Introduction à la modélisation de l'écriture manuscrite par des courbes Bézier Rationnelles massiques

2019

National audience; L’article est une introduction à la modélisation de l’écriture manuscrite. La représentation de l’écriture cursive in- terfère, selon l’approche hors ligne ou en ligne, sur la robustesse des algorithmes de reconnaissance des caractères manuscrits, de l’identification des auteurs et de leur signature. Les caractéristiques de base de l’écriture cursive que sont les traits et leur inclinaisons, les boucles, les pleins et déliés peuvent être modélisés par des courbes. Des méthodes existent. Elles reposent sur les B-splines et leur points de contrôle. Dans un premier temps, des traits, les auteurs proposent une modélisation, rebroussements, boucles, arrondis, pleins et déliés.…

Abemaciclib: safety and effectiveness of a unique cyclin-dependent kinase inhibitor

2020

Introduction: The discovery and the clinical availability of novel cyclin-dependent kinases 4 and 6 inhibitors have profoundly changed the therapeutic scenario of metastatic hormone receptor-positive breast carcinoma. Among these inhibitors, abemaciclib can induce potent and sustained cell cycle arrest and immune system stimulation. Areas covered: This review summarizes the safety profile and clinical efficacy data on abemaciclib alone or in combination with aromatase inhibitors or fulvestrant in metastatic hormone receptor-positive breast carcinoma. The management of patients treated with abemaciclib is the object of this paper. Expert opinion: As shown in phase 2 and 3 clinical trials on …

Jacobi Fields, Conjugate Points

2001

Let us go back to the action principle as realized by Jacobi, i.e., time is eliminated, so we are dealing with the space trajectory of a particle. In particular, we want to investigate the conditions under which a path is a minimum of the action and those under which it is merely an extremum. For illustrative purposes we consider a particle in two-dimensional real space.

Social Collaborative Viewpoint Regression with Explainable Recommendations

2017

A recommendation is called explainable if it not only predicts a numerical rating for an item, but also generates explanations for users' preferences. Most existing methods for explainable recommendation apply topic models to analyze user reviews to provide descriptions along with the recommendations they produce. So far, such methods have neglected user opinions and influences from social relations as a source of information for recommendations, even though these are known to improve the rating prediction. In this paper, we propose a latent variable model, called social collaborative viewpoint regression (sCVR), for predicting item ratings based on user opinions and social relations. To th…

Modelling Recurrent Events for Improving Online Change Detection

2016

The task of online change point detection in sensor data streams is often complicated due to presence of noise that can be mistaken for real changes and therefore affecting performance of change detectors. Most of the existing change detection methods assume that changes are independent from each other and occur at random in time. In this paper we study how performance of detectors can be improved in case of recurrent changes. We analytically demonstrate under which conditions and for how long recurrence information is useful for improving the detection accuracy. We propose a simple computationally efficient message passing procedure for calculating a predictive probability distribution of …

POSITIONING ROMANIA AS A TOURISM DESTINATION BASED ON THE INFORMATION FROM ONLINE TRAVEL GUIDES

2014

Concerned with asserting itself as a unique tourism destination, Romania has spent time and money and has put a lot of hope in choosing its brand elements and secondary associations, forgetting that brands are not built only through advertising. The points of contact through which customers get to know a brand are various: observation and personal use, oral advocacy, interactions with Romania’s citizens, online and mobile experiences, etc. This paper aims to highlight the importance of Romania’s positioning statement, as a tourism destination, based on the information from major online international travel guides, and to argue the harmonization of this approach in differentiating the brand …

Courbes de Bézier quadratiques et nombres complexes massiques

2017

International audience; Les courbes de Bézier quadratiques jouent un rôle fondamental pour la modélisation d'arcs de coniques. L'utili-sation de points massiques permet de modéliser des demi-coniques dans le plan affine euclidien ou des surfaces canal dans l'espace de Minkowski-Lorentz. L'utilisation des nombres complexes permet de simplifier beaucoup de raisonnements en géométrie et de simplifier l'utilisation des transformations affines planes. Dans cet article, nous définissons dans un premier temps les nombres complexes massiques et dans un second temps, nous modéli-sons des arcs de coniques en utilisant des courbes de Bézier rationnelles quadratiques avec des points complexes massiques…

Stories of professional development in physiotherapy education

2022

This study examines graduating physiotherapy students’ narratives related to their professional development. The data comprised interviews with 33 graduating physiotherapy students. The data were analyzed using the narrative analysis approach. As a result, five different story models were identified. The descriptive story models were named: 1) “Study path dominated by life changes”; 2) “Realizing the connection between physiotherapy theory and practice”; 3) “Self-regulated and practical-oriented learning path”; 4) “Becoming a critical developer”; and 5) “Multiprofessional working towards expertise”. In students’ stories, there appeared different turning points that illustrated especially me…
