Phase-Field Reaction-Pathway Kinetics of Martensitic Transformations in a Model Fe3Ni Alloy

A three-dimensional phase-field approach to martensitic transformations that uses reaction pathways in place of a Landau potential is introduced and applied to a model of Fe3Ni. Pathway branching involves an unbounded set of variants through duplication and rotations by the rotation point groups of the austenite and martensite phases. Path properties, including potential energy and elastic tensors, are calibrated by molecular statics. Acoustic waves are dealt with via a splitting technique between elastic and dissipative behaviors in a large-deformation framework. The sole free parameter of the model is the damping coefficient associated to transformations, tuned by comparisons with molecular dynamics simulations. Good quantitative agreement is then obtained between both methods.Comment: 4 pages, 3 figure

Service Recovery for Severe Crises in The Cruise Industry

This experimental study examined what are the effects of expertise, blame, and service recovery on both purchase intentions and brand image after severe service failures. A 2x2x2 experimental design was conducted to measure the participants’ attitude toward communicators’ expertise, blame attribution, and distributive justice. This experiment was set within the cruise industry and was conducted on-line via Qualtrics. Participants were randomly assigned into eight treatment conditions. Written scenarios messages were employed to convey the different treatment conditions. In these scenarios, a fictitious spokesperson recalled an accident that had occurred while vacationing on a cruise ship. The level of expertise varied based on the past-experience of the spokesperson. This spokesperson was as either a first time or a long time cruiser. In terms of blame attribution, the accident was attributed either to a staff member or to a passenger. For the condition of service recovery, the cruise line offered a 20% discount on a future cruise and fully reimbursed the passengers or only a 20% discount. The main effect for recovery was significant (p<.05) for both brand image and intentions. There was also a significant interaction between expertise and blame attribution (p<.05) in terms of both intentions and brand image. Results offer both theoretical and practical insights in terms of advertising strategies and crisis management for cruise lines

Ondelettes monogènes couleur pour l'analyse d'image

4 pagesNational audienceNous proposons une transformée en ondelettes monogène couleur, basée sur une récente transformée monogène et une extension non marginale pour la couleur. Les schémas de traitement d'image couleur utilisant les ondelettes correspondent souvent à l'application d'un outil " niveaux de gris " sur chaque canal couleur séparément. Cela peut entraîner des effets indésirables sur la couleur lorsque ces schémas marginaux ne sont pas justifiés. Dans ce papier nous proposons une définition qui prends en compte une image couleur (vectorielle) dès le début de la construction mathématique, pour amener à une " vraie " transformée couleur. On obtient une analyse géométrique couleur multirésolution prometteuse pour l'image couleur
