Robust Schemes Based on the Method of Lines for Shock Capturing
Authors: Mousa Mohamed M. 
Published: January 2019

Abstract
In this paper, the solution of nonlinear hyperbolic conservation law problems containing strong shock waves is presented using the method of lines. A difficulty with the method of lines, as with many other classical shock-capturing methods, is the threat of unphysical numerical oscillations, which can be avoided by adding an artificial viscosity term. Two schemes of the method of lines for solving the described problems have been proposed. Extensive numerical examples in both scalar and system test problems demonstrate the efficiency, robustness, and ease of implementation of the proposed schemes.

Published: January 2019

Abstract
Recent research has led to a point where a substantial number of industrial by-products with pozzolanic behavior can be used along with ordinary portland cement (OPC) without compromising the desired mechanical and durability properties. Literature reveals that fly ash, which is typically processed by burning ground coal in power plants, can easily replace up to 30–40 % of OPC, depending on its amorphous reactivity content, particle size, and loss on ignition content. The aim of this article is to determine the optimum amount of fly ash to be used as a critical factor for structural-grade concrete. A computational mathematical model is formulated using an artificial intelligence (AI) approach, such as an automated neural network search (ANS) modeling to explore the influence of mix designs on concrete compressive strength at 28 days. A total of 69 mixes were selected for formulation of the ANS model so that it could have decent precision, accuracy, and robust computing. The formulated computational ANS model was able to capture the complex relationship between compressive strength and different mix design parameters. Among all, percentage of fly ash was found to have the highest impact on 28-day strength development in high-volume fly ash concrete. The developed AI-based ANS model can be useful to researchers to accurately predict the mix design components for a structural-grade concrete. It can also be further improved by optimizing parameter setting in the network algorithm.
Forming Limit Diagram Prediction of AISI 304–St 12 Tailor Welded Blanks Using GTN Damage Model
Authors: Safdarian Rasoul 
Published: January 2019

Abstract
Because of weight and manufacturing cost decrease, tailor welded blanks (TWBs) have great usage in different industries such as the automotive and aircraft industries. Despite the wide use of TWBs in various industries, there are some drawbacks in the formability of these blanks. Using a forming limit diagram (FLD) enables one to prevent necking and fracture of these blanks by correct selection of forming parameters. There are different numerical methods to predict the FLD of sheet metals, but the Gurson–Tvergaard–Needleman (GTN) model is a useful ductile fracture model in this field. In this study, the GTN model was used for FLD prediction of AISI 304–St 12 TWBs. An anti-inference method and a numerical simulation of the tensile test by ABAQUS software (Dassault Systèmes, Vélizy-Villacoublay, France) were firstly used for GTN parameter identification of AISI 304 and St 12 blanks. Proper parameters of the GTN model were imported to the numerical tests of FLD, which was done based on the Nakazima standard test. In the experimental part of this study, carbon dioxide laser welding was used for TWBs welding, which consists of AISI 304 and St 12 blanks with equal thicknesses of 1 mm. The numerical results were compared for FLD prediction, punch’s load-displacement curve, and the fracture position of samples with experimental ones. The results showed that there was a good agreement between the numerical prediction and the experimental results.

The discourse of information warfare, challenges posed by adverse propaganda and political declarations about the need to protect the society from misleading information all create favorable conditions for new research on brainwashing. This article examines the new wave of studies on brainwashing, which emerged at the turn of the 21st century. An analysis of the historical context of brainwashing encourages the investigation of competitive concepts and reminds us of the negative scientific attitude toward brainwashing from the moment of its inception. The concept of brainwashing is examined as a mature conspiracy theory, which functions on three levels: the primary (or spontaneous), elite initiated (or official) and secondary (or mirror) levels. The principle aim of this article is to reveal the reasons behind the communicative vitality of brainwashing and to disclose the risks posed to democracy, which are created with the misuse of conspiracy theories and similar concepts.
Authenticity and Provenance in Long-Term Digital Preservation: Analysis of the Scope of Content

Published: January 2019

[full article, abstract in English; abstract in Lithuanian]
Authenticity is a fundamental issue for the long-term preservation of digital objects; however, the validation of authenticity is a complex task – it requires the representation of provenance as a precondition for trust. For that matter, it is crucial to define the key conceptual elements that provide the foundation for such a complex framework. The main objective of this paper is to define how authenticity has to be managed in the digital preservation process: to identify the semantic units needed to support core preservation functions in order to ensure the trustworthiness of digital objects and ensure interoperability – i.e., the ability to exchange data between institutions. This paper presents results from the first stage of the research: the scope of authenticity and provenance content needed to support core preservation functions and ensure interoperability – the ability to exchange data between institutions and assess the added value of the Europeana and VEPIS regarding authenticity and provenance based on the adequacy of analyzed international models for authenticity and provenance.Methodology: by applying the EU 2–3–6 concept of added value for electronic publishing and qualitative content analysis of research literature, we conceptualized the Content Creation Process, which refers to the structure and meaning of authenticity and provenance. This approach enabled us to identify the scope of the content of authenticity and provenance.
The Impact of Financial Development on Investment: A Review of International Literature
Authors: Muyambiri Brian , Odhiambo Nicholas M. 
Published: January 2019

