In the presence of a periodic external drive, mean value energy two-level quantum system (or qubit) displays well-known Rabi oscillatory dynamics that is usually described within rotating wave approximation. order to calculate its standard deviation, we get rid this latter and obtain huge ratio (of unity) deviation over value. This due large-amplitude high-frequency oscillations internal as wel...

The recently proposed forced convergence technique allows for reducing the decoding complexity of Low−Density Parity−Check Codes (LDPCC) at only slight deterioration in performance. The basic idea is to restrict the message passing during LDPC decoding to the nodes that still significantly contribute to the decoding result. In this paper, we propose to add a bit−flipping post−processor to the f...

In this article, a fabulous method for database retrieval is proposed.  The multi-resolution modified wavelet transform for each of image is computed and the standard deviation and average are utilized as the textural features. Then, the proposed modified bit-based color histogram and edge detectors were utilized to define the high level features. A feedback-based dynamic weighting of shap...

Recently Papadimitriou has proposed a randomised ‘bit flipping’ method for solving the 2-satisfiability problem; and the author has proposed a randomised recolouring method which, given a 3-colourable graph, finds a 2-colouring of the vertices so that no triangle is monochromatic. Both methods involve finding a ‘bad’ configuration (unsatisfied clause, monochromatic triangle) and randomly changi...

In this paper we present the behavior of JPEG2000 coding scheme over noisy or congested communication channels and highlight the cost analysis aspect. Two error schemes are considered including bit errors and packet dropping effects. Two bit error methods are used, consisting of flipping or dropping the bits, and various packet sizes are put to the test of packet dropping. Extensive performance...

Die-rolling is the cryptographic task where two mistrustful, remote parties wish to generate a random D-sided die-roll over a communication channel. Optimal quantum protocols for this task have been given by Aharon and Silman (New Journal of Physics, 2010) but are based on optimal weak coin-flipping protocols which are currently very complicated and not very well understood. In this paper, we f...

In der vorliegenden Arbeit wird ein Schema zur Korrektur von transienten Fehlern in eingebetteten, pegelgesteuerten Speicherelementen vorgestellt. Das Schema verwendet Strukturund Informationsredundanz, um Single Event Upsets (SEUs) in Registern zu erkennen und zu korrigieren. Mit geringem Mehraufwand kann ein betroffenes Bit lokalisiert und mit einem hier vorgestellten Bit-Flipping-Latch (BFL)...
