Inflationary field excursion in broad classes of scalar field models
, 2016 In single field slow roll inflation models the height and slope of the potential are to satisfy certain conditions, to match with observations. This in turn translates into bounds on the number of e-foldings and the excursion of the scalar field during ...

Analysis of roll gap heat transfers in hot steel strip rolling through roll temperature sensors and heat transfer models [PDF]
, 2012 International audienceThis paper presents an analysis of roll bite heat transfers during pilot hot steel strip rolling. Two types of temperature sensors (drilled and slot sensors) implemented near roll surface are used with heat transfer models to ...

Optimization design of a novel X-type six-high rolling mill based on maximum roll system stiffness.
PLoS ONE, 2020 The present investigation devices a novel X-type six-high (X-6h) mill. In addition, parametric models of different roll layouts such as the four-high (4-h), I-type six-high (I-6h), and X-6h mills are established. Three-dimensional (3D) finite element (FE)

Observational constraints on an inflation model with a running mass [PDF]
, 1998 We explore a model of inflation where the inflaton mass-squared is generated at a high scale by gravity-mediated soft supersymmetry breaking, and runs at lower scales to the small value required for slow-roll inflation.

Advances in Mechanical Engineering, 2018 The work hardening of a spline during cold roll-beating is used as an indicator to evaluate the mechanical properties of the surface. To further optimize the work-hardening degree of a cold roll-beating spline surface, weight theory and satisfaction ...

Attractor behaviour in ELKO cosmology
, 2012 We study the dynamics of ELKO in the context of accelerated phase of our universe. To avoid the fine tuning problem associated with the initial conditions, it is required that the dynamical equations lead to an early-time attractor. In the earlier works,

Effects of local overloads on cold rolling mill work rolls [PDF]
International Journal of Mechanical Sciences, 2017 Abstract Local overloading is one of the most common reasons for premature failures of cold rolling mill work rolls. Case-hardened rolls demonstrate spatial variation of the material hardness and yield strength with a decreasing profile with depth and belong to the class of so-called plastically graded materials.

In-line metrology of functional surfaces with a focus on defect assessment on large area Roll to Roll substrates [PDF]
, 2013 This paper reports on the recent work carried out as part of the initial stages of the EU funded NanoMend project. The project seeks to develop integrated process inspection, cleaning, repair for nano-scale thin films on large area substrates.
