Applying advanced nonlinear capacity methods, one can extend this pioneering result to the case of the following quasilinear inequality: −∑𝑖,𝑗=1𝑛∂2∂𝑥𝑖∂𝑥𝑗𝑎𝑖,𝑗(𝑥,𝑢)≥𝑏(𝑥)|𝑢|𝑞, (1) where 𝑎𝑖,𝑗 are Caratheodory functions of 𝑛+...
Addition is an obvious example of this pattern. For example, the result ofadd 1thenadd 2is the same as the result ofadd 2followed byadd 1. This pattern, generalized, can produce a wide range of useful properties. We’ll see some more uses of this pattern later in this post. “There ...
We consider operator-valued positive-real functions H and show that the intersections of the point, continuous and residual spectra of H(s) with the imaginary axis do not depend on s. In particular, if H is positive real and H(z) is invertible for some z in the open right-half plane,...
Provides information on the development of methods of generating direct inverse kinematics functions for nonredundant manipulators. How input and output data can be analyzed for certain classes of revolute joint regional manipulators; Approximation of inverse kinematic mappings; Description of the topology ...
A random vector having a MV-N distribution with mean and covariance is just a linear function of a "standard" MV-N vector: Proposition Let be a random vector having a MV-N distribution with mean and covariance . Then,where is a standard MV-N vector and is a invertible matrix such that...
In this paper various properties of discrete-time dynamic control systems trajectories with respect to state-space corner regions are considered. The known notion of state-space invariance serves as a basis for derivation of the whole family of dynamics behaviors for which both necessary and sufficien...
The structural properties of several compositions of Ge-Sb-Te liquids are studied from a combination of neutron diffraction and density functional-based molecular dynamics. We investigate structural properties including structure factors, pair distribution functions, angular distributions, coordination numbers,...
A singular matrix is a square matrix whose determinant is zero and is considered noninvertible. A noninvertible matrix is a matrix that does not have an inverse. An inverse is the reciprocal of a number; the reciprocal of a number means to flip a number over. Oppositely, there are non-si...
