Pre-asymptotic Expansions

open access: yesJournal of Mathematical Analysis and Applications, 1996
Let \(\{V_n\}\) be a sequence of vector spaces with \(V_{n + 1} \subseteq V_n\) for \(n = 0,1,2, \dots\). A series \(\sum^\infty_{n = 0} v_n\) with \(v_n \in V_n\) is called a pre-asymptotic expansion of \(v \in V_0\), written \(v \sim \sum^\infty_{n = 0} v_n\) with respect to \(\{V_n\}\), if \(v - \sum^N_{n = 0} v_n \in V_{N + 1}\) for all \(N ...

Extremal properties of the beta-normal distribution

open access: yesJournal of Inequalities and Applications, 2022
Asymptotic behaviors of the extremes of the beta-normal distribution are derived. The higher-order asymptotic expansions of the probability density and cumulative distribution functions for the maximum are given under an optimal normalizing constants. In

Generalised Asymptotic Solutions for the Inflaton in the Oscillatory Phase of Reheating

open access: yesUniverse, 2021
We determine generalised asymptotic solutions for the inflaton field, the Hubble parameter, and the equation-of-state parameter valid during the oscillatory phase of reheating for potentials that close to their global minima behave as even monomial ...

Observer‐Based Adaptive Event‐Triggered Tracking Control for Fuzzy TS Systems With Premise Mismatch

open access: yesInternational Journal of Adaptive Control and Signal Processing, EarlyView.
This paper presents an adaptive logistic event‐triggered observer‐based tracking controller for Takagi‐Sugeno fuzzy systems under constrained inputs and network delays. Leveraging a hybrid LMI and Secretary Bird Optimization approach, this strategy significantly minimizes communication overhead and computational burden while ensuring optimal reference ...

Karl Popper and the Mechanisms of Hydrogen Embrittlement

open access: yesAdvanced Engineering Materials, EarlyView.
Representation of the beginning of loss of ductility rather than embrittlement. Small concentrations of hydrogen in a diffusible form within iron are well‐established to harm the mechanical integrity of steels. There are theories that attempt to explain the pernicious role of hydrogen.

Soft Mechanical‐Electrical Logic Using Liquid Metal‐Filled 3D‐Printed Architectures

open access: yesAdvanced Engineering Materials, EarlyView.
We present 3D‐printed soft mechanical–electrical logic elements that use liquid metal–filled silicone tubes actuated by thermoplastic polyurethane/polylactic acid (TPU/PLA) architectures to produce Boolean operations. Complementary normally open and normally closed unit cells perform repeatable binary transitions and can be combined into more complex ...

Molecular Dynamics Studies of Shape Memory Polymers: From Bead–Spring Models to Atomistic Simulations

open access: yesAdvanced Engineering Materials, EarlyView.
Coarse‐grained (left) and atomistic (right) models of the shape memory polymer ESTANE ETE 75DT3 are shown schematically. The two representations bridge molecular detail and mesoscopic description. Both models capture shape memory behavior, linking segmental mobility and conformational relaxation of anisotropic chains to macroscopic recovery, and ...

A class of generalized uniform asymptotic expansions

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1978
In [1] E. L. Reiss obtained a multivariable expansion of the problem L[y]≡y″+2ϵy′+y=0, t>0;y(0;ϵ)=0, y′(0,ϵ)=1 by means of a technique which does not employ the traditional method of using a secularity condition in obtaining higher order approximations ...
