Detecting runtime anomalies is very important to monitoring and maintenance of distributed services. People often use execution logs for troubleshooting and problem diagnosis manually, which is time consuming and error-prone. In this paper, we propose an approach for automatic anomaly detection based on logs. We first mine a hybrid graph model that captures normal execution flows inter and intra services,...
Detecting execution anomalies is very important to monitoring and maintenance of cloud systems. People often use execution logs for troubleshooting and problem diagnosis, which is time consuming and error-prone. There is great demand for automatic anomaly detection based on logs. In this paper, we mine a time-weighted control flow graph (TCFG) that captures healthy execution flows of each component...
Shared last-level cache (LLC) management is a critical design issue for heterogeneous multi-cores. In this paper, we observe two major challenges: the contribution of LLC latency to overall performance varies among applications/cores and also across time; overlooking the off-chip latency factor often leads to adverse effects on overall performance. Hence, we propose a Latency Sensitivity-based Cache...
This paper simply introduces the meaning and equipment of radio monitoring, and mainly discusses how to design a platform which can storage, manage, retrieve and analysis radio coverage data based on B/S model by using database and Baidu map JavaScript API technology and combining with the characteristics of radio monitoring equipment. Radio coverage data from radio monitoring equipment will go into...
With more and more applications of Internet of things (IoT) technologies, the quality of life of residents is one of the most important aspects in smart cities. Specially, home healthcare monitoring for the disabled and / or the elderly has become a focus of recent researches and developments. Existing home healthcare systems have drawbacks such as simple and few functionalities, weak interaction...
The Fish4Knowledge (F4K) project involves analysing video generated from multiple camera feeds to support environmental and ecological assessment. A workflow engine is utilised in the project which deals with on-demand user queries and batch queries, selection of a suitable computing platform on which to enact the workflow along with a selection of suitable software modules to use to support analysis...
Aiming at characteristics of operation training in distributed simulation training system, an operations monitoring platform was proposed and established in the simulation training system Based on HLA (High Level Architecture). In this platform, the services provided by RTI (Run-Time Infrastructure) are used to receive and dispatch federation data. Determine the reasonableness of the operating logic...
Managing complex enterprise networks requires an understanding at a fine granularity than traditional network monitoring. The ability to correlate and visualize the dynamics and inter-relationships among various network components such as hosts, users, and applications is non-trivial. Network security visualization is a highlighted topic of network security research in recent years, The existing research...
Information and communication technologies have been used to provide valuable services in our daily lives in the form of consultation and recommendation. However, the key factor of a successful service model is the integration of domain knowledge. To show a feasible fusion model as an example, we propose the system design of an intelligent consultation and recommendation framework to assist nutritionists...
Due to the establishment of Poyang Lake National Nature Reserve, we pay more attention to water pollution, so it is important to improve early warning mechanisms. My article will analysis the main source of Poyang Lake water quality parameters, establish gray GM(1,1)model, through the river into the lake water quality data to predict the water quality of Poyang lake area .Inspect after get results...
A novel wearable physiological monitoring system is presented in this paper. The related signal and noise characteristics obtained by the system under electromagnetic and body motion interferences are analyzed and the performance of the active electrode circuit is assessed. It is concluded that the active electrode can eliminate the noise caused by electromagnetic interference significantly, but has...
With Shenfudongsheng Mining as the study area, calculating the net primary productivity of vegetation based on HJ data, combined with the landscape indices, the author constructed the macro-structure model of mining ecosystem, and dynamically evaluated the mining ecological structure. The results showed that: Shenfudongsheng mining vegetation productivity is very poor, by calculating the average NPP...
With booming of the technology of wireless sensor network and the technology of GSM/GPRS, this paper proposed an engineering solution of remote water quality monitor solution. The solution has been implemented and applied in monitoring the water quality of Poyang lake. Based on the mass of monitoring data, this paper proposed a model, which can be used in pridication of the quality variation of Poyang...
Memory Wall is a well-known obstacle to processor performance improvement. The popularity of multi-core architecture will further exaggerate the problem since the memory resource is shared by all cores. Interferences among requests from different cores may prolong the latency of memory accesses thereby degrading the system performance. To tackle the problem, this paper proposes to decouple application...
Although medical technologies developed in the twenty-first century have successfully increased man's life span, the pressure of modern life has consequently brought many modern civilization diseases and chronic illness. When all these problems are tackled by hospitals, they will consume considerable amount of medical resources. Alternatively, providing health care services at home is an important...
On the basis of shortage existing in traditional WebGIS, this paper puts forward a novel WebGIS framework based on Ajax, Web Services and SOA. The framework combines Ajax with Web Services. Through invocating Web services asynchronously by Ajax, the problems of poor user experience, system isomeric compatibility, system integration and mutual operation etc. are solved. The conclusion means a great...
An ECG monitoring system comprised of six wearable textile-based electrodes is used to detect the ECG and sitting posture of vehicle drivers. The electrodes are washable, comfortable, sewed into ordinary shirt, and not connected with extra wires; as a result, they not only detect drivers' ECG while they move, but also prevent hindering their driving. While drivers change the sitting postures, different...
