«Vida de este capitán», de Alonso de Contreras (introducción de Ismael López Martín)
Authors: Escalante Varona Alberto 
Published: March 2019

Reseña del libro Vida de este capitán, de Alonso Contreras (introducción de Ismael López Martín, Colección Penguin Clásicos, Barcelona, Penguin Random House, 2018).
La Vida de este capitán vuelve a editarse bajo el sello de Penguin Random House. Para ello, se reimprime la edición que ya apareció publicada en 2008, en la editorial Reino de Redonda; texto que Penguin recuperó y aprovechó posteriormente, en 2012, para otra impresión prologada por Arturo Pérez-Reverte. Por tanto, nos encontraríamos con la tercera ocasión en que el sello publica las memorias del capitán Contreras en diez años. El principal motivo es, sin duda, comercial, para así ampliar el catálogo de la colección Penguin Clásicos con uno de los textos fundamentales de la literatura autobiográfica española. Pero la editorial no pierde la ocasión de darle un lavado de cara a la edición para incluir en ella una novedad que refuerce su inclusión en la colección. Siguiendo el objetivo principal de Penguin Clásicos, Vida de este capitán se presenta en una edición de bolsillo, asequible en formato y precio, pensada más en la lectura por placer que en la consulta erudita; pero no por ello falta de un breve estudio introductorio y un aparato de notas en el que se destaquen los principales rasgos temáticos y compositivos del texto. La responsabilidad de esta introducción, que no prólogo (al contrario que en las reimpresiones anteriores en Penguin Random House), recae en Ismael López Martín: doctor internacional en Estudios Lingüísticos Filológicos y Lingüísticos por la Universidad de Extremadura y con experiencia docente en la Universidad de Zaragoza. López vuelve a colaborar con Penguin Clásicos, para quienes ya preparó una nueva edición de Don Juan Tenorio, publicada en 2017.
Solutions and conservation laws of a generalized second extended (3+1)-dimensional Jimbo-Miwa equation
Authors: Daddy Moleleki Letlhogonolo , Motsepa Tanki , Masood Khalique Chaudry 
Published: March 2019

Abstract
In this paper we study a nonlinear multi-dimensional partial differential equation, namely, a generalized second extended (3+1)-dimensional Jimbo-Miwa equation. We perform symmetry reductions of this equation until it reduces to a nonlinear fourth-order ordinary differential equation. The general solution of this ordinary differential equation is obtained in terms of the Weierstrass zeta function. Also travelling wave solutions are derived using the simplest equation method. Finally, the conservation laws of the underlying equation are computed by employing the conservation theorem due to Ibragimov, which include conservation of energy and conservation of momentum laws.
Review of numerical methods for NumILPT with computational accuracy assessment for fractional calculus
Authors: Brzeziński Dariusz W. 
Published: March 2019

Abstract
In the paper we present results of accuracy evaluation of numerous numerical algorithms for the numerical approximation of the Inverse Laplace Transform. The selected algorithms represent diverse lines of approach to this problem and include methods by Stehfest, Abate and Whitt, Vlach and Singhai, De Hoog, Talbot, Zakian and a one in which the FFT is applied for the Fourier series convergence acceleration. We use C++ and Python languages with arbitrary precision mathematical libraries to address some crucial issues of numerical implementation. The test set includes Laplace transforms considered as difficult to compute as well as some others commonly applied in fractional calculus. Evaluation results enable to conclude that the Talbot method which involves deformed Bromwich contour integration, the De Hoog and the Abate and Whitt methods using Fourier series expansion with accelerated convergence can be assumed as general purpose high-accuracy algorithms. They can be applied to a wide variety of inversion problems.
Benefits of a dance group intervention on institutionalized elder people: a Bayesian network approach
Authors: Navarro-Pardo E. , González-Pozo L. , Villacampa-Fernández P. , Conejero J.A. 
Published: March 2019

Abstract
The present study aims to explore the effects of an adapted classical dance intervention on the psychological and functional status of institutionalized elder people using a Bayesian network. All participants were assessed at baseline and after the 9 weeks period of the intervention. Measures included balance and gait, psychological well-being, depression, and emotional distress.
According to the Bayesian network obtained, the dance intervention increased the likelihood of presenting better psychological well-being, balance, and gait. Besides, it also decreased the probabilities of presenting emotional distress and depression. These findings demonstrate that dancing has functional and psychological benefits for institutionalized elder people. Moreover it highlights the importance of promoting serious leisure variety in the daily living of institutionalized elder adults.
The high accuracy conserved splitting domain decomposition scheme for solving the
parabolic equations
Authors: Zhou Zhongguo , Li Lin 
Published: March 2019

