Literatura científica selecionada sobre o tema "Usina do Almeida"

A mediação judicial do conflito no Assentamento Joana D’Arc e Usina hidrelétrica, no Rio Madeira, possibilitou estabelecer acordo indenizatório com adesão de cerca de 75% das famílias. O objetivo é analisar a mediação como instrumento emancipatório, de empoderamento e protagonismo às identidades coletivas, propiciando o espaço democrático de debate e alternativas ao conflito. Utilizou-se o método indutivo durante a revisão da literatura, com base em Sen, Habermas, Honneth, Almeida e pesquisa documental. Os resultados indicaram que a mediação visibiliza a interdependência, oportunizando o reconhecimento e o protagonismo dos envolvidos na solução do conflito, com base nos valores, necessidades e interesses.

A ação antrópica no represamento de corpos hídricos tem ocasionado a eutrofização dos recursos hídricos, e dentre os desequilíbrios que esta ação gera no meio aquático está à elevada proliferação de macrófitas. Devido a esse fato, essa pesquisa foi desenvolvida com o objetivo de realizar uma estimativa da área ocupada por macrófitas aquáticas no reservatório da Usina Hidrelétrica de Barra Bonita (SP), nos anos de 2013, 2014 e 2015. O estudo foi realizado na estação seca (mês de agosto), por meio do uso do NDVI (Normalized Difference Vegetation Index) e classificação supervisionada MAXVER (Máxima Verossimilhança). Para obtenção dos mapas e gráficos, foram realizadas as seguintes ações: seleção das imagens do satélite LANDSAT-8/OLI, calibração radiométrica, correção atmosférica, reprojeção, definição do limite, recorte da área, NDVI e classificação supervisionada. Os mapas obtidos por meio da classificação supervisionada, auxiliada pelos mapas de NDVI, apontaram para um aumento de aproximadamente 50% na área ocupada por macrófitas aquáticas de 2013 a 2015. Palavras-chave: classificação supervisionada, eutrofização, índice NDVI, landsat-8. MINHONI, R. T. A.; PINHEIRO, M. P. M. A.; FILGUEIRAS, R.; ZIMBACK, C. R. L.REMOTE SENSING APPLIED TO THE MONITORING OF AQUATIC MACROPHYTES AT BARRA BONITA RESERVOIR, SP 2 ABSTRACT Aquatic macrophytes are photosynthetic organisms, large enough to be seen with naked eye, which grow submerged, floating or on the surface of the water. The anthropic action in the damming of water bodies has caused eutrophication of water resources, and among the imbalances that this action generates in the aquatic environment is the high proliferation of macrophytes. Due to this fact, this research was developed with the aim of estimating the area occupied by aquatic macrophytes in the reservoir of Barra Bonita Hydroelectric Power Plant (SP), in the years of 2013, 2014 and 2015. The study was carried out in the dry season (August), through the use of NDVI (Normalized Difference Vegetation Index) and supervised classification MAXVER (Maximum Likelihood). To obtain the maps and graphs, the following actions were taken: selection of LANDSAT-8 / OLI satellite images, radiometric calibration, atmospheric correction, reprojection, boundary definition, NDVI and supervised classification. The maps obtained through supervised classification, aided by NDVI maps, pointed to an increase of approximately 50% in the area occupied by aquatic macrophytes from 2013 to 2015. Keywords: supervised classification, eutrophication, NDVI index, landsat-8.

