Cartoon Detection Using Integral
Authors: Antonio Rama, Francesc Tarres, Laura Sanchez
Venue: Proceedings of the Eight International Workshop on Image Analysis for Multimedia Interactive Services (2007)

With the growth of digital television TV program classification has become a major research topic. Recent classification techniques have reported acceptable results for specific genre detection. Cartoons is one of these genres which has deceived some attention because of its importance in push scenarios where parents want to control their children's access to television. In this paper a flexible scheme based on a non-linear classifier called Fuzzy Integral is presented. This operator is supposed not only to classify but also to give a relevance measure to all the features involved in the classification. Preliminary results using this operator for cartoon detection are presented and compared with other well known statistical clasification methods like PCA, LDA or K-NN.
An Efficient Solution to the Critical Section Problem
Authors: Kia Makki, Niki Pissinou, E. K. Park
Venue: Proceedings of the 1994 International Conference on Parallel Processing - Volume 02 (1994)

In a distributed system of N sites an efficient solution to the critical section problem is proposed to allow multiple simultaneous entries to the Critical Section. The proposed solution is token-based, deadlock-free and free from starvation. In all cases except during the book keeping cycle of the algorithm, the number of message exchanges per Critical Section execution is less than or equal to 5. Only during the book keeping cycle which is not done very often the number of message exchanges per Critical Section execution reaches to at most N.

Experience Report: Use of SAP NetWeaver Technology to realize SOA-based BPM Tasks
Authors: R. Hirsch
Venue: Proceedings of the IEEE International Conference on Service-Oriented Computing and Applications (2007)

In corporate settings where service-oriented architecture (SOA) are being considered as a technical foundation to support Business Process Management (BPM) efforts, there are often questions regarding the optimal environment for process execution. This paper focuses on our experiences with such environments based on SAP NetWeaver technology - in particular Composite Application Framework's Guided Procedures. Although this paper will focus on our experiences with this product family and SAP's Enterprise SOA approach, others interested in the practical application in similar environments will find information about the problems faced and their resulting solutions. The hand-off between process design and process implementation in a corporate setting will be of particular interest to those examining the interaction between SOA theory and its real-world manifestation in a large organization.
Implementation and Evaluation of EduBingo for Arithmetic Drill
Authors: Sung-Bin Chang, Yi-Chan Deng, Hercy N. H. Cheng, Hui-Chun Liao, Fu-Yun Yu, Tak-Wai Chan
Venue: Proceedings of the The First IEEE International Workshop on Digital Game and Intelligent Toy Enhanced Learning (2007)

Bingo is a universally known, popular, and easy-toplay game. Following Bingo rules with some modifications, we have designed and implemented a game, called EduBingo, for practicing mathematics fractions. The game was implemented and experimented in a "one-to-one' technology enhanced classroom, where every student learns with a wireless enabled computing device. The experiment investigated students' preferences, system usability, as well as the effects on their affective states of a grade 4 class with 22 students. The result of the questionnaire indicates that the usability of EduBingo is acceptable and there was increase of various affective levels of the students. The data collected by the system, after analysis, implies that, for most students, accuracy and efficiency of solving fraction questions increased. The preliminary result also suggests some directions for further research.

A new robust system for 3D audio using loudspeakers
Authors: D. B. Ward
Venue: Proceedings of the Acoustics, Speech, and Signal Processing, 2000. on IEEE International Conference - Volume 02 (2000)

It is well known that the effectiveness of loudspeaker-based 3D audio systems is critically dependent on the listener being in a known position, the so-called "sweet spot". In this paper we propose a new system that provides increased robustness to perturbations such as head movement, reverberation, and different head shapes. The system is based on using a particular geometry that offers a combination of symmetric and asymmetric loudspeaker positions. This combination increases the bandwidth over which the proposed system is robust, when compared with existing 3D audio systems.
Seamless Integration of Sensor Network and Legacy Weather Databases by MetBroker
Authors: Seishi Ninomiya, Takuji Kiura, Atsushi Yamakawa, Tokihiro Fukatsu, Kei Tanaka, Hongyan Meng, Masayuki Hirafuji
Venue: Proceedings of the 2007 International Symposium on Applications and the Internet Workshops (2007)

