Authors: Alibas Ilknur , Koksal Nezihe 
Published: May 2015

Abstract
The aim of the present study was to determine various physical, mechanical, and structural characteristics of seed of pepper cultivars Yağlık Kapya, Demre Sivri, Yalova Carliston, Kandil Dolma, and Cin Sus Yediveren, which are grown extensively in Turkey, with initial moisture content ranging between 7.03 and 7.21% (w.b.). Width, length, and thickness were found to be in the range of 3.00-3.72, 3.43-4.40, and 0.66-0.82 mm, respectively. It was revealed that sphericity of the seeds of Yağlık Kapya, Demre Sivri, Yalova Carliston, Kandil Dolma, and Cin Sus Yediveren were 51, 57, 56, 51 and 57%, respectively. In terms of the roundness which ranges between 76 and 85% depending on pepper cultivars. The aspect ratio of Yağlık Kapya, Demre Sivri, Yalova Carliston, Kandil Dolma, and Cin Sus Yediveren were determined to be 84.60, 88.04, 94.43, 85.55, and 87.67%, respectively. It was also noted that the porosity of the pepper seeds was in the range of 44.94-49.61%. Besides, we found that as the weight of pepper seeds increased, their terminal velocity increased accordingly, and thus terminal velocities were found to be 2.87-4.66 m s-1. In the current study, the static friction angle and coefficients of the cultivars were determined by means of six different plates including aluminium, stainless steel, galvanized iron, rubber, glass, and plywood. The plywood plate was found to be the least slippery; consequently, the static friction angle and coefficient were determined to be the highest for the plywood plate.

Abstract
The paper aims at presentation of results of research on integration of image and laser data based on selected example. Since a few years the authors have been conducting research on processing image data, and those obtained from laser scanning in the form of the so-called point cloud. In experiments data from terrestrial and mobile laser scanning gained for two different objects were compared: a parish house from Goźlice located in the open-air ethnographic museum at the village of Tokarnia, Poland, and part of the Cracow-Warsaw railway line. The results of those experiments proved that data in the form of point cloud were not always sufficient for a precise 3D model reconstruction. Supplementing point clouds with photogrammetric images seems to be the best solution.

Authors: Pawlik Piotr , Bubliński Zbigniew , Głowacz Andrzej 
Published: May 2015

Abstract
The aim of this work was to develop an algorithm for estimating the waiting time of the cars stopped before the intersection in a traffic flow measurement system (based on optical flow), which does not require the generation of the background and allows to calculation in real time. The proposed method performs analysis in HSV color space - a mask generated from S component is applied to H component. In this way a background - an asphalt and horizontal whitespace - is eliminated. The result of this operation is combined with data from optical flow to detect the vehicles which should be tracked.
A Competitive Study of Graph Reduction Methods for Min S-T Cut Image Segmentation
Authors: Węgliński Tomasz , Fabijańska Anna , Goclawski Jarosław 
Published: May 2015

Abstract
When applied to the segmentation of 3D medical images, graph-cut segmentation algorithms require an extreme amount of memory and time resources in order to represent the image graph and to perform the necessary processing on the graph. These requirements actually exclude the graph-cut based approaches from their practical application. Hence, there is a need to develop the dedicated graph size reduction methods. In this paper, several techniques for the graph size reduction are proposed. These apply the idea of superpixels. In particular, two methods for superpixel creation are introduced. The results of applying the proposed methods to the segmentation of CT datasets using min-cut/max-flow algorithm are presented, compared and discussed.
Color-Aware Packet Marking Based on H.264AVC Coder Extensions for Improved Video Quality
Authors: Przylucki Slawomir 
Published: May 2015

