Selective heating of different grain parts of wheat by microwave energy

E. Szijjártó A. J. Kovács E. Pallai-Varsányi M. Neményi

Publication Name: Advances in Microwave and Radio Frequency Processing Report from the 8th International Conference on Microwave and High Frequency Heating

Publication Date: 2006-01-01

Volume: Unknown

Issue: Unknown

Page Range: 312-320

Description:

The aim of author's research work was to investigate the effect of process parameters and microwave heat treatment condition on the inactivation of &-amylase enzyme being in wheat grains, responsible for decomposition of starch molecules without considerable damage of the gluten content. The task was furthermore to clear up the possibilities of selective moistening of the different wheat grain parts containing the &-amylase enzyme and the valuable gluten protein. For checking the results Magnetic Resonance Imaging method was used. © Springer-Verlag Berlin Heidelberg 2006.

Classification of time series via wavelet subband analysis using support vector machine classifier

Balázs Benyó B. Paláncz

Publication Name: Periodica Polytechnica Electrical Engineering

Publication Date: 2006-01-01

Volume: 50

Issue: 1-2

Page Range: 129-140

Description:

An improved feature extraction method has been developed for classification and identification of time series, in case of the number of the experiments are considerably less than that of the samples in time series. The method based on the subband analysis of the wavelet transformation of the time signals, provides lower dimension feature vectors as well as much more robust kernel-based classifier than the traditional wavelet-based feature extraction method does. The application of this technique is illustrated by the classification of cerebral blood flow oscillation using support vector classifier with Gaussian kernel. The computations were carried out with Mathematica 5.1 and its Wavelet Application.

Laser powder deposition of tool steels: Strategies leading to homogeneous parts

L. Costa T. Reti R. Vilar

Publication Name: Materials Science Forum

Publication Date: 2006-01-01

Volume: 514-516

Issue: PART 1

Page Range: 739-743

Description:

The microstructure and properties of tool steel parts built by laser powder deposition (LPD) depend considerably on the build-up strategy and on the processing parameters used. This dependence can lead to inconsistent results which may limit the widespread acceptance of LPD. There is, thus, a need for efficient process optimisation tools that take into consideration the complex phase transformations that may occur during the part build-up process and their effect on final properties. A model coupling finite element heat transfer calculations with transformation kinetic theory has been developed, which allows the microstructure and property distributions in parts produced by LPD to be predicted. Application of this model to the deposition of tool steels not only explains the origin of the heterogeneous distribution of properties usually mentioned in the literature but also allows designing build-up strategies that consistently lead to homogeneous, high quality parts. Its application to the study of the influence of substrate pre-heating and idle time between the deposition of consecutive layers is illustrated in the present paper.

Non-associative fuzzy flip-flop with dual set-reset feature

Rita Lovassy L. T. Koczy

Publication Name: Sisy 2006 4th Serbian Hungarian Joint Symposium on Intelligent Systems

Publication Date: 2006-01-01

Volume: Unknown

Issue: Unknown

Page Range: 289-299

Description:

J-K flip-flops are the most general elementary units in sequential digital circuits. By extending Boolean operations to their respective fuzzy counterparts various fuzzy flipflops (F3) can be defined. Because of the axiomatic properties of fuzzy operations are considerably weaker then the properties satisfied by Boolean lattices, the minterm and maxterm type definitions of the same F3 are as a rule not equivalent. In former work we found a unique exception where simulation investigations lead to identical results for all parameter combinations examined. The base of this unique F3 is a pair of non-associative fuzzy connectives. In this paper the exact proof is given for the identity of the two definitions, i.e., for the uniqueness of the definition of this special non-associative F3.

Expanded scope of traffic-flow analysis: Entity flow-phase analysis for rapid performance evaluation of enterprise process systems

No authors available

Publication Name: ESM 2006 - 2006 European Simulation and Modelling Conference: Modelling and Simulation 2006

Publication Date: 2006-01-01

Volume:

Issue:

Page Range: 94-98

Description:

This paper describes entity-flow phase analysis (EFA) which is a method for fast performance analysis of organisational process systems. EFA, similarly to traffic-flow analysis for communication systems (TFA), uses the combined approach of simulation and numerical methods. In simulation projects initiated to support the design of Information and Communication Technology (ICT) system and Business Process (BP) system in an organisation the parallel analysis of different systems may be efficient. EFA is a promising evaluation method to be applied for systems with determined BP and ICT subsystems in an organisational environment.

Cognitive psychological structure of education and research in geotechnics

Publication Name: Proceedings of the 16th International Conference on Soil Mechanics and Geotechnical Engineering: Geotechnology in Harmony with the Global Environment

Publication Date: 2005-12-01

Volume: 4

Issue:

Page Range: 2859-2862

Description:

Post secondary education provides an introduction to models, and develops model selection and application skills. Recent developments in cognitive psychology offer good possibilities for differentiating between levels of knowledge. It is prudent to define four levels of preparation in the technical-engineering professions, particularly in their relationship to models. As a conclusion, it turns out that professional geotechnicians are required to have MSc level of competency. The approach also yields answers to some debated questions of modelling and solving geotechnical problems in the framework of engineering mechanics.
