本文研究了性质不确定的外黏弹性阻尼器控制结构的抗震性能.耗能器件的行为由分数阶本构律描述,其中分数阶导数阶和阻尼系数都被建模为具有指定下界和上界的区间变量.地震动加速度是一个零均值平稳高斯随机过程.在这些假设下,被控结构的运动由一组区间分数阶微分方程控制.所有响应量均由区间零均值平稳高斯随机过程描述,其功率谱密度函数依赖于黏弹性器件的区间参数,在频域上完全表征.通过将经典的首通道问题扩展到区间框架进行可靠性分析.用一种有效的近似方法计算了区间值可靠度函数的边界.本文给出了基于文献中实验结果定义的间隔特性的黏弹性器件的实例研究.

Bioinspired computing is a research framework that solves computer science problems based on the principles of biology and the natural world, including DNA and membrane computing. Membrane computing(MC), an active subfield of bioinspired computing based on the biological cell structure,emerged as an unconventional computational paradigm and has generated an extensive fundamental research scope in theoretical computer science [1].

Objectives: To use a novel in vitro model of three-dimensional(3D) neurosphere cultures to assess neurotoxic or neuroprotective effects with harmane as a model ***: A reproducible model of 3D spheroids was developed from embryonic mouse cortical neurons,using molded agarose micro-wells;this method seems particularly practical as it is customizable and widely available and does not require specific cell treatments or assay components different from 2D cultures, allowing for the easy transposition of routine protocols. To assess the neurotoxic effects of harmane, a resazurin assay was performed to measure cell viability, and a highly sensitive fluorometric method, based on the oxidation of dichlorodihydrofluorescein, was applied to measure eventually induced reactive oxygen species(ROS) after exposure to harmane at increasing concentrations of 50 100,and 250 μ***: Hydrogel microwells facilitated the assembly of spheroids containing neurons and glial cells into a complex 3D structure and prevented the agglomeration of spheroids. Exposure to harmane induced cytotoxicity in 3D neural spheroids, which was correlated with harmane concentrations, with a 27%reduction in viability at 250 μm. Harmane that did not induce significant levels of oxidative stress was detected for all tested ***: This 3D neurosphere model mimics a neuronal microenvironment, allowing a fine study of neurodegenerative disorders and the effects of chemicals on the brain. This model opens novel opportunities, not only from a pathogenetic point of view but also from a therapeutic perspective.

The ability to accurately characterize projects novel project characteristic is developed characteristic, called project regularity, is essential to good project management. Therefore, a reflects the value accrue within a project. This expressed in terms of the newly introduced regular/irregular-indicator RI. The widely accepted management system of earned value management （EVM） forms the basis for evaluation of the new characteristic. More concretely, the influence of project regularity on EVMforecasting accuracy is assessed, and is shown to be significant for both time and cost forecasting. Moreover, this effect appears to be stronger than that of the widely used characteristic of project seriality expressed by the serial/parallel-indicator SP. Therefore, project regularity could also be useful as an input parameter for project network generators. Furthermore, the introduction of project regularity can provide project managers with a more accurate indication of the time and cost forecasting accuracy that is to be expected for a certain project and, correspondingly, of how a project should be built up in order to obtain more reliable forecasts during project control.
