The study aims to evaluate the behavior of these designs in low-speed collisions by utilizing aluminum and steel as two different materials. Four primary forms of thin-walled structures, including concentric circles, tangent circles, half-balanced circles, and spiral circles, were thoroughly examined using finite element analysis. Mesh-independent tests were conducted to ensure the accuracy of the simulation results, and various crumple displacements were compared to determine the optimal mesh sizing. The numerical results demonstrate a significant reduction in peak force for the aluminum crash box, with a remarkable 60% decrease compared to the steel crash box. Furthermore, the spiral shape, identified as an optimized design, exhibits a low peak force of only 118.42 kN and offers superior energy absorption of 9.15 kJ per kilogram compared to the other designs. Consequently, employing nature-inspired designs provides substantial benefits for enhancing crashworthiness in energy-absorbing devices.","PeriodicalId":12085,"journal":{"name":"Evergreen","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135691586","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aims to obtain an LNG delivery model from the Ambon Hub to all gas power plants in the Maluku and Papua regions. There are currently about 33 prioritized Mini Gas Power Plants (PLTMG) in eastern Indonesia as proof of the Indonesian government's commitment to lowering carbon emissions. With a market share of 14.09 % of the total domestic gas demand, the electricity industry is one of the primary consumers of domestic gas demand. Mission analysis was carried out on a type C tanker as a gas storage system because of its advantages. This analysis studies the primary transportation demand for LNG to create the best LNG supply chain scenario for eastern Indonesia. Supply and demand analysis is also carried out to obtain the optimum ship size. In addition, planning and optimization of shipping routes have also been carried out, considering the limited time for LNG storage. Several Vehicle Routing Problem (VRP) analysis methods found that the Heuristic method is more effective than other methods, with an efficient delivery time of 2-3 days, which is better effective with the choice of a predetermined operational.","PeriodicalId":12085,"journal":{"name":"Evergreen","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135691602","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The primary metric that affects the PV system's productivity, dependability, profitability, ecological footprint, and grid compatibility are called Key Performance Indicators (KPIs). This study analyzes the KPIs of a 93.6 kW grid-connected rooftop PV system in South Tangerang and then compares them with the previous studies. Solar irradiation and output power data are collected. Then a modified extrapolation approach is used to fill in data gaps before proceeding with the performance parameter calculation. The performance indicator analysis refers to the IEC 61724-1 standard, including performance ratio (PR), final energy yield, system efficiency, system losses, and capacity factor. The results indicate that the PR, final energy yield, system efficiency, losses ratio, and average daily capacity factor varied from 82.0% to 91.6%, 2.94 to 3.70, 13.7% to 15.7%, 8.4% to 18.0%, and 12.12% to 15.67%, respectively. Compared to other studies, the PR values are much higher than expected. All of the other parameters, however, are normal. As a result, it shows that the PV system is working correctly.","PeriodicalId":12085,"journal":{"name":"Evergreen","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135691604","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Optimization of Power Flow using GA Fuzzy Approach","authors":"Sanjeev Kumar, None Prateek Kumar Singhal, Vineet Kumar, None Laxmi Kant Sagar","doi":"10.5109/7151702","DOIUrl":"https://doi.org/10.5109/7151702","url":null,"abstract":": The optimal power flow (OPF) issue is a critical optimization job in the operation and planning of power systems. It entails establishing the best settings of control variables to minimize generating costs while meeting operational restrictions. Traditional optimization techniques often struggle to handle the complexities and uncertainties inherent in power systems. This paper introduces fuzzy systems' concepts and their integration with genetic algorithms. It then delves into the many possibilities for power system optimization problems. The first section introduces the fundamental ideas of fuzzy, while the second section explores its structure and components. The third section explores the genetic algorithm's synergism with the fuzzy technique. The suggested technique was evaluated on an upgraded IEEE 30-bus system, with an optimal solution indicating fuel cost reduction under various linear and non-linear constraints. The suggested methodology's results were compared to all those mentioned in the literature. The outcomes of the offered methodologies are encouraging, demonstrating the efficacy and resilience of the proposed procedures. The synergism of the fuzzy system with the genetic algorithm offers several advantages, including flexibility in handling uncertainties, adaptability to complex systems, and the potential for discovering innovative solutions. However, it is important to carefully design the fuzzy system's rule base and appropriately set the genetic algorithm's parameters for optimal performance.","PeriodicalId":12085,"journal":{"name":"Evergreen","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135690294","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
