Published: July 2022

Desde los años ochenta, la situación política de Venezuela ha generado una crisis nacional que se ha visto reflejada en la migración de más del 5% de la población en su mayoría a Colombia y Perú. Esta situación presenta dos problemáticas para Colombia. La primera se refiere a la ausencia de datos actualizados porque no se cuenta con la infraestructura para recoger la información necesaria. La segunda es la larga extensión de la frontera colombo venezolana, encontrando particularmente que en Norte de Santander se encuentra el mayor número de venezolanos en Colombia. Por esto, el objetivo de esta investigación es estudiar la situación de los venezolanos migrantes en este departamento. Para lograr este objetivo se planteó una metodología cualitativa, basada en un estudio de caso único en el municipio de Ocaña. En donde se realizó observación, revisión documental y encuestas, lo que permitió la caracterización de la población.
SYNANTROPIZATION OF STELLER SEA LION (EUMETOPIAS JUBATUS, SCHREBER, 1776) IN KAMCHATKA WITHIN THE LIMITS OF PETROPAVLOVSK-KAMCHATSKY (RESULTS OF 20-YEAR-LONG MONITORING)

Published: July 2022

The problem of adaptation of the Steller's northern sea lion (Eumetopias jubatus, Schreber, 1776) to the coastal water area adjacent to the town of Petropavlovsk-Kamchatsky is presented in the article. There are two stages in the sea lion synanthropization. The first stage is associated with rookeries formation, foraging near vessels and in the bay in area, in the usual habitat of these animals, in seawater. The second stage is connected with pioneering a new habitat and feeding on land. During sea lion adaptation to new conditions over a 20-year peri-od, the fear of humans noticeably decreased in animals, new behavioural traits such as cadging appeared. The group of sea lions wintering in Petropavlovsk-Kamchatsky during the 20-year period was characterized by sta-tistically significant fluctuations in numbers by year and season. The further coexistence of wintering animals depends on the dynamics of the influence of both natural and anthropogenic factors.

When metaphor can be seen in the Noble Qur'an from several aspects, such as the definition of metaphor among classical and modern scientists, and explaining its development, its pillars, values, division, and role in the meaning of each expression, as well as displaying the value of balaghah in isti'arah contained in the verses of the Qur'an, the authors analyze and conclude this data in the aspect of translation by referring to the interpretations of the Qur'an and balaghah books. After the researcher made observations on the translation of the verses of the Qur'an which contained metaphors of various types, the researchers obtained two-sided conclusions, some translations matched the translation criteria and some that did not. And this happens because of the translator's lack of attention to the general metaphorical values contained in it. While metaphors make a great contribution to the understanding of the verses of the Qur'an with the understanding of their true meaning to the Arabs. And the translation of the verses of the Qur'an without paying attention to isti'arah will give birth to lafaz that do not contain the intended meaning and will not enter into the true understanding.
Online Brazilian Journal of Nursing has a new site and a new way of management
Authors: Cruz Isabel Cristina Fonseca da
Published: July 2022

The OBJN joined to the Public Knowledge Project. Now, the OBJN utilizes the Open Journal Systems(OJS) software, a journal management and publishing system. The OJS helps the OBJN ́s editor from managing submission reviews through to online publication and indexing. It was possible because the OJS is made freely available to open access research journals. The OBJN believes that open access publishing at the WWW can increase a journal's readership as well as its contribution to the public good on a global scale. It is important to point out that in Brazil the OJS was translated and adapted by the IBICT. The OJS become the Sistema Eletrônico de Editoração de Revistas (SEER). The new OBJN with the OJS or SEER management system is very simple for the journal editors, authors, reviewers or management staff. What will change now a days?

In this article the nursing knowledge standards were described with the intention to facilitate the assistance planning given to adolescents in risk for the human immunodeficiency virus and the acquired immunodeficiency syndrome. Such planning allows the nurse to foresee and to establish the nursing lapsing, the costs of the activities and the human resources for its implementation. Nursing Knowledge Standards — Empiric, Estetic and Ethic, were organized by Carper in 1978 after nursing has been structured by Florence Nightingale in 1850 when she had established the education structured for the nursing. What can be concluded is that promote nursing assistance for the adolescents focused on in the HIV and aids prevention will be able at the apply these standards for a better assistance comprehension to this population.

