Multicriterial optimization of liquid food packaging systems

The food industry is in the crossfire of increasing pressure of competition, consumer demands, and growing importance of ecological sustainability considerations. Life cycle analysis is one of the most important methods for evaluation of environmental effects of food industrial technologies and packaging systems. During the last decades there have been an intense work to collect pieces of information on different environmental aspects of food packaging systems all over the world, but there is a considerable gap between the amount of knowledge and its practical application in decision making on the level of enterprises as well as in the process of determination of environmental protection fee. Application of modern, freely available software frameworks for life cycle analysis offers a favourable possibility for integration of environmental information into managerial and governmental decision making processes. Based on case studies, the article demonstrates the possibilities of utilisation of cumulative environmental burden indicators as well as expert decision-support systems for optimisation of product-portfolio, based on environmental considerations

DEDICATED MULTIPROCESSOR SYSTEM FOR AUTOMATIC RAIL FLAW DETECTION

An automatized ultrasonic rail flaw detection system has been developed for real-time rail flaw detection and evaluation. The whole system installed on a testing vehicle, working under rough environmental conditions must determine the internal irregularities of the rail, document them on the basis of a table containing the danger information, and immediately mark the rail in order to make easy the identification of the faulty segments for maintenance staff. During the measurement, three pairs of ultrasonic transmitters and receivers, with different orientation, scan the rail providing indirect information about the vertical section. The rail flaw detection procedure itself is a twodimensional pattern recognition problem consisting of image reconstruction, spatial filtering with thresholding and classifying phases

The particle spectrum of the Tricritical Ising Model with spin reversal symmetric perturbations

We analyze the evolution of the particle spectrum of the Tricritical Ising Model by varying the couplings of the energy and vacancy density fields. The particle content changes from the spectrum of a supersymmetric theory (either of an exact or a spontaneously broken supersymmetric theory) to the spectrum of seven particles related to the underlying E_7 structure. In the low temperature phase some of these excitations are topologically charged particles that are stable under an arbitrary variation of the parameters. The high and low temperature phases of the model are related by duality. In some regions of the two couplings there are also present false vacua and sequences of bound states. In order to study the non-integrable features of this model we employ the Form Factor Perturbation Theory and the Truncated Conformal Space Approach.Comment: 34 pages, 14 figures, text misprints correcte

Forecasting share price movements using news sentiment analysis in a multinational environment

Using a common definition we can define news analysis as the measurement of the various qualitative and quantitative elements of textual news stories. These elements include sentiment, relevance and novelty. By quantifying news stories we can gain a useful way to manipulate and use everyday information in a mathematically concise manner. In this article a framework for news analytics techniques used in finance is provided. Various news analytic methods and software are discussed, and a set of metrics is given that may be applied to assess the performance of analytics. Various directions for this field are discussed. The proposed methods can help the valuation and trading of securities, facilitate investment decision making, meet regulatory requirements, or manage risk

A migráció és a magyar migránsok jellemzői 1999-2011

In this paper we use the Hungarian Central Statistical Office’s Labour Force Survey to examine the rate of Hungarian inhabitants working abroad between 1999 and 2011. We also examine the charac teristics of this group. A break in trend can be observed in the fourth quarter of 2009 in the rate of Hungarians with a foreign workplace . The growth of the rate has accelerated since then. Working abroad – including commuting between countries – is more frequent in the group of men and in the age group between 20 and 30 years. Considering education, vocational school and university degree make working abroad the most likely but this effect does not apply the same way in different geographical regions. In more developed regions the effect of education is stronger and the odds of working abroad are the highest for people with university degree. In less developed regions vocational training increases the most the odds of working in another country. The effec t of age also differs: while in less developed regions being above the age of 40 decreases significantly the odds of working abroad, in developed regions this effect does not apply

Healthcare values and potential uses of the new Hungarian apple varieties on the basis on fruit analysis

Biological active compounds and valuable characteristics of some apple varieties and candidates were measured in our trials. Fruits of ’Rosmerta’, ’Hesztia’, ’Cordelia’ and ’Artemisz’ are recommended to enrich the Hungarian assortments for fresh consumption and choice of new tastes. Based on examined parameters it can be assumed that novel Hungarian resistant varieties are suitable for juice and fruit concentrate production, and due to high pectin content of their remaining pomace these varieties can be raw material of pectin production as well as they are also suitable for jam production mixed with other fruit species. Furthermore, functional food industrial product having high quality can be produced by using novel resistant varieties because of their high pectin and polyphenol content. Beside of their high market value their suitability for growing among orchard conditions is confi rmed by lower costs of production because of less plant protection treatments

Experimental determination of the 3^3He(α\alpha,γ\gamma)7^7Be reaction cross section above the 7^7Be proton separation threshold

The $^3$He($\alpha$,$\gamma$)$^7$Be reaction plays a major role both in the BBN producing the majority of the primordial $^7$Li, and in the pp-chain, where it is the branching point. As a few-nucleon system, this reaction is often used to validate ab-initio theoretical calculations and/or test R-matrix theory and code implementations. For the latter, experimental data in an extended energy range is of crucial importance to test the fit and extrapolation capabilities of the different codes. The $^3$He($\alpha$,$\gamma$)$^7$Be reaction cross section has been measured by several groups up to the first resonance ($E_{c.m.} \approx 3$ MeV) in the reaction. However, only one dataset exists above the $^7$Be proton separation threshold measured in a narrow energy range ($E_{c.m.} = 4.0-4.4$ MeV). In this work we extend the available experimental capture cross section database to the energy range of known $^7$Be levels. The activation method was used. The experiment was performed using a thin-window gas cell with two high-purity Al foils as entrance and exit windows. The activity of the $^7$Be nuclei implanted in the exit/catcher foil was measured by detecting the yield of the emitted $\gamma$~rays using shielded high-purity germanium detectors. New experimental $^3$He($\alpha$,$\gamma$)$^7$Be reaction cross section data were obtained for the first time in the $E_{c.m.}=4.3-8.3$ MeV energy region. The new dataset with about 0.2 MeV step covers the energy range of known levels and particle separation thresholds. No prominent structures are observer around the $^7$Be levels. The reaction cross section is slowly increasing with increasing energy. Above the $^6$Li$+p_1$ threshold, a decrease starts in the cross section trend. The overall structure of the cross section suggest a broad resonance peaking around $E_x=7.5$ MeV $^7$Be excitation energy, with a width of 8 MeV.Comment: Accepted for publication in PR
