UNLABELLED Posterior cortical atrophy (PCA) is a rare focal neurodegenerative syndrome characterized by progressive visuoperceptual and visuospatial deficits, most often due to atypical Alzheimer's disease (AD). We applied insights from basic visual neuroscience to analyze 3D shape perception in humans affected by PCA. Thirteen PCA patients and 30 matched healthy controls participated, together...
This paper analyses the office demand connected to the use of different dynamic window and lighting control systems with the aim to optimize their usage aspects and characteristics from both visual and energy efficiency viewpoints. The approach is based on an improvement of the non-commercial hourly simulation program IENUS. Results are referred to a typical office located in Mediterranean clim...
Adaptive building envelope technologies can increase the energy efficiency of buildings. facades be controlled automatically and respond to environmental changes. There is no standard method for evaluating control strategies adaptive façade elements, particularly dynamic shadings. Therefore, ISO/DIS 52016–3 recommended different default compare use various variants. presents procedures consider...
Question: What are the physical and chemical effects of plant litter on annual grassland community composition, aboveground net primary production (ANPP), and density? Location: California annual grassland. Methods: We manipulated litter and light levels independently and in concert. Litter removal and litter addition treatments tested both the physical and chemical impacts of litter’s presence...
Light is an important resource for plant growth and development, crops need to change their physiological characteristics to different light environments. Fragaria ananassa Duch. cv. Toyonoka. is an important economic plant which is widely planted at home. A greenhouse experiment was conducted from April 2010 with different sun-shading treatment, 85% (CK), 60% (T1), 35% (T2) and 10% (T3). After...
During maize development and reproduction, shading stress is an important abiotic factor influencing grain yield. To elucidate the genetic basis of shading stress in maize, an F(2:3) population derived from two inbred lines, Zhong72 and 502, was used to evaluate the performance of six traits under shading treatment and full-light treatment at two locations. The results showed that shading treat...
this paper proposes a new configuration for solar energy conversion systems. one challenging issue of the photovoltaic (pv) systems is partial shading, and in this paper module integrated converters (mic) are used to overcome this problem in pv arrays. a few boost converters are employed as mics to mitigate the shading effect. furthermore, to reduce the cost and to increase the system performan...
