Steganography for Radio Amateurs - A DSSS Based Approach for Slow Scan Television
In 2005, Germany introduced a new Amateur Radio Ordinance prohibiting encrypted radio traffic at home. Crypto-bans can be circumvented using steganography. However, present steganographic methods are not eligible because the embedded message will not survive the usual distortions in a radio transmission. Robust as current watermarking methods are, they leave clearly detectable traces and have a...

We also briefly describe the application architecture and the interfaces developed to support major use cases that a wine amateur may require in order to store and manage information about wines.
متن کاملSensitivity Optimization for a New Radio-Chromic Dosimeter (PRESAGE)
Introduction: Different dosimetric modalities (e.g., ionization chambers, semiconductors, TLDs, radiographic films) often have some problems determining isodose curves and percentage depth doses in high dose gradient regions. Research has been ongoing to develop portable high resolution dosimetry devices with accurate absolute dosimetry capabilities and easy data analysis. The ‘PRESAGE’ dosimet...
