A realidade virtual na humanidade atual

Virtual Reality it's present in our personal and professional daily life. Currently it comes been tested in many parameters. An example is, as an intervention mode related to healthy and rehabilitation field ( since phobias to physical problems ) due to dynamic interactive between human being and virtual reality, was able to be designed by a hardware and software integrated system. His appearance was in 1950s, through NASA's flight simulators in order to train astronauts in epoch (TORI et al.,2006).Subsequently, this began to expand to entertainment industry, where due to consumerism, only increasing his capacity to become so much more realist and reliable with the real environment. Because of this, beyond of your capacity be accessible which is low-cost, was used in scientific researches (motor area, physical aptitudes, cognitive, health, among others). The projected interactivity in this system type, in general, seek act according to people answers about the elements of virtual reality. Using the capacity that the reality is able to act of integrated way for human being. Following these concepts about virtual reality, the present study of literature revision, it comes as an purpose see humanity development. Since its birth, going on that point until your actuation and direct and indirect interplay in today's society from maturational form. Taking the concept of researchers' theory like Piaget. Following this line, the study will analyse how virtual reality might come to modify and act in social construction of society nowadays

External temporal organization in biological rhythms

This paper is intended as a proposition of a new concept in the field of chronobiology, External Temporal Organization, a notion complementary to that of the Internal Temporal Organization. We will try to explain the possibility that a set of external elements, that occur in a particular order, can act together as a single synchronizing element of the circadian system. We will see that this is not a zeitgeber, in the classic sense, but a much more complex factor, consisting of several elements that appear in the real environment at different times ( phases), constituting as a whole a powerful temporal frame, closer to the way the stimuli occur in the natural environment, in which the entrainment does not take place just in a specific time of the day.

Studio e sviluppo di sistemi RFID in banda UHF

The recent widespread diffusion of radio-frequency identification (RFID) applications operating in the UHF band has been supported by both the request for greater interrogation ranges and greater and faster data exchange. UHF-RFID systems, exploiting a physical interaction based on Electromagnetic propagation, introduce many problems that have not been fully explored for the previous generations of RFID systems (e.g. HF). Therefore, the availability of reliable tools for modeling and evaluating the radio-communication between Reader and Tag within an RFID radio-link are needed. The first part of the thesis discuss the impact of real environment on system performance. In particular an analytical closed form formulation for the back-scattered field from the Tag antenna and the formulation for the lower bound of the BER achievable at the Reader side will be presented, considering different possible electromagnetic impairments. By means of the previous formulations, of the analysis of the RFID link operating in near filed conditions and of some electromagnetic/system-level co-simulations, an in-depth study of the dimensioning parameters and the actual performance of the systems will be discussed and analyzed, showing some relevant properties and trade-offs in transponder and reader design. Moreover a new low cost approach to extend the read range of the RFID UHF passive systems will be discussed. Within the scope to check the reliability of the analysis approaches and of innovative proposals, some reference transponder antennas have been designed and extensive measurement campaign has been carried out with satisfactory results. Finally, some commercial ad-hoc transponder for industrial application have been designed within the cooperation with Datalogic s.p.a., some guidelines and results will be briefly presented.

