A Block-Based Watermarking Method Using Wavelet Coefficient Quantization
Authors: Wei-Hung Lin, Yuh-Rau Wang, Shi-Jinn Horng
Venue: Proceedings of the 9th International Conference on Algorithms and Architectures for Parallel Processing (2009)

A watermarking technique is referred to as blind if the original image is not needed for extraction. In this paper, a blind watermarking method based on discrete wavelet transform (DWT) using maximum wavelet coefficient quantization is proposed. The wavelet coefficients are grouped into different block size with each block being randomly selected from different subbands. The watermark is embedded in the local maximum coefficient which can effectively resist attacks. Experimental results show that the proposed method is quite robust under either non-geometry or geometry attacks.
Travel Time Estimation for Recurrent Jammed Flow on Shanghai North-South Expressway
Authors: Peng Chen, Keping Li, Jian Sun
Venue: Proceedings of the 2009 International Conference on Measuring Technology and Mechatronics Automation - Volume 03 (2009)

The conventional point-detector based method for travel time estimation does not consider the impact of future downstream traffic conditions and may deviate significantly from real travel times during congestion. Though many newly arising algorithms have been developed, it is difficult for them to be applied in real situation. This paper proposes a novel and easy-to-implement method of travel time estimation using effective capacity at the bottlenecks of expressway based on actual data during recurrent congestion periods. Then the method is applied to Shanghai North-south expressway in the microscopic simulation program VISSIM. The experiment results show the accuracy is satisfying in 5-minute intervals.

Authors: N. I. Golovko, V. V. Katrakhov, D. E. Ryzhkov
Venue: Automation and Remote Control (2009)

We consider a single-server queueing system (QS) with finite memory and exponential service with parameter µ. The QS is fed by a doubly stochastic Poisson flow whose intensity ¿(t) is a jump process. We propose a matrix and a functional-analytical method to study stationary and nonstationary characteristics of the QS; we also prove existence and uniqueness of a stationary regime and stabilization of a nonstationary regime of the QS. Results of numerical analysis are discussed.

PageRank: Splitting Homogeneous Singular Linear Systems of Index One
Authors: Douglas V. Jager, Jeremy T. Bradley
Venue: Proceedings of the 2nd International Conference on Theory of Information Retrieval: Advances in Information Retrieval Theory (2009)

The PageRank algorithm is used today within web information retrieval to provide a content-neutral ranking metric over web pages. It employs power method iterations to solve for the steady-state vector of a DTMC. The defining one-step probability transition matrix of this DTMC is derived from the hyperlink structure of the web and a model of web surfing behaviour which accounts for user bookmarks and memorised URLs.In this paper we look to provide a more accessible, more broadly applicable explanation than has been given in the literature of how to make PageRank calculation more tractable through removal of the dangling-page matrix. This allows web pages without outgoing links to be removed before we employ power method iterations. It also allows decomposition of the problem according to irreducible subcomponents of the original transition matrix. Our explanation also covers a PageRank extension to accommodate TrustRank. In setting out our alternative explanation, we introduce and apply a general linear algebraic theorem which allows us to map homogeneous singular linear systems of index one to inhomogeneous non-singular linear systems with a shared solution vector. As an aside, we show in this paper that irreducibility is not required for PageRank to be well-defined.

Early Fault Identification of Aircraft and Self-Recovery Monitoring of Fault
Authors: Zhongsheng Wang, Shiwe Ma
Venue: Proceedings of the 2009 International Conference on Measuring Technology and Mechatronics Automation - Volume 01 (2009)

In order to increase robustness of the aircraft and to solve the problem of lacking fault samples in fault diagnosis and the difficulty in identifying early weak fault, we proposed a new method for identifying the early fault of the aircraft and it can do self-recovery monitoring of the fault. Our method is based on the analysis of the characteristics of early fault of the aircraft, and it combined the SVM (support vector machine) with the stochastic resonance theory and the wavelet packet decomposition. First, we zoom the early fault feature signals by using the stochastic resonance theory. Second, we extract feature vectors of the early fault by using the multi-resolution analysis of the wavelet packet. Third, we input the feature vectors to a fault classifier, which can be used to identify the early fault of the aircraft quickly and do self-recovery monitor of fault. In this paper, feature of early fault on aircraft, the zoom of early fault characteristics, the extraction method of early fault feature, the construction of multi-fault classifier and way of fault self-recovery monitoring are studied. Results show that our method can effectively identify the early fault of aircraft, especially for identifying of fault with small samples, and it can carry on monitoring of fault self-recovery.

