Authors: Gregor Broll, John Hamard, Massimo Paolucci, Markus Haarländer, Matthias Wagner, Sven Siorpaes, Enrico Rukzio, Albrecht Schmidt, Kevin Wiesner
Venue: Proceedings of the 9th international conference on Human computer interaction with mobile devices and services (2007)

The proposed demonstration is based on the work performed in the PERCI project and presents a generic framework to access and interact with Web Services through mobile interaction with real world objects. The demonstration will put a focus on the front-end of the framework that comprises augmented posters for mobile ticketing as well as a mobile client application for the interaction with associated services. By supporting Physical Mobile Interaction techniques such as Touching or Pointing, the framework tries to make mobile service interaction more intuitive and shift its focus from the menus of mobile devices to augmented physical objects.

Authors: Mainul Haque, Bai Larry Li
Venue: Proceedings of the Tenth International Conference on Computer Modeling and Simulation (2008)

Holling-Tanner model is revised with ratio-dependent functional response since ratio-dependent functional response is more appropriate when predator involves serious searching process. The essential mathematical features of the modified model have been analyzed with the help of local stability, global stability, bifurcation theory. Finally, analytical results have been interpreted in terms of ecology.
End-to-end diagnostics in IPTV architectures
Authors: Kamakshi Sridhar, Gérard Damm, Hakki C. Cankaya
Venue: Bell Labs Technical Journal (2008)

The introduction of new revenue-generating services like Internet Protocol television (IPTV) promises to bring to the end user a much more personal-ized communication and entertainment experience at an affordable cost. IPTV brings new features like video on demand (VoD), broadcast TV, and customized ad insertion, along with more traditional voice and data services whose realization requires a wholesale deployment of existing and new protocols and new network elements. Configuration, maintenance and troubleshooting of such networks, customized for each end user, are complex, and it is widely believed that providing diagnostics mechanisms is of substantial importance for rollout of IPTV. This paper describes research efforts at Alcatel-Lucent toward the definition and development of end-to-end diagnostics for IPTV architectures, comprising probes and mechanisms to detect problems in the network and to issue corrective measures. &copy; 2008 Alcatel-Lucent.
Analysis of Packet Relaying Models and Incentive Strategies in Wireless Ad Hoc Networks with Game Theory
Authors: Lu Yan, Stephen Hailes, Licia Capra
Venue: Proceedings of the 22nd International Conference on Advanced Information Networking and Applications (2008)

In wireless ad hoc networks, nodes are both routers and terminals, and they have to cooperate to communicate. Cooperation at the network layer means routing (finding a path for a packet), and forwarding (relaying packets for others). However, because wireless nodes are usually constrained by limited power and computational resources, a selfish node may be unwilling to spend its resources in forwarding packets that are not of its direct interest, even though it expects other nodes to forward its packets to the destination. In this paper, we propose a game-theoretic model to facilitate the study of the non-cooperative behaviors in wireless ad hoc networks and analyze incentive schemes to motivate cooperation among wireless ad hoc network nodes to achieve a mutually beneficial networking result.
Cut-out image mosaics
Authors: Jeff Orchard, Craig S. Kaplan
Venue: Proceedings of the 6th international symposium on Non-photorealistic animation and rendering (2008)

An image mosaic is a rendering of a large target image by arranging a collection of small source images, often in an array, each chosen specifically to fit a particular block of the target image. Most mosaicking methods are simplistic in the sense that they break the target image into regular tiles (e.g., squares or hexagons) and take extreme shortcuts when evaluating the similarity between target tiles and source images. In this paper, we propose an efficient method to obtain higher quality mosaics that incorporate a number of process improvements. The Fast Fourier Transform (FFT) is used to compute a more fine-grained image similarity metric, allowing for optimal colour correction and arbitrarily shaped target tiles. In addition, the framework can find the optimal sub-image within a source image, further improving the quality of the matching. The similarity scores generated by these high-order cost computations are fed into a matching algorithm to find the globally-optimal assignment of source images to target tiles. Experiments show that each improvement, by itself, yields a more accurate mosaic. Combined, the innovations produce very high quality image mosaics, even with only a few hundred source images.
Calibration of abstract performance models for system-level design space exploration
Authors: Andy D. Pimentel, Mark Thompson, Simon Polstra, Cagkan Erbas
Venue: Journal of Signal Processing Systems (2008)

