Business Value From Intelligent Fields [PDF]

open access: yesProceedings of SPE Intelligent Energy Conference and Exhibition, 2010
Abstract The Smart Fields programme has been active in Shell over the last decade and has given large benefits. In order to understand the value and to underpin strategies for the future implementation programme, a study was carried out to quantify the benefits to date.

Sharp rigidity estimates for incompatible fields as a consequence of the Bourgain Brezis div-curl result

open access: yesComptes Rendus. Mathématique, 2021
In this note we show that a sharp rigidity estimate and a sharp Korn’s inequality for matrix-valued fields whose incompatibility is a bounded measure can be obtained as a consequence of a Hodge decomposition with critical integrability due to Bourgain ...

HENSELIAN VALUED FIELDS AND inp-MINIMALITY [PDF]

open access: yesJournal of Symbolic Logic (JSL), 2016
We prove that every ultraproduct of p-adics is inp-minimal (i.e., of burden 1). More generally, we prove an Ax-Kochen type result on preservation of inp-minimality for Henselian valued fields of equicharacteristic 0 in the RV language.

Intuitionistic and Interval-Valued Fuzzy Set Representations for Data Mining

open access: yesAlgorithms, 2022
Data mining refers to a variety of techniques in the fields of databases, machine learning and pattern recognition. The intent is to obtain useful patterns and associations from a large collection of data.

On the structure of certain valued fields [PDF]

open access: yesAnnals of Pure and Applied Logic, 2016
For any two complete discrete valued fields $K_1$ and $K_2$ of mixed characteristic with perfect residue fields, we show that if each pair of $n$-th residue rings is isomorphic for each $n\ge1$, then $K_1$ and $K_2$ are isometric and isomorphic.

Semisimple groups interpretable in various valued fields

open access: yesForum of Mathematics, Sigma
We study infinite groups interpretable in power bounded T-convex, V-minimal or p-adically closed fields. We show that if G is an interpretable definably semisimple group (i.e., has no definable infinite normal abelian subgroups) then, up to a finite ...

On the local univalence of nondegenerate holomorphic vector fields

open access: yesComptes Rendus. Mathématique, 2020
We prove that, in all dimensions, germs of nondegenerate holomorphic vector fields on complex manifolds are univalent in the sense of Palais (semicomplete in the sense of Rebelo), this is, that there exist neighborhoods of their singular points where all

Fixed/Preassigned-Time Stochastic Synchronization of Complex-Valued Fuzzy Neural Networks with Time Delay

open access: yesMathematics, 2023
Instead of the separation approach, this paper mainly centers on studying the fixed/preassigned-time (FXT/PAT) synchronization of a type of complex-valued stochastic fuzzy cellular neural networks (CVSFCNNs) with time delay based on the direct method ...

Brauer $p$-dimension of complete discretely valued fields [PDF]

open access: yesTransactions of the American Mathematical Society, 2016
Let K be a complete discretely valued field of characteristic 0 with residue field k of characteristic p. Let n=[k:k^p] be the p-rank of k. It was proved by Parimala and Suresh that the Brauer p-dimension of K lies between n/2 and 2n.
