Quinary phase-field model was extended and constructed, and the diffusion-controlled phase decomposition and morphology in thermal aging Fe–Cu–Mn–Ni–Al quinary system coupled with CALPHAD thermodynamic databases were successfully studied. The effects of Manganese composition on the morphology, volume fraction, number density, particles size and growth and coarsening of Cu-rich precipitates were investigated...
A novel adaptive real-time image compression framework based on TMS320C6713 is presented in this paper. Via analyzing image texture, different compression ratio is applied for reducing the code stream. Owing to its low-cost, highspeed and low power performances, C6713 is selected as the main processor of framework. Firstly, the original image is transformed through lifting wavelet transform algorithm...
This paper mainly discusses airport target detection in remote sensing images. A new algorithm based on JPEG2000 compressed domain is proposed. Since the amount of remote sensing image data is generally large, images usually are compressed by JPEG2000. Therefore, this paper proposes an airport detection method for remote sensing image based JPEG2000 compressed domain. In the case of JPEG2000 compressed...
The traditional design of space communication systems is based on DSP+FPGA architecture. The data processing ability of DSP will be fall off with the increasing of communication channel access-number. In order to meet the needs of high-speed and large amount of data transmission, a kind of space communication system with SOPC architecture design which consists of five microprocessors and 32 HDLC communication...
The traditional grid design for securing reliability and trade-offs between lines and plants economically can no longer satisfy new role of power grid in open power market environment. Following deregulation of the electricity supply industry, the role of power grid has changed profoundly including a need to provide open access to all generators of large and small scale of which the grid is simply...