Nowadays, we can use several meteorological databases through the Internet. They are, however, heterogeneous in access methods, data formats, available items etc., so that clients applications are generally tightly linked to particular databases. This causes inefficiency in developing client applications [1]. To solve this issue, we developed a data broker named MetBroker ([2] ((Laurenson, http://www.agmodel.net/) that provides client applications consistent accesses to such heterogeneous databases, hiding the heterogeneity and virtually integrating distributed databases. The basic idea was to provide a remote wrapper application to each database that translates the heterogeneity to a standardized format (Figure 1). At the end of May 2006, it covers more than 22,000 weather stations from 25 weather databases of the world.
Template base delegation
Authors: Ted Law
Venue: Proceedings of the 6th conference on USENIX Sixth C++ Technical Conference - Volume 6 (1994)

When a class derives from a template instantiation, the base class is called a template base class. Non-template base classes are more commonly used, but do not take into account the specific needs of the derived class. The base class can provide better service; it can be customized by becoming a template instantiation using the derived class and/or other classes as arguments. In this way, the template base class can tailor-make itself for the derived class, taking advantage of the knowledge of its type. For example, the template base class can type its methods appropriately for the derived class. Furthermore, inheriting publicly from a template base class makes it possible for the derived class to delegate part of its public type-specific interface to the base. This paper explores the advantages of template base delegation.
Product Line Enabled Intelligent Mobile Middleware
Authors: Weishan Zhang, Thomas Kunz, Klaus Marius
Venue: Proceedings of the 12th IEEE International Conference on Engineering Complex Computer Systems (2007)

Current mobile middleware is designed according to a "one-size-fits-all' paradigm, which lacks the flexibility for customization and adaptation to different situations, and does not support user-centered application scenarios well. In this paper we describe an ongoing intelligent mobile middleware research project called PLIMM that focuses on user-centered application scenarios. PLIMM is designed based on software product line ideas which make it possible for specialized customization and optimization for different purposes and hardware/software platforms. To enable intelligence, the middleware needs access to a range of context models. We model these contexts with OWL, focusing on user-centered concepts. The basic building block of PLIMM is the enhanced BDI agent where OWL context ontology logic reasoning will add indirect beliefs to the belief sets. Our approach also addresses the handling of ontology evolutions resulting from the timely adaptation of ontology to changes and the consistent propagation of these changes to all related artifacts, using Frame based product line configuration techniques.
A bispectrum based Gaussianity test using the bootstrap
Authors: A. M. Zoubir
Venue: Proceedings of the Acoustics, Speech, and Signal Processing, 1996. on Conference Proceedings., 1996 IEEE International Conference - Volume 05 (1996)

Testing the Gaussianity of a random process has been identified as an important problem in many engineering applications. Tests based on the bispectrum such as Subba Rao and Gabr's (1980) test or Hinich's (1982) test for Gaussianity have been proposed more than a decade ago. They have received considerable interest and application among the signal processing community. However, their application is limited to cases where a large amount of data is available. To overcome this problem, we incorporate the bootstrap into the bispectrum based Gaussianity test, and demonstrate how we can achieve high power. The proposed bootstrap procedure can also be used for setting confidence bands for bispectra.
Discrete coefficients filter banks and applications in image coding
Authors: C. W. Kok
Venue: Proceedings of the Acoustics, Speech, and Signal Processing, 1996. on Conference Proceedings., 1996 IEEE International Conference - Volume 03 (1996)

Discrete coefficient filter banks reduce the computational complexity for subband image coding systems. A new time domain formulation is proposed for the design of near-perfect reconstruction filter banks with discrete coefficients. It can be shown that the proposed design method yields an l/sup 2/ optimal solution which is considered to be practical in image coding applications. In addition, special emphasis is placed in designing filter banks with nonnegative scaling functions that smoothly decay to zero at block edges in order to reduce basis related artifacts. As a result, the reconstructed image does not suffer from blocking and ringing artifacts at medium bit rate (25:1 compression at 0.32 bit per pixel.).
Evaluating the Quality of Models Extracted from Embedded Real-Time Software
Authors: Joel Huselius, Johan Kraft, Hans Hansson, Sasikumar Punnekkat
Venue: Proceedings of the 14th Annual IEEE International Conference and Workshops on the Engineering of Computer-Based Systems (2007)

