ON ESTIMATES OF COEFFICIENTS OF GENERALIZED ATOMIC WAVELETS EXPANSIONS AND THEIR APPLICATION TO DATA PROCESSING
Authors: Makarichev Victor Olexandrovych , Lukin Vladimir Vasilyevich , Brysina Iryna Victorivna
Published: March 2020

Discrete atomic compression (DAC) of digital images is considered. It is a lossy compression algorithm. The aim of this paper is to obtain a mechanism for control of quality loss. Among a large number of different metrics, which are used to assess loss of quality, the maximum absolute deviation or the MAD-metric is chosen, since it is the most sensitive to any even the most minor changes of processed data. In DAC, the main loss of quality is got in the process of quantizing atomic wavelet coefficients that is the subject matter of this paper. The goal is to investigate the effect of the quantization procedure on atomic wavelet coefficients. We solve the following task: to obtain estimates of these coefficients. In the current research, we use the methods of atomic function theory and digital image processing. Using the properties of the generalized atomic wavelets, we get  estimates of generalized atomic wavelet expansion coefficients. These inequalities provide dependence of quality loss measured by the MAD-metric on the parameters of quantization in the form of upper bounds. They are confirmed by the DAC-processing of the test images. Also, loss of quality measured by root mean square (RMS) and peak signal to noise ratio (PSNR) is computed. Analyzing the results of experiments, which are carried out using the computer program "Discrete Atomic Compression: Research Kit", we obtain the following results: 1) the deviation of the expected value of MAD from its real value in some cases is large; 2) accuracy of the estimates depends on parameters of quantization, as well as depth of atomic wavelet expansion and type of the digital image (full color or grayscale); 3) discrepancies can be reduced by applying a correction coefficient; 4) the ratio of the expected value of MAD to its real value behaves relatively constant and the ratio of the expected value of MAD to RMS and PSNR do not. Conclusions: discrete atomic compression of digital images in combination with the proposed method of quality loss control provide obtaining results of the desired quality and its further development, research and application are promising.
TOMIC FUNCTIONS AND LACUNARY INTERPOLATION SERIES IN BOUNDARY VALUE PROBLEMS FOR PARTIAL DERIVATIVES EQUATIONS AND IMAGE PROCESSING
Authors: Rvachov Volodimir Olexijovych , Rvachova Tatiana Volodimirivna , Tomilova Evgenia Pavlovna
Published: March 2020

In the paper we consider and solve the problem of construction of the so called tomic functions – the systems of infinitely differentiable  functions which while retaining many important properties of the shifts of atomic function up(x) such as locality and representation of algebraic polynomials  and being based on the atomic functions  nevertheless have nonuniform character and therefore  allow to take into account the inhomogeneous and  changing character of the data encountered in real world problems in particular in boundary value problems for partial differential equations with variable coefficients and complex geometry of domains in which these boundary value problems must be solved. The same class of tomic functions can be applied to processing,denoising and sparse storage of signals and images by lacunary interpolation. The lacunary or Birkhoff interpolation of functions in which the function is being restored by the values of derivatives of orderin points in which values of function and derivatives of order k<r are unknown is of great importance in many real world problems such as remote sensing. The lacunary interpolation methods using the tomic functions possesss important advantages over currently widely applied lacunary spline interpolation in view of infinite smoothness of tomic functions.The tomic functions can also be applied to connect (to stitch) atomic expansions with different steps on different intervals preserving smoothness and optimal approximation properties. The equations for of construction oftomic functions tofuj(x) –analogues of the basic functions of the generalized atomic Taylor expansions are obtained – which are needed for lacunary (Birkhoff) interpolation. For the applications in variational and collocation methods for solving bondary value problems for partial derivative and integral equations the tomic functions ftupr,j(x) are obtained that are analogues of B-splines and atomic functions fupn(x). Using similar methods, the tomic functions based on other atomic functions such as Ξn(x) can be obtained.
КОГНІТИВНІ ТА ЕРГОНОМІЧНІ АСПЕКТИ ВЗАЄМОДІЇ ЛЮДИНИ З КОМП’ЮТЕРОМ