Os treze textos que se apresentam nesta edição de Labor & Engenho constituem um panorama parcial do diálogo travado entre pesquisadores do Projeto Eletromemória, inclusive com parceiros que são internacionais (Portugal e Argentina), mas não estranhos à problemática brasileira, pois as empresas elétricas que atuaram no mundo latino-ibérico têm mais relações de aproximação do que costumeiramente se explicita.Este número de Labor & Engenho abre com o texto “Da usina à população na velocidade da luz: fios elétricos e desenvolvimento”, de Gildo Magalhães (do Departamento de História, USP), em que se apresenta ao público leitor como surgiu e em que consistem as duas fases do Projeto Eletromemória. O autor discorre também sobre as áreas de pesquisa abrangidas no Projeto e que são palco onde se desenvolvem os demais textos que integram esta edição, para depois esboçar em breves pinceladas o histórico da eletrificação no Estado de São Paulo, para melhor contextualizar o tema tratado.O segundo texto, “Hidrelétricas na conquista territorial e no desenvolvimento urbano em São Paulo”, de Débora Marques de Almeida Nogueira Mortati e André Munhoz de Argollo Ferrão (respectivamente pós-doutoranda e docente no Departamento de Recursos Hídricos da FEC Unicamp), explora uma tipologia das primeiras centrais hidrelétricas paulistas, dividida por décadas, de 1890 a 1930. Nesta perspectiva, as usinas e a rede elétrica compõem, em consonância com os cafezais e as ferrovias, a paisagem cultural do território paulista, num período de urbanização acelerada.“Urbanização e industrialização: rios de São Paulo”, de Odette Carvalho de Lima Seabra (Departamento de Geografia, USP) trata da história de como uma empresa multinacional (a famosa Light) foi se assenhoreando das diretrizes urbanísticas da cidade, ao influenciar o uso dos principais rios que servem a cidade de São Paulo, bem como de suas margens. Com repercussões atuais, em face dos problemas de enchentes, estiagens e produção de energia elétrica, é um trabalho que segue a linha da já clássica tese de doutorado da autora.“Paisagem: realização da essência humana. O caso das Pequenas Centrais Hidrelétricas do Estado de São Paulo do período entre 1890 a 1960”, de Eduardo Silva Bueno (pós-graduando do Departamento de Geografia, USP) se desenvolve numa perspectiva filosófica de inspiração goetheana. Fazendo uso da ideia da harmonia que deve existir para o sucesso da transformação da paisagem feita pelo homem, as pequenas centrais hidrelétricas são analisadas como unidade espacial que ordena objetos de uma relação entre o natural e o humano.Em “A cicatriz da serra: reflexões sobre as adutoras da Usina de Cubatão”, de Gabriel Carlos de Souza Santos (historiador formado pela Unicamp), temos uma análise sobre a memória daquela que foi considerada à época de sua inauguração (1926) a maior hidrelétrica do mundo: Cubatão (hoje denominada Henry Borden). Com sua construção pela multinacional Light alterou-se definitivamente a paisagem da Serra do Mar, num esforço ímpar de criação de infraestrutura, responsável pelo abastecimento de energia elétrica para aqueles que se tornariam dois polos industriais significativos, o da capital, São Paulo, e o da Baixada Santista. O autor relembra ainda a iniciativa urbanística representada pela construção da Vila Light para os trabalhadores da usina.“A construção de uma das pioneiras usinas hidrelétricas paulistas: Itatinga”, da arquiteta e pesquisadora Ana Luisa Howard de Castilho e de Itamar Barbosa Gonçalves (engenheiro da CODESP), também aborda um caso concreto e exemplar de uma das usinas hidrelétricas históricas em operação contínua desde seu nascimento. Itatinga, localizada em Bertioga, funciona desde 1910 ainda com os mesmos geradores e turbinas, implantados para a missão pioneira que foi a de movimentar as máquinas do porto de Santos e impulsionar a economia cafeeira de exportação. Idealizada por um engenheiro brasileiro, o conjunto atual da barragem, usina, vila operária e outros elementos atestam a importância deste patrimônio industrial.Itatinga é também o objeto de “Hidrelétricas na virada do século XX: tratadística e periódicos”, de Denise Fernandes Geribello (pós-graduanda da Faculdade de Arquitetra e Urbanismo da USP), em sua pesquisa, a autora identificou e documentou dois fatos essenciais: primeiro que a usina segue (com alguns pequenos desvios) os tratados de construção de hidrelétricas que circulavam internacio-nalmente no início do século 20; segundo, que após sua construção Itatinga se tornou uma referência não apenas para a engenharia nacional, mas foi assim tratada em várias publicações na América do Norte e Europa, confirmando a importância da sua preservação e de sua memória.Renato de Oliveira Diniz apresenta em “A institucionalização da