Due to the high cost of modeling, model-based techniques are yet to make their impact in the embedded systems industry, which still persist on maintaining code-oriented legacy systems. Re-engineering existing code-oriented systems to fit model-based development is a risky endeavor due to the cost and efforts required to maintain correspondence between the code and model. We aim to reduce the cost of modeling and model maintenance by automating the process, thus facilitating model-based techniques. We have previously proposed the use of automatic model extraction from recordings of existing embedded real-time systems. To estimate the quality of the extracted models of timing behavior, we need a framework for objective evaluation. In this paper, we present such a framework to empirically test and compare extracted models, and hence obtain an implicit evaluation of methods for automatic model extraction. We present a set of synthetic benchmarks to be used as test cases for emulating timing behaviors of diverse systems with varying architectural styles, and extract automatic models out of them. We discuss the difficulties in comparing response time distributions, and present an intuitive and novel approach along with associated algorithms for performing such a comparison. Using our empirical framework, and the comparison algorithms, one could objectively determine the correspondence between the model and the system being modeled.
A Speech Recognition IC Using Hidden Markov Models with Continuous Observation Densities
Authors: Wei Han, Kwok-Wai Hon, Cheong-Fat Chan, Chiu-Sing Choy, Kong-Pang Pun
Venue: Journal of VLSI Signal Processing Systems (2007)

This paper presents the design of a speech recognition IC using hidden Markov models (HMMs) with continuous observation densities. Results of offline and live recognition tests are also given. Our design employs a table look-up method to simplify the computation and hence the architecture of the circuit. Currently each state of the HMMs is represented by a double-mixture Gaussian distribution. With minor modifications, the proposed architecture can be extended to implement a recognizer in which models with higher order multi-mixture Gaussian distribution are used for more precise acoustic modeling. The test chip is fabricated with a 0.35 μm CMOS technology. The maximum operating frequency is 62.5 MHz at 3.3 V. For a 50-word vocabulary, the estimated recognition time is about 0.16 s. Using noise-corrupted utterances, the recognition accuracy is 93.8% for isolated English digits. Such a performance is comparable to the software implementation with the same algorithm. Live recognition test was also run for a vocabulary of 11 Chinese words. The accuracy is 91.8% for five male and five female speakers.
A P2P Groupware Framework based on Operational Transformations
Authors: Leandro Quiroga, Alejandro Fernandez
Venue: Proceedings of the 27th International Conference on Distributed Computing Systems Workshops (2007)

Groupware applications deal with propagation of changes to networked users, consistency maintenance on concurrent access, and provision of awareness. We have built a P2P groupware framework for the sub-domain of synchronous groupware. The framework is based on the concept of operational transformations to provide transparent change propagation and consistency maintenance. This paper provides an overview of the framework design and illustrates how to use it to build an application.

Dynamic host configuration for managing mobility between public and private networks
Authors: Allen Miu, Paramvir Bahl
Venue: Proceedings of the 3rd conference on USENIX Symposium on Internet Technologies and Systems - Volume 3 (2001)

The usage and service options of a pubic network generally differ from a private (enterprise or home) network and consequently, the two networks are often configured differently. The existence of both types of networks motivates our need to improve support and management of nomadic users who frequently roam between them. We describe a solution that allows client devices to configure themselves dynamically to adapt to the local network configuration. In addition to supporting mobility, we describe how our solution also provides fail-over mechanisms for providing highly available service, load balancing, and location services. Furthermore, our solution can be used to scale networks that are deployed in a large setting. We discuss in detail the various issues that need to be dealt with for achieving true device-level mobility, pointing out several unsolved problems in this area. The algorithms and software proposed in this paper have been implemented, are deployed, and are currently being used in a real-world public network that is operational at the Crossroads Mall in Bellevue, Washington.
Information Technology and Diversification: How Their Relationship Affects Firm Performance
Authors: Namchul Shin
Venue: Proceedings of the 40th Annual Hawaii International Conference on System Sciences (2007)

Information technology (IT) makes its fullest impact on organizations when it is deployed in conjunction with changes in business processes, structures, and strategies. While the importance of IT coupled with organizational changes for business performance has been widely discussed in the information systems (IS) literature, there has been little empirical research on the issue. Using Information Week's annual data set of IS budgets and the Compustat database, this research examines empirically the relationship between IT and diversification by employing multiple diversification measures. It also examines empirically the relative impact on performance of IT and diversification. Results show that diversification coupled with increased IT spending improves firm performance when its strategic emphasis is on related diversification. The results also show that firms place strategic focus on related diversification when they increase IT spending, and that they require more IT when their strategic emphasis is tilted toward related diversification. The findings imply that by providing a better means of coordination, IT enables scope economies, efficient utilization of business resources and collaboration across individual business units, eventually leveraging the benefits of diversification.

