In this study, a microchannel heatsink with working fluid containing phase change material has been investigated numerically. The addition of phase change material in working fluid is to increase the heat transfer rate during cooling process. Commercial software ANSYS Fluent 15.0 is utilized to study the thermal resistance of the microchannel heatsink. Properties of working fluid with phase change...
In this work, we develop a novel robust scheme of two-dimensional unequal error protection (2D-UEP) for the H.264 scalable video coding (H.264/SVC) with a combined temporal and quality (SNR) scalability over packet-lossy networks. The proposed scheme combines error resilience techniques and importance measures in video coding. To avoid the waste of bits and obtain the best rate allocation, we develop...
In this paper, we proposed a low complexity subdivision algorithm to approximate Phong shading. It is a combination of a subdivision scheme using forward difference and a recovery scheme to prevent rasterization anomaly. Dual space subdivision, triangle filtering and variable sharing schemes are also proposed to reduce the computation. Compared with the conventional recursive subdivision shading algorithm,...
An innovative multi-mode depth buffer compression algorithm has been developed for 3D graphics system. It adaptively compresses the depth buffer data according to different scene changes by employing 19 compression modes generated from three compression algorithms including DDPCM, HA, and general DDPCM. Furthermore, this novel algorithm supports one-plane and two-plane compression modes and manipulates...
Depth buffer bandwidth reduction is one of the most important issues in bandwidth-limited 3D computer graphics system. In this paper, we propose a reconfigurable algorithm for depth buffer compression. For 8times8 tile size and 16-bit depth values, the proposed algorithm can achieve 1.91:1 compression ratio on average and improve 76.9% and 39.4% compared with HA in Hasselgren, J, (2006) and DDPCM...
