Model quality is one of the decisive factors that affect the performance of model-based controllers. However, the existing methods were devoted to the monitoring of the overall model quality, and didn't distinguish mismatch of the process model and the disturbance model. Aiming at this problem, this paper presents a new method for monitoring the quality of process model based on input and output data...
Remote electrocardiograph (ECG) monitoring systems are gaining increasing attention with the progress of time. However, the traditional heart rate calculation formula has numerous limitations. This study presents a simple and rapid algorithm for heart rate calculation. This algorithm can provide an approximate heart rate even when the ECG signal contains noise. When this formula is used in an ECG...
In this paper, we introduce memos, which integrates suitable memory management policies and schedules resources over the entire memory hierarchy in hybrid memory system. Powered by an OS kernel level monitoring tool, memos captures memory patterns online, and then leverages them to guide the memory page placement and data mapping. Experimental results show, on average, memos can benefit memory utilization,...
An online monitoring method of machining error of the long and thin cylinder during boring process is introduced. Machining errors usually appear as the offset of spatial location of actual cutting path compared to ideal cutting path. In order to monitor machining error of workpiece, the tool actual cutting path on workpiece in boring process was studied. The multi-body system theory and processing...
A radio monitor station (RMS) collects the radio signal information of a large range of frequency for the management of radio bandwidth usage. To meet the challenges of large dynamic data, we have developed a domain specific management information system (MIS) for the radio monitor stations. The system design and implementation are described in the paper. An algorithm is provided to work with the...
With its unique and exceptional nature, photonic optical fiber (PCF), widely used in optical fiber sensors, is welcomed to structural health monitoring. However, few research on PCF subjected to transverse stress is reported. In this paper, by using the finite element analysis software -ANSYS, several kinds of photonic crystal fibers of different structural parameters were analyzed. The changing relation...
Intranet security management system is mainly in charge of the unified security management of host computer. The paper finds the objectives and functional requirements of intranet security by analysis. Through the analysis, treatment and control of intranet security, a fairly complete solution of intranet security is put forward.
Pervasive computing is providing its usability and scope in almost every aspect nowadays. In order to make better use of pervasive services in nomadic devices, pervasive client download might be needed, which would result in serious security problems due to executing untrusted applications. Recently Security-by-Contract has been proposed to address this problem, where an application is required to...