High-level performance modeling and simulation have become a key ingredient of system-level design as they facilitate early architectural design space exploration. An important precondition for such high-level modeling and simulation methods is that they should yield trustworthy performance estimations. This requires validation (if possible) and calibration of the simulation models, which are two aspects that have not yet been widely addressed in the system-level community. This article presents a number of mechanisms for both calibrating isolated model components as well as a system-level performance model as a whole. We discuss these model calibration mechanisms in the context of our Sesame system-level simulation framework. Two illustrative case studies will also be presented to indicate the merits of model calibration.
RBFN-based decentralized adaptive control of a class of large-scale non-affine nonlinear systems
Authors: Tong Zhao
Venue: Neural Computing and Applications (2008)

For a class of large-scale decentralized nonlinear systems with strong interconnections, a radial basis function neural network (RBFN) adaptive control scheme is proposed. The system is composed of a class of non-affine nonlinear subsystems, which are implicit function and smooth with respect to control input. Based on implicit function theorem, inverse function theorem and the design idea of pseudo-control, a novel control algorithm is proposed. Two neural networks are used to approximate unknown nonlinearities in the subsystem and unknown interconnection function, respectively. The stability is proved rigidly. The result of simulation validates the effectiveness of the proposed scheme.
Algorithmic mediation for collaborative exploratory search
Authors: Jeremy Pickens, Gene Golovchinsky, Chirag Shah, Pernilla Qvarfordt, Maribeth Back
Venue: Proceedings of the 31st annual international ACM SIGIR conference on Research and development in information retrieval (2008)

We describe a new approach to information retrieval: algorithmic mediation for intentional, synchronous collaborative exploratory search. Using our system, two or more users with a common information need search together, simultaneously. The collaborative system provides tools, user interfaces and, most importantly, algorithmically-mediated retrieval to focus, enhance and augment the team's search and communication activities. Collaborative search outperformed post hoc merging of similarly instrumented single user runs. Algorithmic mediation improved both collaborative search (allowing a team of searchers to find relevant information more efficiently and effectively), and exploratory search (allowing the searchers to find relevant information that cannot be found while working individually).
Modelling the radiative electromagnetic field
Authors: Mikhail B. Markov, Mikhail E. Zhukovskiy
Venue: International Journal of Computing Science and Mathematics (2008)

The radiative electromagnetic field is generated during the experiments with a radiation and is of importance for spacecrafts under sun radiation and for the radio-electronic equipment of the nuclear reactor control systems. The paper presents the developed methods of modelling the multistage process of the radiative electromagnetic field excitation. The methods are based on both deterministic technique of solving the time-dependent self-consistent problems for the Maxwell equations and statistical algorithms for modelling the ionising radiation transport in dense materials.

Authors: H. Zender, O. Martínez Mozos, P. Jensfelt, G. -J. M. Kruijff, W. Burgard
Venue: Robotics and Autonomous Systems (2008)

We present an approach for creating conceptual representations of human-made indoor environments using mobile robots. The concepts refer to spatial and functional properties of typical indoor environments. Following different findings in spatial cognition, our model is composed of layers representing maps at different levels of abstraction. The complete system is integrated in a mobile robot endowed with laser and vision sensors for place and object recognition. The system also incorporates a linguistic framework that actively supports the map acquisition process, and which is used for situated dialogue. Finally, we discuss the capabilities of the integrated system.
A Workflow-Based Access Control Framework for e-Health Applications
Authors: Giovanni Russello, Changyu Dong, Naranker Dulay
Venue: Proceedings of the 22nd International Conference on Advanced Information Networking and Applications - Workshops (2008)

