摘要：通过Bass扩散模型分析并提出了以平台收入最大化为目标的电子书定价策略,仿真分析了不同阶段热度效应、广告植入量及用户体验质量等关键因素对最优决策的影响机制。研究表明:在发展初期,平台应采用免费主导策略以快速扩大用户规模,而在发展成熟期则转变为付费主导策略以获取最大利润;广告植入量将影响用户体验和平台收入水平,且与用户类型相关。建议:实践中应关注用户的广告厌恶因子,当付费用户和免费用户体验质量间的差异较大时,热度较高的电子书应设置较低的定价和广告量。

摘要：拉丁超立方设计是最常用的计算机试验设计方法之一,针对现有拉丁超立方设计方法采样一次性且难以兼顾设计的空间均匀性和计算效率的问题,提出了一种演化排列拉丁超立方试验设计方法。通过对小样本设计的演化、排列信息继承和扩充等操作,以较小的计算量实现了样本的扩充与优化。此外,所提方法可以兼顾现有样本和新增采样点之间的关系,实现样本的序列扩充,这在实际近似建模过程中十分方便。通过多组数值试验,验证了本文方法在空间均匀性和计算效率等方面的优越性。

摘要：为准确聚类海量云数据,提出一种基于密度峰值的海量云数据模糊聚类算法。将含有噪声的云数据采用BP神经网络分离,将输出的噪声利用奇异值分解重构,获取联合算法输出的噪声,将带有噪声的云数据和输出噪声相减,得到去噪后的云数据。将密度峰值和优化后的模糊聚类算法相结合,自适应形成初始聚类中心,确定聚类数量,最终实现海量云数据模糊聚类。实验结果表明:本文算法获取的聚类效果和聚类效率明显优于其他算法。

摘要：Superplasticizers are widely used to reduce the pipe flow resistance of cemented paste backfill(CPB), which is characterised by high concentration and high yield stress. This study aimed to assess the time-dependent rheological properties of CPB containing superplasticizer, with special focus on static yield stress and thixotropy. The results indicate that with the increase of the superplasticizer dosage, the static yield stress, dynamic yield stress and thixotropy of CPB decreased significantly, while the plastic viscosity decreased slightly. The curing time has a significant effect on the static yield stress, dynamic yield stress and thixotropy of CPB containing superplasticizer, which increase by 46.6%-87.1%,15.2%-35.6% and 79.4%-138.2%, respectively, within 2 h. The static yield stress, dynamic yield stress and thixotropy of CPB without superplasticizer only increase by 4.9%, 6.3% and 16.1%, respectively, within 2 h. The curing time has a significant influence on the plastic viscosity of CPB regardless of superplasticizer addition, the plastic viscosity increases by 13.2%-19.7% within 2 h. Regardless of superplasticizer dosage, plotting of both static yield stress and dynamic yield stress versus thixotropy produces clearly linear curves. The findings of this study are conducive to the design of pipe transportation of CPB containing superplasticizer.

摘要：研究含有状态时延的严反馈非线性系统的跟踪控制问题,充分考虑时延的时变性和任意性以及系统的未知动力学特性.为解决该问题,取代参数辨识、函数逼近、增益调节、指令滤波等常规技术,提出基于导向函数的预设性能控制方法,移除了控制器设计对于系统非线性、控制方向和虚拟控制信号导数等信息的依赖.并且,摆脱基于李雅普诺夫−克拉索夫斯基泛函或拉祖米欣函数的稳定性分析框架,采用基于反证法的受限分析理论,移除性能分析对于已知的时延上界、部分已知的时延非线性函数和时延导数小于1等常见约束.因此,形成无模型、低复杂度、高性能控制方法,将跟踪误差限制于设计者预先选取的性能包络线内,确保系统输出以预先设定的速度和精度跟踪上时变的设定值.最后,以具有延迟回收流的两级化学反应器为对象开展对比仿真,实验结果验证了所提方法的有效性和优越性.
