Vulnerabilities and Threats to Human Security Generated by an Ineffective Educational System
Authors: Macrea Rareș , Macrea Petronela 
Published: July 2017

Abstract
The present trend towards globalization has led to people changing their views on possible threats to their existence. Nowadays, we witness a diversification of vulnerabilities and threats to human security, as well as a progressive reduction of our resilience. The article attempts to correlate the 5 dimensions of national security, as identified by the Copenhagen School of Security, with the problems of the Romanian educational system, explaining how these problems can become threats to the security of Romanian citizens. It offers an overview of the problems of the Romanian educational system, and the threats and vulnerabilities derived from them towards human security. It also suggests solutions to problems and indicators for monitoring progress.

Published: July 2017

Abstract
The scattering of electromagnetic (EM) waves, emitted by a monostatic radar, from two - dimensional (2D) rough fractal surfaces is examined by using the Kirchhoff approximation. We examine the way that the level of roughness of the fractal surface affects the backscattered EM wave captured by a radar as a function of frequency (therefore, a ‘spectral method’) and whether the roughness of the surface can be estimated from these radar measurements. The backscattering coefficient is calculated for a number of radar frequencies and for different values of the surface fractal dimension. It is found that the values of the slopes between the main lobe and the first sidelobes of the backscattering coefficient as a function of the wave number (frequency) of the incident EM waves increase with the surface fractal dimension. Therefore, we conclude that the magnitude of the above slopes provides a reliable method for the classification of the rough fractal surfaces. Furthermore, concerning three - dimensional (3D) fractal surfaces, investigations similar to the above are already performed by the authors and will be presented during the Conference. The above are also investigated in the presence of electronic noise in the radar receiver (effect of SNR values in the above proposed technique).

Published: July 2017

Abstract
The alysis of free vibrations on rectangular plates with mixed conditions of buckling in the thermal environment is carried out by means of the 3D elasticity theory. In this paper there has been analyzed by the finite element method (FEM), the mode shape and the eigen-frequencies for a rectangular plate clamped on the contour for different temperatures. In this analysis successive heat degrees have been used, this fact helping to find the critical values in which the frequencies were at zero and to correlate these temperatures with the values obtained from the static analysis The temperature rise, the material graded index and the geometrical parameters on the eigen-frequencies were studied.

Abstract
This work was focused on changes of corrosion behaviour influence of deformation. The This work focuses on changes in corrosion behaviour under the influence of deformation. The main purpose is to observe the changes caused by tensile stress. The experimental material used is steel 1.4301 and titanium GRADE 2. The measurements were carried out using a potentiostat, which measures potential changes over time and electric current. The electrolyte used was 3.5% NaCl. Corrosion properties, especially polarization resistance, corrosion potential and corrosion rate, were evaluated from the measurements. The results demonstrate the changing corrosion properties depending on deformation. The corrosion properties worsened as the deformation increased.

Random walk on spheres algorithm for solving transient drift-diffusion-reaction problems
Authors: Sabelfeld Karl K. 
Published: July 2017

Abstract
We suggest in this paper a Random Walk on Spheres (RWS) method for solving transient drift-diffusion-reaction problems
which is an extension of our algorithm we developed recently [26]
for solving steady-state drift-diffusion problems.
Both two-dimensional and three-dimensional problems are solved. Survival probability, first passage time and the exit position for a sphere (disc)
of the drift-diffusion-reaction process are explicitly derived from a generalized spherical integral relation we prove both for two-dimensional and three-dimensional problems. The distribution of the exit position on the sphere has the form of the von Mises–Fisher distribution
which can be simulated efficiently. Rigorous expressions are derived in the case of constant velocity drift,
but the algorithm is then extended to solve drift-diffusion-reaction problems with arbitrary varying drift velocity vector.
The method can efficiently be applied to calculate the fluxes of the solution to any part of the boundary.
This can be done by applying a reciprocity theorem which we prove here for the drift-diffusion-reaction problems with general boundary conditions. Applications of this approach to methods of cathodoluminescence (CL) and electron beam induced current (EBIC) imaging of defects and dislocations in semiconductors are presented.
Local innovation systems in Poland - the beginning of the road
Authors: Dziemianowicz Wojciech , Laskowska Agnieszka , Peszat Klaudia 
Published: July 2017

AbstractLocal innovation systems (LIS) constitute a relatively new term as usually the discussion about the systemic approach to innovation has focused on the level of countries, and most of all - regions. In this article an attempt was made to assess Polish municipalities from the perspective of their potential for development of local innovative systems. The performed factor analysis allowed characterization of five types of institution networks which may impact creation and development of LIS. The study was completed with case studies in selected voivodeship cities as centres of the highest concentration of institutions usually building local innovation systems, three of which were capitals of the poorest regions in Poland.

