摘要:本文对两种与电网连接的能源系统(传统和可再生能源)进行了技术和经济分析。调查使用实验测量所需负载和天气数据(太阳辐照度和环境温度)进行,测得的日能耗为 5.1 kWh,太阳辐照度的年平均值为 4.6 kWh/m 2 /天。模拟过程使用 MATLAB 和 HOMER 软件以 1 分钟的时间步长分辨率完成。针对两种能源系统方案(i)光伏/电网和(ii)柴油/电网提出的经济优化目标考虑了基于伊拉克市场和法规的经济方面和组件价格。柴油发电机在农村地区非常受欢迎,设计为与光伏系统在同一时间(仅在白天)工作。年运行时间为 4380 小时/年,发电量约为 2349 kWh/年,燃料消耗为 1826 升/年。结果表明,情景 (i) 中的光伏系统可产生约 7895 千瓦时的电能,情景 (ii) 中的柴油发电机可产生约 2346 千瓦时的电能。此外,情景 (i) 的平准化净现值成本为 1079 美元,能源成本约为 0.035 美元/千瓦时,而情景 (ii) 的平准化净现值成本为 12,287 美元,能源成本为 0.598 美元/千瓦时。与柴油发电机相比,强烈建议使用太阳能,因为太阳能成本最低,并且能将能源输送到电网。此外,它每年可捕获约 5295 千克二氧化碳。

对 [设施的视觉研究区域 (VSA)] 的影响基本得以避免,设施在设施场地附近的可见性受到极大限制,并且 VSA 内部分或边缘可见性的区域主要限于大萨坎达加湖(申请人已经提议进行筛选以解决该问题)[,并且] 整个 VSA 中只有大约 0.80% 的预测可见性出现在小而孤立的区域,在大萨坎达加湖以外的区域,并且预计可见性会出现在参与土地所有者拥有的土地上。
可信度经济是一种批判性和分析性的启发式方法,本书以此为框架,探讨通过媒体文化进行的性别和种族可信度斗争。在二十一世纪,媒体对性暴力的描述因大众女权主义的可见度提高而得到强化,因此大众女权主义干预越来越多地通过媒体表达出来(Banet-Weiser,2018 年;Rottenberg,2018 年;Orgad 和 Gill,2022 年)。在关于大众女权主义和大众厌女症的文章中,Banet-Weiser(2018 年)认为,可见度经济是当代背景下的一种大众女权主义形象、表达和实践,这种形式在很大程度上是肯定性的和个人赋权的。在这种经济中,大众女权主义往往始于可见度,也终于可见度;可见度本身就是一种目的,而不是实现其他目的(如社会变革)的手段。事实上,在当代,存在着媒体学者赫尔曼·格雷(Herman Gray,2013)所说的“对可见性的煽动”。他问道,当最初产生认可必要性的社会结构发生转变时,这种对可见性的追求能产生什么结果。例如,当媒体对有色人种的报道越来越多,但日常生活中种族主义行为却越来越露骨时,可见性的提高意味着什么?因此,格雷问道,“对认可的渴望”是否会用对个人立场的认可取代结构性变化。可见性经济在#MeToo全球运动中以惊人的方式体现出来。依靠大众女权主义蓬勃发展的可见性回路,#MeToo
The Lisbon Treaty heralded new ambitions and advances in the formation of the European Union’s Common Foreign and Security Policy (CFSP).The treaty’s institutional changes smoothed cooperation, created an EU diplomatic service, and laid the groundwork for Permanent Structured Cooperation (PESCO).At the same time, these changes did not increase the EU’s visibility as a global actor.Common Security and Defense Policy (CSDP) missions have become more low profile; the High Representative position has not “stopped traffic”; and academ- ics, politicians, and the media have often criticized the CFSP for not living up to expectations.Since two women have held the post of High Representatives since Lisbon, sexism has most likely played a role in assessments of EU foreign and se- curity policy.,唐纳德·特朗普(Donald Trump)于2017年1月发誓
天气观测数据是准确预报天气的支柱,对航空界影响巨大。研究人员探索了使用 FAA 航空气象摄像机 (AvCams) 得出的能见度估计值来补充阿拉斯加传统观测的概念。研究中使用的能见度估计值由图像分析能见度估计 (VEIA) 算法生成,该算法识别 AvCam 图像中的边缘并将这些边缘的强度与合成的晴天图像进行比较。
