Authors: Zainal Zainal , Febriani Afifah , Oktavia Gifa , Zahara Afrila
Published: February 2024

Juvenile delinquency can be said to be a problem that never ends, as the years go by, the forms and levels of delinquency become more numerous. This is of course still an interesting issue to discuss. In connection with this, this research aims to discuss the forms of efforts made by parents in dealing with juvenile delinquency, as a form of realization of cooperation between parents and the school and the community in overcoming this problem. This research uses a qualitative method with a case study approach. Data sources were taken from parents in Indonesia as key informants, and teenagers as supporting informants through in-depth interviews selected using purposive sampling techniques. The results of the analysis show that the forms of efforts made by parents are: Preventive actions, and efforts to prevent the emergence of juvenile delinquency. Parents make efforts to prevent juvenile delinquency from occurring by strengthening their children's faith, such as ordering them to pray and recite the Koran so that their children always remember Allah SWT. However, their teenage children do not carry it out because they are busy or lazy. Repressive measures, and efforts to crack down on violations of social and moral norms can be carried out by imposing punishments. At this repressive stage, parents only give punishments to children when they are at home. Curative and Rehabilitation Actions: These actions are taken after other preventive measures have been implemented and it is deemed necessary to change the offender's behavior by providing more education. Parents do not provide guidance so that their children do not make the same mistakes.

Az elfelejtett hédervári államférfi
Authors: Heka László
Published: February 2024

The life and work of Count Károly Khuen-Héderváry (1849-1918), a Croatian minister and two-time Hungarian Prime Minister, was closely linked to Győr County, especially Hédervár. Born in Silesia, raised in Slavonia, then starting his career in Győr and developing in Zagreb and Budapest, the lawyer, politician and statesman spoke German, Hungarian and Croatian natively. He was connected to all three nations, although he always and without exception declared himself to be of Hungarian nationality. In terms of his political views, he can be said to be a conservative liberal, as he became a parliamentary representative of the Győr Sziget district in the colors of the Liberal Party at the age of 26, but at the same time he remained loyal to the court. After completing two three-year terms (1875-1881), the monarch appointed him the chief lord of Győr County in 1882. A year later, he took the seat of the Ban in Zagreb and ruled Croatia for twenty years. From there, the road led to the Prime Minister’s cabinet, a position he held twice. In this study, we examine Bán’s life path, his activities as a statesman, and the Croatian-Hungarian public law relations.

Published: February 2024

A strategy of angular velocity control of the three-phase permanent magnet synchronous motor is presented in its natural reference frame, i.e., no transformations are made to the mathematical model, so the design of the control algorithm is carried out with the three differential equations obtained for the stator windings as well as with the electromagnetic torque that results with the three stator currents, with the assumption that only the signals of both the stator currents and the angular position are available. To obtain a signal that relates to angular velocity, a state-space representation of a second-order linear filter is used. Likewise, a formal stability analysis of the entire system is presented.
Adjustments for an HVDC link fault detector: practical considerations
Authors:   Universidad Nacional Autónoma de México, Pérez Pinacho Claudia A. , Verde Cristina ,   Universidad Nacional Autónoma de México
Published: February 2024

In this work, practical considerations regarding the use of a fault diagnosis scheme based on a distributed adaptive estimator for the high-voltage direct current (HVDC) transmission line within a simplified model of the DC link are presented. Due to transients and steady-state ripple caused by unmodeled nonlinearities in the HVDC system's conversion part, parameter adjustments of the distributed estimator, including gains and thresholds, are performed to successfully determine the fault magnitude and position within the line through simulation studies. To validate the proposed scheme, numerical simulations of the diagnostic scheme are compared with two HVDC links: a simplified one and the CIGRE (International Council on Large Electric Systems).

