In this paper, we proposed a new architecture of multiplier-and-accumulator (MAC) for high-speed arithmetic.By combining multiplication with accumulation and devising a hybrid type of carry save adder (CSA), the performance was improved. Since the accumulator that has the largest delay in MAC was merged into CSA, the overall performance was elevated. The(More)
In this paper, we propose a wavelet-based audio watermarking algorithm that is robust against capturing attack. With a commercial capturing tool, it is possible to capture various audio contents without noticeable degradation, and thus can potentially facilitate the illegal distribution of the audio content. By adjusting the mean value of the lowest subband(More)
Currently, kinetic analyses using dynamic positron emission tomography (PET) experience very limited use despite their potential for improving quantitative accuracy in several clinical and research applications. For targeted volume applications, such as radiation treatment planning, treatment monitoring, and cerebral metabolic studies, the key to(More)
Widespread popularity of wireless data communication devices, coupled with the availability of higher bandwidths, has led to an increased user demand for content-rich media such as images and videos. Since such content often tends to be either private, sensitive, or paid for, there exists a requirement for securing such communication. However, solutions(More)
UNLABELLED (111)In-Capromab pendetide imaging is indicated for postprostatectomy patients at risk for residual or recurrent disease. However, this study is complicated by relatively long times for tumor uptake and background washout that require imaging to be performed several days after radiopharmaceutical administration. In addition, (111)In-capromab(More)