Genetics and nursing: nurses' role in the oncogenetics counseling and in the molecular study of hereditary breast and ovary cancer syndrome
Authors: Santos Milena Flória
Published: July 2022

Genetic counseling has appeared in the nursing literature since the early 1960, and it became part of nursing standardized language when it was included in the Nursing Interventions Classification, being defined as an interactive helping process, a communication and educational intervention, focusing on assisting an individual, family or group, manifesting or at risk for developing or transmitting a birth defect or genetic condition. During genetic counseling clients receive information and education about genetic tests, benefits, risks, and meaning of tests results. This study proposed, for the first time in Latin America, the implementation of the nursing process, through nursing consultations, for clients in the oncogenetics counseling process for Hereditary Breast and Ovary Cancer Syndrome (HBOC). The conceptual model of Wanda Horta was adopted as theoretical framework and the case study method was used for 11 women with HBOC selected among a sample of 1168 individuals, during 2001-2003. Genetic tests for mutation detection in geneBRCA1 were performed by DHPLC (Denaturing High Performance Liquid Chromatography), PTT (Protein Truncation Test), and direct sequencing. Nursing diagnosis of knowledge deficit was observed in all clients, and the strategy of teaching and learning was used in the phases of planning, implementation and evaluation of the nursing process. All 11 clients presented alterations in BRCA1 gene. Six individuals presented IVS8-64delT variant and S1436S, four presented IVS16- 68A>G variant, and case 11 was the only one who also presented other three alterations, IVS8- 57delT, IVS18+66C>A, and the S1613G. These results suggest that these families could share the same haplotypes, sharing the same ancestral group. These techniques can identify a Brazilian panel of mutations. Incorporating molecular data, and genetic counseling as a part of the nursing process can provide important components of health care for families with hereditary breast cancer at oncogenetics services in Brazil.
The teaching of gerontogeriatric nursing in Brazil from 1991 to 200 seen under the complexity of Edgar Morin
Authors: Santos Silvana Sidney Costa
Published: July 2022

The present study had the following objectives: to identify the characteristics of gerontogeriatric nursing such as exhibited on Brazilian Nursing Journals; and to draw a reflection on the teaching of gerontogeriatric nursing in undergraduation courses, based on identified characteristics as seen under the Complexity of Edgar Morin. A qualitative research, it had as a data-source 9 proceedings volumes of Brazilian Nursing Congresses (281 abstracts, of which 260 are on gerontogeriatrics and 21 on the teaching of gerontogeriatric nursing), plus 7 national nursing publications: “Revista Texto e Contexto em Enfermagem”, “Revista da Escola de Enfermagem da USP”, “Revista Gaúcha de Enfermagem”, “Revista Enfermagem da UERJ”, “Revista da RENE”, REBEN, “Revista Latino-Americana de Enfermagem” (186 Journal issues of which 88 articles on gerontogeriatrics and 9 covering the teaching of gerontogeriatric nursing) for the 1991-2000 period. The main body of this article comprised 16 scientific articles on the teaching of gerontogeriatric nursing, where software was used for a qualitative analysis – QRS- NUD*IST4. Results made possible to perceive teaching during the research period conducted as: the mandatory subject, the introduction of specific contents in various subjects, the participation on extension work, and extra-curriculum training stages. Contents were presented through the themes: the aged; growing old; old age; gerontology and geriatrics; gerontogeriatric nursing turned to conceptual aspects; work process, nursing process, care to the elder – in houses for the aged, dependent and undergoing surgery, family care, care given to family carers, and care given at home. Such findings strongly support the thesis that Brazilian nursing already understands the gerontogeriatric field as a void still to be filled, requiring roads for an autonomous and/or multidisciplinary team work professional action, and interdisciplinary and/or transdisciplinary work. To think of the teaching of gerontogeriatric nursing or any other subject matter, in Nursing, using the Principles of Edgar Morin’s Complexity is tantamount to perceiving educative teaching as trying to convey a culture enabling the future worker to: understand the human condition; think in a contextualized, open, globalized, ethics, dialogic, recursive and hologrammatic form; and, to direct this worker towards: acquiring qualifications, learning how to do research, to develop practical classes and/or training stages, and other activities turned to the care of the elderly, reconnecting the various knowledges with other disciplines, having as the main target of this educational teaching the human, professional, and ecological care.

