Integrating time signals in frequency domain – Comparison with time domain integration
Measurement, 2014Abstract Integrating sampled time signals is a common task in signal processing. In this paper we investigate the performance of two straightforward integration methods: (i) integration in the frequency domain by a discrete Fourier transform (DFT), division by j ω followed by inverse DFT (IDFT) back to the time domain, and (ii) a method ...

In this chapter we focus on the theoretical underpinning and enabling technologies which ensure that the knowledge about the domain embedded in the software system remains current and is understood by the members of the VE.

Length Functions on Integral Domains
Proceedings of the American Mathematical Society, 1991Let R R be an integral domain and x ∈ R x \in R which is a product of irreducible elements. Let l ( x ) l(x) and L ( x ) L(x) denote respectively the inf and sup of the lengths of factorizations of

Factoring Ideals in Integral Domains
2013A classical generalization of the Fundamental Theorem of Arithmetic states that an integral domain is a principal ideal domain if and only if each of its proper ideals can be factored as a finite product of principal prime ideals. If the “principal” restriction is removed, one has a characterization of (nontrivial) Dedekind domains. The purpose of this

Domains, integration and ‘positive analysis’
Mathematical Structures in Computer Science, 2004This article surveys a variety of approaches to integration theory that have arisen in the context of continuous domain theory. The presentation is set in a broader context of ‘positive’ analysis, analysis where order-theoretic notions and notions of positivity play a key role.
