تمام ترکیبات اورانیم، سمی و رادیواکتیو هستند. بودن این عنصر می‌تواند کشنده باشد. با توجه به سمیت شیمیایی رادیواکتیویته ضروری است از ورود آن طبیعت جلوگیری شود. پسماندهای خروجی مراکز صنعتی- هسته­ای نیز دارای مقادیر مختلفی اورانیم می­باشد لذا حذف پساب اهمیت ویژه­ای برخوردار است. سویی دیگر، نظر محدودیت منابع آن، بازیابی پسماندها، ارزش اقتصادی می­باشد. در پژوهش حاضر، روش سطح پاسخ (RSM) بر اساس طرح م...

— 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...

Genetic modification of whole-cell cancer vaccines to augment their efficacies has a history of over two and a half decades. Various genes and gene combinations, targeting different aspects of immune responses have been tested in pursuit of potent adjuvant effects. Here we show that co-expression of two cytokine members of the common cytokine receptor γ-chain family, IL-21 and IL-7, in whole-ce...
