In order to make software developers understand the object responsibility and operation process of technology close-loop, we study the modeling methods about quality problem technology close-loop. Based on the analysis of key activities, extracting the close-loop class and operation activity, we study the extracted rules of class and activity. To effectively describe the detail of close-loop activity, the extracted close-loop class and operation activities are formalized by B method. The translated rules are studied from close-loop class and operation activity to B abstract machine. An example is given to demonstrate the proposed methods, which provides an effective model with clear object and explicit process about technology close-loop

With the centralization of measurement assets, standardized management and the launch of a new generation of RFID smart electricity meters, the traditional methods of man-machine verification of electricity meters have been unable to meet the demand. In order to realize the verification of RFID smart electricity meters and improve the verification efficiency and the informatization management level, and liberate the labor force of inspectors, on the basis of existing smart meter detection system, this paper designed a new intelligent detection system based on RFID smart electricity meter. RFID technology is applied to the smart electricity meter verification system. The system can meet fully automatic verification of RFID smart meters, and effectively track and record the verification data of RFID smart meters, which greatly improves the verification efficiency.

The Single Carrier Frequency Domain Equalization (SC-FDE) system can effectively work in frequency selective fading channels. The Iterative Block Decision Feedback Equalization (IBDFE) is efficient nonlinear equalization in SC-FDE systems. However, the computational complexity is high and the complexity is proportional to the number of iterations. In this paper, a low-complexity IB-DFE is proposed. The transmitted symbols go through a linear equalizer based on the minimum-mean-square-error (MMSE) criterion and the estimated symbols is as the output of the conventional feedback equalizer. The feedforward equalizer structure remains the same. Compared with the conventional IBDFE, the iteration is cancelled and the implementation complexity is reduced. Simulation results show that the performance of the proposed simplified design is similar to the traditional iterative IBDFE under frequency selective fading channels, but it imposes a lower complexity than the conventional IBDFE.

Because of the mismatch of material properties between silicon and glass, especially the mismatching thermal expansion coefficients, the Micromechanical Silicon Resonant Accelerometer based on the Deep Dry Silicon On Glass (DDSOG) technique is seriously affected by the temperature during the fabrication, packaging and use processes. Based on the working principle and temperature characteristics of Micromechanical Silicon Resonant Accelerometer, the effect of the mismatching thermal expansion coefficients of silicon and glass is analyzed, and a Single-Anchor-Supported accelerometer structure with low temperature sensitivity is designed. Simulation results show that the structure can effectively reduce the effect of mismatching thermal expansion coefficients of silicon and glass.

In this paper, the finite-time stability of a class of fractional order nonlinear systems is studied. By using the finite-time stability and the sliding mode control theory, a new dynamic sliding-mode controller is proposed, which will restrain the chattering and accelerated arrival at the sliding surface. The finite-time stability of the fractional-order nonlinear systems with external disturbances and uncertainties is achieved under the designed controller. Finally, one typical examples of three-dimensional fractional order Lorenz system are used to demonstrate the effectiveness and feasibility of the designed controller.

With the increasing popularity of "online learning", a method of finding effective learning materials from massive resources is urgently needed. By setting the "problems" in the online learning system as an example, this paper analyzes the "difficulty" of learning materials and proposes a computational method of difficulty. Then, based on the difficulty of problems and the concept of "typicality" in psychology, an algorithm suitable for problem recommendation is designed. The comparative experiments based on the actual data prove that this algorithm is superior to the existing methods both in the recommendation effectiveness and the time efficiency.

The previous research paid less attention to the similarity characteristics of gas liquid two-phase flow in space rocket engine thrust chamber, and the droplet motion analysis based on gas flow had never been carried out. In this paper, firstly a numerical analysis model about gas flow in thrust chamber is built and the gas flow similarity is deduced, then a dimensionless calculation expression is promoted to describe the gas flow velocity. Secondly, a numerical analysis model about droplet motion in thrust chamber is built, taking the gas flow as input. Lastly, the effects of the combustion length diameter ratio and outlet throat area ratio on the droplet trajectory and velocity are discussed. The analysis method, that is given in this paper and used to investigate into the droplet motion and gas flow in space rocket engine thrust chamber, has certain reference value for space rocket engine test and engineering design.

There are several non-ideal factors in the hardware implementation of Modulated Wideband Converter (MWC), which is an efficient sub-Nyquist system for sampling the sparse multiband signals. The non-ideal lowpass filter is one of these factors and can distort the reconstructed signal. In this paper, we concentrate on how to eliminate the impact of non-ideal lowpass filters and propose a new compensating method which can correct the non-ideal characteristic of actual lowpass filters. This solution remedies for the Fourier coefficients of samples in frequency domain with a bit more oversampling, compared to the standard MWC. The direct compensation in frequency domain is intuitive to acquire the Fourier compensating coefficients. And numerical simulations demonstrate that, this method can compensate many kinds of lowpass filter no matter what radical fluctuations and non-linear phases in the pass band of the filter.

The traditional crop classification uses artificial method all along, which has high cost and low efficiency. An automatic sorting method based on machine vision is proposed in this paper. Firstly, the non-uniformity correction of the CCD original signal is performed. Then the correction signal is converted from RGB color space to HSV space. The floodfill algorithm can obtain target pixel threshold value. The threshold segmentation data of the HSV color space is used to extract the target material. Finally all the pixels of the full image are divided to determine the location of the target material. The purpose of sorting the color and size of the material is achieved.
