Cyclic codes with two zeros and their dual codes as a practically and theoretically interesting class of linear codes have been studied for many years and find many applications. The determination of the weight distributions of such codes is an open problem. Generally, the weight distributions of cyclic codes are difficult to determine. Utilizing a class of elliptic curves, this paper determines the weight distributions of dual codes of q-ary cyclic codes with two zeros for a few more cases, where q is an odd prime power. © 1963-2012 IEEE.

Signcryption, which was introduced by ZHENG, is a cryptographic primitive that fulfils the functions of both digital signature and encryption and guarantees confidentiality, integrity and non-repudiation in a more efficient way. Certificateless signcryption and proxy signcryption in identity-based cryptography were proposed for different applications. Most of these schemes are constructed by bilinear pairings from elliptic curves. However, some schemes were recently presented without pairings. In this paper, we present a certificateless proxy identity-based signcryption scheme without bilinear pairings, which is efficient and secure. © 2013 IEEE.

The lack of unified planning of E-government system in China leads to incapable interconnection among data and systems. In order to solve the problem, the technical characteristics like loose coupling, openness and long-term stability of service oriented architecture (SOA) were used to construct the safety flowing and emergency system of provincial highway and waterway, then Heilongjiang Province was taken as an example to construct the system through the oriented service workflow technology adapting to the distribution, heterogeneous, dynamic network environment of Heilongjiang government complicated application demand, and the transfer of the system from function management to business process management was realized in this paper. © 2015, Editorial Department of Transaction of Beijing Institute of Technology.

Under the framework of joint information embedding and lossy compression, an algorithm based on secret sharing and unequal protection is proposed. Comparing with arithmetic coding which compressed watermark length, our algorithm can dramatically reduce the amount of information bits embedded into video cover while guaranteeing watermarking authentication. Our algorithm not only improves compression efficiency but also adopts unequal protection strategy, thus improving watermark's robustness considerably. Furthermore, by making full use of dependency among neighbouring macroblocks, an adaptive watermarking algorithm based on motion vectors is proposed to effectively control motion vector's modification and guarantee video quality after watermarking. Experiments demonstrate that this algorithm not only keeps a small PSNR loss and satisfactory visual quality, but also shows resistance against frame-deletion attack.

The ideas and method about the realization of a scene simulation platform using Visual C++ and Direct SDK were introduced. The platform adopted the overall structure of "twin platform based on the shared core", and reusable framework and mechanism for the further development were founded. Three-tier design pattern of "function entity, collection management and user interface" improved code reusing. So the complexity of the problem was reduced, and the software development efficiency was improved. In this scene simulation platform, the management mechanism of extensible visual object was established, the display optimization of medium or small scene and rapid terrain-matching were realized, the functions of particle system-based special effects about rain, snow, smog and blast, etc, and creating, editing, playing and saving key frame animation were achieved. Finally, the applied example was researched.

The Authorization Management in Grid Systems has various structures. This paper proposes an identity-based authorization mechanism using IBE algorithm. Our scheme could satisfy the demands of the process from access requests committed by users to the authorized access control. The security level of the scheme is lower than the systems based-certificates. Because of its convenient, it is useful in light-weight grid systems.

As a research hotspot, microwave technology is employed to measure grains' moisture. Microwave devices based on various frequency bands appear in some measurement systems. These applications have no a theoretical foundation. This paper provides the principle of microwave technology used in moisture measurement. The factors, detection depth, horizontal and vertical resolutions, which are crucial to select the working frequency, are expounded. This paper also sets forth current application frequencies in moisture measurement systems. At the end, an advisable experiment framework is built to help select the frequency band preliminary for the moisture measurement. © (2013) Trans Tech Publications, Switzerland.

In the process measuring grain moisture with microwave, grain density is treated to be a factor that influences measuring result under utilization of traditional arithmetic. However, it is hard to measure grain density on line. Thus, the difficulty of measuring moisture content is rather higher. To improve the precision and to eliminate the influence of grain density, a density-independent arithmetic to calculate grain moisture with microwave was presented in the paper to import a density-independent operator. The arithmetic would not only develop the density-independent but also could be used as a standard compensation algorithm. It was suitable for on-line moisture detection on different categories of grain, further ensured the accuracy of test results. ©, 2015, Editorial Department, Chinese Cereals and Oils Association.

This paper provides an automatic barn-entering system for grains. Based on the technologies of microwave and PLC, the system may detect the grain moisture on line and control the directions of grain flows on conveyor. For the flows with moisture below the specified threshold, the grains may be made their way into the barn, otherwise rechannel the direction automatically and not permitted into the barn.Thus can avoid effectively grains' from going mouldy due to the high moisture content. © (2013) Trans Tech Publications, Switzerland.

In this article, a one-off seal function radio frequency identification (RFID) tag antenna with an omnidirectional radiation pattern when mounted on a liquid bottle is presented. The RFID tag antenna was pasted into the plastic open cap surface or inserted the clamping inner ring for further enhanced the quality of the liquid bottle seal function. Also, to using the RFID tag antenna for the different bottle neck radius, the radiation pattern and rectangular feeding loop was tilted to horizontal reference plane. The measured results show that these RFID tag antennas have good performance when attached onto the liquid bottle surfaces. © 2012 Wiley Periodicals, Inc.
