This paper studies the controllability of networked relative coupling systems (NRCSs), in which subsystems are fixed high-order linear dynamics and coupled through variables depending on their neighbors, from a structural perspective. The purpose is to explore conditions for subsystem network topologies under almost all weights interaction links, corresponding numerical NRCSs controllable, call...

Modern infrastructure systems such as roadways, utility networks, telecommunications, retail, etc. are large scale complexly networked, socio-technical systems that are contributing largely to the quality of life in modern societies. The operation and control of existing infrastructures has several challenges. Technologies and business models gathering around Internet of Things (IoT) and Machin...

In current practice military communication infrastructures are deployed as stand-alone networked information systems. Network-Enabled Capabilities (NEC) and combined military operations lead to new requirements which current communication architectures cannot deliver. This paper informs IT architects, information architects and security specialists about the separation of network and informatio...

The deployment of building automation systems (BAS) allows to increase comfort, safety and security and reduce operational cost at the same time. Today such systems typically follow a twolayered hierarchical approach. While control networks interconnect distributed sensors, actuators and controllers, a backbone provides the necessary infrastructure for management tasks hosted by configuration a...

Modern technical infrastructures and appliances provide a multitude of opportunities for simplifying and streamlining the everyday life. However, many of the systems available today – such as the typical feature-loaded audio and video components – are not always efficiently usable for the average person. But, in an environment where features abound, the easy access of these features more and mo...

This paper summarizes recent research on networked virtual computing in the NICL lab at Duke. Over the past few years, we have constructed a service-oriented substrate for networked sharing and adaptive middleware environments based on a virtual on-demand computing. The goal of the project is to develop protocols and tools that can link together virtual computing clusters at different sites, an...

In large-scale networked computing systems, component failures become norms instead of exceptions. Failure-aware resource management is crucial for enhancing system availability and achieving high performance. In this paper, we study how to efficiently utilize system resources for high-availability computing with the support of virtual machine (VM) technology. We design a reconfigurable distrib...

During the last few years, the concepts of cluster computing and heterogeneous networked systems have received increasing interest. The popularity of using Java for developing parallel and distributed applications that run on heterogeneous distributed systems has also grown rapidly. This paper is a survey of the current projects in parallel and distributed Java. These projects’ main common obje...

In the future, facilities that are probable terrorist targets may be protected by weather analysis and forecasting systems that are part of automated capabilities that warn of the approach of hazardous chemical, biological, or radiological (CBR) material in the atmosphere. Based on information provided by coupled meteorological and transport and dispersion (T&D) models and networked sensors, bu...
