Authors: Deak Gabriel , Curran Kevin , Condell Joan , Deak Daniel , Kiedrowski Piotr 
Published: April 2013

Abstract
The holy grail of tracking people indoors is being able to locate them when they are not carrying any wireless tracking devices. The aim is to be able to track people just through their physical body interfering with a standard wireless network that would be in most peoples home. The human body contains about 70% water which attenuates the wireless signal reacting as an absorber. The changes in the signal along with prior fingerprinting of a physical location allow identification of a person’s location. This paper is focused on taking the principle of Device-free Passive Localisation (DfPL) and applying it to be able to actually distinguish if there is more than one person in the environment. In order to solve this problem, we tested a Support Vector Machine (SVM) classifier with kernel functions such as Linear, Quadratic, Polynomial, Gaussian Radial Basis Function (RBF) and Multilayer Perceptron (MLP), and a Probabilistic Neural Network (PNN) in order to detect movement based on changes in the wireless signal strength.

Published: April 2013

Abstract
The paper presents hybrid anomaly detection preprocessor for SNORT IDS - Intrusion Detection System [1] base on statistical test and DWT - Discrete Wavelet Transform coefficient analysis. Preprocessor increases functionality of SNORT IDS system and has complementary properties. Possibility of detection network anomalies is increased by using two different algorithms. SNORT captures network traffic features which are used by ADS (Anomaly Detection System) preprocessor for detecting anomalies. Chi-square statistical test and DWT subband coefficients energy values are used for calculating of normal network traffic profiles. We evaluated proposed SNORT extension with the use of test network.

Published: April 2013

Abstract
A new approach to the liver segmentation from 3D images is presented and compared to the existing methods in terms of quality and speed of segmentation. The proposed technique is based on 3D deformable model (active surface) combining boundary and region information. The segmentation quality is comparable to the existing methods but the proposed technique is significantly faster. The experimental evaluation was performed on clinical datasets (both MRI and CT), representing typical as well as more challenging to segment liver shapes.

On a Real-Time First-Order Difference Evaluation
Authors: Ostalczyk Piotr , Duch Piotr 
Published: April 2013

Abstract
A subject of this paper is a real-time evaluation of the first-order backward difference of a measured signal with noise. It is wellknown that a difference evaluation strongly increase a noise amplitude so the signal prefiltering is necessary. A very short review of practically used filters is given. To perform the pre-filtering operation one mainly apply linear filters characterized by their impulse response shape: finite impulse response (FIR) and infinite impulse response (IIR). To enhance the filtering operation one successfully apply so called adaptive filters and these described by non-linear characteristics. In this paper a simple non-linear filtering algorithm is proposed and examined in the first-order backward difference of a measured signal.

Authors: Korohoda Przemysław , Grabska-Chrząstowska Joanna 
Published: April 2013

Abstract
In the paper an experiment is described, that was designed and conducted to verify hypothesis that artificial neuron with sigmoidal activation function can efficiently solve the task of logistic regression in the case when the explaining variable is one-dimensional, and the explained variable is binomial. Computations were performed with 12 sets of statistical parameters, assumed for the generation of 65356 sets of data in each case. Comparative analysis of the obtained results with use of the reference values for the regression coefficients indicated that the investigated neuron can satisfactory perform the task, with efficiency similar to that obtained with classical logistic regression algorithm, when the teaching sets of input data, corresponding with output values 0 and 1, do not allow for simple separation. Moreover, it has been discovered that the simple formulas estimating the statistical distributions parameters from the samples, offer statistically superior assessment of the regression coefficient parameters.

