随着人们休闲理念的多元化、休闲方式的多样化与休闲意识的提高,户外探险类纪录片逐渐受到了越来越多人的关注,这类纪录片给电视观众呈现了自然景观与人类行为,着重表现了人的自我挑战意识与主体意识,运用真实的影像资料,塑造出了具体的媒介事件,以此形成了其独特的美学表达特点。由美国探索频道播出的《荒野求生》作为探险类纪录片的代表之一,以其实用性和观赏性强的特征在全球赢得了大量的粉丝。该节目在赢得高收视率的同时也或多或少地带有“猎奇”传播的身影,然而探险并不等于“猎奇”,探险类纪录片始终要保持“猎奇”与教育的平衡。基于此,本文以《荒野求生》为例,分析探险类纪录片的美学特质与“猎奇”传播。 相似文献

In this article, we have derived tests based on the wild bootstrap that allow checking for differences between two irregular signals observed with additive noise where the latter consists of independent but not necessarily identically distributed random variables. The signals are first denoised by kernel estimates and then compared by looking at the integrated squared difference. The bound between accepting and rejecting the hypothesis of equal signals are determined by the wild bootstrap and numerically calculated by Monte Carlo simulation. The test is applied to all pairwise rows and columns of two images, which results in an algorithm that allows detection of defects and additional information on their location and shape surface inspection problems. The idea and theory of the test may be straightforwardly extended to the direct comparison of two images. This is computationally less expensive than doing all the row- and columnwise tests, but it provides less information. 相似文献

A ground-breaking European spacecraft will be first to explore Saturn's largest moon. On 25 December, the Huygens space probe begins its 20-day descent towards the surface of Titan. This article outlines the construction of the descent probe and instruments carried, gives details of the mission, and speculates on the conditions that might be found. 相似文献

Innovative cell structures for thin-film crystalline silicon solar cells should facilitate the achievement of relatively high performance from poor material quality. In particular, a design strategy based on heavily doped, multiple interleaved n- and p-type layers, in conjunction with the buried-contact solar cell approach, is presented. an example design is modelled to demonstrate the corresponding effective ‘radiation hardness’ and the ability to achieve high performance, even with poor minority carrier diffusion lengths expected at end-of-life (EOL) for a space cell. Results of modelling indicate that degradation in performance, sustained through typical space radiation damage, can be limited to approximately 5%. Using the same approach for terrestrial thin-film crystalline silicon cells fabricated from low-quality, low-cost material, eficiencies well above 16% should be feasible. 相似文献

复信号检测中门限估计的野值剔除 总被引:9,自引:3,他引:6
提出了一种适用于复数据检测门估计中野值剔除的kσ准则,并详细研究和比较了不同统计参量估计方法对野值剔除能力的影响。为准则的实际应用提供了分析依据。文中所导出的逐次判别剔除法可自适应野值数量较大范围的动态变化,此外,由于该准则仅要求上信号中基底噪声服从正态分布,对异常干扰和目标信号的统计特性无任何要求,因而适用性较强。 相似文献
