A Cybernetic Participatory Approach for Whole-Systems Modelling and Analysis, with Application to Inclusive Economies
Authors: Hassannezhad Mohammad , Gogarty Mary , O’Connor Clementine Hill , Cox Julian , Meier Petra S. , Purshouse Robin C.
Published: January 2021

Traditional participatory systems modelling demands
synchronous time from many experts and face-to-face interaction. This is not
always feasible (e.g. recent pandemic) and can restrict which participants can
be included. There are additional limitations in the effectiveness of physical
paper-based modelling when handling large complex systems with numerous
variables and links between them. The key challenge facing practitioners is
then how we can retain the benefits of traditional participatory modelling whilst
exploiting the advantages of new technologies? This paper contributes to
development of an original systematic methodology based on Cybernetic
principles. The proposed method, refers to 5X – standing for Expose,
Explore, Exploit, Explain, and Expand, offers a
fully virtual co-produced environment for better engagement of stakeholders,
developing more confidence in systems mapping, and promote knowledge to other
policy areas. A primary application of the proposed method in a real policy
setting illustrates its capability in generating a shared policy understanding
of complex Inclusive Economy system, where
there is conflicting or dispersed knowledge about system structure, refining this
understanding through online feedback channels, and transferring this
understanding to wider policy and academic partners through mutual
relationships.
Simultaneous Representation and Separation for Multiple Interference Allied with Approximation Message Passing
Authors: Wang Guisheng
Published: January 2021

Broadband reliable communication is a competitive 5G technology for cognitive communication scenarios, but meanwhile introduces multiform interference to existing broadband transform domain communication system (TDCS) transmission. In order to facilitate the improvement of the anti-jamming performance for the coexistence of diverse interference and TDCS signals in wireless heterogeneous networks, it is important to separated and eliminate various interference to TDCS systems. In this paper, a novel sparse learning method-based cognitive transformation framework of interference separation is formulated for accurate interference recovery, which can be efficiently solved by iteratively learning the prior sparse probability distribution of the interference support. To further improve the separation accuracy and iterative convergence, the principal component analysis and Bayesian perspective in orthogonal base learning are exploited to singly recover the multiple interference and TDCS signals. Moreover, utilizing different sparsity states of spectrum analysis, the proposed novel interference separation algorithm is extended to simultaneous separation based on state evolving of approximation message passing, which iteratively learns the belief propagation posteriors and keeps shrunk by iterative shrinkage threshold. Simulation results demonstrate that the proposed methods are effective in separating and recovering the sparse diversities of interference to TDCS systems, and significantly outperform the state-of-the-art methods.

Research Using Metal Detectors at the Battlefield of Muhi : Community Archaeology, Battlefield Investigation and Related Methodological Issues
Authors: Laszlovszky József , Rácz Tibor Ákos
Published: January 2021

The defeat of the Hungarian forces at the battle of Muhi was a key historical episode, since it opened the country to the Mongol invasion. This event had complex consequences that have not yet been fully clarified regarding the further development of Hungarian society and its economy. The identification of the site of the battlefield has contributed to the better understanding of the events of 11 April 1241. The known course of events has been established through subjective written sources that were often based on indirect information. The identification of certain elements of the battle can provide new information, since it may be possible to reconstruct the tactical options provided to the leadership of the Hungarian and Mongolian forces by the geographical circumstances and how the location influenced the outcome of the battle. The research on the battlefield of Muhi gained momentum through the assistance of volunteers associated with a number of museums using metal detectors. In this article, we investigate the following question: what kind of opportunities does community archaeology provide in the interdisciplinary investigation of an Árpád Period (1000–1301) battlefield, and what kind of practical and methodological problems face research using metal detectors?
Intentos de establecer relaciones diplomáticas entre Colombia y Marruecos en los años 1825 -1827
Authors: Dziubiński Andrzej
Published: January 2021

Morocco has a long history of relations with the American states. Diplomatic relations with independent governments were preceded by a number of trade links. After the first wave of revolutions against Spanish colonial dependency the freshly formed states of South America participated in interesting events, which relate with their occasional maritime presence in the ports of Morocco. This had started with the 1821 arrival of the Venezuelan ship "Nuevo Congreso" in Tangier.Dziubiński gives accounts of different occasions on which Columbian ships visited Moroccan ports. Their presence included attempts to establish diplomatic relations with the Moroccan government. Dziubiński judges this presence as diversion aimed at Morocco's neighbor and former Columbian sovereign, the Kingdom of Spain.

