New constraints on data-closeness and needle map consistency for shape-from-shading [PDF]

open access: yes, 1999
This paper makes two contributions to the problem of needle-map recovery using shape-from-shading. First, we provide a geometric update procedure which allows the image irradiance equation to be satisfied as a hard constraint.

Optimal design of photovoltaic shading systems for multi-story buildings [PDF]

open access: yes, 2019
This study provides new insights into the comprehensive energy and economic performances of photovoltaic shading systems (PVSS) in multi-story buildings. A numerical shading model was developed to evaluate the shading effect from an upper PVSS row on its
