Modeling Timed User-Interactions in Multimedia Documents
Venue: Proceedings of the 1996 International Conference on Multimedia Computing and Systems (1996)

Interactive multimedia documents (or systems) can be characterized by active user participation and the diversity of multimedia information accessed at various levels of granularity. They need to support extensive user participation in selecting and tailoring the information and its presentation. Multimedia information fragments may vary from portions of video, pieces of audio, newspaper quotations, or chapters of a book. Effectively managing the creation, evolution, and complexity of multimedia documents formed by combining media fragments is an essential capability. We consider the hyperstory model of a multimedia document, where a document is structured hierarchically in three dimensions: time, space, and asynchrony. The model provides a layered approach in structuring multimedia documents, thus reducing the complexities of large systems. The hyperstory model supports user interactions that are timed, and also supports preemptive resuming. Timed user interactions with the document are modeled with a newly introduced timed Petri-net, TPN*. The TPN* is used to infer the behavior of the system. This paper describes the TPN* modeling, analy- sis, and application to the hyperstory model. The ACM Portal is published by the Association for Computing Machinery. Copyright © 2010 ACM, Inc.

Moving towards efficient decision tree construction
Authors: B. Chandra, P. Paul Varghese
Venue: Information Sciences: an International Journal (2009)

Motivated by the desire to construct compact (in terms of expected length to be traversed to reach a decision) decision trees, we propose a new node splitting measure for decision tree construction. We show that the proposed measure is convex and cumulative and utilize this in the construction of decision trees for classification. Results obtained from several datasets from the UCI repository show that the proposed measure results in decision trees that are more compact with classification accuracy that is comparable to that obtained using popular node splitting measures such as Gain Ratio and the Gini Index.
HG-Tree: An Index Structure for Multimedia Databases
Venue: Proceedings of the 1996 International Conference on Multimedia Computing and Systems (1996)

We propose a new index structure, called the HG-tree, to support content-based retrieval in multimedia databases. Our goals are twofold: increasing the storage utilization and decreasing the directory coverage of the index tree. The first goal is achieved by absorbing splitting if possible, and when splitting is necessary, converting two nodes to three. This is done by proposing a good ordering on the directory nodes. The second goal is achieved by representing the directory regions compactly. We note that there is a trade-off between above two design goals, but the HG-tree is so flexible that it can control the trade-off. We present the design of our index tree and associated algorithms. In addition, we report the results of a series of tests, comparing the proposed index tree with the buddy-tree, which is one of the successful access methods for a multidimensional space. The results show that the superiority of our method. Keywords: content-based, database, index, image, multimedia The ACM Portal is published by the Association for Computing Machinery.

Towards the Virtual Internet Gallery
Authors: Andreas Miiller, Martin Leissler, Matthias Hemmje, Erich Neuhold
Venue: Proceedings of the 1999 IEEE International Conference on Multimedia Computing and Systems - Volume 02 (1999)

The still rapidly growing Internet offers new ways to reach an increasing number of people in all areas of life. More and more companies take advantage of this fact by advertising and selling their products through this new electronic media. Art is a great example for using this new approach, because the visualization is the most important aspect and the physical presence of the exhibited object has just a secondary significance for the buying process, in contrary to other products (e.g. instruments, perfume, cars, etc.). This paper introduces an electronic service for galleries and artists to exhibit their artwork on the Internet easily and efficiently. The Virtual Internet Gallery (TUG) utilizes a database to offer fast search functionality and per$orms a 30 visualization of the user's query result, applying VRML. Users, who are interested in the exhibited art, can contact the gallery or artist directly through the system.
Online purchase intentions: A multi-channel store image perspective
Authors: Tibert Verhagen, Willemijn van Dolen
Venue: Information and Management (2009)

The advantages of the bricks-and-clicks retail format in the battle for the online customer has been widely discussed but empirical research on it has been limited. We applied a multi-channel store image perspective to assess its influence on online purchase intentions. Drawing on a sample of 630 customers of a large music retail store in the Netherlands, the results demonstrated that offline and online store perceptions directly influenced online purchase intention. In addition, our findings confirmed that offline store impressions were used as references for their online store counterparts. Synergy and reference effects are discussed.
Predicting intrusion goal using dynamic Bayesian network with transfer probability estimation
Authors: Li Feng, Wei Wang, Lina Zhu, Yi Zhang
Venue: Journal of Network and Computer Applications (2009)

