Factorization Machine‐Based Active Learning for Functional Materials Design with Optimal Initial Data

Advanced Intelligent Discovery, EarlyView.
This work investigates the optimal initial data size for surrogate‐based active learning in functional material optimization. Using factorization machine (FM)‐based quadratic unconstrained binary optimization (QUBO) surrogates and averaged piecewise linear regression, we show that adequate initial data accelerates convergence, enhances efficiency, and ...

Solar irradiance variations

Eos, Transactions American Geophysical Union, 1983
The planned repair in orbit by NASA of the Solar Maximum Mission (SMM) in April 1984 provides an excellent opportunity for improved observations of the sun. In retrospect the solar‐terrestrial research community should have organized new programs before the 1980 launch of this satellite, but foresight is sometimes difficult to achieve.

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 ...

Solar irradiance reconstruction over the telescopic era using a revised photospheric magnetic field model

Astronomy & Astrophysics
The Sun is the primary source of energy for Earth and one of the main external drivers of its climate. Solar irradiance – the radiative power emitted by the Sun and received at 1 AU – varies on all observable timescales. It is measured as the total solar

PRECISE MEASUREMENTS OF SOLAR BEAM IRRADIANCE THROUGH IMPROVED SENSOR CALIBRATION

, 2009
Solar beam irradiance is measured for solar energy applications due to two reasons: to determine the available amount of the solar resource and energy yield at sites selected for an installation or to evaluate efficiency and proper operation of a ...

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 ...

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

Maximum power point tracking enhancement for PV in microgrids systems using dual artificial neural networks to estimate solar irradiance and temperature

Results in Engineering
This paper presents an artificial neural network-based maximum power point tracking (MPPT) method. Where dual ANNs predict solar irradiance and temperature. Next, an adaptive computation block determines the maximum power point (MPP).

Ozone Depletion and Global Warming

, 2006
This thesis examines global warming and the possible contribution that ozone depletion provides to this warming. An examination is performed to determine the extent of any warming/cooling events within the Earth-atmosphere system.