Published: April 2013

Abstract
The capability of a genotype to achieve acceptable yield over a broad range of sub-optimum and suitable conditions is extremely imperative. Late planting and end-season drought stress are two main factors limiting wheat yield in northwest of Iran. In a 2-year field experiment at Miandoab, Iran, the ability of several selection indices to identify drought resistant genotypes under different sowing dates and moisture conditions were evaluated. Six genotypes of differing response to water scarcity were planted at 20-d intervals on three dates from 11 October to 20 November. Drought resistance indices were utilized on the basis of grain yield under end-season drought (Ys) and normal (YN) conditions. Evaluation of MP, HARM, GM, STI, TOL, SSI, RDI, YSI and Yr indicated that late sowing (20 Nov) significantly decreased drought tolerance in all investigated genotypes. However, yield comparisons under normal and terminal drought stress conditions revealed that promising lines (C-81-4, C-81- 10, C-81-14 and C-82-12) had better performance than local checks (Zarrin and Alvand). Furthermore under both moisture conditions C-81-10 genotype had the greatest grain yield. Based on drought indices like as MP, GMP, STI and HARM C-81-10 genotype introduced as the most tolerant genotype to end-season drought stress. Grain yield showed a positive and significant correlation with HARM, GMP, MP, STI and YI indices were more efficient for recognizing high performance genotypes under different sowing dates and diverse moisture stress.

Published: April 2013

Abstract
An experiment was carried out at the Agronomic Research Area, University of Agriculture, Faisalabad to assess the agro-economic performance of two maize hybrids (SIPRA-4444 and TS- 13) under five different sowing patterns viz. ridge sowing 60 cm apart rows, bed sowing 60 cm apart rows, 60 cm apart single row strips, 90 cm apart double row strips and 120 cm apart triple row strips. The results indicated that the hybrids and the sowing patterns had a significant influence on the grain yield of maize. SIPRA-4444 produced maximum grain yield (6.02 tha-1) as compared to TS-13 (5.80 tha-1). Among the planting methods, ridge sowing produced highest grain yield (7.13 t ha-1). The interactive effect of hybrids and sowing methods showed that the hybrid SIPRA - 4444 produced maximum yield when it was sown on 60 cm apart ridges. From economic point of view, maximum net income of Rs. 114172 and benefit to cost ratio of (2.37) was obtained when the hybrid SIPRA-4444 was sown on 60 cm spaced ridges.

Published: April 2013

Abstract
In order to determine the effects of different fertilization level of zinc sulphate and plant density on the breakage susceptibility of triticale seeds an experiment was conducted during 2011 growing season, at the experimental research station of Lorestan University, Iran. A factorial experiment was conducted with 3×3 treatments and three replications in a completely randomized block design (CRBD). Factors included three plant densities (200, 300 and 400 plants/m2) and three levels of zinc sulphate (0 - control, 40 and 60 kg/ha). The harvested seeds were then subjected to impact energies of 0.05 and 0.1 J at constant moisture content of 15% using an impact test apparatus. The analysis of variance showed that fertilization level of zinc sulphate (at the 1% probability level), plant density (at the 5% level) and interaction between two variables (at the 5% level) significantly influenced breakage susceptibility of triticale seeds. The average values of percentage breakage of seeds decreased from 32.592 to 16.9268% as the fertilization level of zinc sulphate increased from 0 to 60kg/ha. As the plant density increased from 200 to 400 plants/m2 the percentage breakage of seeds decreased from 27.942 to 21.350%. Increasing the impact energy from 0.05 to 0.1 J caused an increase in the percentage breakage of seeds from 14.07 to 36.9%.