[full article and abstract in English]
This article summarises the empirical literature on the impact of financial development on investment. It presents a topical analysis of empirical research that focuses mainly on the interaction between financial development and investment, determinants and measurement of both financial development and investment, and empirical findings on the relationship between the two variables under discussion. The study concludes that most of the research done on the relationship between financial development and investment is highly skewed towards assessing the relationship using mostly bank-based financial development indicators, as compared to the market-based financial development indicators. Given the number of studies assessed, the impact of financial development on investment appears to be inconclusive, at best. Moreover, the study shows that the relationship between these two macroeconomic variables seems to differ from country to country; it is dependent on the proxies used to measure the level of financial development, as well as the methodology employed.

This article analyzes whether the Drawing Test for Creative Thinking (TCT-DP) can be applied as a reliable and valid instrument for the assessment of the creative potential of 8–10-year-old Lithuanian children. Currently in Lithuania, there is no such test for this particular age. Empirical and theoretical research shows that the developmental pace and structure of creative potential among children of primary school age may be specific (Urban, 1991; Rudowicz, 2004; Lubart et al., 2010; Ju et al., 2015; Jastrzębska & Limont, 2017; Welter et al., 2017). The study consisted of 497 primary pupils across grades 2–4. The quota sample was based on the criteria of a child’s age, gender, and school location. All children are assessed by A and B forms of TCT-DP; the Wechsler’s Intelligence Scale for Children (WISC-IIILT) was administered to 63 randomly selected children for the purpose of verifying discriminant validity. The SPSS Statistics 25 software package was used for data analysis. The results revealed a significant difference in the creative potential among children of age 8 and age 10; the results for girls and boys were similar. The evaluation of several types of reliability had shown good or excellent inter-rater reliability, the accuracy of the categories rating system, minimally sufficient stability of the aggregate score of A and B forms, and an inadequate internal consistency of these forms. Both A and B forms equally well differentiated the level of children’s creativity. The TCT-DP construct validity
was confirmed by the stable increase of performance of 8-year-olds, 9-year-olds and 10-year-olds. Exploratory factor analysis has highlighted that the creative potential of children aged 8–10 years is best described by three factors – Originality, Adaptability and Risk taking. That generally consists with the findings of other researchers (Rudowicz, 2004; Lubart et al., 2010) that emphasize originality, nonconventionality
on the one hand, and adaptation to the requirements on the other hand. However, it is difficult to consistently match these results with the original data on TCT-DP, as Urban and Jellen (1995) performed a factor analysis in a joint sample of 4–16-year-old children. Low correlations with the WISC-IIILT results confirm the discriminant validity of TCT-DP.
El sueño de la “Nación católica”: el golpe de Estado de 1943 y la Iglesia argentina. Una mirada desde el obispado de Leopoldo Buteler (Río Cuarto, 1943-1946)
Authors: Camaño Semprini Rebeca Raquel 
Published: January 2019

El golpe de Estado de 1943 fue recibido con beneplácito por la Iglesia argentina, pues implicó la posibilidad de implementar el proyecto de “Nación católica” impulsado desde la década anterior. En la provincia de Córdoba vino a poner fin, además, a una experiencia política caracterizada por un perfil laicista y respetuoso de la libertades públicas, incluso del comunismo. En el presente artículo analizamos las relaciones entre el obispado de Río Cuarto (que abarcaba la mitad meridional de la provincia e incluía la segunda ciudad cordobesa en importancia poblacional, política y económica) y las autoridades militares que dirigieron los destinos de la provincia entre 1943 y 1946. El propósito es demostrar, a través de una reducción de la escala de análisis, cómo durante estos años se produjo una simbiosis entre Iglesia y Ejército en la construcción de un proyecto político estructurado en torno a la identidad católica. Para ello recurrimos a una metodología cualitativa, basada fundamentalmente en el análisis tanto de periódicos locales y provinciales de la época como de fuentes internas a la institución eclesiástica.
El universo espiritual humano en los textos de José Martí de La opinión nacional
Authors: Varona Domínguez Freddy 
Published: January 2019

Ante la urgencia de atender a los problemas cuya solución no es solo material, el universo espiritual humano se presenta como una categoría central. Al conjugar lo racional y lo afectivo, se delimita su esencia, asimismo se despliega una reflexión teórica y se revela su presencia en el pensamiento de José Martí. Se estudian sus es- critos de 1881-1882 en el diario caraqueño La Opinión Nacional, hasta ahora poco analizados, para mostrar la relación dialéctica en la visión unitaria e integradora, así como sus consideraciones sobre el universo espiritual humano.
Self-reported addiction to pornography in a nationally representative sample: The roles of use habits, religiousness, and moral incongruence
Authors: Grubbs Joshua B. , Kraus Shane W. , Perry Samuel L. 
Published: January 2019

Background and aims
Despite controversies regarding its existence as a legitimate mental health condition, self-reports of pornography addiction seem to occur regularly. In the United States, prior works using various sampling techniques, such as undergraduate samples and online convenience samples, have consistently demonstrated that some pornography users report feeling dysregulated or out of control in their use. Even so, there has been very little work in US nationally representative samples to examine self-reported pornography addiction.