Authors:   Universidad Nacional Autónoma de México, Guajardo Benavides Evert , Guajardo Arteaga Marco ,   Universidad Nacional Autónoma de México
Published: February 2024

The control of bilateral teleoperation systems with time-varying delays is a challenging problem that is usually dealt with advanced control techniques. The well-known controllers, such as PD or PID, are scarcely employed and usually in conjunction with other approaches or at least with gravity compensation. In this contribution we intend to show, experimentally, that the standard PID controller exhibits good performance and robustness in position control for teleoperators with variable delays. The results obtained are compared with a well-known algorithm used for teleoperator control.
Model based predictive control (MPC) with constraints applied to a multi-predictor scheme for linear delayed systems with an unstable pole

Published: February 2024

In the present work, a model based predictive control (MPC) strategy using a multi-predictor scheme for unstable high-order linear systems with delay is proposed. The stability analysis of this type of systems is difficult due to two main reasons, the appearance of an infinite number of poles when the feedback of the controller is considered and the second reason, is the delay size considered. In this work the use of a digital multi-predictor scheme is proposed, this device allows to estimate the internal variables of the process, which will be used for the design of the MPC to stabilize the plant. The present proposal considers an MPC with constraints in the control and output variables, which it is one of the most attractive features of this strategy. Numerical simulations are presented to illustrate how the efficiency of the system is increased due to the proposed control approach.

This paper presents the design of a model predictive control (MPC) strategy applied to an optomechatronic system whose objective is to regulate the position of a laser beam system (LBS). The control scheme considers the system model and considers the existence of external disturbances. The feedback control gain is computed by minimizing an objective function of the state and the control prediction horizon. Unlike the reported works for this optomechatronic system, the proposed control scheme considers constraints on the control signal and the system output. The perturbation is estimated by an extended state observer (ESO) and rejected by a pre-compensation term. Numerical simulations validate the strategy design and allow conclusions for future real-time implementation.

This work presents a comparison of two control algorithms for the model of a nonlinear converter system used as a virtual synchronous generator (VSG). The converter connects between the electrical grid and an intermittent renewable system, such as photovoltaic or wind, with backup for sudden disturbances in electricity generation. The proposal of the VSG arises from the fact that, on one hand, the conventional generation system consists of large power plants such as combined-cycle power plants that employ generators and turbines with significant physical inertia. On the other hand, when connecting renewable systems such as wind and solar, which use converters to integrate with the grid, they lack physical inertia. It is necessary to couple this inertia to the system in order to compensate for the disturbances of intermittent systems and thereby maintain the frequency of the electrical power network. It should be clarified that physical inertia is not available when renewable systems such as wind or photovoltaic are connected. Recent studies have shown that it is possible to compensate for the disturbance caused by this lack of inertia through a backup system and the virtual synchronous generator (power converter) using control algorithms. In this work, linearization and super twisting algorithms are employed for handling disturbances, and the main differences between the algorithms are demonstrated when facing sudden changes in active or reactive power.

This work presents a continuous robust control method for stabilizing the reaction wheel pendulum, despite the effect of external perturbations and using only output information. To achieve this, first, an extended high-order sliding-modes observer estimates the states and identifies the perturbations, theoretically, in finite time. Then, an active disturbance rejection scheme considers the estimated states and the identified perturbation. As a result, the closed-loop system is robust against external perturbations, and the system trajectories converge to the origin. Experimental results illustrate the performance and advantages of the presented algorithm.

This work proposes the design of a robust time-varying controller for the perturbed kinematic model of the unicycle mobile robot. The controller is based on composite Lyapunov functions applied in time-varying linear systems. The methodology ensures the stability of the tracking error despite the presence of multiplicative disturbances in the control channel. The synthesis of the proposed controller requires the solution of a set of off-line Linear Matrix Inequalities and the solution of an optimization process regarding the composite Lyapunov approach. Simulation results show the feasibility of the proposed strategy against classical controllers.

Each servo motor includes an integral action in its local control. In contrast, the input control law of the leader incorporates the speed desired reference trajectory, which will track each servo motor connected to the leader. The speed desired reference trajectory build employing a high-order Bezier polynomial-the experimental setup using the dSPACE equipment DS1104 model. The experimental results show the effectiveness and robustness of the synchronization and consensus of the control based on the differential flatness property for the group of DC servomotors.

