“NARRATIVE GEOMETRY”. ON THE METHOD FOR SUMMING ANGLES IN RUSSIAN ICONOGRAPHY
Authors:   Russian State University for the Humanities, Antonov Dmitriy I.
Published: May 2021

The article deals with the techniques of the moveable spectator position and summing up angles in Russian iconography. Those visual techniques, described by a number of researchers, pertain to the ‘basic grammar’ of post-iconoclastic Byzantine and medieval Russian art. Firstly, the sliding spectator position and the summation of the angles made it possible to show the depicted object simultaneously from several points of view – the icon-painter represented the visual figure in several mutually exclusive (with a fixed observer position) angles. The technique was used in Russian iconography primarily to demonstrate significant objects. Thus, in the space of the composition the creator of the image conveyed all the necessary information about the depicted object, saturating the picture with various semantic nuances and creating ‘micro-stories’. Less often the same technique could also be used to demonstrate peripheral objects. Secondly, the summation technique solved another task, demonstrating the dynamics of the character’s movement. In that case, it is not the painter who ‘moves’ (mentally examining the object from different positions), rather the hero of the visual story. Fixing different moments of time, the icon-painter transforms the depicted figure so that the character’s body freezes in an unnatural position. The position of the body conveys information about the direction of the movements of the hero depicted. The paper considers both typical and specific examples of the use of those techniques in medieval Russian art.
Encryption and Decryption of the Data by Using the Terms of the Lucas Series
Authors: GÜNEY DUMAN Merve , DUMAN Mehmet
Published: May 2021

The sequence, whose initial condition is 2 and 1, obtained by summing the two terms preceding it, is called the Lucas sequence. The terms of this series continue as 2, 1, 3, 4, 7, 11, 18, 29, ... respectively. The features of the Lucas sequence have been studied in many projects in the literature and many studies have been done on Lucas series in applied sciences. Cryptology is the science that deals with encrypting data, transferring it securely from one point to another, and converting the encrypted data to the previous one. It includes cryptography and cryptoanalysis. Different encryption-decryption methods have been developed to ensure the security of the data from the past to the present. Some of these are Caesar, Affine, Vigenere and RSA. There are two types of encryption systems in cryptology. The first one is symmetric (secret key) encryption and the another one is asymmetric (public key) encryption. In this study; using the features of the Lucas sequence, studies on cryptology, which deals with the correct encryption, transfer and decryption of data, have been carried out and an example of cryptology algorithm has been given. With Lucas cipher, the letters in the alphabet and the space character are each mapped to the terms of the Lucas sequence. Later, starting from the first term of the Lucas sequence, the encryption was strengthened by adding Lucas terms. As a result, the text to be encrypted has been turned into a symbolic representation of the numbers. Then, the necessary information for deciphering the text which is encrypted with numbers is given.

Ka mua, ka muri: navigating the future of design education by drawing upon indigenous frameworks
Authors: Waipara Zak
Published: May 2021

As design practitioners and educators attempt to respond to a shifting world– in the Māori language, Te Ao Hurihuri–how might we manage such changes? An indigenous precedent draws upon the past to assist the future: ka mua ka muri, ‘travelling backwards into the future,’ the past spread out behind us, as we move into the unknown. Indigenous academics draw inspiration from extant traditional viewpoints, reframing them as methodologies, using metaphor to shape solutions. What is it about the power of metaphor, particularly indigenous ways of seeing, that might offer solutions? In this paper, I describe explorations to extract guiding principles from Indigenous navigational knowledge. The goal: to construct a applicable structure for tertiary design teaching from two metaphorical models, based in Samoan and Hawaiian worldviews, and related Māori concepts. The result was a Navigator framework, created for potential use in a collaborative, studio-style classroom.
Processos de criação em moda: roupas desobedientes de André Lima
Authors: Dias Susanne Pinheiro
Published: May 2021

Este artigo estuda os processos de criação de uma série de roupas produzidas pela marca de moda brasileira André Lima para a temporada de verão (2005). Tais objetos são formados basicamente por uma superfície têx­til, marcada por buracos e/ou fendas de tamanhos variados. As peças não apresentam zonas de apoio no corpo nem zonas de passagem dos braços, do pescoço e/ou das pernas pré-determinadas – o que nos provoca a desauto­matizar nossos sentidos, gestos e pensamentos, acostumados com roupas prontas para vestir. Nesse sentido, o texto busca colaborar para uma reflexão sobre o papel político-cultural dos profissionais de moda, como propulsores de experiências de existência menos domesticadoras.
The recalibration of a design studio curriculum during COVID–19 in Aotearoa
Authors: Grieve Fiona
Published: May 2021

