When the virtual influences reality. The conservation project of the toledo gate in ciudad real (Spain)

The Toledo Gate of Ciudad Real, Spain, constructed between the late 13th and early 14th centuries, is the last remaining portion of a once complete medieval city wall. It represents the long history of the city and constitutes its main heritage symbol, dividing the historic city centre from the later 19th and 20th century expansions. In October 2012, the Town Hall and the Montemadrid Foundation started the conservation works to preserve this important monument. The preliminary phase of this project included an in-depth series of scientific studies which were carried out by a multidisciplinary team focusing on archival research, historic investigations, archaeological excavations as well as material composition analysis and main treatment application tests. As a result of these studies a series of virtual 3D models were created to inform, discuss and study the monument. A first digital model permitted visualization of the gate in the 19th century and how the main entrance to the city was integrated as a fundamental part of the city walls. This virtual reconstruction also became an important part of the campaign to raise awareness among the citizens towards a monument that had remained in the shadows for the last century, isolated in a roundabout after the systematic demolition of the city walls in the late 19th century. Over the last three years and as a result of these archaeological and historic investigations and subsequent virtual models, surprisingly new and interesting data were brought to light thus permitting the establishment and corroboration of a new and updated hypothesis of the Toledo Gate that goes beyond the previous ideas. As a result of these studies a new architectural typology with construction techniques of has been suggested. This paper describes how the results of this continuous and interdisciplinary documentation process have benefitted from a computer graphic reconstruction of the gate. It highlights how virtual reconstruction can be a powerful tool for conservation decision making and awareness raising. Furthermore, the interesting results of the final reconstruction hypothesis convinced the technical team responsible for the conservation to alter some aspects of the final project physical interventions in order to focus on some of the features and conclusions discovered through the virtual model study.

Virtual restoration of the sound of the Hispanic Rite

The virtual acoustic reality techniques are powerful tools for the recovery of acoustical heritage of historic buildings. Through the acoustic modeling and auralization techniques it´s possible to reconstruct the sound of disappeared buildings or the ones with significant modifications over the years, knowing the original geometry and the acoustic characteristics of their surfaces. This paper shows the results of a research project whose goal is the virtual recovery of the sound of the Hispanic Rite, the rite celebrated by Christians of the Iberian Peninsula before the imposition of the Roman Rite in the mid-eleventh century. For this purpose, acoustic models of a series of Pre-Romanesque churches were made. These acoustic models represent the churches in their original state, following the reconstruction hypothesis proposed by leading researchers in medieval liturgical archeology. Multichannel anechoic recordings of several pieces of the music of the Hispanic Rite have been carried out using a spherical array composed of 31 microphones. Finally, static and dynamic auralizations have been developed, involving the different liturgical configurations which were usual in this rite.

The Virtual Interactive Relationship Between BIM Project Teams: Effective Communication to aid Collaboration in the Design Process

Building Information Modelling (BIM) provides a shared source of information about a built asset, which creates a collaborative virtual environment for project teams. Literature suggests that to collaborate efficiently, the relationship between the project team is based on sympathy, obligation, trust and rapport. Communication increases in importance when working collaboratively but effective communication can only be achieved when the stakeholders are willing to act, react, listen and share information. Case study research and interviews with Architecture, Engineering and Construction (AEC) industry experts suggest that synchronous face-to-face communication is project teams’ preferred method, allowing teams to socialise and build rapport, accelerating the creation of trust between the stakeholders. However, virtual unified communication platforms are a close second-preferred option for communication between the teams. Effective methods for virtual communication in professional practice, such as virtual collaboration environments (CVE), that build trust and achieve similar spontaneous responses as face-to-face communication, are necessary to face the global challenges and can be achieved with the right people, processes and technology. This research paper investigates current industry methods for virtual communication within BIM projects and explores the suitability of avatar interaction in a collaborative virtual environment as an alternative to face-to-face communication to enhance collaboration between design teams’ professional practice on a project. Hence, this paper presents comparisons between the effectiveness of these communication methods within construction design teams with results of further experiments conducted to test recommendations for more efficient methods for virtual communication to add value in the workplace between design teams.

Emerging strategies for sponsorship on the Internet

Internet sponsorship is a rapidly evolving communications platform at a fledgling stage for sponsorship-linked marketing. The complex and involving nature of the phenomena offers new research opportunities and the potential for innovative marketing strategies. The Internet presents the opportunity to combine aspects of traditional event/activity sponsorship and media sponsorship innovatively and to extend marketing strategy in new directions. This paper presents an overview of emerging Internet sponsorships strategies, identifies virtual and reality sponsorship opportunities, and explores emerging sponsorship extension strategies that relate to media, brand, channel development, consumer experience, and networking. Finally, future directions for researchers and practitioners are suggested.