Published: February 2024

In this paper, a hybrid wind-solar microgrid with battery storage aimed to bolstering remote and rural economies in Mexico (Alamos, Sonora and Petatlan, Guerrero) is presented. A load demand profile based on local economic activities is proposed and the optimal system sizing is obtained using a genetic algorithm (GA) and particle swarm optimization (PSO), both programmed in MATLAB, minimizing the global cost, and analyzing the cost of energy. The results are compared with a grid extension showing that schemes are feasible, since they present good stability and a lower cost than the extension of distributed networks.

This paper proposes a proportional-integral-retarded (PIR) controller for a synchronous boost converter to ensure its reliable operation during voltage regulation. The PIR controller is based on the addition of a time-delay as a design parameter. In this approach, we analyze the spectral properties of the closed-loop system and establish a tuning rule that optimizes its dynamic response, thus maximizing the exponential decay rate for the system’s solutions. Inspired by the application field of renewable energy systems such as photovoltaic and fuel-cell systems, we validate the significance of our results via numerical simulations and show that incorporating delays as design parameters improves relative stability margins.

Authors:   CENIDET, México, Rosales Arriaga Bernardino , López López María ,   CENIDET, México, Alvarado Martínez Victor ,   CENIDET, México
Published: February 2024

This paper focuses on obtaining an equivalent electrical circuit (EEC) type model for a flow battery, with parameter identification from data generated by simulating an electrochemical model of the system. The model with the EEC structure is more versatile to be used, for example, in design and testing of control and energy management strategies in hybrid systems, since it can be simulated in conjunction with other electrical circuit models of power electronics devices. The EEC model is obtained from the data resulting from the simulation of the electrochemical plant before an input signal rich in frequencies, estimating the model parameters by nonlinear least squares fitting, implemented in an algorithm available in the Matlab - Simulink platform.

Authors:   Universidad Nacional Autónoma de México, Bastidas Montiel Valentina , Camacho López Ruben ,   Universidad Nacional Autónoma de México, Ruiz Frias Edwin ,   Universidad Nacional Autónoma de México
Published: February 2024

On this paper we present a mechano-electrical system capable of scanning and acquiring images that are enhanced using Kalman filter. As photosensitive element we chose photoresistors that restrict the resolution of our system to their diameter. The whole system consists of three main parts: the scanning device, the acquiring circuit and finally an image processing stage. To process the image, we designed a Kalman Filter, that allows us to save two images, the one acquired directly from the mechano-electrical circuit and the one enhanced by the filter. Our system proposes a simple, small, low cost scanning solution that can be used as a camera for images that have little curves on their morphology.

In this paper, a direct power control (DPC) is proposed in order to improve the power dispatch in electrical power grids, as well as in microgrids. The objective of defining the active power and reactive power as state variables is to get a representation of the first level in a hierarchical control. The DPC model is studied under passivity rules, and an implementation of passivity-based control is proposed. Simulations are carried out to show the effectiveness of the proposed research.
Real-Time Control of Underactuated Systems in a Mechatronics Kit Via a Novel LMI-Based Sliding Mode Approach
Authors:   Sonora Institute of Technology, México, Bernal Miguel , Calvo César ,   Sonora Institute of Technology, México, Vázquez David ,   Sonora Institute of Technology, México
Published: February 2024

Real-time implementation of a sliding mode control scheme based on the unit vector approach, for a variety of underactuated configurations of a mechatronics kit (rotational, inertia, and double pendulum) is presented in this work. Details are given to perform diffeomorphisms leading to the required normal form, based on which design conditions are cast as linear matrix inequalities, thus improving numerical systematicness of the traditional methodology. Once the control law is designed, its implementation requires reliable estimates of the velocities since the different plants under consideration do not measure them; to this end, Levant's robust differentiator is employed. Results are provided that show the effectiveness of the proposal.

Authors:   Universidad Autónoma de la Ciudad de México, Márquez-González David , Contreras González-Olvera Marcos ,   Universidad Autónoma de la Ciudad de México, Avila-Becerril Sofia ,   Universidad Nacional Autónoma de México
Published: February 2024

In this work, an isolated single-phase microgrid based on parallel-connected inverters is analyzed to supply the power demanded by the load. A controller based on the interconnection of Hamiltonian systems with fuzzy components is proposed to attack the problem of current tracking and voltage regulation, as well as a droop controller for power dispatch. It is determined that the incorporation of a structure based on fuzzy logic improves the transient response of the closed-loop system in current and voltage monitoring. Comparative numerical results are shown to demonstrate the effectiveness of the proposed scheme.

