Modelling twofold uncertainty in the condition assessment of residential buildings using interval valued fuzzy signatures

Ádám Bukovics István Harmati L. T. Kóczy

Publication Name: 2016 IEEE Symposium Series on Computational Intelligence Ssci 2016

Publication Date: 2017-02-09

Volume: Unknown

Issue: Unknown

Description:

In this study we will describe an intervention decision-support method related to residential buildings, which is modelling the condition of buildings based on linguistic expert opinions so that it is capable of taking into consideration the uncertainties included in the expert opinions. Fuzzy signature-based model is used, wherein the uncertainties are integrated into the system by applying interval valued fuzzy sets, as well as linguistic hedges. The result will be a fuzzy set for each building, describing the condition of the whole building, specify the bourdary values between which the condition of the building may fall.

Characterization of the level sets for interactive additions

Lucian Coroianu Robert Fuller

Publication Name: Cinti 2016 17th IEEE International Symposium on Computational Intelligence and Informatics Proceedings

Publication Date: 2017-02-07

Volume: Unknown

Issue: Unknown

Page Range: 35-40

Description:

In this paper, on the set of unimodal fuzzy numbers, first we prove that under some minimal assumptions, it suffices to consider only those joint possibility distributions that satisfy that the left/right side of the fuzzy number generated by the interactive addition based on the given joint possibility distribution, is obtained by evaluating only the left/right side of the summands. Then, we will obtain a representation theorem for the level sets of this interactive addition in terms of the level sets of the summands. These results generalize corresponding results for the special case of triangular-norm-based additions.

Page Range: 151-156

Description:

Concerning the increasing demand for intelligent and efficient urban vehicle systems with low cost maintainability and high passenger comfort, reliable methods are needed to model and to evaluate the imposed performances. The measurements, vibrations emerging on the wheels and the body, that has ben taken on a city bus are analyzed in the frequency domain. In this paper a parametric spectral analysis (AR/ARMA method) of the suspension system of a commercial city bus is presented. The goal of the analysis is to find the right structure for the systems. Parametric methods used in this paper justify and extend the results obtained by non-parametric ones and provide more accurate results for vibration analysis. One of the main conclusions of the investigations is that the quarter-car model structure based on first principles does not reflect the true frequency domain behavior of the system. Thus the identification of the physical model must be complemented with a suitable uncertainty modeling and classification.

Non-simplex enclosing polytope generation concept for Tensor Product model transformation based controller design

Description:

In polytopic model-based controller synthesis, the vertices of the model determine the achievable performance characteristics. This paper introduces a new concept, that allows for the sophisticated construction of non-simplex enclosing polytopes. The non-simplex structures in general, have much better descriptor properties than the simplex one that leads to less conservative synthesis. The paper demonstrates the workflow of controller design for a nonlinear system through the example of the TORA (Translational Oscillator with a Rotational Actuator) system. The numerical results clearly show that the proposed approach is capable of excluding non-stabilizable regions located between the exact convex hull and the enclosing simplex. The non-simplex polytope leads to an increased number of vertices but it practically does not influence the viability of Tensor-Product (TP) formalization and the feasibility of controller design while the achievable control performance can be improved significantly.

Assessment of the remaining life of bituminous layers in road pavements

Kálmán Adorjányi

Publication Name: TEM Journal

Publication Date: 2017-02-01

Volume: 6

Issue: 1

Page Range: 64-70

Description:

In this paper, a mechanistic-empirical approach is presented for the assessment of bearing capacity condition of asphalt pavement layers by Falling Weight Deflectometer measurements and laboratory fatigue tests. The bearing capacity condition ratio was determined using past traffic data and the remaining fatigue life which was determined from multilayer pavement response model. The traffic growth rate was taken into account with finite arithmetic and geometric progressions. Fatigue resistance of layers' bituminous materials was obtained with indirect tensile fatigue tests. Deduct curve of condition scores was derived with Weibull distribution.

Description:

In vehicle and robot navigation low-level tasks such as path planning, obstacle avoidance and autonomous operation are extensively studied nowadays. Most of these task require map building. In this paper a map representation is discussed with the focus for the singular domain of our Neobotix MP500 mobile robot. Among others the state of the art map building techniques will be introduced such as topological map, line map, landmark-based map and of course in more detail the occupancy grid based map. The probabilistic representation of the occupancy grid will be examined as a map building problem for the given mobile robot.

Description:

Tactile and haptic devices can be used to control and interact with a wide range of systems, including games, virtual environments and assistive technologies. Although many psychophysical studies have measured thresholds of human sensory capabilities for interpreting haptic and tactile feedback, relatively little is known about the precision with which we are able to guide the behavior of a system based on kinesthetic and myoelectric gestures. A broad study of the latter problem is important, especially now that a number of devices have appeared-such as the Leap Motion Controller and the Myo armband-which enable humans to use finger, hand and arm gestures to interact with the digital world. This paper provides a broad overview on the topic, and reports a set of preliminary experiments on the extent to which the Myo armband can be used to control auditory feedback in real time. Test results are evaluated based on a Bayesian statistical model of an empirical (but for the most part, unambiguous) performance scale. The goal is to investigate ways in which visually impaired users could use the Myo to control the output of an assistive technology.

Comparing the aggregation capability of the MPT communications library and multipath TCP

Akos Kovacs

Publication Name: 7th IEEE International Conference on Cognitive Infocommunications Coginfocom 2016 Proceedings

Publication Date: 2017-01-03

Volume: Unknown

Issue: Unknown

Page Range: 157-161

Description:

The MPT network layer multipath communication library-which was proposed to be a possible new basis for the future cognitive info-communication-is capable to use multiple communication channels to create an UDP tunnel which uses GRE tunnel protocol. On the other hand, Multipath TCP uses a special kernel module which creates multiple TCP sub-flows to aggregate network throughput. In this paper we used twelve 100Mbps speed channels to compare the aggregation capabilities of these two multipath communication techniques. Different scenarios were used: we measured both IPv4 and IPv6 as underlying and encapsulation protocols. In all cases, we used one to twelve channels to measure the aggregation capabilities with the iperf network measurement tool and also with HTTP download.

Page Range: 455-468

Description:

In the paper we attempt to present the same in a very beautiful and uniquely interesting picture of the Hortus Deliciarum, with St. Andrew in the leading role, representing St. John the Baptist. We compare the meaning system and the numerical structure of this the Hortus Deliciarum image to the Pala d'Oro's beautiful and unique enamel of hidden meaning, depicting the presentation of the child Christ in the 'Temple.'. On tha basis of this interpretation and comparison it can be considered as a historical background of the Aquarius mythologem and its Jung-Pauli kinds of imagination and interpretation.