Abstract
In recent years there is a noticeable trend to implement the video transmission systems based on shared IP networks. At the same time new generations of video codecs such as H.264 are used in industrial installations. This situation forces the need for consideration of methods for efficient video transmission in industrial networks such as surveillance, identification and control systems. The first part of the article discusses the features of modern video codecs, relevant to the streaming applications. Attention is focused on the extensions of the H.264 standard that increase the error-resilience, particularly Data Partitioning (DP) and Flexible Macroblock Ordering (FMO). Next, the principles of prioritization of the video traffic based on the DiffServ architecture is discussed. In this context, separated section presents in detail the rules for packets marking which enable appropriate forwarding the video data. This information is referenced to current recommendations and technical standards. Next the performance of several classical packet marking algorithms and their possible modifications using FMO- and DP-based errorresilience configurations of H.264 are verified in simulations.
The Romanian Migrants in Spain. An Exceptional Migratory Flow
Authors: Martínez Rafael Viruela 
Published: May 2015

Abstract
The Romanian population is the most important foreign population in Spain. Romanian migrants are characterized by their large number (about 800.000 residents and 268.000 contract workers) and their rapid growth. The economic and labour motivation for migration determines their geographical distribution, with high numbers of Romanian migrants in cities and in areas of agricultural, industrial and tourist industries. However, a high proportion of Romanian migrants also live in small towns and rural areas. Most of them were already illegal migrants when Romania entered the EU and they became EU citizens. From January 1st 2009, these once illegal migrants now have full freedom of employment in Spain. They adapt to circumstances of each period of time, in order to enter or to remain in the Spanish labour market. Most work in construction and agriculture as well as domestic services, trade, tourism and industries. The current economic crisis and the resulting unemployment have raised the issue of return migration to Romania.
Architectural Firms in Transylvania. Objective Positions and Field Positioning
Authors: Pop Cristian 
Published: May 2015

Abstract
I will discuss in this article the dynamics of business groups, using the case of architects from three Transylvanian cities (Cluj-Napoca, Timisoara and Brasov with emphasis on Cluj-Napoca). The architecture companies successfully represent the current trends of company organization in dynamic contexts, generated by the market changes, where services become the most important products of large cities. Using a sample of 375 architectural companies from these cities that employ 616 persons, I outline a field model inspired by Bourdieu’s work. My argument is that the large number of actors in the architectural networks from Cluj-Napoca is explained by the different forms of educational, economic, social and politic capital mobilized to create competitive companies and to survive within an instable post-socialist economic environment. Moreover, the internal structure of network organization from Cluj-Napoca is based on the usage of different types of available capital.
‘Serious girls’, prostitutes and ‘whores’. Calling genders to order
Authors: Maia Marta 
Published: May 2015

Abstract
The sexual representations and the sexual experiences of individuals are marked by the gender they belong to, which induces social roles and differentiated ideals and determines behaviours, namely those that concern the body and sexuality. The speeches of young people questioned in an ethnological investigation on sexual representations in the Eastern suburb of Paris, denounce the opposition between feminine and masculine values, and show the difference between the representations and behaviours of young males and females. The speeches of young people denote a distinction between the ‘serious girl’, the prostitute and the ‘whore’, which marks a hierarchy of moral values, in relation to their behaviour in general and to their sexual behaviour in particular.
The Metamorphosis of Tea. Teahouses and Tea shops in Bucharest
Authors: Luca Gabriela 
Published: May 2015

Abstract
This paper examines the increase of public, non-domestic tea consumption in Bucharest. In order to offer a full picture, I approached the consumer engines in terms of both teahouses’ owners and consumers. I found that most entrepreneurs have established their business in an effort to have a place of their own, quiet, where to practice their passions with people who share the same values and interests. Consumers, in turn, are attracted primarily by the interior space of the teahouses. Their reasons are the most diverse: for relaxation and dreaming, to escape from the city’s violent stimuli, for introspection, for new bodily experiences, to strengthen or build friendship, romantic or business relationships, as well as for the ‘dream’ characteristics of the teahouses’ environment. Both the teahouses’ owners and their consumers may be regarded as varieties of prosumers.
Should You Accept a Friends Request From Your Mother? And Other Filipino Dilemmas
Authors: Miller Daniel , Madianou Mirca 
Published: May 2015

