Simulation of Dimmer Circuit for Daylight Harvesting

Energy Procedia, 2012
AbstractIn this paper a fuzzy based dimmer circuit model for daylight harvesting is proposed. The model incorporates the variable daylight intensity and number of occupants in a room. The dimmer circuit controls the switching ON and OFF of LEDs (light emitting diode) in a room corresponding the daylight intensity and occupants while the required level ...

Talk to Your Data: An Agentic Artificial Intelligence‐Driven Decision‐Support Framework for Prosumer Energy Optimization and Recommendations

Advanced Intelligent Systems, EarlyView.
An agentic AI‐driven decision‐support framework for prosumers is proposed, integrating PV generation, load profiling, and multihorizon optimization within a four‐agent architecture. The approach significantly reduces grid dependence, enhances self‐sufficiency and prevents system oversizing.

Real‐time monitoring of root dielectric properties for assessing crop plant damage caused by foliar application of glyphosate

Applications in Plant Sciences, EarlyView.
Abstract Premise There is a knowledge gap regarding how foliar injury and restricted water uptake can be detected by measuring root dielectric response. This pot study nondestructively evaluated the efficiency of real‐time dielectric measurement to monitor the effects of glyphosate spraying.

High-resolution data-driven models of Daylight Redirection Components

Journal of Facade Design and Engineering, 2017
Daylight Redirecting Components (DRCs) guide daylight to zones with insufficient daylight exposure. They reduce energy demand for lighting, heating and cooling, and improve visual and thermal comfort. The data-driven model in Radiance is a means to model

The ORCA‐TWIN qCMOS Experiment I. Science Case and Commissioning at Calar Alto Observatory

Astronomische Nachrichten, EarlyView.
ABSTRACT We describe a pilot study to explore a new generation of fast and low noise CMOS image sensors for time domain astronomy, using two remote telescopes with a baseline of 1635 km. The experiment involves direct imaging with novel qCMOS image sensor technology that combines fast readout with sub‐electron readout noise.

A mosaic of microclimates: biodiversity outcomes and wildlife habitat potential in large‐scale solar facilities

Biological Reviews, EarlyView.
ABSTRACT The rapid global expansion of photovoltaic (PV) solar facilities, now comprising nearly 80% of the recent and projected growth of renewable electricity, represents one of the most significant land‐use changes of the 21st century. While PV facilities are critical for decarbonising energy systems, their large spatial footprint and infrastructure

Daylight simulations and tubular light guides

International Journal of Sustainable Energy, 2008
Indoor visual comfort is one of the leading requirements for building design. Results of computer daylight simulations serve to optimise the design process. Computer programs Ecotect and Radiance were used for the simulation of daylighting from tubular light guides of various diameters and lengths.
