BACKGROUND AND AIMS Leaf mechanical properties, which are important to protect leaves against physical stresses, are thought to change with light and nutrient availabilities. This study aims to understand phenotypic changes of leaf mechanical properties with respect to dry mass allocation and anatomy. METHODS Leaf lamina strength (maximum force per unit area to fracture), toughness (work to f...

This paper aims to detect the existence of partial shading conditions on PV array and estimate vicinity global maximum power point for shaded modules based solely captured image modules. Detecting is comparing average pixel intensity each module find any mismatch in incident irradiance. Estimating irradiance level camera response function with help a reference module. Furthermore, after estimat...

Open circuit voltage of a silicon solar cell is around 0.6V. A solar module is constructed by connecting a number of cells in series to get a practically usable voltage. Partial shading of a Solar Photovoltaic Module (SPM) is one of the main causes of overheating of shaded cells and reduced energy yield of the module. The present work is a study of harmful effects of partial shading on the perf...

The effect of natural shading on photosynthetic capacity and chloroplast thylakoid membrane function was examined in soybean (Glycine max. cv Young) under field conditions using a randomized complete block design. Seedlings were thinned to 15 plants per square meter at 20 days after planting. Leaves destined to function in the shaded regions of the canopy were tagged during early expansion at 4...

Estimating transpiration as an individual component of canopy evapotranspiration using a theoretical approach is extremely useful it eliminates the complexity involved in partitioning evapotranspiration. A model to predict based on radiation intercepted at various levels leaf area index (LAI) was developed controlled environment pasture species, tall fescue (Festuca arundinacea var. Demeter). T...

This study explores the ability of WorldView-2 (WV-2) imagery for bamboo mapping in a mountainous region in Sichuan Province, China. A large area of this place is covered by shadows in the image, and only a few sampled points derived were useful. In order to identify bamboos based on sparse training data, the sample size was expanded according to the reflectance of multispectral bands selected ...

Abstract Microclimatic conditions affect seeds' survival, dormancy, and germination, which are determinants in vegetation succession recovery. The semiarid coastal scrublands of Yucatan, Mexico very important because the environmental services they provide thus, studies needed disturbed sites relation to seed viability microclimate. In this study, we characterized microclimate bank under Pithec...

Experiments in which a single target pattern is discriminated from multiple background distractors show that certain shaded, two-dimensional (2-D) stimuli consistent with a top-lit, polyhedral interpretation can be processed fast (< 80 msec) and in parallel. Unshaded line drawings of the same shapes, however, are processed serially. Strong pop-out asymmetries and control experiments involving s...
