Investigation of thermomechanical behavior of a work roll and of roll life in hot strip rolling [PDF]

Metallurgical and Materials Transactions A, 1998
An integrated finite element-based model is presented for the prediction of the steady-state thermomechanical behavior of the roll-strip system and of roll life in hot strip rolling. The model is comprised of basic finite-element models, which are incorporated into an iterative-solution procedure to deal with the interdependence between the ...

Revisiting Cosmic No-Hair Theorem for Inflationary Settings

, 2012
In this work we revisit Wald's cosmic no-hair theorem in the context of accelerating Bianchi cosmologies for a generic cosmic fluid with non-vanishing anisotropic stress tensor and when the fluid energy momentum tensor is of the form of a cosmological ...

Prediction and Simulator Verification of Roll/Lateral Adverse Aeroservoelastic Rotorcraft–Pilot Couplings [PDF]

, 2015
The involuntary interaction of a pilot with an aircraft can be described as pilot-assisted oscillations. Such phenomena are usually only addressed late in the design process when they manifest themselves during ground/flight testing. Methods to be able

USE OF HIGH SPEED STEEL WORK ROLLS (HSS) ON APERAM STECKEL MILL [PDF]

Tecnologia em Metalurgia, Materiais e Mineração, 2013
This paper outlines the main actions taken to reinforce the decision to use HSS work rolls on the Aperam Steckel Mill. These are: work roll cooling improvements, systematically analyzing Eddy Current and Ultrasonic non destructive tests, mechanical ...

Performance Analysis of Work-Roll Wear Models on Hot Rolling

Key Engineering Materials, 2022
The purpose of this work is to evaluate the performance of several wear models, either with different mathematical formulation or different definition of the unknown wear coefficients, on the prediction of the work-roll wear amplitude in Hot Strip Mills (HSM).

The making of the Ragman Roll: the work of the notary [PDF]

, 2011
Between the middle of May and the end of August 1296, during the course of a royal progress through the kingdom of Scots, via an eastern coastal route, having militarily asserted his authority over the leading nobles of Scotland, Edward I received ...

Natural selection of inflationary vacuum required by infra-red regularity and gauge-invariance

, 2011
It has been an issue of debate whether the inflationary infrared(IR) divergences are physical or not. Our claim is that, at least, in single-field models, the answer is "No," and that the spurious IR divergence is originating from the careless treatment ...

Axionic D3-D7 Inflation [PDF]

, 2008
We study the motion of a D3 brane moving within a Type IIB string vacuum compactified to 4D on K3 x T_2/Z_2 in the presence of D7 and O7 planes. We work within the effective 4D supergravity describing how the mobile D3 interacts with the lightest bulk ...

Cosmological constraints from Gauss-Bonnet braneworld with large-field potentials

, 2004
We calculate the spectral index and tensor-to-scalar ratio for patch inflation defined by $H^2\approx \beta^2_q V^q$ and $\dot{\phi}\approx -V'/3H$, using the slow-roll expansion.

An original fuzzy control approach for active anti-roll bars to prevent rollover.

PLoS ONE, 2023
In this article, the author introduces a new fuzzy control solution to direct active anti-roll bars (hydraulic stabilizer bars) in order to enhance the vehicle's roll stabilization efficiency.
