This paper discusses network-wide energy optimization of embedded systems which can adapt by switching configurations. We model applications and their task chains in a network of embedded devices, including sleep modes and change of configuration, which provides a basic adaptation mechanism. We present a formal model of the energy consumption for such(More)
One goal of research activities is finding ways to manage the growing complexity of embedded systems using self-configuration methods. While autonomous configuration could potentially be used in safety-critical and real-time systems, the basic requirements are not yet in place. This paper will outline a concept for the real autonomous configuration of(More)
This paper presents and evaluates a new approach of energy estimation for single software components based on program flowcharts. This estimation is designed to be applicable early in the design process, which enables system designer to evaluate different design variants with respect to the energy consumption of the later system. The energy estimation model(More)
—This paper discusses the next steps towards how system developers can easily and accurately evaluate the impact of their system design choices on energy consumption during the early stages of the design process. To do this, energy estimations in every phase of system development are necessary. Our research focuses on adaptive systems, where applications(More)
With the advent of modernity, the nexus between language and society changed in quite dramatic ways. Within the nation-state, monolingualism came to be seen as the ideal for fostering unity and for ensuring successful communication between all nationals, while foreign language learning was encouraged in order to establish and maintain contact with other(More)