Surface layer formation in polymer melts and in solutions

In this work the surface layer formation in polymer melts and in polymer solutions have been investigated with the atomic force microscope (AFM). In polymer melts, the formation of an immobile surface layer results in a steric repulsion, which can be measured by the AFM. From former work it is know, that polydimethyl siloxane (PDMS) forms a stable surface layer for molecular weights above 12 kDa. In the present thesis, polyisoprene (PI) was investigated apart from PDMS, by a)measuring the steric surface interactions and b)measuring the surface slip in hydrodynamic experiments. If a polymer flows over a surface, the flow velocity at the surface is larger then zero. If case of a surface layer formation the flow plane changes to the top of the adsorbed layer and the surface slip is reduced to zero. By measuring the surface slip in hydrodynamic experiments, it is therefore possible to determine the presence of a stable surface layer. The results show no stable repulsion for PI and only a small decrease of the surface slip. This indicates that PI does not form a stable surface layer, but is only adsorbed weakly to the surface. Furthermore for 8 kDa PDMS the timescale of the formation of a surface layer was investigated by changing themaximal force the tip applied to the surface. With a repulsive force present, applying a higher force than 15 nN resulted in a destruction of the surface layer, indicated by attractive forces. Reducing the applied force below 15 nN then resulted in an increase of the repulsion to the former state during one minute, thus indicating that a surface layer can be formed within one minute even under the influence of continuous measurements. As a next step, mixtures of two PDMS homopolymers with different chain lengths have been investigated. The aim was to verify theoretical predictions that shorter chains should predominate at the surface due to their smaller loss in conformational entropy. The measurements where done in dependence of the volume fractions of short and long chain PMDS. The results confirmed the short chain dominance for all mixtures with less then 90 vol.% long chain PDMS. Surface layer formation in solution was investigated for superplasticizers which are industrially used as an additive to cement. They change the surface interaction between the cement grains from attractive to repulsive and the freshlymixed cement paste therefore becomes liquid. The aimin this part of the thesis was, to investigate cement particle interactions in a close to real environment. Therefore calcium silicate hydrate phases have been precipitated onto an AFM tip and onto a calcite crystal and the interaction between these surfaces have beenmeasured with and without addition of superplasticizers. The measurements confirmed the change from attraction to repulsion upon addition of superplasticizers. The repulsive steric interaction increased with the length of the sidechain of the superplasticizer, and the dependence of the range of the steric interactions on the sidechain length indicated that the sidechains are in a coiled conformation.

Ricerca e applicazione di metodologie ecotossicologiche nel monitoraggio di ambienti marino-costieri: Sviluppo di nuovi bioassay e biomarker

Obiettivo del lavoro è stato lo sviluppo e la validazione di nuovi bioassay e biomarker quali strumenti da utilizzare in un approccio ecotossicologico integrato per il biomonitoraggio di ambienti marino-costieri interessati da impatto antropico negli organismi che vivono in tali ambienti. L’ambiente reale impiegato per l’applicazione in campo è la Rada di Augusta (Siracusa, Italia). Una batteria di bioassay in vivo e in vitro è stata indagata quale strumento di screening per la misura della tossicità dei sedimenti. La batteria selezionata ha dimostrato di possedere i requisiti necessari ad un applicazione di routine nel monitoraggio di ambienti marino costieri. L’approccio multimarker basato sull’impiego dell’organismo bioindicatore Mytilus galloprovincialis in esperimenti di traslocazione ha consentito di valutare il potenziale applicativo di nuovi biomarker citologici e molecolari di stress chimico parallelamente a biomarker standardizzati di danno genotossico ed esposizione a metalli pesanti. I mitili sono stati traslocati per 45 giorni nei siti di Brucoli (SR) e Rada di Augusta, rispettivamente sito di controllo e sito impattato. I risultati ottenuti supportano l’applicabilità delle alterazioni morfometriche dei granulociti quale biomarker di effetto, direttamente correlato allo stato di salute degli organismi che vivono in un dato ambiente. Il significativo incremento dell’area dei lisosomi osservato contestualmente potrebbe riflettere un incremento dei processi degradativi e dei processi autofagici. I dati sulla sensibilità in campo suggeriscono una valida applicazione della misura dell’attività di anidrasi carbonica in ghiandola digestiva come biomarker di stress in ambiente marino costiero. L’utilizzo delle due metodologie d’indagine (bioassay e biomarker) in un approccio ecotossicologico integrato al biomonitoraggio di ambienti marino-costieri offre uno strumento sensibile e specifico per la valutazione dell’esposizione ad inquinanti e del danno potenziale esercitato dagli inquinanti sugli organismi che vivono in un dato ambiente, permettendo interventi a breve termine e la messa a punto di adeguati programmi di gestione sostenibile dell’ambiente.

