Observability of Uncertain Nonlinear Systems Using Interval Analysis

open access: yesAlgorithms, 2020
In the field of control engineering, observability of uncertain nonlinear systems is often neglected and not examined. This is due to the complex analytical calculations required for the verification.

Path integral representation for inverse third order wave operator within the Duffin-Kemmer-Petiau formalism. Part I

open access: yesJournal of High Energy Physics, 2020
Within the framework of the Duffin-Kemmer-Petiau (DKP) formalism with a deformation, an approach to the construction of the path integral representation in parasuperspace for the Green’s function of a spin-1 massive particle in external Maxwell’s field ...

Analysis of Interturn Faults on Transformer Based on Electromagnetic-Mechanical Coupling

open access: yesEnergies, 2023
A running transformer frequently experiences interturn faults; they are typically difficult to detect in their early stages but eventually progress to interturn short circuits, which cause damage to the transformer.

Transformer Fault Early Warning Analysis Based on Hierarchical Clustering Combined with Decision Trees

open access: yesEnergies, 2023
The issues of low accuracy, poor generality, high cost of transformer fault early warning, and the subjective nature of empirical judgments made by field maintenance personnel are difficult to solve with the traditional measurement methods used during ...

Control theory for principled heap sizing [PDF]

open access: yes, 2013
We propose a new, principled approach to adaptive heap sizing based on control theory. We review current state-of-the-art heap sizing mechanisms, as deployed in Jikes RVM and HotSpot.

Controlled K-theory

open access: yesTopology and its Applications, 1995
As an editor, the senior author of this paper is well known for his very commendable effort to make authors write informative introductions to their papers. It is a pleasure to report that this paper lives up to such a demand, and thus to be able to quote briefly from the introduction without feeling that as a reviewer one ought do better: ``In this ...

Dynamic changes of key enzymes activity in a bromate and perchlorate-reducing hydrogen-based membrane biofilm reactor [PDF]

open access: yesE3S Web of Conferences, 2020
In this study, the microorganisms in different stages of MBfR were cultured, by using kits to detect the dynamic changes of key enzymes activity, and exploring the effects of biofilm microorganisms on key enzymes activity of MBfR.
