Model-Based Design of Defense Cyber-Physical Systems to Analyze Mission Effectiveness and Network Performance

open access: yesIEEE Access, 2019
This paper discusses two modeling and simulation (M&S) issues for defense cyber-physical systems (CPSs): 1) model-driven development via model interoperation and 2) simulation analysis between interoperated models.

Robust dual reconstruction systems and fusion frames [PDF]

open access: yes, 2011
We study the duality of reconstruction systems, which are g-frames in a finite dimensional setting. These systems allow redundant linear encoding-decoding schemes implemented by the so-called dual reconstruction systems. We are particularly interested in

Application of systems engineering to complex systems and system of systems

open access: yes, 2017
This dissertation is an investigation of system of systems (SoS). It begins with an analysis to define, with some rigor, the similarities and differences between complex systems and SoS. With this foundation, the baseline concept is development for several different types of systems and they are used as a practical approach to compare and contrast ...

Hypernetworks for Policy Design in Systems of Systems of Systems [PDF]

open access: yes, 2013
Hypernetworks generalise networks and hypergraphs, allowing relations between many things to be modelled by hypersimplices with richer structure than hypergraph edges. They provide a way of integrating bottom-up and top-down micro, meso and macrolevel dynamics in multilevel systems. They provide a natural way of representing social structures, enabling

Proving Skipping Refinement with ACL2s

open access: yes, 2015
We describe three case studies illustrating the use of ACL2s to prove the correctness of optimized reactive systems using skipping refinement. Reasoning about reactive systems using refinement involves defining an abstract, high-level specification ...