The article is devoted to little-studied aspects of human-computer interaction, which determines the behavior of a complex dynamic system in extreme conditions. The viability of its elements, including humans, is influenced by a variety of environmental stress factors and activities. Their combination can lead to unpredictable technical failures and psychophysiological breakdowns, as well as to systemic management problems. The main goal of this work is to justify the need to actualize the study of the extreme principles of physics and their use in the interdisciplinary "Engineering of human factors", as well as in special courses in engineering and technology.An analysis of the methods of system dynamics, synergetics, and cognitive ergonomics indicates that the source of most problems of digitalization of dynamic systems, on the one hand, is an increase in the diversity in the methods of processing information flows, types of visualization and methods of their analysis, and on the other, the variability of psychophysiological capabilities restrictions and cognitive perception by a human operator, (designer, etc.) the variety of information on the basis of which system decisions are made. It is proposed to expand interdisciplinary connections related to the extreme principles of dynamics (electrodynamics, thermodynamics, optics, and others), integrative indicators of orderliness, energy balance, and the entropy criteria of dynamic stability. It is proposed to expand the knowledge base by transforming the dynamics of digitizing information flows of various nature into structural patterns of the cognitive space of probable events. Its use in the engineering of human factors allows a) to develop an intellectual learning support system; b) apply an interdisciplinary convergent methodology in training. All this will contribute to a more effective interaction between the student and the computer and the development of his critical thinking and intuition, and will increase the ergonomic quality of dynamic systems even at the design stage. Attention is drawn to the influence of the psychophysiological state of a person on the cognitive perception of information flows of various nature, as well as on cognitive bias in making systemic decisions. Therefore, an interdisciplinary view of the possibilities and limitations of human-computer (machine) interaction under the influence of stress factors of the environment and activity is very important at all stages of the graduate design of computer systems.
Report of agonistic interaction in Malagasy frogs of the genus Gephyromantis (Anura, Mantellidae)
Authors: Lam Bernardo , Noël Jean , Crottini Angelica , Andreone Franco , Rosa G. M.
Published: March 2020

Territorial behaviour has been recorded in several amphibian families but rarely in frogs from Madagascar, despite the extremely high species diversity in the country. Here we describe the agonistic encounter of two male frogs of the Malagasy-endemic genus Gephyromantis. The physical combat was preceded by a switch from the advertisement call to a more aggressive tone of the resident male upon the intruder approaching. Although no physical interaction has been reported before, the change in call type is similar to that observed in other Gephyromantis. The combat lasted for about one minute with both males trying to subdue each other, until the intruder retreated.
CANADA’S PROSTHETIC COVERAGE: A REVIEW OF PROVINCIAL PROSTHETIC POLICY
Authors: Howard Calvin , Saraswat Dave K. , McLeod Graham , Yeung Albert , Jeong Danielle , Lam Jack
Published: March 2020

The Canadian healthcare system serves as an example of equity and federal service to citizens across the world. However, it is not without its challenges. Prosthetic coverage across Canada is highly variable and largely unable to provide equal coverage for Canadian persons living with amputation. Many persons with limb loss are forced to rely upon personal resources, fundraising, or the charity of non-governmental organizations in order to meet this basic healthcare need. This disparity in the Canadian healthcare system is unusual and largely undescribed in the literature. We thus explore the nature of Canadian healthcare prosthetic coverage across Canada, investigating the variability in coverage, presence of prosthetic coverage policies, clarity of policy, eligibility criteria, and interval of prosthetic replacement. Our findings highlight potential areas for improvement within current Canadian healthcare policy.

Estimation idea by proportion of samples in election polls: a classroom experience

Abstract: This experience report addresses questions about the use of manipulable concrete material that constitutes a rich possibility as a didactic resource, as well optimizing learning when associated with statistics study. Assuming that when learning, occurs with dynamics and attractive ways, becomes effective and meaningful, it is intended to highlight, through an experience of exploring the resources of a statistic ballot box, how the act of teaching requires from the teacher creative attitudes, including the use of varied resources which promotes greater approximation of the contents studied with the reality of students. We will discuss some intuitive ideas that substantiate the Statistical Theory of Estimation by Proportion when it comes to voting intention research and analyze the effect of the manipulable resource associated with statistical content, realizing this resource as an ally to achieve the objectives that enable the teaching and learning process, as well as to demystify misconceptions about statistical methods employed in electoral polls.

