Model transformations and Tool Integration

Model transformations are increasingly recognised as being of significant importance to many areas of software development and integration. Recent attention on model transformations has particularly focused on the OMGs Queries/Views/Transformations (QVT) Request for Proposals (RFP). In this paper I motivate the need for dedicated approaches to model transformations, particularly for the data involved in tool integration, outline the challenges involved, and then present a number of technologies and techniques which allow the construction of flexible, powerful and practical model transformations

Une micro-politique de la peinture. Entretien avec Varr, La Plata, Argentine

Entrevista realizada el 13/08/2021, en La PlataInternational audienceVARR, Valentina Andrea Rivas Robles, was born in Concepción, Chile, in 1989. Artist, painter, activist, VARR currently lives in the city of La Plata. In this dialogue, various aspects of her artistic practice are analysed. Her artistic practice takes place mainly in the street, a space she considers a place of debate, of resistance, but also a place of creation. Walking in the city, the "cirujeo" of materials, the creation of installations are some of the actions that he carries out on a daily basis, thus drawing a "micropolitics of painting".VARR, Valentina Andrea Rivas Robles, nació en Concepción, Chile, en 1989.

Artiste peintre, activiste, VARR vit à la ville de La Plata (Argentine) depuis quelques années. Dans cet entretien, divers aspects de sa pratique artistique, qui se déroule pour l’essentiel dans la rue – un espace de débat et de résistance, mais également de création – sont évoqués. La déambulation dans la rue, la « récup » de matériaux, la création d’installations font partie des actions qu’elle mène à bien au quotidien, esquissant ainsi une « micro politique de la peinture »

Transformation distances: a family of dissimilarity measures based on movements of segments.

Abstract MOTIVATION: Evolution acts in several ways on DNA: either by mutating a base, or by inserting, deleting or copying a segment of the sequence (Ruddle, 1997; Russell, 1994; Li and Grauer, 1991). Classical alignment methods deal with point mutations (Waterman, 1995), genome-level mutations are studied using genome rearrangement distances (Bafna and Pevzner, 1993, 1995; Kececioglu and Sankoff, 1994; Kececioglu and Ravi, 1995). The latter distances generally operate, not on the sequences, but on an ordered list of genes. To our knowledge, no measure of distance attempts to compare sequences using a general set of segment-based operations. RESULTS: Here we define a new family of distances, called transformation distances, which quantify the dissimilarity between two sequences in terms of segment-based events. We focus on the case where segment-copy, -reverse-copy and -insertion are allowed in our set of operations. Those events are weighted by their description length, but other sets of weights are possible when biological information is available. The transformation distance from sequence S to sequence T is then the Minimum Description Length among all possible scripts that build T knowing S with segment-based operations. The underlying idea is related to Kolmogorov complexity theory. We present an algorithm which, given two sequences S and T, computes exactly and efficiently the transformation distance from S to T. Unlike alignment methods, the method we propose does not necessarily respect the order of the residues within the compared sequences and is therefore able to account for duplications and translocations that cannot be properly described by sequence alignment. A biological application on Tnt1 tobacco retrotransposon is presented. AVAILABILITY: The algorithm and the graphical interface can be downloaded at http://www.lifl.fr/ approximately varre/TD</jats:p
