Traditionally, control strategies are applied to automate switchable electrochromic glazing systems (EC) save energy and provide comfort for occupants indoors. In addition, the plants’ minimum requirements consequences of active shading on supplemental artificial lighting plants should be considered when designers want embrace Biophilic design. This paper introduces a simulation workflow evalua...

In the last years, as fenestration and shading systems have become more complex and sophisticated, a great improvement of thermal and solar-optical performance has been required and as a consequence old methods of characterization have become inadequate. This evolution has yielded the introduction of new lumped parameters and the implementation of more sophisticated calculation models, which al...

Cotton-rapeseed or cotton-wheat double cropping systems are popular in the Yangtze River Valley and Yellow River Valley of China. Due to the competition of temperature and light resources during the growing season of double cropping system, cotton is generally late-germinating and late-maturing and has to suffer from the coupling of declining temperature and low light especially in the late gro...

Introduction Due to its exquisite sensitivity, breast MRI is becoming more and more popular for screening high-risk patients and for detecting high-grade ductal carcinoma in situ [1]. While 3T breast imaging yields clear benefits, such as increased SNR, allowing higher temporal or spatial resolution, it also comes with certain drawbacks. Most importantly, complaints about image shading and impr...

Abstract: As fuel prices increase and environmental issues become more serious due to the use of fossil fuels, as well as the expiration of fossil fuels, the researchers are looking to find alternative fossil fuels. Using renewable and green energy like solar energy using photovoltaic systems would be a convenient and cost-effective way. It is important to note that the efficiency of these cell...

this study aimed to determine the effects of different shading ratio and covers on “sultana seedless” table grape quality and storability. grapevines were covered at the veraison stage with 3 shading nets (0, 35, and 75% shading), which were then replaced with covering materials including polypropylene cross-stitch (pc), life pack (lp) and mogul (mg), just before harvest. harvested grapes in al...

Shading the greenhouses is necessary in summer to reduce the solar radiation load. This however generates a considerable amount of thermal radiation heat load that needs to be removed via cooling systems. This study aimed to evaluate the effect of different shading configurations on the solar and thermal radiation in a greenhouse. Nets at four different locations were employed to shade the roof...
