Altitude Adjustment of Empirical Models for Estimating Clear-Sky Solar Irradiance
Annals of West University of Timisoara: PhysicsThis research provides an innovative empirical model for solar irradiance estimation under clear sky conditions. The new model adjusts the estimates of G-EM clear-sky solar irradiance model (Goilean et al. AWUT-Physics 66, 2024, 241) with respect to site

An Edible Chitosan‐Based Acoustic Sensor for Sound‐Responsive Actuation in Edible Robots
Advanced Functional Materials, EarlyView.This study introduces an edible acoustic sensor for robotic food and edible robotics. Built from a chitosan piezoelectric film between gold electrodes, the sensor enables acoustic communication through ON/OFF keying. Integrated into an edible robot with pneumatically actuated arms and neck, it responds to high‐frequency tones.

A Stokesian model of areal clear‐sky direct radiation for mountainous terrain
Geophysical Research Letters, 1993 The global direct flux of clear‐sky incoming solar radiation over a given portion of terrain (e.g., the surface of a drainage basin) is modeled by using the Stokes' formula. Accordingly, line integration is substituted for surface integration to describe topographic variability.

Assessment of atmospheric emissivity models for clear-sky conditions with reanalysis data
Scientific Reports, 2022 Abstract Atmospheric longwave downward radiation ( L d ) is one of the significant components of net radiation (R n ), and it drives several essential ecosystem processes. L d

Advanced Functional Materials, EarlyView.A tubular electrowetting pump moves alternating droplets through a millimeter‐wide channel in discrete, reversible steps, functioning as a fluidic stepper motor. With no moving parts and electrodes insulated from the liquid, it delivers silent, accurate flow. Flexibility allows the pump to be woven directly into textiles for wearable, medical, and soft‐

Advanced Functional Materials, EarlyView.A fully polymeric two‐dimensional array of Dielectric Elastomers enables self‐sensing, cooperative actuation, and large‐stroke operation in a DE‐based autonomous conveyor. Based only on voltage and current measurements at actuator level, the system detects the presence of a ball and subsequently drives it toward a target position.