Abstract:
This paper uses the concept of ‘cutting the network’ derived from the work of Marilyn Strathern to examine the relationship between two kinds of social network, that of kinship and the system of friends constructed on social networking sites. Specifically the material comes from a study of Filipina domestic workers and nurses in the UK and their relationship to their left behind children in the Philippines. A bilateral system of kinship can lead to a proliferation of relatives, while the use of the Friendster social networking site can lead to a proliferation of friends. It is when these two systems clash following the request by one's mother to become a friend that the constraints and problems posed by both systems comes into view. Cases show that it is possible to use social networking sites to help mothers become close friends for their absent children, but more commonly the increasing presence of actual mothers through new media disrupts the relationships that children had developed for themselves to a idealised projection of motherhood.
Globalizing Locations: Production-Consumption Relations in the Hip-hop Movement in Brazil and Portugal
Authors: de Souza Angela Maria 
Published: May 2015

Abstract:
This article is part of the ethnography for the doctoral thesis in social anthropology, in which the fieldwork was conducted in Greater Lisbon and Greater Florianópolis on the hip hop Movement. This analysis addresses two rap styles, Rap Creole, in Lisbon, made predominantly by Cape Verdeans and Angolans immigrants, and in Florianópolis, rap de quebrada, a form of expression of the population, mostly black residents, of the periphery. In both rap styles can be perceived the development of an aesthetics that becomes outlined in the tension between the individual and the collective, the global and the local. Based on the styles mentioned here, I reflect on consumption relations that create networks and flows among the hip hop movement in different urban spaces, creating a kind of parallel globalization among the peripheries, but remaking itself in a variety of cultural contexts.
A Place Called Supermarket
Authors: Goidanich Maria Elisabeth , Rial Carmen 
Published: May 2015

Abstract:
The objective of this study is to interpret supermarket stores as privileged spaces for the observation of social relations. The article is based on an ethnography of shopping conducted in the city of Florianópolis, Brazil, by observing middle class housewives during their daily shopping in supermarkets. These stores are seen as places, in opposition to that proposed by Augè (1995), who affirms that supermarkets are non-places produced by supermodernity. The article discusses the history of supermarkets, their role in the cultural and social transformations of the twentieth century, as well as ethnographic data, and shows that it is possible to identify many social interactions inside Brazilian supermarkets.
Interpolation Of Data Gaps Of SLC-Off Landsat ETM+ Images Using Algorithm Based On The Differential Operators
Authors: Singh Raghvendra , Prasad P. Rama Chandra 
Published: May 2015

Abstract
The scan-line corrector (SLC) of the Landsat 7 Enhanced Thematic Mapper Plus (ETM+) sensor failed in May 2003, and this abnormal functioning of SLC resulted in about 22% of the pixels per scene without being scanned. By filling the un-scanned gap by a good technique will help in more use of ETM+ data for many scientific applications. While there have been a number of approaches developed to fill in the data gaps in ETM+ imagery, each method has shortcomings, especially they require SLC-on (images acquired before SLC-off anomaly) imagery for the same location to fill the gaps in SLC-off (images acquired after SLC anomaly) image. To overcome such shortcomings this study proposes an alternative interpolation method based on the partial derivative. This case study shows that this technique is very much useful to interpolate the missing pixel values in the SLC-off ETM+ data.
AnnoGene: RESTful Web Service For Annotating Genomic Features
Authors: Tomski Andrzej , Piechota Marcin , Przewłocki Ryszard 
Published: May 2015

