A Generic Protocol for Controlling Access to Mobile Services
Authors: Shuhong Wang, Yingjiu Li, Bo Zhu, Nan Hu
Venue: Proceeding of the 2005 conference on Applied Public Key Infrastructure: 4th International Workshop: IWAP 2005 (2005)

Mobile services have been growing fast to facilitate business in wireless network environment. It is both critical and challenging to maintain security and anonymity so as to provide high quality services. In this paper, we propose a ticket-based architecture and a generic protocol for controlling access to mobile services. Our protocol has the following properties. First, it is a generic solution independent of cryptographic algorithms and service models. Second, it is secure against various malicious attacks on mobile services. Third, it provides identity anonymity for customers and/or service providers depending on business requirements. Fourth, it is flexible in dynamic environments where customers and/or service providers are cross multiple domains. We also show an efficient implementation option of this generic protocol based on elliptic curve digital signature algorithm.
Mining Combinatorial Effects on Quantitative Traits from Protein Expression Data
Authors: Takuya Yoshihiro, Etsuko Inoue, Masaru Nakagawa
Venue: Proceeding of the 2008 conference on Knowledge-Based Software Engineering: Proceedings of the Eighth Joint Conference on Knowledge-Based Software Engineering (2008)

In this paper we proposed a data mining method to find interesting relation among the small number of proteins and a quantitative trait from protein expression data. It is practically important to find small number of proteins which in combination effects on some characteristics of samples because it motivates further experiments to investigate the function of the proteins. Further, treating quantitative trait rather than categorical data is also practically important since considerable part of characteristics of samples is represented by quantitative values. Our data mining method apply discriminant analysis into protein expression data and quantitative trait data to derive interesting relations among them.
Research on Personality Mining System in E-Learning by Using Improved Association Rules
Authors: Luo Qi, Yanwen Wu, Liyong Wan, Ying Yu
Venue: Proceeding of the 2006 conference on Learning by Effective Utilization of Technologies: Facilitating Intercultural Understanding (2006)

To meet the personalized needs of E-learning, an improved association mining rules was proposed in the paper. First, data cube from database was established. Then, frequent item-set that satisfies the minimum support on data cube was mined out. Furthermore, association rules of frequent item-set were generated. Finally, redundant association rules through the relative method in statistics were wiped off. The algorithm had two advantages, the first was that the execution time was short while searching for the frequent item-set; the second was that the precision of the rules was high. The algorithm was also used in personality mining system based on E-learning model (PMSEM).The results manifested that the algorithm was effective.
National culture practices and societal information dissemination capacity
Authors: Omar E. M. Khalil, Ahmed Seleim
Venue: Proceedings of the 2009 conference on Information Science, Technology and Applications (2009)

This research adopts the national cultural taxonomy of House and colleagues [47] and Information Age statistics from the International Development Indicators of the World Bank [79] to explore the impact of national culture practices on information dissemination capacity at the societal level. Nine hypotheses were formulated and tested. Countries with high information dissemination capacities were found to have a pattern of high uncertainty avoidance, high future orientation, high institutional collectivism, low in-group collectivism, and low gender egalitarianism practices. However, the results of the national culture values-based and culture practices-based regression models suggest that national culture values are more appropriate predictors of societal information dissemination capacity.
ShiverPad: A device capable of controlling shear force on a bare finger
Authors: Erik C. Chubb, J. Edward Colgate, Michael A. Peshkin
Venue: Proceedings of the World Haptics 2009 - Third Joint EuroHaptics conference and Symposium on Haptic Interfaces for Virtual Environment and Teleoperator Systems (2009)

We discuss the theory, design, and performance of a flat-panel tactile display capable of controlling shear force on a finger. In previous research a TPaD variable friction device was presented. It modulates friction by using vertical ultrasonic vibrations to form a squeeze film of air between the finger and the horizontal glass surface. In this research, a TPaD is oscillated in the horizontal plane at 20-100Hz while alternating between low and high friction at the same frequency. As the plate moves in one direction, the squeeze film is turned on and friction is reduced. As the plate moves in the opposite direction, the squeeze film is turned off and the friction increases. The net time-averaged force is non-zero and can be used as a source of shear force to a finger in contact with the surface. We demonstrate the implementation of line sources and sinks using this new technology.
No bull, no spin: a comparison of tags with other forms of user metadata
Authors: Catherine C. Marshall
Venue: Proceedings of the 9th ACM/IEEE-CS joint conference on Digital libraries (2009)

