确定单分子化学反应过渡态近似构型的两点渐近法

本文提出了一种求单分子化学反应过渡态近似构型的方法。在反应位能面上定义一个拟设反应方向,沿此方向以一定间距求出能量值,并找出其中的能量极大点S。在S两侧选a_1和b_1两点,分别求其能量梯度值。沿能量梯度的负方向将a_1,b_1分别移至α_1和β_1;则α_1,β_1比a_1,b_1更接近过渡态。多次重复以上过程直到两点几乎重合,可以得到过渡态的近似几何构型。按此方案利用MINDO/3程序找HCN, FCN重排反应及甲酸异构化反应的过渡态近似构型,得到了较好的结果。     

New multivariate-based certificateless hybrid signcryption scheme for multi-recipient

With the development of quantum computer,multivariate public key cryptography withstanding quantum attack has became one of the research focus.The existed signcryption schemes from discrete logarithm and bilinear paring are facing the serious threats.Based on multivariate public key cryptography,a new certificateless multi-receiver hybrid signcryption scheme has been proposed.The proposal reduced the cipher text and could handle arbitrary length messages by employing randomness reusing and hybrid encryption,as well as keeping security.In the random oracle model,the scheme’s confidentiality could withstand the IND-CCA2 adversary and its unforgeability could withstand the UF-CMA adversary under the hardness of multivariate quadratic(MQ)problem and isomorphism of polynomials(IP)assumption.It has less computation overhead and higher transmission efficiency than others.It reduced 33%cipher data compared with the existed similar scheme.     

An Efficient and Practical Public Key Cryptosystem with CCA-Security on Standard Model

Chosen Ciphertext Attack （CCA） security on the standard model is widely accepted as the standard security notion for the public key cryptosystem. The existing CCA-secure public key cryptosystems on the standard model are expensive in terms of efficiency and practicality. In this paper, an efficient and practical public key cryptosystem is presented over the group of signed quadratic residues. It is provably secure against CCA on the standard model. Furthermore, public verifiability for this scheme is also realized in the way that projects the verification privacy key into public key on trapdoor pretending. It will be useful to devise efficient CCA-secure threshold and proxy re-encryption schemes on the standard model.     

1/3焦煤和肥煤参与配煤炼焦的比较

对1/3焦煤和肥煤进行煤质分析,并对其单种煤的成焦光学组织、焦炭强度及参与配煤后对焦炭性能的影响进行比较。结果表明,当肥煤的胶质体质量一般或较差时,在配合煤中的作用与优质1/3焦煤相当,生产中两种煤可进行互换,但应针对调节焦炭冷、热性能的不同需要确定不同的配比。     

自动化集装箱码头AGV调度与换电双层模型求解

为降低自动化集装箱码头AGV换电问题对码头整体作业效率的影响,首先分析了AGV调度和换电的相互影响和内在联系.其次考虑AGV耗电差异和换电阈值等约束以最小化最终完工时间为目标建立AGV调度模型(上层模型),考虑换电站数量和排队等约束以最小化换电总时间为目标建立AGV换电模型(下层模型),并针对两者之间的双层耦合关系,设计换电需求和换电方案为公用变量进行解耦.最后使用自动化集装箱码头实际作业参数设计算例,分别采用GAMS求解器和遗传算法循环迭代求解.算例结果表明,双层耦合模型合理地决策了AGV调度和换电问题,换电排队时间控制在4 min之内,降低了AGV换电总时间和最终完工时间,提升了AGV利用率.