Published: July 2017

Abstract
Two new group separation schemes, based on ion exchange chromatography, for the selective and quantitative isolation of rare earth elements (REE) from accompanying elements, were devised. After checking their performance with the aid of radioactive tracers, the schemes were further used together with ICP-MS, NAA and ion exchange chromatography for the determination of Sc, Y, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb and Lu in two certified reference materials (CRMs). The results were compared with another series of analyses, where the REEs were determined directly, i.e. without pre-separation, by instrumental neutron activation analysis (INAA) and inductively coupled plasma mass spectrometry (ICP-MS). It was demonstrated that while direct INAA and ICP-MS in most instances provide reliable results for the majority of REEs, for some elements, notably Sc, Yb and Tm in the cases of ICP-MS and INAA, respectively, systematic errors occur or may potentially occur.
A Woman Traveller in the Moorish Sanctum: A Look at Emily Keene, Shareefa of Wazzan’s My Life Story
Authors: Aammari Lahoucine 
Published: July 2017

Abstract
Emily Keene’s My Life Story (1911) is a unique travel account as it is written by an Englishwoman, which puts the travelogue in the ambit of female travel narratives. She married a Moorish notable, Sidi Al-Hadj Abd al-Salam, the Shareef of Wazzan, spending, hence, more than four decades amongst the Moors in pre-protectorate Morocco or the “Land of the Furthest West”. For more than four decades, Keene managed to live on the cusp of two starkly different cultures, civilizations, religions and societies. Keene was fascinated by the atavistic Moroccan customs and the metaphysical world of the Moors. The man she married epitomized these purely aspired elements. Keene was mesmerized and enchanted by the Moors, their culture and traditions, but at the same time she adhered to her own culture, moving, hence, between two acutely different identities. As an Englishwoman in the Moorish sanctum, Keene was virtually seen by most of the Moors as a Christian from “Bilad al-Nassara” or an “Abode of Disbelief”.
William Golding’s Apocalyptic Vision in Lord of the Flies and Pincher Martin
Authors: Chatterjee Arnab 
Published: July 2017

Abstract
Humanity has long been haunted by the notions of Armageddon and the coming of a Golden Age. While the English Romantic poets like Shelley saw hopes of a new millennium in poems like “Queen Mab” and “The Revolt of Islam”, others like Blake developed their own unique “cosmology” in their longer poems that were nevertheless coloured with their vision of redemption and damnation. Even Hollywood movies, like The Book of Eli (2010), rehearse this theme of salvation in the face of imminent annihilation time and again. Keeping with such trends, this paper would like to trace this line of apocalyptic vision and subsequent hopes of renewal with reference to William Golding’s debut novel Lord of the Flies (1954) and his Pincher Martin (1956). While in the former, a group of young school boys indulge in violence, firstly for survival, and then for its own sake, in the latter, a lonely, shipwrecked survivor of a torpedoed destroyer clings to his own hard, rock-like ego that subsequently is a hurdle for his salvation and redemption, as he is motivated by a lust for life that makes him exist in a different moral and physical dimension. In Lord of the Flies, the entire action takes place with nuclear warfare presumably as its backdrop, while Pincher Martin has long been interpreted as an allegory of the Cold War and the resultant fear of annihilation from nuclear fallout (this applies to Golding’s debut novel as well). Thus, this paper would argue how Golding weaves his own vision of social, spiritual, and metaphysical dissolution, and hopes for redemption, if any, through these two novels.
Literature and Learning in Marilynne Robinson’s Novel Gilead
Authors: Hricková Mária 
Published: July 2017

AbstractLiterature and learning play an important role in Marilynne Robinson’s Pulitzer Prize-winning novel Gilead (2004). By focusing on the author’s many references to books, literature and learning, the present paper attempts to study their individual contextual occurrences and explores how they saturate the discursive substratum of the novel’s major themes. The paper claims that a special role attributed to books and learning, and particularly to the Greek New Testament, The Trail of the Lonesome Pine and The Essence of Christianity, sheds significant light on the philosophical and spiritual aspects of the meaning of life, one of the novel’s central concerns.
Healing Trauma and Reasserting Identity through Remembrance in Joanne Fedler’s The Dreamcloth
Authors: Abdullah Md Abu Shahid 
Published: July 2017

