El presente artículo parte de un caso de estudio concreto que es la investigación en torno al archivo del colectivo artístico “Fundación Rodríguez” (Vitoria-Gasteiz, 1994-2012). El proceso de investigación estará marcado por todo lo que conlleva enfrentarse a un archivo compuesto por contenido digital y con formatos a punto de la obsolescencia, así como las dificultades para su conservación y mantenimiento. Partiendo de esto, se contextualizará la práctica de “Fundación Rodríguez” y el papel que juega el concepto de archivo en varias de las fases de su producción artística. Para ello analizaremos su posición desde el trabajo colectivo, la disolución del rol del artista y la desmaterialización de la obra artística como los tres frentes principales desde los que se erige su producción. Con todo, podremos valorar desde la actualidad la vigencia y relevancia de su legado, así como la potencia del mismo en el contexto artístico al que pertenece. This article starts from a concrete case study that is the research around the archive of the artistic collective “Fundación Rodríguez” (Vitoria-Gasteiz, 1994-2012). The research process will be marked by all that is involved in dealing with an archive composed of digital content and formats on the verge of obsolescence, as well as the difficulties of preserving and maintaining them. Starting from this, the practice of “Fundación Rodríguez” and the role played by the concept of archive in several of the phases of its artistic production will be contextualized. To do so, we will analyze its position from the perspective of collective work, the dissolution of the role of the artist and the dematerialization of the artistic work as the three main fronts from which its production is built.With all this, we will be able to evaluate from the present time the validity and relevance of his legacy as well as its power in the artistic context to which it belongs.

Abstract The numerous applications of internet of things (IoT) and sensor networks combined with specialized devices used in each has led to a proliferation of domain specific middleware, which in turn creates interoperability issues between the corresponding architectures and the technologies used. But what if we wanted to use a machine learning algorithm to an IoT application so that it adapts intelligently to changes of the environment, or enable a software agent to enrich with artificial intelligence (AI) a smart home consisting of multiple and possibly incompatible technologies? In this work we answer these questions by studying a framework that explores how to simplify the incorporation of AI capabilities to existing sensor-actuator networks or IoT infrastructures making the services offered in such settings smarter. Towards this goal we present eVATAR+, a middleware that implements the interactions within the context of such integrations systematically and transparently from the developers’ perspective. It also provides a simple and easy to use interface for developers to use. eVATAR+ uses JAVA server technologies enhanced by mediator functionality providing interoperability, maintainability and heterogeneity support. We exemplify eVATAR+ with a concrete case study and we evaluate the relative merits of our approach by comparing our work with the current state of the art.

Ready Mix Concrete

Ready-mix concrete (RMC) in Tunisia is becoming more and more in demand in the civil engineering sector thanks to its qualities of handling in the fresh state and resistance in the hardened state, this composite material must respect the quality-price ratio. A RMC with a minimal cost is the object of our work. This research is part of the opening of higher education on professional life, where we optimized the formulation of a RMC. This work has 3 axes. In the first place the resources in building materials were characterized, namely various samples of sand, gravel, cement and water. Subsequently, the adjuvant-cement ratio (A/C) was optimized. Finally, the workability of the concrete as well as its mechanical aptitude at various ages 7, 14 and 28 days were characterized. These examinations have resulted in an appropriate formulation for any type of resource that varies according to the provenance of the quarries (gravel and sand), the effect of the plasticizer-water reducer is found for a very interesting A/C ratio, the mechanical tests for different ages are also conclusive.

Further Development

Abstract As researchers from different nationalities and disciplines collaborate in research projects with joint grants, science becomes more and more global. For conducting the research, project members from several different professional and national backgrounds work together on a daily basis using English as lingua franca (ELF). This results in a very heterogenic linguistic setting, influenced by several mother tongues and languages for specific purposes (LSPs). Systematic approaches have been neglected during the last years while LSP research moved more and more towards applied approaches working on concrete case studies. The present study follows an alternative approach. Applied linguistics and further development of systematic approaches shall here be seen as a circular flow. For instance, communication optimisation during a case study benefits from system-thinking and vice versa. How could the project language of a case study be structured and which long established classifications need to be revised based on these data? Is there a need for a new understanding of applied LSP research?

Criterion Of Identity

Abstract This is Part A of an article that defends non-eliminative structuralism about mathematics by means of a concrete case study: a theory of unlabeled graphs. Part A summarizes the general attractions of non-eliminative structuralism. Afterwards, it motivates an understanding of unlabeled graphs as structures sui generis and develops a corresponding axiomatic theory of unlabeled graphs. As the theory demonstrates, graph theory can be developed consistently without eliminating unlabeled graphs in favour of sets; and the usual structuralist criterion of identity can be applied successfully in graph-theoretic proofs. Part B will turn to the philosophical interpretation and assessment of the theory.
