建筑与雕刻认同(identity)——雷姆·库哈斯和野口勇之比较

荷兰建筑家库哈斯的CCTV参赛方案,在初审获得评委一致通过,这是首次对这一方案做学术探讨的论文,文章把建筑家的雷姆·库哈斯和雕刻家的野口勇的作品进行比较,提出建筑与雕刻认同(identity)的观点,从建筑的雕塑身份、雕刻的身体性、空间美的发生以及环的多维性各点加以论述,此外,还将库哈斯30年的建筑生涯分为两个阶段,既热衷建筑类型的“前期库哈斯”,和趋于雕刻语言的“后期库哈斯”,并举例对脱“建筑”造型三步进行论证。最后得出当建筑向纯粹造型美术接近时,意味着一种向上的精神在发展的结论,而库哈斯的方案则是提出一种新思维。

Moderately large amplitude vibrations of uniform beams and square plates – proving intuitive formulas through rigorous analysis

Simple intuitive formulas, to calculate the large amplitude vibration frequencies, have been recently developed for the beams and square plates. The basis for development of these formulas is the master formula, obtained for the initially loaded structural members. These basic formulas, for the initially loaded beams and square plates, are modified to obtain the ratios of the nonlinear frequency (undergoing moderately large amplitude vibrations), for a given amplitude ratio, to the linear frequency parameters. Though, these intuitive formulas give a quick and accurate estimation for large amplitude vibrations, it is necessary to show that these formulas can be obtained through the rigorous formulation such as, the energy formulation. This is the main objective of the present study, where in it is demonstrated that the intuitive formulas, for the large amplitude vibrations of beams and square plates, are exactly the same with those derived by the rigorous energy formulation, for the s-s-s-s and c-c-c-c square plates, where s and c stand for the simply supported (hinged for beams) and clamped end/edge conditions. This study is further extended to beams and square plates with different boundary conditions, other than h-h and c-c boundary conditions for beams and s-s-s-s and c-c-c-c boundary conditions for square plates. The numerical results presented give the required confidence to the structural engineers and researchers, to use the simple intuitive formulas, whenever required.

Ecological risk assessment of urban and industrial systems: a review

Numerous ecological risk assessment methodologies have been developed over the last twenty years around the world for evaluating urban and industrial systems and installations, by both the organisations responsible for implementing regulations and the scientific community. Although these methodologies share the general principle underlying their use, they differ widely with respect to the approaches chosen and the resources employed to apply them. Also, they may even have different objectives: prior assessment as part of an impact study before building a new installation, or retrospective assessment, for example, in view to explaining the reasons for an impact recorded or for forecasting additional expected impacts.This article provides a synthesis of the different approaches used around the world for carrying out each of the major steps common to all ecological risk assessment methodologies. The advantages and limitations of these different options are discussed in order to provide elements for formulating any new methodology adapted to a given scenario. To conclude, perspectives for improving the tools required for these methodologies are proposed, and the research works to which priority should be given are identified.     

Meteorological Database for the United States

Abstract A meteorological database for the 48 contiguous states of the United States has been developed for use in indoor air pollution predictive models. The database contains predicted typical monthly meteorological statistics at the county level derived from hourly meteorological data from 208 (234 for precipitation) geographically distinct monitoring stations. Interpolation and extrapolation techniques were used to predict statistics for counties not containing a meteorological monitoring site. The LBNL database includes statistics for meteorological variables including dry-bulb temperature, dew-point temperature, barometric pressure, wind speed, wind direction, hours of precipitation, precipitation, and derived infiltration degree-days. The database consists of individual files of derived statistics for each weather variable and is potentially useful for indoor radon modeling as well as for other purposes. Each file contains data values for all 12 months and an aggregation of the 12 months up to a yearly statistic for all county centroids. A test was conducted to assess the quality of interpolated values. Examples showing the use of the database for mapping infiltration degree-days and an application of the database to a statistical correlation analysis attempting to find meteorological factors influencing indoor radon levels in the United States are discussed.     

微核试验数据的Poisson和负二项回归模型拟合效果比较

目的比较Poisson和负二项回归模型对微核试验数据（每1 000个双核淋巴细胞中具有微核的淋巴细胞数）的拟合效果,为微核试验数据的模型拟合提供依据。方法运用微核试验数据,拟合Poisson分布和负二项分布回归模型,采用对数似然函数、偏差统计量、Pearsonχ2统计量和聚集性指数等指标比较2种回归模型对实例数据的拟合效果。结果负二项回归模型对数似然函数值与自由度的比值（-2.51）大于Poisson回归模型（-3.52）;负二项回归模型拟合优度统计量-偏差统计量和Pearsonχ2统计量与对应的自由度比值（1.16和1.07）小于Poisson回归模型;聚集性指数的似然比检验（H0：k=0）显示,聚集性指数不等于0具有统计学意义（χ2=1 160.42,P〈0.001）。结论对于微核试验数据,拟合负二项回归模型要优于Poisson回归模型。

Two-degree-of-freedom inclined cable galloping—Part 1: General formulation and solution for perfectly tuned system

Galloping of inclined cables and other slender structures can occur in the critical Reynolds number range and/or in skew winds due to associated changes in the static force coefficients, even for cross-sections that are otherwise stable. A complete model of the quasi-steady aerodynamic forces leading to galloping has therefore been developed, for vibrations of any cylinder in two translatory degrees of freedom. It allows for arbitrary orientations of the flow velocity and the undamped vibration plane axes relative to the cylinder, and for variation of the force coefficients with Reynolds number and the relative angles. Analytical treatment of the eigenvalue problem has then led to an explicit expression for the minimum structural damping ratio required to prevent galloping for a perfectly tuned two-degree-of-freedom system, which it has been shown can differ significantly from the damping requirement for single-degree-of-freedom motion.