This article presents the impact COVID–19 had on a first-year communication design curricula revitalisation to progress students from a secondary level standards-based criterion to a tertiary culture predicated on active and experiential practice-led studio inquiry. Methodologically, it describes a design-based research intervention that asks what occurred in the translation of a brief written as an in-person, studio-based model into a purely online undertaking, learning from anywhere, teaching in a constant state of flux? Through a commentary on practice, the revitalisation of a design programme, and the pedagogical shift from within the traditional studio paradigm–a dynamic on-campus, in-person model into an abrupt and atypical online undertaking due to the global pandemic, this paper contributes to a discourse on a design studio approach and presents the transference of the Learning Management System that supports distance learning.

Evaluation of a new short-project based learning (PBL) method in an engineering 1st year programm
Authors: Nomani Junior , Littlefair Guy
Published: May 2021

A new novel approach towards Project Based Learning (PBL) was developed for design project-based learning activities. PBL activities traditionally span in duration from a few weeks to one year. The shortened PBL project was created for a half-day practical and ran in a 1st year undergraduate engineering unit. The project involved sustainable re-design of disaster- aid relief items. The project also involved students utilising interactive 3D virtual visualisation technology known as the CAVE environment as a design development tool. This paper assesses the effectiveness of the developed short project-based learning project (SPBL) at improving student engagement. Students survey responses indicated student engagement was high from participating in the short PBL activity, realism in the project played an important role. Short PBL projects can become a positive tool in teaching and learning through the maintaining of student and cognitive engagement throughout the entire duration of the project.

Tensiones de lo femenino/masculino en los espacios escriturales de Gabriela Mistral
Authors: Garcí­a Mendoza Francisco
Published: May 2021

En este ensayo se contrastan los espacios escriturales presentes en Gabriela Mistral. Se propone el poema "La otra" como una de las marcas que evidencian la esci.sión del yo, estableciendo de ese modo una escritura de carácter público y otra relegada al ámbito de lo privado. A partir de la propuesta anterior, se revisa la correspondencia con su albacea Doris Dana desde una perspectiva literaria, para hallar las marcas que confirmen la propuesta sugerida en el poema "La otra" y así­ intentar establecer las huellas de lo femenino y lo masculino en su escritura. La interpretación y lectura de su obra poética permite confirmar la impostación que utiliza Mistral para validarse en el canon poético nacional.

INSTITUTIONAL FACTORS OF ECONOMIC PERFORMANCE: EVIDENCE FROM THE WORLD VALUE SURVEY
Authors: Maksymuk Andriy , Kuzenko Nataliya
Published: May 2021

This article highlights the impact of values on the country’s welfare. Values that are quite constant over a long period of time form an institutional framework within the country. They can contribute to economic development or even prevent it. The aim of the article is to explore, what is the influence of social values, democracy and trade on welfare levels in different counties. The hypothesis is that the dominance in society of secular-rational values and the values of self-expression, democracy and trade (openness to the world) have a positive effect on the level of welfare of countries. The empirical part of the paper is based on the comparative analysis of relationship between GDP per capita and four values such as tolerance and respect, obedience, trust and freedom of choice for two waves of WVS – 2005-2009 and 2010-2014. Using correlation and regression analysis, the relationships between these indicators were evaluated. These values have a positive impact on welfare in OECD countries, some countries of Latin America, Asia and Africa with middle income per capita. However, there is a negative relationship between obedience and GDP per capita. This value is more important for some African and Asian countries and India. The relationship between GDP per capita and the aggregate value index showed a strong positive correlation for OECD countries. Then the regression model was estimated to assess the impact of values, trade and level of democracy on welfare growth and development. The results of the regression analysis showed a significant effect of the aggregated value indicator for all six samples, but this effect is weaker for high-income countries. The effect of the level of democracy is significant and positive only for the sub-sample of democratic countries, while it is negative for high-income countries. The effect of the level of trade on GDP per capita is statistically significant for the sample of all countries, the sub-sample of non-democratic countries and the sub-sample of high income and upper-middle income countries. Thus, we conclude that the institutional factors (the values and the level of democracy) are important determinants of GDP per capita for democratic countries while for non-democratic countries trade is more important.

