Sky type classification in Harbin during winter
Journal of Asian Architecture and Building Engineering, 2020 Sky type classification is a significant element in daylight simulation. As a “winter city”, the daylight climate of Harbin is distinctive, and there is therefore a particular need to determine the most appropriate sky models to establish sky luminance ...

The clear‐sky index to separate clear‐sky from cloudy‐sky situations in climate research
Geophysical Research Letters, 2000 Accurate surface radiation fluxes are required to quantify atmosphere‐surface energy exchanges. In climate research, detailed investigations of the influence of diverse atmospheric conditions on radiative fluxes ask for a well‐defined distinction between clear‐sky and cloudy‐sky situations.

Advanced Materials, EarlyView.ABSTRACT The accelerating expansion of data‐centric technologies is sharply increasing the energy burden of information storage, placing unprecedented pressure on the efficiency of magnetic switching. Conventional field‐driven reversal, once the foundation of magnetic memory, has become impractical in modern architectures due to its high energy cost ...

Resonant Domain Wall Dynamics in a Three‐Dimensional Magnetic Nano Double Helix
Advanced Materials, EarlyView.3D magnetic nanostructures promise exciting possibilities for magnetization dynamics. However, experimental realizations remain scarce. In nanoprinted cobalt double helices, time‐resolved X‐ray microscopy reveals harmonic domain wall dynamics. Simulations identify the mode and additional higher‐frequency resonances, revealing a rich dynamic landscape ...

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
