For enjoying 3D video to its full extent, access and consumption of 3D content should be user centric, which in turn ensures enhanced quality of user experience. The experience nevertheless is easily influenced by several factors, including content characteristics, users’ preferences, contexts prevailing in various usage environments, etc. Utilizing ambient illumination as an environmental cont...

social tagging, as a novel approach to information organization and discovery, has been widely adopted in many Web2.0 applications. The tags provide a new type of information that can be exploited by recommender systems. Nevertheless, the sparsity of ternary interaction data limits the performance of tag-based collaborative filtering. This paper proposes a random-walk-based al...

onion is one of the important strategic crop plants of a highly valuable nutritional food source, consumed almost around the whole world. thus, the genetically oriented studies around the plant are valuable and inevitable. for a following of these studies, some onion masses from various regions throughout iran, including: kashan-white, azarshahr-red, isfahan-dorcheh, ghom-white, zanjan-gholighe...

End-users information capture remains a sensitive challenge, especially when information is under the form of documents. The difficulty concerns information indexing so that information can be precisely queried. In the DRUID project, the end-user captures XML paragraph-centric documents (i.e. documents with tags delimiting narrative text paragraphs), and a transformation tool generates XML data...

Conventional introduction to computer science presents individual algorithmic paradigms in the context of specific, prototypical problems. To complement this algorithm-centric instruction, this paper additionally advocates problem-centric instruction. I present an original problem drawn from student life that is simply stated but provides for rich discussions of different approaches. It lends i...

The development of shorthand handwriting recognition for pen-centric interfaces can provide the critical infrastructure for natural pen-centric interactions to enhance many pen-centric learning applications. The technical innovations include chatroom and special-symbol shorthand as well as appropriate online handwriting recognition strategies for small form-factor devices. Famous writers throug...

a student-centric research education program with the active participation of undergraduate students is initiated. the aim is to imbibe ―responsible citizenship behavior‖ in them so that each member becomes conscious and well trained to take up environmental-related issues and challenges for long-term sustainability of the ecosystem. in this work, we report spectrophotometer-based estimation of...

177 Abstract—Considerations for user-centric environments are regarded as essential for the successful deployment of convergence services in BcN. Event driven service (EDS) is regarded as a typical convergence service converging different functions of multiple service providers to support user-centric environments. This paper first describes the deployment model and service scenario of EDS, a c...
