Research on Diaphragm Pump Fault Diagnosis Method Based on Res‐DCB‐Net

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Nonstationary pressure pulsation signals of diaphragm pumps contain strong background noise and coupled characteristics. This makes it challenging to extract incipient fault features and to decouple faults with similar physical mechanisms. To address these limitations, this paper proposes a spatiotemporal fault diagnosis model named Res‐DCB ...

Sharp conditions for the classical asymptotic behaviour near a point for solutions to quasilinear elliptic systems

open access: yes, 2004
It is well known that distributional solutions of an elliptic equation with constant coefficients behave asymptotically near an interior point as sums of polynomials and linear combinations of derivatives of a fundamental solution. We consider a class of

A New Paradigm for Understanding the Rheology and Processability of Poly(p‐Phenylene Terephthalamide) Liquid‐Crystalline Solutions

open access: yesJournal of Applied Polymer Science, EarlyView.
Kevlar is traditionally modeled as a rigid‐rod polymer, yet rheological behavior deviates from this assumption. The review introduces a novel “twist‐tie” entanglement theory for aramid polymer chains in the nematic liquid crystal state, providing a molecular explanation for deviations from rigid‐rod models. Understanding twist‐tie entanglement dynamics

On the relation between (C,E,P)–algebras and asymptotic algebras [PDF]

open access: yes
On several occasions, the question has been asked whether (C,E,P)–algebras as introduced by Marti (1999), go beyond the framework of asymptotic algebras as deï¬ned by Delcroix and Scarpalezos (1998).

Microwave‐Assisted Alcoholysis of Ethylene–Vinyl Acetate: Phenomenological and Thermal Evolution of EVAOH Terpolymers

open access: yesJournal of Applied Polymer Science, EarlyView.
Microwave‐assisted alcoholysis converts EVA into EVAOH terpolymers, promoting a progressive transition from EVA‐like crystallites to VOH‐rich hydrogen‐bonded crystalline domains. Solvent‐controlled swelling influences conversion kinetics, while thermal analysis reveals a sigmoidal increase in melting temperature that a two‐population crystallization ...

Asymptotic theory of integrated conditional moment tests

open access: yes
In this paper we derive the asymptotic distribution of the test statistic of a generalized version of the integrated conditional moment (ICM) test of Bierens (1982, 1984), under a class of Vn-local alternatives, where n is the sample size.

Long‐Range Interactions in Topological Superconducting Systems: A Mini Review

open access: yesAdvanced Physics Research, EarlyView.
Long‐range interacting quantum systems are surveyed in this review, with an emphasis on the long‐range topological superconductor and its variants. Long‐range interactions decaying in a power‐law manner can lead to exotic phenomena that finds no analogue in short‐range regimes.