A vertente comportamental da educação financeira
Authors: Campos Celso Ribeiro , Coutinho Cileda De Queiroz e Silva , Figueiredo Auriluci Carvalho de
Published: March 2020

Resumo: A Estratégia Nacional de Educação Financeira foi implantada em 2010, mas não resultou em melhora da situação financeira das famílias. Ao contrário, o consumo das famílias tem aumentado mais do que a renda, provocando mais endividamento e inadimplência (CAMPOS; HESS; SENA, 2018). Em nossas pesquisas sobre educação financeira, temos identificado duas vertentes, instrumental e crítica. A vertente instrumental trata o indivíduo como consumidor de produtos financeiros, enquanto a vertente crítica tem um viés social e humanístico. Apesar de termos defendido a vertente crítica, os resultados não parecem ser suficientes. Com isso, buscamos explorar outra vertente, a comportamental. Neste artigo, apresentamos conceitos básicos de economia e fazemos uma resenha de duas obras de Zygmunt Bauman, para depois explorarmos os conceitos de economia comportamental. Nosso objetivo é trazer essa vertente para o universo da educação financeira, contribuindo para que se possa entender melhor como trabalhar esse tema no âmbito da sala de aula.

The behavioral stream of financial education

Abstract: National Strategy for Financial Education was implemented in 2010 but did not result in any improvement in the families' financial situation. On the contrary, household consumption has increased more than income, leading to more indebtedness and defaults (CAMPOS; HESS; SENA, 2018). In our research on financial education we have identified two streams, instrumental and critical. The instrumental stream treats the individual as consumer of financial products, while the critical has a social and humanistic bias. Although we have defended the critical stream, the results do not seem enough. Thus, we seek to explore another stream, the behavioral. In this article, we present basic economics concepts and review two of Zygmunt Bauman's works, and then explore the concepts of behavioral economics. Our goal is to bring this aspect to the financial education universe, helping to better understand how to work on this theme within the classroom.

Use of electronic schedules for statistical learning

Abstract: This paper intends to report the experience of a mini-course in which Statistics contents are treated with the help of electronic spreadsheets, focusing on the demystification of basic statistics and adapting this content for decision making. The use of the spreadsheets for the calculation of the estimates made it possible to offer to students of intermediate level topics of statistics with a depth that is only approached at graduation level. Participation in the mini-course was considered satisfactory by those involved, who thought they had learned the contents and were able to apply them on a daily basis and to be able to develop scientific initiation projects. Due to the results, it is possible to propose an extension project not oinly to test the methodology for School and High School as well as for the qualification of teachers of Basic Education.

Pedagogical activities in promoting active learning of graduate students in statistical disciplines

Abstract: This experience report presents three activities designed to arouse the interest of higher education students in statistics and to promote their active learning in the classroom. In its planning and development, we considered the assumptions of the Theory of Knowledge Biology and Cognitive Neuroscience, so that students perceive themselves as knowledge producers and co-responsible for their learning process. In different ways, the three activities enabled the active participation of students, who lost their fear of the discipline and participated in debates and discussions enhanced by the teaching methodology adopted. It is concluded that rethinking pedagogical practice can lead the teacher to find ways to help students overcome their difficulties in understanding statistical concepts.

Prospecção ontológica como instrumento para a qualificação do sentimento de realidade em estudantes do ensino médio
Authors: Custódio José Francisco , Bosquetti Guilherme Henrique Scotti , Teixeira Reginaldo Manoel
Published: March 2020

Resumo: Na intenção de compreender “o que é real” para estudantes, alguns pesquisadores introduziram na educação científica a noção de sentimento de realidade. Neste trabalho, partimos de uma conceitualização de sentimento de realidade baseada na Teoria dos Três Mundos de Popper, da qual derivamos um instrumento teórico-metodológico denominado prospecção ontológica. Assim, investigaremos o potencial da prospecção ontológica para qualificar o sentimento de realidade em estudantes do Ensino Médio. Por intermédio da técnica de entrevista-sobre-cenários abordamos 10 estudantes a respeito do sentimento de realidade sobre os objetos caneta, árvore e energia. As entrevistas foram categorizadas em termos de interações sensoriais (ISEN), cognitivas (ICOG), sociais (ISOC) e afetivas (IAFE), que são responsáveis pela emergência e intensificação do sentimento de realidade. Os resultados mostraram que as ISEN e ISOC foram as mais destacadas nas explicações criadas pelos estudantes. Concluímos que a prospecção ontológica é um instrumento fértil para qualificar o sentimento de realidade.Palavras-chave: Categoria ontológica; Dimensão ontológica do conhecimento; Entrevista-sobre-cenários; filosofia da Ciência; Os três mundos de Popper. Ontological prospection as an instrument for qualifying the feeling of reality in high school studentsAbstract: In order to understand "what is real" for students, some researchers have introduced into science education the notion of a sense of reality. In this work, we start from a conceptualization of feeling of reality based on the Theory of the Three Worlds of Popper, from which we derive a theoretical-methodological instrument called ontological prospecting. Thus, we will investigate the potential of ontological prospecting to qualify the sense of reality in high school students. Through the technique of interview-about-scenarios we approached 10 students regarding the feeling of reality on the objects pen, tree and energy. The interviews were categorized in terms of sensory (ISEN), cognitive (ICOG), social (ISOC) and affective (IAFE) interactions, which are responsible for the emergence and intensification of the feeling of reality. The results showed that the ISEN and ISOC were the most prominent in the explanations created by the students. We conclude that the ontological propspection is a fertile instrument to qualify the feeling of reality.Keywords: Ontological category; Ontological dimension of knowledge; Interview-about-scenarios; Philosophy of science; Popper's three worlds

