Acceptance of future persuasive in-car interfaces towards a more economic driving behaviour
Authors: Alexander Meschtscherjakov, David Wilfinger, Thomas Scherndl, Manfred Tscheligi
Venue: Proceedings of the 1st International Conference on Automotive User Interfaces and Interactive Vehicular Applications (2009)

Measuring user acceptance to avoid system rejection by the users in pre-prototype stage of product development is of high interest for both researchers and practitioners. This is especially true when technology uses strategies of persuasion in an emotional laden environment like the car. This paper presents the results of an online survey aiming at evaluating the acceptance of future persuasive in-car interaction approaches for a more economic driving behaviour. Five different persuasive interface concepts are presented and studied towards their acceptance. The results show an overall acceptance of the system concepts and the usefulness of the presented method. We show that individual expectations of the systems' disturbance and risk have an effect on the acceptance of technology and the behavioural intention to use.
Isoline retrieval: An optimal sounding method for validation of advected contours
Authors: Peter Mills
Venue: Computers Geosciences (2009)

The study of chaotic mixing is important for its potential to improve our understanding of fluid systems. Contour advection simulations provide a good model of the phenomenon by tracking the evolution of one or more contours or isolines of a trace substance to a high level of precision. The most accurate method of validating an advected contour is to divide the tracer concentration into discrete ranges and perform a maximum likelihood classification, a method that we term, ''isoline retrieval.'' Conditional probabilities generated as a result provide excellent error characterization. In this study, a water vapour isoline of 0.001 mass-mixing-ratio is advected over five days in the upper troposphere and compared with high-resolution Advanced Microwave Sounding Unit (AMSU) satellite retrievals. The goal is to find the same fine-scale, chaotic mixing in the isoline retrievals as seen in the advection simulations. Some of the filaments generated by the simulations show up in the conditional probabilities as areas of reduced probability. By rescaling the probabilities, the filaments may be revealed in the isoline retrievals proper with little effect on the overall accuracy. Limitations imposed by the specific context, i.e., water vapour retrieved with AMSU in the upper troposphere, are discussed. Nonetheless, isoline retrieval is shown to be a highly effective technique for atmospheric sounding, showing good agreement with both European Centre for Medium-range Weather Forecasts (ECMWF) assimilation data and radiosonde measurements.
Optimization of the Spatial Interpolation for Groundwater Depth in Shule River Basin
Authors: Zhang Hua, Ma Dehai, Wang Cheng
Venue: Proceedings of the 2009 International Conference on Environmental Science and Information Application Technology - Volume 02 (2009)

To understand the spatial interpolation optimization laws of groundwater depth, two different methods of spatial interpolation are compared: (1) inverse distance weighting (IDW), (2) Ordinary Kriging (OK), using the recorded data of groundwater depth in the Shule River basin, China, in March from 2001 to 2006. The result indicates that the accuracy of the OK is the highest. After exploratory spatial analysis for groundwater data, it shows that the groundwater depth is characterized by high dispersion, with a few outliers, and a positively skewed distribution. However, data transformation reduces the variances and skewed distribution, and effectively removes various interpolation noises in the interpolation surfaces. The cross-validation results indicate that data transformation can improve accuracy of the OK.
An analysis of global edf schedulability for arbitrary-deadline sporadic task systems
Authors: Theodore P. Baker, Sanjoy K. Baruah
Venue: Real-Time Systems (2009)

Recent results on the global multiprocessor edf scheduling of sporadic task systems are, for the most part, applicable only to task systems in which each task's relative deadline parameter is constrained to be no larger than its minimum inter-arrival separation. This paper introduces new analysis techniques that allow for similar results to be derived for task systems in which individual tasks are not constrained in this manner. For tasks with deadlines greater than their minimum inter-arrival separation, two models are considered, with and without an implicit intra-task job precedence constraint. The new analyses yield schedulability conditions that strictly dominate some previously proposed tests that are generally accepted to represent the current state of the art in multiprocessor edf schedulability analysis, and permits the derivation of an improved speed-up bound.
A Wireless Sensor Network Architecture for Homeland Security Application
Authors: António Grilo, Krzysztof Piotrowski, Peter Langendoerfer, Augusto Casaca
Venue: Proceedings of the 8th International Conference on Ad-Hoc, Mobile and Wireless Networks (2009)

