Study on the impact of photovoltaic electrochromic modular

In recent years, smart windows in buildings have been shown great potential and have been paid attention by researchers [[8], [9], [10]].Electrochromic and thermochromic windows are the two most promised types of smart windows [11].Thermochromic glass is relatively unstable in the building construction [12], and while electrochromic glass is relatively simple to

Telescope optical aberrations

The former are known as wavefront aberrations; the later as ray, or geometric (ray) aberrations. Either aberration form has its purpose. While the wavefront aberration form is more directly related to the physical fundamentals determining image quality, ray aberration form offers more convenient graphical interface for the initial evaluation of the quality level of optical systems.

Theoretical-experimental-simulation research on thermal

Energy use in buildings accounted for about 30% of global final energy consumption in 2021, contributing to about one-third of energy-related carbon emissions as the largest contributor [1] China, an even higher proportion is observed at about 45.5% in the building-related energy consumption and 50.9% in the building-related carbon emissions [2].
