Lossless Snubber Cell for a Soft-Switched Bidirectional Buck–Boost Converter
In this paper, we propose a lossless snubber cell for a soft-switched bidirectional buck-boost converter (BBC). The proposed snubber cell provides all switches with soft-switching conditions in both the bidirectional power flows of the BBC.

An Enhance Scheme of Visual Secret Share for Lossless Recovery
Algorithms in Visual Cryptography usually uses a sharing scheme where instead of sharing the secret or message directly, it is embedded into multiple shares which are then shared between the intended individuals whereby upon receiving them the decrypting algorithm on the receiving end restores the original secret.

Adaptive Unified Data Embedding and Scrambling for Three-Dimensional Mesh Models
Traditionally, unified data embedding and scrambling techniques have been designed for grayscale images, which cannot be applied directly to a three-dimensional (3D) mesh. Recently, the universal use of 3D technology inspired us to innovate in this field.

Practical Secret Image Sharing Based on the Chinese Remainder Theorem
Compared with Shamir’s original secret image sharing (SIS), the Chinese-remainder-theorem-based SIS (CRTSIS) generally has the advantages of a lower computation complexity, lossless recovery and no auxiliary encryption. However, general CRTSIS is neither

Weighted visual secret sharing with multiple decryptions and lossless recovery
Traditional visual secret sharing (VSS) encodes the original secret image into n shares, and each share is of equal importance. However, in some scenarios, we need to make a difference between the participants according to the levels of their importance. Therefore, the capability of each share to recover the original secret image will be different.

Data Hiding and Authentication Scheme for Medical Images Using Double POB
To protect the security of medical images and to improve the embedding ability of data in encrypted medical images, this paper proposes a permutation ordered binary (POB) number system-based hiding and authentication scheme for medical images, which ...

Compression-Assisted Adaptive ECC and RAID Scattering for NAND Flash Storage Devices
NAND flash memory-based storage devices are vulnerable to errors induced by NAND flash memory cells. Error-correction codes (ECCs) are integrated into the flash memory controller to correct errors in flash memory. However, since ECCs show inherent limits
