Use of corrugated steels in construction applications

The Research Group of Materials Performance works in the study of several corrugated steels, especially stainless steels. Different aspects are developed as corrosion tests and evaluation of welded joints, between similar and dissimilar materials. It is sought to find construction companies interested in the application of this technology.Contrato Programa de Comercialización e Internacionalización.

Dora maar & margaret michaelis: two photographers in front of the art and architecture

El interés por la labor callada del artista en su estudio o la atención continuada a la lenta gestación de la arquitectura, han sido constantes desde hace tiempo. Los buenos fotógrafos han estado siempre dispuestos a poner su mirada atenta sobre estos procesos. Resulta sumamente interesante desgranar lo ocurrido en este campo en las primeras décadas del siglo xx, y muy especialmente en los años que precedieron a la guerra civil española. De aquellos años, me fijaré en las figuras de dos mujeres fotógrafas –Dora Maar y Margaret Michaelis–, que entendieron el seguimiento de los procesos creativos como parte fundamental de su creación artistica y, gracias a las cuales, descubriremos a sus autores, visualizaremos los escenarios de su gestación y disfrutaremos con la plástica de sus procesos constructivos.The interest of the silent work of the artist in his studio or the continued attention of the slow gestation of the architecture, have been constant since long time ago. The good photographers have always been ready to put their careful look on this processes. It’s very interesting to peel what ocurred in the first decades of the 20Th century, and specially on the years before the spanish civil war. In this years, I will observe the figures of two women photographers – Dora Maar and Margaret Michaelis– that understood the creative processes as a fundamental part of the artistic creation, and thanks to which, we discovered this authors, we visualize the scenes of their gestation and we enjoy with the plastic arts of their constructive advances

Projective geometry for blueprints

In this note, we generalize the Proj-construction from usual schemes to blue schemes. This yields the definition of projective space and projective varieties over a blueprint. In particular, it is possible to descend closed subvarieties of a projective space to a canonical F_1-model. We discuss this explicitly in case of the Grassmannian Gr(2,4).Comment: 5 pages, 1 figur

Torified varieties and their geometries over F_1

This paper invents the notion of torified varieties: A torification of a scheme is a decomposition of the scheme into split tori. A torified variety is a reduced scheme of finite type over $\Z$ that admits a torification. Toric varieties, split Chevalley schemes and flag varieties are examples of this type of scheme. Given a torified variety whose torification is compatible with an affine open covering, we construct a gadget in the sense of Connes-Consani and an object in the sense of Soul\'e and show that both are varieties over \F_1 in the corresponding notion. Since toric varieties and split Chevalley schemes satisfy the compatibility condition, we shed new light on all examples of varieties over \F_1 in the literature so far. Furthermore, we compare Connes-Consani's geometry, Soul\'e's geometry and Deitmar's geometry, and we discuss to what extent Chevalley groups can be realized as group objects over \F_1 in the given categories.Comment: 34 pages; includes some clarifications of the definitions from the previous versio

An approach to reconcile the agile and CMMI contexts in product line development

Software product line approaches produce reusable platforms and architectures for products set developed by specific companies. These approaches are strategic in nature requiring coordination, discipline, commonality and communication. The Capability Maturity Model (CMM) contains important guidelines for process improvement, and specifies "what" we must have into account to achieve the disciplined processes (among others things). On the other hand, the agile context is playing an increasingly important role in current software engineering practices, specifying "how" the software practices must be addressed to obtain agile processes. In this paper, we carry out a preliminary analysis for reconciling agility and maturity models in software product line domain, taking advantage of both.Postprint (published version

A Security Pattern for Cloud service certification

Cloud computing is interesting from the economic, operational and even energy consumption perspectives but it still raises concerns regarding the security, privacy, governance and compliance of the data and software services offered through it. However, the task of verifying security properties in services running on cloud is not trivial. We notice the provision and security of a cloud service is sensitive. Because of the potential interference between the features and behavior of all the inter-dependent services in all layers of the cloud stack (as well as dynamic changes in them). Besides current cloud models do not include support for trust-focused communication between layers. We present a mechanism to implement cloud service certification process based on the usage of Trusted Computing technology, by means of its Trusted Computing Platform (TPM) implementation of its architecture. Among many security security features it is a tamper proof resistance built in device and provides a root of trust to affix our certification mechanism. We present as a security pattern the approach for service certification based on the use TPM.Universidad de Málaga. Campus de Excelencia Internacional Andalucía Tec

Supporting software maintenance with non-functional information

The paper highlights the role of non functional information (about efficiency, reliability and other software attributes) of software components in software maintenance, focusing in the component programming framework. Non functional information is encapsulated in modules bound to both definitions and implementations of software components and it is written as expressions in a classical programming language. It is shown with an example how this notation supports software maintenance, with the help of an algorithm which is able to select the best implementation of a software component in its context of use, meaning byPeer ReviewedPostprint (published version