Abstract
Modern high-throughput sequencing techniques generate a constantly increasing amount of genomic data from eukaryotes. The main problem is quickly identifying the data that may provide information about the nature of intracellular processes, such as the targeting of transcription factor-binding sites. Typically, thousands of peaks or signals are found across the genome and the nearby genes must be annotated. We introduce AnnoGene - a web service for annotating genomic features. AnnoGene was implemented in a representational state transfer (REST) architectural style. The program searches for the gene nearest to the center of a genomic position. Subsequently, the location and annotationsof the gene are shown. The tool can be downloaded and run on a local computer, but it was designed to be a web service. AnnoGene is freely available through a web browser. Moreover, our paper covers examples of the REST clients written in the Python, R and Java programming languages. AnnoGene only requires genomic positions from the user. Even when annotating several thousand positions, the output is typically ready in a few seconds. Moreover, this tool supports Seqinspector – a web tool for finding regulators of the genes.
Automated Approach To Classification Of Mine-Like Objects Using Multiple-Aspect Sonar Images
Authors: Wang Xiaoguang , Liu Xuan , Japkowicz Nathalie , Matwin Stan 
Published: May 2015

Abstract
In this paper, the detection of mines or other objects on the seabed from multiple side-scan sonar views is considered. Two frameworks are provided for this kind of classification. The first framework is based upon the Dempster–Shafer (DS) concept of fusion from a single-view kernel-based classifier and the second framework is based upon the concepts of multi-instance classifiers. Moreover, we consider the class imbalance problem which is always presents in sonar image recognition. Our experimental results show that both of the presented frameworks can be used in mine-like object classification and the presented methods for multi-instance class imbalanced problem are also effective in such classification.
Flatness-Based Adaptive Fuzzy Control Of Spark-Ignited Engines
Authors: Rigatos Gerasimos G. , Siano P. 
Published: May 2015

Abstract
An adaptive fuzzy controller is designed for spark-ignited (SI) engines, under the constraint that the system's model is unknown. The control algorithm aims at satisfying the H
∞ tracking performance criterion, which means that the influence of the modeling errors and the external disturbances on the tracking error is attenuated to an arbitrary desirable level. After transforming the SI-engine model into the canonical form, the resulting control inputs are shown to contain nonlinear elements which depend on the system's parameters. The nonlinear terms which appear in the control inputs are approximated with the use of neuro-fuzzy networks. It is shown that a suitable learning law can be defined for the aforementioned neuro-fuzzy approximators so as to preserve the closed-loop system stability. With the use of Lyapunov stability analysis it is proven that the proposed adaptive fuzzy control scheme results in H
∞ tracking performance. The efficiency of the proposed adaptive fuzzy control scheme is checked through simulation experiments.
Analysis of Fiscal Rules in the European Monetary Union
Authors: Šehović Damir 
Published: May 2015

Abstract
: The EMU fiscal system is specific in many areas compared to other classic fiscal systems of national states. Specific features mainly reflect in the implementation of economic policy within the EMU which is carried out by combining a common centralized monetary policy under the ECB jurisdiction and decentralized fiscal policies under the jurisdiction of the member states. The member states` sovereignty in governing their fiscal policies is one of the key causes of the EU fiscal system underdevelopment, i.e. its indigent structure in relation to “standard fiscal systems”.
More indigent structure of the EU fiscal system is reflected in the fact that it consists of only three segments. The first one refers to the EU budget which is also the only instrument for implementing fiscal policy at the supranational level. The second one refers to the harmonization of taxation systems in accordance with inputs and other legislation adopted at the EU level with the aim of fostering the single internal market. Finally, the third segment refers to the fiscal policy coordination of the EMU member states related to appropriate fiscal rules, which mainly stem from the Maastricht convergence criteria and the Stability and Growth Pact.
Macroeconomic and Institutional Determinants of Non-performing Loans
Authors: Tanasković Svetozar , Jandrić Maja 
Published: May 2015

