We present a generalised and improved version of the category attack on LSB steganography in JPEG images with straddled embedding path. It detects more reliably low embedding rates and is also less disturbed by double compressed images. The proposed methods are evaluated on several thousand images. The results are compared to both recent blind and specific attacks for JPEG embedding. The propos...

Dr. Carl Rogers, the American psychologist and founder of what has now become known as person-centred counselling or psychotherapy, has always claimed to be grateful that he never had one particular mentor. He has been influenced by many significant figures often holding widely differing viewpoints; but above all he claims to be the student of his own experience and of that of his clients and c...

This paper describes new methods for producing optimal binary signed-digit representations. This can be useful in the fast computation of exponentiations. Contrary to existing algorithms, the digits are scanned from left to right (i.e., from the most significant position to the least significant position). This may lead to better performances in both hardware and software.

The least significant digit first decomposition of integer vectors into words of digit vectors provides a natural way for representing sets of integer vectors by automata. In this paper, the minimal automata representing Presburger sets are proved structurally Presburger: automata obtained by moving the initial state and replacing the accepting condition represent Presburger sets.

Some properties of beamstrahlung are discussed, and plans to observe the effect at SLC by the use of Cherenkov counters are illustrated. Invited talk presented at the International Conference on Advances in Experimental Methods for Colliding Beam Physics, Stanford, California, March 9-13, 1987 * Work supported by the Department of Energy, contract DE A C 0 3 7 6 SF 00 5 15.

While there have been a number of studies on the effect of leak site and shape on the magnitude of measured leakage through respirator face seals, there have been very few studies to identify the location and size of these leaks. In a previous study we used a method of identifying the location and shape of respirator leaks on a half-mask respirator by the deposition of a fluorescent tracer duri...

background: gifted students have many personality traits that can improve them to experiences achievement. some factoers such as openness to experience and self-reference aid us to find relationship between these factors and others dimensions. methods: the relationship between personality traits, self-awareness, and self-actualization dimensions was assayed among 239 gifted students from shiraz...

background: breast cancer is the most common type of cancer and second leading cause of death in women after lung cancer. the world health organization has reported that breast cancer, with 502,000 deaths in 2005, surpassed lung, stomach, colorectal, and cervical cancers as the leading cause of death in women. the main objective of the current study was to examine the predictive role of emotion...
