A novel Turbo Unequal Error Protection (UEP) coding scheme is proposed in this paper. In our scheme, two error protection levels of Turbo codes are achieved by a new rate-compatible puncturing mechanism. When coding with the Turbo UEP encoder, both of the two parity bits are reserved for the high error protection bits, and for the low error protection bits,(More)
Even in healthy subjects, the heart ages along with other organs of the body. A prominent change is progressive left ventricular (LV) diastolic dysfunction, even though LV mass increases slightly during aging. Accordingly, assessment of LV dysfunction can be employed as a surrogate marker of cardiac age. The clinical factors that may accelerate the cardiac(More)
In this paper, the Turbo-based unequal protection mechanism for reliable transmission of speech signal is studied. In order to obtain the hierarchical importance regularity of information bits for each sampling point, the changing value caused by the variation of each bit in 8-bit folded code of pulse-code modulation is first calculated. According to the(More)
In this paper, an effective self-embedding fragile watermarking method for tampering detection and content recovery is proposed. The halftone mechanism and the extension operation are utilized to generate recovery bits from the resized original image. Watermark bits including recovery bits and authentication bits only occupy one LSB plane of the original(More)
Modification of conventional Pt/C electrocatalyst with silicomolybdic acid (SiMoA) was performed using electrochemical cyclic voltammetry method. The modified and unmodified catalysts were tested under identical conditions for electrooxidation of CO, methanol, and ethanol. In the CO-stripping experiments, the modified catalyst was characterized by(More)
BACKGROUND Ultrasound measurements of the inferior vena cava (IVC) diameter (IVCD), together with its respiratory variation, provide a noninvasive estimate of right atrial pressure (RAP). However, there is a paucity of studies that have compared this technique with simultaneous catheterization. We explored the best cut-off values of IVC parameters for(More)
