virtual experiments have been used in education for a long time. However, most of the virtual experiments are modeled only for some special subjects, and are programmed case by case. To handle these problems, an online system of virtual Educational Experiments (VEEs) is designed to develop various virtual experiments and simplify the virtual experiment modeling by reusing the existed experiment components. Based on the system of VEEs, we proposed a method of modeling and visualizing dynamic experiment components. Firstly, the dynamic experiment components are modeled based on the combination of images and graphics. Then the visualization of the dynamic experiment components is designed for multidisciplinary virtual experiments. The system has been running in some colleges and universities for several months. The tests show that it can rapidly model dynamic experiment components and realistically visualize the dynamic experiment components for the system of VEEs. © 2011 IEEE.

This article proposes a method of constructing a ping-pong system via marker less real rackets in collaborative augmented reality. Except a pair of video cameras, without any other sensors or artificial markers, users can use real rackets to hit virtual ping-pong ball on a virtual table and interact with remote partners in augmented reality scene just as they were playing ping-pong in the same place. First, the real racket can be detected and tracked in real-time in the video captured by a single camera in each site. By 3D registration, the real racket can seamlessly interact with the virtual ping-pong ball and table. Then, a communication scheme is designed for the consistent perception between users in collaborative augmented reality ping-pong system. To achieve real-time interaction, the whole method is implemented in a parallel computing environment through multi-core processors. Experimental results demonstrate that our system can provide consistent perception and natural user interaction with low latency and high precision. © 2011 IEEE.

Rendering virtual objects into real scenes with real illumination can greatly increase the realism of virtual objects and the consistency between the virtual and the real. The main challenge lies in illumination estimation from a single image. This article proposes a novel method of single image based illumination estimation for lighting virtual object in real scene. Only a single image, without any knowledge of the 3D geometry or reflectance, is needed, which greatly increases the applicability of the method. We first estimate coarse scene geometry and intrinsic components including shading image and reflectance image. Then the sparse radiance map of the scene is inferred based on the scene geometry and intrinsic components. Finally, the virtual objects are illuminated by the estimated sparse radiance map. Some experimental results show that this method can convincingly light virtual objects into a single real image, without any pre-recorded 3D geometry and reflectance, illumination acquisition equipments or imaging information of the image. © 2011 IEEE.

To find the best memory system for emerging workloads, traces are obtained during application's execution, then caches with different configurations are simulated using these traces. Since program traces can be several gigabytes, simulation of cache performance is a time consuming process. Compute unified device architecture (CUDA) is a software development platform which enables programmers to accelerate the general-purpose applications on the graphics processing unit (GPU). This paper presents a real time multi-core cache simulator, which was built based on the Pin tool to get the memory reference;and fast method for multi-core cache simulation using the CUDA-enabled GPU. The proposed method is accelerated by the following techniques: execution parallelism exploration;memory latency hiding;a novel trace compression methodology. We describe how these techniques can be incorporated into CUDA code. Experimental results show that the hybrid parallel method of time-partitioning combines with set-partitioning presented here is 11.10× speedup compared to the CPU serial simulation algorithm. The present simulator can characterize cache performance of single-threaded or multi-threaded workloads at the speeds of 6-15 MIPS. It can simulates 6 cache configurations within one single pass at this speeds compared to CMP$im, which can only simulate one cache configuration each simulation pass at the speeds of 4-10 MIPS. © 2011 IEEE.

This article proposes a novel image-based method to transfer illumination from a reference face image to a target face image through edge-preserving filters. According to our method, only a single reference image, without any knowledge of the 3D geometry or material information of the target face, is needed. We first decompose the lightness layers of the reference and the target images into large-scale and detail layers through weighted least square (WLS) filter after face alignment. The large-scale layer of the reference image is filtered with the guidance of the target image. Adaptive parameter selection schemes for the edge-preserving filters is proposed in the above two filtering steps. The final relit result is obtained by replacing the large-scale layer of the target image with that of the reference image. We acquire convincing relit result on numerous target and reference face images with different lighting effects and genders. Comparisons with previous work show that our method is less affected by geometry differences and can preserve better the identification structure and skin color of the target face. © 2011 IEEE.

The existing penetration testing systems need to rely on the professional skills in the testing process, so they increase the penetration testing of human resources and costs. While it also reduces the efficiency of the test, it increases the test cycle. This paper presents a new penetration testing scheme by an automatically generated method. Through penetration testing scheme description, we establish an automatic generation system about penetration testing scheme, and the automatic generation penetration testing scheme for network analysis model (AGPTSAM) is established, and then the termination of the AGPTSAM is proved by the pushdown automaton. The prototype system of AGPTSAM is implemented. The penetration testing scheme could provide guidance and basis for the implementation of the penetration testing system, and shorten the test cycle and the human resources cost. This method is verification of effectiveness by experimental which works on the implementing platform. © 2011 IEEE.

Penetration testing is widely used to help ensure the security of the network. Traditional penetration testings were manually performed by tester according to scheme, the process is usually complex resulting in that it is labor-intensive and requires tester to be familiar with all kind of tools. So it is very desirable to use a unified method to describe the scheme which can be identified by computer, then the computer can be used to substitute for tester to perform penetration testing. A new method is presented to describe penetration testing scheme. We propose a language for tester to describe the penetration testing scheme. Based on the conceptual model of penetration testing scheme we design the penetration testing scheme description language (PTSDL) and outline the important EBNF. PTSDL is declarative abstracting the process of penetration testing which makes this language flexible, extensible and adaptable to new penetration testing method. Use of this language is illustrated by an experimental study, which shows that the language can effectively describe the penetration testing scheme. © 2011 IEEE.

Cross-domain interoperation based on role-mapping increasingly becomes a representative research field of collaborative environment. However, in this collaborative environment, there would still be more permission or less than the role of role-mapping policy required when authorization, this situation can not be completely avoided. This disaccord will result in conflict of access control policies (ACPs) in collaborative domains, and ultimately lead to unauthorized access to resources in autonomy domains. A new method is presented to detect the conflict between access control policies in collaborative environment automatically. The ACPs conflict detection model (ACPCDM) is established, the termination of ACPCDM is proved by the putdown automation, and the prototype system is implemented. At last, we validate the validity of this method with experiments, the result of the experiments shows that the analysis report of conflict can not only detect if there is conflict, but also figure out the conflict type, the causes and location of the conflict. So it is much easier for administer in each domain to resolve the conflict. © 2011 IEEE.

Realism and simplicity of virtual experiment scene building can influence the usage of virtual educational experiment applications. This paper proposes an image based method of experiment scene building for virtual Educational Experiments. Firstly, virtual educational experiment components are extracted from images of experiment instrument by using the interactive method of object extraction. Then, the corresponding logical model descriptions are attached to the extracted components. Finally, the components required in a specific experiment are inserted into the selected virtual experiment scene and are connected interactively. A routing algorithm based on equivalent connection line is designed to make the generated line connections between components clear and legible. A virtual experiment scene building system, named VE Scene builder, has been implemented and widely used. The feedbacks demonstrated that our system can rapidly generate realistic and legible virtual experiment scene. © 2011 IEEE.
