This paper deals with two relatively less well studied problems in Textual CBR, namely visualizing and evaluating complexity of textual case bases. The first is useful in case base maintenance, the second in making informed choices regarding case base representation and tuning of parameters for the TCBR system, and also for explaining the behaviour of different retrieval/classification techniques over diverse case bases. We present an approach to visualize textual case bases by "stacking" similar cases and features close to each other in an image derived from the case-feature matrix. We propose a complexity measure called GAME that exploits regularities in stacked images to evaluate the alignment between problem and solution components of cases. GAME class , a counterpart of GAME in classification domains, shows a strong correspondence with accuracies reported by standard classifiers over classification tasks of varying complexity. © Springer-Verlag Berlin Heidelberg 2008.

IEEE International Conference on Micro Electro Mechanical systems

作者： N. Ghalichechian M. McCarthy M. I. Beyaz R. Ghodssi MEMS Sensors and Actuators Lab (MSAL) Department of Electrical and Computer Engineering Institute for Systems Research University of Maryland College Park MD USA

We report, for the first time, the measurement and modeling of friction in both linear and rotary micromotors supported on microball bearings using transient-response characterization. For the linear micromotor the friction force of 0.33 mN was measured at the velocity of 7 -10 mm/s and normal force of 20 mN. The average coefficient of friction (mu), defined as the ratio of frictional to normal force, and the minimum dashpot coefficient (B), defined as the ratio of frictional force to rolling velocity, were extracted to be 0.02 and 4 x 10 -2 kg/s , respectively, for the linear device. The average friction torque, mu, and B for the rotary micromotor were measured to be 5.7 muN.m, 0.02, and 2.6 x 10 -4 kg/s, respectively, with the tip velocity of 144 mm/s and normal loading of 2 mN. These results enable understanding of frictional forces and their dependencies on operating velocities and normal loadings in microball-bearing-supported micromachines.

作者： Zhichun Yang Yiguang Hong Key Laboratory of Systems and Control Institute of Systems Science Chinese Academy of Sciences Beijing 100080 China Chongqing Key Lab of Operations Research and System Engineering Department of Mathematics and Computer Science Chongqing Normal University Chongqing 400047 China

In this paper, a class of hybrid impulsive systems with time delays and stochastic effects are considered. We obtain some criteria on the global exponential stability in mean square for the impulsive stochastic delayed systems. To do this, differential inequalities and ℒ-operator inequalities are developed. An example is given to illustrate the effectiveness of our results.

2008 IEEE International Conference on Automation Science and engineering (CASE 2008), vol.1

作者： Junwen Wang Jingshan Li Jorge Arinez Stephan Biller Ningjian Huang Department of Electrical and Computer Engineering and Center for Manufacturing University of Kentucky Lexington KY USA Manufacturing Systems Research Laboratory General Motors Research and Development Center Warren MI USA Manufacturing Systems Research Lab General Motors Research & Development Center Warren MI USA

In this paper, we present an analytical method to evaluate the quality performance of flexible manufacturing systems with batch operations. Many flexible manufacturing systems implement batch production to shorten changeover time, reduce cost, and improve quality. In such systems, different types of products are process in batches where all products in each batch have the same type. The change of product type only occurs after the last job in a batch is processed. A closed formula to quantify the probability of producing a good part is derived and structural properties to address the appropriate sequence of products are presented.

We investigate the impact of node capture attacks on the confidentiality and integrity of network traffic. We map the compromise of network traffic to the flow of current through an electric circuit and propose a metric for quantifying the vulnerability of the traffic using the circuit mapping. We compute the vulnerability metric as a function of the routing and the cryptographic protocols used to secure the network traffic. We formulate the minimum cost node capture attack problem as a nonlinear integer programming problem. Due to the NP-hardness of the minimization problem, we provide a greedy heuristic that approximates the minimum cost attack. We provide examples of node capture attacks using our vulnerability metric and show that the adversary can expend significantly less resources to compromise target traffic by exploiting information leakage from the routing and cryptographic protocols.

The field of Unmanned Aerial Vehicles (UAV) has gained great significance in the R&D activities of several institutions, and numerous realizations have been constructed. Controlling the movement of a UAV is one of the most significant tasks in the hierarchical control system that should be realized in order to successfully manage UAVs in several missions. Precise control of the movement requires accurate mathematical models of the aircraft that correspond to the several control schemes that are intended to apply, including linearised, LPV, and nonlinear ones. The source of mathematical models includes the physical model constructed on the basis of the Newtonian equations and the rules of aerodynamics, as well as the use of empirical observations, measurements. The methodology of system identification offers the tools that can be used to manage this field. The systems and Control laboratory of the computer and Automation research Institute in cooperation with University of Minnesota and Budapest University of Technology and Economics has built - as a part of a more general framework established to solve complex UAV control problems - small UAVs, equipped with on-board sensors and embedded computer with the purpose of obtaining an adequate test platform for the aircraft experiments. Based on on-board measurements acquired during the flight tests performed with the UAVs, the opportunity has been given to test several system identification approaches corresponding to the control tasks to be solved. This paper gives an outline of the system identification and modelling methods that have successfully been applied, and also analyzes the problems encountered in the data-acquisition - signal processing - computing chain.

Existing digital rights management (abbr. DRM) approaches lack a flexible fine-grained digital rights transfer policy, also could not guarantee the trustworthy distribution and enforcement of the transferable rights policy by using DRM agent. First, descriptions of extensible ODRL-based rights transfer policy were presented to complete OMA REL. Then, we introduced a remote attestation mechanism among entities, such as RI and DRM agent, based on trusted computing platform in order to implement trusted distribution and enforcement of the policy, also mainly proposed trustworthy distribution protocols of the rights object and transfer, as well as a trusted policy enforcement protocol. Final, the approach is made comparison with existing DRM schemes as to several functionality aspects on transferable rights granularity, restricted sharing, temporal limitation, trust of DRM agent. A conclusion is drawn that the proposed scheme is not restricted within local domain environment, and accomplishes fine-grained rights transfer and contents sharing between users without direct participations of rights issuer or local domain manager.

We discuss the electrical resistivity and thermal stability of smooth thin silver (Ag) films characterized by significantly lower root mean square (RMS) surface roughness, peak-to-valley height distribution, and grain-size distribution. The smooth film was prepared by using a very thin (~1-2 nm) nucleation layer of evaporated germanium (Ge) prior to Ag evaporation. The sheet resistance of the rough silver (10nm Ag) film is RAg-rough ~51 Ω/sq compared to the smooth silver (10nm Ag/2nm Ge) film with R Ag-smooth ~22 Ω/sq. The smooth Ag is also shown to be thermally more stable for temperatures less than 120C. © 2008 IEEE.