This paper introduces an innovative wireless sensor network architecture, which has intrinsic reliability and can therefore be used for some components of homeland security applications such as intrusion detection. The proposed architecture includes a set of communication protocols in the different layers of the model. DTSN is a transport protocol used for reliable data transfer and DSDV is a routing protocol. The distributed and reactive data storage is realized using the tinyDSM middleware. The architecture provides also security features such as data secrecy and integrity. The cipher means used for this are ECC and SkipJack which have been developed for wireless sensor networks. Our homeland security architecture has been implemented as a demonstrator using 15 MicaZ motes equipped with acoustic and passive infra red sensors. This paper provides insight into the architecture and presents the main lessons learnt from a prototype demonstrator.
An egalitarist fusion of incommensurable ranked belief bases under constraints
Authors: Salem Benferhat, Sylvain Lagrue, Julien Rossit
Venue: Proceedings of the 22nd national conference on Artificial intelligence - Volume 1 (2007)

In the last decade, several approaches have been proposed for merging multiple and potentially conflicting pieces of information. Egalitarist fusion modes privilege solutions that minimize the (local) dissatisfaction of each agent (source, expert) who is involved in the fusion process. This paper proposes useful strategies for an egalitarist fusion of incommensurable ranked belief bases under constraints. We show that the fusion process can equivalently be characterized either by means of the notion of compatible ranked bases, or by means of a Pareto-like ordering on the set of possible solutions. Lastly, rational postulates for our merging operator are studied.
Augmenting the kappa statistic to determine interannotator reliability for multiply labeled data points
Authors: Andrew Rosenberg, Ed Binkowski
Venue: Proceedings of HLT-NAACL 2004: Short Papers on XX (2004)

This paper describes a method for evaluating interannotator reliability in an email corpus annotated for type (e.g., question, answer, social chat) when annotators are allowed to assign multiple labels to a message. An augmentation is proposed to Cohen's kappa statistic which permits all data to be included in the reliability measure and which further permits the identification of more or less reliably annotated data points.
Guest Editors' Introduction: Raising the Abstraction Level of Hardware Design
Authors: Philippe Coussy, Andres Takach
Venue: IEEE Design Test (2009)

Design complexity is continually rising with the higher levels of integration implied by Moore's law. Functional complexity increases as more computation is added to SoCs and as more-complex applications are developed. Additional complexity is introduced by the need to control power consumption and to tackle challenges with respect to physical timing closure and process variations. To manage this complexity requires automation, letting designers focus on high-level design decisions that have the most effect in the implementation's quality. A higher level of hardware design abstraction also enables an effective exploration of software and hardware architectures, making high-level synthesis a cornerstone of electronic system-level design. This special issue features nine articles that the authors believe will generate interest in the use of high-level synthesis and its further development.
Towards a Global AAA Framework for Internet
Authors: Sébastien Decugis
Venue: Proceedings of the 2009 Ninth Annual International Symposium on Applications and the Internet (2009)

A common Authentication, Authorization and Accounting(AAA) framework enables communication between control structures across several interconnected organizations. It is a requirement to allow users mobility or emergence of new distributed services. The path leading to a global framework contains many obstacles, technical and political, that must be overcome to achieve new generation network features such as pervasive computing. While creating a new framework implementation focused on extensibility, we have found some issues in Diameter, the state-of-the-art AAA framework in Internet. This paper summarizes the fundamentals of a AAA architecture, then presents our implementation waaad and our findings on Diameter limitations. It shows that Diameter is suitable for AAA in the future, but some problems must be addressed first. The next phase-in our evaluation of the Diameter framework is the deployment of our implementation in a multi-realm environment, one step closer to a global AAA framework.
Phase noise - consumption trade-off in low power RF-LC-VCO design in micro and nanometric technologies
Authors: Rafaella Fiorelli, Fernando Silveira, Eduardo Peralías
Venue: Proceedings of the 22nd Annual Symposium on Integrated Circuits and System Design: Chip on the Dunes (2009)

An LC-VCO design optimization, based on the gm/ID methodology, is presented throughout this work, highlighting how, by applying all regions of inversion of the MOS transistor, the trade-off between phase noise and current consumption can be optimized for the application. Both transistor compact model equations and transistor data acquired from simulation are used to obtain gm/ID curves as well as normalized capacitances. Influence of tank elements' characteristics in the VCO performance is also discussed. Results of applying the methodology in the design of two VCOs in 0.35&mu;m and 90nm CMOS processes are described. Measurement results for the 915MHz VCO designed in 0.35&mu;m CMOS technology are also presented, obtaining a current consumption of 3mA with a phase noise (L) of --107dBc/Hz @1MHz. The 2.4GHz VCO designed in a 90nm radiofrequency technology shows a current consumption of 400&mu;A with a L of --111.4dBc/Hz @600kHz.
Measurement of Olfactory Characteristics for Two Kinds of Scent in a Single Breath
Authors: Kaori Ohtsu, Junta Sato, Yuichi Bannai, Kenichi Okada
Venue: Proceedings of the 12th IFIP TC 13 International Conference on Human-Computer Interaction: Part II (2009)

