Resumo. Com a rápida evolução dos sistemas computacionais, simulações numéricas baseadas em modelagem computacional têm alcançado soluções cada vez mais realistas. Ainda assim, o processo de simulação é complexo, exigindo grande capacidade computacional e produzindo muitos arquivos auxiliares com os resultados das simulações. Uma grande quantidade de arquivos, como os produzidos durante o proce...

Learning and knowledge building have become critical competences for people in the knowledge society era. In this paper, we propose a sociolinguistic dialogue model for understanding how learning evolves and how cognitive process is constructed in on-line discussions. The knowledge extracted from this model is used to assess participation behavior, knowledge building and performance. The ultima...

Knowledge is the foundation for growth and development. Investment in knowledge improves new method for originate knowledge society and knowledge economy. Investment in knowledge embraces expenditure on education and R&D and software. Measuring of investment in knowledge is characteristically complicated. We examine the influence of investment in knowledge in multifactor productivity growth and...

Knowledge is central to the modern economy and society. Indeed, the knowledge society has transformed the concept of knowledge and is more and more aware of the need to overcome the lack of knowledge when has to make options or address its problems and dilemmas. One`s knowledge is less based on exact facts and more on hypotheses, perceptions or indications. Even when we use new computational ar...

BACKGROUND Considerable development of MRI technology in diagnostic imaging, high cost of MRI technology and controversial issues concerning official charges (tariffs) have been the main motivations to define and implement this study. OBJECTIVES The present study aimed to calculate the unit-cost of MRI services using activity-based costing (ABC) as a modern cost accounting system and to fairl...

The Internet was not designed to be a critical part of the economy—but it has become exactly that. In fact, it has become a critical infrastructure for the overall society in developed countries. There are many questions today on how the Internet will or should develop in the future. What has been asserted throughout the industry and the research community is that the Internet must change, and ...

This memo specifies a packetization scheme for encapsulating uncompressed video into a payload format for the Real-time Transport Protocol, RTP. It supports a range of standardand high-definition video formats, including common television formats such as ITU BT.601, and standards from the Society of Motion Picture and Television Engineers (SMPTE), such as SMPTE 274M and SMPTE 296M. The format i...
