Journal: :Journal of Building Performance Simulation 2021

Courtyards are a passive strategy to improve the energy performance of buildings. However, accurate simulation courtyards’ thermodynamic in early design stage is still challenging, even though there has been an emergence new methods assess outdoor simulation. This paper tests novel workflow using Ladybug Tools that uses CFD for temperature and comfort courtyards suitable building design, compar...

The high-dimensional feature vectors of hyper spectral data often impose a high computational cost as well as the risk of “over fitting” when classification is performed. Therefore it is necessary to reduce the dimensionality through ways like feature selection. Currently, there are two kinds of feature selection methods: filter methods and wrapper methods. The form kind requires no feedback fr...

The identification of materials by measuring and analyzing their reflectance spectra has been an important method used in analytical chemistry for decades. Now, airborne and space-based imaging spectrometers give scientists the opportunity to detect materials and map their distributions across the landscape. With new satelliteborne sensor planned for the future, for example HYSPIRI (HYPerspectr...
