This book shows how the use of S-variables (SVs) in enhancing the range of problems that can be addressed with the already-versatile linear matrix inequality (LMI) approach to control can, in many cases, be put on a more unified, methodical footing. Beginning with the fundamentals of the SV approach, the text shows how the basic idea can be used for each problem (and when it should not be employed at all). The specific adaptations of the method necessitated by each problem are also detailed. The problems dealt with in the book have the common traits that: analytic closed-form solutions are not available; and LMIs can be applied to produce numerical solutions with a certain amount of conservatism. Typical examples are robustness analysis of linear systems affected by parametric uncertainties and the synthesis of a linear controller satisfying multiple, often conflicting, design specifications. For problems in which LMI methods produce conservative results, the SV approach is shown to achieve greater accuracy.The authors emphasize the simplicity and easy comprehensibility of the SV approach and show how it can be implemented in programs without difficulty so that its power becomes readily apparent. The S-variable Approach to LMI-based Robust Control is a useful reference for academic control researchers, applied mathematicians and graduate students interested in LMI methods and convex optimization and will also be of considerable assistance to practising control engineers faced with problems of conservatism in their systems and controllers.

In a time of misfortune and loss, the kingdom of Bullan is ruled by a greedy and murderous king. He demands exorbitant taxes of his people and when his demands are not fulfilled, the consequences are severe. Death knocks on every door sooner or later, and unfortunately it was sooner for young Emersyn Hale. When the king's guards killed her twin brother and her father, Emersyn was forced to hide and listen while Death did his work. Now, nine years later, eighteen-year-old Emersyn is a different person, forged from a life of crime and a burning desire for revenge. Her people call her Robyn Hoode, but only her band of thieves knows her true identity. She is a hero who will do anything to steal from the king and give back to those who need it most. But putting an end to Hoode's crimes becomes the ruthless king's top priority. Now it seems the consequences of her long-term actions may be her own appointment with Death.
A short, concise and user-friendly guide to the essential procedures of conducting a meeting, written by the authors of Robert's Rules of Order Newly Revised, the only authorized edition of the classic work on parliamentary procedure.Originally published in 1876, General Henry M. Robert's guide to smooth, orderly, and fairly conducted meetings has sold over six million copies in eleven editions. Robert's Rules of Order is the book on parliamentary proceedings, yet those not well versed on what has now become a rather thick document can find themselves lost--and delayed--while trying to locate the most important rules. The solution? Robert's Rules of Order Newly Revised in Brief.Written by the same authorship team behind the officially sanctioned Robert's Rules of Order, this short and user-friendly edition takes readers through the rules most often needed at meetings--from debates to amendments to nominations. With sample dialogues and a guide to using the complete edition, Robert's Rules of Order Newly Revised in Brief is the essential handbook for parliamentary proceedings.
Hannah & Rob's Little Book of Viola Jokes takes a look at that most popular of jokes in classical music circles. There's a "brief history" of the Viola Joke from Shakespeare right up to Jake the Dog, and then jokes about violas, jokes about viola players, jokes that might require a little bit of musical knowledge, a few slightly more grown-up jokes about violas and some jokes which work as stories. Then, at the end, to balance things out, there are a few jokes about other musicians Robert Steadman is a composer and conductor while Hannah Borrill is a violinist, composer and..... viola player
