In this paper two improvements for the Hypervideo platform, used to represent augmented reality on Interactive TVs thanks to the hypervideo concept, are presented: the introduction of a second-screen application to the platform, enabling the user to obtain the additional information on its handheld device and delivering the video track through the broadcast channel, thanks to the HbbTV capability.
The Symbiotic Genomes Database (SymGenDB; http://symbiogenomesdb.uv.es/) is a public resource of manually curated associations between organisms involved in symbiotic relationships, maintaining a catalog of completely sequenced/finished bacterial genomes exclusively. It originally consisted of three modules where users could search for the bacteria involved in a specific symbiotic relationship, their genomes and their genes (including their orthologs). In this update, we present an additional module that includes a representation of the metabolic network of each organism included in the database, as Directed Acyclic Graphs (MetaDAGs). This module provides unique opportunities to explore the metabolism of each individual organism and/or to evaluate the shared and joint metabolic capabilities of the organisms of the same genera included in our listing, allowing users to construct predictive analyses of metabolic associations and complementation between systems. We also report a ~25% increase in manually curated content in the database, i.e. bacterial genomes and their associations, with a final count of 2328 bacterial genomes associated to 498 hosts. We describe new querying possibilities for all the modules, as well as new display features for the MetaDAGs module, providing a relevant range of content and utility. This update continues to improve SymGenDB and can help elucidate the mechanisms by which organisms depend on each other.
There is a lot of development on cooperative visualization via communication networks. User interaction is kept to minimum in this kind of development such as only making marks on the transmitted images etc.There are relatively less work done on cooperative complicated interaction especially on real time cooperative interaction via network. The work presented in this paper is a challenge to the second type of cooperative work. The objective of the system is to allow multiple users to design a 3D scene cooperatively via communication networks in real time.The paper describes the design and communication model of the system, the design and implementation of the protocol to transmit changes in the 3D-scene, the database consistency techniques and the implementation of the 3D-editor interface. The current implementation status of the system shows that a real time, full user interaction in 3D cooperative design via communication networks is achievable by our design strategy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
