    • 摘要: 立木胸径测量精准度直接影响胸高断面积、蓄积量的估算以及林地质量分析.现有测量方法都是将树干截面当作标准圆曲线来估测胸径;一些研究表明椭圆曲线或超椭圆曲线更能精准地反映树干和年轮的外形和生长情况.本研究利用自制的电子卡尺、传统围尺2种测量工具,选取8个树种,分别测量各树木的东西向、南北向、近似最大、近似最小胸径及胸高断面处的周长,并分析之间的差异性;研究了计算模型,将胸高断面分别当作标准圆、椭圆、超椭圆时与围尺测量值的接近程度以及对胸高断面积估算的影响.结果表明:1)超椭圆模型相比于标准圆、椭圆模型估算胸高断面积更加准确;2)东西向胸径比南北向胸径生长快的概率更高;3)对于卡尺,单株单次测量时选择东西方向的胸径,估算的胸高断面积更准确.

    • 摘要: 基于降低航空发动机轮盘孔结构孔边应力和装配的双重考虑,提出了1种超椭圆曲线轮盘螺栓孔均衡优化设计方法.在降低孔边应力的基础上,引入了异型度概念以表示孔轮廓形状变化幅度,针对孔边应力降低和异型度减小2个互相制约的优化目标,构建了1个均衡优化模型;结合Pareto最优解理论,采用多目标进化算法对轮盘超椭圆异型孔进行寻优,得到了超椭圆异型螺栓孔轮廓的最优解.结果表明:设计得到的超椭圆螺栓孔结构可以在保证可靠传力的同时,使孔边应力降低19%.与其他异型孔方案相比,该模型设计参数少,模型简洁,均衡优化所获得的超椭圆异型孔的设计稳健性较好.%An equilibrium optimization design method of the hyper-elliptic curves bolt hole of disk was proposed based on double consideration of reducing the hole edge stress of pore structure for aeroengine disks and assembly requirements. The concept of shape-variation-degree was defined to depict the degree of changes for hole profile on the basis of reducing the hole edge stress.The equilibrium optimization model consist of two competitive objectives was built,in which hole edge stress reduction and low shape-variation-degree were considered.Combined with Pareto optimal solution theory,multi-objective evolutionary algorithm was used to optimize hyper-elliptic non-circular hole of disk, and the optimal solution of hyper-elliptic non-circular bolt hole profile was obtained. The results show that the designed hyper-elliptic bolt holes structure can reduce the stress on the hole edge by 19% while ensuring reliable force transmission. Compared with other non-circular hole program,the model is concise and with less design parameters.In addition,the robustness of the design for equilibrium optimization hyper-elliptic non-circular hole is better.

Structured multisignature algorithms by reference are analyzed and improved in this paper. We present fast and efficient structured blind multisignature schemes based on hyperelliptic curves. The signature structure is expanded from two levels to three levels, so both sequential and broadcast are better inte-gration. And a variety of specific algorithms are given. Finally, the complexity and security of improved schemes are compared and analyzed. Comparing with current approaches, improved schemes reduce computation costs by (3n+2)T H+(273.8n+32.2)T M L. The results show that improved schemes have the advantages of low computation complexity, low computation time, high security and easy to implement.

    • 摘要: To improve the computational efficiency of bilinear pairing, the optimal variation of Weil pairing was constructed using the self-isomorphic and highly twisted hyper-elliptic curves.It was proved that the optimal variation of Weil was a bilinear pairing by a series of proof.A new Miller algorithm was constructed based on the optimized variants of Weil pairing, which reduced the computation of the loop length of the Miller algorithm significantly and simplified the final exponentiation calculation of the Miller algorithm.The results show that the constructed variation of Weil pairing is optimized on a number of highly twisted hyper-elliptic curves.%为提高双线性对的计算效率,利用自同构以及高度扭曲的超椭圆曲线构造优化变种的Weil对.通过对优化变种Weil对的一系列证明,验证其是一个双线性对;基于优化变种Weil对构造新的Miller算法,使计算双线性对的Miller算法的循环次数显著减少,简化Miller算法最后的幂运算.实验结果表明,在一些高度扭曲的超椭圆曲线上,构造变种的Weil对是最优化的.