Resistance to Penetration (RP) can be found on various soil conditions and even on different agricultural production systems. The present work aimed to diagnose compacted layers along the soil profile. For the development of the work, it was necessary to use a specific equipment for data collection of RP whose name and Digital Penetrometer (Falker). Able to measure compacted layers every 5 cm depth up to a distance of 60 cm. along the soil profile in addition, it is able to provide data via graphs through a computer system. Random collections were carried out on different farms in the Araguaia Xingu region, so the criterion used to develop the work was to collect 15 points per plots at a maximum depth of 40cm and the same should be found in its third year of soybean cultivation. Corn (Safrinha). A total of 135 points were collected along 9 farms in the region, and after analyzing the points through the PenetroLOG Software. An average of the 15 points of each farm was carried out, as well as the final average of all the farms to reinforce the individual means. It was concluded that, in the soybean and maize out-season system, the compacted layer is between 14 and 20 cm deep along the soil profile with mean values of pressure of 1975 and 2504 kpa. This suggests alteration of the management used in the soils of the evaluated areas.

Authors: Silva Patricia
Published: January 2021

Este trabalho é fruto de uma intervenção numa turma de Sociologia do Ensino Médio, que deu continuidade ao tema “Tecnologia, Trabalho e Mudanças Sociais” através da discussão da precarização, flexibilidade, terceirização e principais mudanças atuais na dinâmica do trabalho atreladas ao contexto neoliberal (ANDERSON, 1995; BRAGA, 2012; FILGUEIRAS, 2006; HARVEY, 1989), relacionadas às atuais mudanças na Consolidação das Leis do Trabalho (CLT), tomando como exemplo férias, jornada, tempo na empresa, remuneração, trabalho intermitente, gravidez e terceirização. Para estimular os alunos ao contato com o trabalho, solicitou-se que realizassem entrevistas com trabalhadores/as, para investigarem o impacto dessas mudanças na dinâmica de trabalho desses/as. Essa estratégia objetivou a compreensão da entrevista como técnica de pesquisa e produção de conhecimento, o que sequenciou no desenvolvimento da criticidade, com base na perspectiva de que, segundo Demo (1996), o ensino deve ser efetivado pelo estímulo à pesquisa, em que professor/a e discente entendam e pratiquem a pesquisa em seu cotidiano educacional. Os/as alunos/as relacionaram os resultados da entrevista com o conteúdo estudado, pela produção de escritos sobre os aprendizados, os quais foram colados num papel maior e lidos na sala, com reflexões após a leitura de cada um. Essa intervenção, ao permitir o contato dos/as alunos/as com trabalhadores através da entrevista, bem como a discussão dos resultados, possibilitou que esses/as atribuíssem maior significado à Sociologia em seus estudos.

Published: January 2021

No presente artigo objetivamos identificar os atos de Insubordinação Criativa revelados nas experiências de aprendizagem e de ensino de Estatística narradas pela primeira autora. Entendemos que a formação de professores se configura em um processo contínuo que se estende por toda a vida a partir das experiências vividas como estudantes na Educação Básica e Superior, bem como sujeitos do seu cotidiano em ambientes externos na escola e na futura atuação docente. Assim, realizamos uma Análise Narrativa da escrita narrativa autobiográfica da primeira autora, na qual conta suas experiências ao longo da formação docente. Para subsidiar as discussões, fundamentamos nossas explicações com base na teoria e epistemologia da Biologia do Conhecer, proposta por Maturana e Varela (2005). Como resultados identificamos cinco atos de Insubordinação Criativa, assim denominados: 1) Deixar que algo lhe passe; 2) Colocar-se na reflexividade; 3) Autoformar-se e transformar-se; 4) Assumir risco em (re)significar a experiência; 5) Deixar vestígios e provocar efeitos. Estes atos referem-se às atitudes insubordinadas, nas quais a primeira autora atuou de forma criativa na experiência. Consideramos que este trabalho possa contribuir para que outros professores reflitam suas experiências no ensinar e no aprender, de modo a realizarem atitudes de Insubordinação Criativa nos seus contextos.

