Published: May 2014

To investigate the effect of autophagy induced by rapamycin (Rap) on proliferation of Human Leukemia Cells (HL60). HL60 cells are treated with rapamycin to induce autophagy. Then, Western blot is performed to examine the expression of Beclin1 and LC3. MTT assay is used to evaluate cell proliferation. The cell cycle is analyzed by flow cytometry (FCM). After treatment with rapamycin for 24 hours, LC3 is dramatically increased at protein level and autophagic activity is significantly increased. And MTT assay indicated that cell proliferation is inhibited by rapamycin. Compared with control group, more cells are arrested at G0/ G1 phases. We conclude that rapamycin can induce autophagy and suppress proliferation in HL60 cells.

Published: May 2014

For PFI (Port Fuel Injection) SI engine, accurate AFR (Air-fuel Ratio) control would keep TWC (Three-Way Catalyst) work in high efficiency range to achieve low pollutants emission. For ZS157FMI-3 motorcycle engine equipped with ZH600 ECS (Electronic Control System), a control strategy with close-loop feedback mode and feed-forward mode was designed for transient, quasi-steady and steady work states. One switching oxygen sensor was installed to form the close loop for quasi-steady and steady work states, and feed-forward control strategy based on a simplified fuel-film model was implemented to cope with transient AFR control. TP (Throttle Position) change rates were selected to be the determinant of which AFR control mode should be activated. For the validation of the control methods, bench tests were carried out in three typical work procedures. The results showed that AFR values of close-loop were close to stoichiometric one with relative error below 3%. AFR in acceleration or deceleration process may exhibit slight fluctuations, but the crest would be eliminated immediately. It concluded that the strategy designed in the study is able to cope with AFR control on variety of operation conditions for the experimental engine.

Published: May 2014

According to the image formation model and the nature of underwater images, we find that the effect of the haze and the color distortion seriously pollute the underwater image data, lowing the quality of the underwater images in the visibility and the quality of the data. Hence, aiming to reduce the noise and the haze effect existing in the underwater image and compensate the color distortion, the dark channel prior model is used to enhance the underwater image. We compare the dark channel prior model based image enhancement method to the contrast stretching based method for image enhancement. The experimental results proved that the dark channel prior model has good ability for processing the underwater images. The super performance of the proposed method is demonstrated as well.

To avoid traffic congestion’s becoming the obstruct of social and national economic development is the final goal that professionals in transportation field make great efforts to pursue. At the same time, with the increasing popularity of mobile phones, we can get a lot of phone base station data to identify the residents’ travelling track. Thus we can analyze the residents’ travelling behavior and get residents’ travelling patterns and mechanism. Also, residents’ travelling could be induced and guided in order that the condition of urban transport can be improved. Based on the above background, this paper is mainly based on mobile phone base station data and GIS data analysis method research on the urban transportation of residents’ travelling track.

The Simulation technology of OTV based on HLA was researched in this essay. Based on the technology, a distributed visual simulation system is established on the basis of HLA and STK, in which the space orbit transferring vehicle can fly around the low-orbit target, while hovering under the high-orbit target. The real time interactive simulation among the members that are located in different physical nodes of the system is implemented via their cooperation, and the scope of using the visual simulation is expanded as well.

Published: May 2014

The thermal stress field in the polysilicon was simulated and comparatively analyzed at different shapes of crucibes which have different types of a flat, a inverted-conical and concave bottom by COMSOL Multiphysics version 4.3a. The results indicated that: within the flat-bottomed crucible ,the isotherm in the crystal was slightly convex and the area of the maximum thermal stress was distributed in the bottom of the crystal edge and near the top of crystal edge; within the inverted-cone crucible, the isotherm in the crystal was straight and the area of the maximum thermal stress was only distributed in the bottom of the crystal edge; within the bottom of the concave crucible, the isotherm in the crystal was slightly concave and the area of the maximum thermal stress distributed in the bottom of the crystal edge was larger than that of the crystal within the first two kinds of crucibles. To sum up, the inverted-cone crucibe was beneficial to reduce the thermal stress distribution in the polysilicon which could provide theoretical guidance for improving the production process of the polysilicon.

This paper further analyzes some existent problems of coupling vibration equations of water hammer, based on the improved continuity equation, it is derived simply for calculating coupled water hammer vibration, comparison with continuity equation that is to be used widely, the new continuity equation is basically consistent with commonly used continuity equations, so, the improved continuity equation can be used to calculate water hammer based on fluid-structure interaction (FSI).
Fast Ellipse Detection Method Based on Coordinates Transformation
Authors: Wang Cheng
Published: May 2014

In this paper, we introduce a new method for ellipse detection. For any object has closed curve in a digital image, it is easy to calculate the centroid of the object. We assume the object is an ellipse, and then by rotating, scaling this object, it can be transformed to a circle. So, ellipse detection problem becomes circle detection problem. Compared with other detection methods, our method only need process border points of the object, hence has higher detection speed.

Published: May 2014

Air defense process of large surface warship formation is a very important part in the combat. In current research, however, less attention has been paid to the whole process of air defense of surface warship formation in macro perspective. This paper applies the PEPA method to model the air defense process of surface warship formation. The cooperation among elements has been taken into account in the established model and the basic process of the air defense has been described as well. By analysis it shows the performance of air defense of warship formation increases with the increase of elements’ quantity, and finally reaches a stable value. Then the composition of the basic formation elements that the interception capacity of air defense operation attains the maximum can be obtained from the test results. Therefore, it provides a new quantitative method to deal with the air defense problem of warship formation.