In this paper, we present a framework where access rights are provided to entities on the basis of the actual task that the entities must fulfill as part of their duties. For capturing the requirements of entities' duties we use the notion of workflow. Our main aim is to provide an access control mechanism that is able to balance the competing goals of flexibility and security. As the main beneficiary of our approach we consider e-Health Applications, where flexibility and security are major requirements. We also provide an implementation of a medical case study to illustrate the framework.
Planning and scheduling in an e-learning environment. A constraint-programming-based approach
Authors: Antonio Garrido, Eva Onaindia, Oscar Sapena
Venue: Engineering Applications of Artificial Intelligence (2008)

AI planning techniques offer very appealing possibilities for their application to e-learning environments. After all, dealing with course designs, learning routes and tasks keeps a strong resemblance with a planning process and its main components aimed at finding which tasks must be done and when. This paper focuses on planning learning routes under a very expressive constraint programming approach for planning. After presenting the general planning formulation based on constraint programming, we adapt it to an e-learning setting. This requires to model learners profiles, learning concepts, how tasks attain concepts at different competence levels, synchronisation constraints for working-group tasks, capacity resource constraints, multi-criteria optimisation, breaking symmetry problems and designing particular heuristics. Finally, we also present a simple example (modelled by means of an authoring tool that we are currently implementing) which shows the applicability of this model, the use of different optimisation metrics, heuristics and how the resulting learning routes can be easily generated.
Are you moved by your social network application?
Authors: Abderrahmen Mtibaa, Augustin Chaintreau, Jason LeBrun, Earl Oliver, Anna-Kaisa Pietilainen, Christophe Diot
Venue: Proceedings of the first workshop on Online social networks (2008)

This paper studies a Bluetooth-based mobile social network application deployed among a group of 28 participants collected during a computer communication conference. We compare the social graph containing friends, as defined by participants, to the contact graph, that is the temporal network created by opportunistic contacts as owners of devices move and come into communication range. Our contribution is twofold: first, we prove that most properties of nodes, links, and paths correlate among the social and contact graphs. Second, we describe how the structure of the social graph helps build forwarding paths in the contact graph, allowing two nodes to communicate over time using opportunistic contacts and intermediate nodes. Efficient paths can be built using only pairs of nodes that are socially close (i.e. connected through a few pairs of friends). Our results indicate that opportunistic forwarding complies with the requirement of social network application.
Identifying the source of variance shifts in the multivariate process using neural networks and support vector machines
Authors: Chuen-Sheng Cheng, Hui-Ping Cheng
Venue: Expert Systems with Applications: An International Journal (2008)

Process control charts are important tools for monitoring process variation in manufacturing industries. There are many situations in which the simultaneous monitoring or control of two or more related quality characteristics is necessary. Out-of-control signals in multivariate charts may be caused by one or more variables or a combination of variables. One difficulty encountered with multivariate control charts is the interpretation of an out-of-control signal. That is, we have to determine which variable is responsible for the signal. A novel approach for identifying the source of variance shifts in the multivariate process is presented in this paper. In this study, we formulated the interpretation of out-of-control signal as a classification problem. The proposed system includes a shift detector and a classifier. The traditional generalized variance chart works as a variance shift detector. When an out-of-control signal is generated, a classifier will determine which variable is responsible for the variance shift. We consider two classifiers based on neural networks (NN) and support vector machines (SVM). We propose using subgroup data and some extracted features as predictors. The performance of the proposed system was evaluated by computing its classification accuracy. Results from simulation studies indicate that the proposed approach is a successful method in identifying the source of variance change. The results indicate that the NN-based classifier and SVM classifier have similar classification performance. An illustrative example is given to describe the applications of the proposed methods in manufacturing process control. The proposed method may facilitate the diagnosis of the out-of-control signal.

