When two or more subsystems of a quantum system interact with each other they can become entangled. In this case the individual subsystems can no longer be described as pure quantum states. For systems with only 2 subsystems this entanglement can be described using the Schmidt decomposition. This selects a preferred orthonormal basis for expressing the wavefunction and gives a measure of the de...

We consider quadratic stabilizability and H∞ disturbance attenuation of switched systems which are composed of a finite set of linear time-invariant subsystems. The situation is that none of the subsystems is quadratically stable with certain H∞ disturbance attenuation level but a convex combination of the subsystems achieves such performance. We then design a state-dependent switching signal (...

The approach to a substantiation of thermodynamics is offered. A conservative system of interacting elements, which is not in equilibrium, is used as a model. This system is then split into small subsystems that are accepted as being in equilibrium. Based on the D’Alambert equation for a subsystem the generalized Liouville equation is obtained. A necessary condition for irreversibility is deter...

Thinking in terms of SoS brings a 180 change in viewpoint. In traditional embedded systems design (being a subsystem in itself) we focus on how to effectively design those embedded subsystems to implement the functions of a device.This device plays a role in the physical world. With the introduction of embedded networking we move to cyber-physical systems in which these embedded subsystems now ...

The integration of multiple automotive subsystems (e.g., powertrain, safety, comfort) on a single distributed computer system can significantly reduce the number of Electronic Control Units (ECUs) and networks for in-vehicle electronic systems. The benefits of this integration include reduced hardware cost and reliability improvements due to fewer connectors. However, a major challenge in such ...
