The microstructure, mechanical properties (at 25 °C, 1000 1200 1400 °C and 1600 °C) oxidation behavior of a binary Hf-27%Ta alloy three ternary alloys, Hf-21%Mo-21%Ta, Hf-21%Nb-21%Ta Hf-21%Ta-21%W (compositions are in atomic percent) reported. alloys were produced by vacuum arc melting, hot isostatically pressed under high-purity argon pressure 207 MPa at for 3 h slow cooled to room temperature...

— This paper presents the progress and final state of CAIN-21, an extensible and metadata driven multimedia adaptation in the MPEG-21 framework. CAIN-21 facilitates the integration of pluggable multimedia adaptation tools, automatically chooses the chain of adaptations to perform and manages its execution. To drive the adaptation, it uses the description tools and implied ontology established b...

In this paper, we present our work on two aspects of multimedia adaptation: knowledge-based single media adaptation and semantic adaptation of multimedia documents. For the former, we propose support of adaptation by direct hinting in the scope of MPEG-21. For the latter, which is the main part of the presented work, we introduce the description of semantic dependencies between media objects of...

Within an MPEG-21 architecture, the two key concepts are the Digital Item, representing multimedia content, and Users, interacting with this content. MPEG-21 introduced Digital Item Processing to allow content authors to describe suggested processing of their Digital Items. It standardizes ways to insert functionality into a Digital Item, as such, creating a dynamic and interactive multimedia f...

With the advent of restructuring in power industry, conventional unit commitment problem systems, involving minimization operation costs a traditional vertically integrated system structure, has been transformed to profit-based (PBUC) approach, whereby generation companies (GENCOs) perform scheduling available production units with aim profit maximization. Generally, GENCO solves PBUC for parti...
