In this paper, a new steganography scheme with high embedding payload and good visual quality is presented. Before embedding process, secret information is encoded as block using Reed-Muller error correction code. After data encoding and embedding into the low-order bits of host image, modulus function is used to increase visual quality of stego image. Since the proposed method is able to embed...

In order to reduce errors, error correction codes (ECCs) need to be implemented fast. They can correct the errors corresponding to the first few orders in the Taylor expansion of the Hamiltonian of the interaction with the environment. If implemented fast enough, the zeroth order error predominates and the dominant effect is of error prevention by measurement (Zeno Effect) rather than correctio...

Quantum error correcting codes have been shown to have the ability of making quantum information resilient against noise. Here we show that we can use quantum error correcting codes as diagnostics to characterise noise. The experiment is based on a three-bit quantum error correcting code carried out on a three-qubit nuclear magnetic resonance (NMR) quantum information processor. Utilizing both ...

This paper discusses the money demand function in China. We use Cointegration technique and Error Correction Model to estimate the long-run and short -run money demand function. We find that M2 aggregate appears to be cointegrated with price level and income. We also specified a satisfying error correction model for M2.

This paper describes the salient features of designing a robust forward error correction coding scheme for satellite data communications and considers various such schemes suitable for a short message application.

A′(n,d,e), the smallest ` for which every binary error-correcting code of length n and minimum distance d is decodable with a list of size ` up to radius e, is determined for all d ≥ 2e−3. As a result, A′(n,d,e) is determined for all e≤ 4, except for 42 values of n.

researchers have suggested that interactional feedback which is between teacher and learner during their writing is associated with l2 learning because it prompts learners to notice l2 forms. this paper reports a classroom-based study that investigated the role of feedback in socio-cultural theory. in this study, 12 efl learners performed on three writing tasks and were provided with a three-st...
