Hydrodynamic characteristics of double permeable breakwater under regular waves

The wave transmission, reflection, and energy dissipation of the double vertical wall with permeable lower part (horizontal slots) were experimentally and theoretically studied under normal regular waves. The effect of different wave and structural parameters on the hydrodynamic characteristics was investigated e.g. the wave length, the upper part drafts, the lower part porosities, and the space between the double walls. Also, the theoretical model based on an EigenFunction Expansion Method was developed to study the hydrodynamic breakwater performance. In order to examine the validity of the theoretical model, the theoretical results were compared with the present experimental results. Comparison between experiments and predictions showed that theoretical model provides a good estimate to the wave transmission, reflection, and energy dissipation coefficients when the friction factor f = 3. The hydrodynamic efficiency of the proposed breakwater is strongly affected by changing the following: (1) The two upper part drafts together, (2) The upper part draft of the first barrier, (3) The two lower part porosities together, (4) The lower part porosity of the first barrier.

伊犁地区公路边坡不同植物组合的水土保持效应研究——以S242 线巩留至尼勒克公路建设为例

为了更好地治理伊犁地区公路建设中的水土流失问题,保护该地区的生态环境,依托S242线巩留至尼勒克公路路基边坡开展试验,通过土壤机械组成、土壤容重、土壤孔隙度、土壤抗冲性等指标对比分析了4 种植物组合的水土保持效应。结果表明,经过1年试验,植物组合下的土壤质地由壤土转变为粉砂质壤土,土壤容重小幅减小,土壤孔隙度增加,土壤的抗冲性和抗蚀性得以提升,使得其土壤侵蚀量较裸坡对照小区明显减小,其中丙植物组合小区的土壤侵蚀量最小,水土保持效应相对最好。     

Inclusionary housing in the California coastal zone

Abstract

This article evaluates the performance of the California Coastal Commission's inclusionary housing program by examining: (1) the scope of the housing regulations, (2) initial permit decisions on residential projects, (3) the disposition of these permits overtime, and (4) the composition of completed projects and a best‐case projection of possible project completions. Using a case study of Southern California, factors affecting program success are discussed, including the effects of the various regulations, the availability of project subsidies, local government permit policies, and housing market fluctuations. The authors conclude that such state regulatory programs cannot be expected to succeed in urbanized coastal areas without incentives for developers and augmented state agency authority, superseding local land use controls.     

关于信息理论中的一个猜想

物质的可知性要求物质的相互作用的信息必然由光子携带,而且必然传递给周围的环境。在此观点的基础上文献给出了信息理论上的一个基本猜想：任何事件与其观察者之间都会存在至少一个单光子的信道。