Venue: Proceedings of the First International Workshop on Knowledge Discovery and Data Mining (2008)

In order to find out the industrial characteristics and development trend of radio and TV industry in China, the developing course of this industry has been analysis from labor productivity, based on contrastive analysis and diagrammatic analysis. By comparison to three major industries, the developing rapidly and hopeful road has been exposed, and before it has not received adequate recognition to itself. In order to study the spatial distribution rule, using the spatial analysis function of GIS and spatial statistical models, quantitative analysis and qualitative evaluation on Radio and TV industry in China have been done. Then from the spatial scale, the spatial modes of this industry both on province and county scale have been studied deeply. The results show that there are certain spatial agglomerations in general for labor productivity in China. In the local region, obvious spatial associations exit too.
Towards a model for cost-benefit-analysis of quality assurance in the automotive E/E development
Authors: Nicolas F. Porta
Venue: Proceedings of the 1st international workshop on Business impact of process improvements (2008)

This paper analyzes concepts to measure benefits of quality assurance measures applied in the electric / electronics (E/E) development in the automotive domain. Therefore selected models are examined and their suitability in the given context is evaluated. Since typical models in literature do not fulfil the practical requirements, the goal is to develop an extensive cost-benefit model based on organization specific cause-and-effect chains embracing software but also hardware development aspects. In a first example, based on the experiences in a software engineering experiment with 20 students, the applicability of the defined cause-and-effect chains with their according metrics is shown. Further research aims on process simulation to ensure plausibility and case studies for the validation of the presented approach.
Implementing Multidimensional Security into OLAP Tools
Authors: Carlos Blanco, Eduardo Fernández-Medina, Juan Trujillo, Mario Piattini
Venue: Proceedings of the 2008 Third International Conference on Availability, Reliability and Security (2008)

Data Warehouses (DW) manage historical information for the decision making process and for enterprises, it is vitally important to consider security requirements from the earliest stages of the development process. OLAP tools are the most used tools for implementing and consulting DWs and it is necessary to define security measures to avoid that users can access unauthorized information by executing queries. We have created a MDA architecture for developing secure DW and in this paper, we will propose how to implement the security measures defined at upper abstraction levels using our approach into SQL Server Analysis Services 2008.

Authors: Megat Norulazmi Megat Mohamed Noor, Shaidah Jusoh
Venue: Proceedings of the 2008 Second Asia International Conference on Modelling & Simulation (AMS) (2008)

Non close loop manufacturing process, typically in the hard disk media industries rely from its inspection machine to generate production yield temporal data that can be used for future analysis. In order for an engineer to proactively perform maintenance on its process equipment and avoiding unnecessary unplanned down time, they need to be able to predict the outcome of the yield before products arrives at the inspection machine. The future prediction of the yield outcome can be achieved by visualizing the historical data pattern generated from the inspection machine, transform the data pattern and map it into machine learning algorithm for training in order to automatically generate a prediction model without the visual interpretation needs to be done by human.
A dual sequence simulated annealing algorithm for constrained optimization
Authors: Linet Ozdamar
Venue: Proceedings of the 10th WSEAS International Conference on APPLIED MATHEMATICS (2006)

We propose a dual sequence Simulated Annealing algorithm, DSAC, for solving constrained optimization problems. This approach eliminates the need for imposing penalties in the objective function by tracing feasible and infeasible solution sequences independently. We compare DSAC with a similar single sequence algorithm, PSAC, where the objective function is augmented by various penalty forms related to constraint infeasibilities. Numerical experiments show that DSAC is more effective than its counterpart PSAC in the worst and average case performances.

A VNS-based hierarchical clustering method
Authors: Chieh-Yuan Tsai, Chuang-Cheng Chiu
Venue: Proceedings of the 5th WSEAS International Conference on Computational Intelligence, Man-Machine Systems and Cybernetics (2006)

Traditional hierarchical clustering methods adopt a greedy strategy to merge objects progressively and construct a clustering dendrogram. However, their clustering quality might not be reliable because only local optimal information is referred during a dendrogram construction. To conquer the problem, this paper proposes a global optimal strategy to guide the dendrogram construction. The strategy aims to find an optimal circular traveling order that minimizes the total traveling distances for visiting all objects along the branches of the dendrogram, which is viewed as a traveling salesman problem (TSP). The TSP problem is solved using the variable neighborhood search (VNS) method because of its parameter-free advantage. Then, the clustering dendrogram is constructed based on the information provided by the order. Through our experiments, the clustering quality of our proposed method is superior to traditional hierarchical clustering methods.
