Abstract: Reliability is the most important feature in this more and more complex computer system era. Fault injection is dependability validation technique to evaluating the system. Hardware and Software implementations of fault injection have a long history and are much more mature than simulated fault injection. In this paper, we compare the differences between these three types of fault injections at first. Then, we identify and understand the types of fault. We design a low-cost, simulation-based fault injection system and design experiments to verify the correctness.

Abstract: Magnetoacoustic Tomography (MAT) is a new imaging method. MAT combines the good contrast of electrical impedance tomography with the good spatial resolution of ultrasound imaging. Magnetoacoustic Tomography includes Magnetoacoustic Tomography with magnetic induction and Magnetoacoustic Tomography with injecting current. In this paper we researched the later imaging method mainly; in paper we studied the parameters of AC power supply, which was injected to the imaging sample. At the same time, the waveforms of experiment were given and analyzed, which provides theoretical basis for the selection of power supply used in the subsequent experiments.

Abstract: The general trend of tea technology development is tea industrial whole process automation. Pu'er tea with unique processing technology, its equipment with other tea varieties are very different. This paper summarizes the Pu'er tea industry mechanization and automation status, analysis of the tea industry automation process problems, proposed solutions and pointed out the development trend of tea industry automation.

Abstract: Improved color channel comparison method (ICCCM) is an effective method to transformcolor images into gray-scale ones. Based on the ICCCM, black or white insects could be effectively extracted and recognized from the real color images with bright background. Howeverit is difficult to use the ICCCM to extract and recognize the black insects from the realcolorimage with dark background. In this paper, the ICCCM is modified to transformthe color images into the gray ones, extracting and recognizing the black insectson the dark background. The ICCCM is modified as follows: (1) A threshold of the gray image is an average brightness value ofred (R), green (G) and blue (B) in all the image pixels.(2) The bright pixels and the color pixels have the highest brightness value 255 in the gray image.(3) A pixel brightness value of the dark area in the gray image equals to a minimum of R, G and B in the pixel. (4) After deleted all the pixels with a brightness value of 255, a threshold of the binary image is determined by Otsus theory. The modified ICCCM more effectively extracts and recognizes the black insects from the realcolorimages with dark background compared with the ICCCM.

Abstract: In this paper, research the influence on nozzle dimension in the sensitive element of fluidic gyroscope. Airflow of two different nozzle dimensions is analyzed contrastively in the sensitive element of fluidic gyroscope. Using ANSYS-FLOTRAN CFD software, the finite element simulation is conducted by a series of procedures, such as two-dimensional model building of fluidic gyroscope, meshing, loads applying and equation solving. The two dimensional airflow distributions of different nozzle diameters in sensitive element of fluidic gyroscope are calculated. The results show that, compared with large diameter and small diameter nozzle of fluidic gyroscope, airflow velocity in the outlet increases by 10.1%, and 31.3% of velocity in the nozzle in large diameter nozzle. It promotes airflow circulation and reduces airflow accumulation in the sensitive cavity without any vortex increase in large nozzle, it increases thermal wires temperature changes and improves the resolution and sensitivity of fluidic gyroscope.

Abstract: For assessing the joint operations command and staff objectively, the paper established a joint command personnel ability evaluation of multilayer index system. In view of the majority of interval-valued intuitionistic fuzzy information that is only used for single layer multi attribute index system. In the case of the two grade index attribute weights unknown, we utilized the score vector projection formula and obtained the pros and cons of the commanders in all levels under the one class index attribute. Finally we apply the ladder structure comprehensive assessment method to get the comprehensive ranking. It provide a certain basis for the selection of the joint operational commanders

Abstract: Study on the fine particle dispersion in the room is very important for creating and maintaining a healthy indoor environment. The paper presented a new dispersion model of fine non-spherical particles formulated in a Lagrangian way based on its dynamic characteristics. In this model, the effects of gravity, resistance, particles shape and random force were taken into account. The influences of gravity and non-spherical particles shape on its dispersion process were analyzed in theory. Simulation result and theory analysis showed the models established in the paper performed better than the random walk model.

Abstract: The cycle properties of-vertex connected graph are studied as follows pancyclicity and fully cycle extensibility. Two conclusions are drawn by way of argument: Let be a-vertex connected graph, if ,then is fully cycle extendable. Here the upper bound of is best possible. Let be a-vertex connected graph, if ,then is a pancyclic graph or .

Abstract: Level of Repair Analysis, for short LORA, is an integrated tradeoff technology and an important means that makes certain corrective maintenance support concept. Although by LORA it determines feasible, best efficient maintenance level or makes disposal decision for materiel repair, and affects design, life cycle cost and operational readiness of materiel, it is not mature for the development and application of LORA. In order to put the analysis technology into practice in deed, particular adapt to the need of integrated materiel support, on the basis of relative concept, principle and application of BP neural network in the paper, it discusses how to go on LORA in the context of integrated materiel support based on BP neural network, better to settle the problem of LORA.

Abstract: In view of the disfigurement that the former research mostly focus on the evaluation of the investment value before investment, not only this paper uses for reference to the former evaluation system, but also successfully integrates it into a unity that the evaluation before investment and after investment. This paper designs a set of evaluation criterion and a set of actual state evaluation system. Comparing both of them is the essential start of evaluation. Then according to it, and based on the grey correlation degree theory, this paper constructs a set of compositive evaluation indexgrowth imitating degree, The method provides a primary analysis frame for monitoring venture enterprise fostering.
