The Sobolev-type moment problem [PDF]

open access: yes, 2000
9 pages, no figures.-- MSC2000 codes: Primary 44A99; Secondary 47B15, 47B20, 47B25.MR#: MR1694873 (2000k:44006)Zbl#: Zbl 0951.44002We propose necessary and sufficient conditions for a bisequence of complex numbers to be a moment one of Sobolev type over ...

The Problem of Expanding Semantic Fields and Untranslatability at Word-Level

open access: yesArmenian Folia Anglistika, 2007
The article discusses the issue of untranslatability at the lexical level considering the expansion of the meanings of root words and other elements of word formation as a result of the development of the language.

Poszukiwanie niejednorodności plastycznej materiału dla całkowicie uplastycznionych cylindrów kołowych, poddanych działaniu obciążeń złożonych

open access: yesEngineering Transactions, 1990
W pracy poszukuje się takiego rozkładu granicy plastyczności materiału, który umożliwia całkowite uplastycznienie przy wyczerpaniu nośności granicznej kołowych cylindrów grubościennych poddanych działaniu obciążeń złożonych (ciśnienie, niewielki moment ...

On entropy-constrained Gaussian channel capacity via the moment problem

open access: yes
We study the capacity of the power-constrained additive Gaussian channel with an entropy constraint at the input. In particular, we characterize this capacity in the low signal-to-noise ratio regime, as a corollary of the following general result on a ...

Novel loop-diagrammatic approach to QCD θ parameter and application to the left-right model

open access: yesJournal of High Energy Physics, 2023
When the QCD axion is absent in full theory, the strong CP problem has to be explained by an additional mechanism, e.g., the left-right symmetry. Even though tree-level QCD θ ¯ $$ \overline{\theta} $$ parameter is restricted by the mechanism, radiative ...

Needle in a haystack: Coarse-to-fine alignment network for moment retrieval from large-scale video collections.

open access: yesPLoS ONE
Moment retrieval from large-scale video collections aims to search and localize the temporal boundary of a video moment from a collection of numerous videos according to the given natural language query.

Equilibrium and stability of beams with elastoplastic semi-rigid joints [PDF]

open access: yesArchives of Civil Engineering
The classical theory of beams admits two types of connections between structural elements: perfectly rigid and perfectly flexible. However, the engineering reality calls for a more general approach to joint modelling.

Temporal moments of a tracer pulse in a perfectly parallel flow system

open access: yes, 2002
Perfectly parallel groundwater transport models partition water flow into isolated one-dimensional stream tubes which maintain total spatial correlation of all properties in the direction of flow.

Robust and Adaptive Path-Following Control of an Underactuated Ship

open access: yesIEEE Access, 2020
The design of a vessel path-following control system based on a full, realistic, nonlinear model is considered. The control objective is to force a surface, course-unstable vessel to track a predefined geometric path.

MATHICSE Technical Report : Tensor train approximation of moment equations for the log-normal Darcy problem [PDF]

open access: yes
We study the Darcy problem with log-normal permeability, modeling the fluid flow in a heterogeneous porous medium. A perturbation approach is adopted, expanding the solution in Taylor series around the nominal value of the permeability.
