Story2Board: A Training‐Free Approach for Expressive Visual Storytelling
Computer Graphics Forum, EarlyView.Abstract We present Story2Board, a training‐free framework for expressive storyboard generation from natural language. Existing methods narrowly focus on subject identity, overlooking key aspects of visual storytelling such as spatial composition, background evolution, and narrative pacing.

Track wear-and-tear cost by traffic class: Functional form, zero output levels and marginal cost pricing recovery on the French rail network [PDF]
We address the issue of the allocation of railway track maintenance (wear-and-tear) costs to traffic output classes and consider a very general function relating maintenance cost C to a set of technical production characteristics K used to produce ...

Wear modelling of a rail-wheel system
, 2020 As one of the most efficient and aggregate means of transportation, the service life of the railway has been expected to be maintained or improved. The most important phenomenon within a rail-wheel system is the contact of rail and wheel ...

Prediction of top-of-rail friction control effects on rail RCF suppressed by wear
, 2017 Rolling contact fatigue (RCF) and wear, two major deterioration processes, limit the lifetime of rails. These deterioration processes are even more severe on the curves of tracks used by heavy haul trains.

Developmental Medicine &Child Neurology, EarlyView.Perspectives of parents of children with Dravet syndrome indicate that extreme heat and high temperatures exacerbate epileptic seizures, introduce new seizure triggers, and require the adoption of specific seizure‑management strategies. Abstract Aim To describe parental perspectives on how heatwaves and high ambient temperatures influence seizure ...

Disc machine testing to assess the life of surface-damaged railway track
, 2001 Wheel-rail contacts operate in an arduous and contaminated environment. Railway track running surfaces can become damaged either prior to or during operation.

core
, 2019 Railway crossings are subjected to a severe load environment leading to damage and degradation of rail profiles. The damage is the result of the high magnitudes of contact pressure and slip generated in the wheel–rail contacts during each wheel ...

Tribological and Physiochemical Properties of Greases for Rail Lubrication
Tribology Online, 2019 Rail lubrication is vital in determines the friction, wear and noise level in the wheel and rail contacts. In general, the primary function of a rail curve grease is to minimize friction between the contact as well as to protect side wear of rails on a ...

Mapping rail wear transitions [PDF]
, 2003 This paper outlines work carried out to produce maps of\ud rail material wear coefficients taken from laboratory\ud tests run on twin disc and pin-on-disc machines as well\ud as those derived from measurements taken in the field.\ud Wear transitions are identified using the maps and\ud defined in terms of slip and contact pressure.
