Æ E Æ Å – Reshaping the Role of Træna Fishermen
This diploma project aims to strengthen the viability of Træna’s community by proposing an ocean research facility in the archipelago, enabling the next generation of local fishermen to collect oceanographic data while working at sea. The idea of the fisherman as oceanographer is inextricably linked to the architectural program on the island of ...

基于热电耦合方法的800 kV GIS隔离开关温度场仿真研究
温升是GIS设备的重要考核指标之一,温升过高会导致设备发热严重,进而影响GIS运行的可靠性。为准确分析GIS的发热和温升,基于有限元分析软件,通过热电耦合方法,建立800 kV GIS隔离开关损耗发热的求解模型,在综合考虑导体及外壳不同的散热系数、环境温度和材料电阻率随温度变化等多种因素的基础上,计算分析隔离开关的整体温度场分布。通过温升试验,对比主要部位温升的计算值和试验值,证明了该方法的准确性,为隔离开关的设计提供了参考。

Filling Uniformity of AgNPs in EMI Shielding Patch Regulated by Surface Morphology
ABSTRACT Silver nanoparticles (AgNPs) are extensively employed for electromagnetic interference (EMI) shielding owing to their remarkable conductivity, and are commonly incorporated into polymer matrices. Therefore, the uniformity of the AgNP distribution within the polymer matrix is a crucial factor that affects the EMI shielding performance.
