This thesis is concerned chiefly with the study and research of design principle , security , randomness and hardware implementation of the rijndael algorithm 本文着重对rijndael算法的设计原理、安全性能、统计性能以及硬件实现进行探讨和研究。
It considers structures as a whole , and studies the randomness of the structures in the future . it is more rational than the traditional way 它将结构作为一个整体考虑,并且研究了结构在未来工作期间表现的随机性,比传统的结构优化设计更为合理。
For such reason , the long - term behavior of system exhibit chaos and the time & space average of system shows typically randomness 由于这种不稳定性,系统的长时间行为会显示出某种混乱性,对时间或相空间的粗粒平均将呈现典型的随机行为(或显示随机性质) 。
As randomness , nonlinearity , and difficulty to setup an exact mathematics mode , using intelligent control methods to elevator group is a necessary 由于电梯群控系统具有随机性、非线性,并且难以建立精确的数学模型,运用智能控制的方法成为可能和可行。
However , the interest rate is also random . with the development of actuarial studies , interest randomness in life insurance has received con - siderable attention 然而事实上,利息率具有随机性。随着精算理论研究的深入,利率随机性的研究逐步受到重视。
The calculation example shows that the method can describes the randomness of concrete material satisfactorily and coinsides with the laws of test and engineering 算例表明,本方法较好地描述了混凝土材料性质的随机性,计算结果与模型试验和工程实际规律吻合。
The hydrologic processes have been described by regular methods of internal determinacy or external randomness or both of them for a long time 长期以来,一直采用传统的确定性或随机性或两者结合的方法来描述水文过程,揭示水文系统的内在确定性规律和外在随机性规律。
People have reallized that the risk accrued by interest randomness may be very large to insurance organizations ( insurance company and social insurance development ) 人们开始注意到,对保险组织者(保险公司和社会保险部门)而言,由利息随机性产生的风险可能是相当大的。
Shape optimization of structure based on the definite finite element had not considered the design variable ' s randomness ; it cannot re - fleet the real condition of structure 摘要基于确定性有限元分析的结构形状优化没有考虑设计变量的随机性,不能够反映结构的真实状况。
On the basis of randomness analysis of traffic demand and supply and the reliability analysis of network , the concept of unblocked reliability was presented 摘要畅通可靠度是在考虑交通供给和交通需求的随机变化特性的基础上,借鉴网络可靠性分析方法,提出的概率型指标。
(thermodynamics) a thermodynamic quantity representing the amount of energy in a system that is no longer available for doing mechanical work; "entropy increases as matter and energy in the universe degrade to an ultimate state of inert uniformity" 同义词:entropy, S,
