Research on System Architecture and Interfaces in Heterogeneous Network Platform
Authors: Fei Ma, Wen-an Zhou, Lu Liu, Jun-de Song
Venue: Proceedings of the 2009 Asia-Pacific Conference on Information Processing - Volume 01 (2009)

The paper proposes an architecture for heterogeneous network platform based on adaptation layer according to service capability requirements and characteristics of modern service industry. In order to shield the diversity of heterogeneous networks to provide open interfaces in the adaptation layer, an abstract method of service capability is proposed to get a set of SCF components and sub-platforms. The basic service capabilities can be also integrated to generate new services by the service integration method. Some interfaces and service applications illustrate that the abstract method and interfaces are reasonably effective on the platform for the applications of modern service industry.
Indexing Large Visual Vocabulary by Randomized Dimensions Hashing for High Quantization Accuracy: Improving the Object Retrieval Quality
Authors: Heng Yang, Qing Wang, Zhoucan He
Venue: Proceedings of the 13th International Conference on Computer Analysis of Images and Patterns (2009)

The bag-of-visual-words approach, inspired by text retrieval methods, has proven successful in achieving high performance in object retrieval on large-scale databases. A key step of these methods is the quantization stage which maps the high-dimensional image feature vectors to discriminatory visual words. In this paper, we consider the quantization step as the nearest neighbor search in large visual vocabulary, and thus proposed a randomized dimensions hashing (RDH) algorithm to efficiently index and search the large visual vocabulary. The experimental results have demonstrated that the proposed algorithm can effectively increase the quantization accuracy compared to the vocabulary tree based methods which represent the state-of-the-art. Consequently, the object retrieval performance can be significantly improved by our method in the large-scale database.
An Efficient Data Dissemination Scheme for Sensor Networks
Authors: Po-Jen Chuang, Bo-Yi Li
Venue: Proceedings of the 9th International Conference on Algorithms and Architectures for Parallel Processing (2009)

Disseminating data from sources to sinks is a very important application in sensor networks. This paper presents a new data dissemination scheme which uses the concept of the Fermat Point to construct a dissemination tree from one source (the root) to multiple sinks (the leaves). By sending data along the dissemination tree, the new scheme can conserve transmission energy, avoid collision and as a result reduce transmission delay. When sinks move, the proposed scheme can also adjust the dissemination tree topology to achieve high performance. Simulation runs are conducted to evaluate the performance of our new scheme and other related schemes including the Two-Tier Data Dissemination (TTDD) and the DElay-constrained minimum-Energy Dissemination (DEED). The collected result shows that our scheme can send data from a source to several sinks in more efficient way and as a result save more transmission energy and time than the other two schemes.
Stereo Visual Odometry for Mobile Robots on Uneven Terrain
Authors: Stefan Ericson, Björn Astrand
Venue: Proceedings of the Advances in Electrical and Electronics Engineering - IAENG Special Edition of the World Congress on Engineering and Computer Science 2008 (2008)

In this paper we present a stereo visual odometry system for mobile robots that is not sensitive to uneven terrain. Two cameras is mounted perpendicular to the ground and height and traveled distance are calculated using normalized cross correlation. A method for evaluating the system is developed, where flower boxes containing representative surfaces are placed in a metal-working lathe. The cameras are mounted on the carriage which can be positioned manually with 0.1 mm accuracy. Images are captured every 10 mm over 700 mm. The tests are performed on eight different surfaces representing real world situations. The resulting error is less than 0.6% of traveled distance on surfaces where the maximum height variation is measured to 96 mm. The variance is measured for eight test runs, total 5.6 m, to 0.040 mm. This accuracy is sufficient for crop-scale agricultural operations.
Wavelet BEM on molecular surfaces: parametrization and implementation
Authors: Helmut Harbrecht, Maharavo Randrianarivony
Venue: Computing (2009)

The present paper is dedicated to the rapid solution of boundary integral equations arising from solvation continuum models. We apply a fully discrete wavelet Galerkin scheme for the computation of the apparent surface charge on van der Waals or solvent accessible surfaces. The molecular surface is described in parametric form as a set of four-sided spherical patches. Each patch is exactly represented as rational B&#x00e9;zier surface. Numerical results are reported to illustrate the approach.
Fast Prototype Based Noise Reduction
Authors: Kajsa Tibell, Hagen Spies, Magnus Borga
Venue: Proceedings of the 16th Scandinavian Conference on Image Analysis (2009)

This paper introduces a novel method for noise reduction in medical images based on concepts of the Non-Local Means algorithm. The main objective has been to develop a method that optimizes the processing speed to achieve practical applicability without compromising the quality of the resulting images. A database consisting of prototypes, composed of pixel neighborhoods originating from several images of similar motif, has been created. By using a dedicated data structure, here Locality Sensitive Hashing (LSH), fast access to appropriate prototypes is granted. Experimental results show that the proposed method can be used to provide noise reduction with high quality results in a fraction of the time required by the Non-local Means algorithm.