The branch of system identification and control theory concerned about robot manipulators is adaptive control of non-linear multi-input multi-output dynamic systems which study constitutes a mature and well-founded discipline; nevertheless, there are fundamental problems open to date, one of them is to obtain a control law that is rich enough to guarantee its persistent excitation and consequently that the parametric error converges asymptotically to zero, while the tracking error converges globally asymptotically to zero. An extension of a globally convergent adaptive scheme control for a robot manipulator in the tracking of a determined trajectories with no consideration of the interaction with its environment is proposed, based on the fact that the parameter uncertainty is involved in both the tracking error and the identification error. The first control task is achieved by a feedback linearization technique that takes advantage of the structure of manipulator dynamics. The second task is achieved by a fractional order filtering technique to avoid the joint acceleration and enrich the regressor matrix in such way that is persistently exciting. Finally, the control law is expressed as feedforward compensation and a simple PD controller.

Interesse epistemológico e formação escolar
Authors: Corbiniano Simone Alexandre Martins
Published: February 2024

O domínio propriamente epistemológico pode fazer sentido na formação escolar à medida que se possa considerá-lo, porventura, como uma oportunidade de aprimoramento da atividade humana de conhecer no plano do pensamento objetivo. Cabe ao ensino escolar contemporâneo o cultivo, a seu modo, dos valores de conhecimento próprios da racionalidade moderna. O aspecto propriamente epistemológico do conhecimento remete a um corpus de experiências do espírito racional, isto é, pode-se dizer de uma história de erros e superações internas ao próprio ato de conhecer, seu objetivo final é fundar a instância do pensamento instituinte, crítico e aberto. Nesse tempo histórico marcado por revoluções científicas é preciso buscar as condições de possiblidades para conhecimentos rigorosos, e mais que nunca manter o cultivo dos interesses humanos autênticos na formação. Este artigo é fruto de pesquisa da área de Educação em interlocução com referenciais da Filosofia, tendo como objetivo refletir acerca de alguns princípios do conhecimento objetivo, suas possibilidades, problemas, e sua relação com o conhecimento na escola. De um lado é preciso manter certo afastamento do caráter imediato e instrumental do conhecimento instituído, de outro lado, cabe manter proximidade com os valores de conhecimento que as ciências teoréticas podem proporcionar, ambos os lados são faces indispensáveis à reflexão acerca da formação escolar nesse início de século.

We attended to the urgent needs of students by enacting the curriculum with integrity, doing what was most important and effective, while accommodating their classroom context (LeMahieu, 2021). We describe the steps we took, the influences on our thinking, and the resulting impact. In hopes of elevating the participating teachers’ voices, we have integrated the explicit reflections of the teachers as they responded to prompts from the mathematics teacher educator. We offer our own Six Steps to Surviving a Teaching Emergency as a way to structure collaborative professional development between mathematics teacher educators and classroom teachers.
Frames of Learning: Privileging Teacher Perspectives for Decolonizing Lesson Study for Mathematics Teaching
Authors: Brown Karie
Published: February 2024

Lesson study’s international popularity spread as a unique, agency-oriented model of teacher professional development that is context-rich and deeply rooted in teacher subjectivities. This project aimed to answer the question, what do mathematics teacher education researchers learn about teacher learning by focusing on uncertainties as they arise when the group is trying to construct new knowledge in lesson study? Using ethnographic case study, this article explores the ways one community of practice in a Chilean school negotiated evolving objectives over the course of one school year and how I as the lesson study facilitator took up roles to support collaborative meaning-making and decolonize lesson study as a professional development tool through the use of framing.

