Mechatronics Application to Solar Tracking
, 2011 The purpose of this was to design and implement a two-axis solar tracking system utilizing the National Instruments C-Rio real time controller. In order to accomplish this a prototype was modeled in CAD. This prototype used two 12 V DC motors to change a

A Study of Solar Rotation and Differential Rotation
Journal of Applied Mathematics and Physics, 2023 openaire +1 more source
The Astrophysical Journal LettersThe helioseismically observed solar tachocline is a thin internal boundary layer of shear that separates the rigidly rotating solar radiative zone from the differentially rotating convective zone and is believed to play a central role in the 22-yr solar ...

Toroidal Magnetic Flux Budget in Mean-field Dynamo Model of Solar Cycles 23 and 24
The Astrophysical JournalWe study the toroidal magnetic flux budget of the axisymmetric part of a data-driven 3D mean-field dynamo model of Solar Cycles 23 and 24. The model simulates the global solar dynamo that includes the effects of the formation and evolution of bipolar ...

Emerging Materials and Future Strategies for Solid Oxide Electrochemical Cells
Advanced Energy Materials, EarlyView.Solid oxide electrochemical cells operate under strongly coupled electrochemical and thermodynamic conditions, where performance is constrained by interactions among crystal structure, defect chemistry, and interfacial evolution. This review, based on a structure‐defect‐property‐durability framework, reveals the roles of lattice symmetry and defect ...
