Heavy-ion collisions(HICs)is a unique experimental tool for investigating the properties of nuclear matter under extreme conditions in the laboratory.At HIRFL-CSR energies,HICs can create nuclear matter with 2-3 times the saturation density(ρ0).The HIRFL-CSR external-target experiment(CEE)is a large-acceptance spectrometer designed to explore frontier topics in high-energy nuclear physics,such as the QCD phase structure and nuclear matter equation of states.In this letter,we introduce simulation and analysis software for the CEE experiment(CeeROOT).Based on the CEE conceptual design and CeeROOT software,the configurations of its subdetectors were optimized by considering foreseeable physical constraints.The final detector layout of the CEE spectrometer and its acceptances were validated through simulations of U+U collisions at 500 MeV/u and pp collisions at 2.8 GeV,which demonstrated that the CEE experiment will serve as a detector with wide acceptance and multi-particle identification capabilities for studying high-energy nuclear physics topics at HIRFL-CSR energies with pp,pA,and A A collisions. 展开更多

In view of the flaws of component-based software （CBS） reliability modeling and analysis, the low recognition degree of debugging process, too many assumptions and difficulties in obtaining the solution, a CBS reliability simulation process is presented incorporating the imperfect debugging and the limitation of debugging resources. Considering the effect of imperfect debugging on fault detec- tion and correction process, a CBS integration testing model is sketched by multi-queue muhichannel and finite server queuing model （MMFSQM）. Compared with the analytical method based on pa- rameters and other nonparametric approaches, the simulation approach can relax more of the usual reliability modeling assumptions and effectively expound integration testing process of CBS. Then, CBS reliability process simulation procedure is developed accordingly. The proposed simulation ap- proach is validated to be sound and effective by simulation experiment studies and analysis. 展开更多

This study presents three kinds of skid-mounted plants, including single mixed refrigerant cycle （MRC）, nitrogen expander cycle, and natural gas （NG） Claude cycle. Hysys simulation shows that single MRC is the most efficient cycle among the three. The specific power of single MRC liquefiers is 1 485 k.l/kg, 15% higher than that of large liquefaction process. Considering the recovery of stranded-gas, commercial analysis suggests that the initial cost of LNG plants ranging from 1 to 100 ms/day can be paid back in 2 to 4 years. 展开更多

This study presents a decision making process in three steps of knowledge management for test organization using process simulation and financial analysis. First, project cost assessment of test knowledge management process subjects to different project duration and number of staffs. Two knowledge management simulation models representing experienced personnel with knowledge sharing and inexperienced personnel with internal training respectively are employed to contrast test personnel capability. Second, performance evaluation of software testing process by different personnel capability is conducted to simulate system test using three project metrics, namely, duration, effort cost, and quality. Third, a comparative financial analysis is prepared to determine the best solution by return on investment, payback period, and benefit cost ratio. The results from three stages of finding are discussed to arrive at the final scenario. We provide a case study evaluating how software testing industry needs to build effective test organization with high quality personnel for sustainable development and improvement. 展开更多

Modelling and simulation has become an important tool in research and development. Simulation models are used to develop better understanding of the internal properties and impact of various parameters on the final quality of the product or process. Simulation model reduces the number of experiments and saves the wastage of material, time and money and are widely used in automobile industry, aircrafts manufacturing, process engineering, training for military, health care sector and many more. Wood Plastic Composite （WPC） is a bio-composite made by mixing wood fibers and plastic granules together at high temperature by compression molding or injection molding. A large quantity of WPC is rejected due to poor quality and low mechanical strength. There is a need to improve the understanding of the wood plastic composites, with both theoretical and experimental analysis. The impact of various parameters and processing conditions on the final product is not known to the industry people, due to less simulation models in this field. A new simulation software WPC Soft is developed to predict the mechanical and thermal properties of WPC. The software can predict the mechanical and thermal properties of WPC. The simulation results were validated with the experimental results and it was observed that the predicted values are quite close to the experimental values and with the further refining of the model, prediction can be further improved. The present simulation software can be easily used by the industry people and it requires very little knowledge of computers or modeling for its operation. 展开更多

This paper probes into modeling and simulation of direct-sequence spread spectrum communications system based on software radio. The simulation result shows that the spread spectrum communication system that uses software radio technology has good anti-interference ability. Even there is much interference, the normal communication still can be guaranteed. At the same time, this digital direct spread intermediate frequency system has a good generalization. The required functions can be realized by changing software. It shows that using software radio technology to transform spread spectrum system has remarkable effects. 展开更多

Slope stability analysis is an important research direction in geotechnical engineering and levee engineering. Because the deformation and displacement have a significant impact on the stability of the structure, the analysis of the deformation and displacement of the slope is the most important. The computer simulation software is used to simulate the deformation and failure process of the slope. According to the simulation results, the data analysis method, rigid body limit equilibrium method and other methods are combined to improve and improve the safety of the slope. Relative prevention measures are provided for different failure forms, so that the slope construction is safer and more economical in practical projects. 展开更多

Addressing the complexity of quality evaluation during the R&D phase of the waterflooding sandstone reservoir numerical simulator(OSIM),this study establishes a comprehensive assessment framework driven by clientside requirements.The novelty of this work lies in the integration of a client-driven 146-indicator hierarchy specifically tailored for iterative simulator R&D.First,a hierarchical software quality evaluation model is constructed,encompassing four primary dimensions and 146 secondary indicators.To mitigate the subjectivity inherent in traditional weight assignment,the Fuzzy Best-Worst Method(FBWM)is employed to determine indicator weights.Subsequently,the Technique for Order Preference by Similarity to Ideal Solution(TOPSIS)is integrated to develop a composite ranking algorithm,coupled with specific protocols for acquiring indicator values were established using an 80-case model library.Finally,the proposed framework is validated using nine iterative versions of OSIM and the Commercial Software(CS).Results indicate that the final OSIM version achieved a superior overall ranking with a composite score of 0.962,surpassing the Commercial Software’s score of 0.944,verifying the effectiveness of the method.The Root Mean Square Error(RMSE)for field water cut was controlled within 1.8%,demonstrating high simulation precision.This methodology exhibits strong universality,offering a scientific reference for the quality assessment of various reservoir simulators,including thermal and chemical flooding. 展开更多
