(PhysOrg.com) -- Three-dimensional TV is now closer than ever to becoming a reality for consumers, and the latest research is investigating the full extent of 3D TV’s possibilities. In a recent study, researchers at the ...
We often encounter nonlinear dynamical systems that behave unpredictably, such as the Earth's climate and the stock market. To analyze them, measurements taken over time are used to reconstruct the state of the system. However, ...