Authors: Sun Xingbin, Zuo Jinlong
Venue: Proceedings of the 2009 IITA International Conference on Control, Automation and Systems Engineering (case 2009) (2009)

Based on the practical engineering and aimed at the food wastewater, a series experiments were conducted to investigate parameter on the effluents qualities by submerged membrane bioreactor (SMBR). A better removal performance in a SMBR could be achieved to treat food wastewater. The removal efficiencies in MBR were obtained worked with HRT at 10h, DO at 2.5mg/L and pH at 7.8, respectively. During the whole experimental period, the SMBR effluent COD and color varied in the range 35-50mg/L and 20-30 degrees, respectively. In this way, the effluent met the national first grade discharge standard steadily and avoided the nonsynchronous degradation of COD and color. The membrane fouling was investigated by analysis of the images and the SEM. The chemical cleaning of the membrane with a 5% solution of HCl can removal most of the fouling pollutants. When the membrane was regenerated with a 1% solution of NaOH, membrane fouling was diminished. After treatment with both two cleaning agents, the membrane maintained its flux within a range of 0.08 to 0.09 m3/ (m2/d).

Venue: Proceedings of the 2009 International Conference on Measuring Technology and Mechatronics Automation - Volume 03 (2009)

Deep-sea Flange Connection Tooling (DFCT) is a special kind of tools to complete the flange connection of deepwater pipeline, which will greatly enhance the development of China's deepwater Tie-ins technology. In this paper, through analyzing the sealing theory of flange connection, paper has presented general structure scheme of tool, including mechanical structure and hydraulic control system, and the proposed scheme is feasible by theoretical analysis. Through checking the key parts’ strength of the DFCT by using the finite element method and doing research on the system multi-body dynamics simulation studies, the results show that the mechanical structure is reasonable. Thereby, paper provides a reference for the further development of the DFCT.
A Data Fusion Algorithm for Marine Radar Tracking
Authors: Ying Shijun, Chen Jinbiao, Shi Chaojian
Venue: Proceedings of the 2009 WRI Global Congress on Intelligent Systems - Volume 01 (2009)

Automatic Radar Plotting Aids (ARPA) and Automatic Identification System (AIS) are the most important navigational systems on board. ARPA is considered as the primary anti-collision system, but its detecting ability, tracking accuracy and reliability are affected badly under the rough environmental weather condition. AIS provide steady and continuous navigation data come from GPS or DGPS with higher precision. In this paper, a data fusion algorithm has been developed for ARPA with AIS position data to improve its tracking accuracy and reliability. The proposed algorithm was experimented on a navigational radar simulator and a pc based platform programmed with VC++. The simulating results show that this method can effectively improve the accuracy and reliability of tracking.
Czech Spontaneous Speech Collection and Annotation: The Database of Technical Lectures
Authors: Josef Rajnoha, Petr Pollák
Venue: Cross-Modal Analysis of Speech, Gestures, Gaze and Facial Expressions: COST Action 2102 International Conference Prague, Czech Republic, October 15-18, 2008 Revised Selected and Invited Papers (2009)

Applying speech recognition into real working systems, spontaneous speech recognition has increasing importance. For the development purposes of such applications, the need of spontaneous speech database is evident both for general design or training and testing of such systems. This paper describes the collection of Czech spontaneous data recorded within technical lectures. It is supposed to be used as a material for the analysis of particular phenomena which appear within spontaneous speech but also as an extension material for training of spontaneous speech recognizers. Mainly the presence of spontaneous speech phenomena such as higher rate of non-speech events, changes in pronunciation, or sentence irregularities, should be the most important contribution of the collected database for the training purposes in comparison to the usage of available read speech databases only. Speech signals are captured in two different channels with slightly different quality and about 14 hours of speech from 15 different speakers are currently collected and annotated. The first analyses of spontaneous speech related effects in the collected data have been performed and the comparison with read speech databases is presented.
Predicting the Usefulness of Collection Enrichment for Enterprise Search
Authors: Jie Peng, Ben He, Iadh Ounis
Venue: Proceedings of the 2nd International Conference on Theory of Information Retrieval: Advances in Information Retrieval Theory (2009)

Query Expansion (QE) often improves the retrieval performance of an Information Retrieval (IR) system. However, as enterprise intranets are often sparse in nature, with limited use of alternative lexical representations between authors, it can be advantageous to use Collection Enrichment (CE) to gather higher quality pseudo-feedback documents. In this paper, we propose the use of query performance predictors to selectively apply CE on a per-query basis. We thoroughly evaluate our approach on the CERC standard test collection and its corresponding topic sets from the TREC 2007 2008 Enterprise track document search tasks. We experiment with 3 different external resources and 3 different query performance predictors. Our experimental results demonstrate that our proposed approach leads to a significant improvement in retrieval performance.

