The coding efficiency of H.264/AVC standard is improved twice as large as that of MPEG-2 standard, yet its computational complexity is also greatly increased. Coupled with the real-time computing constraints in the actual application environment, the hardware implementation of H.264/AVC decoding chipset is a huge challenge. Based on H.264/AVC SoC platform solution, a reconfigurable intra prediction decoder is proposed in this paper. All the parallel arithmetic units are concentrated in a computing module, and the input data of the computing module are controlled in different modes, respectively, to achieve the reconfigurable architecture of predictor. Meanwhile, four parallel modules of the same structure are adopted to improve the processing capacity, so that the predicted values of four pixels can be generated simultaneously. Simulation results show that the design is very suitable to be integrated into H.264/AVC decoding chipset. © Sila Science. All rights reserved. Source

An integrated Micro Attitude Heading Reference System(MAHRS) based on Micro-electro-mechanical System(MEMS) gyroscopes, accelerometers, and magnetic-sensors was researched for Micro Aerial Vehicles (MAV). As traditional algorithms could not keep the attitude accuracy of the MAV during a long-time maneuvering, an adaptive attitude estimation filtering algorithm with low-cost multi-sensors was presented for the MAHRS. Firstly, this algorithm was used to establish the models of acceleration and magnetic-disturbance and took them into a state equation. In this way, it could maintain the attitude accuracy of loads during the long-time maneuvering. Then, this algorithm adopted the federated filter mode to reduce the interaction between acceleration and magnetic disturbance to improve its precision and reliability. Moreover, the algorithm made the estimation variance (P) and measurement variance (R) remain steady adaptively during different maneuvering states. By comparing with other different algorithms for the MAHRS, It shows that the presented algorithm is more accurate and reliable than other algorithms during various maneuvering states. Source

The vector correlations between products and reagents for the reactions F + HH → HF + H, F + HD → HF + D and F + HT → HF + T, have been investigated using the quasi-classical trajectory (QCT) method on the Stark-Werner (SW) ab initio potential energy surface. The distribution P(θr) of angle between k′ and j′, the distribution P(φr) of dihedral angle denoting k-k′-j′ correlation are calculated. The polarization dependent generalized differential cross sections have also been studied. The evident influence of isotope substitution on the product polarization is revealed. This effect may be derived from the different mass factor of the three reactions and the barrier height of the F + H2 PES. © 2011 World Scientific Publishing Company. Source

This study investigated the dissolution kinetics of silver nanoparticles in presence of natural organic matter. Silver nanoparticles were synthesized using chemical reduction method. Particle size and surface charges of the synthesized silver nanoparticles were characterized using a zetasizer. ICP-MS combined with ultrafiltration technology was used to quantify the silver nanoparticle dissolution in presence of natural organic matters. The obtained results suggested that the dissolution rate of silver nanoparticles decreases with increasing natural organic matter content. Our study provides important guidance in elucidating the transport and fate of silver nanoparticles in natural water conditions. © 2014 VBRI press. Source