Template selection for LUT inverse halftoning and application to color halftones
Authors: M. Mese
Venue: Proceedings of the Acoustics, Speech, and Signal Processing, 2000. on IEEE International Conference - Volume 04 (2000)

In a previous paper we have proposed a method for inverse halftoning of monochrome images. It is a look up table (LUT) based method, obtained from the histogram gathered from a few sample halftone images and corresponding original images. The method is extremely fast (no filtering is required) and the image quality achieved is comparable to the best methods known for inverse halftoning. The method does not depend on the specific properties of halftoning method, and can be applied to any halftoning method. In this paper, we discuss how to choose the template recursively for the LUT. Afterwards, we propose an LUT based inverse halftoning method for color halftones. Color inverse halftoning can be done independently for each color plane or the correlation between the planes can be exploited. We also show how to choose the template for color inverse halftoning.
Topic-focused multi-document summarization using an approximate oracle score
Authors: John M. Conroy, Judith D. Schlesinger, Dianne P. O'Leary
Venue: Proceedings of the COLING/ACL on Main conference poster sessions (2006)

We consider the problem of producing a multi-document summary given a collection of documents. Since most successful methods of multi-document summarization are still largely extractive, in this paper, we explore just how well an extractive method can perform. We introduce an "oracle" score, based on the probability distribution of unigrams in human summaries. We then demonstrate that with the oracle score, we can generate extracts which score, on average, better than the human summaries, when evaluated with ROUGE. In addition, we introduce an approximation to the oracle score which produces a system with the best known performance for the 2005 Document Understanding Conference (DUC) evaluation.
On the use of matching pursuit time-frequency techniques for multiple-channel detection
Authors: K. Ghartey
Venue: Proceedings of the Acoustics, Speech, and Signal Processing, 2001. on IEEE International Conference - Volume 05 (2001)

In situations where the presence of a signal is to be detected in several noisy channels, often one channel will have higher signal-to-noise ratio (SNR) than the others. When the SNR on one channel is sufficiently high that the signal can be extracted from that channel, it may be possible to use the extracted signal to aid in detecting the presence of the signal on the other channels. The matching pursuit time-frequency method with matched signal dictionaries is used to extract a chirp signal from a noisy channel. The extracted signal is used in one channel of a generalized coherence (GC) detector with the goal of detecting the presence of the signal on other, even noisier, channels. This approach is compared via simulation to a GC detector that does not pre-process the highest SNR channel to extract the signal. Detector performance is shown to be significantly enhanced by matching pursuit signal extraction prior to coherence estimation.
Tourist: Self-Adaptive Structured Overlay
Authors: Huanan Zhang, Jinfeng Hu, Chunhui Hong, Dongsheng Wang
Venue: Proceedings of the Sixth International Conference on Networking (2007)

Structured overlays provide a basic substrate for many peer-to-peer systems. Existing structured overlays can be classified into two categories, O(logN)-hop ones and O(1)-hop ones. The former are suitable for large and dynamic systems, while the latter are suitable for small or stable ones. However, for the lack of adaptivity, it is difficult for a peer-to-peer system designer to choose from these two kinds of overlays because the eventual size and churn rate are not easy to predict in the design phase. To address this problem, we propose a self-adaptive structured overlay Tourist, which can adapt itself to the changing environment dynamically. Tourist nodes determine their routing table size autonomously: nodes with different capacities hold routing tables with different sizes. This makes Tourist sufficiently utilize all the nodes' allowable bandwidth to achieve as high routing efficiency as possible. Tourist also allows each node to adjust its routing table size dynamically, which is the essential reason for the self-adaptivity. Simulation results show that in a common 1,000,000-node system, Tourist can route all the messages within two hops and each node only pays no more than 1% bandwidth for its routing table maintenance.
