Equivariant $K$-theory of GKM bundles [PDF]

open access: yes, 2012
Given a fiber bundle of GKM spaces, $\pi\colon M\to B$, we analyze the structure of the equivariant $K$-ring of $M$ as a module over the equivariant $K$-ring of $B$ by translating the fiber bundle, $\pi$, into a fiber bundle of GKM graphs and ...

Greenberg algebras and ramified Witt vectors [PDF]

open access: yes, 2020
Let O be a complete discrete valuation ring of mixed characteristic and with finite residue field k. We study a natural morphism between the Greenberg algebra of O and the special fiber of the scheme of ramified Witt vectors over O.

Assessment of the Measurement and Prediction Methods for the Acoustic Properties of Natural Fiber Samples and Evaluation of Their Properties

open access: yesJournal of Natural Fibers, 2022
Although some studies have been conducted to show how natural fibers can replace synthetic materials, the use of many natural fibers is still limited.

Linewidth and frequency jitter measurement of an erbium-doped fiber ring laser by using a loss-compensated, delayed self-heterodyne interferometer [PDF]

open access: yes, 1992
The single-mode line width of erbium-doped, single-frequency, fiber ring laser has been measured by using a newly developed loss-compensated delayed self-heterodyne interferometer that has a resolution of less than 600 Hz.

Thermographic non-destructive evaluation for natural fiber-reinforced composite laminates [PDF]

open access: yes, 2018
Natural fibers, including mineral and plant fibers, are increasingly used for polymer composite materials due to their low environmental impact. In this paper, thermographic non-destructive inspection techniques were used to evaluate and characterize ...

Physical, thermal, mechanical, sound absorption and vibration damping characteristics of natural fiber reinforced composites and hybrid fiber reinforced composites: A review

open access: yesCogent Engineering, 2022
Adaptation of alternative and novel materials in place of traditional metals and alloys is getting higher attention in all domains of life. Tailored or customized fiber reinforced composite materials offer multiple advantages such as lighter systems with

Comparison between the fundamental group scheme of a relative scheme and that of its generic fiber [PDF]

open access: yes, 2010
We show that the natural morphism $\phi:\pi_1(X_{\eta},x_{\eta})\to \pi_1(X,x)_{\eta}$ between the fundamental group scheme of the generic fiber $X_{\eta}$ of a scheme $X$ over a connected Dedekind scheme and the generic fiber of the fundamental group ...

Green-reinforced Sedimentary Silt with Natural Curaua Fiber

open access: yesJournal of Natural Fibers, 2022
Lime and cement as traditional binders need to be reduced in soil stabilization to avoid carbon dioxide emissions. Infrastructure development like paved structures, buildings, foundations, and dams involves exhaustive use of natural resources and serious
