Performance Optimization of Luminescent Solar Concentrators under Several Shading Conditions

open access: yesEnergies, 2021
The need of clean energy is constantly increasing, and Building Integrated PhotoVoltaic (BIPV) technologies represent valuable assets to expand even further the photovoltaic market. Thanks to BIPVs. a new concept of local electric microgrid will probably

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.

An Experimental Investigation on Photovoltaic Array Power Output Affected by the Different Partial Shading Conditions

open access: yesEnergies, 2021
This paper presents an experimental investigation on photovoltaic array (PV array) power output affected by partial shading conditions (PSCs). An experiment setup of a PV array with a series configuration using 2 × 4 photovoltaic modules (PV modules) was

Effect of Sky Discretization for Shading Device Calculation on Building Energy Performance Simulations [PDF]

open access: yes, 2020
The calculation of sunlit surfaces in a building has always been a relevant aspect in building energy simulation programs. Due to the high computational cost, some programs use algorithms for shading calculation for certain solar positions after ...

Shades of grey [PDF]

open access: yesJournal of Medical Ethics, 2013
Last year I cared for Jamesi, an infant who had been born extremely prematurely. James was very sick in the first week or two of life, but had recovered and convalesced over the ensuing months. He was due to be discharged from hospital in the near future.

The Shading Cue in Context [PDF]

open access: yesi-Perception, 2010
The shading cue is supposed to be a major factor in monocular stereopsis. However, the hypothesis is hardly corroborated by available data. For instance, the conventional stimulus used in perception research, which involves a circular disk with monotonic luminance gradient on a uniform surround, is theoretically ‘explained’ by any quadric surface ...

Seed vigor, antioxidant metabolism and initial growth characteristics of red rice seedlings under different light intensities

open access: yesActa Botânica Brasílica, 2013
This work aimed to evaluate the effect that different intensities of light have on the physiological attributes of red rice seeds and seedlings. Before and after emergence, seedlings were exposed to light levels of 35%; 65% and 100% in a greenhouse.

Towards Grower-friendly Apple Crop Thinning by Tree Shading [PDF]

open access: yes, 2008
Light management with shading nets, which reduce sunlight by 74%, might be an alternative to chemicals commonly used for thinning on apple trees. To study the effect of shading on crop load and fruit quality, trials were conducted in field experiments ...
