In mathematics, differential algebraic equations (DAEs) are a general form of (systems of) differential equations for vector–valued functions x in one independent variable t,They are distinct from ordinary differential equation (ODE) in that a DAE is not completely solvable for the derivatives of...
Solvers that are capable of dealing with implicit DAE descriptions directly have been coined differential algebraic equation solvers or DAE solvers. They are the focus point of this chapter. DOI: 10.1007/0-387-30260-3_8 被引量: 15 年份: 2006 ...
Fasting is defined as no caloric intake for at least 8 h; (3) 2-h plasma glucose X200 mg dl À 1 (11.1 mmol l À 1) during an oral glucose tolerance test. The test should be performed as described by the World Health Organization, using a glucose load containing the equivalent ...
The Values of the Algebra Tiles The Constant X Anything red is a negative Now, Show me if you’re with me. Describing the Additive Inverse If you have a positive and a negative of the same values, they cancel, or zero each other out. EX: = Zeroes out = Not zero Show me if you ...

An algebraic Riccati equation (ARE) approach to the reduced-order H{sup}∞ controller design problem is proposed. It is shown that the order of H{sup}∞ controller can be reduced to r, where r is the rank of the stabilizing solution W{sub}∞ to an ARE in W developed in Petersen, An...

We review some recent results concerning the symmetric algebraic matrix Riccati equation and especially its hermitian solutions. The main idea is description of such solutions in terms of invariant subspaces of a certain matrix, which is self-adjoint in an indefinite scalar product. Some new results...
