Intentions: a confident-based interaction design for smart spaces

The paradigm of ubiquitous computing has become a reference for the design of Smart Spaces. Current trends in Ambient Intelligence are increasingly related to the scope of Internet of Things. This paradigm has the potential to support cost-effective solutions in the fields of telecare, e-health and Ambient Assisted Living. Nevertheless, ubiquitous computing does not provide end users with a role for proactive interactions with the environment. Thus, the deployment of smart health care services at a private space like the home is still unsolved. This PhD dissertation aims to define a person-environment interaction model to foster acceptability and users confidence in private spaces by applying the concept of user-centred security and the human performance model of seven stages of action.

On some sampling-related frames in U-invariant spaces

This paper concerns the characterization as frames of some sequences in U-invariant spaces of a separable Hilbert space H where U denotes an unitary operator defined on H ; besides, the dual frames having the same form are also found. This general setting includes, in particular, shift-invariant or modulation-invariant subspaces in L2 (R), where these frames are intimately related to the generalized sampling problem. We also deal with some related perturbation problems. In so doing, we need that the unitary operator U belongs to a continuous group of unitary operators.

NFC based remote control of services for interactive spaces

Ubiquitous computing (one person, many computers) is the third era in the history of computing. It follows the mainframe era (many people, one computer) and the PC era (one person, one computer). Ubiquitous computing empowers people to communicate with services by interacting with their surroundings. Most of these so called smart environments contain sensors sensing users’ actions and try to predict the users’ intentions and necessities based on sensor data. The main drawback of this approach is that the system might perform unexpected or unwanted actions, making the user feel out of control. In this master thesis we propose a different procedure based on Interactive Spaces: instead of predicting users’ intentions based on sensor data, the system reacts to users’ explicit predefined actions. To that end, we present REACHeS, a server platform which enables communication among services, resources and users located in the same environment. With REACHeS, a user controls services and resources by interacting with everyday life objects and using a mobile phone as a mediator between himself/herself, the system and the environment. REACHeS’ interfaces with a user are built upon NFC (Near Field Communication) technology. NFC tags are attached to objects in the environment. A tag stores commands that are sent to services when a user touches the tag with his/her NFC enabled device. The prototypes and usability tests presented in this thesis show the great potential of NFC to build such user interfaces.

Identification of pore spaces in 3D CT soil images using a PFCM partitional clustering

Recent advances in non-destructive imaging techniques, such as X-ray computed tomography (CT), make it possible to analyse pore space features from the direct visualisation from soil structures. A quantitative characterisation of the three-dimensional solid-pore architecture is important to understand soil mechanics, as they relate to the control of biological, chemical, and physical processes across scales. This analysis technique therefore offers an opportunity to better interpret soil strata, as new and relevant information can be obtained. In this work, we propose an approach to automatically identify the pore structure of a set of 200-2D images that represent slices of an original 3D CT image of a soil sample, which can be accomplished through non-linear enhancement of the pixel grey levels and an image segmentation based on a PFCM (Possibilistic Fuzzy C-Means) algorithm. Once the solids and pore spaces have been identified, the set of 200-2D images is then used to reconstruct an approximation of the soil sample by projecting only the pore spaces. This reconstruction shows the structure of the soil and its pores, which become more bounded, less bounded, or unbounded with changes in depth. If the soil sample image quality is sufficiently favourable in terms of contrast, noise and sharpness, the pore identification is less complicated, and the PFCM clustering algorithm can be used without additional processing; otherwise, images require pre-processing before using this algorithm. Promising results were obtained with four soil samples, the first of which was used to show the algorithm validity and the additional three were used to demonstrate the robustness of our proposal. The methodology we present here can better detect the solid soil and pore spaces on CT images, enabling the generation of better 2D?3D representations of pore structures from segmented 2D images.