Abstract
In this paper, the high accuracy mass-conserved splitting domain decomposition method for solving the parabolic equations is proposed. In our scheme, the time extrapolation and local multi-point weighted average schemes are used to approximate the interface fluxes on interfaces of sub-domains, while the interior solutions are computed by one dimension high-order implicit schemes in sub-domains. The important feature is that the developed scheme keeps mass conservation and are of second-order convergent in time and fourth-order convergent in space. Numerical experiments confirm the convergence.
Predecessors and Gardens of Eden in sequential dynamical systems over directed graphs
Authors: Aledo Juan A. , Diaz Luis G. , Martinez Silvia , Valverde Jose C. 
Published: March 2019

Abstract
In this work, we deal with the predecessors existence problems in sequential dynamical systems over directed graphs. The results given in this paper extend those existing for such systems over undirected graphs. In particular, we solve the problems on the existence, uniqueness and coexistence of predecessors of any given state vector, characterizing the Garden-of-Eden states at the same time. We are also able to provide a bound for the number of predecessors and Garden-of-Eden state vectors of any of these systems.
A theoretical model for the transmission dynamics of HIV/HSV-2 co-infection in the presence of poor HSV-2 treatment adherence
Authors: Mhlanga A. 
Published: March 2019

Abstract
Herpes simplex virus (HSV-2) triples the risk of acquiring human immunodeficiency virus (HIV) and contributes to more than 50% of HIV infections in other parts of the world. A deterministic mathematical model for the co-interaction of HIV and HSV-2 in a community, with all the relevant biological detail and poor HSV-2 treatment adherence is proposed. The threshold parameters of the model are determined and stabilities are analysed. Further, we applied optimal control theory. We proved the existence of the optimal control and characterized the controls using Pontryagin’s maximum principle. The controls represent monitoring and counselling of individuals infected with HSV-2 only and the other represent monitoring and counselling of individuals dually infected with HIV and HSV-2. Numerical results suggests that more effort should be devoted to monitoring and counselling of individuals dually infected with HIV and HSV-2 as compared to those infected with HSV-2 only. Overall, the study demonstrate that, though time dependent controls will be effective on controlling HIV cases, they may not be sustainable for certain time intervals.
Solution of two point boundary value problems, a numerical approach: parametric difference method
Authors: Pandey P.K. 
Published: March 2019

Abstract
In this article, we have presented a parametric finite difference method, a numerical technique for the solution of two point boundary value problems in ordinary differential equations with mixed boundary conditions. We have tested proposed method for the numerical solution of a model problem. The numerical results obtained for the model problem with constructed exact solution depends on the choice of parameters. The computed result of a model problem suggests that proposed method is efficient.
Migration in Sub-State Territories with Historical-Linguistic Minorities: Main Challenges and New Perspectives
Authors: Medda-Windischer Roberta 
Published: March 2019

AbstractMigration is an important reality for many sub-national autonomous territories where traditional-historical groups (so-called ‘old minorities’) live such as Flanders, Catalonia, South Tyrol, Scotland, Basque Country, and Quebec. Some of these territories have attracted migrants for decades, while others have only recently experienced significant migration inflow. The presence of old minorities brings complexities to the management of migration issues. Indeed, it is acknowledged that the relationship between ‘old’ communities and the ‘new’ minority groups originating from migration (so-called ‘new minorities’) can be rather complicated. On the one hand, interests and needs of historical groups can be in contrast with those of the migrant population. On the other hand, the presence of new minorities can interfere with the relationship between the old minorities and the majority groups at the state level and also with the relationship between old minorities and the central state as well as with the policies enacted to protect the diversity of traditional groups and the way old minorities understand and define themselves. The present lecture analyses whether it is possible to reconcile the claims of historical minorities and of new groups originating from migration and whether policies that accommodate traditional minorities and migrants are allies in the pursuit of a pluralist and tolerant society.

Sequential parts create the mosaics of grid, with the following description of basic laws and principles in power systems.
A Survey of Broken Rotor Bar Fault Diagnostic Methods of Induction Motor
Authors: Asad Bilal , Vaimann Toomas , Rassõlkin Anton , Kallaste Ants , Belahcen Anouar 
Published: March 2019