Predicting the intentions of an observed agent and taking corresponding countermeasures is the essential part for the future proactive intrusion detection systems (IDS) as well as intrusion prevention systems (IPS). In this paper, an approach of dynamic Bayesian network with transfer probability estimation was developed to predict whether the goal of system call sequences is normal or not, with early-warnings being launched, so as to ensure that some appropriate countermeasures could be taken in advance. Since complete set of system call state transfer can hardly be built in real environments, the empirical results show that the newly emerging system call transfer would have great impact on the prediction performance if we straightly use dynamic Bayesian network without transfer probability estimation. Therefore, we estimate the probability of new state transfer to predict the goals of system call sequences together with those in conditional probability table (CPT). It surmounts the difficulties of manually selecting compensating parameters with dynamic Bayesian network approach [Feng L, Guan X, Guo S, Gao Y, Liu P. Predicting the intrusion intentions by observing system call sequences. Computers & Security 2004; 23/3: 241-252] and obviously makes our prediction model more applicable. The University of New Mexico (UNM) and KLINNS data sets were analyzed and the experimental results show that it performs very well for predicting the goals of system call sequences with high accuracy and furthermore dispenses with much more manual work for selecting compensating parameters.
An Enhanced Distortion Measure Based VBR for Waveform Interpolative Speech Coders
Authors: Heesik Yang, Sangbae Jeong, Minsoo Hahn
Venue: IEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences (2008)

In our previous study, a distortion measure based variable bit rate (DM-VBR) scheme in waveform interpolation (WI) coders was proposed. In this paper, the repetition method is proposed to estimate non-transmitted parameters instead of the extrapolation method. For the further reduction of slowly evolving waveform (SEW) bit rates, the dimensions of the past parameters, which are different from those of the current parameters, are converted to match the dimension of the current ones. Distortions between interpolated sub-frames and original sub-frames are measured for the reduction of the SEW parameters. And the usefulness of several other distortion measures is also investigated instead of the simple log spectral distortion. Experimental results show that the coder adopting the new schemes offers above 41% bit rate reduction with almost unnoticeable output speech degradation.

Venue: Proceedings of the 21st British CHI Group Annual Conference on HCI 2007: People and Computers XXI: HCI...but not as we know it - Volume 1 (2007)

Despite being nominated as a key potential interaction technique for supporting today's mobile technology user, the widespread commercialisation of speech-based input is currently being impeded by unacceptable recognition error rates. Developing effective speech-based solutions for use in mobile contexts, given the varying extent of background noise, is challenging. The research presented in this paper is part of an ongoing investigation into how best to incorporate speech-based input within mobile data collection applications. Specifically, this paper reports on a comparison of three different commercially available microphones in terms of their efficacy to facilitate mobile, speech-based data entry. We describe, in detail, our novel evaluation design as well as the results we obtained.
Taking the time to care: empowering low health literacy hospital patients with virtual nurse agents
Authors: Timothy W. Bickmore, Laura M. Pfeifer, Brian W. Jack
Venue: Proceedings of the 27th international conference on Human factors in computing systems (2009)

Ninety million Americans have inadequate health literacy, resulting in a reduced ability to read and follow directions in the healthcare environment. We describe an animated, empathic virtual nurse interface for educating and counseling hospital patients with inadequate health literacy in their hospital beds at the time of discharge. The development methodology, design rationale, and two iterations of user testing are described. Results indicate that hospital patients with low health literacy found the system easy to use, reported high levels of satisfaction, and most said they preferred receiving the discharge information from the agent over their doctor or nurse. Patients also expressed appreciation for the time and attention provided by the virtual nurse, and felt that it provided an additional authoritative source for their medical information.
Reliable Data Delivery Algorithm Based on Differentiated Service in WSNs
Authors: Xin-Lian Zhou, Run-Yun Wang
Venue: Proceedings of the 2009 International Conference on Electronic Computer Technology (2009)

Reliable data delivery is key problem in WSN. This article introduces network differentiated service, raises Path_Choose algorithm with differentiated service mechanism, which either adopt common data and periodically measuring data, or dispose exigent data. Commonly, source nodes select one non-intersectant path between clusters to deliver data depending on probability, low requirement to exigency; once emergencies, insure exigent data correctly arriving Sink, and meantime start up all non-intersectant paths to enhance reliability. Simulated experiment indicates, although it increases slightly energy consumption, obtains higher data reliability than approved LEACH.

Venue: Microelectronic Engineering (2009)

We report material and electrical properties of tungsten silicide metal gate deposited on 12in. wafers by chemical vapor deposition (CVD) using a fluorine free organo-metallic (MO) precursor. We show that this MOCVD WSi"x thin film deposited on a high-k dielectric (HfSiO:N) shows a N+ like behavior (i.e. metal workfunction progressing toward silicon conduction band). We obtained a high-k/WSi"x/polysilicon ''gate first'' stack (i.e. high thermal budget) providing stable equivalent oxide thickness (EOT) of ~1.2nm, and a reduction of two decades in leakage current as compared to SiO"2/polysilicon standard stack. Additionally, we obtained a metal gate with an equivalent workfunction (EWF) value of ~4.4eV which matches with the +0.2eV above Si midgap criterion for NMOS in ultra-thin body devices.
Delay constrained uplink scheduling policy for rtPS-ertPS service in IEEE 802.16e BWA systems
Authors: Der-Jiunn Deng, Li-Wei Chang, Chih-Heng Ke, Yueh-Min Huang, J. Morris Chang
Venue: International Journal of Communication Systems (2009)

