In this study, we propose a novel non-contact vision sensing method for wide-area monitoring of the operation conveyors in ironworks by using panoramic vibration camera real time. This can capture magnified images, including vibrations from single with mirror-driven viewpoint switching. The rotation multiple rollers conveyor belts was detected function full-pixel spectrum imaging, which calcula...

In any wide-area distributed system there is a need to communicate and interact with a range of networked devices and services ranging from computer-based ones, to network components, and specialised data sources. This paper describes, GridRM, a standardsbased framework for gathering data and information from resources distributed across the Grid that is independent of any given middleware and ...

A challenge in supporting Wide Area Applications (WAA) is that of scalable performance management. Individual Latency Profiles (iLPs) were proposed in the literature to capture latency distributions experienced by clients when connecting to a server; it is a passive measurement made by client applications and is gathered on a continuous basis. In this paper, we propose a scalable technique for ...

Multicast is proposed as a preferred communication mechanism for many power grid applications. One of the biggest challenges for multicast in smart grid is ensuring source authentication without violating the stringent time requirement. The research community and standardization bodies have proposed several authentication mechanisms for smart grid multicast applications. In this paper, we evalu...

Recent technological advances have enabled the deployment of wide area applications against Internet accessible sources. A performance challenge to applications in such a setting is the unpredictable end-to-end latency of accessing these sources. We use passive information gathering mechanisms to learn end-to-end latency distributions and construct Latency Profiles (LPs). We hypothesize that a ...

Network performance monitoring is an active area in networking research. An open problem of network monitoring research is where to put the monitoring host. A possible way is to cluster the hosts that need to be monitored based on their performance perception, and then put the monitoring node at the representative host of each cluster. In this class project, I experiment three different cluster...

The smart-power-grid brings opportunity and challenges to the power system protection and control. In previous century, there has nothing variation in the fundamental structure of the electrical power grid and vehicle networks. Rapid progress in communication and measurement techniques sharpens progress of Wide area Protection depend on the wide area measurement system. Smart-power-grid is cons...

RF MIMO Systems for Wide-Area Indoor Human Motion Monitoring by Chi Xu Department of Electrical and Computer Engineering Duke University Date: Approved: Jeffrey Krolik, Supervisor

Recently, there has been increasing interest in systems (e.g., Content Delivery Networks, Distributed Hash Tables, distributed file systems) running in large, wide-area distributed environments (e.g., Akamai, PlanetLab, RON). A key challenge to making these systems robust is the presence of correlated failures. In the context of a customizable wide-area monitoring service we developed, this pap...
