This paper is concerned with the problem of designing discrete-time control systems with closed-loop eigenvalues in a prescribed region of stability. First, we obtain a state feedback matrix which assigns all the eigenvalues to zero, and then by elementary similarity operations we find a state feedback which assigns the eigenvalues inside a circle with center   and radius. This new algorithm ca...

In this paper, a modified FCM (Fuzzy C-Means) algorithm based on Rough Set for image segment is proposed. The processes of the approach include two stages. In first stage, a cluster center set is built by reduction theory (the core of Rough Sets). In this stage, a decision table is designed firstly, where an initial cluster center set which contains granules with ill-defined boundaries is treat...

analysis of time series data can involve the inversion of large covariance matrices. for theclass of arma (p, q) processes there are no exact explicit expressions for these inverses, except for thema (1) process. in practice, the sample covariance matrix can be very large and inversion can becomputationally time consuming and so approximate explicit expressions for the inverse are desirable.thi...

We have prepared 3T3 cells doubly labeled to visualize simultaneously the extracellular fibronectin (FN) matrix and intracellular actin cytoskeleton in living cell cultures. We used FN-yellow fluorescent protein (FN-yfp) for the FN matrix, and the actin-binding domain of moesin fused to cyan fluorescent protein (cfp-Moe) to stain actin. Actin filament bundles were clearly seen in the protruding...

for all i, j . Thus in the (two-person, zero-sum) game with matrix Λf, player I has a strategy insuring an expected gain of at least v, and player II has a strategy insuring an expected loss of at most v. An alternative statement, which follows from the von Neumann theorem and an appropriate law of large numbers is that, for any ε>0, I can, in a long series of plays of the game with matrix M, g...

We study the asymptotic behavior of the averaged diagonal matrix elements of the Greens kernel for the Anderson Model on a one-dimensional strip and for a set of special energies close to the center of the band.
