Inverse sampling is one of the hot topics in the continuous sampling process. It is considered to be a more appropriate sampling scheme than the usual binomial sampling scheme when the subjects arrive sequentially and the underlying response of interest is acute. In this paper, we propose five confidence interval estimators for the relative difference in 2×2 table under inverse sample. The performance...
With reference to the intellectual property in commercial banks, patent right, trade mark right, and copy right are the three main aspects, in the protection of which the Chinese banks have some shortcoming and deficiency. To strengthen the intellectual property protection in Chinese banking, this essay proposes that the banks themselves should improve the interior protection and management systems...
In this paper, based on a two-dimensional (2D) transient magneto-hydrodynamic (MHD) model, HCVA under different interruption conditions was simulated and analyzed. The simulation results of power-frequency current show that the simulation results of the transient model are the same as those of the steady-state model, as the varying time of current is much longer than the relaxation time of plasma...
The resources allocation and the dynamic environment determine enterprises performance, and dynamic environment directly affects on business performance, but also indirectly affects the relationship between resources allocation and performance. This paper got resources allocation factors and dynamic environment factor by principal component analysis. Empirical results showed that financial resources...
The measurement of lightning current is essential to lightning protection in grid, because only if accurate amplitude and waveform of the lightning current is obtained can the correct lightning protection measures be taken. However, in a high voltage power system, it is almost impossible to measure directly the lightning currents accurately and safely. So aiming at solving the problem of accurate...
In this paper, the partial feedback linearization was made for the non-linear model of the triple inverted pendulum, by means of the differential geometry. Then the simulation and analysis of tracking control and interference control were made, which combined with the human simulating intelligent control and LQR control in the system. The results show that the human simulating intelligent control...
Research on county public expenditure performance evaluation system, not only create conditions for more effective, results-oriented performance budgeting reform, but also provide direction of enhancing the capacity of public services for the grass-roots government. This paper attempts to construct the county public expenditure performance evaluation index system, in order to objectively evaluate...
Fractal coding is a recent and effective compression technique based on self-similarity of images. However, its encoding time is very high. In addition, when 2-D fractal coding is applied directly to field-sequential stereo video sequences, the high vertical-frequencies of stereo image pairs are suppressed. This makes the depth perception defective. In this paper, a survey of fractal coding development,...
This paper realizes the fusion of multi-dimension oil monitoring data by the way of principal components analysis, gets the trend curve representing the degree of wear about the equipments, keep the wear information contained in the monitoring sample to a maximum limit, which is very important to the forecast and support of equipment technology condition.
Nanoengineered metal materials with the property of surface enhanced fluorescence (SEF) are attracting considerable attention due to their promising contribution to the fields such as biosensing and photonics by lowering the limit of detection (LOD) and enhancing the illumination efficiency. A variety of SEF materials such as nanoantennae [1, 2] and nanoparticles [3–8] have demonstrated significant...

The system mainly consists of two illumination sources, two cameras, two sensors, an IPC, an interface circuit, two eliminating devices, a set of algorithms for image processing and a software for the control of independent binary-channel...
The control strategy and parameters matching is critical for the performance of high-speed tracked vehicle with hydrostatic drive that is composed of engine, hydraulic pumps and motors. Based on the analysis of characteristic of engine and pump working together, the pump displacement control strategy is proposed and applied in order to accomplish the aim torque and power of engine. Motor displacement...
This paper presents a new steady-state productivity equation for horizontal wells in gas reservoirs with upper and lower boundary enclosed. Firstly, the fundamental solution to the 3-D steady-state Laplace equation is derived with the philosophy of source and the Green function for a horizontal well located at the center of the laterally infinite gas reservoir, with considering the above boundaries...
This paper explores the control of non-Markovian systems via coherent quantum feedback. In the spirit of classical control theory that is widely used in engineering, we acquire completely new insights in the closed-loop design from the frequency domain point of view, which appears missing in quantum control theory. Based on the non-Markovian Langevin equation for the closed-loop quantum dynamics,...
This paper presents an iterative autofocus approach to improve the performance of compressed sensing (CS) in synthetic aperture radar (SAR) imaging in the case of model error. Combined with the least square (LS) regularization technique and the minimum mean square error (MMSE) focusing method, the approach can solve a joint optimization problem to achieve model error parameter estimation and SAR image...
Projection pursuit regression is used to make model about the combustion chamber and total sound level of the combustion chamber in order to fit total sound level of An Aircraft Engine. At last the average relative error is small to indicate the model is better, so it is important for aero-engine design and reliability analysis.
The key objective of this research is to reveal the change of the Oriental white stork's habitat due to local agriculture activities in the study area at landscape scale with the aid of Geographic Information System techniques. Furthermore, an analysis of breeding captivity is done for a better understanding of the relationship between the decrease in Oriental White Stork population and habitat loss...
The increasing complexity of engineering systems has sparked rising interests in multidisciplinary design optimization (MDO). However, the main challenges in MDO are its computational expense and complexity structure. Therefore, to address these challenges, this paper focuses on a new MDO method, interaction prediction optimization approach, which is a design architecture applied in the multidisciplinary...