Authors: Tong Zhen, Yuhua Zhu, Qiuwen Zhang
Venue: Proceedings of the 2009 International Conference on Environmental Science and Information Application Technology - Volume 02 (2009)

In the supply chain, a warehouse is an essential component for linking the chain partners. It is necessary to allocate warehouse resources efficiently and effectively to enhance the productivity and reduce the operation costs of the warehouse. Therefore, warehouse management systems (WMSs) have been developed for handling warehouse resources and monitoring warehouse operations. In this paper, a RFID technology is adopted to facilitate the collection and sharing of data in a warehouse. Tests are performed for evaluating the reading performance of both the active and passive RFID apparatus. With the help of the testing results, the efficient radio frequency cover ranges of the readers are examined for formulating a radio frequency identification case-based logistics resource management system (R-LRMS). The successful case example proved the feasibility of R-LRMS in real working practice.
The Dynamic Element Matching Method for Sigma-Delta D/A and A/D Converters
Authors: Feng Hui, Yu Zeqi
Venue: Proceedings of the 2009 International Forum on Information Technology and Applications - Volume 01 (2009)

When multi-bit quantizer is used in sigma-delta D/A and A/D converters, nonlinear error is produced in multi-bit switched capacitor DAC because of capacity mismatch. A method used to remove this nonlinear error is introduced in this paper. This method encodes the output of quantizer, and then the output can switch the switched capacitors in multi-bit switched capacitor DAC randomly, introducing random noise to smooth the nonlinear distortion. But the introduced random noise will raise the level of background noise in signal bandwidth. Considering that, the technique of noise-shaping is used in this method to put the noise in signal bandwidth out of signal bandwidth, expecting the improvement of the converters' performance. A design example is presented in this paper, and the simulation result of the design indicates this method can remove the nonlinear error completely.
Optimal Neural Network Modeling Method Based on Data Noise Information
Authors: Yanpo Song, Xiaoqi Peng, Ying Tang
Venue: Proceedings of the 2009 International Conference on Measuring Technology and Mechatronics Automation - Volume 02 (2009)

Aiming at some problems such as “over-fit” with ANN modeling, a new type of combined neural network and corresponding optimal modeling method are proposed in this paper. By this method, expectation error (namely, possible minimum error) is firstly estimated according to data quality; then, optimize network structure and choose optimal training result according to the difference between actual error and expectation error. To evaluate objectively the performance of model, a new evaluation index named error average power (EAP) is introduced. Simulation experimental results show that the methods mentioned above can work with good performance.

Reverse logistics is the means driving economic growth, and third-party reverse logistics (3PRL) is the important carrier to realize reverse logistics. So, the analysis on 3PRL and its provider selection is important. All of these third-party companies would benefit from a framework for decision making to determine if entry into this market is feasible for them. This paper firstly present the conception of reverse logistics. After that, the paper creates the business processes on third-party reverse logistics, and analyzed the advantages of third-party reverse logistics. On the basis of this, an recycling programs of third-party reverse logistics is built, and an example demonstrates the model's efficiency.

Authors: Erik A. van Doorn, Nicky D. van Foreest, Alexander I. Zeifman
Venue: Journal of Computational and Applied Mathematics (2009)

We establish some representations for the smallest and largest zeros of orthogonal polynomials in terms of the parameters in the three-terms recurrence relation. As a corollary we obtain representations for the endpoints of the true interval of orthogonality. Implications of these results for the decay parameter of a birth-death process (with killing) are displayed.
Structural Similarity Based Information Hiding
Authors: Xinhong Zhang, Yuli Xu, Fan Zhang
Venue: Proceedings of the 2009 IITA International Conference on Control, Automation and Systems Engineering (case 2009) (2009)

An information hiding algorithm based on the structural similarity is presented. In the proposed algorithm, given an original image, and hidden some information in the original image without taking into account the HVS (Human Visual System), then get a stego image. Two images are divided into some sub-blocks with the same size. Then the structure similarity of the corresponding block is calculated. If the structural similarity is greater than a threshold, the sub-block information from the stego image is extracted, and hidden this information into the corresponding block of original image.

