As the existence of objective and subjective factors in developing software, changes in requirements is inevitable, often lead to changes in program modules also. Because of correlation among program modules, to modify a module may lead errors to related modules. Put forward to establish association diagrams of modules, and use methods of traversal of graphs, to fast track, positioning error or affected modules, and narrow test range, to some extent which improve the efficiency of software testing.

In order to explore optimization effects of RETC software and intelligent algorithms, including genetic algorithm, simulated annealing algorithm and particle swarm optimization, on parameters of Van Genuchten(VG) Equation for the soil water characteristic curve of urban green space, the soil drying curve of green space was obtained by using the tensiometer method in this study, where RETC software, genetic algorithm, simulated annealing algorithm and particle swarm optimization were constructed to solve parameters of VG Equation. The results indicated that the parameter fitting results of VG Equation determined by RETC software and three intelligent algorithms were very close to experimental results with a very high simulation accuracy(R2=0.996) in given conditions, moreover, the fitting effect of intelligent algorithms was better than that of RECT software.

To solve the problem of Web services integration, a Web services-based integration environment of an automatic identification system was proposed and implemented, which included encapsulation of Web services with specific function based on the original function module, service integration achieved through enterprise service bus as well as message transmission mechanism, and implementation of the management client. It follows and supports the international open specifications, such as WSDL(Web Services Description Language) 、 SOAP(Simple Object Access Protocol),and provides good solution for Web services integration.

Location based services (LBSs) cover a wide range of services through providing location related information. In the provision of services, that user's actual position can not be rightly displayed on the digital map of mobile terminal is one of significant issues and plays a vital role in LBSs. In this article, we call this phenomenon as the problem of map-matching. The performance of map matching will obviously affect the quality of location based services. Mismatching or matching at low accuracy may result in wrong location service or cause great loss of either commercial or industrial activities. Therefore, issues regarding the location matching uncertainties have formed a research spot and related issues need to be solved in LBS. However, most of the studies on map-matching purely focus on algorithms, and not fully on position methods, coordinate transformation and geocoding. In this paper, all of above are comprehensively presented to deal with the map matching uncertainties.
