Abstract:

Embedded systems are playing an increasingly important role in control engineering. Despite their popularity, embedded systems are generally subject to resource constraints and it is therefore difficult to build complex control systems on embedded platforms. Traditionally, the design and implementation of control systems are often separated, which causes the development of embedded control systems to be highly timeconsuming and costly. To address these p ....etc

Abstract
Sustainable operation of battery powered wireless embedded systems (such as sensor nodes) is a key challenge, and considerable research effort has been devoted to energy optimization of such systems. Environmental energy harvesting, in particular solar based, has emerged as a viable technique to supplement battery supplies. However, designing an efficient solar harvesting system to realize the potential benefits of energy harvesting requires an in-depth understanding of several factors. For example, solar energy supply is high ....etc

The Embedded Systems Design Challenge



1 Motivation
Computer Science is going through a maturing period. There is a perception
that many of the original, defining problems of Computer Science either have
been solved, or require an unforeseeable breakthrough (such as the P versus NP
question). It is a reflection of this view that many of the currently advocated
challenges for Computer Science research push existing technology to the limits
(e.g., the sem ....etc
