The article designs location tracking system used in underground mine based on WiFi (Wireless Fidelity) technology. The WiFi wireless network communication technology can solve problems of difficult communication between miners and mine managers, accurately location of mining personnel, complex terrain, too much monitoring points and requiring larger(More)
High mobility group box 1 (HMGB1), a non-histone nuclear protein, was associated with a variety of biological important processes, such as transcription, differentiation, extracellular signaling. As a cytokine or inflammatory mediator, more and more data showed that HMGB1 was involved in inflammatory diseases, cancers or autoimmune disease. However, few(More)
Firstly, in this paper we propose an improved immune algorithm, that is, introduce the Metropolis criterion into the selection operation of immune algorithm, and the Metropolis immune algorithm (MIA) is formed, then we carry out the theoretical analysis and experimental simulation aiming at the performance of the MIA; Secondly, we use this algorithm to(More)
This paper introduces a Smart Home Security System based on the technology of ARM9 and 3G communication. It uses S3C2410 hardware platform and Embedded Linux Operating System to implement the real-time display of the video images on the development platform. It presents the structure and work principles of the system, puts emphasis on the hardware(More)
Temperature effect modelling and analysis have been carried out on 0.25 &#x03BC;m gate length AlGaN/GaN HEMT grown on SiC substrate over the temperature range from - 40 to 150&#x00B0;C by on-wafer S-parameter measurements up to 50 GHz. The temperature behaviour of the DC and equivalent circuit parameters including f<sub>t</sub> and f<sub>max</sub> were(More)
Quantum chromodynamics (QCD) is the widely accepted theory of the strong interactions of quarks and gluons. Only through large scale numerical simulation has it been possible to work out the predictions of this theory for a vast range of phenomena relevant to the US Department of Energy experimental program. Such simulations are essential to support the(More)
By analyzing Vague Sets voting model, we bring forth a new method for approximating Vague Sets to Fuzzy Sets, and its general process is presented in the article. In a voting model, firstly, we suppose that the abstainers must vote for once more, and the results are close studied. Then the randomicity, uncertainty, and conformity of voting are found. As we(More)
In video processing, Automatic video object segmentation is an important and difficult problem, we propose an effective algorithm of automatic video object segmentation based on temporal-spatial information. Firstly, we obtain video object mask based on temporal, position and motional information, then correct the contour of the obtained video object mask(More)
Objective To investigate the effects of recombinant high mobility group box l (rHMGB1) on the differentiation of myeloid-derived suppressor cells (MDSCs) in vitro. Methods The cells were harvested from the bone marrow of BALB/c mice and cultured with rHMGB1, granulocyte-macrophage colony-stimulating factor (GM-CSF) combined with IL-6 (GM-CSF-IL-6), GM-CSF(More)
We introduce an algorithm of semiautomatic video segmentation and tracking by integrating background constructing and motion estimation. Firstly, we extract the video object of the initial frame using the artificial way, then, build the background of the initial frame, finally, the video object tracking is completed based on background updating, color and(More)