Authors: Benko Nadiia
Published: May 2021

The subject of the study is the conceptual, theoretical, methodological and applied provisions of state regulation of development and reproduction of human capital for the national economic system management. Methodology. General scientific methods were used in the research process. The method of comparison was used for generalizing the approaches of different researchers on the main dominants of development and reproduction of human capital. Analysis was used to determine the quantitative and qualitative parameters of the dominants of human capital. Syn-thesis was used to determine the methodological principles of labour market regula-tion and human capital development. Induction and deduction were used for deter-mining approaches to the main dominants of human capital. The aim of the article is to generalize various approaches to the main dominants of development and reproduction of human capital on different bases and purposes, to develop a modern theoretical basis for the development of human capital in the country’s economy. The results of the study have shown that to ensure the effectiveness of state regulation of the development and reproduction of human capital, it is necessary to create an appropriate social environment and conditions that promote the fullest use of knowledge and intellectual, creative potential of individuals. Conclusion. The composition of the bases and goals of the dominants of development and reproduction of human capital in Ukraine, in contrast to the existing one, should include labour market regulation policy, national model of combating unemployment, working capacity, cost of human capital and human development index. This will ensure investment, development and human capital management in Ukraine. Analysis of the methodological principles of labor market regulation and human capital development of the European Union and Ukraine, and problems of human capital development in Ukraine allowed us to conclude that they differ significantly. Their difference is explained by different levels of economic and social situation of countries and other factors, in particular the low speed of dissemination and implementation of progressive results of investment in education and science. The practical significance lies in increasing the scientific substantiation of theoretical provisions and practical measures to ensure the mechanism of state regulation of development and reproduction of human capital is in accordance with transformational changes in social relations and market conditions, processes of globalization.

Comparison estimating of classification error rate in decision tree: Data mining
Authors: Yousef M. T. El Gimati
Published: May 2021

Decision Tree (DT) typically splitting criteria using one variable at a time. In this way, the final decision partition has boundaries that are parallel to axes. An observation is misclassified when it falls in a region which does not have the same class membership. Misclassification rate in classification tree is defined as the proportion of observations classified to the wrong class while in the regression tree is defined as a mean squared error. In this paper, we present two of the important methods for estimating the misclassification (error) rate in decision trees, as we know that all classification procedures, including decision trees, can produce errors. Constructed DT model by using a training dataset and tested it based on an independent test dataset. There are several procedures for estimating the error rate of decision tree-structured classifiers, as K-fold cross-validation and bootstrap estimates. This comparison aimed to characterize the performance of the two methods in terms of test error rates based on real datasets. The results indicate that 10-fold cross-validation and bootstrap yield a tree fairly close to the best available measured by tree size.

Kariya kernel is very rich in essential fats, oils and other valuable nutrients which may find applications in many food formulations. To harness these nutrients, processing equipment and machines are to be used. In order to effectively design these machines, the values of some physical properties of kariya nut and kernel are needed. In this study, some physical properties of the kariya nut and kernel were investigated. Results showed that mean major diameter, intermediate diameter, minor diameter and unit mass obtained at the nut moisture content of 19.83 ± 3.71 (w.b.) were 14.16 ± 0.79 mm, 10.17 ± 0.36 mm, 9.78 ± 0.28 mm and 0.503 ± 0.05g, respectively while the corresponding values obtained at the kernel moisture content of 8.89 ± 2.22% (w.b.) were 9.07 ±0.72 mm, 7.32 ±0.49 mm, 7.08 ± 0.41 mm and 0.328 ± 0.03 g, respectively. The values of calculated geometric mean diameter were 11.20 ±mm and 7.77 ± 0.36 mm, for the kariya nut and kernel, respectively. The skewness value of the sample distribution of 0.08 and -0.24 were recorded for the kariya nut and kernel, respectively. The sphericity, surface area, volume, density, bulk density and porosity were 79.27 ± 3.07%, 394.75 23.13 mm2, 738.37 ± 64.96 mm3 , 681.1 ± 20 kg/m3, 440.24 ± 0.04 kg/m3 and 36.65 ± 0.74% ; and 85.97 ± 5.27%, 189.85 ± 17.34 mm2, 246.71 ± 33.60 mm3, 1342.1 ± 136.23 kg/m3, 773.06 ± 0.06 kg/m3 and 42.28 ± 4.10% for the kariya nut and kernel respectively.

