Authors: Zhang Yang , Wang Yuan , Yang Bin
Published: September 2013

The particle tracking velocimetry (PTV) algorithm is one of the most important branches in the flow visualization research. An efficient two-frame PTV based on Delaunay tessellation was updated by a novel concept called Dual Computation. The updated algorithm was tested using CFD flows with changeable parameters and random erasing of particles as perturbation. In addition to the simple structure and the minimal dependence on algorithmic assumptions, the advantages of this updated algorithm also include the high accuracy in addressing complex flows with noticeable ratio of particles having no match.

Authors: Liang Xi Kun , Tao Li Min
Published: September 2013

Aiming at the limitation to the credit evaluating system of C2C, a multi-variables fuzzy reasoning model is constructed and the calculating scheme is designed to evaluate the sellers credit of C2C referring to the evaluating indexes of Taobao net. The score of credit indexes is defined by the form of continuous interval in the model based on the interdependent relationship between the global assessment and the secondary evaluation indexes. Since the effect of the subjective factors on credit rating is efficiently eliminating in the algorithm and the credit description is more close to the transaction fact, the rating results of credit got by fuzzy calculation is more reliable than the ones obtained by traditional evaluation method. To verify the effectiveness of the fuzzy method, an applied example is given under the background of Taobao transaction.

Published: September 2013

As the explosion of digital information in network, data de-duplication has been widely used in most backup systems to improve space efficiency. When only unique data segments are stored and shared by backup files, the reference information between the files and their data segments is becoming more and more important to track the data usage and reclaim of freed space. However, as the usage of multi-core and many-core, genereal Group Mark-and-Sweep method has some poor performance in concurrent reference updates due to the synchronization overhead. To alleviate this challenge, a Parallel Mark-and-Sweep mechanism has been exploied based on the research of DHT and similrity method. In our experiments with real-world datasets, it has shown a better performance comparing to the sequential method.

Published: September 2013

The perturbed-chain statistical associating fluid theory (PC-SAFT) is used to correlate and predict the phase equilibria and the triple point pressure of CO2 and ethanol binary mixtures. The binary interaction parameters (kij) are regressed by fitting to the experimental data of mixtures. The vapor-liquid equilibria and liquid-liquid equilibria of the mixtures are investigated and the influence of temperature and pressure on the phase equilibria and the triple point pressures is demonstrated. Our results show that the pressure dependent kij can describe the phase equilibria of CO2- ethanol mixtures quantitatively well.

Many researchers try to detect the application of explicitation in the literature text but there are great limitation in the political text .The purpose of this research is to detect the prominence of explicitation strategies in Selected Works of Deng Xiaoping, Volume III (1982-1992) with the help of the Chinese English parallel corpus, both quantitative and qualitative methods are adopted. It is found that in the target text the percentage of the connective words of reason and result which were added or explicated comes to 21.96%.

This paper from the perspective of phonology, phonetics and statistics,combining the three basic principles, to describe and research the phoneme system of 5190 Tibetan consonant of modern library within the closed space. According to the statistics and analysis of the initial and final distribution pattern, the structure types of initial and final, the relationship between Tibetan parts and the structure of initial and final in modern library of 5190 Tibetan consonant, the study found that, 1) the frequency distribution of the modern Tibetan initials is in equilibrium state, and the frequency distribution of finals is centralized,2) the combination ability of base-word initials is significantly higher than other initials which by the combination of basic word and other components,3) the combination ability of a and the combination of a with add-back letter is the strongest in all finals. This paper provides data and certain reference value for the further study on Tibetan phoneme of modern Tibetan.

Optimization research of firing interval is applied to improve firing density level of MLRS. Firstly, the finite element model of MLRS is built to obtain the dynamic response of the launch guider muzzle and the rocket initial disturbance is calculated. Secondly, the equation of exterior ballistic is solved using Monte Carlo simulation and Runge-Kutta method and with mathematical statistic method the estimate of dispersion is obtained. Thirdly, modal analysis for MLRS is carried out and the new firing interval is proposed combined with the dynamic response obtained above. Finally, substitute the new firing interval into the model of MLRS, the results show that the new firing interval shorten the firing time by 21.4% and improve the firing density effectively without affecting the dispersion of the MLRS.

In order to increase the useful life of sleeve, improve the organizational structure and reduce costs, ZA alloy materials can be used as a raw material using cold extrusion technology for production. The main content of this paper is simulating the change rules of the equivalent plastic strain, the equivalent stress and the flow in the forming process of ZA alloy in different extrusion speed and friction coefficient condition by finite element technology, making a contrastive study with the extrusion theory, and finding out the most appropriate extrusion processing parameters. The results not only provide sufficient theatrical support for the cold extrusion process of sleeve of ZA alloy, but also offer some new thoughts for the design of extrusion mold.

China is one of the largest coal producer and consumer countries in the world. However, due to the complexity of coal resources, storage conditions, geological disaster-prone coal mines, it is also a coal mine accidents multiple country, coal mine accidents and deaths of China accounted to about 80% total of the world. In the coal mine accident occurred, roof accident has accounted for around 40%,such as the roof collapsed, slipped, deformation, obstruction and so on. So the monitor and early warning of roof is particularly important. State of motion is closely related to mine roof pressure. Roof support pressure or resistance can be measured by the pressure sensor. Applied time series theory analysis and forecasting future pressure changes, can master the roof movement trends and regularity, guide safe production. So the decisions have some practical significance.