memória e da história do setor elétrico paulista” uma descrição analítica dos esforços institucionais em prol da preservação do patrimônio, da cultura material e dos arquivos das empresas elétricas no país, com ênfase para São Paulo. Historiador com larga experiência no setor elétrico e cuja experiência profissional se entrelaça com a existência dessa memória, expõe ainda nesse texto suas considerações e um balanço sobre a eficácia das ações privadas e governamentais voltadas a esse campo ao longo de mais de 30 anos.Um contraponto com o artigo anterior é fornecido por “A musealização do setor elétrico em São Paulo: construção de perspectivas para as usinas hidrelétricas”, de Marília Xavier Cury (do Museu de Arqueologia e Etnologia da USP) e Mirian Midori Peres Yagui (museóloga e integrante da Secretaria de Cultura do Estado de São Paulo). A partir de um histórico do arcabouço legal brasileiro e paulista em torno do tema de museus, destacando sua aplicabilidade para o setor elétrico, as autoras fazem uma radiografia da rede de museus e dos esforços isolados que se pode associar com essa temática no estado de São Paulo. Os museus da Fundação Energia e Saneamento e outros são criticamente analisados, destacando seus aspectos de sucesso e insucesso, para ao final serem feitas importantes propostas de musealização temática em torno de uma amostra representativa das usinas hidrelétri-cas paulistas que estão sendo pesquisadas no Projeto Eletromemória, lançando ainda uma série de questionamentos vitais para que cumpram sua missão os museus em geral, e em especial os que se identificarem com o patrimônio do setor elétrico.“Uso e funcionalidade de arquivos empresariais do setor elétrico em São Paulo: o caso Light”, de Marcia Cristina de Carvalho Pazin Vitoriano e Telma Campanha Carvalho Madio (ambas docentes no curso de Arquivologia da UNESP em Marília), discute o destino dos arquivos empresariais do setor elétrico, à luz do importante caso da Light. Inicialmente organizado em função do zelo organizacional da empresa multinacional privada que lhe deu origem, este arquivo foi ampliado após a nacionalização pela estatal Eletropaulo, que estabeleceu um Departamento de Patrimônio Histórico. Após a reprivatização, o arquivo passou aos cuidados da Fundação Energia e Saneamen-to. Durante a execução do Projeto Eletromemória, descobriu-se uma parte importante e desconhe-cida desse arquivo, guardada em condições precárias pela empresa estatal EMAE, criada para cuidar da geração elétrica (usinas) da Eletropaulo, uma vez que a empresa privada AES, que comprou a Eletropaulo, se interessou em ficar apenas com a parte mais lucrativa da empresa, a distribuição de eletricidade aos consumidores.“História da eletrificação no Estado de São Paulo: um vocabulário controlado para a representação e recuperação da informação”, de Vânia Mara Alves Lima e Cristina Hilsdorf Barbanti (respectivamente docente e pós-graduanda de Biblioteconomia na USP), apresenta as diretrizes gerais que estão sendo seguidas para tratamento da informação recolhida pela equipe de pesquisadores do Eletromemória. Os termos entrarão dentro de um mapa conceitual, que servirá de base à construção de um banco de dados relacional do Projeto.“A nacionalização da electricidade em Portugal”, de Nuno Luís Madureira (do ISCTE/IUL Instituto Superior de Ciências do Trabalho e da Empresa / Instituto Universitário de Lisboa) é uma contri-buição deste pesquisador de renome internacional no campo da História Econômica da Energia. Perpassando o período ditatorial salazarista e a transição marcelista, o novo governo democrático português após a Revolução de Abril enfrentou a questão da estatização do setor elétrico. O autor demonstra que esta não foi uma trajetória linear e que a sobreposição de forças sociais e políticas aos fatores técnicos foi um processo complexo, que redundou na criação da empresa única, a EDP.Finalmente, “Fiscalização e eficiência na iluminação pública. A substituição do gás pela eletricidade em Buenos Aires (1890-1910)”, de Diego Bussola (da Universidade de Rosário, na Argentina) faz oportunas considerações sobre o conflito entre duas técnicas de iluminação pública, a gás e a elétrica. Houve países em que as empresas que defendiam essas técnicas se uniram, como em São Paulo, mas em outros países, as empresas concorrentes se digladiaram longamente, impulsionadas por fatores de custo e eficiência, cabendo a palavra final à posição decisória das autoridades municipais. O caso de Buenos Aires lança luz sobre fatores ainda presentes no dia a dia, tais como fixação de tarifas, o comportamento da oferta e demanda de eletricidade nos períodos de pico e vale, a atuação dos trustes elétricos e o papel dos órgãos públicos.Gildo Magalhães dos Santos FilhoUniversidade de São Paulo

