The Lyapunov Second Stability Method consists of select ing a so-called Lyapunov Candidate Function, which satisfies certain conditions that permit us to utilize it in the stability analysis of a mathematical model synthesized from a process which we want to put under action of a given Control Law. In linear cases, it is always possible to find a candidate function of quadratic kind, , that satisfies the desired cond5itions. By applying the Lyapunov Second Stability Method to this function, it appears an algebraic, ordinary matrix equations system of the kind , where P and Q are positive-definite matrices. In this work, the solution of this algebraic system by solving a lineal system of unknowns and same number of equations is proposed. After some elementary manipulation of original equations, solution can be achieved with some traditional method, like Gauss Inverse Deletion or any of its variants. This paper presents some easy algorithms that allow us to re-accommodate the original matrix system into a conventional algebraic, ordinary, linear equations system. Ax=b. .

The life and whines of an online poker player Hey guys, So as part of my joining Cardrunners I’ve been advised to start a blog. To be honest, I’ve never had a blog before so I’m going to try to keep up the updates on this thing regularly, but I hope that I can produce interesting and thoughtful entries. I’m kind of busy today so I can’t provide a proper introduction just yet, but I just wanted to make a few comments about my joining Cardrunners. Many people must know that I used to produce videos for Deucescracked, and it seems like there are some suggestions that Cardrunners was unscrupulous in acquiring me, or that I sold out, or that my switching sites is indicative of anything about either site. Let me assure you that this is absolutely not the case. I joined Cardrunners because they could offer me opportunities that other sites simply could not. I have no regrets about my work with Deucescracked, and my relationship with all of the people who I worked with there are wholly intact. As much as I enjoyed working there, it is my prerogative to do what I feel is in the best interests of my poker career. I hold no animosity toward anyone in the Deucescracked family, and they respect my decision to leave. There were several sites that offered me a deal to work with them, but I decided that none of them could offer what Cardrunners could. That being said, I don’t want to sound like a zealot and I have enough self-awareness to know that I have to do some proving to show that I’m committed to working for  Cardrunners, so that’s exactly what I intend to do. Within the next couple days I’ll try to post a more comphehensive introduction and a brief story of my poker history, but for now I hope you guys are willing to welcome me into the Cardrunners family – and of course enjoy my videos. 🙂 . On hero calls     I’ve been kind of lazy lately, but I thought I might enter in another blog entry since I had a couple of hands fresh on my mind. I’ll get around to a lifestory sort of post a little bit later, but for now I wanted to write a bit about hero calls, since I’ve gotten a few questions about them lately. Hero calls...