From Formal Specification of Code Mobility to Design and Implementation: An UML-Based Mobile Agent Approach
Authors: Amelia Badica, Costin Badica
Venue: Proceedings of the 2008 10th International Symposium on Symbolic and Numeric Algorithms for Scientific Computing (2008)

The contribution of this paper is to propose a simple approach for the design and implementation of code mobility using mobile software agents. The approach is demonstrated by its application to standard code mobility paradigms. We start from existing formalizations ofcode mobility paradigms and show how they can be used to derive standard UML sequence diagrams that describe agent interactions andmigration. Then we show how these diagrams can guide a prototype JADE-based implementation of the client-server code mobility paradigm.
Cost-sensitive learning based on Bregman divergences
Authors: Raúl Santos-Rodríguez, Alicia Guerrero-Curieses, Rocío Alaiz-Rodríguez, Jesús Cid-Sueiro
Venue: Machine Learning (2009)

This paper analyzes the application of a particular class of Bregman divergences to design cost-sensitive classifiers for multiclass problems. We show that these divergence measures can be used to estimate posterior probabilities with maximal accuracy for the probability values that are close to the decision boundaries. Asymptotically, the proposed divergence measures provide classifiers minimizing the sum of decision costs in non-separable problems, and maximizing a margin in separable MAP problems.
Multicausality
Authors: John N. Warfield
Venue: Journal of Integrated Design Process Science (2008)

Many explanations of events treat them as unicausal. Most of the major issues of today are multicausal. Multicausal events raise issues of direct and indirect causality, and issues related to cognition. These, in turn, involve structural considerations that cannot be properly dealt with in limited mass media. By attempting to deal with such issues in mass media, congressional debates debase the debaters. The economics crises afflicting the world today illustrate the failure of leaders to apply multicausal analysis to develop a proper understanding of the issues. But more importantly, there is no recognized leadership in the design of economic systems, which is the more fundamental reason why systems have been placed at risk. And still more fundamental is the lack of adequate systems education in those educational institutions that have produced those in positions of economic power today.

Authors: Xinping Liu, Halin Zhao, Yuhui He, Xueyong Zhao, Tonghui Zhang, Yuqiang Li
Venue: Proceedings of the 2009 International Conference on Environmental Science and Information Application Technology - Volume 02 (2009)

A laboratory experiment was conducted in May 2006 to measure water diffusivity (Dθ) of sandy soil of different particle sizes. The method of cobalt chloride test paper (CCTP) was made to observe moving position of wetting front. Results showed that the rate of wetting front advancement (RWFA) is in the order: 0.50-0.25 mm soil＞ 0.25-0.10 mm soil＞ undisturbed soil＞ the soil of less than 0.10 mm. The relationship between infiltration distance and the RWFA was expressed as a power function. With decrease in the sand particle sizes, Dθ was decreased gradually. The Dθ change was most obvious in the soil of 0.50-0.25 mm, the least obvious one was the soil of less than 0.10mm. There existed significant correlation between Dθ and soil water content which met an exponential curve and was in accordance with the empirical equation. As a new attempt, CCTP was reliable to measure the position of wetting front and decrease the subjective error of visual method.

Authors: Zhibin Jiang, Chao Xie
Venue: Proceedings of the 2009 International Conference on Measuring Technology and Mechatronics Automation - Volume 03 (2009)

A primary delay is the deviation from a scheduled process time caused by disruption within the process. Delay is controlled by timetable and shows the characters of random occurrence. Rail transit system is a complex system which is dynamic, nonlinear, self-adaptive, random-occurrence and schedule-controllability. The Multi-agent method enlarges the range of computer applying in rail system. This paper brings forward the delay simulation model which bases on Multi-agent, and discusses the definition, characters, applying of Multi-agent. Emphasizes the frame of delay simulation system basing on Multi-agent, and builds a Multi-agent delay simulation model which bases upon the train agent-gather, adjusted strategy agent-gather, and simulation environment. By the end, the model was illustrated by a sample of rail transit line 3 and line4 in Shanghai.
Integrated videos and maps for driving directions
Authors: Billy Chen, Boris Neubert, Eyal Ofek, Oliver Deussen, Michael F. Cohen
Venue: Proceedings of the 22nd annual ACM symposium on User interface software and technology (2009)

While onboard navigation systems are gaining in importance, maps are still the medium of choice for laying out a route to a destination and for way finding. However, even with a map, one is almost always more comfortable navigating a route the second time due to the visual memory of the route. To make the first time navigating a route feel more familiar, we present a system that integrates a map with a video automatically constructed from panoramic imagery captured at close intervals along the route. The routing information is used to create a variable speed video depicting the route. During playback of the video, the frame and field of view are dynamically modulated to highlight salient features along the route and connect them back to the map. A user interface is demonstrated to allow exploration of the combined map, video, and textual driving directions. We discuss the construction of the hybrid map and video interface. Finally, we report the results of a study that provides evidence of the effectiveness of such a system for route following.
