Heart rate variability (HRV) is a measure of variations in the heart rate. Over the last 25 years, HRV analysis has became popular as a non-invasive research and clinical tool for indirectly investigating both cardiac and autonomic nervous system (ANS) function in both health and disease area. How the musical rhythmic characteristics, tempo and complexity, affect the performance of HRV is studied in this work. By understanding the relationship between music and the function of ANS, the novel biomedical entertainment platform is proposed and used for relaxation.

Heart rate variability (HRV) is a measure of variations in the heart rate. Over the last 25 years, HRV analysis has became more and more popular as a non-invasive research and clinical tool for indirectly investigating both cardiac and autonomic nervous system (ANS) function in both health and disease area. How the musical rhythmic characteristics, tempo and complexity, affect the performance of HRV is studied in this work. By understanding the relationship between music and the function of ANS, we can improve our life and health by music - non-invasively and simply.

To satisfy the high quality image compression requirement, the new, JPEG XR compression standard is introduced. The analysis and architecture design with VLSI architecture of JPEG XR encoder are proposed in this paper which can encode 4:4:4 1920 x 1080 high definition photo in smooth. According to the simulation results, the throughput of the proposed design can encode 44.2 M samples/sec. This design can be used for digital photography applications to achieve low computation, low storage, and high dynamical range features.

With rapid progress of sensors, display devices, and computing engines, image application exists everywhere. High quality, high compression rates of digital image and low computational cost are important factors of consumer electronics. In this paper, we proposed a 4:4:4 lossless JPEG XR encoder design. In JPEG XR encoder, entropy coding is a critical module of encoder. We proposed a well-defined timing schedule of pipeline architecture to speed up the entropy encoding, which is the most computationally intensive part in JPEG XR encoder. This design can be used for the digital photography applications to achieve the low complexity of computation, low storage, and high dynamic range.