Inspired by the work of Molino, we show that the integrability obstruction for transitive Lie algebroids can be made to vanish by adding extra dimensions. In particular, we prove that the Weinstein groupoid of a non-integrable transitive and abelian Lie algebroid is the quotient of a finite-dimensional Lie groupoid. Two constructions as such are given: First, explaining the counterexample to integrability given by Almeida and Molino, we see that it can be generalized to the construction of an “Almeida–Molino” integrable lift when the base manifold is simply connected. On the other hand, we notice that the classical de Rham isomorphism provides a universal integrable algebroid. Using it we construct a “de Rham” integrable lift for any given transitive Abelian Lie algebroid.

The political cost-effectiveness of blame-shifting strategies, which produces incentives for low-quality policy responses and creates a democratic accountability problem, becomes particularly apparent in the context of urban tragedies such as the one involving Wilton Paes de Almeida, a low-income residential building in São Paulo owned by the federal government and occupied by a low-income population. We seek to respond to the question of whether Brazil’s model of federalism requires institutional reform in order to address the blame-shifting problem using the Wilton Paes de Almeida tragedy as a case study. First, we ask to what extent can expect blame-shifting strategies to be ultimately corrected by what we call the “regulation” of Brazilian federalism through litigation. Second, we investigate whether institutional reform risks reducing current levels of democratic accountability by altering a desirable institutional framework, where citizens can turn to more than one level of government to address problems. We conclude that the institutional reform of Brazil’s model of federalism should be on the table.

This paper presents a study of the semidirectly closed pseudovariety generated by the aperiodic Brandt semigroup B2, denoted V*(B2). We construct a basis of pseudoidentities for the semidirect powers of the pseudovariety generated by B2 which leads to the main result, which states that V*(B2) is decidable. Independently, using some suggestions given by J. Almeida in his book "Finite Semigroups and Universal Algebra", we constructed an algorithm to solve the membership problem in V* (B2).

Institutions that frame social work education and prepare future practitioners are firmly rooted in hegemonic philosophies and practices that perpetuate colonization, oppression, and white supremacy. In recognizing that white supremacy is a mechanism of social control, that our current social structure is grounded in liberal-patriarchal capitalism, and that social work conforms to prevailing social norms, we, as social workers, must acknowledge our complicity in perpetuating a white supremacist master narrative (Pewewardy & Almeida, 2014). The white supremacist ideology inherent within Western social work literature, teaching methodologies, and practice strategies only serves to perpetuate an oppressive system. This structure does not envision social workers as agents of change, but rather as essential cogs of the status quo who foster client dependence on a system that is inherently marginalizing. One mechanism for disrupting the white supremacy that has become a master narrative in social work is to create a counter-narrative (Pewewardy & Almeida, 2014). This paper creates a counter-narrative by using the pyramid of white supremacy framework (Safehouse Progressive Alliance for Nonviolence, 2008; Tuzzolo, 2016) to critique social work and deconstruct post-racial fallacies ascendant within the profession, and re-visualizes ecological systems framework as a mechanism for de-centering whiteness in social work scholarship, practice, and education.

