简介：这篇论文起初构造冈瑟生成器的概率模型，；产量顺序的有限尺寸联合分发被介绍。结果证明产量顺序是一个独立人士；一致地散布了0,1随机的可变顺序。它给冈瑟生成器为什么能避免定期而不断被迫停的生成器的输出顺序的统计软弱的理论基础，；分析在产量顺序之间的巧合；输入冈瑟生成器的序列。这篇论文的结论将为设计者提供理论参考书；控制钟的发电机的分析器。

简介：在我们的电脑生活中，无论是登录系统还是进入邮箱都需要用密码。许多用户正是因为不懂得设置足够“强壮”而又“坚固”的密码，从导致密码轻易被人破解。怎样才能非常方便地设置出一个足够“强壮”而又“坚固”的密码呢？这就需要一款优秀的密码生成管理软件、笔者向大家推荐AdvancedPasswordGenerator。

简介：在一个thermoacoustic声波发电机的摆动的流动被描述。thermoacoustic声波发电机在thermoacoustic设备起一个重要作用。在工作液体的工作液体和栈，加速和减速之间的热交换并且粘滞在栈并且在回声试管影响的磨擦损失thermoacoustic声波生成器的性能。特别地，摆动的流动显著地影响在工作液体和栈之间的热交换机制。在压力和速度的时间的变化是在回声试管内的正弦曲线。流动就在试管插头后面形成一口摆动的喷气，并且在回声试管外面下游地远变得断断续续。0.63R的无限制的修正，也就是说尽管有在试管插头外面，被速度大小证实并且流动，摆动的流动特征下游地被维持的区域可视化。另外，他们几乎等于听觉的理论结果。关键词thermoacoustic现象-声波生成器-摆动的流动CLC数字TK11.4

简介：与密码学的快速的发展，安全协议和加密算法的力量过量地依靠随机数的质量。在许多密码学应用程序，更高的速度是要求的引用之一。新安全随机数生成程序体系结构被介绍。它的哲学建筑学与FPGA被实现，基于热噪音和线性反馈位移寄存器(LFSR)。热噪音initializesLFSRs并且被用作系统的打扰的来源保证生产随机数的unpredictability并且改进系统的安全力量。平行LFSR能与长时期和更高的速度生产伪随机数。建议建筑学罐头在密码学满足高质量、高的速度的要求。

简介：这份报纸论述方法由压电的生成器从沥青人行道收获机械精力。结果证明在沥青人行道的势能能每公里每小巷直到150kW/h。机械精力的部分能被压电的变换器收获。七个典型变换器的表演通过有限元素分析被检验。PZT堆的结果表演并且多层，在沥青人行道环境的钗钹和桥罐头工作。PZT堆积并且多层更高让精力变换评价。然而，如果这些变换器在人行道直接被嵌入，全部的收获精力是小的。一个原型人行道发电机用PZT堆积被开发增加收获精力。发电机能在交通拥挤下面从人行道收获超过50kW/h精力。816PZT堆积为一个发电机被推荐。圆形状被建议让PZT堆积减少应力的集中。并且多层的结构被推荐因为PZT堆发电机的电的潜力到减少。生成器能在沥青人行道作为传感器被扩大，它能被用来监视交通，人行道压力和温度。