Exploring Urban Environments Using Virtual and Augmented Reality

In this paper, we propose the use of specific system architecture, based on mobile device, for navigation in urban environments. The aim of this work is to assess how virtual and augmented reality interface paradigms can provide enhanced location based services using real-time techniques in the context of these two different technologies. The virtual reality interface is based on faithful graphical representation of the localities of interest, coupled with sensory information on the location and orientation of the user, while the augmented reality interface uses computer vision techniques to capture patterns from the real environment and overlay additional way-finding information, aligned with real imagery, in real-time. The knowledge obtained from the evaluation of the virtual reality navigational experience has been used to inform the design of the augmented reality interface. Initial results of the user testing of the experimental augmented reality system for navigation are presented.

Solución para la delegación de identidad en Sistemas de Gestión de Identidad paneuropeos basada en infraestructuras de certificación y lenguajes formales de asertos de seguridad

La estrategia i2010 de la UE tiene como objetivo garantizar el liderazgo europeo en materia de TIC y poner los beneficios de la Sociedad de la Información al servicio de la economía, la sociedad y la calidad de vida personal, teniendo presente que los éxitos de Europa hasta la fecha se han basado en favorecer la competencia leal en los mercados de las telecomunicaciones y crear un mercado sin fronteras para contenidos y medios de comunicación digitales. En esta línea, la Comisión Europea ha establecido que los distintos estados miembros deben contribuir activamente al desarrollo y uso seguro de los servicios telemáticos entre sus ciudadanos. Más concretamente, atribuye a las Administraciones Públicas, tanto a nivel nacional, regional como local, un papel dinamizador de la Sociedad de la Información que les obliga a ofrecer paulatinamente todos los actos administrativos a los ciudadanos a través de Internet. Como primer paso para el uso seguro de los servicios telemáticos que ofrecen las instituciones públicas se hace preciso dotar a los ciudadanos de una identidad digital que les permita identificarse ante un Proveedor de Servicio o ante otros ciudadanos de manera inequívoca. Por esta razón, la mayoría de países europeos – y otros en el resto del mundo – están promoviendo, sistemas fiables de gestión de identidad electrónica (eIDM), de tal manera que los ciudadanos, las empresas y departamentos gubernamentales (incluso en Estados miembros diferentes) pueden identificar y certificar sus operaciones con precisión, rapidez y sencillez. Sin embargo, la gestión de esta identidad por las Administraciones Públicas supone un importante desafío, acentuado cuando se hace necesaria la interoperabilidad entre Administraciones de diferentes países, puesto que personas y entidades tienen credenciales de identificación diferentes en función de su propio marco jurídico nacional. Consciente del problema, en la Unión Europea se han puesto en marcha una serie de proyectos con el objetivo de conseguir la interoperabilidad de los eIDMs entre las instituciones públicas de diferentes Estados miembros. A pesar de ello, las soluciones adoptadas hasta la fecha son insuficientes porque no prevén todos los posibles casos de interacción del usuario con las instituciones. En concreto, no tienen en cuenta un aspecto muy importante que se ofrece en los distintos sistemas jurídicos nacionales, a saber, la delegación de la identidad, mediante la cual un ciudadano puede autorizar a otro para que actúe en su nombre para acceder a determinados servicios prestados por las instituciones públicas. En esta tesis se realizan un conjunto de aportaciones que dan solución a distintos aspectos de los problemas planteados y que, de forma conjunta, permiten la interoperabilidad y la delegación de identidad en determinados Sistemas de Gestión de Identidad aplicados al entorno de las Administraciones Públicas. En el caso de la delegación, se ha definido un sistema de delegación dinámica de identidad entre dos entidades genéricas que permite solucionar el problema del acceso delegado a los servicios telemáticos ofrecidos por las Administraciones Públicas. La solución propuesta se basa en la generación de un token de delegación, constituido a partir de un Certificado Proxy, que permite a la entidad que delega establecer la delegación de identidad en otra entidad en base a un subconjunto de sus atributos como delegador, estableciendo además, en el propio token de delegación, restricciones en el conjunto de servicios accesibles a la entidad delegada y el tiempo de validez de la delegación. Adicionalmente, se presentan los mecanismos necesarios tanto para poder revocar un token de delegación como para comprobar sin un token de delegación ha sido o no revocado. Para ello se propone una solución para la identificación unívoca de tokens de delegación y la creación de una nueva entidad denominada Autoridad de Revocación de Tokens de Delegación. Entre las características del sistema de delegación propuesto destaca el que es lo suficientemente seguro como para ser utilizado en el entorno de la Administración Pública, que no requiere el uso de mecanismos off‐line para la generación de la delegación y que se puede realizar la delegación de forma instantánea y sin la necesidad de trámites complejos o la participación de un elevado número de entidades. Adicionalmente, el token de delegación propuesto es perfectamente integrable en las infraestructura de clave pública actual lo que hace que, dado que gran parte de las Administraciones Públicas europeas basan sus sistemas de identidad digital en el uso de la PKI y certificados de identidad X.509, la solución pueda ser puesta en marcha en un entorno real sin necesidad de grandes cambios o modificaciones de comportamiento. En lo referente a la interoperabilidad, se realiza un análisis exhaustivo y la correspondiente evaluación de las principales propuestas de Sistemas de Gestión de