Magnetic torquers are frequently used for the attitude control of small satellites in low-earth orbits (LEOs). In this paper, a linear time-varying model predictive control (LTV-MPC) approach for controlling a magnetically actuated nadir-pointing sa

c. Managing companies vertically and not separating two parts, film and digital
Kodak should have separated two parts, film and digital. But Kodak has stuck to manage all parts by one part. We think outsourcing is very extreme action but it could manage two parts with separating two parts.
As the above graph, Kodak seemed to misunderstand the time for digital to win film. It should have mai