Lessons learned from an interaction-kiosk for open selection of input devices of a gaming application
Authors: Andreas Lorenz, Ferry Pramudianto, Andreas Zimmermann
Venue: Proceedings of the 11th International Conference on Human-Computer Interaction with Mobile Devices and Services (2009)

Traditional computer applications understand mouse and keyboard input for controlling the behavior of the system. Depending on the goal, task and situation of the user, other input devices can be more appropriate to meet the user's personal attributes. To demonstrate the value of enabling the user to select an input device according to personal preferences, this work combines a device independent control mechanism with a game application. The paper illustrates seven lessons learned from observing users in playing the game with six devices that feature different modalities.
Competing Retailers and Inventory: An Empirical Investigation of General Motors' Dealerships in Isolated U.S. Markets
Authors: Marcelo Olivares, Gérard P. Cachon
Venue: Management Science (2009)

We study the following question: How does competition influence the inventory holdings of General Motors' dealerships operating in isolated U.S. markets? We wish to disentangle two mechanisms by which local competition influences a dealer's inventory: (1) the entry or exit of a competitor can change a retailer's demand (a sales effect); and (2) the entry or exit of a competitor can change the amount of buffer stock a retailer holds, which influences the probability that a consumer finds a desired product in stock (a service-level effect). Theory is clear on the sales effect---an increase in sales leads to an increase in inventory (albeit a less than proportional increase). However, theoretical models of inventory competition are ambiguous on the expected sign of the service-level effect. Via a Web crawler, we obtained data on inventory and sales for more than 200 dealerships over a six-month period. Using cross-sectional variation, we estimated the effect of the number and type of local competitors on inventory holdings. We used several instrumental variables to control for the endogeneity of market entry decisions. Our results suggest that the service-level effect is strong, nonlinear, and positive. Hence, we observe that dealers carry more inventory (controlling for sales) when they face additional competition.

On meeting lifetime goals and providing constant application quality
Authors: Andreas Lachenmann, Klaus Herrmann, Kurt Rothermel, Pedro José Marrón
Venue: ACM Transactions on Sensor Networks (TOSN) (2009)

Most work in sensor networks tries to maximize network lifetime. However, for many applications the required lifetime is known in advance. Therefore, application quality should rather be maximized for that given time.Levels, the approach presented in this article, is a programming abstraction for energy-aware sensor network applications that helps to meet such a user-defined lifetime goal by deactivating optional functionality. With this programming abstraction, the application developer defines so-called energy levels. Functionality in energy levels is deactivated if the required lifetime cannot be met otherwise. The runtime system uses data about the energy consumption of different levels to compute an optimal level assignment that maximizes each node's quality for the time remaining. As described in this paper, Levels includes a completely distributed coordination algorithm that balances energy level assignments and keeps the application quality of the network roughly constant over time. In this approach, each node computes its schedule based on those of its neighbors. As the evaluation shows, applications using Levels can accurately meet given lifetime goals with only small fluctuations in application quality. In addition, the runtime overhead both for computation and for communication is negligible.

Authors: Peng Wu, Yuehui Chen, Tao Xu, Haokui Tang
Venue: Proceedings of the 2009 International Conference on Computational Intelligence and Natural Computing - Volume 01 (2009)

In this paper, a new automatic method for constructing and evolving complex network is proposed. This method uses the concept of complex networks (mainly scale-free networks) and combines the essence of Immune Programming with Particle Swarm Optimization algorithm. The structure of a complex network genotype is evolved using Immune Programming algorithm with speciﬁc parameters, and the ﬁne tuning of the parameters encoded in the structure is accomplished using particle swarm optimization algorithm. The performance of proposed method is compared with Flexible Neural Tree (FNT), Neural Network (NN), and Wavelet Neural Network (WNN) by using the same breast cancer data set. The results of experimental study indicate that the proposed method is efficient.
Research Summary: Non-termination Analysis of Logic Programs
Authors: Dean Voets
Venue: Proceedings of the 25th International Conference on Logic Programming (2009)

An important advantage of Logic Programming (LP) is that a declarative programming style leads to more understandable and less error-prone computations. However, a declarative programming style also leads to less efficient, and in the extreme case, in non-terminating computations. Therefore, an important aspect of proving correctness of a program, is the analysis of the termination behavior of the program for a class of queries.
Change, change, change: three approaches
Authors: Tom Costello
Venue: Proceedings of the Fifteenth international joint conference on Artifical intelligence - Volume 2 (1997)

We consider the frame problem, that is, characterizing the assumption that properties tend to persist over time. We show that there are at least three distinct assumptions that can be made. We show the first assumption, which have been widely studied, is not naturally captured by circumscription. The first assumption is, "there is as little change as possible between one situation and the next". This is closely related to temporal projection. The second assumption is that actions have as few effects as possible. This has arisen in causal approaches. We show this assumption cannot be captured by any circumscription policy, as it compares models with different domains. We consider a third assumption--there are as many frame axioms true as possibl--which can be captured by circumscription. All three assumptions differ, which we show by giving examples. All agree on a small class of theories, those axiomatized by effect axioms and a class of sentences we call compatible binary domain constraints. Further, for a similar class of theories a deduction theorem holds, allowing observations, or facts about particular situations, to be brought through the non-monotonic consequence relation. This justifies approaches based on separating "observations" from "effects", and applying projection to the effects, to solve problems based on causality reasoning.