Published: July 2022

The present study was realized with the objective to evaluate, under the perception of the user, the importance of the social participation to control and improve the health services in the county of Camaragibe, state of Pernambuco. Thus, a questionnaire of open and closed ended questions was prepared. The survey involved 789 users that were inquired about the utilization of the local health services in the last six month that preceded the inquiry. It was verified that the mechanisms of participation, as well as the correlated legislation are not well known nor used by the users. Nevertheless, the percentages of those who utilize these mechanisms of social participation increase according to their educational level. It has been noted that educated individuals who are involved in community associations, have a tendency to use those services in a more effective manner. The users of private health services showed a higher percentage of satisfaction compared with those who depend on the public services. Nevertheless, the level of contentment of the public service users showed that it was significantly increased, not reflecting, however, a high pattern of quality, the reason being, it is justified by the low expectation of those who depend on public services. The identification of barriers and opportunities of the user's participation to control the quality of health services has to be faced with an ethical compromise of the administration members and one essential element exercised by the upstanding law abiding collective community.

Published: July 2022

A Unidade de Terapia Intensiva Neonatal é um local com aparatos e com equipe especializada, destinada ao atendimento do recém-nascido de alto risco, contribuindo para redução dos índices de morbi-mortalidade e de seqüelas em recém-nascidos. Isto gera nos pais medo, ansiedade e expectativas na assistência destinada ao seu filho. Embora os pais percebam a importância da assistência afetiva ao filho em situação de hospitalização, entendem suas limitações em relação aos cuidados profissionais que a criança necessita para sua recuperação. Neste sentido, torna-se necessária à relação de ajuda do enfermeiro aos pais que perpasse pela compreensão, confiança e habilidade, para dispensar cuidados adequados ao recém-nascido durante e após a hospitalização, bem como preencher suas necessidades práticas e emocionais.

Ethics of care in public health educative actions - a literature review
Authors: Pedro Eva Neri Rubim , Cabral Fernanda Beheregaray , Colomé Juliana Silveira , Cocco Marta , Soder Rafael Marcelo , Crossetti Maria da Graça Oliveira
Published: July 2022

This paper analyses ethical aspects of care within the context of public health educative actions by highlighting the practice of nursing professionals from reflections and inquiries regarding the ethical dimension of care. The ethical relations of care imply human relationships and, consequently, complex relations. Therefore, it is necessary that each subject be respected and welcome according to his/her needs what requires the construction of ties, between the professional and the patient, regulated by ethics and respect. Finally, it is pointed out that ethics in nursing pervades a holistic view of the human being what allows the nurse to recognize his/her competences and responsibilities with the patients. It is up to these professionals to take over their commitment as health educators within this process of social reconstruction by struggling for the fulfillment of public health policies and by overcoming the assistance practice and by rescuing the quality in the attendance of the population by means of competent, responsible and humanized nursing care.

Published: July 2022

This transversal, descriptive, and analytical study attempts to identify the levels of pressure for a determined population of adolescent students and the risk indicators of significant association for arterial hypertension. The research was developed in a public school of the capital of the state of Maranhão, Brazil, with a sample size of 302 adolescent students. The data was collected using questionnaires with open and closed questions. Of the total number of adolescents who participated, 2.7% presented arterial hypertension, the greatest number of these within the age group of 14 to 17 years old, and predominantly masculine. In this study, after the statistic analysis, the association of arterial pressure behavior with gender, age, and nutritional situation did not show significance (p> 0.05), even though there was scientific corroboration among these variables as risk indicators for arterial hypertension. Smoking and the type of nourishment showed to be risk factors for arterial hypertension with (p