Furthermore, even though there is centrality in the utilization of texts, we identified a wide diversification in the utilized didactic resources and topics of Physics covered in the proposals.Keywords: History and Philosophy of Science; Pedagogical intervention; Didactic resources; Basic Education.
How does a fraction get its name?
Authors: Powell Arthur B.
Published: March 2020

Abstract: Philosophical and cultural perspectives shape how a fraction is named and defined. In turn, these perspectives have consequences for learners' conceptualization of fractions. We examine historical foundations of two perspectives of what are fractions—partitioning and measuring—and how these views influence fraction knowledge. For the dominant perspective, partitioning, we indicate how its approach to what is a fraction that discretizes objects and its well-meaning visual correlates cause learners a host of perceptual difficulties. Based on the human cultural and social practice of measuring continuous quantities, we then offer an alternative understanding of what is a fraction and illustrate the promise of this view for fraction knowledge. We introduce pedagogical tools, Cuisenaire rods, and illustrate how they can be used to implement a measuring perspective to comprehending properties and a definition of fractions. We end by sketching how to initiate a measuring perspective in a mathematics classroom.Keywors: Fractions; Gattegno; Measuring; Partitioning; Unit fractions. Como uma fração recebe seu nome?Resumo: Perspectivas filosóficas e culturais moldam como uma fração é nomeada e definida. Por sua vez, essas perspectivas têm consequências para a conceitualização de frações dos estudantes. Examinamos os fundamentos históricos de duas perspectivas do que são frações—particionamento e medição—e como essas visões influenciam o conhecimento das frações. Para a perspectiva dominante, partição, indicamos como sua abordagem ao que é uma fração que discretiza objetos e seu correlato visual bem-intencionado causa aos alunos uma série de dificuldades perceptivas. Com base na prática cultural e social humana de medir quantidades contínuas, oferecemos um entendimento alternativo do que é uma fração e ilustramos a promessa dessa visão para o conhecimento da fração. Introduzimos ferramentas pedagógicas, varas Cuisenaire e ilustramos como elas podem ser usadas para implementar uma perspectiva de medição para compreender propriedades e uma definição de frações. Terminamos esboçando como iniciar uma perspectiva de medição em uma sala de aula de matemática.Palavras-chave: Frações; Gattegno; Medição; Partição; Frações unitárias.

Menurut KBBI (Kamus Besar Bahasa Indonesia) Sejarah adalah suatu kejadian atau peristiwa yang telah lampau dan benar-benar terjadi. Namun kerap kali untuk mempelajarinya, terlalu membosankan dan membuat jenuh karena banyak menghafal. Karena itulah dibuatnya aplikasi game Gerbang(Gerakan Bangsa). Game ini bertemakan tentang sejarah penjajahan di Indonesia. Dengan menggunakan metode IMSDD (Interactive Multimedia System of Design and Development) dan aplikasi Unity, game Gerbang diciptakan dengan OS Android agar mudah digunakan dan menarik minat pengguna. Di dalam metode pengembangan IMSDD, terdapat 4 tahapan, yaitu: 1. System Requirement, 2. Design Concideration, 3. Implementation, 4. Evaluation.  Dimana masing-masing tahapan pada akhirnya membentuk game Gerbang yang memiliki 6 tema soal berbeda yang terdiri dari Jepang, Inggirs, Prancis, Belanda, Spanyol dan Portugis. Nama-nama tersebut merupakan nama negara yang pernah menjajah Indonesia. Dengan 6 tema yang berbeda itu pula, pengguna dapat mengetahui sebatas mana pengetahuan mereka prihal penjajah ketika menempati Indonesia di masa lampau