Abstract
Electrical machines, induction motors in particular, play a key role in domestic and industrial applications. They act as a work horse in almost every industry and are responsible for a big proportion of total generated electricity consumption worldwide. The faults in induction motors are degenerative in nature and can lead to a catastrophic situation if not diagnosed earlier. The failures can cause considerable financial loss in the form of unexpected downtime. Broken rotor bar is a very common and frequently occurring fault in most of industrial induction motors. To select a better, more accurate and reliable fault diagnostic technique, this paper presents a comprehensive literature survey on the existing motor current signature analysis (MCSA) based fault diagnostic techniques. Different well-known MCSA based fault diagnostic techniques are summarized in the form of basic theories, considering complexity of their implementation, merits and demerits.
Phase Characteristics of Models of GaAs Gyroelectric Waveguides with Temperature Sensitive Anisotropic Dielectric Layers in Case of One Layer
Authors: Plonis Darius , Katkevičius Andrius , Belova-Plonienė Diana 
Published: March 2019

Abstract
Models of open cylindrical multilayer gyroelectric-anisotropic-gyroelectric waveguides are presented in this paper. The influence of density of free carriers, temperature and the presence of the external dielectric layer on the wave phase characteristics of the models of n-GaAs waveguides has been evaluated. Differential Maxwell’s equations, coupled mode and partial area methods have been used to obtain complex dispersion equation of the models of gyroelectric-anisotropic-gyroelectric waveguides with or without the temperature sensitive external anisotropic dielectric layer. The analysis has shown that the phase characteristics are practically unchanged when the density of electrons is equal to N = (1017–5·1018) m−3, d/r
s = 0, the changes of wave phase coefficients are obtained in the models of waveguides with the external anisotropic dielectric layer. The largest differences of wave phase coefficient are obtained when the density of electrons is N = 1021 m−3. The external dielectric layer improves the control of gyroelectric n-GaAs waveguides with temperature.
Design and Control of a STATCOM for Non-Linear Load Compensation: A Simple Approach
Authors: Tripathi Saurabh Mani , Barnawal Prakash Ji 
Published: March 2019

Abstract
This paper presents a systematic procedure to design a simple control for a three-phase VSC-based static synchronous compensator (STATCOM) in order to overcome the problems caused by the presence of the non-linear load at the point of common coupling (PCC). The proposed control method regulates the STATCOM in such a way that the source quadrature current component is forced to be zero so that only the active current component is drawn from the source and the harmonic and reactive current demands of the non-linear load are met by the STATCOM. The tuning of the inner and outer loop PI controllers is carried out with the help of the modulus optimum and symmetric optimum criteria, respectively. At last, a few case studies are presented using MATLAB simulation to exemplify the success of the proposed control method.
Country Branding: What Branding? Relevant Terminologies and their Possible Interpretations in the Case of Countries
Authors: Papp-Váry Árpád Ferenc 
Published: March 2019

Summary

Subject and purpose of work: The study systematizes concepts and terms related to country branding such as nation branding, state branding, place branding, destination branding, location branding, territory branding, and region branding as well as exploring the similarities and differences among these expressions.

Materials and methods: First of all, the study reviews relevant literature. In this context it also analyzes the most relevant country case study articles with titles that may include country branding or related terms in many forms.

Results: At the end of the study, a summary table systematizing the terminology of the topic is included, which is a novel approach to the subject. The practical significance of the study becomes clear if organizations involved in the development of country brands consider the abovementioned theoretical framework while developing their own strategies.

Conclusions: As a result of the systematization, country branding will be more consciously used in the subchapters of strategic materials discussing how to increase country competitiveness.
Opportunities and Barriers for Smart Rural Development in Poland in Light of Field Studies
Authors: Dudek Michał 
Published: March 2019

Summary

Subject and purpose of work: The paper focuses on identifying and assessing selected conditions and limitations of smart rural development in Poland. The concepts of smart development pointed out in the literature were used to analyse the results of field studies carried out in 2011 and 2016 in ten purposefully selected villages located in various regions of the country.

Materials and methods: The conclusions were drawn on the basis of empirical material which took a form of quantitative data and qualitative information gathered from the interviews with village mayors (sołtys) and observations of the interviewers. For the purpose of the paper the statistical methods were used and the analysis of the content of responses was performed.

Results and conclusions: The results of the surveys indicated a presence of both the potential of smart development in the surveyed villages and the barriers to it. The important determinants to activate local economic progress based on knowledge, education and new technologies were connected mainly with a convenient location and the environmental and cultural resources available. As for an insufficient level of valorisation of the aforementioned elements, it proved to be an obstacle to this process, which was largely due to the limited accumulation of human and social capital.
Protoeconomics - Elements of Economics in Antiquity
Authors: Wójcicki Włodzimierz 
Published: March 2019

Summary

Subject and purpose of work: The work presents the emergence and shaping of basic economic issues since the dawn of human economic activity. Contemporary views on important economic issues have their roots in antiquity. The shaping of concepts such as money, interest, contract, credit as a part of the law, began a long time ago and exerted an influence on the way they are understood today.

