Text Segmentation from Bangla Land Map Images
Authors: Biswas Samit , Kumar Das Amit , Chanda Bhabatosh 
Published: May 2015

Abstract
Text segmentation from land map images is a non-trivial task as map components are interleaved and overlapped in a complex spatial form. The characters in a word in most of the Indic languages, including Bangla (the 6th most spoken language in the world), are connected through a headline (”matra” or ”shirorekha”) which makes the corresponding word a single component. It has been observed that the Delaunay triangulation (DT) forms a number of small triangles on the text regions compared to other regions of the map - a property very much discernible for Bangla (and some other Indic scripts) texts. This property is primarily exploited here to segment text from the complex background of the land map images. The proposed text segmentation approach is tested and compared with an existing method on a collected dataset of paper map images( containing Bangla, an Indian regional language texts) and the results are encouraging.
RSA Problem for Varying Traffic in Flexible Optical Networks
Authors: Olszewski Ireneusz 
Published: May 2015

Abstract
The problem of service time-varying traffic in flexible transparent optical networks, assuming that the incoming connections and their duration are not known in advance, is considered in this work. Time-varying traffic requires dynamic spectrum allocation for connections implemented in the network. In the considered problem, a path with the required spectrum around the reference frequency is determined for each incoming connection by the routing algorithm. In order to take into account the dynamic spectrum allocation for the connections in the network, two spectrum expansion/- contraction schemes have been applied on the basis of which the average blocking probability for the incoming request additional slot was determined.
3D Segmentation of Funnel Flow Boundary During Silo Emptying
Authors: Waktola Selam , Babout Laurent , Grudzien Krzysztof 
Published: May 2015

Abstract
The paper presents an automatic method for segmenting 3D tomography images of a funnel flow area, during silo emptying process. For generating 3D images the silo model was scanned using X-ray Computed Tomography (CT) system. The method has been applied for a chosen single slice from 3D image. The image segmentation is based on the variance of pixels calculation in defined interrogation window (or kernel). The analysis of Signalto- Noise-Ratio (SNR) of the given image allows to improve the contrast in the image and facilitate the detection the boundary between funnel area and stagnant zone. The obtained results of image segmentation show a high potential in the silo flow investigation using in-situ experiment using X-ray visualization. Additionally, the study indicates that, the separation of the silo area into the funnel and stagnant zone parts is a very challenging task especially for the top and bottom area of silo where the contrast is the smallest.

Abstract
This paper presents a method of automatic recognition of thiarubrine canals in images obtained with Optical Coherence Tomography technique. The plant material was the Ri-transformed root culture of South American herb Schkuhria pinnata. The series of highresolution OCT B-scans for the study were collected using custom made experimental system operating light of 800 nm central wavelength. The method reduces significant artefacts and uses region growing approach adapted to specific features of OCT images. Results of the identification have been compared with data obtained by specialist for selected B-scans. The algorithm accuracy was also verified using a simple numeric phantom.
Migrants and healthcare within the European Union
Authors: Nagy Raluca 
Published: May 2015

Abstract
The investigation of migration can help us understand how the types of migration interact with each other as well as with the various local/national ‘immobilities’. Migrants pose special challenges to healthcare systems, in their origin as well as destination countries. Available data on this topic, following EU interests and policies, focuses on health problems of vulnerable migrant groups, often directed exclusively to issues that can affect the local population. This paper aims to set some explanatory contexts when it comes to the relationship between migration and healthcare within the European context.
The structure of mnemonic revolutions
Authors: Rusu Mihai-Stelian 
Published: May 2015

Abstract
This article proposes an evolutionary model of collective memory built on the concept of mnemonic revolution. It tries to go beyond the apparently mutual exclusive theories existing in sociological literature by integrating them into a comprehensive conceptualization. The first part of the study begins with the presentation of competing theories of collective memory developed over time. The second step presents the theoretical formula resulting from the adoption of a broader time frame (longue durée). This formula also takes into consideration the introduction of the concepts of mnemonic revolution and mnemonic reform. Mnemonic revolution is defined as a major break occurred in the structure of collective memory, which succeeds in a sociopolitical revolution, whereby the entire representation of the past is abandoned and the social labor of constructing a new retrospective vision of the past is initiated. Mnemonic reform includes the adjustable changes and the superficial reconfiguration through which the general image of the past that is incorporated into the collective memory is slightly calibrated depending on the evolution of the social system. The final part presents in a synthetic manner the way in which I sought the empirical validation of the notions developed in order to capture the dynamics of collective memory.
Mosaics of Inclusion: Reflections on Thames Chase Community Forest
Authors: Pinder Ruth 
Published: May 2015

Abstract
This paper reflects on a practitioner-grounded metaphor – the mosaic – as a means to think the relationship between health and the environment in two policy initiatives, a walking and a conservation group. These were both part of Thames Chase Community Forest, a UK-based nature program to combat ill-health, poverty and social exclusion for those on the fringe of large urban conurbations. Using multiple research methods, the paper questions the simple, literal, equal-but-separate notions of the two pre-set policy parameters to show how the solidarity that mattered could not be fixed in advance. It was a mosaic-in-the-making, that came to life along the way, within the shifting ground of patterned regularities, people and happenings that often escape the net of rapid approaches to ethnographic policy research. Such reflections might usefully offer fresh soundings for policy-makers to contemplate, not merely a blueprint to be followed.
Domesticating Feelings Through Short Message Service (SMS)
Authors: Moise Raluca 
Published: May 2015

