Anti-interrupted Sampling Repeater Jamming Method in the Waveform Domain before Matched Filtering
Leida xuebaoInterrupted Sampling Repeater Jamming (ISRJ) falls within the category of intrapulse coherent deception interference. ISRJ employs the principle of undersampling to engender multiple spurious target peaks on the range profile, thereby disrupting the ...

Journal of Algebra, 1984 This article introduces the concept of a conducive domain, that is, an integral domain each of whose overrings, apart from the quotient field, has nonzero conductor. The principal examples of conductive domains are all D\(+M\) constructions and all (pseudo-)valuation domains.

The Gaussian free field and Hadamard's variational formula [PDF]
, 2012 We relate the Gaussian free field on a planar domain to the variational formula of Hadamard which explains the change of the Green function under a perturbation of the domain.

The Control Problem for a Heat Conduction Equation with Neumann Boundary Condition
Vestnik KRAUNC: Fiziko-Matematičeskie NaukiPreviously, boundary control problems for a heat conduction equation with Dirichlet boundary condition were studied in a bounded domain. In this paper, we consider the boundary control problem for the heat conduction equation with Neumann boundary ...

Integral Closures of Noetherian Integral Domains as Intersections [PDF]
Proceedings of the American Mathematical Society, 1995 Let \(A\) be a noetherian integral domain, \(\overline A\) its integral closure, and let \({\mathcal G}\) be the set of prime ideals \(P\) of \(A\) with height\((P) \leq 1\). The author provides three equivalent conditions for the equality \(\overline A = \bigcap \overline A_P\), \(P \in {\mathcal G}\). For instance, equality holds iff \(\bigcap A_P\),
