System chip, system on chip (SOC), system on silicon (SOS), there are many terms and many definitions that have arisen to describe the large chips that are emerging as we move further into the murky depths of the deep submicron era. Almost everyone has their own definition of system chip, which may explain why it is that almost everyone can claim to be designing system chips. However, as they b...

A method is proposed for evaluating a range of System of Systems (SoS) meta-architecture alternatives. SoS are composed through combination of existing, fully functioning Systems, possibly with minor functional changes, but certainly by using the combined Systems to achieve a new capability, not available from the Systems alone. The meta-architecture describes how all possible subsets of System...

Systems of systems comprise entities that are complex enough to be considered as systems in their own right. The interactions within a system of systems (SoS), unlike monolithic systems, are not constrained by physical design. The dynamic nature of SoS means that complex interactions are allowed to occur between the entities of a SoS. These interactions can lead to accidents. The road, rail and...

Recent engineering experiences highlight the Ballistic Missile Defense System (BMDS) as a System of Systems (SoS), and traditional probability models were limited in capturing the complex interactions between component systems. A novel approach was proposed to evaluate the effectiveness of the whole BMDS from the aspect of functional interactions, rather than the functions of components. First,...

Symbolic data analysis aims at generalizing some standard statistical data mining methods, such as those developed for classification tasks, to the case of symbolic objects (SOs). These objects synthesize information concerning a group of individuals of a population, eventually stored in a relational database, and ensure confidentiality of original data. Classifying SOs is an important task in ...

This paper describes the use of sums-of-square (SOS) program to compute a resilience measure for nonnegative dynamical systems. Such measure is defined as the distance between system’s nominal parameter and the closest critical paramater at which a bifurcation occur. Our proposed method uses a modeling formalism from chemical reaction network theory to describe the dynamics of nonnegative syste...

Our world is a complex socio-technical system-of-systems (Chappin &Dijkema, 2007; Nikolic, 2009). Embedded within the geological, chemical and biological planetary context, the physical infrastructures, such as power grids or transport networks span the globe with energy and material flows. Social networks in the form of global commerce and the Internet blanket the planet in information flows. ...

In this paper, we study a single server Markovian queue with state dependent accessible services, reneging and feedback of customers. The server can accommodate at the most $d$ customers in the service station, after which the new arrivals have to wait in the primary queue of infinite waiting space. All arrivals demand First Essential Service (FES), after completing FES, customers decide to joi...