Abstract
Starting from the ostentatious presence of the SMS for teenagers, I attempted to identify the values of its appropriation process and to outline the trajectory of SMS within teenage culture. My argument is that the SMS develops two interpenetrating usage trajectories: an individual and a collective line, the later bearing a marked cultural logic. The relation between the object of consumption and the individual is framed by specific values of usage and regulated by cultural practices. In this article, I will present the factors that regulate the individual usage of the SMS, incorporating this form of communication in teens’ universe. Through ethnographic fieldwork in Romania, I have carried out participant observation and interviews in places that are frequented by teenagers and I have collected and analyzed more than 300 text messages, written by teenagers in daily personal journals of communication.
Music and Youth in Brazilian Contemporary Society
Authors: Barbosa Lívia , Veloso Letícia , Dubeux Veranise 
Published: May 2015

Abstract:
Based on qualitative and quantitative research with 1,080 youth in the Brazilian cities of Rio de Janeiro, São Paulo, and Porto Alegre, this article analyzes the role of music in the constitution of young people's everyday lives. Focusing on how youth obtain, store, and listen to music, as well as on how they describe the presence of music in their lives, we argue that music – facilitated by digital technology – permeates and gives meaning to young people's lives in a way more pervasive than ever before, to the extent that, in their words, it constitutes the ‘soundtrack’ of each individual life. We propose to understand this puzzling statement through a material culture framework, and to do so we ask: how do youth currently give meaning to music as a key feature of life, and how do music and the objects through which it is experienced constitute life as such?
The Configuration of ‘Young’ Spaces in Brasil in the late 1960s: Pop Domesticity Through the Perspective of the Magazine Casa & Jardim
Authors: dos Santos Marinês Ribeiro , Pedro Joana Maria , Rial Carmen 
Published: May 2015

Abstract:
The pop movement appeared in industrial Western societies as a manifestation of the urban youth culture. It is frequently associated with the worldwide behavioral revolution of the sixties. Part of the youth population used pop expressions with irreverent and strong visual impact as generation markers. This article affirms that pop artifacts of the 1960s and 1970s found in Brazilian interior decoration are part of the material culture of that period as included in domestic spaces designed for youth. We argue that pop artifacts and interior decoration in the country both expressed and shaped new behavioral patterns among young people. Our sources are particular representations of domestic spaces published in issues of the popular magazine Casa & Jardim.

New Ranking Method For Fuzzy Numbers By Their Expansion Center
Authors: Wang Zhenyuan , Zhang-Westmant Li 
Published: May 2015

Abstract
Based on the area between the curve of the membership function of a fuzzy number and the horizontal real axis, a characteristic as a new numerical index, called the expansion center, for fuzzy numbers is proposed. An intuitive and reasonable ranking method for fuzzy numbers based on this characteristic is also established. The new ranking method is applicable for decision making and data analysis in fuzz environments. An important criterion of the goodness for ranking fuzzy numbers, the geometric intuitivity, is also introduced. It guarantees coinciding with the natural ordering of the real numbers.
Repulsive Self-Adaptive Acceleration Particle Swarm Optimization Approach
Authors: Ludwig Simone A. 
Published: May 2015

Abstract
Adaptive Particle Swarm Optimization (PSO) variants have become popular in recent years. The main idea of these adaptive PSO variants is that they adaptively change their search behavior during the optimization process based on information gathered during the run. Adaptive PSO variants have shown to be able to solve a wide range of difficult optimization problems efficiently and effectively. In this paper we propose a Repulsive Self-adaptive Acceleration PSO (RSAPSO) variant that adaptively optimizes the velocity weights of every particle at every iteration. The velocity weights include the acceleration constants as well as the inertia weight that are responsible for the balance between exploration and exploitation. Our proposed RSAPSO variant optimizes the velocity weights that are then used to search for the optimal solution of the problem (e.g., benchmark function). We compare RSAPSO to four known adaptive PSO variants (decreasing weight PSO, time-varying acceleration coefficients PSO, guaranteed convergence PSO, and attractive and repulsive PSO) on twenty benchmark problems. The results show that RSAPSO achives better results compared to the known PSO variants on difficult optimization problems that require large numbers of function evaluations.
Temporal Analysis Of Adaptive Face Recognition
Authors: Akhtar Zahid , Rattani Ajita , Foresti Gian Luca 
Published: May 2015

Abstract
Aging has profound effects on facial biometrics as it causes change in shape and texture. However, aging remains an under-studied problem in comparison to facial variations due to pose, illumination and expression changes. A commonly adopted solution in the state-of-the-art is the virtual template synthesis for aging and de-aging transformations involving complex 3D modelling techniques. These methods are also prone to estimation errors in the synthesis. Another viable solution is to continuously adapt the template to the temporal variation (ageing) of the query data. Though efficacy of template update procedures has been proven for expression, lightning and pose variations, the use of template update for facial aging has not received much attention so far. Therefore, this paper first analyzes the performance of existing baseline facial representations, based on local features, under ageing effect then investigates the use of template update procedures for temporal variance due to the facial age progression process. Experimental results on FGNET and MORPH aging database using commercial VeriLook face recognition engine demonstrate that continuous template updating is an effective and simple way to adapt to variations due to the aging process.