Published: July 2022

Organizing professional training of the workers for social work practice and providing social services is poorly studied aspect of professional training for adults in Ukraine. This article presents the results of the desk study focused on systematic analysis of documents that define the particularities of organization of professional training of the workers in the field of social work. Two directions of professional social work training were identified: 1) advanced qualification training that suggests that a person takes professional educational courses with certain frequency on certain positions and receives approved certification document; 2) preservice, on-job training of the workers that is focused on developing professional competences the workers need to perform their functions. The categories of the workers for professional training, their rights and conditions for receiving a certain type of professional training were defined. The list of entities operating in advanced competence and/or qualification development for social work practice and providing social services, key providers of professional training services, their organizational forms, their subordination and authority were identified. Also, criteria and requirements for educational programs that are used for professional training were defined. It was observed that there is a big number of professional training providers that are responsible for development and implementing programs of advanced competence and/or qualification development and at the same time there is a lack of relevant available programs for workers in the field of social work. At the time when majority of workers do not have basic professional qualification in the field of social work and need forming and developing professional competencies necessary for effective work based on best practices, the actual providers of educational services position themselves as entities of advanced qualification training and still do not offer programs that are needed by practitioners. It was detected that legislative regulations of advanced professional competence or qualification training of the social workers need improvement: functions and powers coordination of entities of professional training, implementation of procedures of training needs assessment, developing the content of educational programs and providing the mechanisms of funding of training. Separate attention needs to be paid to reviewing the priorities in the work of professional training provides to increase the access of the social workers to regular preservice, on-job training for performing their on-job functions that correspond to the training needs of those specialists.
HOTLINE SERVICES FUNCTIONING DURING A PANDEMIC
Authors:   Taras Shevchenko National University of Kyiv, Tokhtamysh Oleksandr , Zatsepina Irina ,   Taras Shevchenko National University of Kyiv
Published: July 2022

Hotline services remain a responsible component of suicide prevention and an important part of psychosocial counseling during the period of rapid development of information technologies and social networks. The COVID-19 pandemic throws new challenges to hotline services due to forced restrictions on direct communication between people. The most important functions of remote counseling services during this period are to inform about safe behavior during a pandemic, and to reduce anxiety and stress, the absence of health and life hazards, restrictions on joint communication and the need for isolation and removal. As a result of the analysis of information available through Internet search engines, there are currently about 30 hotlines in Ukraine, which provide consulting services both for certain categories of client and for all comers. There are four specialized national hotlines in Ukraine, which are operated by non-governmental organizations. Regarding the models of organization of hotlines in Ukraine, in contrast to Western European countries, where the volunteer model predominates, the professional model is mostly presented, i.e., the organization on the basis of professional counseling of specialists such as psychologist, medical doctor (usually psychiatrist), lawyer, social worker, pedagogue, etc. In some services, "peer to peer" model of counselling is present at the same time as professional counseling, in particular, on the National HIV / AIDS hotline and Lifeline Ukraine for veterans. During the pandemic period, new hotlines have been established, in particular in countries such as China, the United States, Brazil, and Ukraine, and a significant increase in the number of hotline calls (Germany, Austria). We interviewed 23 respondents, including 10 professional hotline consultants and 13 hotline volunteers. According to the respondents, during the pandemic period, the number of requests related to information about COVID-19. There is a lot of inaccurate information in the information space about coronavirus treatment, vaccination, the requirement to use personal protective equipment, the importance of state quarantine restrictions and the requirement to limit physical contact with other people. Therefore, the hotline consultants have a new task – to provide reliable and verified information on the spread of COVID-19, the importance of contacting a family doctor in case of ill health, debunking myths and fakes. In Ukraine, there is an increase in appeals from people belonging to "at risk" groups – the elderly, health care workers, people with chronic diseases who have fears and feelings about physical and psychological well being. There has also been an increase in calls about domestic violence and other domestic problems. The rise of the volunteer movement, which could observed in Ukraine since 2014, has given impetus to the wider introduction of the volunteer model in the field of hotline services also during the pandemic.

