Terrain visualization plays important role in the area of computer graphics. To meet the special requirements in visualization of large-scale terrain, an algorithm based on Level of Detail （LOD） is proposed for large-scale terrain visualization in real time. Triangle bin-tree is used in the algorithm to simplify the procedure of terrain, and a novel nested error metric sphere is proposed to compute errors based on screen and roughness which avoids T-junction and crack. To improve efficiency, presented method takes advantage of frame coherence to make location adjustment between the two required LODs, and uses time delay to reduce the frequency in computing error in each frame simultaneously. Experiments demonstrate that the algorithm reduces the calculation effectively, and represents the large-scale terrain very well in real time.

IEEE International Conference on Rehabilitation Robotics (ICORR)

作者： Jiting Li Ruoyin Zheng Yuru Zhang Jianchu Yao State Key Laboratory of Virtual Reality Technology and Systems Beihang University Beijing China Department of Engineering College of Technology and Computer Science East Carolina University Greenville NC USA

This paper presents an interactive exoskeleton device for hand rehabilitation, iHandRehab, which aims to satisfy the essential requirements for both active and passive rehabilitation motions. iHandRehab is comprised of exoskeletons for the thumb and index finger. These exoskeletons are driven by distant actuation modules through a cable/sheath transmission mechanism. The exoskeleton for each finger has 4 degrees of freedom (DOF), providing independent control for all finger joints. The joint motion is accomplished by a parallelogram mechanism so that the joints of the device and their corresponding finger joints have the same angular displacement when they rotate. Thanks to this design, the joint angles can be measured by sensors real time and high level motion control is therefore made very simple without the need of complicated kinematics. The paper also discusses important issues when the device is used by different patients, including its adjustable joint range of motion (ROM) and adjustable range of phalanx length (ROPL). Experimentally collected data show that the achieved ROM is close to that of a healthy hand and the ROPL covers the size of a typical hand, satisfying the size need of regular hand rehabilitation. In order to evaluate the performance when it works as a haptic device in active mode, the equivalent moment of inertia (MOI) of the device is calculated. The results prove that the device has low inertia which is critical in order to obtain good backdrivability. Experimental analysis shows that the influence of friction accounts for a large portion of the driving torque and warrants future investigation.

IEEE International Conference on Spatial Data Mining and Geographical Knowledge Services (ICSDM)

作者： Sheng Liu Genlin Ji Wenjun Li Key Laboratory of Virtual Geographic Environment Ministry of Education Nanjing Normal University Jiangsu China School of Computer Science and Technology Nanjing Normal University Jiangsu China

Spatial lines are common in various spatial applications such as GIS (Geographical Information System). Topological relationship is one of important properties between spatial lines. Neglecting disjoint relations and adjacent relations between spatial lines, in this paper we focus on intersection relations. Time series of spatial lines intersection relations record each spatial line intersection relations at each time. The changes of intersection relationship are caused by deformations (translation, rotation, and length of spatial lines) and increasing or decreasing of the number of spatial lines neighbours. We propose a similarity measure for time series of spatial lines topological relations. By this measure, we can cluster these spatial lines on time series of their intersection relations.

World Haptics Conference

作者： Zhixiang Wang Dangxiao Wang Yuru Zhang Ming C. Lin State Key Laboratory of Virtual Reality Technology and Systems Beihang University Beijing China Department of Computer Science North Carolina State University Chapel Hill USA

virtual coupling is commonly used to maintain stability of penalty-based haptic rendering. However, due to dozens of design parameters involved in the dynamics and force model, to increase transparency while maintaining stability using virtual coupling remains a challenge for 6-Degree-of-Freedom (DOF) haptic rendering. Using an equivalent-angle analysis, we transform 3-DOF rotation into 1-DOF rotation, thereby transforming the 6-DOF dynamics into six 1-DOF dynamics. For each 1-DOF dynamics, a damped vibration model is proposed to analyze the computation of the `graphic tool'. The equilibrium position/angle is defined to analyze the convergence of numerical integration. With this approach, we can improve the transparency of 6-DOF haptic rendering in both free space and constraint space by experimentally determining only two parameters: the integration time step and the number of integrations in each simulation loop. Using this method, we can improve the coupling stiffness to fully exploit the display capability of the haptic device and maintain the stability of the haptic rendering.