Methods
This study sought to examine self-reported pornography addiction in a US nationally representative sample of adult Internet users (N = 2,075).

Results
The results indicated that most participants had viewed pornography within their lifetimes (n = 1,461), with just over half reporting some use in the past year (n = 1,056). Moreover, roughly 11% of men and 3% of women reported some agreement with the statement “I am addicted to pornography.” Across all participants, such feelings were most strongly associated with male gender, younger age, greater religiousness, greater moral incongruence regarding pornography use, and greater use of pornography.

Discussion and conclusion
Collectively, these findings are consistent with prior works that have noted that self-reported pornography addiction is a complex phenomenon that is predicted by both objective behavior and subjective moral evaluations of that behavior.

The publication of the Common Euro- pean Framework of Reference for Languages, in the year 2001, brought about a new methodological concept, known as the action-oriented approach, which has spread widely among practically all the participants involved in second language acquisition (from researchers and teachers to trainers, learners included). In 2017, 16 years af- ter its publication, the Council of Europe publis- hed the Companion Volume with New Descriptors. Some new aspects have been further reformu- lated following the practitioners’ demand; espe- cially those connected with the development of descriptors showing original illustrative scales and with the de nition of some key principles found in the original 2001 document.There was also a substantial reconsideration of the most appropriate methodology for second langua- ge teaching, among other points. In light of the antecedents of the action-oriented approach and the opinions both for and against its singularity, the present paper analyses the de nition and the fundamentals that this new document provides about this framework.This paper intends to co- rroborate its similarity with other approaches as we suggested in a previous paper– or, on the contrary, its originality and differentiating status.

However, this enormous role is not matched by a mature debriefing of these two compe-tencies for the preparation of a professional teacher candidate. Of the 163 SKSs studied, only 26 credits were granted to form social competence and personality. Means only 16% of the propor-tion of courses for these two competencies. So on this, it needs an independent but planned effort to improve the social competence and personality of teachers, such as through pengajian pro-grams for teachers in schools. This article is formulated by using the reseacrh library approach.

Three-dimensional Reduced-Complexity Simulation of Fluvio-Deltaic Clastic Stratigraphy
Authors: Falivene Oriol , Frascati Alessandro , Bolla Pittaluga Michele , Martin John 
Published: January 2019

Abstract
A novel reduced-complexity approach to 3D forward modeling of siliciclastic stratigraphy is presented for the simulation of erosion, transport, and sedimentation in continental, transitional, and marine depositional domains. The numerical model is based on defining centerlines that connect sediment input points to the shoreline. For each centerline, erosional and depositional surfaces bound depositional domains, and sand and mud proportions are assigned to each domain. The position of each depositional surface follows a set of geologic rules and ensures mass balance with sediment input. The numerical model is tested by simulating the basin-fill architecture of the XES02 laboratory experiment run at the University of Minnesota, which generates stratigraphy mimicking a passive-margin basin fill. Automatic calibration is used to test multiple combinations of uncertain model input parameters to find those that produce scenarios consistent with the experimental stratigraphy.
Calibrated models accurately reproduce shoreline and mass-balance centroid migration, marine sediment proportions, and shoreline trajectories measured in the XES02 experiment. The models also provide reasonable approximations of sand distribution. Of interest, falling shoreline trajectories in the experiment and the calibrated models develop coeval to topset aggradation or topset incision depending on rate of base-level fall. The results reported herein validate the numerical approach for simulating sand distribution in an experimental basin, representing a first step towards the application of the numerical model in fluvio-deltaic settings. For field applications, analogue data can be used to independently constrain the geometry of surfaces bounding depositional domains and their composition. The simplicity of the numerical model then enables multiple realizations by quickly varying uncertain boundary conditions, allowing probabilistic predictions in settings with limited data constraints.
Influence of Frictional or Rotational Kinetic Energy on Wellbore-Fluid/Temperature Profiles During Drilling Operations
Authors: Al Saedi A. Q. , Flori R. E. , Kabir C. S. 
Published: January 2019

Summary
Temperature-profile distributions in a wellbore during drilling operations might take different forms when applying the energy balance in the overall system. For steady-state conditions, wherein the wellbore is considered a closed system, adding any source of additional energy to this system can influence the predicted temperature profiles. This study presents a new analytical model to investigate the influence of rotational energy arising from the drillstring operation on the wellbore-temperature behavior.
A significant part of the drilling operation is rotation of the drillstring. Depending on the drilling rig, various equipment provides this kind of energy, such as the rotary table or topdrive. In addition, downhole motors or turbines can add additional rotation to the drill bit. This type of energy source can be construed as a supplemental heat source that could be added to the formulations of drillpipe- and annular-temperature profiles.
Overall, this study presents two models involving frictional and rotational energy. These models yield the same solution if we do not include the energy source, and they can apply equally well for any energy-balance system. The proposed mathematical models provide new insights into different energy terms that can be included to compute the temperature profiles in the drillpipe and annulus.
