In this paper, a necessary and sufficient condition for the controllability of networked systems with heterogeneous dynamics is established where nodes are higher dimensional linear time invariant network topology directed weighted. The system over some specific topologies also examined non-controllability results obtained. theoretical demonstrated examples.

Considerable research has focused on securing SCADA systems and protocols, but an efficient approach for conducting experiments that measure the impact of attacks on the cyber and physical components of the critical infrastructure is not yet available. This paper attempts to address the issue by presenting an innovative experimental framework that incorporates cyber and physical systems. An emu...

Rapid advances in consumer electronics have led to the anomaly that consumer off-the-shelf gaming hardware and software provide better interactive graphics than military and other specialized systems costing orders of magnitude more. UTSAF (Unreal Tournament Semi-Automated Force) is bridging software written to take advantage of the power of gaming systems by allowing them to participate in dis...

The past few years have shown a need for fundamentally new approaches to the security and survivability of large scale networked systems. Infrastructures and other modern systems pose problems that arise from many factors: partial information, complexity of combined interactions of very large numbers of human and automated participants, ubiquitous access, loss of centralized administrative cont...

We model networked storage systems with distributed, cryptographically enforced file-access control in an applied pi calculus. The calculus contains cryptographic primitives and supports file-system constructs, including access revocation. We establish that the networked storage systems implement simpler, centralized storage specifications with local access-control checks. More specifically, we...

Grid Computing is a mechanism of distributed computing to coordinate and share the networked resources, data domains, storage devices and processing power across geographically distributed locations. In the computational grid network, information services are basically providing information of infrastructure resources. The Information includes configuration of resources, policies, agreements ar...

The communication infrastructure among various interconnected devices has revolutionized the process of collecting and sharing information. This evolutionary paradigm of collecting, storing and analyzing data streams is called the Internet of Everything (IoE). The information exchange through IoE is fast and accurate but leaves security issues. The emergence of IoE has seen a drift from a singl...

Centralized water infrastructure has, over the last century, brought safe and reliable drinking to much of world. But climate change, combined with aging underfunded infrastructure, is increasingly testing limits of—and reversing gains made by—this approach. To address these growing strains gaps, we must assess advance alternatives centralized provision sanitation. The literature rife examples ...

In this paper, we introduce a middleware infrastructure that provides software services for developing and deploying highperformance parallel programming models and distributed applications on clusters and networked heterogeneous systems. This middleware infrastructure utilizes distributed agents residing on the participating machines and communicating with one another to perform the required f...