随着三维应用的普及,三维模型大量产生并广泛传播。由于三维模型广泛应用于计算机辅助设计、三维游戏、电影特效制作等诸多领域,已经形成了大量的三维模型数据库。三维模型语义标注的目的是给出描述其语义的标注词,是三维模型管理和基于文本的三维检索的关键技术。针对互联网大量存在的弱标签三维模型现状,提出一种基于弱标签的三维模型语义标注方法LPMLL,首先,采用半监督学习方法进行标签传播,得到标注词置信度,达到提升训练集的目的。然后,采用一种基于最大后验概率准则的方法进行多标签学习,得到最终标注词。实验数据表明了该方法的有效性。

In this paper, we propose the Interval-valued Matrix Factorization (IMF) framework. Matrix Factorization (MF) is a fundamental building block of data mining. MF techniques, such as Nonnegative Matrix Factorization (NMF) and Probabilistic Matrix Factorization (PMF), are widely used in applications of data mining. For example, NMF has shown its advantage in Face Analysis (FA) while PMF has been successfully applied to Collaborative Filtering (CF). In this paper, we analyze the data approximation in FA as well as CF applications and construct interval-valued matrices to capture these approximation phenomenons. We adapt basic NMF and PMF models to the interval-valued matrices and propose Interval-valued NMF (I-NMF) as well as Interval-valued PMF (I-PMF). We conduct extensive experiments to show that proposed I-NMF and I-PMF significantly outperform their single-valued counterparts in FA and CF applications. © 2010 IEEE.

Trace-driven simulation methodology is the most widely used method to evaluate the design of future computer memory architecture. Since this methodology demands large amounts of storage and computer time, there is a growing need for simulation methodologies to determine the memory system requirements of emerging workloads in a reasonable amount of time. Several techniques have been proposed to reduce the space that store memory reference and improve the performance of sequential trace-driven simulation. This paper presents the use of binary instrumentation as the memory reference generator and parallel simulation technique that based on the generic graphics processing unit (GPU). One way to achieve fast parallel simulation is to simulate the independent sets of a cache concurrently on different compute resource, but results show that this method is not efficient because of a high correlation of the activity between different sets. To put parallelism to effective use, we show that a multi-configuration simulation in single pass method gains 2.44x performance improvement compared to traditional sequential algorithm. © 2010 SCS.

In order to effectively deal with large-scale attacks on computer networks, computer Network Defense (CND) policy refinement based on descriptive language is wildly used. However, it's very difficult to figure out the semantic discrepancies between the measures and the predefined policy after the calculation with symbols by computers. A new method is presented to solve the discordance of semantic between the measures and the predefined policy automatically. Based on the establishment of the ontology of CND policy and measure (CNDPM), the CND policy and measure semantic similarity analysis model (CNDPMSSAM) is established, and then the termination of the two main components of CNDPMSSAM are proofed by the putdown automaton, and the prototype system of CNDPMSSAM is implemented. At last, we validate the validity of this method on analyzing semantic similarity of transferring from computer Network Defense Policy Specification Language (CNDPSL) to Defense Measure Description Language (DMDL) with experiments. © 2010 IEEE.

Peer-to-peer (P2P) Botnets, which are more resilient and robust than centralized botnets, have emerged as the peer-to-peer technology evolves. Better understanding of this new phenomenon will help researchers develop detection and mitigation methods. Most of existing work is case study of typical P2P botnets. In this paper, we focus on systematically analyzing structures of P2P botnets. We propose a descriptive model of P2P botnet structures, which consists of features of P2P bot, definitions of structures, and structural properties. Firstly, we detail two key functionalities of P2P bot, command-and-control (C&C) functionality and peer-to-peer (P2P) functionality, and give several features of P2P bot. And then, we define two structures of P2P botnets: C&C structure and P2P structure. To characterize these structures, we propose several properties and corresponding quantitative methods. Finally, we conduct experiments to verify our results. © 2010 IEEE.