User-contributed tags have shown promise as a means of indexing multimedia collections by harnessing the combined efforts and enthusiasm of online communities. But tags are only one way of describing multimedia items. In this study, I compare the characteristics of public tags with other forms of descriptive metadata'titles and narrative captions'that users have assigned to a collection of very similar images gathered from the photo-sharing service Flickr. The study shows that tags converge on different descriptions than the other forms of metadata do, and that narrative metadata may be more effective than tags for capturing certain aspects of images that may influence their subsequent retrieval and use. The study also examines how photographers use peoples' names to personalize the different types of metadata and how they tell stories across short sequences of images. The study results are then brought to bear on design recommendations for user tagging tools and automated tagging algorithms and on using photo sharing sites as de facto art and architecture resources.
GO! with Access 2007 Comprehensive, 1st edition
Authors: Shelley Gaskin, Carolyn McLellan, Susan Dozier, Kris Townsend
Venue:  (2007)

The primary goal of the GO! Series, aside from teaching computer applications, is ease of implementation, with an approach that is based on clearly-defined projects for students and a one of a kind supplements package. GO!s project-based approach clusters the learning objectives around the projects rather than around software features. Teaches students to solve real problems as they practice and learn the features. Ideal for students and individuals seeking an introduction to Internet Explorer.
But that was in another country: agents and intercultural empathy
Authors: Ruth Aylett, Natalie Vannini, Elisabeth Andre, Ana Paiva, Sibylle Enz, Lynne Hall
Venue: Proceedings of The 8th International Conference on Autonomous Agents and Multiagent Systems - Volume 1 (2009)

This paper discusses the development of a believable agent-based educational application designed to develop inter-cultural empathy for 13--14 year old students. It considers relevant work in cultural taxonomy and adaptation to other cultures as well as work showing that users are sensitive to the perceived culture of believable interactive characters. It discusses how an existing affective agent architecture was developed to model culturally-specific agent behaviour. Finally, it considers the role of interaction modalities in supporting an empathic engagement with culturally-specific characters.
Discount-Optimal Infinite Runs in Priced Timed Automata
Authors: Uli Fahrenberg, Kim G. Larsen
Venue: Electronic Notes in Theoretical Computer Science (ENTCS) (2009)

We introduce a new discounting semantics for priced timed automata. Discounting provides a way to model optimal-cost problems for infinite traces and has applications in optimal scheduling and other areas. In the discounting semantics, prices decrease exponentially, so that the contribution of a certain part of the behaviour to the overall cost depends on how far into the future this part takes place. We consider the optimal infinite run problem under this semantics: Given a priced timed automaton, find an infinite path with minimal discounted price. We show that this problem is computable, by a reduction to a similar problem on finite weighted graphs. The proof relies on a new theorem on minimization of monotonous functions defined on infinite-dimensional zones, which is of interest in itself.

Performance evaluation of routing protocols for mobile ad hoc networks using statistical Taguchi's experimental design
Authors: Muhammad Hisyam Lee, Mazalan Sarahintu, Hazura Mohamed, Bahrom Sanugi, Stephan Olariu, Azami Zaharim
Venue: Proceedings of the 13th WSEAS international conference on Applied mathematics (2008)

This paper presents the application of Taguchi approach in investigating the performance of mobile ad hoc networks (MANETs) with respect to drop rates. The performance of MANETs was influenced very much by the routing protocol designs and quantitative factors such as network size, terrain, pause-time, node speed, transmission range, traffic load, and packet rates. The NS-2 simulator was used for the simulation of the MANETs under a specific scenario. The tools of Taguchi approach such as L12 orthogonal array, analysis of signal-to-noise ratio, and analysis of variance (ANOVA) were employed. Results showed that the effects of network size, terrain, node speed, transmission range, traffic load, packet rates, and routing were found to be statistically significant, and the most significant factor was transmission range. Using the combination of optimal levels of the significant factors, the specific values of drop rates was predicted. Good agreement between the predicted drop rates and actual drop rates was observed in this study.
Single-peaked consistency and its complexity
Authors: Bruno Escoffier, Jérôme Lang, Meltem Öztürk
Venue: Proceeding of the 2008 conference on ECAI 2008: 18th European Conference on Artificial Intelligence (2008)

