Service-centric systems are driven more and more towards self-adaptation in order to satisfy QoS in highly dynamic environments. However, the young age and immaturity of this domain, combined with the increasing size and complexity of these systems, hinder the architects from designing effectively self-adaptive systems. This paper addresses the main problems that architects face with respect to...

[Context and motivation] Non-functional requirements (NFRs) play a fundamental role when software architects need to make informed decisions. Criteria like efficiency or integrity determine up to a great extent the final form that the logical, development and deployment architectural views take. [Question/problem] Continuous evidence is needed about the current industrial practices of software ...

System architects are scarce. If we want to search or educate potential system architects, then it is useful to know factors that determine the success of system architects. In this presentation we look at 4 areas: nature, education, environment and experience. We will make these areas more specific by quantification and illustration. Distribution This article or presentation is written as part...

For many years the software architecting process has been understood as the engineering of a software architecture solution. This is typically documented in a number of views, which illustrate the aspects judged relevant for a number of addressed stakeholders. This perspective can be defined as “architecture as a product”. In this paper we focus on the shift from “architecture as a product” tow...

Enterprise Architecture (EA) is increasingly being used by large organizations to get a grip on the complexity and inflexibility of their business processes, information systems and technical infrastructure. Although seen as an important instrument to help solve major organizational problems, effectively applying EA seems no easy task. Efficient collaboration between architects and EA stakehold...

In face-to-face conversation, the arrangement of bodies and the shared physical environment provides a rich set of resources for communication. People use the location and orientation of their gaze, heads, hands, and torsos, to help to define, amongst other things, when a conversation begins and ends, their levels of mutualengagement, their participant roles in the conversation (e.g. speaker, h...

Dps proteins are the structural relatives of bacterioferritins and ferritins ubiquitously present in the bacterial and archaeal kingdoms. The ball-shaped enzymes play important roles in the detoxification of ROS (reactive oxygen species), in iron scavenging to prevent Fenton reactions and in the mechanical protection of DNA. Detoxification of ROS and iron chaperoning represent the most archetyp...

2 of 41 Real-time Signal Processing on the Ultrasparc 1.0 Abstract With the convergence of audio, video, and the Internet, multimedia applications increasingly demand real-time processing from general purpose CPUs. Traditionally, computer architects have increased the performance of CPUs in incremental steps, increasing the number of cache levels, increasing the complexity of I/O controllers, i...

A b s t r a c t In this paper, we briefly discuss the dynamic and functional approach to computer symbolic tensor analysis. The ccgrg package for Wolfram Language/Mathematica is used to illustrate this approach. Some examples of applications are attached.
