Knowledge representation and engineering techniques are becoming useful and popular components of hybrid integrated systems used to solve complicated practical problems in different disciplines. These techniques offer features such as: learning from experience, handling noisy and incomplete data, helping with decision making, and predicting capabilities. In this paper, we present a multi-domain...

Digital preservation is increasingly recognized as a need by organizations from diverse areas that have to manage information over time and make use of information systems for supporting the business. Methods for assessment of digital preservation compliance inside an organization have been introduced, such as the Trustworthy Repositories Audit & Certification: Criteria and Checklist. However, ...

Research on dynamic capabilities emphasizes the importance and role of organizational routines in explaining interfirm differences in performance. While performance differences are well documented, few empirical analyses explore the processes inside organizations that lead to dynamic capabilities or attempt to define and measure their performance effects. This paper examines one type of dynamic...

A proper support for multimedia communications transport has to provide fault tolerance capabilities such as the preservation of established connections in case of failures. While multi-homing addresses this issue, the currently available solution based in massive BGP route injection presents serious scalability limitations, since it contributes to the exponential growth of the BGP table size. ...

This paper develops a framework of analysis of the emerging organisational network topology of the new knowledge-driven economy in order to identify critical success factors in the process of innovation. The central argument of the paper is that innovation constitutes the foundation of the competitiveness and value-creation capabilities of economic organisations. However, innovation is not some...

The majority of light aviation aircrafts cabins are unpressurized and this may pose risks for the safety of both pilots and passengers. As altitude increases partial oxygen pressure decreases and this situation may lead to early stages of hypoxia affecting pilot’s capabilities to perform simple tasks. These factors combined in several ways may affect significantly the capability of a pilot to c...

While level of detail (LoD) methods for the representation of 3D models are efficient and established tools to manage the trade-off between speed and quality of the rendering, LoD for animation has not yet been intensively studied by the community, and especially virtual humans animation has not been focused in the past. Animation, a major step for immersive and credible virtual environments, i...

Transcoding is an effective method to provide video adaptation for heterogeneous internetwork video access and communication environments, which require the tailoring (i.e., repurposing) of coded video properties to channel conditions, terminal capabilities, and user preferences. This paper presents a video transcoding system that is capable of applying a suite of error resilience tools on the ...
