摘要：extreme water level is an important consideration when designing coastal protection structures. However, frequency analysis recommended by standard codes only considers the annual maximum water level, whereas water levels should actually be regarded as a combination of astronomical tide and storm surge. The two impacting factors are both random variables, and this paper discusses their dependency structures and proposes a new joint probability method to determine extreme design water levels. The lognormal, Gumbel, Weibull, Pearson type 3, traditional maximum entropy, and modified maximum entropy distributions are applied to fit univariate data of astronomical tides and storm surges separately, and the bivariate normal, Gumbel-Hougaard, Frank and Clayton copulas are then utilized to construct their joint probability distributions. To ensure that the new design method is suitable for use with typhoon data, the annual occurrence frequency of typhoon processes is considered and corresponding bivariate compound probability distributions are proposed. Based on maximum water level data obtained from Hengmen hydrological station in the Pearl River Basin, China, these probability models are applied to obtain designs for extreme water levels using the largest sum of the astronomical tide and storm surge obtained under fixed joint return periods. These design values provide an improved approach for determining the necessary height of coastal and offshore structures.

摘要：The high-resolution climate model Providing REgional Climates for Impacts Studies (PRECIS) was used to project the changes in futureextreme precipitation and temperature over the Koshi River Basin for use in impact assessments. Three outputs of the Quantifying Uncertaintiesin Model Prediction (QUMP) simulations using the Hadley Centre Couple Model (HadCM3) based on the IPCC SRES A1B emission scenario were used to project the future climate. The projections were analysed for three time slices, 2011e2040 (near future), 2041e2070 (mid-century), and 2071e2098 (distant future). The results show an increase in the future frequency and intensity of climate extremes events such as dry days, consecutive dry days, and very wet days (95th percentile), with greater increases over the southern plains than in the mountainous area to the north. A significant decrease in moderate rainfall days (75th percentile) is projected over the middle (high) mountain and trans-Himalaya areas. Increases are projected in both the extreme maximum and extreme minimum temperature, with a slightly higher rate in minimum temperature. The number of warm days is projected to increase throughout the basin, with more rapid rates in the trans-Himalayan and middle mountain areas than in the plains. Warm nights are also projected to increase, especially in the southern plains. A decrease is projected in cold days and cold nights indicating overall warming throughout the basin.

摘要：2015年3月13日下午，Estelon（爱诗特浓）团队（Alfred＆Partners OU公司）联手爱沙尼亚驻中国大使馆、汕头泽森音响有限公司、联电国际智能化（北京）有限公司在北京爱沙尼亚大使馆举办了2015 Estelon（爱诗特浓）extreme旗舰音箱发布会。

摘要：当我们谈到顶级的现代扬声器系统（即音箱），我们会说到什么呢7毋庸置疑的声音表现,让人过目难忘的外观和精致的加工工艺,当然还有让人昨舌的价格。在15年前，价格超过30万元的音箱已经是罕有，超过50万元的一般只能在广告上看到，而现在呢？

摘要：在2006年11月8日；NVIDIA发布了基于DirectX10的G80和为下一代桌面主板设计的nForce 680i芯片组。G80我们已经在发布的第一时间为大家送上了详细的介绍和测试情况，但由于基于nForce680i的产品到目前还没有大规模上市，所以我们没能在前几期进行测丛!至塾；砖2007年的春节前．华硕的Striker extreme终于来到了我们评测室；虽然是姗姗来迟，但距离发布已经有三个月，相信在这段时间里．NVIDIA和华硕都已经利用充分的时间将这款目前性能最强的主板原有的小小bug修复；所以我们可以在测试中获得更好的成绩。