AbstractThe aim of this article is to analyse the role of memory in generating, transmitting and coming to terms with trauma, and the importance of exploring history, and talking about and sharing traumatic events in the process of healing in Joan Fedler’s The Dreamcloth (2005). In the novel, Maya’s memories of her unrequited lesbian relationship with her beloved Rochel, oppression by the traditional structures of her family and Jewish community, her forced marriage with Yankel, and her being raped by him are responsible for her trauma on a personal level, whereas her forced relocation to South Africa in order to flee from the Holocaust is responsible for her trauma on a communal level. Mia, the protagonist and the grand-daughter of Maya, suffers from the transgenerational trauma of her grandmother, is haunted by her ghost, and also symbolically represents the traumatized Jewish community. She cannot relate to her own Jewish South African identity and thus tries to avoid being reminded of her historical background. Mia recovers from her trauma by exploring her history, solving the riddles of the past and sharing the traumatic memories of the past.
Dodging the Literary Undertaker – Biographic Metafiction in Hanif Kureishi’s The Last Word
Authors: Chalupský Petr 
Published: July 2017

Abstract
Hanif Kureishi’s 2014 novel, The Last Word, involves most of the author’s idiosyncratic themes, such as ethnicity, racism, sexual identity, examination of interpersonal relationships and the crucial role of the creative imagination in human life. Its focal concern, however, is to explore the process of writing a literary biography of a living person and the character and dynamics of the relationship between the biographer and his subject - a writer. As such, the novel can be taken as being representative of biographic metafiction, a subcategory of historiographic metafiction, which, following the postmodernist questioning of our ability to know and textually represent historical truth, presents biographic writing critically or even mockingly, rendering its enthusiastic practitioners’ efforts with ironic scepticism. The aim of this article is to present The Last Word as a particular example of biographic metafiction that has all the crucial features of this genre, yet which differs from its predecessors through the complexity and thoroughness of its portrayal of the biographer-biographee relationship.
Hatha Yoga as a Form of Physical Activity in the Context of Lifestyle Disease Prevention
Authors: Grabara Małgorzata 
Published: July 2017

Abstract
Physical activity is interrelated with health, physical fitness, and quality of life. The role physical activity plays in the context of lifestyle disease prevention is indisputable. Physical exercises of yoga (hatha yoga) are a type of recreational physical activity classified as a form of body and mind fitness. Hatha yoga training consists of slow or fast and smooth entering into, holding, and exiting yoga postures called “asanas”. Besides asanas, a yoga class may also include breathing exercises (pranayama) and relaxation exercises. The aim of this paper is to analyse the benefits of regular hatha yoga training in the light of scientific studies in regard to primary and secondary prevention of lifestyle diseases (cardiovascular diseases, respiratory system diseases, type 2 diabetes, obesity, and diseases of the musculoskeletal system in particular). The results of the analysis revealed that regular hatha yoga training including pranayama (breathing exercises) produced a reduction in blood pressure and heart rate, improved respiratory functions, decreased blood glucose levels and body mass, as well as improving functional fitness and self-perceived quality of life. Therefore, hatha yoga as a form of physical activity can be a useful intervention for primary and secondary prevention of cardiovascular diseases, respiratory system diseases, metabolic diseases, and diseases of the musculoskeletal system, including back pain.
Experimental and Numerical Investigation of Towing Resistance of the Innovative Pneumatic Life Raft
Authors: Burciu Zbigniew , Abramowicz-Gerigk Teresa , Jachowski Jacek , Kornacka Edyta , Wawrzusiszyn Michał 
Published: July 2017

Abstract
The paper presents the experimental and numerical investigations of a novel design of a pneumatic life raft in calm water conditions. Two main issues were considered: the life raft performance under tow and its resistance in calm water conditions. The experiment and CFD simulations were performed by using the full scale prototype to eliminate the scale effect. The towing tank tests confirmed the results of numerical computations. The compatibility of the results of numerical and experimental tests was high mainly because the new life raft does not deform under the hydrodynamic and aerodynamic loads. The characteristics similar to rigid body behaviour result mainly from a new construction and materials used for manufacturing the life raft.
Application of Intuitionistic Fuzzy Topsis Model for Troubleshooting an Offshore Patrol Boat Engine
Authors: Aikhuele Daniel Osezua , Sorooshian Shahryar , Ansah Richard Hannis , Turan Faiz Mohd 
Published: July 2017

AbstractIn this paper, an Intuitionistic Fuzzy TOPSIS model which is based on a score function is proposed for detecting the root cause of failure in an Offshore Boat engine, using groups of expert’s opinions. The study which has provided an alternative approach for failure mode identification and analysis in machines, addresses the machine component interaction failures which is a limitation in existing methods. The results from the study show that although early detection of failures in engines is quite difficult to identify due to the dependency of their systems from each other. However, with the Intuitionistic Fuzzy TOPSIS model which is based on an improved score function such faults/failures are easily detected using expert’s based opinions.
Variant Designing in the Preliminary Small Ship Design Process
Authors: Karczewski Artur , Kozak Janusz 
Published: July 2017