A common way of dealing with the paradoxes of preference aggregation consists in restricting the domain of admissible preferences. The most well-known such restriction is single-peakedness. In this paper we focus on the problem of determining whether a given profile is single-peaked with respect to some axis, and on the computation of such an axis. This problem has already been considered in [2]; we give here a more efficient algorithm and address some related issues, such as the number of orders that may be compatible with a given profile, or the communication complexity of preference aggregation under the single-peakedness assumption.
Modeling interactions between adjacent nucleosomes improves genome-wide predictions of nucleosome occupancy
Authors: Shai Lubliner, Eran Segal
Venue: Bioinformatics (2009)

Motivation: Understanding the mechanisms that govern nucleosome positioning over genomes in vivo is essential for unraveling the role of chromatin organization in transcriptional regulation. Until now, models for predicting genome-wide nucleosome occupancy have assumed that the DNA associations of neighboring nucleosomes on the genome are independent. We present a new model that relaxes this independence assumption by modeling interactions between adjacent nucleosomes. Results: We show that modeling interactions between adjacent nucleosomes improves genome-wide nucleosome occupancy predictions in an in vitro system that includes only nucleosomes and purified DNA, where the resulting model has a preference for short spacings (linkers) of less than 20 bp in length between neighboring nucleosomes. Since nucleosome occupancy in vitro depends only on properties intrinsic to nucleosomes, these results suggest that the interactions we find are intrinsic to nucleosomes and do not depend on other factors, such as transcription factors and chromatin remodelers. We also show that modeling these intrinsic interactions significantly improves genome-wide predictions of nucleosome occupancy in vivo.

Point&Connect: intention-based device pairing for mobile phone users
Authors: Chunyi Peng, Guobin Shen, Yongguang Zhang, Songwu Lu
Venue: Proceedings of the 7th international conference on Mobile systems, applications, and services (2009)

Point&Connect (P&C) offers an intuitive and resilient device pairing solution on standard mobile phones. Its operation follows the simple sequence of point-andconnect: when a user plans to pair her mobile phone with another device nearby, she makes a simple hand gesture that points her phone towards the intended target. The system will capture the user's gesture, understand the target selection intention, and complete the device pairing. P&C is intention-based, intuitive, and reduces user efforts in device pairing. The main technical challenge is to come up with a simple system technique to effectively capture and understand the intention of the user, and pick the right device among many others nearby. It should further work on any mobile phones or small devices without relying on infrastructure or special hardware. P&C meets this challenge with a novel collaborative scheme to measure maximum distance change based on acoustic signals. Using only a speaker and a microphone, P&C can be implemented solely in user-level software and work on COTS phones. P&C adds additional mechanisms to improve resiliency against imperfect user actions, acoustic disturbance, and even certain malicious attacks. We have implemented P&C in Windows Mobile phones and conducted extensive experimental evaluation, and showed that it is a cool and effective way to perform device pairing.
Determinacy analysis as a diclique extracting task
Authors: Grete Lind, Rein Kuusik
Venue: Proceedings of the 2nd conference on European computing conference (2008)

In many papers the essence of Determinacy Analysis has been treated, but none of them determines to what field this method belongs. Author of the method compares it to the classical factor analysis. In this paper we show that Determinacy Analysis is a method that solves tasks of data mining. We also show how this method can be reduced to the graph-theoretical diclique-finding task. This allows presenting new approaches to DA and exclude manual work.
Planar graphs with maximum degree 8 and without adjacent triangles are 9-totally-colorable
Authors: Dingzhu Du, Lan Shen, Yingqian Wang
Venue: Discrete Applied Mathematics (2009)

The Total Coloring Conjecture, in short, TCC, says that every simple graph is (@D+2)-totally-colorable where @D is the maximum degree of the graph. Even for planar graphs this conjecture has not been completely settled yet. However, every planar graph with @D>=9 has been proved to be (@D+1)-totally-colorable. In this paper, we prove that planar graphs with maximum degree 8 and without adjacent triangles are 9-totally-colorable.
Burstiness and scaling in the structure of low-power wireless links
Authors: Tal Rusak, Philip Levis
Venue: ACM SIGMOBILE Mobile Computing and Communications Review (2009)