Abstract
This paper aims to analyse macroeconomic and institutional empirical determinants of growth of NPL ratios. Research is focused on selected CEEC and SEE countries in the period 2006- 2013. For our analysis we use static panel model approach with the logarithm of share of NPLs to total loans as a dependent variable. As independent variables we used a combination of country-specific macroeconomic and financial indicators which are commonly used in reference literature, as well as relevant institutional variables. Our results show that there is a negative relationship between increases in GDP and rise of the NPL ratio. Along with GDP, foreign currency loans ratio and level of exchange rate are positively related with the increase of NPL ratio. This confirms the expectation that countries where domestic currency is not the main medium of credit placements will have larger problems with the level of NPLs, which is even more pronounced in periods of domestic currency depreciation. In the presented models, the inflation rate is reported as statistically insignificant for sample countries. In the group of institutional variables, only financial market level of development is reported as statistically significant in relation to the level of NPL - with a more developed financial market the level of NPLs should be lower.
Analysis And Synthesis Of Model Reference Controller For Variable Speed Wind Generators Inertial Support
Authors: Bećirović Elvisa , Osmić Jakub , Kušljugić Mirza , Perić Nedjeljko 
Published: May 2015

Abstract
Model Reference Controller (MRC) for contribution of Variable Speed Wind Generators (VSWG) in inertial response of Electrical Power System (EPS) is presented and analyzed in this paper. MRC is synthesized based on a model of Generating Unit With non-Reheat Steam Turbine (GUNRST) thus enabling VSWG to emulate GUNRST response during the initial stage of dynamic frequency response ie inertial phase. Very important property of conventional steam generating units is that its contribution to inertial phase response is independent from the initial generating power. By using MRC in VSWG it is accomplished that in most common wind speed region (3-12 m/s) VSWG inertial support is almost independent from wind speed. Since in most EPSs VSWG replaces conventional steam generators, application of MRC algorithm provides that the characteristics of EPS in terms of inertial response are preserved, regardless of the growing trend of introducing VSWG. Evaluation analysis of the proposed MRC is performed on modified nine bus power system when VSWG with MRC is connected to one of the power system buses.
Uncertainty Of The Measurement Of DC Conductivity Of Eramics At Elevated Temperatures
Authors: Štubňa Igor , Trnovcová Viera , Vozár Libor , Csáki Štefan 
Published: May 2015

Abstract
The electrical DC conductivity is measured at room and elevated temperatures on green ceramic samples prepared from kaolin. The arrangement of the sample, with two platinum wire electrodes inserted in the kaolin prism that was used is suitable for measurements of temperature dependences of the DC conductivity from 20 °C to 1100 °C in the air. The uncertainty analysis taking into account thermal expansion of the sample, homogeneity of the temperature field, measurement regime, corrosion of the electrodes, and overlapping of the electrodes is done for 1000 °C. Uncertainties connected with current and voltage measurements and uncertainties connected with the instruments that were used are also considered. The sum of all the partial uncertainties gives an expanded uncertainty of the conductivity measurement. The uncertainty varies with temperature and reaches the value of ∼ 6.5% at 1000 °C.
Study Of The Fluxset Magnetic Probe Speed–Sensitivity Developed For Detection Of Magnetic Nanoparticles In Surgery
Authors: Datz Dániel , Gasparics Antal , Vértesy Gábor 
Published: May 2015

Abstract
Markers for imaging are vital parts of surgical processes. Since radioactive compound pose considerable risk to both the recipient and the surgical staff, alternative marking techniques are of interest. In NANOMAGDYE project, magneto-optically active nano-particles were created for this reason. The detection of the magnetic interaction of low mass nano-particles in surgical environment is very challenging; so far only quasi-stationary measurements were taken. This paper shows a measurement setup for measurements with continuously moving probe at lower velocities (5–10 mm/s) and at hand movement velocity (20–30 cm/s). It was found that at the velocity of hand movement there is only probe response amplitude reduction of at most 10–15% of the original amplitude. These results indicate that the probe used for the detection of the nano-particles is sufficient to be used in practical purposes in surgery.