Construction of Residental Buildings on Columns as an Alternative to Construction in Areas Exposed to Floods
Authors: Kušar Domen , Volgemut Mateja 
Published: May 2015

Abstract
Floods that have in recent years become a constant in developed areas are raising the issue of how to adapt to nature when constructing housing. The construction of retarding basins and high dikes are the most frequently used alternatives of protecting the urban environment. Such a practice is most commonly found in Europe where it however, has unfortunately shown itself on several times, not to be the most effective. People from North America who live in areas often affected by floods, build their housing on columns. In Slovenia, not much thought is given to this, which is probably the result of the traditional mentality that promotes the building of massive residential houses and the issue of structural engineering that involves the so-called soft ground floor. New materials and new structural principles make construction on columns possible, which has been proven by the example of the residential building on low bearing soil in the seismic and flood risk area of the Ljubljana Marshes.

Experience from geodetic very long baseline
interferometry observations at Onsala using a
digital backend
Authors: Kareinen N. , Haas R. 
Published: May 2015

Abstract
The Onsala Space Observatory has installed a
modern digital backend for geodetic and astronomical
Very Long Baseline Interferometry (VLBI). This system
consists of a Digital Base-Band Converter (DBBC) and a
Mark 5B+ recorder. From 2011 until late 2014 this new
system was run for geodetic VLBI observations in parallel
with the old system consisting of a Mark 4 rack and
Mark 5A recording system. Several of these observed sessions
were correlated at the correlator in Bonn including
both data sets. We present results from the analysis and
comparison of these sessions. Both the original observed
delays and corresponding geodetic parameters are compared.
No significant differences are detected, for either
the raw observations or for the geodetic parameters. This
shows that the digital backend can be used operationally
for geodetic VLBI observations.
Estimating the rainfall erosivity factor from monthly precipitation data in the Madrid Region (Spain)
Authors: Hernando David , Romana Manuel G. 
Published: May 2015

Abstract
The need for continuous recording rain gauges makes it difficult to determine the rainfall erosivity factor (Rfactor) of the Universal Soil Loss Equation in regions without good spatial and temporal data coverage. In particular, the R-factor is only known at 16 rain gauge stations in the Madrid Region (Spain). The objectives of this study were to identify a readily available estimate of the R-factor for the Madrid Region and to evaluate the effect of rainfall record length on estimate precision and accuracy. Five estimators based on monthly precipitation were considered: total annual rainfall (P), Fournier index (F), modified Fournier index (MFI), precipitation concentration index (PCI) and a regression equation provided by the Spanish Nature Conservation Institute (RICONA). Regression results from 8 calibration stations showed that MFI was the best estimator in terms of coefficient of determination and root mean squared error, closely followed by P. Analysis of the effect of record length indicated that little improvement was obtained for MFI and P over 5- year intervals. Finally, validation in 8 additional stations supported that the equation R = 1.05·MFI computed for a record length of 5 years provided a simple, precise and accurate estimate of the R-factor in the Madrid Region.
Statistical Disclosure Limitation in the Presence of Edit Rules
Authors: Kim Hang J. , Karr Alan F. , Reiter Jerome P. 
Published: May 2015

Abstract
We compare two general strategies for performing statistical disclosure limitation (SDL) for continuous microdata subject to edit rules. In the first, existing SDL methods are applied, and any constraint-violating values they produce are replaced using a constraint-preserving imputation procedure. In the second, the SDL methods are modified to prevent them from generating violations. We present a simulation study, based on data from the Colombian Annual Manufacturing Survey, that evaluates the performance of the two strategies as applied to several SDL methods. The results suggest that differences in risk-utility profiles across SDL methods dwarf differences between the two general strategies. Among the SDL strategies, variants of microaggregation and partially synthetic data offer the most attractive risk-utility profiles.

Electric Vehicles Mileage Extender Kinetic Energy Storage
Authors: Jivkov Venelin , Draganov Vutko , Stoyanova Yana 
Published: May 2015

Abstract
The proposed paper considers small urban vehicles with electric hybrid propulsion systems. Energy demands are examined on the basis of European drive cycle (NEUDC) and on an energy recuperation coefficient and are formulated for description of cycle energy transfers. Numerical simulation results show real possibilities for increasing in achievable vehicle mileage at the same energy levels of a main energy source - the electric battery. Kinetic energy storage (KES), as proposed to be used as an energy buffer and different structural schemes of the hybrid propulsion system are commented. Minimum energy levels for primary (the electric battery) and secondary (KES) sources are evaluated. A strategy for reduced power flows control is examined, and its impact on achievable vehicle mileage is investigated. Results show an additional increase in simulated mileage at the same initial energy levels.
