The development of near-surface remote sensing requires the accurate extraction of leaf area index (LAI) from networked digital cameras under all illumination conditions. The widely used directional gap fraction model is more suitable for overcast conditions due to the difficulty to discriminate the shaded foliage from the shadowed parts of images acquired on sunny days. In this study, a new LA...

The performance of Concentrating Photovoltaic and Thermal (CPV/T) systems is also linked to climatic conditions. In this paper, the main purpose determine energy economic a line-focus CPV/T system used for residential user, considering three cities with different weather conditions: Amsterdam (The Netherlands), Marrakech (Morocco), Salerno (Italy). A modular configuration system, concentration ...

Accurate prediction of collector performance is important for optimal planning solar thermal systems. Here, a novel method combining clustering data with artificial neural network (ANN) model presented. A all-glass straight-through tube employed as reference technology. In the present approach, experimental was first collected during different weather conditions (sunny, cloudy, rainy days) subj...

What are relativistic jets like within a million Schwarzschild radii of the accreting black hole that powers them? A meeting in Granada, Spain in June 2013, organized by José L. Gómez and his conspirators brought together observers and theorists to survey the current state of observational data and efforts to interpret them. This conference summary reviews the results, insights, arguments, conf...

Contents As part of the global development of telecommunications networks, Base Transceiver Stations (BTS) are also frequently constructed in Off-Grid locations or Bad-Grid locations. The Sunny Island is very well suited to ensure the electricity supply to a BTS even in such locations due to its flexibility and robustness. Off-Grid systems with Sunny Island are distinguished by the following fe...
