The emergence of many heterogeneous sensor systems on the Web has produced huge amounts of sensor data. This requires building the customized and automated processing methods, which can be formed by connecting the services on the Web. Based on the semantic Web services markup language named OWL-S, the algorithms for processing sensor data on the Web are represented as the service ontologies and become...
Cloud platforms and services usually provide an APIlayer as decoupled, language agnostic interface for both front-endclient integration and back-end data and/or function access. Theavailability and performance of the APIs have significant impact onthe quality of end user or client experiences due to its nature ofinteraction endpoints. However, the extreme dynamics, complexityand scale of the current...
A new generation of home healthcare monitoring system strives to have such characteristics as low-cost, low-power and low-volume etc., and furthermore, it needs to quickly adapt to the development of national medical information based Cloud computing in China. In response to this trend, a Cloud-assisted home health monitoring system was designed in this paper. Sensors can be selectively configured...
Xen is a powerful virtualization solution which enables multiple virtual machines to run in a single physical machine isolatedly. Since the hardware resources of a physical machine (e.g., the CPU) are limited and they have to be shared by multiple virtual machines, the performance of virtual machines might be degraded. How to allocate the underlying hardware resources to virtual machines appropriately...
There is advantage of fixed physical location for airfield lighting in airport lamp monitoring using WSN, but some lamps location is irregular, which caused large consumption of the cluster head nodes in this logic region, early death, the formation of voids during transmission, and these voids undermined the entire wireless sensor networks energy balance, reduced the WSN lifetime. To solve these...
Advanced Persistent Threat (APT) poses a serious threat to cyber security, and its unique high unpredictability, deep concealment and grave harmfulness make the traditional network monitoring technology facing unprecedented challenges in the background of massive and complicated network traffic. This paper aimed for the urgent demand of APT network monitoring. Relying on the rapid development of big...
The skyline query processing over uncertain data streams has received considerable attention, due to its importance in helping users make intelligent decisions over complex data. Nevertheless, existing studies only focus on retrieving the skylines over data streams in a centralized environment typically with one processor, which limits the scalability of algorithms and cannot meet the requirement...
Due to the rapid development of the modern world, the stress is rapid increasing to the human being. For the patients of panic disorder who suffer from hyperventilation syndrome. This study proposes a portable system to monitor the oxygen concentration in the blood, and then provides proper advices for releasing. This system would make the patients feel better when they are in the shadow of panic...
The airfield lighting system is very important for airplanes to land and take off safely. It is especially important for night flights. However the environments for the airfield lighting are usually rough and wide, posing great difficulties to inspection and maintaining. For these reasons a airfield lighting monitoring system is urgently required. It could detect the failure position quickly and accurately...
A large number of overhead power lines are transferred to underground due to city beautification recently in China. Leakage gas from the pipeline usually spreads to the cable duct. It becomes a risk issue to cable operation safety and higher demand for safe protection of the cable duct is needed. The paper describes the online auto-monitoring system of city underground cable duct, that is the design...