Published: April 2013

Abstract
The long-term experiments carried out at the Agricultural Research Station of Podu-Iloaiei, Iaşi County, Romania, tried to establish some fertilization systems for getting efficient yield increases, which maintain or increase the content of organic carbon from soil. These trials were set up on a 16% slope field, with a cambic Chernozem soil, which has a clayey-loam texture, a neuter to weakly acid response and a mean supply in nutrients. Analyzes performed on soil profiles after 44 years, on land with a slope of 16% and slope length of 310 m, shows that the entire length of slope soil fertility were very different, being influenced by processes of erosion and silting. Soil organic carbon, the depth of 0-20 cm, was between 45.94 t / ha, the foot slope and 27.45 t / ha in the mid-slope area with strong erosion. From the results obtained on erosion in different crop rotations, we have found out that in 16% slope fields from the Moldavian Plateau, soil losses by erosion were diminished below the allowable limit of 3-4 t/ha/year only in case of 4 year-crop rotations with two reserve fields, cultivated with legumes and perennial grasses, which protect soil. Annual soil losses by erosion, registered during the last 30 years, in the Moldavian Plateau, were between 0.246 t/ha in perennial grasses, on the second year of vegetation, and 8.976 t/ha in sunflower. The fertilization of wheat and maize crops at the rate of N80P80 + 60 t/ha manure has determined the increase with 5.5 t/ha (7.8%) in the content of organic carbon from soil, as compared to the rate of N140P100.
Natural Occurence of Deoxynivalenol and Ochratoxin a in Conventional Maize Hybrids and their Biosafety Compared with GM Equivalents
Authors: Muhammad S.A. 
Published: April 2013

Abstract
Familiarity based approval of the newly developed GM cereal events is based upon the stable and safe consumption of conventional grains. The level of concentrations of mycotoxins and biomolecules establishes the criteria for premarket evaluation of genetically modified cereals e.g. MON 810 maize. The objective of the present study was to comparatively evaluate food biosafety of the conventional and GM maize. Grain samples from the harvest lot of 10 maize hybrids in the year 2011 were collected arbitrarily. Well ground and homogenized samples were analysed for the deoxynivalenol (DON) and ochratoxin A (OTA) mycotoxins. Contamination rates and levels of DON and OTA were low and did not exceed the maximum levels, indicating their possible safe use as food and feed under the EC regulation 1881/2006.The samples were further analysed for the possible effect of mycotoxin concentration upon that of starch and proteins. The study reveals the absence of any negative impact of the presence of mycotoxins upon these biomolecules as their concentrations lie within the normal range. A comparative review of data for the mycotoxins in conventional maize grains invalidate the argument from the producers of GM maize hybrids that conventional hybrids are inferior for food biosafety with respect to mycotoxins.
Home, Exile, and Unease in Brian Friel’s Globalized Drama since 1990:Molly Sweeney, The Home Place, andHedda Gabler (after Ibsen)
Authors: Russell Richard Rankin 
Published: April 2013

ABSTRACT:The Irish playwright Brian Friel has often explored the same dynamic and unique event of place as phenomenologist Edward Casey explored in his writings. In Molly Sweeney (1994), Friel shows how this supposedly “disabled” woman gains agency through creating conversations between the living and the dead and thus populating her mind with a rich community. In The Home Place (2005), Friel elegizes the dislocated landlord Christopher Gore and suggests that Margaret and the local singers are briefly liberated from their poverty while singing Thomas Moore’s music. In his Hedda Gabler (after Ibsen) (2008), Friel affirms the imagination through the emplaced collaboration between Thea Elvsted and George Tesman, a collaboration that will help them recreate Eilert Loevborg’s manuscript (even as Hedda kills herself, representing the death-dance of frenetic modernity). In these plays written during Ireland’s rapid globalization, Friel privileges dynamic, often heterogeneous communities that transcend time, space, and gender through the imagination.
Interannual variations of ice cover and wave energy flux in the northeastern Baltic Sea
Authors: Zaitseva-Pärnaste Inga , Soomere Tarmo 
Published: April 2013

AbstractThe major factor shaping the coast of the micro-tidal Baltic Sea is wave activity, the impact of which is limited by the presence or absence of sea ice. Existing studies have revealed almost no correlation between the annual mean wave height and the duration of the ice season. We attempt to evaluate the correlation between ice season duration and bulk wave energy flux (wave power), mean energy and average wave height over the ice-free season for three segments of the Estonian coast (Vilsandi, Pakri and Narva-Joesuu). Statistically significant correlation at the 95% confidence level exists between the duration of the ice season at Vilsandi (a site fully open to the predominant winds) and bulk wave energy flux derived from both observed and modelled wave properties. Similarly strong correlation exists between the mean wave energy and the duration of the ice season at the largely sheltered Narva-Joesuu site.
Qu'est-ce qui est préfabriqué dans la langue ? – Réflexions au sujet d'une définition élargie de la préformation langagière
Authors: Schmale Günter 
Published: April 2013