Background. Suicidal ideation among textile factory workers is a major public health concern worldwide and is associated with a higher risk of completed suicide. However, there are limited studies that determined the prevalence and the potential determinants of suicidal ideation in Africa, including Ethiopia. Therefore, this study is aimed at exploring the prevalence of suicidal ideation and associated factors among textile factory workers in Almeda textile factory in Adwa, Ethiopia. Methods. An institutional-based cross-sectional study design was conducted from May 3, 2020, to June 16, 2020, at Almeda textile factory in Adwa. A total of 409 workers were identified using a systematic random sampling technique. Data were collected using a self-administered questionnaire using suicidality module of Composite International Diagnostic Interview. Data were analyzed using SPSS version 22.0, and logistic regression model was employed. Adjusted odds ratio with a 95% confidence interval was computed, and statistical significance was declared at p value < 0.05. Result. In this study, the prevalence of suicidal ideation was found to be 8.8% (95% CI: 6.1, 11.5). Working more than 48 hours per week ( AOR = 2.88 , 95% CI: 1.18, 7.04), depression ( AOR = 3.90 , 95% CI: 1.60, 9.50), work-related physical injury ( AOR = 5.95 , 95% CI: 2.37, 14.94), and interpersonal conflict ( AOR = 3.54 , 95% CI: 1.40, 8.90) were the significant factors associated with suicidal ideation. Conclusion and Recommendation. In this study, suicidal ideation among Almeda textile production workers was a significant problem. Factors including depression, work-related exposure to physical injury, long working hour, and interpersonal conflict can enlarge suicidal ideation.

The World Wide Web (or the “Web”) is revolutionizing the concept of service -oriented computing. It permits the integration of the local area networks (LAN) and wide-area networks (WAN), thereby providing servers that are interconnected at a worldwide or an intergalactic level. Such an integration serves as a backbone for the Web-based business or e-business to access information, as well as perform e-business transactions across the globe with adequate security and reliability. In this article, we describe the issues involved in the design of an e-business transaction processing system and the solutions that have been proposed for these problems using the techniques of AI, conventional database transaction processing methodology and protocol engineering principles. These techniques will be useful for improved transaction throughput and scalability in e-commerce (Brancheau & Shi, 2001; Menasce & Almeida, 2000; Murthy, 2002).

Abstract Innovation in scientific data collection involving new kinds of protocols has proceeded at a breakneck pace over the past 10 years. Starting from a tradition of diary studies (Almeida, 2005; Bolger, Rafaeli, & Davis, 2003), researchers have increasingly used emerging “smart” electronic devices to collect data reflecting experience over time in real-life contexts. Many scientific studies have emerged using these devices; for example, there are studies using beepers for diary data collection (Csikszentmihalyi & Larson, 1987), computerized ambulatory recording devices (e.g., Wilhelm, Roth, & Sackner, 2003), automated behavioral observational tools (e.g., Borrie,Jonsson, & Magnusson, 2002; Hirschhauser, Frigerio, Grammer, & Magnusson, 2002), and sensing devices in physical and architectural environments (Intille, Chapter 16, this volume). Consistently, in many areas of psychology and in behavioral medicine, studies using Ecological Momentary Assessment (EMA) techniques have become commonplace (Stone & Shiffman, 1994). At the same time, other technological advances, including developments in GPS and GIS technology, fMRI and PET imaging, road network analysis, Web interfaces for transactions, and many other technology-based data collection mechanisms have equipped researchers with tools to collect much more detailed and complex time-graded data than ever before.

This study aims to analyse the novel O Arco de Sant'Ana, by Almeida Garrett, one of the most important Portuguese writers of the 19th century. O Arco de Sant'Ana is a historical novel that describes a medieval narrative that is used as a context and emphasis for the presentation of the author's liberal ideas of his time. Using geographical information system as a methodological tool, a literary cartographic analysis will be conducted by identifying places, streets as well as tangible and intangible heritage, described in the novel. Several analyses will be performed to pinpoint the places where the medieval narrative occurs, transposing them to the current urban map. In this way, it should be possible to overlay the literary landscape onto the present map of Porto to offer the tourist a new product based on a journey through time based on the writer's literary work.

