This volume develops a systematic study of time-dependent control processes. The basic problem of null controllability of linear systems is first considered. Using methods of ergodic theory and topological dynamics, general local null controllability criteria are given. Then the subtle question of global null controllability is studied. Next, the random linear feedback and stabilization problem is posed and solved. Using concepts of exponential dichotomy and rotation number for linear Hamiltonian systems, a solution of the Riccati equation is obtained which has extremely good robustness...

At the age of seventeen, Paul Garrett began to time travel. He unraveled a struggle between good and evil that pitted a demonic spirit of desolation against an angelic being of light. Paul got caught in the middle, and the evil Abomination made this struggle a personal one by murdering Paul's family. When Paul seeks help, the angelic Guardian sends Paul on a quest through time to find the way to kill the demon. During the time of the ancient cataclysmic flood of Noah, Paul discovers a way to defeat the demon, which comes at a high price. Innocent blood has to be shed, so a woman called 'The...

My Florida Alphabet is not just another alphabet. Join Big Al, the tugboat, as he chugs through Florida from A to Z. And sing along, performing the gestures for each letter. Research continues to prove that adding movement, music, and rhythm facilitates learning. The authors have used this method in their classrooms with fast and amazing results.

Includes a CD of My Florida Alphabet song.

This monograph contains an in-depth analysis of the dynamics given by a linear Hamiltonian system of general dimension with nonautonomous bounded and uniformly continuous coefficients, without other initial assumptions on time-recurrence.