L'expérience comme mode de détermination des faits dans le procès civil

L'utilisation de l'expérience comme un mode de détermination des faits, c'est-à-dire comme un élément qui comble les lacunes dans l'ensemble des éléments de preuve dans le procès civil, est un thème quelque peu tabou. La doctrine est souvent basée sur la prémisse voulant que le décideur rende une décision uniquement en vertu des éléments de preuve et qu'il doit absolument s'abstenir d'insérer aux constatations quoi que ce soit qui n'est pas présent dans les éléments de preuve. Cette vision est éloignée de la réalité juridique. Dans la première partie, nous allons aborder les principes procéduraux qui empêchent l'utilisation de l'expérience comme mode de détermination des faits. Ce sont le principe de la reconstruction de l'événement du passé, le principe de l'abstraction des connaissances acquises hors du procès et le principe de l'exclusion de la preuve par ouï-dire. Ensuite, nous portons notre attention sur les différents types d'expérience, c'est-à-dire l'expérience profane, divisible en bon sens et sens commun, et l'expérience scientifique, ainsi sur leurs modes de fonctionnement dans le procès civil. La première partie se termine par une brève confrontation des différents types d'expérience avec les principes procéduraux. La deuxième partie est consacré à l'analyse de l'expérience dans trois instruments juridiques: la connaissance d'office, la présomption de fait et le témoignage d'expert. Nous nous intéressons principalement à vérifier si l'expérience fonctionne à l'intérieur de ces instruments juridiques comme mode de détermination des faits et ensuite quelles sont les limites que le droit pose à l'expérience dans ce rôle. L'analyse va confirmer que le principal instrument par lequel l'expérience comme mode de détermination des faits pénètre dans le procès civil est la présomption de fait.

L'Internet et le droit international privé: un mariage boiteux ?

Quiconque aujourd’hui souhaitant profiter des avantages commerciaux d’Internet risque de faire face à une réalité juridique complexe. Qui peut rendre jugement d’un conflit né d’Internet ? Comment faire reconnaître un jugement rendu dans un autre pays ? Ces questions soulèvent beaucoup d’intérêt pour les juristes du cyberespace auqle l’auteur tente de répondre. Par des exemples concrets, notamment l’affaire Yahoo! et celle de Gutnick, l’auteur analyse également les relations entre Internet et le droit international privé. On voit donc les tendances qui se dégagent concernant les actes de dommage, la responsabilité et les victimes sur les réseaux et de quelle façon les cours internationales entendent les régler.

Investigating 'indecent, obscene or pornographic' art : lessons from the Bill Henson controversy

This article considers the manner in which police in Australia investigate art that is putatively indecent, obscene or pornographic. It does so by examining the recent Bill Henson controversy and other similar instances where art and the criminal law have collided. This analysis will demonstrate that under Australian law there is little or no chance of a successful criminal prosecution for obscenity, indecency or pornography. Consequently, it is argued that police investigative procedures must take account of this legal reality. To this end a reform proposal is offered: upon receiving a complaint of this nature, police must — as a matter of internal procedure or law — immediately refer the impugned artwork to the Classification Board for a classification decision before they commence a formal investigation.

Transparencia presupuestaria en los gobiernos municipales de Brasil por medio de internet: el caso de Piracicaba São Paulo

This article seeks to assess the extent to which the municipality of Piracicaba (in the Brazilian state of São Paulo) has practiced Municipal Budgetary Transparency in Internet (TOM Web), as conceptualized by Pires (2011). The TOM Web is based on definitions used by the IMF and the OECD, and the characteristics of the Brazilian institutional and legal reality.

Inclusão e cidadania digital no Brasil: a (des) articulação das políticas públicas

The incipient but quickly expansion action on the Information and Communications Technologies (ICT) in Africa it is now just having different impact on these societies. One of these relates bear on how users are identified with these tools. Just like that we find individuals identify as bloggers, twitter followers or cyber activist. This contribution analyzes the Senegal’s fact where a successful use of social nets and web 2.0 tools experience (at least in repercussion) as social and political involvement while presidential elections in 2012 is tied to come back an identity: Cyber activist. Senegalese circumstance shows us how this identity has a personal and assertiveness dimension as well collective aspects of belonging to a community. One as much as the other, show us personal traits in contrast to previous beliefs, basically because it fuse and confuse virtual and reality. Due to dynamics from expanding technology, this identity is youthful and urban, but not only. This situation creates new dynamics at least in this affected group. For this reason, besides knowing emergence and evolution of this fact, it raises some of the involvement in social and political involvement from groups traditionally “invisible”. Beyond the new social behavior there are new changes in the rules of the game in order to start new social revolution.