This text is an excerpt from the master's research that aims to evaluate good practices and references on the success of the Pedagogy of Presence in the teaching-learning process in a full-time school, also known as a full-time school, located in the municipality of Várzea Grande/MT . This is a qualitative research of the case study type and the data were obtained through an interview with teachers and students of the referred school. For data analysis, categories were built in the light of Bardin (2016) and the theoretical contribution will be based mainly on Freire (1998), Costa (2001) and Almeida (2020), who discuss human relationships, based on affective education and reflective educational practices. Therefore, it was possible to observe that both teachers and students understand the correlation between affection and learning by applying the Pedagogy of Presence as constructive and positive and of influence in the teaching-learning process. We also observed that using the principles of the Pedagogy of Presence is not difficult to access. However, it is necessary for them to become aware that it is necessary to constantly review all the material that is taken to the classroom, that is, the content, as well as the speech, the discourse, and be proposed and open to constant formation and reflection of its pedagogical praxis.

We have used the dips in the ratio of excimer to monomer fluorescence intensity (E/M) as the index of lipid regular distribution to examine the effect of pressure on lipid lateral organization in the liquid-crystalline state of dimyristoylphosphatidylcholine (DMPC)/1-palmitoyl-2-(10-pyrenyl)decanoyl)-sn-glyceroI-3-phosphatidylcholine (Pyr-PC) bilayers. In the pressure range of 0.001-0.7 kbar at 30 °C, E/M dips remain discernible, suggesting that lipid regular distribution appears favorably in the liquid-crystalline state. In the same pressure range, E/M decreases steadily with increasing pressure at noncritical mole fractions; in contrast, E/M changes little with pressure at critical mole fractions. This result reveals an important physical principle underlying lipid regular distribution—that is, that membrane free volume reaches a local minimum at critical mole fractions of bulky lipids (for example, cholesterol and Pyr-PC). Using the activity of phospholipase A2 and the membrane fluidity inferred from diphenylhexatriene fluorescence polarization, we demonstrate that regular distribution of bulky lipids has a regulatory role in membrane properties or functions. Our data show that the activity of snake venom phospholipase A2 can be significantly modulated by minute changes (for example, 0.5 mol%) in the concentration of bulky lipids on either side of a critical mole fraction as a result of membrane free volume variation. The approach employed in this study illustrates the usefulness of high-pressure fluorescence methodology for obtaining new information about membranes at ambient conditions. High-pressure fluorescence spectroscopy has emerged as a powerful tool in biophysical research during the past 15 years (Paladini & Weber, 1981; Weber, 1992). Previous fluorescence studies of membranes at high pressure were focused on dynamic aspects, particularly on membrane fluidity. These dynamic studies have included probe rotations in lipid membranes (Chong & Weber, 1983; Chong et al., 1983; Mateo et al, 1993 and references cited therein), probe lateral diffusion (Flamm et al, 1982; Muller & Galla, 1983, 1987; Turley & Offen, 1985, 1986; Eisinger & Scarlata, 1987; Macdonald et al., 1988; Kao et al., 1992), spontaneous intermembrane transfer (Mantulin et al., 1984), and the relationship of membrane dynamics to the activity of membrane-bound proteins (Chong et al, 1985; Verjovski-Almeida et al, 1986; Jona & Martonosi, 1991).

This work intends to adopt fitness curves prediction from Genetic Algorithms (GAs) proposed in [Almeida et al. 2021], in the context of a more complex function, which is the Schwefel benchmark function. The prediction is performed with the knowledge only of the GA initialization parameters, using the Random Forest model. This approach addresses the main gap in the original work achieving good results, which makes this approach more promising.

In this paper the effect of truck traffic on road safety has been analyzed through simulation study. The main objective of the study is to quantify the effect of the decreasing average annual daily traffic of heavy duty vehicles (trucks) on road safety. As the road safety indicators the frequency road accidents is considered. The data used in the study were collected from one of the most crowded routes in Spain which connects Almeria (south-east) with Barcelona (northeast). The observed data covers year 2010 and were classified into 2 road types: dual carriageways and toll roads. The estimation was carried out using negative binomial model and Markov Chain Monte Carlo simulation. Using the estimation results new traffic scenarios were proposed where the traffic flow is assumed to change its values. A total of 33 scenarios were proposed and new accidents data were generated through MCMC sampling. The comparison of the simulated and observed accident data shows that the effect of decreasing truck traffic flow could meliorate road safety in the route. The simulation tool could be applied to evaluate the effects of freight modal shift from road to rail.DOI: http://dx.doi.org/10.4995/CIT2016.2016.4214