Identidad orientados a conseguir la interoperabilidad realizadas hasta la fecha en el marco de la Unión Europea y se propone, a alto nivel, una arquitectura de interoperabilidad para la gestión de identidad en las Administraciones Públicas. Dicha arquitectura es lo suficientemente genérica como para poder ser aplicada tanto en el entorno pan‐Europeo como en los entornos nacionales, autonómicos y locales, de tal forma que la interoperabilidad en la gestión de la identidad esté garantizada en todos los niveles de la Administración Pública. Por último, mediante la integración de la solución de delegación dinámica de identidad y la arquitectura de interoperabilidad propuestas se presenta una solución al problema de la delegación en un escenario pan‐Europeo de gestión de identidad, dando lugar a una arquitectura global de interoperabilidad pan‐Europea con soporte a la delegación de identidad. SUMMARY The i2010 European Union Plan aims to ensure European leadership in ICT and to promote the positive contribution that information and communication technologies can make to the economic, social and personal quality of life, bearing in mind that, to date, success in Europe has been based on promoting fair competition in telecommunications markets and on creating a borderless market for contents and digital media. In this line, the European Commission has established that the different member states should contribute actively to the development and secure use of telematic services among their citizens. More specifically, it is attributed to national, regional and local Public Administrations to have a supportive role of the Information Society, requiring them to gradually provide the citizens with Internet‐based access to all administrative procedures acts. As a first step for the secure use of telematic services offered by public institutions, it is necessary to provide the citizens with a digital identity to enable them to identify themselves unequivocally to a Service Provider or to other citizens. For this reason, most European countries ‐ and others in the rest of the world ‐ are promoting reliable systems for managing electronic identity (eIDM), so that citizens, businesses and government departments (even in different Member States) can identify and certify their operations with precision, speed and simplicity. However, the identity management by Public Administrations is a major challenge that becomes more difficult when interoperability between administrations of different countries is needed, due to the fact that individuals and entities have different identification credentials according to their own national legal framework. Aware of the problem, the European Union has launched a series of projects with the aim of achieving interoperability of eIDMs between public institutions of different Member States. However, the solutions adopted to date are insufficient because they do not foresee all possible cases of user interaction with the institutions. In particular, solutions do not take into account a very important aspect that is offered in different national legal systems, namely, the delegation of identity, by which a citizen can authorize another to act on his/her behalf to access certain services provided by public institutions. In this thesis a collection of contributions that provide solution to different aspects of the aforementioned problems are carried out. The solutions, in global, enable interoperability and identity delegation in some of the Identity Management Systems applied to Public Administration environment. In the case of delegation, a dynamic identity delegation system between generic entities is defined. This system makes it possible to solve the problem of delegated access to telematic services offered by Public Administrations. The proposed solution is based on the generation of a piece of information called delegation token. This delegation token, derived from a Proxy Certificate, allows the establishment of identity delegation by an entity that delegates (delegator) in other entity (delegatee) making use of a subset of delegator attributes. It also establishes restrictions on services that can be used by the delegated entity and the expiry date of delegation. In addition to this, the mechanisms necessary to revoke and check the revocation status of a delegation token are presented. To do this, a solution to univocally identify delegation tokens and the creation of a completely new entity, called Token Delegation Revocation Authority, are proposed. The most remarkable characteristics of the proposed delegation system are its security, enough for it to be used in the Public Administration environment, the fact that it does not require off‐line processes in order to generate the delegation, and the possibility of performing the delegation instantaneously and without neither complex processes nor the intervention of a large number of entities. The proposed delegation token can be completely incorporated into current Public Key Infrastructure (PKI). Thus, since most of the European Public Administrations base their digital identity systems on PKI and X.509 identity certificates, the solution can be adopted in a real environment without great changes or performance modifications. Regarding interoperability, an exhaustive analysis and evaluation of most significant proposals on Identity Management Systems that aim to achieve interoperability carried out in the European Union framework until now are performed. A high level identity management interoperability architecture for Public Administrations is also proposed. This architecture is sufficiently generic to be applied to both pan‐European environment and national, regional or local environments, thus interoperability in identity management at all Public Administration levels is guaranteed. Finally, through the integration of the proposed dynamic identity delegation solution and the high level interoperability architecture, a solution to the problem of identity delegation in a pan‐European identity management environment is suggested, leading to a pan‐European global interoperability architecture with identity delegation support.

