Solar panel systems are widely used to meet energy needs at this time. Solar panels have optimal power for 4 hours, namely 10:00 to 14:00. but this is still said to be not optimal if the angle of the static solar panels does not follow the movement of the sun. This can also be caused by weather factors that are covered in clouds. Previous research conducted by Tri Wahyu Ardianto used mirror reflectors but was not equipped with sensors and data storage. Based on this, to optimize solar panel energy, a flat mirror reflector design for solar panels has been made, equipped with four flat mirror reflectors on each side to form a large square. The solar panel is placed in the middle between the four flat mirrors. In this study, the measurement of electric power was carried out by carrying 3 variable angles for reflector positions, namely 0°, 60°, and 70°. The decision of the three reflector positions is made to find out the ratio of the maximum output power values. This system is also equipped with current, voltage, and light intensity sensors. The results show that the maximum output power of solar panels is shown at the reflector position of 60° with an average power output of 19.70 Watt followed by a reflector position of 70° with an average output power of 19.18 Watt and finally the reflector position is 0° with an average output power value of 14.87 Watt.

Junk goods are no longer piles of worthless goods for businessmen who are keen to see the economic value by taking this opportunity by becoming a pelapak company to buy and sell junk goods purchased from collectors to be sold to buyers. The problems found with Pelapak include the manual recording of sales administration which has the potential to cause recording errors. Pelapak does not know for sure the stock of junk they own and those owned by collectors because the locations of the collectors are far apart. Orders of junk goods between pelapak and collectors are still via telephone so pelapak does not know which collectors are in the process of sending goods. Problems also occur on the part of collectors including unprofessional sales transactions. Based on these problems, a used goods stock management system is needed using the Economic Order Quantity (EOQ) method. The purpose of this study is to build a used goods stock management information system that can monitor the availability of used goods owned by collectors and pelapak. System development uses the prototype method and designs with concepts. The results of the research are that the system created can help find out the stock and the amount in each collector, recap sales reports, provide accurate information, facilitate business transactions and fulfill sales targets to buyers.

Multi-Channel Phase-Shifted Resonant Converter for Fuel Cell Application and Effect of Constant Power on its Characteristics
Authors: Zaikin Denys , Andersen Martin Kolding , Rugholt Mark , Kjeldsen Thomas
Published: August 2023

This paper presents a multi-channel phase-shift LLC resonant converter that was specially optimized for fuel-cell applications and has a wide input and output voltage range. The worst-case minimum stack voltage and the battery voltage range were used to find the optimal parameters of the LLC converter. The voltage gain of the converter operating at a constant power was considered, and the algorithm for such a calculation was proposed. Current balancing was implemented using channel temperature measurements instead of expensive current measurements. A natural self-balancing mechanism was investigated for converters operating at high frequencies above the series resonance of a resonant converter. Recommendations for the converter’s transformer turn ratio were illustrated for efficiency optimization. The multi-object optimization is implemented to reach the optimized design so the minimum and maximum voltage gains can be reached and, at the same time, the transformer turn ratio is kept at the minimum to reach high efficiency. An experimental prototype of a four-channel converter was presented and tested at a 5 kW power level. Active content and C-language code files for converter calculations are provided as well with this work.

Para a pesquisa, utilizar-se-á o método lógico-dedutivo e pretende-se demonstrar que a adoção do sistema de precedentes pelo ordenamento jurídico brasileiro tem contribuído de forma significativa para o fortalecimento da democracia contemporânea. Em especial na dimensão da democracia constitucional, notadamente no respeito aos direitos fundamentais, representados pela segurança jurídica, estabilização da jurisprudência, prestígio à igualdade e confiança no sistema de justiça.  Neste caso, o protagonismo advém do Poder Judiciário e, no seu topo, do Supremo Tribunal Federal, e consiste na estrita observância ao devido processo legal, ao contraditório substancial e à construção democrática dos precedentes qualificados, que passaram a compor o ordenamento jurídico como fonte primária do direito.

Com a pretensão de restabelecer a relação entre paz, direitos humanos e democracia, o presente estudo tem o intento de realizar uma reflexão acerca da construção, desconstrução e a necessidade de reforços de paradigmas a nível nacional e transnacional a fim de possibilitar relações mais sustentáveis. Revestido dos métodos de procedimento dedutivo e histórico, trata-se de uma pesquisa bibliográfica de abordagem descritiva, a partir de autores clássicos e contemporâneos. O reconhecimento e a proteção dos direitos do homem estão na base das Constituições democráticas modernas. A paz, por sua vez, é o pressuposto necessário para o reconhecimento e a efetiva proteção dos direitos do homem em cada Estado e no sistema internacional. Ao mesmo tempo, o processo de democratização do sistema internacional, que é o caminho obrigatório para a busca do ideal da “paz perpétua”, no sentido kantiano da expressão, não pode avançar sem uma gradativa ampliação do reconhecimento e da proteção dos direitos do homem, acima de cada Estado. Diante disso, se faz urgente a reconstrução de espaços nacionais e transnacionais que se pautem por uma revalorização da política e da democracia, dos direitos humanos fundamentais, da paz e da solidariedade, como diretrizes básicas para uma convivência sustentável, com justiça social, harmonia e paz.

A Pandemia da COVID-19 trouxe para o cenário mundial diversos desafios que emanaram diferentes posicionamentos na condução para contenção dos avanços da doença. O objetivo desta pesquisa foi o de analisar a interferência da política nos mecanismos de combate da Covid-19 no Brasil com destaque para o uso indiscriminado de Hidroxicloroquina sólida e o descumprimento dos princípios bioéticos. A metodologia utilizada foi a do método dedutivo; quanto aos meios a pesquisa foi bibliográfica e quantos aos fins, qualitativa. A conclusão a que se chegou foi a de que há, a nível nacional e mundial, um ambiente cientifico, com instituições competentes na área da saúde, investindo esforços para estudar meios de conter o avanço da pandemia e proteger a humanidade do caos e, em outro contraponto, a exposição de segmentos políticos e seus líderes no Brasil agindo com atitudes contrárias as normas e recomendações estabelecidas. O uso da Nebulização da Hidroxicloroquina no Amazonas, mais precisamente na capital, Manaus, respalda o comportamento negacionista da ciência coordenado por esse movimento nominado de “Bolsonarismo”.
