Development and Realization of a Street Driving Simulator for Virtual Tour..!

Abstract- The paper describes the creation of a street driving simulator for virtual tour. The simulator uses real-time interactive virtual environment technology to immerse visitors in a 3D reconstruction of some main streets of Wuhan. Visitors can sit in and operate the simulator to tour fifty kilometer long streets of the city modeled in high-resolution 3D graphics. In this project supported by City Planning Exhibition Hall of Wuhan a car driving simulator is integrated for visitors virtual tour. This paper presents the challenges associated with realistic replication of driving with special emphasis on street tour simulation. The development and realization of the new simulator and its subsystems are detailed. Equipment, 3-D database, simulation program, and interfacing elements of the simulator are presented

Evolutionary Unit Testing of Object-Oriented Software Using A Hybrid Evolutionary Algorithm..!!

Abstract- Evolutionary algorithms have been successfully applied in the area of software testing. However, previous approaches in the area of object-oriented testing are limited in terms of test case feasibility due to call dependences and runtime exceptions. In this paper, we present a search-based approach to automatically generating test cases for objectoriented software. It relies on a tree-based representation of method call sequences. Strongly-typed genetic programming is employed to generate method call trees which respect the call dependences among the methods. We apply a new kind of distance-based fitness function that accounts for runtime exceptions. In a case study, the approach outperformed random testing in terms of achieved coverage and it produced test cases achieving full branch coverage for a test object that makes ample use of explicit runtime exceptions.
