New embedded systems are being built with new types of energy sources, including solar panels and energy scavenging devices, in order to maximize their utility when battery and A/C power are unavailable. The large dynamic range of these unsteady energy sources is giving rise to a new class of power-aware systems. They are similar to low-power systems when energy is scarce; but when energy is ab...

The current situation in the eld of computer aided dynamic systems modeling is syrveyed, and the contemporary tools for computer aided modeling are discussed. It is proposed that there is a need also for special purpose modeling tools that are able to manipulate the models without destructing their structure. The role of symbolic calculation in combination with object-oriented modeling is empha...