Multi-textured 3D humanoid reconstruction through passive and active automatic techniques = Reconstrucción de humanoides 3D multi-texturados mediante técnicas pasivas y activas automáticas

The proliferation of video games and other applications of computer graphics in everyday life demands a much easier way to create animatable virtual human characters. Traditionally, this has been the job of highly skilled artists and animators that painstakingly model, rig and animate their avatars, and usually have to tune them for each application and transmission/rendering platform. The emergence of virtual/mixed reality environments also calls for practical and costeffective ways to produce custom models of actual people. The purpose of the present dissertation is bringing 3D human scanning closer to the average user. For this, two different techniques are presented, one passive and one active. The first one is a fully automatic system for generating statically multi-textured avatars of real people captured with several standard cameras. Our system uses a state-of-the-art shape from silhouette technique to retrieve the shape of subject. However, to deal with the lack of detail that is common in the facial region for these kind of techniques, which do not handle concavities correctly, our system proposes an approach to improve the quality of this region. This face enhancement technique uses a generic facial model which is transformed according to the specific facial features of the subject. Moreover, this system features a novel technique for generating view-independent texture atlases computed from the original images. This static multi-texturing system yields a seamless texture atlas calculated by combining the color information from several photos. We suppress the color seams due to image misalignments and irregular lighting conditions that multi-texturing approaches typically suffer from, while minimizing the blurring effect introduced by color blending techniques. The second technique features a system to retrieve a fully animatable 3D model of a human using a commercial depth sensor. Differently to other approaches in the current state of the art, our system does not require the user to be completely still through the scanning process, and neither the depth sensor is moved around the subject to cover all its surface. Instead, the depth sensor remains static and the skeleton tracking information is used to compensate the user’s movements during the scanning stage. RESUMEN La popularización de videojuegos y otras aplicaciones de los gráficos por ordenador en el día a día requiere una manera más sencilla de crear modelos virtuales humanos animables. Tradicionalmente, estos modelos han sido creados por artistas profesionales que cuidadosamente los modelan y animan, y que tienen que adaptar específicamente para cada aplicación y plataforma de transmisión o visualización. La aparición de los entornos de realidad virtual/mixta aumenta incluso más la demanda de técnicas prácticas y baratas para producir modelos 3D representando personas reales. El objetivo de esta tesis es acercar el escaneo de humanos en 3D al usuario medio. Para ello, se presentan dos técnicas diferentes, una pasiva y una activa. La primera es un sistema automático para generar avatares multi-texturizados de personas reales mediante una serie de cámaras comunes. Nuestro sistema usa técnicas del estado del arte basadas en shape from silhouette para extraer la forma del sujeto a escanear. Sin embargo, este tipo de técnicas no gestiona las concavidades correctamente, por lo que nuestro sistema propone una manera de incrementar la calidad en una región del modelo que se ve especialmente afectada: la cara. Esta técnica de mejora facial usa un modelo 3D genérico de una cara y lo modifica según los rasgos faciales específicos del sujeto. Además, el sistema incluye una novedosa técnica para generar un atlas de textura a partir de las imágenes capturadas. Este sistema de multi-texturización consigue un atlas de textura sin transiciones abruptas de color gracias a su manera de mezclar la información de color de varias imágenes sobre cada triángulo. Todas las costuras y discontinuidades de color debidas a las condiciones de iluminación irregulares son eliminadas, minimizando el efecto de desenfoque de la interpolación que normalmente introducen este tipo de métodos. La segunda técnica presenta un sistema para conseguir un modelo humano 3D completamente animable utilizando un sensor de profundidad. A diferencia de otros métodos del estado de arte, nuestro sistema no requiere que el usuario esté completamente quieto durante el proceso de escaneado, ni mover el sensor alrededor del sujeto para cubrir toda su superficie. Por el contrario, el sensor se mantiene estático y el esqueleto virtual de la persona, que se va siguiendo durante el proceso, se utiliza para compensar sus movimientos durante el escaneado.