A Visual AGV-Urban Car using Fuzzy Control

The goal of the work described in this paper is to develop a visual line guided system for being used on-board an Autonomous Guided Vehicle (AGV) commercial car, controlling the steering and using just the visual information of a line painted below the car. In order to implement the control of the vehicle, a Fuzzy Logic controller has been implemented, that has to be robust against curvature changes and velocity changes. The only input information for the controller is the visual distance from the image center captured by a camera pointing downwards to the guiding line on the road, at a commercial frequency of 30Hz. The good performance of the controller has successfully been demonstrated in a real environment at urban velocities. The presented results demonstrate the capability of the Fuzzy controller to follow a circuit in urban environments without previous information about the path or any other information from additional sensors

Desarrollo de una guía de aprendizaje para el manejo del entorno de CAD IspLEVER

En este proyecto se analizan las características y el ciclo de diseño asociado al entorno de CAD IspLEVER, de Lattice Semiconductor, con la finalidad de evaluar su adecuación a la docencia relacionada con la ingeniería de sistemas digitales cableados. En base a este estudio se realiza una guía del manejo de las diferentes herramientas que se integran en el entorno. Además, se realiza la caracterización de una serie de familias de dispositivos del fabricante Lattice Semiconductor que pudiera servir de apoyo a la hora de elegir un dispositivo de este fabricante para la realización de un determinado diseño. Para dar comienzo a la realización del estudio del entorno y de las herramientas que integra IspLEVER, se procedió a la familiarización con el marco de trabajo. Esta familiarización se realizó, en un principio, a través de la lectura de la documentación ofrecida por el fabricante en su página web, http://www.latticesemi.com. Tras esta lectura, que sirvió para tener una primera visión de las características de la herramienta, se procedió a la descarga del paquete de instalación; el fabricante ofrece una versión de evaluación que expira a los 12 meses. Una vez descargado, se instaló y para terminar con los preparativos, se pasó el procedimiento de obtención de la licencia. Con ello se consiguió tener el software preparado para su utilización. A continuación se emplearon horas de trabajo para, sin documentación alguna, tratar de crear diseños; con este trabajo se pretendía detectar lo intuitivo que resulta el entorno cuando se tienen conocimientos de herramientas de CAD electrónico. Tras esta primera toma de contacto con el entorno real, se procedió al estudio de las diferentes opciones que ofrece para la realización de diseños, ya sean lógicos o físicos. Además del estudio de todas las posibilidades que ofrece el entorno, el trabajo se focalizó en la detección y comparación de las distintas opciones que ofrece para realizar una misma tarea, como ocurre con la asignación de pines o con la revisión de los resultados de una simulación, entre otras. Entrelazado con el estudio de las opciones que ofrece el entorno, se realizó el estudio de las distintas herramientas de trabajo integradas en el mismo. Una vez estudiado el entorno y las herramientas, se procedió a la realización del tutorial. Se capturaron todas las imágenes que se consideraron apropiadas para que al alumno le resultase cómodo y fácil seguir todas las indicaciones que el tutorial ofrece, para la realización de un ciclo de diseño lógico completo. Tras la realización del tutorial, se procedió a revisar la amplia documentación que el fabricante ofrece de cada una de las distintas familias de dispositivos que fabrica. El fin de esta revisión no fue otro que realizar una caracterización de las distintas familias, que pudiera servir de apoyo a la hora de elegir un dispositivo de este fabricante para la