Authors: Taner Bozkurt  , Zeynep Ergun
Published: May 2021

Pomegranate (Punica granatum) is a perennial herb with its long history and has been the symbol of health, fertility and spirituality. In addition to being consumed as fresh fruit, pomegranate is consumed as pomegranate juice, syrup, pomegranate syrup and many different product groups. In particular, pomegranate seeds, which are often produced as waste, are evaluated separately in terms of their fatty acid composition and antioxidant capacity. In this study, the fatty acid composition of pomegranate seed oils was determined by gas chromatography/mass spectrophotometry (GC/MS). Total antioxidant activity analysis was performed using DPPH (2, 2-diphenyl-1-picrylhydrazyl) method and antioxidant activity value was determined as trolox equivalent (TE). In the study, it was determined that the antioxidant capacity was 171.44 mg TE / 100g. According to GC / MS analysis, it was determined that the most dominant fatty acid was punicic Acid (68.12%). Oleic acid (8.51%), linoleic acid (6.71%) and palmitic acid (5.55%) are the highest fatty acids after punicic acid. It is clear that apart from the widespread consumption of pomegranate fruit, which is very beneficial for health, its seeds can also be used.

Permeability estimation is crucial for formation evaluation, but faces challenges when used in low-permeability, unconventional formations. NMR well logging is often used to estimate formation permeability, but in many unconventional formations, the current NMR methods are not adequate. We have developed a new method to estimate permeability using a modified Carman-Kozeny model with pore size, tortuosity, and porosity information inferred from NMR restricted diffusion measurements. In this study, we focus on two low-permeability, organic-rich chalks (0.017 and 0.035 md) with connate water present. They are from the same formation but have different depths, TOC (total organic carbon), and bitumen content. These differences affect pore size, tortuosity, and permeability. The core samples are pressure saturated with two hydrocarbons—high-pressure methane or decane—with connate water present. NMR measurements are conducted under pressure to obtain the restricted diffusivity of the hydrocarbon-bearing pore space. In planning the NMR restricted diffusivity measurements, an optimum series of diffusion-encoding times are chosen for the unipolar stimulated-echo pulse sequence to obtain the correlation between the restricted diffusivity (D) and free diffusion length (LD). By applying the Padé fit to the restricted diffusivity, we can better estimate the diffusive tortuosity (τ) and pore-body size (d) of the hydrocarbon-filled pore space. The estimated pore-body size, tortuosity, and porosity from NMR are then used to predict permeability. We introduce a modified Carman-Kozeny model, which shows advantages over older methods like SDR and Timur-Coates models. The advantages of the new method are shown in organic-rich chalk with complex pore structures and organic matter. This new method can potentially be used for estimating permeability by well-logging and core-log integration.
Machine-Learning-Enabled Automatic Sonic Shear Processing
Authors:   Schlumberger Doll-Research Center, Liang Lin , Lei Ting ,   Schlumberger Doll-Research Center
Published: May 2021

Flexural-dipole sonic logging has been widely used as the primary method to measure formation shear slowness because it can be applied in both fast and slow formations and can resolve azimuthal anisotropy. The flexural-dipole waveforms are dispersive borehole-guided waves that are sensitive to borehole geometry, mud, and formation properties, and therefore the processing techniques need to honor the physical dispersive signatures to obtain an accurate estimation of shear slowness. Traditional processing techniques are based on either a model-dependent method, in which an isotropic model is used as a reference to compensate for the dispersion effect, or a model-independent method, which optimizes nonphysical parameters to fit a simplified model to the field dispersion data extracted in the slowness-frequency domain. Many methods often require inputs, such as mud slowness, frequency bandpass filter, or an initial guess of formation shear. Consequently, these methods often fail to interpret the dispersion signature properly when those inputs are inaccurate or when the waveform quality is poor due to downhole logging noises. The users must manually tune the processing parameters and/or choose different methods as a workaround, which causes extra time and effort to obtain the result, hence imposes a significant challenge for automating sonic shear processing. We developed a physics-driven, machine-learning-based method for enhancing the interpretation of borehole sonic dipole data for wireline logging in an openhole scenario. A synthetic database is generated from an anisotropic root-finding, mode-search routine and used to train a neural network model as an accurate and efficient proxy. This neural network model can be used for real-time sensitivity analysis and performing inversion to the measured sonic dipole dispersion data to estimate relevant model parameters with associated uncertainties. We introduce how this trained model can be used to enhance the labeling and extraction of the dipole dispersion mode. We developed a new method that outperforms previous model-dependent and model-independent approaches because the new method introduces a mechanism to constrain the solution with physics that also has the capability to incorporate more complicated physical dispersion signatures. This new method does not rely on a good initial guess on mud slowness and formation shear slowness, nor any tuning parameter. This leads to significant progress toward fully automated sonic interpretation. The algorithm has been tested on field data for challenging borehole and geological conditions.