Utopias e ensino de Matemática: uma história
Authors: Brito Arlete Jesus , Oliveira Adriel Gonçalves
Published: January 2021

A discussão sobre os potenciais da Literatura para a História não é recente. A ampliação de tipos de fontes que podem se configurar em documentos históricos e a problematização sobre a existência de textos “verdadeiros”, “sem intenções ideológicas” que supostamente indicariam, de maneira transparente, o que teria ocorrido no passado, favoreceu a percepção, por parte dos historiadores, sobre a fecundidade de textos literários para a escrita de interpretações históricas. Segundo Ginzburg (2007), tais textos trazem rastros e fornecem indícios do passado tanto quanto qualquer outro. Diversos trabalhos em História da Educação Matemática também têm recorrido à Literatura (BRITO, 2011; BRITO, RIBEIRO, 2013; MONTOITO, 2013; OLIVEIRA, 2015). Assim, no artigo aqui proposto, abordaremos, entre outros documentos, utopias elaboradas entre fins de século XVI e início do XVII, com o intuito de analisar as propostas de ensino de matemática que emergiram no começo da Idade Moderna. Temos por pressuposto que tais propostas colaboraram para configurar discursos sobre matemática e sobre seu ensino ainda manifestos na atualidade. A escrita desse artigo utiliza alguns elementos literários.
Matemática e literatura infantil: um livro, um jogo e o desafio de “desenhar” o tempo
Authors: Arnold Denise Soares , Dalcin Andréia
Published: January 2021

O presente artigo apresenta o recorte de uma pesquisa qualitativa de mestrado profissional, na perspectiva da pesquisa-ação, que investigou conexões entre matemática e literatura infantil. As atividades propostas a partir do livro Contagem Regressiva foram realizadas em uma turma de Educação Infantil de escola pública gaúcha. A exploração do livro e a contagem por ele sugerida levaram a um jogo, que provocou os alunos à observação de um relógio de ponteiros. Os registros destas crianças, de cinco e seis anos, evidenciam suas hipóteses sobre a passagem do tempo e noções de continuidade, nos alertando para o potencial pedagógico do relógio analógico na construção do conceito de tempo e na compreensão dos instrumentos que o medem. Além disso, o estudo reforça a importância da narrativa e da ludicidade no desenvolvimento das crianças pequenas. O trabalho com livros de leitura infantil potencializa a exploração de conceitos matemáticos complexos de modo intuitivo.

Der zunehmende Einsatz von Industrierobotern in der Zerspanung setzt eine deutliche Erhöhung der Bearbeitungsgenauigkeit voraus. Dies bedingt aufgrund der Steifigkeitseigenschaften von Robotern eine Optimierung der Bearbeitungsstrategien und Zerspanparameter. Der Beitrag beschreibt die experimentelle Untersuchung des radialen Arbeitseingriffs bei der Kunststoffzerspanung, um über die Wahl geeigneter Eingriffsgrößen das Schwingungs- und Abdrängungsverhalten des Roboters und damit die Bearbeitungsqualität zu verbessern.

 

The prerequisite for an extended use of industrial robots in machining is a significant increase in machining accuracy. This requires an optimization of machining strategies and cutting parameters due to the stiffness of the robot.

Für kleine und mittelständische Unternehmen (KMU) ist die Fabrikplanung mit digitalen Werkzeugen und Methoden in der Regel nicht wirtschaftlich, obwohl sie die gleichen Qualitätsanforderungen an die Fabrikplanung stellen wie große Unternehmen. Dieser Beitrag zeigt, wie auf Basis von Unternehmensmodellen die technologieintegrierte Fabrikplanung wirtschaftlich die Planungsqualität steigert, indem sie bereits in der frühen Entwicklungsphase Kernelemente der Planung synchronisiert: Fabrikkonzept, Fertigungsprozesse, Technologien und Digitalisierung.

 

For SMEs, factory planning with digital tools and methods is usually not economical, although they have the same quality requirements for factory planning as large companies. This article shows how technology-integrated factory planning economically increases planning quality, based on enterprise models by synchronizing core planning elements in the early development phase: factory concept, manufacturing processes, technologies, and digitization.

In der industriellen Praxis wird eine Vielzahl von Prozess- und Qualitätskontrollaufgaben visuell von Mitarbeitern oder mithilfe von Kamerasystemen durchgeführt. Durch den Einsatz Künstlicher Intelligenz (KI) lässt sich die Programmierung und damit die Implementierung von Kamerasystemen effizienter gestalten. Im Bereich der Bildanalyse können dabei vortrainierte Künstliche Neuronale Netze verwendet werden. Das Anwenden dieser Netze auf neue Aufgaben wird dabei Transfer Learning genannt.

 

In industrial practice, a large number of process and quality control tasks are performed visually by employees or with the aid of camera systems. By using artificial intelligence, the programming effort and thus the implementation of camera systems can be made more efficient. Pre-trained ^neural networks can be used for image analysis. The application of these networks to new tasks is called transfer learning.
