Assessing the Feasibility of Wearable Devices for Physiological Monitoring and Heat Risk Prediction in Outdoor Agricultural Workers

American Journal of Industrial Medicine, EarlyView.
ABSTRACT Background Outdoor agricultural workers experience significant heat exposure, yet few studies have evaluated whether wearable sensors can reliably measure continuous physiological responses in real field conditions. This pilot study examined the feasibility and predictive utility of core temperature, hydration, heart rate, and movement data ...

Estimation of Solar UV Irradiance Under Clear-Sky Conditions from Broadband Radiometric Measurements

Atmosphere
It is well known that broadband solar irradiance is measured with a much higher spatial density than ultraviolet (UV) solar irradiance. Building on this, this study proposes a new model for estimating clear-sky global UV solar irradiance based on ...

Experimental Study of the Spectral and Angular Solar Irradiance

2019 IEEE 46th Photovoltaic Specialists Conference (PVSC), 2019
We have developed an experimental procedure to measure spectro-angular solar irradiance for accurate prediction and optimization of bifacial solar power plants. Our measurements show strong spectro-angular irradiance variations dependent on location, surroundings and cloud coverage.

Passive Moisture‐Driven Cooling via Low‐Cost and Shape‐Stabilized Hygroscopic Composite Foam for High‐Power Electronics

Carbon Energy, EarlyView.
A passive moisture‐driven cooling strategy is proposed to effectively manage the heat in high‐power electronic and energy devices, reducing the chip temperature by 37°C, the lithium‐ion battery temperature by 26°C, and the photovoltaic panel temperature by 15°C, thereby to enhance the battery safety and PV efficiency with a low‐cost, shape‐stabilized ...

Modeling decadal and centennial solar UV irradiance changes

Reconstructions of solar spectral irradiance—especially in the ultraviolet (UV) range—are crucial for understanding Earth’s climate system. Although total solar irradiance (TSI) has been thoroughly investigated, the spectral composition of solar ...