Materials and methods: The basis for the considerations is the study of literature on the history of the development of economics and the science of management in economic, philosophical and ethical aspects. The work has shown the non-linear nature of the development of new phenomena emerging in volatile political, technical, religious and moral conditions, which are largely spontaneous, and a reciprocal overlap of various fields of knowledge in a general and individual sense. Particular discoverers were found to present a wide spectrum of interests.

Results: Historically, the development of economic knowledge began with the issues from the border of economics and management, from microeconomics (household) to macroeconomics (money); little information concerns large undertakings such as irrigation systems, pyramids or waging wars.

Conclusions: Generally speaking - monarchs’ edicts came before the deliberations of thinkers, concrete reasoning came before abstract considerations.
Interlingválne A Intralingválne Súvislosti Ikonickosti A Arbitrárnosti Jazykového Znaku
Authors: Sabol Ján 
Published: March 2019

Abstract
The relation between the symmetry and the asymmetry of form and content in a language has become a basic stimulant of two central semiotic natures, „messages” of linguistic schemes: the iconic­symbolic (with symmetry of form and content; form is a part of reflectional area of the sign) and the arbitrary (with „inherited” symmetry of non­reflectional type of symmetry, but with a dominant asymmetry of form and content; form is not a part of reflectional area of the sign) semiotic principles, which closely – mostly through its elements – cooperate, supplement and regroup each other. In order to specify the relation between iconic­symbolic and arbitrary semiotic principles, it is necessary (mostly in contradiction with the connection between synchronicity and diachronicity, in particular through the viewpoint of motivation – non­motivation as a binary opposition) to analyse interlingual and intralingual relations of semiotic natures stated above. There is – according to the extent of proximity in linguistic schemes – a (largely) synchronous tendency of linguistic­semiotic units to be arbitrary in the interlingual area of the sign, and in their structuring the more intensive representation of (genetic) motivation as an „echo” of iconic linguistic „tonality” in the intralingual area of the sign. The combination of interlingual and intralingual connections between language units extends the penetration of relation between iconicity and arbitrariness in the language system.
Luče, Luče, Zlaté Lúče! Hviezdoslavovské Poznámky K Viacsmernosti Lexikálnej Dynamiky
Authors: Nábělková Mira 
Published: March 2019

Abstract
The literary texts of Pavol Országh Hviezdoslav contain a lot of lexical items unknown to contemporary readers. From anthropocentric point of view, these words as well as many other peripheral lexical items (i.e. obsolete and dialectal words, archaicisms and historicisms) in various texts of the earlier periods may be considered lexical agnonyms. In this connection, the occurrence of small dictionaries attached to the published books as a help for readers is particularly interesting. The appended dictionaries, originating in different periods as a specific kind of reduced text dictionaries, are worth attention from the point of view of Slovak and Slovak­Czech lexicography and from the viewpoint of the language policy and planning in support of Czech­Slovak and Slovak­Czech bilingualism and biliteracy.
О Развитии Периферийных Словообразовательных Категорий Русских И Польских Nomina Actionis В Эпоху Глобализации
Authors: Koriakowcewa Elena 
Published: March 2019

Abstract
The main objective of the study is to analyse and describe the structural organization and semantic and cognitive properties of new peripheral word­formation types of nomina actionis in the modern Russian and Polish languages. As resistant forms and organizing principles of the thinking process, the derivational categories of nomina actionis derivatives reproduce the properties and relations of being and knowledge in the most concentrated form. It increases the need for a comprehensive study of their structure and semantics. The article analyses the main approaches to the differentiation of the peripheral types of word­formation categories according to the nature of derivational semantics. The author justifies the nominative rendering of transposition and proves that it can contribute to distinguish a mixed type of word­formation categories.
Estimation of lowland river cross-section changes for different soils
Authors: Urbański Janusz , Oleszczuk Ryszard , Brandyk Andrzej , Zając Ewelina 
Published: March 2019

Abstract
This paper involves a comparative analysis of cross-sectional changes at selected reaches of a lowland river, flowing through the areas of mineral and organic soils. The comparisons were made at the background of design and execution assumptions from the period 1967–1971. Main processes, responsible for the observed changes of riverbeds in mineral soils (silting, conservation works) and organic soils (subsidence, disappearance of the peat deposit), were identified. In case of organic soils, the decrease of cross-sectional area by approximately from 30 to 60% was estimated in comparison to the original project assumptions, and the subsidence of river banks reached even 0.5 m in relation to the level determined in 1967. In the area of mineral soils, more considerable variability of cross-sectional area was noted along with minor changes of river banks elevation, that resulted most likely from the performed maintenance works.
