Strong stability preserving explicit linear multistep methods with variable step size

Yiannis Hadjimichael Adrián Németh David I. Ketcheson Lajos Lóczi

Publication Name: SIAM Journal on Numerical Analysis

Publication Date: 2016-01-01

Volume: 54

Issue: 5

Page Range: 2799-2832

Description:

Strong stability preserving (SSP) methods are designed primarily for time integration of nonlinear hyperbolic PDEs, for which the permissible SSP step size varies from one step to the next. We develop the first SSP linear multistep methods (of order two and three) with variable step size, and prove their optimality, stability, and convergence. The choice of step size for multistep SSP methods is an interesting problem because the allowable step size depends on the SSP coefficient, which in turn depends on the chosen step sizes. The description of the methods includes an optimal step-size strategy. We prove sharp upper bounds on the allowable step size for explicit SSP linear multistep methods and show the existence of methods with arbitrarily high order of accuracy. The effectiveness of the methods is demonstrated through numerical examples.

Evaluation of response times on a touch screen using stereo panned speech command auditory feedback

Hunor Nagy György Wersényi

Publication Name: Lecture Notes in Computer Science Including Subseries Lecture Notes in Artificial Intelligence and Lecture Notes in Bioinformatics

Publication Date: 2016-01-01

Volume: 9811 LNCS

Issue: Unknown

Page Range: 279-286

Description:

User interfaces to access mobile and handheld devices usually incorporate touch screens. Fast user responses are in general not critical, however, some applications require fast and accurate reactions from users. Errors and response times depend on many factors such as the user’s abilities, feedback types and latencies from the device, sizes of the buttons to press, etc. We conducted an experiment with 17 subjects to test response time and accuracy to different kinds of speech-based auditory stimuli over headphones. Speech signals were spatialized based on stereo amplitude panning. Results show significantly better response times for 3 directions than for 5, as well as for native language compared to English, and more accurate judgements based on the meaning of the speech sounds rather than their direction.

Minkowski's inequality based sensitivity analysis of fuzzy signatures

Ádám Bukovics István Harmati L. T. Kóczy

Publication Name: Journal of Artificial Intelligence and Soft Computing Research

Publication Date: 2016-01-01

Volume: 6

Issue: 4

Page Range: 219-229

Description:

Fuzzy signatures were introduced as special tools to describe and handle complex systems without their detailed mathematical models. The input parameters of these systems naturally have uncertainties, due to human activities or lack of precise data. These uncertainties influence the final conclusion or decision about the system. In this paper we discuss the sensitivity of the weigthed general mean aggregation operator to the uncertainty of the input values, then we analyse the sensitivity of fuzzy signatures equipped with these aggregation operators. Finally, we apply our results to a fuzzy signature used in civil enginnering.

Uncertainty of the Od Matrix's Estimation in Urban Public Transport

Balázs Horváth

Publication Name: Transportation Research Procedia

Publication Date: 2016-01-01

Volume: 14

Issue: Unknown

Page Range: 1716-1722

Description:

The key of the planning of public transport systems is the accurate prediction of the traffic load which requires a well-functioning assignment method and reliable passenger data (i.e. time-dependent OD matrix). The paper two years ago at TRA2014 was started with this idea. Since that time the procedure was improved and real network test was performed. Based on the experiences of the real network tests several new improvements were implemented. This paper shows the newest results with the previously described method and search for connection between network structure and certainty together with sample size.

On the sensitivity of weighted general mean based type-2 fuzzy signatures

István Harmati L. T. Kóczy

Publication Name: Lecture Notes in Computer Science Including Subseries Lecture Notes in Artificial Intelligence and Lecture Notes in Bioinformatics

Publication Date: 2016-01-01

Volume: 9692

Issue: Unknown

Page Range: 206-218

Description:

Fuzzy signatures offer a possible way of describing, modeling and analysing of complex systems, when the exact mathematical model is not known or too difficult to handle. In these cases the input values have uncertainties, due to lack of knowledge or human activities. These uncertainties have influence on the final decision about the system. The uncertainties are taken into consideration as fuzzy sets, for example representing the uncertainty of a linguistic variable. In this paper we discuss the input sensitivity of type-2 weighted general mean aggregation operator and fuzzy signatures which are equipped with general means as aggregation operators.

Integrated urban air pollution dispersion modelling framework and application in air quality prediction of the city of győr

No authors available

Publication Name: HARMO 2016 - 17th International Conference on Harmonisation within Atmospheric Dispersion Modelling for Regulatory Purposes, Proceedings

Publication Date: 2016-01-01

Volume: 2016-May

Issue:

Page Range: 410-414

Description:

Model accuracy versus model running time - urban air pollution dispersion modellers have to balance between them when selecting models to be implemented. CFD based models seem to be the best candidates for an accurate model that can be validated at urban scale at highest level on the price of a longer running time. In this paper we shall introduce 3DAirQC software framework which addresses a portable and validated CFD model for air quality prediction and control.

Energy-efficient Operation of GSM-connected Infrared Rodent Sensor

Gábor Paller Gábor Élo

Publication Name: Sensornets 2016 Proceedings of the 5th International Confererence on Sensor Networks

Publication Date: 2016-01-01

Volume: Unknown

Issue: Unknown

Page Range: 37-44

Description:

Camera sensors have been deployed in the agriculture for various use cases. Most of the applications tried to infer the health and development of the plants based on image data in different wavelength domains. In this paper, we present our research of rodent population estimation with infrared camera sensors. The usual camera sensor applications in the agricultural domain are quite simple from the sensor architecture point of view as the environment rarely changes. Image capture/transmission at preconfigured moments is usually enough. Rodents move quickly so the sensor must be able to capture images with low capture time interval. As the data link to the server backend is relatively slow, this fast capture rate may require image processing capability in the sensor. The paper analyzes the effects of such an image processing capability, in particular the power consumption trade-offs. Inadequate power management support of the selected embedded Linux platforms is identified as a problem and proposals are made for improvement.
