    [EN] Despite the increasing number of three-dimensional (3D) model portals and online repositories catering for digital heritage scholars, students and interested members of the general public, there are very few recent academic publications that offer a critical analysis when reviewing the relative potential of these portals and online repositories. Solid reviews of the features and functions they offer are insufficient; there is also a lack of explanations as to how these assets and their related functionality can further the digital heritage (and virtual heritage) field, and help in the preservation, maintenance, and promotion of real-world 3D heritage sites and assets. What features do they offer? How could their feature list better cater for the needs of the GLAM (galleries, libraries, archives and museums) sector? This article’s priority is to examine the useful features of 8 institutional and 11 commercial repositories designed specifically to host 3D digital models. The available features of their associated 3D viewers, where applicable, are also analysed, connecting recommendations for future-proofing with the need to address current gaps and weaknesses in the scholarly field of 3D digital heritage. Many projects do not address the requirements stipulated by charters, such as access, reusability, and preservation. The lack of preservation strategies and examples highlights the oxymoronic nature of virtual heritage (oxymoronic in the sense that the virtual heritage projects themselves are seldom preserved). To study these concerns, six criteria for gauging the usefulness of the 3D repositories to host 3D digital models and related digital assets are suggested. The authors also provide 13 features that would be useful additions for their 3D viewers.[ES] A pesar del creciente número de portales de modelos tridimensionales (3D) y repositorios en línea que atienden a los estudiosos del patrimonio digital, a los estudiantes y al público en general, hay muy pocas publicaciones académicas recientes que analizan de forma crítica el potencial relativo de esos portales y repositorios en línea. Tampoco hay suficientes revisiones críticas de las características y funciones que ofrecen, ni muchas explicaciones sobre la forma en que estos activos y su funcionalidad pueden impulsar en el campo del patrimonio digital (y el patrimonio virtual), y ayudar a preservar, mantener y promocionar los sitios y activos del patrimonio 3D del mundo real. ¿Qué características ofrecen? ¿Cómo podría su lista de características satisfacer mejor las necesidades del sector GLAM (galerías, bibliotecas, archivos y museos)? La prioridad de este artículo es examinar las características útiles de 8 depósitos institucionales y 11 comerciales diseñados específicamente para albergar modelos digitales en 3D. También son examinadas las características disponibles de su visores 3D asociados, cuando sea aplicable, y ello conecta con lo recomendado sobre las necesidades futuras y mejoradas para abordar las lagunas y debilidades en el campo académico del patrimonio digital 3D. Muchos proyectos no estudian los requisitos estipulados en las cartas, como son los factores de acceso, la reutilización y la preservación. La escasez de estrategias y ejemplos de preservación pone de relieve el carácter oximorónico del patrimonio virtual (oximorónico en el sentido de que los propios proyectos de patrimonio virtual se preservan con muy poca frecuencia). Para hacer frente a estas preocupaciones, se sugieren seis criterios para calibrar la utilidad de los repositorios 3D para albergar modelos digitales 3D y activos digitales relacionados. Los autores también proporcionan 13 características adicionales que serían útiles en los visores 3D.Champion, E.; Rahaman, H. (2020). Survey of 3D digital heritage repositories and platforms.

    On Finding a Defect-free Component in Nanoscale Crossbar Circuits

    AbstractWe propose a technique for the analysis of manufacturing yield of nano-crossbar architectures for different values of defect percentage and crossbar-size. We provide an estimate of the minimum-size crossbar to be fabricated wherein a defect-free crossbar of a given size can always be found with a guaranteed yield. Our technique is based on logical merging of two defective rows (or two columns) that emulate a defect-free row (or column). Experimental results show that the proposed method provides higher defect-tolerance compared to that of previous techniques

    Holographic prism projection: extinction rebellion & energy futures on sci-fi television

    This study in media practice provides insights on video production for holographic prism projection, which has become more accessible as smart flat screens have become more available. The study reflects on the experiences of producing, installing and viewing a documentary video projected via holographic prism, titled ‘FarNearFutureNow.’ Engaging the participation of Extinction Rebellion (XR) members, this university-funded production included recording and combining interview footage with energy policy texts in the visual style of the hologram scene from Star Wars, the 1977 science-fiction film. With viewer co-experience, environmental politics and legacies of colonialism in mind, we produced a 5-minute video and prism projection system for public exhibition. FarNearFutureNow was produced through collective processes of gathering, assembling, reviewing, storyboarding, scripting and editing interview footage and other recordings as well as testing and fabricating installation materials. These production processes enabled us to understand the affordances of creative darkness in holographic production for disassociating and recombining visual elements. The hologram’s disassociated focus on a single object proved useful in drawing audience attention and for assembling non-fiction elements in sequences referencing popular fiction. It is also useful for showing radically different visual scales in sequence, and for simultaneously juxtaposing audio and visual scales

    The Scholarly Rewards and Tragic Irony of 3D Models in Virtual Heritage Discourse

    No full text
    To validate the hypothesis that a virtual heritage papers are reliant on providing scholarly argumentation based on 3D models, and convenient access is provided to these models where relevant, this study reviewed 264 articles form the last three available proceedings of major digital heritage events and conferences (14 in total). The findings revealed this was not the case, few contain references to accessible 3D models. We discuss why this may be so, and we outline recommendations for ensuring that virtual heritage 3D models can be preserved and accessed

    "The book, Caron Nanotube and Graphene Nanoribbon Interconnects, authored by Drs. Debapraad Das and Hafizur Rahaman serves as a good source of material on CNT and GNR interconnects for readers who wish to get into this area and also for practicing engineers who would like to be updated in advances of this field."-Prof. Ashok Srivastava, Louisiana State University, Baton Rouge, USA"Mathematical analysis included in each and every chapter is the main strength of the materials. ... The book is very precise and useful for those who are working in this area. ... highly focused, very compact, and easy to apply. ... This book depicts a detailed analysis and modelling of carbon nanotube and graphene nanoribbon interconnects. The book also covers the electrical circuit modelling of carbon nanotubes and graphene nanoribbons."-Prof. Chandan Kumar Sarkar, Jadavpur University, Kolkata, India