A leitura partirá dos textos de Mombaça que refletem sobre a linguagem da performance, o uso da escrita e os questionamentos a respeito do processo de enquadramento das diferenças dentro do mundo da arte. A argumentação se completa com os depoimentos das próprias artistas sobre o trabalho e a forma como compreendem sua atuação. Em paralelo, trazemos a contribuição de autores como Michel Foucault, Judith Butler, Giorgio Agamben e Sílvio de Almeida para pensar sobre o lugar dos corpos racializados em ambientes institucionalizados, levando em conta políticas de visibilidade e o direito à opacidade, conceito de Édouard Glissant que aproximamos da obra das artistas. Como apontamentos finais, observamos que a performance analisada marca as tensões em torno da ocupação de corpos dissidentes e racializados em espaços de poder, que recorrentemente os querem dóceis e controlados.
Tecendo fronteiras: uma entrevista com Edith Derdyk
Authors: Peres Shayda Cazaubon
Published: February 2024

O texto a seguir é o resultado da entrevista realizada com a artista e professora brasileira Edith Derdyk, a qual teve como ênfase a relação entre publicações de artistas e a caminhada como processo poético e pedagógico. Além dessas temáticas principais abordadas, a artista descreve parte do seu processo criativo e poético, revela algumas de suas referências filosóficas, teóricas e artísticas. Mesmo ao trabalhar com diferentes materiais e suportes, salienta ser o fio condutor de sua poética a “linha”, que ora se apresenta em forma de desenho, escrita, livro de artista, escultura, instalação ou no deslocamento físico do corpo da própria artista.
Entrevistas-passo: um livro de artista em deslocamentos pela cidade
Authors: Moreira Vânia Medeiros
Published: February 2024

Este artigo revisita o método das entrevistas-passo, que deu origem ao livro de artista Cidade Passo, anos depois de sua publicação, propondo uma releitura que desloca o trabalho de sua aproximação inicial com a etnografia em direção à noção de educação da atenção. No desenvolver desta análise, relaciono as entrevistas-passo com a imagem das "figuras de barbante" (string figures) proposta por Haraway para pensar sistemas colaborativos entre seres vivos e com a noção de percurso a pé enquanto desenho e objeto arquitetônico, a partir das reflexões de Jacques e Careri. Por fim, reescrevo uma das experiências feitas no contexto de produção do livro em São Paulo e proponho um diálogo desta como um novo trajeto, feito em 2020, em Salvador, lançando mão um modo de uma escritura em primeira pessoa que se identifica com a noção de “escrita acadêmica f(r)iccional”.
A publicação de artista como estratégia descolonial
Authors: Lacerda Eva Alves , Oliveira Matheus  Ezequiel de
Published: February 2024

Diante das possibilidades de produção e circulação artísticas que as publicações de artistas apresentam, neste artigo, abordamos a potencialidade descolonial destas produções como alternativa aos espaços de arte institucionalizados. Para isso, elaboramos o seguinte problema investigativo: como a publicação de artista pode funcionar como prática descolonial de circulação artística fora dos espaços oficiais de arte? Para responder a esta pergunta, elaboramos uma pesquisa bibliográfica que objetiva discorrer sobre o sistema de arte como herança colonial; conceituar publicação de artista e sua fruição em espaços não convencionais como prática dissidente; e, por fim, apresentar proposições artísticas de circulação que extrapolam os espaços de arte institucionalizados. Os resultados desta pesquisa indicam que as publicações de artista colaboram para democratizar o acesso à experiência estética propondo meios de circulação, consumo e produção alternativos ao sistema de arte institucionalizado.

O presente trabalho apresenta uma ação de extensão envolvendo o tema dos agrotóxicos. Este tema vem sendo bastante desenvolvido, tanto em atividades de ensino, como de extensão. Contudo, o diferencial da ação aqui relatada é que ela foi toda planejada para ser acessível para as comunidades surda e cega, trabalhando de forma dialógica e com criticidade (conforme Paulo Freire) o modelo de desenvolvimento agropecuário brasileiro, especialmente o uso intensivo de agrotóxicos. A partir do documentário “Nuvens de Veneno”, foram criados materiais acessíveis: janela de Libras no documentário; estruturas químicas dos princípios ativos impressas em 3D e em alto relevo com inscrições em Braille e audiodescritas; e um folheto impresso e audiodescrito, contextualizando os problemas causados ao meio ambiente, à saúde humana e animal. Todo este material foi utilizado durante a atividade na Semana Nacional de Ciência e Tecnologia. A ação foi realizada tanto num estande durante o evento, na Universidade Federal do Rio de Janeiro, como no território de uma escola estadual, durante as aulas de química de seis turmas do Ensino Médio. Durante os dois dias de exposição no estande, a atividade gerou interesse de um público variado, desde crianças do ensino fundamental, professores - que levaram suas turmas - bem como de um grupo de estudantes surdos. No território da escola, a atividade movimentou as turmas de maneira contundente, trabalhando a química dos agrotóxicos, a preocupação social e ambiental, incluindo alunos refugiados, com deficiência intelectual, autismo e transtornos cognitivos e intelectuais.
Vozes não mais veladas: a importância do diálogo e da escuta ativa dos acadêmicos de medicina na educação em saúde sobre a sexualidade e prevenção da aids na população idosa
Authors: Moutta Jéssica de
Published: February 2024

