Tumor hypoxia has been shown to decrease the sensitivity of solid tumors to radiation. Systemic efforts to increase tumor oxygenation levels immediately prior to therapy, however, have largely proven unsuccessful. The objective of this work was to determine the utility of oxygen-filled, ultrasound sensitive microbubbles for locally delivering oxygen and sensitizing tissue to radiation in a breast...
As a column-oriented, distributed and high fault-tolerant database, HBase is gradually adopted by manufactory industry due to its huge capacity, fast random read and bulk processing performance. Power grid usually generates huge amount of data from multi-sources with hundreds of complicated data types. However, JOIN operation performance is low in HBase since it was not designed to serve relational...
Due to the lossy nature of wireless links, it is difficult to determine if packet losses are due to wireless-induced effects or from malicious discarding. Many prior efforts on detecting malicious packet drops rely on evidence collected via passive monitoring by neighbor nodes. However, they do not analyze the cause of packet losses. In this paper, we ask: 1) Given certain macroscopic parameters of...
IBIS-L ground based SAR is able to provide accurate and long-term measurements over relative large areas by combining of stepped frequency continuous wave, synthetic aperture radar and interferometric technique. To measure displacements of an open pit slope in Beizhan iron mine, a novel environmental correction method is presented to perform the atmospheric distortion correction of GB-InSAR. GB-InSAR...
In this paper, 42 X-band COSMO-Skymed (CSK) images are processed using Permanent Scatterer InSAR (PSI) technique in order to monitor and analyze deformation phenomena in Beijing urban areas between January 2009 and August 2011. Italian COSMO constellation composed of four satellites is capable of acquiring SAR data with 8 day repeat cycle with up to 1 meter resolution. The results show significant...
Tremendous underground exploitation as subway tunneling, functional facilities excavation in inner-city environments caused potential damages to buildings and bridges over the construction zone. PSInSAR technique and high resolution SAR data provides a powerful tool for slightly surface deformation in recent years. Till now, it is time to use PSInSAR as an operational and mature technique for geodesy...
Using RADARSAT-2 satellite images from January 2012 to October 2015, this paper employ the PSInSAR(Permanent Scatterer InSAR) technique to acquire coastal lowland subsidence in Zhejiang province. In the Hangzhou Bay Region, the widely distributed silt deposition leads to the entire ground sinking slowly, with 10∼20mm/a in rate. Conversely, the ground subsidence distribution of the Eastern Coastal...
As accidents frequently occurred in aerospace applications, traditional reliability analysis methods are not enough for modern flight control software. To find a comprehensive, effective and intelligent method for software fault diagnosis is urgent for airborne software engineering. Consequently, in this paper, a novel knowledge-based diagnosis system is constructed for flight control software, by...
A singularly perturbed reaction-diffusion problem with mix boundary conditions is solved numerically by using an adaptive grid method. The mesh is constructed adaptively by a grid generation algorithm. A linear and a semi-linear examples are tested. It is shown from the numerical results that the presented method is very efficient.
NDN enables routers to cache received contents for future requests to reduce upstream traffic. To this end, various caching policies are proposed, typically based on some notion of content popularity, e.g., LFU. But these policies simply assume the availability of content popularity information without elaborating how that information is obtained and maintained in routers. Towards line-speed and accurate...
Modern telecommunications enterprises have many Application system In order to integrate several heterogeneous system effectively and guarantee the data consistency, enterprise Application Integration is always structured by RMI, CORBA, Web Services, to provide the messaging service. If the ODS is acted as the share data source of telecom enterprise application integration system, and the message...
Base on the analysis of traditional long-range medical healthcare system, the human body healthcare system used in the family is introduced in this paper. According to the requirements of family health monitor system, the paper compares several kinds of wireless communication technology which uses in the family, The system is presented to combine the short-range wireless communication technology Zigbee...
L'Aquila area has a high topography and complex geological structures, and is covered with thick vegetation and snow in areas of high topography. To monitor the characteristics of crustal deformation in this region before the 2009 L'Aquila earthquake, we apply StaMPS software to analyse 20 descending ASAR images acquired between September 2003 and March 2007 and 39 ascending ASAR images acquired between...
Insect pests and diseases are major constraints to crop yield. Solutions to pests and diseases management are inevitably not independent of location. In the current study, a web-base geographic information system for crop pests and diseases management system was developed using ArcIMS, ASP.NET, networking and database management technologies. The application system provides client users with pests...
The publicly available BGP vantage points (VPs) have been heavily used by the research community to build the Internet autonomous system (AS) level topology, which is a key input to many applications, such as routing protocol design, performance evaluation and network security issues. However, a detailed study on the eyeshots of these VPs has received little attention before. In this paper, we inspect...
Amino-Desulphurization technology has been widely used to reduce the pollutant emission in coal-fired power plants. However, excessive amino sprayed, not only results in the waste of liquid amino, but also brings a great error of the concentration retrieval of SO2 by Continuous Emission Monitoring System(CEMS) based on Differential Optical Absorption Spectroscopy(DOAS). To find an effective retrieving...
This paper presents a smart ZigBee indoor security system based on the small-scale fading effect of RF signals. The received signal strength in a wireless network stays stable with low variances in a closed indoor environment. The movement of objects will induce a small-scale fading effect, resulting in dramatic changes of the signal strength. The main idea is to deploy a ZigBee network in the detection...
We propose to use the SYN/ACK-CliACK pair's behavior to detect the various SYN flood attacks more accurately. The SYN/ACK packets carry the full information of the TCP connections and it is impossible for the attacker to evade the detection by spoofing the control packets. Moreover, we use a space efficient data structure, counting Bloom filter, to recognize the CliACK packet and the memory cost is...
A multi-server video monitor system based on streaming media communication technology is proposed. Large-scale, long-distance monitoring requirements have been met. The video monitor software is researched, which has the function of video restoration, proprietary protocol is used to realize video transmitting smoothly. In the part of the software programming, multi-threaded mechanism and double buffering...
For solving measurement problem of spanless points of complex rotary mechanical drive system, a new torsional vibration measuring model of spanless points was proposed by using continuous shaft segment model. The measuring model could calculate torsional vibration parameter values of spanless points utilizing testing data of measurable points. The correctness of theory was verified by torque testing...