La préformation langagière, dont la linguistique fait état depuis plus d’un siècle, connaît de nouveaux développements depuis quelque temps, notamment un assouplissement de la notion de figement ainsi qu’un élargissement du champ de recherche à d’autres types d’expressions préformées. Sur la base de sept caractéristiques définitoires de la préformation relatives au degré de l’extension, de la stabilité ou du figement, de l’idiomaticité, de l’ancrage pragmatique, de la saturation lexicale des « constructions », de la dissémination et durabilité de l’usage, ainsi que de la présence d’activités non verbales concomitantes, la présente contribution développe une définition nouvelle élargie des expressions préformées qui seront désormais appelées unités de construction préformées (UCP).
Dispositifs autoritaires et changements politiques. Les cas de l'Égypte et du Maroc
Authors: Ferrié Jean-Noël 
Published: April 2013

La légende dorée de la Révolution française nous a accoutumée à considérer que le Peuple renversait les régimes et que l’explication du changement se trouvait d’abord dans le mouvement social qui se formait. Le « Printemps arabe » n’a pas contribué à tempérer cette manière de voir, bien au contraire. Je vais m’attacher à montrer qu’en amont même de ces crises politiques, il y a eu un affaiblissement de l’autoritarisme lui-même. Il faut chercher, en premier, dans cet affaiblissement l’explication du « Printemps arabe ». L’étude porte principalement sur une comparaison entre le Maroc et l’Egypte.
Sparta e Atene tra Francia e Prussia: da Benjamin Constant a Georg Busolt (1804-1878)
Authors: Pisano Carmine 
Published: April 2013

Dans la période comprise entre l’occupation napoléonienne à Berlin et la guerre franco-prussienne, « la guerre des Péloponnésiens et des Athéniens » devient modèle des conflits politiques et scientifiques qui opposent France et Prusse et qui prennent dans l’historiographie contemporaine les connotations idéologiques du conflit entre Athènes et Sparte. Le phénomène a été étudié par Pierre Vidal-Naquet et Nicole Loraux dans le contexte de l’historiographie française, où l’opposition à la Prusse est définie à travers le conflit entre « une Athènes bourgeoise et lettrée » et « une Sparte vertueuse et militaire ». La présente contribution se propose d’évaluer dans quelle mesure changent, de la France à l’Allemagne, l’analyse de la Guerre du Péloponnèse et la représentation des modèles républicains anciens, c’est-à-dire d’analyser comment les intellectuels français et allemands relisent et redéfinissent les catégories de « Spartiate » et « Athénien » dans les limites du débat politique-culturel du xixe siècle.
L’invention de la numismatique : des arts décoratifs aux sciences auxiliaires de l’histoire
Authors: Guillemain Jean 
Published: April 2013

Le médaillon avec tête de profil apparaît en Italie au milieu du xve siècle, d’abord dans les représentations d’architectures imaginaires puis dans la sculpture monumentale. Ce motif s’exporte en Europe au début du siècle suivant et connaît sa plus grande expansion au moment où fleurissent les recueils de portraits d’hommes illustres tirés des monnaies et médailles (vers 1520-1560). Après les artistes et les décorateurs, les antiquaires s’intéressent aux revers monétaires, dont ils découvrent le sens grâce aux sources littéraires. Dans le domaine de l’histoire du livre, l’évolution de la page de titre reflète les changements de la mode, depuis les titres à encadrement avec médaillons sur les pilastres et les écoinçons, jusqu’aux marques d’imprimeurs qui se fondent sur l’iconographie des revers, considérée alors comme de nature emblématique.