Published: July 2022

Objective: Bruxism is defined as a parafunctional activity. It could be in diurnal or nocturnal form, based on the time it occurs. The purpose of the study compares the effectiveness of occlusal splint treatments in children with nocturnal bruxism using the BiteStrip®. Study Design: The muscle activity of children was measured using the BiteStrip®. The groups used occlusal splints during nighttime sleep for three months, at the end of which their muscle activity were measured again through the use of the BiteStrip®. Results: Muscle pain in palpation and pain in the dynamic position of TMJ pain was significantly reduced in patients using soft occlusal splint (p=0.01). There was no significant change in the BiteStrip® score in both group I (p=0.11) and group II (p=0.61). Conclusion: Soft occlusal splints could reduce pain caused by nocturnal bruxism on muscle and TMJ. The relationship between treatment results and BiteStrip® scores of patients using soft occlusal splint or hard occlusal splint are not significantly.
Post-industrial Culture of Law-making: a New Image of Reality
Authors: Zaloilo M. V.
Published: July 2022

The leading factor of the transformation of the legal sphere of post-industrial society is the technological challenges that create risks of technological and legislative singularity. The legal culture is transformed in connection with the formation of a new worldview and legal thinking. The purpose of the study is to determine the factors, patterns, prospects and risks of transformation of the culture of law-making in post-industrial society. The result was the identification of factors of the transformation of the culture of law-making. The increase of the technological component in the composition of the law-making culture of post-industrial society has caused such patterns of its transformation as the symbiosis of legal and digital technologies, the blurring of the lines between the object and the subject, the object and the result of law-making. Prospects for further transformations of the culture of law-making are revealed — acquiring new functions, transforming the system of law and restructuring its sources, innovations in the subject and object composition, stages and technological component of law-making, its inherent terminology. Human-machine interaction, hybridization as the main features of the emerging “digital” culture of law-making not only has advantages, but also carries serious risks, the management of which, along with the proactive impact, becomes the most important function of the law-making culture of post-industrial society
Diffuse Deformation and Surface Faulting Distribution from Submetric Image Correlation along the 2019 Ridgecrest, California, Ruptures

Published: July 2022

The 2019 Mw 6.4 and 7.1 Ridgecrest, California, earthquake sequence (July 2019) ruptured consecutively a system of high-angle strike-slip cross faults (northeast- and northwest-trending) within 34 hr. The complex rupture mechanism was illuminated by seismological and geodetic data, bringing forward the issue of the interdependency of the two fault systems both at depth and at the surface, and of its effect on the final surface displacement pattern. Here, we use high-resolution (WorldView and Pleiades) optical satellite image correlation to measure the near-fault horizontal and vertical surface displacement fields at 0.5 m ground resolution for the two earthquakes. We point out significant differences with previous geodetic- and geologic-based measurements, and document the essential role of distributed faulting and diffuse deformation in producing the observed surface displacement patterns. We derive strain fields from the horizontal displacement maps, and highlight the predominant role of rotation and shear strain in the surface rupture process. We discuss the segmentation of the rupture based on the fault geometry and along-strike slip variations. We also image several northeast-trending faults with similar orientation to the deeply embedded shear fabric identified in aftershock studies, and show that these cross faults are present all along the rupture, including at a scale <100 m. Finally, we compare our results to kinematic slip inversions, and show that the surface diffuse deformation is primarily associated with areas of shallow slip deficit; however, this diffuse deformation cannot be explained using elastic modeling. We conclude that inelastic processes play an important role in contributing to the total surface deformation associated with the 2019 Ridgecrest sequence.
A Phenomenological Exploration of Comprehensive Exam Efficacy to Understand Student and Faculty Perception about its Influence on their Learning Outcomes and Teaching Efficacies
Authors:   , Connolly Chris L. , Vaidya Sheila
Published: July 2022

