Volume: 530

Page Range: 45-57

Description:

It is an significant task to qualify and rank residential buildings based on various priority aspects and to make optimum allocation of the material resources available for the renewal of the buildings.To this end a model based on fuzzy logic was prepared. To construct and to test this model many detailed technical-static expert reports were available all related to a stock of residential buildings in Budapest. Based on this report a database was created. With the help of this database a model was prepared, calculating a so-called status characteristic value between 0 and 1 on the basis of the structures and status of the buildings. For this calculation a fuzzy singleton signature model was prepared. Based on this a hierarchy can be set up related to the stock of buildings, which is suitable for supporting the decision making on intervention. The model was examined by using the created database. Membership values characterising the status of the load-bearing structures-were defined on the basis of the deterioration of the structures. In this chapter a new method for the determination of the membership values is described, which in addition to the deteriorations of the structures takes into account other parameters of the structures, and the impact exerted on the quality of the structure, too. The method is suitable for the determination of the membership values of all primary and secondary structures. As an example the membership values of the foundation structures of the buildings in the database were defined and the results were analysed. The method was elaborated by the use of "real fuzzy values" (R-fuzzy sets), an extension of the concept of classic fuzzy sets, the former being suitable for simultaneously taking into account various aspects. © Springer International Publishing Switzerland 2014.

The determination of the bitrate on twisted pairs by mamdani inference method

Ferenc Lilik L. T. Kóczy

Publication Name: Studies in Computational Intelligence

Publication Date: 2014-02-03

Volume: 530

Issue: Unknown

Page Range: 59-74

Description:

There are several methods for predicting the available maximal data transfer rate on dedicated telecommunication connections. This chapter presents some generally used techniques for prediction and some results of a Mamdani-type fuzzy reasoning system that is used in a telecommunication research aimed to create new predicting methods. At the end of the article the results of various methods are compared. All presented techniques are used for evaluation of the twisted-pair based local loops of the telecommunication access networks. © Springer International Publishing Switzerland 2014.

Intelligent robot cooperation with fuzzy communication

Claudiu Radu Pozna Áron Ballagi L. T. Kóczy

Publication Name: Studies in Computational Intelligence

Publication Date: 2014-02-03

Volume: 530

Issue: Unknown

Page Range: 185-197

Description:

Designing the decision-making engine of a robot which works in a collaborative team is a challenging task. This is not only due to the complexity of the environment uncertainty, dynamism and imprecision, but also because of the coordination of the team has to be included in this design. The robots must be aware of other robots' actions in order to cooperate and to successfully achieve their common goal. In addition, decisions must be made in real-time and using limited computational resources. In this chapter we propose some novel algorithms for action selection in ambiguous tasks where the communication opportunities among the robots are very limited. © Springer International Publishing Switzerland 2014.

Molecular dynamics simulation of carbon nanostructures: The D5h C70 fullerene

Ibolya Zsoldos István László

Publication Name: Physica E Low Dimensional Systems and Nanostructures

Publication Date: 2014-02-01

Volume: 56

Issue: Unknown

Page Range: 422-426

Description:

Molecular dynamics calculations can reveal the physical and chemical properties of various carbon nanostructures or can help to devise the possible formation pathways. In our days the most well known carbon nanostructures are the fullerenes and the nanotubes. They can be thought of as being formed from graphene sheets, i.e. single layers of carbon atoms arranged in a honeycomb lattice. Usually the nature does not follow the mathematical constructions. An ideal nanotube can be thought of as a hexagonal network of carbon atoms that has been rolled up to make a cylinder. There is not any theory of carbon nanotube formation which is based on this construction. Although the first time the C60 and C70 were constructed by laser irradiated graphite, the fullerene formation theories are based on various fragments of carbon chains, and networks of pentagonal and hexagonal rings. In the present article different initial patterns will be given for the formation of the C70 fullerene with D5h symmetry. The desired final structures are obtained in tight-binding molecular dynamics calculations. © 2013 Published by Elsevier B.V.

Nonlinear moving horizon predictive control of ground vehicles

Gyorgy Max Bela Lantos

Publication Name: Cinti 2014 15th IEEE International Symposium on Computational Intelligence and Informatics Proceedings

Publication Date: 2014-01-30

Volume: Unknown

Issue: Unknown

Page Range: 421-426

Description:

The paper deals with the approximately time-optimal control of automatically driven cars modeled with gear shift as discrete control input beside the continuous ones in a path between two path boundaries. The path boundaries are defined by their corner points that may be the result of image processing in real time or prescribed in advance. The path is divided into sections for which separate optimum control problems are solved in a nonlinear moving horizon predictive control (NMHPC) fashion increasing the semi-online character of the approach. In each section the problem can be formulated as a mixed-integer optimal control problem (MIOCP). The resulting MIOCP is solved by reformulating it to static mixed-integer nonlinear program (MINLP) using time discretization and direct multiple shooting method. Non-commercial open software packages are applied that substantially use the gradients of the objective function and the Jacobians of the constraints exploiting sparsity. The elaborated method can be applied both for combustion engine and electric driven cars. It can also form the basis to generate an offline database of a central general collision avoidance system (CAS) for varying path parameters on a grid which can further support real time applications.

Jung - Kerényi - Pauli and the cognitive individuation Part II: Model reconstructions for cognitive individuation

Peter Varlaki Péter Baranyi

Publication Name: 5th IEEE International Conference on Cognitive Infocommunications Coginfocom 2014 Proceedings

Publication Date: 2014-01-23

Volume: Unknown

Issue: Unknown

Page Range: 637-646

Description:

In this part of the paper a more differentiated system structure and dynamic process can be discussed to Jung's cognitive 'individuation process' suggested by W. Pauli in a partly conscious and partly unconscious cooperation with Jung. Furthermore, it can be linked to the dynamic systems of the Proto-Kabbala's Sephiroth system and the approximation of the 'dynamic processes' of the Eleusinian Mysteries and similar mythologems described by Kerényi in a 'system-theoretical manner', taking into account the modern 'control paradigm', as well.

Publication Name: 5th IEEE International Conference on Cognitive Infocommunications Coginfocom 2014 Proceedings

Page Range: 617-628

Description:

The second part of the paper deals with the Jung-Kerényi -Pauli dominantly unconscious 'cooperation' on the basis of the synchronistic background in the years 1954-57.The main patterns of the 'especial communication' is based also on the structure and meaning of the 'Eleusinian mysteries' together with the Perseus mythologem and its possible relation to the 'Leviathan myth' exploring as an extended 'dynamic hermeneutical system'.

Using Fuzzy Cognitive Map approach to model the casual relationships in stakeholder management at companies

Miklós F. Hatwágner Dalia Susniene Adrienn Buruzs András Torma L. T. Kóczy

Publication Name: 5th IEEE International Conference on Cognitive Infocommunications Coginfocom 2014 Proceedings

Publication Date: 2014-01-23

Volume: Unknown

Issue: Unknown

Page Range: 121-124

Description:

The aim of this paper is to investigate the operation of a Stakeholder Relationship Management System (SRMS) as a method for business management and project support by fuzzy approach. The criteria defined in connection with the SRMS will be modelled by using the Fuzzy Cognitive Map (FCM) approach in order to define the causality and weights of interconnections between the factors and to support decision making in that way.
