It is highly desirable to monitor microwave ablation (MWA) treatments noninvasively for substantially improving the clinical implementation of MWA procedures and progress toward full clinical uses worldwide. This paper explored the feasibility of using ultrasonic Nakagami imaging to evaluate the thermal lesion induced by microwave ablation (MWA) in porcine liver. 2-D RF data backscattered from the...
It is highly desirable to monitor microwave ablation (MWA) treatments noninvasively for substantially improving the clinical implementation of MWA procedures and progress toward full clinical uses worldwide. This in vivo study explored the feasibility of using ultrasonic Nakagami imaging to evaluate the thermal lesions in liver and kidney in a porcine model for the purpose of monitoring MWA.
In order to resolve the problem in the the maintenance of missile equipment, put forward the health management architecture of missile equipment based on the prognostic and health management theory, and introduce the technology of condition monitoring, status evaluation, fault diagnosis and life prediction. The health management of missile equipment would promote the innovation of management concept,...
This paper deals with the issue on air conditioning energy consumption and system monitoring of different data in building. Various environmental parameters inside the building are changed in real time, while the conventional air conditioning energy consumption forecasting with the load simulation software cannot adapt to these variations. Therefore, the air conditioning energy consumption forecasting...
In view of the shortcomings of traditional lightning protection measures in the initiative defense, it is necessary to research lightning warning technology, which can provide decision support for avoiding the lightning strike risks of infrastructures. This paper adopted atmospheric electric field and time-differencial calculation, combined with prediction of lightning moving trend based on Lightning...
The paper designs a monitoring system, which use leakage current combined with three harmonic current to judge the running state of the arrester, on the basis of leakage current standard waveform of the surge arrester recommended by the criterion of DL/T 987-2005. The way of current sensor interconnection is used by the system to achieve the output of leakage current and the extraction of third harmonic...
Glacier change over the Qinghai-Tibet Plateau (QTP) provides an important clue to climate change in the remote high-altitude areas, and impacts various aspects of regional environment. Observations of mountain glaciers over the QTP are yet far from sufficient. Remote sensing techniques enable mapping and monitoring glaciers over an extensive region, from different dimensions and with regular revisit...
In power electronic devices, the winding temperature of the transformer in operation needs to be monitored in real time. But the Electromagnetic Interference(EMI) problems cause the measured winding temperature fluctuates anomalously. In this paper, the 10MVA transformer in the cabinet of a transformer rectifier is studied as a specific case, the temperature measurement circuit of the transformer...
Virtual machine (VM) management in cloud data center is an important problem that remains to be effectively addressed. There has been a considerable amount of work investigating the management of physical-to-virtual resource mappings to improve the efficiencies of resource usage and power consumption in data center. However, these different management objectives are conflicting. One solution can't...
Integrated test technology is the research emphasis of improving test and support capability of complex weaponry equipment. In order to solve the Analysis Hierarchical Process (AHP) method research of decision-making information system in the integrated test technology, and then to simplify the decision-making information system structure and improve the efficiency of decision-making, the paper introduces...
Previously, abundant analysis and researches have been devoted to the marine acoustic signals of dolphins. In attempt to obtain the accurate signal segments and classify the categories of acoustic data, most researchers divide the signal and classify them manually. This paper aims to introduce a new method of automatically segmenting and identifying whistles and clicks of dolphins. By analyzing the...
In power system, data acquisition plays an increasing important role in the field of modern power quality monitoring system. However, data communication expanding range of protocols, increasing the signal type, growing the supervisory instruments has become the major problem. In this paper, we present a power data acquisition and quality monitoring framework (F-PDAQM) that is a software framework...
This paper analyzes the technical characteristics of the integrated electronic system, and pointed out that the existing problems in fault diagnosis of new armoured vehicles under the condition of informatization, and describes a method of the portable armored vehicle bus testing system design and realization. Based on database technology, software multi-threading technology, as well as DMA technology,...
In this work a hierarchical fusion framework for melding multiple classifiers has been introduced, to obtain improved performance for classification problems. The fusion framework is hybrid in nature which allows for feature and decision level fusion while also being application and data agnostic. With a set of data features and a pool of trainable classifiers as input, the fusion framework utilizes...
This paper presents a multi-modal affect recognition system that is capable of effectively estimating human affective states through analyzing and fusing a number of non-invasive external cues. The proposed system consists of a probabilistic information fusion model based on the influence diagram and a set of data analysis, feature extraction and affect recognition modules for processing heterogeneous...
With data of Chinese electronic listed companies, this paper empirically analyzes the impact of corporate governance structure, operation situation and external environments on the voluntary disclosure of companies' information. The findings suggest that the share ratio of circulation stock, percentages of independent directors, separation of chairman of the board and CEO, company size and profitability...
For highway tunnel sections grew up the special traffic environment, through to the western han dynasty highway tunnel properties investigation, analysis highway tunnel sections grew up to speed the distribution of the freeway long tunnel sections divided into four segments, on this basis, it probes into the highway tunnel with speed change grew up caused by the traffic flow variation characteristics...
Mild thermal upgrading before coal utilization was an efficient method for sulfur removal as well as the quality upgrading. Two coal samples with high sulfur content from Guizhou province were selected in this study to investigate the releasing mechanism of different forms of sulfur under different atmospheres during mild thermal upgrading. The study showed that sulfur in coal can be divided into...