Challenges for future of Natural Spaces of Canary Islands, Spain

The preservation of biodiversity is a fundamental objective of a ll policies related to a more sustainable development in any modern society. The rain forest and pine forests are two unique Canarian ecosystems with high importance to global biodiversity, holding a large number of endemic species and subspecies that is a priority to preserve. In this work the challenges that will face the natural areas of the Canary Islands are studied, as well as their fundamental value for economic and environmental development of the islands.

Vivienda y Revolución. El Concurso entre Camaradas de la OSA, la Sección de Tipificación del Stroykom y la Casa Experimental de Transición Narkomfin (1926-1930) = Housing and Revolution. OSA’s Comradely Competition, Typification Section of the Stroykom and Narkomfin Experimental Transitional House (1926-1930)

La cuestión del asentamiento socialista en la URSS durante la década de 1920 estuvo caracterizada por el objetivo de definir y establecer un estado socialista en términos políticos, sociales y económicos. En este contexto de inestabilidad y cambio, un grupo de arquitectos pertenecientes a la Asociación de Arquitectos Contemporáneos, OSA, y liderado por Moisey Ginzburg, abordó el tema de la vivienda obrera asumiendo la responsabilidad y el compromiso por alcanzar un nuevo orden social. Su misión no consistió únicamente en solucionar el problema del alojamiento para los trabajadores en las grandes ciudades soviéticas, sino en redefinirlo como el marco adecuado para una sociedad sometida a un cambio sin precedentes que, al mismo tiempo y en un proceso dialéctico, debía contribuir a la construcción de esa nueva sociedad. La respuesta dada por la OSA trascendió el diseño inmediato bajo los estándares modernos establecidos en Occidente y tomó forma en un proceso de investigación que habría de prolongarse durante cinco años. Este trabajo, que culminó con la construcción y puesta en crisis de la Casa Narkomfin, se desarrolló en tres aproximaciones sucesivas. La primera, de carácter conceptual, consideró la participación ciudadana, así como de especialistas independientes, formalizándose en el Concurso entre Camaradas convocado por la OSA en 1926. La segunda aproximación al problema de la vivienda obrera se articuló a través de la investigación llevada a cabo por la Sección de Tipificación del Stroykom, esta vez desde premisas científicas y metodológicas. Finalmente, las conclusiones alcanzadas fueron transferidas a la práctica arquitectónica por medio de la construcción de seis Casas Experimentales de Transición, entre las que destacó la Casa Narkomfin. Este último acercamiento, de carácter empírico, ha sido tradicionalmente examinado por los expertos como un hecho aislado. Sin embargo, su estudio debe trascender necesariamente el genio del autor-creador en favor del proceso de investigación al que pertenece. En esta tesis, la Casa Narkomfin no se presenta sólo como el paradigma de vivienda soviética de vanguardia al que estamos acostumbrados, sino como un prototipo que recoge los principios y conclusiones alcanzados en las aproximaciones conceptuales y científicas precedentes. Únicamente desde este punto de vista cobra sentido la consideración de Ginzburg sobre su propio edificio como un medio propositivo y no impositivo: un proyecto concebido como una herramienta de transición hacia una sociedad más avanzada. ABSTRACT The question of mass housing in the USSR during the Twenties was marked by the drive to define and establish a socialist state in political, social and economic terms. In this context of instability and change, a group of architects gathered together under the Association of Contemporary Architects, OSA, led by Moisey Ginzburg, to address the issue of mass housing, thus taking on the responsibility and being committed to creating a new social order. Their quest not only involved solving the problem of housing for workers in large Soviet cities, but also redefining this solution as an appropriate framework for a society undergoing dramatic changes which, at the same time and in a dialectical process, would contribute to the creation of this new society. The solution provided by OSA transcended Modern standards of immediate design set by the West and was the result of a research process that would last five years. This work culminated in the construction of Narkomfin House and its self-criticism, developed in three successive approaches. The first was conceptual, being formalized in the Comradely Competition held by the OSA in 1926 and taking into account the participation of citizens and independent experts. The second approach to the problem of mass housing involved research developed by the Typification Section of the Stroykom, this time under scientific and methodological premises. Finally, the conclusions reached were put in practice with the construction of six Experimental Transitional Houses of which the most notable is Narkomfin House. This third empirical approach has traditionally been examined by scholars in isolation. However, its study must necessarily transcend the genius of the author-creator and involve the research process of which it is part. In this thesis, Narkomfin House is presented not only as the paradigm in Soviet housing avant-garde we are used to, but also as a prototype reflecting the principles and conclusions reached in the preceding conceptual and scientific approaches. Only from this point of view does Ginzburg’s understanding of his own building as a proactive and non-imposed environment make sense: a project conceived as a transition tool towards a more advanced society.

