Resolving requirements discovery in testing and operations

Journal of Lightwave Technology, 2004
We describe the results of an investigation into requirements discovery during testing and operations. Requirements discovery includes both new requirements and new knowledge regarding existing requirements. Analysis of anomaly reports shows that many of the anomalies that occur during these phases involve requirements discovery.

ON THE RESOLVENT OPERATOR OF DYNAMIC DIRAC OPERATORS

2023
In this article, we investigate the resolvent of dynamic Dirac operators on unbounded time scales. For the resolvent of these operators, integral representations are obtained. Finally, a formula for the Titchmarsh–Weyl function is given.

OPERATOR-VALUED PSEUDODIFFERENTIAL OPERATORS AND THE RESOLVENT OF A DEGENERATE ELLIPTIC OPERATOR

Mathematics of the USSR-Sbornik, 1984
Let Y be a smooth manifold with boundary X. Let A be an elliptic differential operator of order \(2\ell\) degenerated on X. The author constructs the parametrix for the Dirichlet problem using operator-valued pseudo-differential operators.

Regularized Resolvent of Sums of Commuting Operators

Acta Mathematica Hungarica, 2001
For \(B_1\) and \(B_2\) two commuting linear (not necessarily bounded) operators on a Banach space, the question of when \((B_1-B_2)\) has a bounded inverse on \(X\) is of interest. For example, consider the abstract Cauchy problem \[ {{d}\over{dt}}u(t)= A(u(t))+ f(t) \qquad (0\leq t\leq T), \] where \(A\) is a linear operator on a Banach space \(W\), \

Strong Resolvent Convergence of Diffusion Operators

SIAM Journal on Mathematical Analysis, 1985
It is shown that differential operators arising from boundary value problems with eigenvalue parameter in the boundary condition occur as the limits, in the sense of a generalized notion of strong resolvent convergence, of families of Sturm–Liouville operators modeling heat flow in a rod, where the diffusion coefficient becomes arbitrarily large in ...