The purpose of this phenomenological study is to explore and examine the influence of a comprehensive exam assessment instrument on student learning in a professional military education (PME) program. While the U.S. Army Command and General Staff School (CGSS) has adopted a summative assessment to evaluate student learning at the end of their PME program, additional research is needed about how a comprehensive exam affects student attitudes regarding autonomy, resilience, motivation to learn, as well as faculty attitudes about self-efficacy. This research began from a pragmatic constructivist paradigm and used a phenomenological approach to examine the effects of the exam on former student and former faculty experiences, which included motivations on learning, resilience, self-efficacy, and the use of comprehensive exams as an assessment tool. Literature threads included military officer student attributes, motivations, and resilience; followed by a second thread that examined instructor self-efficacy. The final thread of the framework examined differing perspectives on the efficacy of comprehensive exams as part of assessing student learning, especially at the graduate level. Data was gathered using semi-structured interviews, observations of a study group, and a researcher's journal, followed by analysis for emergent themes and trends. The study's results indicate that misaligned initial expectations between former student participants, former faculty participants, and the purpose of the comprehensive exam have impacted motivations to learn and self-efficacy. Further, emotional reactions to various interactions within the course have shaped student perceptions and motivations, and that their judgement on the value of learning, teaching, and the exam was largely driven by how they made sense of the experience. Recommendations for practice include developing an improved method for sharing understanding of the purpose of the comprehensive exam early in the course and then cultivating emotional intelligence skills within instructors to manage student expectations. A corollary effort would be to provide students a useful assessment of their initial study skills; participants discovered their shortcomings too late in the course. As well, adding comprehensive written feedback from the comprehensive exam to student portfolios should be considered. Future research could examine how the inclusion of a comprehensive exam impacts the Army's desire for a learner-centric curriculum; as well as examination of the impact of the feedback that students receive from their oral board performance as it relates to the Army's requirement to develop life-long learners.

Wood has some weaknesses, such as susceptibility to weathering, easily attacked by termites, and low water resistance. An alternative material such as Natural Fibre-Reinforced Polymer (NFRP) composite should overcome those weaknesses. This research aims to make a composite with palm fibre and unsaturated polyester resin. Palm fibres immerse for 2 hours in NaOH solution with varying concentrations of 3%, 5%, and 7%. The volume fraction of palm fibre are 0%, 5%, 10%, 15%, and 20%. Woven roving fibreglass was added to compare the tensile strength of composite with or without natural fibre. The density of composites increased with the increase of fibre volume fraction. The highest tensile strength was obtained for 15% of fibre volume fraction, namely 23.8483 MPa. In contrast, the highest compressive strength was obtained for 5% of fibre volume fraction, namely 94.76 MPa. NaOH removed the impurities and waxy substances from the fibre surface and created a rougher surface topography after alkalization. The highest tensile strength was obtained with 7% NaOH, namely 14.674 MPa. The highest water absorption value was obtained at 3% NaOH concentration and 15% of fibre volume fraction, namely 1.445%. The addition of woven roving as reinforcement to natural fibre composite can increase tensile strength by 210%, from 13.882 MPa to 43.123 MPa.

The structure, image, and vibrational spectra of the materials were investigated respectively by XRD, TEM, and FTIR characterizations. Based on XRD characterization results, both undoped and Co-doped Ni – Zn ferrite possesses a single-phase formation, namely spinel structure without any impurities from other phases. The lattice parameters of Co-doped Ni – Zn ferrite is 8.419 nm which is higher than undoped Ni – Zn ferrite (8.409 nm). Meanwhile, the average particle size obtained based on the results of the TEM characterization is 14.4 nm with slight agglomeration. The results of FTIR characterization on all samples provide information on the presence of metal ion vibrations at frequency bands about 493.78 cm-1 located at the tetrahedral and 514.99 cm-1 occupied at octahedral sites. Those frequency ranges confirmed that both samples have spinel structures.

An Optimal Quantitative PID Controller Design for Ball and Beam System
Authors: Ali Hazem I. , Ibrahim Ibtihal H.
Published: July 2022

In this paper, the design of two degree of freedom controller for ball and beam system is proposed. The Quantitative Feedback Theory (QFT) constraints are used to design two PID controllers to stabilize and compensate the nonlinear system with robust stability, robust performance and more desirable time response specifications. A multi objective cost function is proposed in this work to represent the function of QFT. The Black Hole Optimization (BHO) technique is a useful method to automate the design procedure of the proposed controller. The results of simulation indicate that the suggested optimal quantitative PID controller can give a desirable performance in comparison to other controllers designed in previous work.
Design a PI Controller Based on PSO and GWO for a Brushless DC Motor