This study describes a presentation technique of scent designed for users to recognize multiple scents during a very short time period. We measured the olfactory characteristics of subjects when two kinds of scents were presented in a single breath. We defined and measured the minimum ejection interval in which subjects could discriminate the two individually emitted pulses of scent, which we term "separable detection threshold", and the minimum ejection interval in which they could specify both kinds of scents, "separable recognition threshold". Further, "response time" and "duration of scent perception" were measured. As a result, we found the duration of scent perception and the separable recognition threshold were positively correlated. Knowledge of this olfactory characteristic brings us closer to being able to provide a greater sense of realism in multimedia environments, by describing more than one object by scent at the same time as the objects are seen on screen.
Device Integration in SODA Using the Device Description Language
Authors: Chao Chen, Abdelsalam (Sumi) Helal
Venue: Proceedings of the 2009 Ninth Annual International Symposium on Applications and the Internet (2009)

The scale and pace by which the pervasive Internet is evolving today demand urgently needed solutions for a new breed of integration technology that is scalable and autonomic. Current integration technology is ad-hoc, “seasonal” and suffers from major scalability problems. In this paper, we present a novel approach for device integration based on the Service Oriented Architecture model. We present the Device Description Language (DDL) and its implementation within the Atlas sensor platform and middleware. We demonstrate DDL’s capability for describing and integrating a broad range of devices ranging from a pinhead temperature sensor to a complex device such as a personal health device. We also summarize our efforts to standardize DDL within the SODA Alliance.
The Materiality of Learning: Technology and Knowledge in Educational Practice, 1st edition
Authors: Estrid Srensen
Venue: Learning In Doing Social, Cognitive And Computational Perspectives (2009)

The field of educational research lacks a methodology for the study of learning that does not begin with humans, their aims, and their interests. The Materiality of Learning seeks to overcome this human-centered mentality by developing a novel spatial approach to the materiality of learning. Drawing on science and technology studies (STS), Estrid Srensen compares an Internet-based 3D virtual environment project in a fourth-grade class with the class's work with traditional learning materials, including blackboards, textbooks, notebooks, pencils, and rulers. Taking into account pupils' and teachers' physical bodies, Professor Srensen analyzes the multiple forms of technology, knowledge, and presence that are enacted with the materials. Featuring detailed ethnographic descriptions and useful end-of-chapter summaries, this book is an important reference for professionals and graduate or postgraduate students interested in a variety of fields, including educational studies, educational psychology, social anthropology, and STS.

Authoring Behaviour for Characters in Games Reusing Abstracted Plan Traces
Authors: Antonio A. Sánchez-Ruiz, David Llansó, Marco Antonio Gómez-Martín, Pedro A. González-Calero
Venue: Proceedings of the 9th International Conference on Intelligent Virtual Agents (2009)

Authoring the AI for non-player characters (NPCs) in modern video games is an increasingly complex task. Designers and programmers must collaborate to resolve a tension between believable agents with emergent behaviours and scripted story lines. Behaviour trees (BTs) have been proposed as an expressive mechanism that let designers create complex behaviours along the lines of the story they want to tell. However, BTs are still too complex for non-programmers. In this paper, we propose the use of plan traces to assist designers when building BTs. In order to make this approach feasible within state-of-the-art video game technology, we generate the planning domain through an extension of the component-based approach, a widely used technique for representing entities in commercial video games.
Comparison of p control charts for low defective rate
Authors: Hsiuying Wang
Venue: Computational Statistics Data Analysis (2009)

It is well known that the conventional p control chart constructed by the normal approximation for the binomial distribution suffers a serious inaccuracy in the monitor process when the true rate of nonconforming items is small. A similar problem also arises in the binomial confidence interval estimation. Adjusted confidence intervals are established in the literature to improve the coverage probability when the binomial proportion is small. In this paper, a new p control chart based on an adjusted confidence interval is established, which can substantially improve the existing control charts when the nonconforming rate is small.

