Considering the problem of quantitative evaluation for qualitative survivability data and indexes of network information systems, the proposed method gives a multi-level survivability evaluation framework VERVAIN based on cloud model theory and AHP method.The algorithm builts a multi-level evaluation indexes system and compute the weight of each in

When multiple active power filters (APF) are incorporated into the regional distribution network, there are complex negative interaction effects among the control circuits, resulting in the decline of APF compensation performance and harm to the stability of power system.Firstly, a multi-APF grid-connected mathematical model under the condition of

This research focuses on the diesel and diesel/oil mixed fuel combustion particles as the research object and analyzes the characteristics of the two kinds of fuel oil under different parameters.The characteristics of the combustion particulate matter in the DPF discharge of the two fuels before and after carrying out TEM imaging of the sample part

In this article, temperature and moisture distributions in a finite-length hollow cylinder made of functionally graded material (FGM) under transient coupled hygrothermal condition was presented.The coupled equations of heat conduction and moisture diffusion were solved employing the Fourier series expansion method along the longitudinal direction,

Cultural heritage represents the link between past and present civilizations, contributing to the right appreciation of the present-day by understanding the historical evolution of different human communities that are shaping our world.Preservation of the cultural heritage and mitigating potential risks on invaluable artifacts or objectives is key