Published: July 2022

Recently all the moving mechanical parts that are subjected to wear and cause errors in the future are replaced with the equivalent of electrical. A Brushless Direct Current (BLDC) motor is preferable compared to a brushed DC motor because it substitutes the unit of mechanical commutations with an electronic unit, enhancing dynamic properties, noise level, and efficiency. Since it is fairly inexpensive, simple in structure, and performs well, maximum BLDC motor drives use a Proportional-Integral PI controller for controlling the machine's speed. The major issue with the PI controller, on the other hand, is altering its parameters throughout the deployment. As a result, this work shows how to tune the PI controller settings of a BLDC motor drive using Grey Wolf Optimization (GWO) and Particle Swarm Optimization (PSO). The results of a comparison of PSO and GWO for BLDC motors were obtained. Simulation tests for the BLDC engine in MATLAB/Simulink environment show that both PSO and GWO of BLDC motor give good results, but the best is GWO in tested in terms of transient response under different mechanical loads and speeds.

In Earliness-Tardiness (E/T) scheduling approach, the Just-In-Time (JIT) schedule is a schedule with zero earliness and zero tardiness. However, this is an optimal schedule and even notional in some instances where tardiness and earliness are inevitable. However, minimizing the deviation at the upper region (tardiness) and the lower region (earliness) from the JIT schedule is a challenge. This work proposes solutions. Two proposed heuristics; TA1 and TA2 as well as some existing heuristics were explored to solve simulated problems ranging from 5≤n≤400 and the results obtained were benchmarked against the JIT schedule. The results obtained show that one of the heuristics, TA2 yielded JIT schedules for many problem sizes at the lower and upper deviation than other solution methods.

Mission Profile Emulator for MMC-based Battery Energy Storage Systems

Published: July 2022

In recent years, Modular Multilevel Converters (MMC) have been widely used in medium/high voltage applications, such as high-voltage direct current (HVDC) systems, and pointed out as a promising solution for battery energy storage systems (BESS) and static synchronous compensators (STATCOM), according to recent research. Especially, in BESS application, the current and voltage conditions in the battery bank are fundamental to evaluate thermal dynamic, reliability, and lifetime. However, depending on the voltage and power levels, MMC is based on hundreds of SMs. Thus, the full MMC system implementation can be costly and complex for operational and reliability tests. In this sense, the so-called mission profile emulators (MPE), have been developed to emulate the voltage and current in an SM and batteries. The MPE eliminates the need to implement the full converter and contributes to more agile tests of the MMC dynamics, resulting in the design of more reliable converters. In addition, the MPE can be used to obtain battery current and arm current spectrum similar to those obtained in MMC. This work presents a detailed design and implementation of the MPE for an MMC-based BESS. The MPE is validated in simulations and in a reduced-scale prototype.

Este trabalho apresenta um método para estimar o ângulo de fase da tensão da rede baseado em um conjunto finito de ângulos - na condição de problemas de qualidade da energia elétrica em sistemas de distribuição de baixa tensão, como afundamentos de tensão simétricos e assimétricos, desequilíbrios, distorções harmônicas e variações de frequência - para sistemas monofásicos. O método é composto pelo filtro de Fourier de um ciclo (OCF) em conjunto com a técnica de posições finitas (FPS), e é chamado de PLL (Phase-Locked Loop) com Filtro de Fourier de Um Ciclo com Controle de Estados Finitos (OCF-FPS-PLL). O OCF-FPS-PLL usa um procedimento de decomposição do vetor de tensão síncrono no quadro αβ estacionário da estrutura SOGI. O desempenho deste procedimento é aprimorado por meio do filtro de Fourier de um ciclo (OCF). A tensão extraída desse filtro é então tratada por um algoritmo que é implementado por um conjunto de posições finitas (FPS) para estimar o ângulo de fase. Além disso, a estrutura SOGI utilizando o PLL no quadro de referência síncrono (SRF-PLL), a estrutura SOGI utilizando o filtro de média móvel (MAF) e a estrutura SOGI usando o filtro de Fourier de um ciclo (OCF), ambos também utilizando o PLL no quadro de referência síncrono, são comparadas. Os resultados obtidos em uma bancada experimental validam o método proposto. A principal contribuição deste trabalho é a não utilização de controladores Proporcional+Integral (PI) por PLLs para estimar o ângulo de fase da rede.