A unique challenge for ongoing Schrader Bluff development is to increase field production with the drilling of a high-angle, multilateral producer. To address the challenge, a project was initiated with the primary goal to safely drill five laterals with a key emphasis on maximizing net sand exposure while balancing the short- and long-term value associated with selecting the appropriate technology. This paper focuses on the technical aspects of the proactive geosteering with azimuthal resistivity measurements and multilayered user-guided inversion used in this project. The prewell study based on multiple offset wells is discussed in detail, followed by presenting the highlights of the real-time drilling/geosteering operations, and concluded with the comprehensive post-well analysis study after all five laterals were drilled. The key effort before the drilling was thorough simulation of various scenarios for several target formations. It allowed the selection of the proper geosteering service level (tools and data inversion methods), providing required resolution capabilities but not exceeding the project budget. Value of inversion on real-time data is demonstrated with several examples accompanied by uncertainty analysis of inversion results. Post-well processing included quantification of the main fault amplitude, in-depth uncertainty analysis, and 3D visualization, as well as geological interpretation using an advanced 3D modeling application. The final position and orientation of the major fault were supported with the results of 2D inversion performed in the vicinity of the fault. The integration between advanced geosteering tools and an active team effort helped achieve this complex penta-lateral well, drilling all legs with excellent directional control with numerous steering adjustments and a final net pay of 20,455 ft out of 28,886 ft drilled, which exceeded the operator’s expectations.

The reduction of energy consumption of cars is always a significant issue in automotive design. Turbulent flow around a car body is very difficult to simulate accurately due to the complexity of the flow conditions around the body, such as complex flow separation and laminar to turbulent flow transition. In particular, flow over the Ahmed body with a rear angle of 25o is considered a challenging problem for the RANS approach with two-equation turbulence models. In this study, we aim to analyze the Kelvin-Helmholtz instability associated with this flow with a URANS approach. Methodology for utilizing the URANS method is fully discussed. The predicted velocity profiles and drag coefficient are com-pared with experimental results. Three turbulence models, such as the k-ε, k-ω and SST models, are assessed and validated with experimental data. The aim of the study is to evaluate the performance of these models for the study of the Kel-vin-Helmholtz instability over the Ahmed body and for car bodies generally us-ing experimental data for their validations. It is found that the URANS approach with the turbulence models with proper numerical treatment can perform as well as or even better than the LES. And the SST model shows the best performance compared with other turbulence models.

The initial study with 5 patients in the pharmacy installation, of Caruban Hospital, concluded that all patients stated that they were tiring and queued for a long time. This study aims to examine whether there is an effect of type of drug, facility, and infrastructure to waiting time to get pharmacy service at Caruban Regional Public Hospital. The Design of this research used quantitative research The sampling technique was purposive sampling with total sample are 100 respondents. The statistical analysis used dummy regression. The average waiting time for pharmacy service is about 60 minutes for concocted drug, Average waiting time for packaged drugs is 46.5 minutes, and mixed drug is 69.5 minutes. 72 respondents stated that the infrastructure was in the good category and the rest said it was moderate.The results of the dummy regression analysis concluded that facilities and infrastructure had a significant effect simultaneously on the waiting time for services. The partial test results showed that the significance value for the facilities and infrastructure variable was 0.000, and for the variable dosage forms in mixed prescriptions it had a significance value of 0.023. The means variable is the variable that most influences the waiting time for the prescription service. The types of drugs in the prescription and waiting room infrastructure have a significant effect simultaneously on the length of queuing for drugs.
