Software reliability estimation and application based on heterogeneous architectures

Systems engineering and electronics (2010)

Shen Xiang-heng

Architecture-based software reliability models are established during the early phase of software development.The models can perform a prior analysis of software reliability.It is a basic factor for software architecture change,edition update and upgrade.However,the early architecture-based models are most applied to homogeneous software architectures,which could not satisfy the requirement of multiple architecture software.Multiple architecture styles are firstly analyzed.Then,a heterogeneous architecture-based software reliability model is proposed.Finally,an available example is presented with the model according to the estimation steps.

A method of outdoor simulation of infrared radiance of targets

Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE (2009)

Jiang-tao Song Shen Xiang-heng Yingjie Zhao

Current research on infrared simulation often focuses mainly on infrared imaging simulation by computer and pays little attention to outdoor simulation of infrared radiation characteristics of targets. In order to simulate infrared radiance of targets outdoors, in this paper we propose a new outdoor simulation method on the basis of heating the cloth by electricity. There are two major contributions in the paper. Firstly, uneven distributing of temperature field of the cloth surface is considered and the long-wave thermal imager is used as a link of the temperature control system. On the basis of many experiments, the expression is concluded about the relation of the temperature obtained by the lone-wave thermal imager and the temperature obtained by the temperature control system and the environmental temperature at the experimental scene. Secondly, the influence of the environment at the experimental scene on the infrared radiance of the cloth surface is thought over. Thanks to two measures above, simulation precision of infrared radiance is made much better. The results of many outdoor experiments demonstrate the performance of the proposed approach.

Development of testing instrument of optical-axial parallelism for multi-axial systems

Journal of Applied Optics (2015)

Huang Xin Shen Xiang-heng Ye Lu Wu Jin Zhao Yu-yan

结合实际需要设计了一种精度高、便携性好，用于检测多光轴光学系统光轴间平行性的检测仪器。该仪器能够实现可见、红外与激光不同谱段任意两个光学成像系统间的光轴平行性检测。与同类其他仪器比较，该仪器的特点是光学系统结构均采用全反射设计，避免使用红外光学玻璃，在设计中减小和去除了影响仪器精度的一些因素，例如:去除了平面镜2个表面楔角的影响。仪器的主体采用完全对称的结构和积木式的组装方式，保证了仪器经温度循环实验和振动试验后检测精度优于5，满足使用要求。

Measurement of effectiveness of software testing

Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE (2013)

Bo Zhang Shen Xiang-heng Junjie Wang Chen Yuan

In order to detect the errors in the software as much as possible and produce the software products with high quality, it is particularly important to do the quality evaluation of software testing work. In this paper the author did research of measurement of effectiveness of software testing from three aspects of testing method, testing process and testing result. Summarized the present technology condition of measurement of effectiveness of software testing at home and abroad, improved model of measurement of process of effectiveness of software testing, did the experiment of white box testing coverage rate and got the rough measurement value. The use of the proposed measure the effectiveness of software testing methods, analysis of data collected metrics, and then proposed to improve software testing techniques and software testing methods, so that make software testing effectively exert its positive function.

Research on software defect prediction based on data mining

Yuan Chen Shen Xiang-heng Peng Du Bing Ge

As the development of computer technology, software system becomes more and more complicated. Because of human's ability limit, there must be a lot of defects generated in the software development life cycle. This paper reviewed the state of art in the field of software defect management and prediction, and presented data mining technology briefly. Finally, proposed an ideal software defect management and prediction system, researched and analyzed several software defect prediction methods based on data mining techniques and specific models (Bayesian Network and PRM). With this system, we can efficiently draw up some prevention and solution scheme to guide the development of new software.

A Method for Combinatorial Explosion Avoidance of AI Planner and the Application on Test Case Generation

Li Li D. Wang Shen Xiang-heng Mingli Yang

Combinatorial explosion is a key issue that leads to failures of planning for many planners. To avoid it, we modified the planner of IPP and divided its fact file into several small parts, and the method is called goal-decompounded. We also expanded the arithmetic of IPP. The modified planner we called MF-IPP able to handle multiple fact files, which avoided the combinatorial explosion. We applied the method on the GUI test case generation. The main idea was to produce the initial test case from planner firstly, and then propose a way of solution expanding to reinforce the generation. At last, we compared the performance of the two planners, and the result showed that MF-IPP can avoid the combinatorial explosion well.

New shafting error simulating method of photoelectric theodolite

Shen Xiang-heng

Shafting is the key module of photoelectric theodolite to decide the measurement precision.As measurement error brought by shafting error was deduced by the spherical trigonometry method with some simplification,the method had its limitation.According to the measuring coordinate of the photoelectric theodolite,the appearance process of shafting error was regarded as rotating course of the measuring coordinates,the shafting error was expressed by the rotating matrixes.A mathematic model for the influence of shafting error on the measurement error was built by a coordinate transformation method.Then a mixed-programmed method based on MATLAB and VB was introduced to simulate the shafting error model,and the error model was proved by comparing the simulating and calculating result with the spherical trigonometry method,which provides reference for precision analysis and error correction.
