With the increased requirements of environmental protection, the problem of industrial boiler NOx emissions become more and more notable. The practical coal and the same air-distribution method as the one in the actual stoker boiler were applied to study the NOx formation characteristics in a unit-boiler with the purpose of studying the NOx formation characteristics in the chain-boiler. Measuring...
Monitoring virtual machine (VM) is an essential function for virtualized platforms. Existing solutions are either coarse-grained - monitoring in granularity of VM level, or not general - only support specific monitoring functions for particular guest operating system (OS). Thus they do not satisfy the monitoring requirement in large-scale server cluster such as data center and public cloud platform,...
Summary form only given: Networked sensors and actuators are increasingly pervasive in our daily lives, from tracking inventory in warehouses to monitoring movement of environmental pollutants and helping elderly living a more independent life. The data collected by the sensors needs to be distilled into higher level information and knowledge that must be promptly acted upon by autonomous controllers...
With the development of virtualization technology, file protection in virtual machine, especially in guest OS, becomes more and more important. Traditional host-based file protection system resides the critical modules in monitored system, which is easily explored and destroyed by malwares. Moreover, in order to protect the multiple operation systems running on the same platform, it is necessary to...
A sensor network data gathering and visualization infrastructure is demonstrated, comprising of global sensor networks (GSN) middleware and Microsoft SensorMap. Users are invited to actively participate in the process of monitoring real-world deployments and can inspect measured data in the form of contour plots overlayed onto a high resolution map and a digital topographic model. Users can go back...
In recent years, virtualization technology has been widely applied to traditional computing environment. As it provides strong flexibility, the security in face of attacks to network services becomes a significant challenge. In this paper, we propose a novel architecture to detect intrusion in virtual computing environment and implement a prototype, named VNIDS. In this system, a particular VM is...
This paper proposes a realistic data grid system named JobGrid to construct information platform for Chinese college graduates employment, which supports centralized transaction processing to ensure consistent, effective operation in data access, control, monitor and analysis, and distributed data management to provide heterogeneous data integration, conversion, exaction and export. JobGrid has implemented...
