Abstract: To study the problem of the identification of multiple ear tags of cattle occur data collision in the RFID network of pasture, the experiment use an improved anti-collision algorithm, it is combined bit locking with dynamic and analysis method, only colliding bits are processed by the method of binary, during transmission the data are dynamic, only send known information, which receive complementary bits of the known information, and then analyze the performance of the algorithm and simulation. The results show that compare with traditional binary algorithm, the improved algorithm from the operating frequency, transmission delay, data throughput have obvious advantages, the improved algorithm that could solve the problem of data collision cause by the cattle those wear ear tags get into radio frequency region, improve the efficiency of the tag identification.

Abstract: The article reports a laboratory experimental programme that investigated effect of metakaolin on the early strength of concrete made with ternary combinations of Portland cement (CEM I) with ground granulated blast slag (GGBS) and metakaolin (MK). The various level of cement combinations (65%CEM I+30%GGBS+5%MK, 45%CEM I+45%GGBS+10%MK and 45%CEM I+40%GGBS+15%MK) was examined in comparison to CEM I and equivalent GGBS binary concretes for up to 28 days. Results show that the reduction in early strength is greater with the higher cement replacement level. However, the ternary concrete containing 15%MK has minor increase in early strength compared to those with 10%MK but a significant increase in strength is examined at later age (28 days). It is concluded that the presence of MK compensates the adverse effect of GGBS at early strength development and improves the strength at later ages.

Abstract: Based on the detailed analysis of the STL file format, VC++ 6.0 programming language was used to extract the STL ASCII and binary file information, at the same time, using the OpenGL triangle drawing technology for graphical representation of the STL file, with rendering functions such as material, coordinate transformation, lighting, et al, finally realizing the loading and three-dimensional display of STL ASCII and binary file formats.

Abstract: Using logical criterion based on the characteristics of binary image, the normalized cross-correlation algorithm is improved. First, the binary of gray image is carried out. The target and the background are made a distinction between 0 and 1. Second, through the logic correlation matching, two images of the same location value equal to 1, otherwise 0. Finally, the correlation coefficient is calculated. The experimental results show that the improved normalized cross-correlation algorithm can speed up the matching, without affecting the accuracy of the matching.

Abstract: How effective and efficient to deal with the collision of tag identification is an important issue in RFID systems. In this paper, based on the existing binary anti-collision algorithm, added a sleep status bit to reduce data redundancy of readers sending commands and reduce the number of sending command by changing the order of search tag which the reader sent, and got an improved algorithm. Then used MATLAB to simulate this algorithms advantages in data amounts and sending times.

Abstract: First the traditional objects-attribute information table converted into a objects-attribute-attribute value table by using binary. Then two new concept is defined in this paper: concept vector instead of elementary sets (the equivalence classes of R) and knowledge matrix instead of equivalence relation of R by using binary system. Put forward a new solution to the lower and upper approximations support subset on rough set by using concept vector and knowledge matrix. Examples also are given.

Abstract: Study of the conflict questions of multiple miners (electronic tag) in the same RF induction area of the underground personnel positioning system. Analyze the Pure Aloha algorithm, Time Slot Aloha algorithm, Dynamic Framed slotted Aloha algorithm based on Binary algorithm. And put forward a kind of mixed anti-collision algorithm through improved.

Abstract: The paper deals with phase diagram calculations and predictions of selected binary, ternary, and Zr-Nb-O-H quaternary system. These systems are important as alloy base for cladding materials involving fissionable fuel in nuclear industry. The main attention is focused on the phase diagram prediction of Zr-1wt.%Nb-O alloy system at temperature conditions up to 2 000 °C. In addition, the influence of hydrogen content on the Zr-1wt.%Nb-O phase diagram is discussed. According to service conditions in nuclear industry, 1 000, 2 000 and 3 000 ppm of hydrogen contents are considered. The achieved results are presented as iso-concentration section of the phase diagrams. Impact on mechanical properties of the material under view is discussed.

Abstract: Frame theory has been the focus of active research for twenty years, both in theory and applications. In this work, the notion of orthogonal vector-valued binary small-wave wraps, which is a generalization of uni-wavelet packets, is introduced. A procedure for constructing them is presented. Their orthogonality traits are investigated by using time-frequency analysis method, matrix theory and finite group theory. Orthogonality formulas concerning these binary small-wave wraps are established. Orthonormal wavelet packet bases are obtained. The pyramid decomposition scheme is obtained based on such a GMS and a sufficient condition for its existence is provided.

Abstract: The article proposed a kind of new measuring technique suitable for pellet outer diameter --shading of measurement, using high quality laser as the light, linear CCD image sensor TCD1206 acts testing device, TCD1206 produced drive without delay by single-chip microcomputer, process pellet outer diameter signal coming from TCD1206 by floating threshold method of binary, finally the processed binary signals send back to the single-chip microcomputer, through MAX232 serial communication transfer to PC for displaying. The whole process realizes real-time detection to pellet outer diameter, and makes measurement system had higher precision.