A temática da sexualidade na terceira idade é repleta de preconceitos, estigmatização e discriminação, advindo dos mais diversos setores sociais. Esta alocação de dessexualização dada pelo ideário social à população geriátrica contribui, sobremaneira, para a desinformação sobre a prática sexual segura por este grupo. Sob essa perspectiva, os dados do DATASUS de 2019 refletem esse cenário ao mencionar que foram registrados cerca de 1059 óbitos de indivíduos pertencentes à população idosa, dentre as 7773 mortes ocasionadas por complicações advindas da infecção pelo HIV. Logo, frente a esses dados, faz-se necessário cada vez mais a realização de ações que visem a promoção e a educação em saúde para a pessoa idosa. Com esse objetivo, a partir das vivências dos estudantes do curso de medicina com os idosos do grupo “Idosos da Alegria de Viver, por meio da aplicação do questionário Sexualidade na Terceira Idade e da distribuição de cartilhas que abordavam sobre os principais pontos sobre o vírus HIV e a AIDS, foi possível implementar ações educativas para esse público em questão. Desse modo, por meio do diálogo e da escuta ativa dos participantes da pesquisa, os estudantes puderam extrair que cerca da metade dos entrevistados expressaram não saberem como proceder mediante a uma possível infecção pelo vírus HIV e desconhecerem sobre a profilaxia pré-exposição ao HIV, demonstrando assim, as lacunas presentes na área da saúde. Logo, com a participação dos acadêmicos no projeto de pesquisa foi possível possibilitar ao estudante vivenciar experiências de implementação de ações educativas em saúde para o público-alvo, de modo a contribuir para o aperfeiçoamento do relacionamento médico-paciente e da escuta ativa mais humanizada assim como do diálogo intergeracional dos médicos em construção com seus futuros pacientes. Dessa maneira, as vozes das pessoas idosas que eram veladas passaram a ser escutada por todos, inclusive, pelos profissionais da área da saúde, seja durante a formação, seja após a formação, porque todo ser humano tem o direito de escuta.
Diskursraumschutz durch hochschulisches Ordnungsrecht
Authors: Eisentraut Nikolas
Published: February 2024

Die Hochschulen waren von Beginn der bundesdeutschen Geschichte an Austragungsort politischer Konflikte. Ihre große Stärke liegt darin, ein Forum für die Versachlichung, wissenschaftliche Vertiefung und Reflexion dieser Konflikte zu bieten. Die Konflikte in den letzten Jahren haben jedoch plastisch gemacht, dass dieses Ideal eines wissenschaftlichen Forums kein Selbstläufer ist, sondern Steuerungsleistungen aller Organe der Hochschulen bedarf und häufig auch Präsidien und Rektorate in die Pflicht nimmt, Auseinandersetzungen zu begleiten, zu gestalten und ultima ratio auch Grenzen zu setzen.
The CJEU’s Feminist Turn?
Authors: Steininger Silvia
Published: February 2024

In Case C-621/21, the Grand Chamber of the Court of Justice of the European Union (CJEU) held that women in general and women facing domestic violence in their country of origin in particular, qualify as a protected ‘social group’ under EU Directive 2011/95 and thus avail themselves for refugee status or subsidiary protection in the Common European Asylum System. This contribution applies the perspective of feminist approaches to international law to critically analyze what this decision means for women and victims of gender-based violence – in- and outside of the European Union.