Nonatomic games on Loeb spaces

In the setting of noncooperative game theory, strategic negligibility of individual agents, or diffuseness of information, has been modeled as a nonatomic measure space, typically the unit interval endowed with Lebesgue measure. However, recent work has shown that with uncountable action sets, for example the unit interval, there do not exist pure-strategy Nash equilibria in such nonatomic games. In this brief announcement, we show that there is a perfectly satisfactory existence theory for nonatomic games provided this nonatomicity is formulated on the basis of a particular class of measure spaces, hyperfinite Loeb spaces. We also emphasize other desirable properties of games on hyperfinite Loeb spaces, and present a synthetic treatment, embracing both large games as well as those with incomplete information.

Characterizations of logarithmic Besov spaces in terms of differences, Fourier-analytical decompositions, wavelets and semi-groups.

We work with Besov spaces Bp,q0,b defined by means of differences, with zero classical smoothness and logarithmic smoothness with exponent b. We characterize Bp,q0,b by means of Fourier-analytical decompositions, wavelets and semi-groups. We also compare those results with the well-known characterizations for classical Besov spaces Bp,qs.

On paracompactness, completeness and boundedness in uniform spaces

Recently two new types of completeness in metric spaces, called Bourbaki-completeness and cofinal Bourbaki-completeness, have been introduced in [7]. The purpose of this note is to analyze these completeness properties in the general context of uniform spaces. More precisely, we are interested in how they are related with uniform paracompactness properties, as well as with some kind of uniform boundedness.

Two classes of metric spaces

The class of metric spaces (X,d) known as small-determined spaces, introduced by Garrido and Jaramillo, are properly defined by means of some type of real-valued Lipschitz functions on X. On the other hand, B-simple metric spaces introduced by Hejcman are defined in terms of some kind of bornologies of bounded subsets of X. In this note we present a common framework where both classes of metric spaces can be studied which allows us to see not only the relationships between them but also to obtain new internal characterizations of these metric properties.

On the nullstellensätze for stein spaces and C-analytic sets.

In this work we prove the real Nullstellensatz for the ring O(X) of analytic functions on a C-analytic set X ⊂ Rn in terms of the saturation of Łojasiewicz’s radical in O(X): The ideal I(Ƶ(a)) of the zero-set Ƶ(a) of an ideal a of O(X) coincides with the saturation (Formula presented) of Łojasiewicz’s radical (Formula presented). If Ƶ(a) has ‘good properties’ concerning Hilbert’s 17th Problem, then I(Ƶ(a)) = (Formula presented) where (Formula presented) stands for the real radical of a. The same holds if we replace (Formula presented) with the real-analytic radical (Formula presented) of a, which is a natural generalization of the real radical ideal in the C-analytic setting. We revisit the classical results concerning (Hilbert’s) Nullstellensatz in the framework of (complex) Stein spaces. Let a be a saturated ideal of O(Rn) and YRn the germ of the support of the coherent sheaf that extends aORn to a suitable complex open neighborhood of Rn. We study the relationship between a normal primary decomposition of a and the decomposition of YRn as the union of its irreducible components. If a:= p is prime, then I(Ƶ(p)) = p if and only if the (complex) dimension of YRn coincides with the (real) dimension of Ƶ(p).