WiMAX is a promising broadband wireless networking technology and is expected to take the place of broadband access solutions such as DSL and cable. Owing to its superior support in mobility, it is expected to provide integrated voice and data service to realize broadband mobile computing. In order to reach better quality-of-service (QoS) requirements for real-time applications, the IEEE 802.16e standard defines five different services among traffic categories with different multimedia requirements. However, the problem of choosing the right set of medium access control parameters and packet scheduling policy to provide strict QoS guaranteed in IEEE 802.16e Broadband Wireless Access (BWA) systems remains unsolved and left as an open issue. In this paper, we propose a novel polling-based uplink packet scheduling policy for real-time Polling Service and extended real-time Polling Service (rtPS-ertPS) traffic to support real-time applications, with strict delay requirements, such as variable bit rate (VBR) traffic in IEEE 802.16e BWA systems. The proposed transmit-permission policy can derive sufficient conditions such that all the rtPS-ertPS sources satisfy their time constraints to provide deterministic QoS guarantees. In addition to theoretical analysis, simulations are conducted to evaluate the performance of the proposed scheme. As it turns out, our design provides a good quality performance in the IEEE 802.16e BWA systems. Copyright &copy; 2008 John Wiley & Sons, Ltd.

A new integrated decision-making approach for design alternative selection for supporting complex product development
Authors: Zaifang Zhang, Xuening Chu
Venue: International Journal of Computer Integrated Manufacturing (2009)

Design alternative selection is regarded as a crucial activity in complex product development. The traditional decision-making methods barely consider the design alternative evaluation of complex products or integrate the voices of customers into the decision process systematically. The aim of this paper is to improve the effectiveness of decision making about multiple design alternatives in complex product development under uncertainty. Based on the integration of quality function deployment and group decision making, a new decision-making approach is proposed for assisting product designers in selecting the design alternatives of complex products. Meanwhile, fuzzy set theory is incorporated in order to capture the vagueness and uncertainty that exists in the decision process. In this study, a complex product is divided into multi-parts to form a hierarchical structure. Fuzzy quality function deployment is used for translating customer requirements into the priorities of these parts. Furthermore, a fuzzy multi-criteria group decision-making method is employed for evaluating the performance of part alternatives. All design alternatives are ranked and then selected according to the multiplied evaluation scores of parts with their weights. This proposed approach is applied in a real-world example of a horizontal directional drilling machine. In addition, how the importance weights of customer requirements and evaluation criteria change are analysed under various risk environments.

Toward a unified theory of the multitasking continuum: from concurrent performance to task switching, interruption, and resumption
Authors: Dario D. Salvucci, Niels A. Taatgen, Jelmer P. Borst
Venue: Proceedings of the 27th international conference on Human factors in computing systems (2009)

Multitasking in user behavior can be represented along a continuum in terms of the time spent on one task before switching to another. In this paper, we present a theory of behavior along the multitasking continuum, from concurrent tasks with rapid switching to sequential tasks with longer time between switching. Our theory unifies several theoretical effects - the ACT-R cognitive architecture, the threaded cognition theory of concurrent multitasking, and the memory-for-goals theory of interruption and resumption - to better understand and predict multitasking behavior. We outline the theory and discuss how it accounts for numerous phenomena in the recent empirical literature.
Privacy Preserving Attribute Reduction Based on Rough Set
Authors: Zhengyou Zhou, Liusheng Huang, Ye Yun
Venue: Proceedings of the 2009 Second International Workshop on Knowledge Discovery and Data Mining (2009)

Attribute reduction, as a part of preprocesses, plays an important role in data mining. Privacy ought to be preserved while conducting attribute reduction on distributed data. However, to the best of our knowledge, there exists no algorithm about attribute reduction for the present. In this paper, we represent two privacy preserving attribute reduction algorithms based on rough set. One is on the vertically partitioned data. We develop secure sum of matrices and secure set intersection for it. The other is on the horizontally partitioned data, mainly using secure set union. The correctness and security of the two algorithms are also analyzed. The results show that both of the two algorithms are correct and secure.
Parallel sort and join for high speed database machine operations
Authors: Mamoru Maekawa
Venue: Proceedings of the May 4-7, 1981, national computer conference (1981)

This paper proposes a parallel joining and sorting algorithm that completes in about log N steps for N records. The algorithm is intended for large database systems. The algorithm and its required processor interconnection are simple and realistic. Thus, a performance improvement of three to four orders of magnitude can be realistically expected by applying this algorithm to database machines. Analysis is primarily made by simulations.