Together these contributions will be an invaluable tool for graduate students and researchers looking forward to keeping up to date with the latest developments in rigorous approaches to software development.
The quest for a killer app for opportunistic and delay tolerant networks: (invited paper)
Authors: Anders Lindgren, Pan Hui
Venue: Proceedings of the 4th ACM workshop on Challenged networks (2009)

Delay Tolerant Networking (DTN) has attracted a lot of attention from the research community in recent years. Much work have been done regarding network architectures and algorithms for routing and forwarding in such networks. At the same time as many show enthusiasm for this exciting new research area there are also many sceptics, who question the usefulness of research in this area. In the past, we have seen other research areas become over-hyped and later die out as there was no killer app for them that made them useful in real scenarios. Real deployments of DTN systems have so far mostly been limited to a few niche scenarios, where they have been done as proof-of-concept field tests in research pro jects. In this paper, we embark upon a quest to find out what characterizes a potential killer applications for DTNs. Are there applications and situations where DTNs provide services that could not be achieved otherwise, or have potential to do it in a better way than other techniques? Further, we highlight some of the main challenges that needs to be solved to realize these applications and make DTNs a part of the mainstream network landscape.
Two-Way Analysis of High-Dimensional Collinear Data
Authors: Ilkka Huopaniemi, Tommi Suvitaival, Janne Nikkilä, Matej Orešič, Samuel Kaski
Venue: Proceedings of the European Conference on Machine Learning and Knowledge Discovery in Databases: Part I (2009)

We present a Bayesian model for two-way ANOVA-type analysis of high-dimensional, small sample-size datasets with highly correlated groups of variables. Modern cellular measurement methods are a main application area; typically the task is differential analysis between diseased and healthy samples, complicated by additional covariates requiring a multi-way analysis. The main complication is the combination of high dimensionality and low sample size, which renders classical multivariate techniques useless. We introduce a hierarchical model which does dimensionality reduction by assuming that the input variables come in similarly-behaving groups, and performs an ANOVA-type decomposition for the set of reduced-dimensional latent variables. We apply the methods to study lipidomic profiles of a recent large-cohort human diabetes study.
Towards an H-Mode for highly automated vehicles: driving with side sticks
Authors: Martin Kienle, Daniel Damböck, Johann Kelsch, Frank Flemisch, Klaus Bengler
Venue: Proceedings of the 1st International Conference on Automotive User Interfaces and Interactive Vehicular Applications (2009)

The increasing traffic volume confronts the road user with a challenging task. The high number of traffic deaths might not be reducible with passive safety alone. However systems that actively influence the guidance of vehicles, like assistance and automation systems, can make a difference towards higher safety, comfort and efficiency. Some of these systems completely take over single subtasks like speed or distance control. This, in turn can lead to effects like "out of the loop", where the driver withdraws from the actual task and even stops monitoring. In order to realize a safe automation system, the project H-Mode follows an approach where both, driver and assistance system are simultaneously affecting the vehicle, whereby the operator is kept in the loop and active. Moreover a haptic-multimodal communication between driver and automation is established by using active interfaces. Regarding this communication alternative control elements, especially two dimensional ones have to be considered. The study presented in this paper compares conventional interfaces (steering wheel and pedals) with different configurations of an active side stick. It is shown, that two dimensional elements have the potential to combine the driver-automation communication with acceptable drivability.
Injection Process Analysis and Mold Manufacturing for Telephone Cover
Authors: Weihua Kuang, Zikai Xue
Venue: Proceedings of the 2009 International Conference on Measuring Technology and Mechatronics Automation - Volume 02 (2009)

In injection process, many factors affect the molding process and the final quality of the parts. The method of traditional mold design is relied on the designer’s experience, and it can be time-consuming and expensive. With the help of CAE systems, designers can reduce costly trial-and-error loops and shorten development cycle, and correctly solve production problems on material property, product design, and mold design. The paper introduced the application of MoldFlow in injection molding development of the telephone cover. Best injection location is attained. Fill time, weld lines, air trips, clamp force, pressure at end of fill, and pressure at injection location are deeply studied. The numerical simulation corresponds well with practical process. The simulation provides scientific and valuable injection process information and helps engineers to take right decisions when they develop the tools. At last, the mold for telephone is designed, and the CNC machining of the mold cavity is programmed by UG NX software.

G is a König-Egervá ry graph provided $\alpha(G)+\mu (G)=\left\vert V(G)\right\vert $, where μ(G) is the size of a maximum matching and ¿(G) is the cardinality of a maximum stable set,[2],[21].S is a local maximum stable set of G, and we write S ¿ ¿(G), if S is a maximum stable set of the subgraph induced by S ¿ N(S), where N(S) is the neighborhood of S,[11]. Nemhauser and Trotter Jr. proved that any S ¿ ¿(G) is a subset of a maximum stable set of G,[19].In this paper we demonstrate that if S ¿ ¿(G), the subgraph H induced by S ¿ N(S) is a König-Egerváry graph, and M is a maximum matching in H, then M is a local maximum stable set in the line graph of G.
