A new clustering algorithm for complex attributes was proposed based on feature similarity measurement idea in this paper. In the algorithm, the objects similarities were measured by complex attributes similarity function. Then, a graph model was constructed based on the similarity. Finally, the graph was divided to clusters. Compared with the traditional clustering algorithms based on selecting dimension...
Occupant distribution in buildings is important both for energy saving and for fast evacuation. This information can be monitored by wireless sensors, which are easy to install but subject to limited battery. In this paper, we consider the activation policy optimization of wireless sensor network for occupant distribution estimation under limited battery. Three contributions are made. First, we focus...
Chinese high-speed railway is undergoing a very vast development in recent years. How to efficiently maintain the high-speed railway system becomes an urgent task faced by the railway operator. In this paper, we study the random failure model of high-speed railway equipments in China, based on the statistical analysis of the real data of failure records. Several classical distribution functions for...
We propose a simple and new approach to generate the reconfigurable ultrawideband (UWB) pulse signal in optical domain. Phase modulation to intensity modulation conversion is utilized to obtain basic monocycle pulses with reversed polarity. Single mode fiber is adopted as dispersion media for introducing time delay between these monocycle pulses. By switching the taps coefficients, electrical monocycle,...
Based on the solution of homogeneous linear equations, we construct a specific verifiable secret sharing scheme in vector space. Then, we propose a new protocol for the verifiable redistribution of secret between different access structures without recovering it. Our verifiable secret redistribution (VSR) protocol can verify the correctness of subshares, at the same time it can tolerate faulty shareholders...
We propose a multi-wavelength all fiber laser incorporating Fabry-Perot filter and high nonlinear fiber. By employing this compact schematic, we are able to achieve 40-wavelength operation with the wavelength spacing of 0.2 nm and 3 dB spectral width of ∼0.016 nm.
Reflux hole plays an important role in the structure of the self-priming pump. Its position and area have a great influence on the self-priming capability and efficiency of the pump. In this paper, the numerical simulation of the internal flow field in the self-priming pump with different areas and positions of the reflux hole was conducted on the platform of Fluent. The simulation results show that...
Due to lots of measuring positions, long duration, complex test objects and various data types in the tracking test system, there is a badly need to find a simple, effective and convenient analysis method to process the test data and figure out the potential rules. This paper finds a method of identifying the optimal time-series model automatically, through studying different models and criterion...
Compared with the conventional plane LEDs, the nanorod LEDs will commonly have poor electrical properties. The dangling bonds at the side wall of nanorods will not only lead to the serious leakage current, but also decrease the hole density in p-GaN layer. It is necessary to passivate the dangling bonds to improve the electrical performance of nanorods LEDs. In this paper, by applying the standard...
The drastic growth in the consumption of electrical household appliances becomes a concerned issue in recent years. It is difficult for traditional methods to consider both subject's comfort and energy savings. Moreover, different people have different comfort preferences and requirements. In this paper, a novel integrated control method of blind and lights is proposed and it can provide an intelligent...
Intelligent building system attracts more and more attention in both academic and industrial communities. Learning human comfort requirements and incorporating it into building control system is one of the important issues. In the traditional HVAC control system, the thermal comfort and the acoustic comfort are often conflicted and we lack of a scheme to trade off them well. In this paper, we propose...
The piston stopping position directly impacts the next engine starting after engine flameout in idle stop system. The shutdown process of the gasoline direct injection (GDI) engine is studied by theory analysis and simulation experiments. The both mathematical model of the cylinder gas and crankshaft output torque are derived. The bench test system is designed for the GDI engine. By comparing the...
The creep performance of the lead-free solder joint Sn-0.7Ag-0.5Cu-3.5Bi-0.05Ni/Cu(SAC0705BiNi/Cu) was investigated and compared with that of the lead-free solder joint Sn3Ag0.5Cu/Cu(SAC305/Cu) after thermal shock by nanoindedtation. It was found that the indentation creep of SAC0705BiNi/Cu solder joint was lower than SAC305/Cu solder joint before and after thermal shock. The Creep rate sensitive...
By loss-allowing the two-sector profit model was extended and the strategies of international transfer pricing for multi-national corporations under centralized-decision, tariff, income tax, exchange rate and tax credit were discussed. It was discovered that the profit maximization of multi-national corporations corresponds to the transferring price at the break-even point of the branch when the income...
This paper first introduces modeling theory of GM (1,1) grey equidimensional filling vacancies, and establishes GM (1,1) grey forecasting model of equidimensional filling vacancies by using power demand load of Shan Dong Province from 2004 to 2011, then forecasts power load demand of Shan Dong Province in 2012 and 2013 for two years. When compared with the actual electricity load, that grey forecasting...
This paper investigates Multirate sampled-data control system optimization design by considering robust stability of linear time-invariant uncertain systems described by affine parameter-dependent model. Extend Lyapunov upper bound robust stability test to develop a new condition for robust stability test of such system and give out a reliable numerical algorithm. For a given compensator F, define...
Ovarian cancer SKOV3 cells were transfected for 48 hours by the mediation of LipofectamineTM 2000. CCK-8 kit and real time RT-PCR were employed to evaluate the effects of GLI1 mRNA transfection on the proliferation of SKOV3 cells, the apoptosis rates induced by paclitaxel and the cell cycle of SKOV3 cells following the treatments were measured with flow cytometry; and cyclinD1 protein expression was...
In a parameterized Markov decision process (MDP), the decision maker has to choose the optimal parameters which induce the maximal average system reward. However, the traditional policy iteration algorithm is usually inapplicable because the parameters choosing is not independent of the system state. In this paper, we use the direct comparison approach to study this problem. A general difference equation...

To investigate the significance of metastasis and invasion of MMP-9and BR1VIS1 in breast cancer stem cells. The tissues from 65 breast cancer patients were divided into two groups, with and without lymph node metastasis. the CD44+CD24-and Non-CD44+CD24-cells were separated from MCF-7 by immunomagnetic beads. ALDH1 and mRNA levels were measured by RT-PCR in different groups. The ability of metastasis...