Abstract
Ship designing is a complex process, as the ship itself is a complex, technical multi-level object which operates in the air/water boundary environment and is exposed to the action of many different external and internal factors resulting from the adopted technical solutions, type of operation, and environmental conditions. A traditional ship design process consists of a series of subsequent multistage iterations, which gradually increase the design identification level. The paper presents problems related to the design of a small untypical vessel with the aid of variant methodology making use of optimisation algorithms. The computer-aided design methodology has been developed which does not need permanent reference to already built real ships and empirical-statistical relations. Possibilities were indicated for integrating together early design stages, and parallel designing of hull shape and parameters.
Using ZMET for Investigating the Role of Social Media in the Employment Process
Authors: Danileț Magdalena , Stoian Claudia 
Published: July 2017

Abstract
The purpose of this paper is to explore the role of social media in the employment setting as it is perceived by the job seekers. The study is a qualitative investigation in which thirteen in-depth interviews based on Zaltman Metaphor Elicitation Technique (ZMET) were conducted in order to gain a deeper understanding of the link between social media and the process of employment. The 22 elicited bipolar constructs associated with the role of social media in the employment setting were framed into six deep metaphors: Connection, Resource, Journey, Control, Affective Distress and Transformation. The size of the sample and the deeply subjective nature of answers provided by the subject’s limits the generalization of the results for a wider range of job seekers in the social media environment. This research provids an insight into deep-seated motivations, attitudes and behaviors involved in the use of social media by job seekers.
Foreign Exchange Market Efficiency In Botswana
Authors: Matebejana Gofaone , Motlaleng Gaotlhobogwe , Juana James 
Published: July 2017

AbstractThe random walk behaviour of exchange rates in Botswana’s foreign exchange market is explored by employing unit root tests. The unit root tests employed include the ADF, PP and the KPSS. This paper uses monthly data for the period 2000:01 to 2015:12. The conclusive evidence based on the unit roots tests indicates that the behaviour of the Pula against the South African Rand, Japanese Yen and the American Dollar exchange rates is consistent with the random walk process and the weak form efficiency market hypothesis. However, the Pula against the British Pound is inconsistent with the weak form efficiency market hypothesis. These results compliment those from Namibia (Mabakeng and Sheefeni, 2014). Furthermore, there is no evidence of the semi-strong form level of efficiency as revealed by the cointegration results obtained. These results corroborates with those found by Wickremasinghe (2008) and Çiçek (2014) in which weak form was found to exist whilst the semi-strong form was found not to exist. This paper has filled an important gap as it is the first study to investigate the efficiency of the foreign exchange market in Botswana.
A Newton-type method for non-linear eigenproblems
Authors: Demyanko Kirill V. , Nechepurenko Yuri M. , Sadkane Miloud 
Published: July 2017

Abstract
This work is devoted to computations of invariant pairs associated with separated groups of finite eigenvalues of large regular non-linear matrix pencils. It is proposed to combine the method of successive linear problems with a Newton-type method designed for partial linear eigenproblems and a deflation procedure. This combination is illustrated with a typical hydrodynamic spatial stability problem.
The structure and stabilization by boundary conditions of an annular flow of Kolmogorov type
Authors: Kornev Andrei A. 
Published: July 2017

Abstract
A system of Navier-Stokes equations with a right-hand side is considered in the case when the system approximately describes the motion of a thin layer of a viscous incompressible fluid in an annular domain under the action of external electromagnetic force. The problem possesses an unstable two-stream nonstationary main flow and a set of quasistationary solutions of vortex type for the tested range of parameters. A method of study of the general dynamic pattern is proposed in the paper. The method is based on the construction of control boundary conditions specified on the internal boundary of the annulus and providing the stabilization of considered unstable modes. The problem of boundary stabilization of the main and secondary flows is also solved numerically and we obtained that it is sufficient to take into account only a part of unstable modes in the construction of stabilizing conditions for the main flow. The method based on the partial stabilization of the main flow is first proposed for stabilization of secondary flows, which essentially simplifies the implementation of the algorithm. Formulations of the problems and numerical algorithms are presented.
A posterioriestimates for a coupled piezoelectric model
Authors: Langer Ulrich , Repin Sergey , Samrowski Tatiana 
Published: July 2017

AbstractThe paper is related to a coupled problem describing piezoelectric effects in an elastic body. For this problem, we deduce majorants of the distance between the exact solution and any approximation in the respective energy class of functions satisfying the boundary conditions. The majorants are fully computable and do not contain mesh dependent constants. They vanish if and only if an approximate solution coincides with the exact one and provide guaranteed upper bounds of errors in terms of the natural energy norm associated with the coupled problem studied.
