Based on the Joint Video Team (JVT) of the ITU-T Video Coding Experts Group VC EG and the IS O/IEC Moving Picture Experts Group MPEG, an RD optimal Macro Block mode decision scheme for Internet error channel streaming is introduced. The scheme employs the luminance Rate Distortion (RD) optimal mode decision scheme so as to take the effects of video encoding distortion and the channel error propagation to get higher error robustness for error transmission. Based on the Wireless Sensor Network, this paper analyzes the data distortion problem when transmitting H.264 coded video stream over error-prone channel. And the authors also have discussed a widely accepted technique that introduces more intra-coded information on macro block basis. Additionally, this paper introduces a simple loss and multiplication factor estimation method, the rate-distortion optimized assessing strategy over the whole situation. © (2013) Trans Tech Publications, Switzerland.

Silver nanoparticle arrays are well known to show characteristic surface plasmon properties sensitively dependent on the particles size, shape, surrounding dielectric and so on. In the present study, we investigated the influence of the silver film thicknesses, the dielectric materials and the annealing temperatures on the morphologies and the corresponding optical properties of silver nanoparticle arrays produced by thermal treatment of silver thin films. Different levels of dependence of array morphologies on the original silver film thicknesses, the dielectric environment and annealing conditions were identified. The variations of surface plasmon absorption bands can be correlated and explained by the morphological features, such as the particle size, aspect ratio, and coverage fraction. This correlation may be employed for the manipulation of desirable optical properties. Moreover, we attempted to integrate silver nanoparticle arrays into crystalline silicon solar cells and excellent light-trapping and spectrum-modification performance was observed. © 2014 The Royal Society of Chemistry.

Effects of Sr content and the vibration solidifying amplitude on the microstructure and mechanical properties of cast AM50-Y magnesium alloy were studied. The results show that with the increase of amplitude, the grain size of the alloy decreases, the bulk or bandlike phase in mircostructure of the alloy becomes to dispersive spots and the tensile strength, yield strength and elongation increase gradually that reaches maximum value when the amplitude is 2.5 mm. With the increase of Sr content, the grain size of the alloy with 2.5 mm amplitude is smaller than that without vibration alloy, the tensile strength, yield strength and elongation increase.

The tungsten inert gas welding–brazing process using Al-based filler metal has been developed for joining 5052 Al alloy to Ti–6Al–4V alloy in a butt configuration. The results indicated that heat input influenced the morphology and thickness of the interfacial reaction layer of Al/Ti joints, which played an important role in the mechanical properties of weldment. With the optimised tungsten electrode offset D of 1.0 mm from Al/Ti initial interface to Al side and welding current of 70 A, the thin cellular-shaped and club-shaped TiAl3 reaction layers formed in the brazing zone, which contributed to suppressing crack initiation and propagation during tensile test. Eventually, the maximum tensile strength of 183 MPa was obtained and the optimised Al/Ti joint fractured at Al alloy base plate. Moreover, the power density characterisation and joining mechanism of Al/Ti joints were discussed. © 2016 Institute of Materials, Minerals and Mining

This paper puts forward a type of device which can automatically measure the operation status of the module exchange in 112-system according to the measuring problems in the terminations of both the small-capacitance telephones and the burglar alarms. In this device, the measuring method of three-terminal phase is adopted, which can effectively measure the electric resistance and capacitance between the different layers of the lines. Therefore, it can complete the measurement of the subscriber lines. In addition, it is able to measure different types of switches and a variety of lines, and especially adds the measurements on the noise and the degree of balance. After its system goes through rigorous tests, the errors are measured to fulfill users' demands, and thereby the purposes of saving manpower and improving the efficiency of measurement and feedback can be achieved. © 2011 Published by Elsevier Ltd.

For the problem of graph clustering data analysis lacking adaptation of the increasingly complex distributed cluster environment in artificial intelligence, an efficient sparsification algorithm based on parallel computing (MR-LSH) is proposed in this paper. Minhash algorithm is analyzed and improved by the algorithm based on MapReduce framework theory which makes graph cluster process efficient in increasingly complex distributed cluster environment. The feasibility and high efficiency of algorithm in quick sparse processing graph cluster data are proved in the simulation. © Springer India 2016.

Image retrieval based on the characteristics of the color mostly in the color of the image histogram as color features, this kind of image retrieval method has the advantages of simple efficient, but has lost the color of the spatial distribution of information. This paper puts forward a comprehensive mass-tone attune method and block the Lord of color image retrieval method, With the complexity of the lowest mass-tone attune method to traverse the database, take Euclidean distance the smallest pictures into block mass-tone method; Then the two retrieval results after comprehensive consideration before take a few images to give users; Finally the related feedback algorithm, improve the accuracy of image retrieval. The experimental results show that, when the picture has a significant objects, this method and color histogram compared, can more accurate and efficient to find out the content of the customer need image, obviously improve the retrieval precision.