realización de un determinado diseño. Este estudio de las familias de dispositivos del fabricante, también se realizó para detectar qué familia de dispositivos era la más idónea para incluir uno de sus miembros en una hipotética placa de prototipado, para la realización de prácticas de laboratorio. ABSTRACT. This project consists in the analysis of the characteristics and the design cycle associated with the IspLEVER environment of CAD, by Lattice Semiconductor. The objective of that analysis is to evaluate their suitability for teaching engineering related to wired digital systems. Based on this analysis a guide was made for managing the different tools that are integrated into the environment. In addition, the characterization of several families by the manufacturer Lattice Semiconductor was made, with the objective that it could be used to support the choice of a Lattice’s device to perform a certain design. To start the IspLEVER environment and tools study, I began with a familiarization with the environment. This familiarization consisted in a study of the manufacturer documentation offered in their web page, http://www.latticesemi.com. After that, I had a general view about the characteristics of the environment and environment tools. Then I continued downloading the installation package. The manufacturer offers an evaluation version that expires in the period of one year. After that download, the environment was installed. Finally, the licensing procedure was followed to finish with the preparations. Then, the software was prepared for its utilization. Following, several work hours were wasted without documentation, trying to create designs. This work has been to identify how intuitive the environment is when you have knowledge of electronic CAD tools. After this first point of contact with the real environment, I proceeded to study different offered options, by the manufacturer, for the realization of either logical or physical designs. In addition to studying all the possibilities offered by the environment, the work is focused on the detection and comparison of the various options offered to perform the same task, as with the pin assignment or reviewing the results of a simulation… At the same time, the environment tools were studied. At this point, I began creating the tutorial. I captured all the figures that I consider important to make it easy to the students. The tutorial contains a complete logical design cycle. When the tutorial was finished, I started to review the manufacturer documentation about each devices family. The purpose of this review was to characterize the different families to support the device selection in future designs. Another purpose of that characterization was focused on the detection of the best family to include one of its members in a prototyping board for conducting laboratory practices.

A knowledge based framework to support active aging at home based environments

Information and Communication Technologies can support Active Aging strategies in a scenario like the Smart Home. This paper details a person centered distributed framework, called TALISMAN+, whose aim is to promote personal autonomy by taking advantage of knowledge based technologies, sensors networks, mobile devices and internet. The proposed solution can support an elderly person to keep living alone at his house without being obliged to move to a residential center. The framework is composed by five subsystems: a reasoning module that is able to take local decisions at home in order to support active aging, a biomedical variables telemonitorisation platform running on a mobile device, a hybrid reasoning middleware aimed to assess cardiovascular risk in a remote way, a private vision based sensor subsystem, and a secure telematics solution that guarantees confidentiality for personal information. TALISMAN+ framework deployment is being evaluated at a real environment like the Accessible Digital Home.