With deepening ocean development , a larger scale Internet of Underwater Things (IoUT) is being realized[1].More and more underwater equipment is being deployed, various ocean monitoring equipment, underwater robots and underwater group sites amongst others, all of which will be working in the deep sea for long periods of time in the foreseeable future[2].Due to the increasing working time and power consumption, it has become difficult for the high energy batteries carried by these facilities to cover their energy needs [3]. Therefore, it is necessary to solve the problem of electrical energy replenishment for underwater equipment.Based on Equinor’s Underwater Intervention Drone (UID) standard interface definition, Blue Logic have produced the world's first three universal, open-standard subsea drone docking stations.But this is not perfect, in the face of deeper waters, more complex multi-shape deep sea equipment charging needs, the current program is not enough to solve[4].Therefore, based on the IoUT scenario positioning, this research designs a subsea charging station that can serve multiple devices.The concept is similar to a land-based collection station for power banks, providing multiple sub-charging equipment that can be carried on the move to charge multiple subsea equipments of different types simultaneously.It also uses ocean energy to provide in-situ produced electricity for the underwater charging base station .Compared to Blue Logic's Subsea Drone Docking Station (SDS), it enables the multi-device charging needs of the IoUT using ultrasonic technology[5,6].In the long term, the combination of existing equipment will greatly reduce the cost of regional subsea long-term exploration and expand the scope of exploration[7].The paper will solve the following problems:1) How to solve the charging problem of long-distance survey of underwater equipments（e.g. AUV）?2) How to make the design applicable to charging usage scenarios common to different types, forms and sizes of underwater equipments?3) How to design underwater charging energy transmission more efficiently and sustainably?The research approach composed following parts:- Through literature research, sort out the development status of technical equipment such as underwater charging, underwater docking, underwater information transmission and marine power generation.- A structure interview with the opinions of deep-sea equipment designers and researchers to clarify the design requirements. - Analyze product features and problems and summarize the design process and direction through brainstorming method and solution building method.The design of the underwater multi-port charging base station solves the energy problem of deep-sea long-term survey equipment, with poor energy sustainability and low charging efficiency.This approach will enable true continuous subsea operations in extremely dynamic ocean environments.Although the project is still a conceptual design and various sensors are still being experimented with, it is forward-looking and instructive for future applications.References1.Wang X., Lu J., Peng W., &Song L.,(2021) Accelerating the construction of marine "new infrastructure" and promoting high-quality development of marine industry,Science & Technology Review,39(16),pp.76-80.2.Qu, Feng-Chong, Lai. , Liu, J.-Z., Tu, X.-B., Jiang, Y.,(2021)'Research and Application of Key Technologies for Marine Internet of Things', Telecommunications Science, 37, (7), pp. 25-33.3.Tian Y., Yuan R.,&Li X.,(2018)'Design and experiment of deep-sea microcurrent power generation system', Acta Energiae Solaris Sinica,Journal of China Academy of Electronics and Information Technology, 39, (4), pp. 873-878.4.SubseaDockingStation(SDS).[Online].Available:https://www.bluelogic.no/news-and-media/subsea-docking-station-sds-.5.Abicht, D., Torvestad, J.C., Solheimsnes, P.A., and Stenevik, K.A., ‘Underwater Intervention Drone Subsea Control System’, in Proceedings of the OTC, 2020.6.Wang Y., &Tian F.,(2019)'Research on acoustic wave-based charging planning in underwater sensing networks',Journal of China Academy of Electronics and Information Technology,14(11),pp.1183-11877.Cruz, N.A., Matos, A.C., Almeida, R.M., and Ferreira, B.M.: ‘A lightweight docking station for a hovering AUV’, in Proceedings of the IEEE, 2017, pp. 1-7.
