). The sensitivity for thick layers is 1.3 grains per tritium beta(-)-particle emitted within the emulsion. In electron microscopic autoradiographs the maximum resolution is approximately 0.1 micron for H(3) and 0.3 mic...

Repeated modular additions and overflow detection are possible in redundant hybrid number systems (RHNS). In this paper a circuit is proposed that implements the overflow-detecting procedure in such systems and allows a mean addition time of about 10.5 gate delays for numbers having a magnitude order normally distributed in the range [−233, 233 − 1], versus a 14 gate delay required by 32-bit CL...