We observe that low-power wireless links have non-trivial time-scaling characteristics at both the physical- and link-layers. Packet reception rate (PRR) analysis shows that links are bursty rather than constant, i.e., their reception quality varies greatly from the overall packet reception rate at different times. Furthermore, this variation is seen at many timescales. We provide a possible explanation for burstiness using wavelet analysis of RSSI traces from a variety of wireless links. We show that these traces can be considered as consistent with statistical self-similarity but not with long range dependence. Using the variance in RSSI, we suggest a way to easily characterize when scaling occurs. Finally, while current simulators do not capture scaling, we propose and validate a possible modeling technique for network links that conforms to scaling phenomena.
Joint pricing and design of urban highways with spatial and user group heterogeneity
Authors: Loukas Dimitriou, Theodore Tsekeris, Antony Stathopoulos
Venue: Netnomics (2009)

This paper addresses the joint optimization of capacity investments and toll charges imposed on multi-group users in monopolistic private highways within general road networks. A game-theoretic formulation is provided that leads to a nonconvex bilevel program. The proposed modeling framework handles several complex issues raised in realistic applications, such as regulations on the levels of tolls and service, and the discrete nature of highway capacity, using a genetic optimization technique. Real-application results show the importance of considering the spatial heterogeneity of prices, and the tradeoff between investments and pricing strategies in regulated private highways.
Mendelian error detection in complex pedigrees using weighted constraint satisfaction techniques
Authors: Marti Sanchez, Simon de Givry, Thomas Schiex
Venue: Proceeding of the 2007 conference on Artificial Intelligence Research and Development (2007)

With the arrival of high throughput genotyping techniques, the detection of likely genotyping errors is becoming an increasingly important problem. In this paper we are interested in errors that violate Mendelian laws. The problem of deciding if Mendelian error exists in a pedigree is NP-complete [1]. Existing tools dedicated to this problem may offer different level of services: detect simple inconsistencies using local reasoning, prove inconsistency, detect the source of error, propose an optimal correction for the error. All assume that there is at most one error. In this paper we show that the problem of error detection, of determining the minimum number of error needed to explain the data (with a possible error detection) and error correction can all be modeled using soft constraint networks. Therefore, these problems provide attractive benchmarks for weighted constraint network (WCN) solvers. Because of their sheer size, these problems drove us into the development of a new WCN solver toulbar21 which solves very large pedigree problems with thousands of animals, including many loops and several errors. This paper is a summary of an extended version to appear [17].
An interface agent for attention manipulation
Authors: Tibor Bosse, Rianne van Lambalgen, Peter-Paul van Maanen, Jan Treur
Venue: Proceedings of The 8th International Conference on Autonomous Agents and Multiagent Systems - Volume 2 (2009)

This paper describes the idea of an interface agent that is able to manipulate the visual attention of a human, in order to support naval crew in a tactical picture compilation task. The agent will consist of four submodels, including a model to reason about a subject's attention. In a study (not presented here) a practical case study was formally analysed, and the results were verified using automated checking tools. These results show how a human subject's attention is manipulated by adjusting luminance, based on comparative assessment involving a descriptive and a prescriptive model of the subject's attention.
Tradeoff analysis between knowledge assessment approaches
Authors: Michel C. Desmarais, Shunkai Fu, Xiaoming Pu
Venue: Proceeding of the 2005 conference on Artificial Intelligence in Education: Supporting Learning through Intelligent and Socially Informed Technology (2005)

The problem of modeling and assessing an individual's ability level is central to learning environments. Numerous approaches exists to this end. Computer Adaptive Testing (CAT) techniques, such as IRT and Bayesian posterior updating, are amongst the early approaches. Bayesian networks and graphs models are more recent approaches to this problem. These frameworks differ on their expressiveness and on their ability to automate model building and calibration with empirical data. We discuss the implication of expressiveness and data-driven properties of different frameworks, and analyze how it affects the applicability and accuracy of the knowledge assessment process. We conjecture that although expressive models such as Bayesian networks provide better cognitive diagnostic ability, their applicability, reliability, and accuracy is strongly affected by the knowledge engineering effort they require. We conclude with a comparative analysis of data driven approaches and provide empirical estimates of their respective performance for two data sets.
Philosophical Frameworks for Understanding Information Systems
Authors: Andrew Basden
Venue:  (2007)

Information systems have five main areas of research and practice in which humans relate to information and communications technology. Typically isolated from one another, these areas are: the nature of computers and information, the creation of information technologies, the development of artifacts for human use, the usage of information systems, and information technology as our environment. Philosophical Frameworks for Understanding Information Systems strives to develop philosophical frameworks for these five areas and provides researchers, scholars, and practitioners in fields such as information systems, public administration, library science, education, and business management with an exemplary reference resource.
