Abstract: |
This study investigates the interpolation system parameter-free conical radial basis function algorithm. The effective condition number (ECN) is considered. The main difference between ECN and the traditional condition numbers is in that the ECN takes into account the right-hand side vector to estimates system stability. Even the ECN is a superior criterion over the traditional condition number for some numerical methods, it is not obvious for the conical radial basis function algorithm. Numerical results show that the ECN is not roughly inversely proportional to the numerical accuracy. |

Abstract: |
Liuchuan Canal in Taichung City is a key water environment area. The “Endless Flow” research project aims to enhance water quality and highlight the watershed’s historical and cultural aspects through the core concepts of safety, environment, and culture. The project established the “Endless Liuchuan Canal” digital tour platform, integrating local water environment information with engineering guides and mobile applications. It uses data analysis to assess effectiveness and attracts public engagement through gamified knowledge, intelligent services, and multifunctional robots. By May 2024, the platform had over 410,000 users. The project reached 2.55 million people through integrated marketing, including a launch event and parent-child activities, which garnered significant media attention. A May 2024 event saw high participation and satisfaction, promoting intergenerational learning through guided tours and AR games. |

Abstract: |
High-voltage pulsed power generators play a crucial role in various challenging applications, such as military, medical, and industrial sectors, where quick energy transfer and high efficiency are essential. Conventional power generation systems, particularly the commonly utilized Marx generator, frequently encounter considerable constraints because of intrinsic inductive and resistive losses. Such losses may result in inefficiencies and longer rise times, limiting their effective use in high-performance settings. In this research, we introduce a capacitor-diode voltage multiplier (CDVM) circuit as a groundbreaking substitute for conventional Marx generators. The design features a spark gap switch optimally positioned to reduce series inductance and resistance, enabling quicker charging capabilities and significantly enhanced energy transfer efficiency. In order to comprehensively evaluate its performance, we modeled the CDVM circuit in MATLAB and performed a comparative study with traditional and bipolar Marx generators under the same operating conditions. Critical performance indicators—such as peak voltage, rise time, and energy transfer efficiency—were examined, revealing that the CDVM provides significant enhancements. This groundbreaking design offers a flexible and extremely effective solution, expanding the range of high-voltage pulsed power systems and delivering improved adaptability for various, high-demand applications. |

Abstract: |
With the growing population and developing economy, the demand for energy is increasing both in the world and in Türkiye. If there is no change in current energy policies, non-OECD countries will be responsible for 87% of global energy demand by 2030. In this case, the fight against climate change also shows a dangerous trend. By 2050, the upper temperature increase limit of st üst indis will be exceeded if an internationally binding agreement on restricting the emission of other greenhouse gases, especially 20 degree emissions, cannot be established. Therefore, renewable energy sources are of strategic importance in the implementation of climate change policies in cities. Therefore, with today's developing technology and increasing energy demand, renewable energy resources should be used efficiently. The fact that fossil energy resources are both environmentally damaging and uneconomical has made these resources dispensable. One of the renewable energy sources that is environmentally friendly is wind energy. In order for wind energy to compete with alternative energy sources, various incentive policies are implemented by governments. These incentives make a great contribution to sustainable development in order to develop wind energy and expand its availability. In this context, energy efficiency is an important issue that should be examined as a priority in terms of sustainable development and should be investigated in terms of current situation and development potential. In this study, the availability and potential of wind energy in Bitlis province is examined. Then, the wind energy potentials of Bitlis province and its districts were evaluated by mentioning Türkiye's Renewable Energy Resources potential. The necessary data for the evaluation were obtained from Bitlis Province Meteorology Directorate. During the evaluation process, hourly wind speeds for January, March and August were taken in each district of Bitlis province. In the evaluation, it was seen that the wind speed was above 7 m/sec in 8 hours of 24 hours on average in the data taken only from Tatvan Nemrut Ski Center and a sample feasibility study was made for the wind power plant that could be established here. |

Abstract: |
This study aims to increase the population and productivity of native chickens through the production of ready-made feed as a source of animal protein for native chickens. The target to be achieved is to increase the knowledge and skills of farmers in producing ready-made feed (pellets) for native chickens and ensure the availability of feed for native chickens both in terms of quality and quantity. The activities to be carried out are the manufacture of a chicken feed mixer machine with a capacity of 120 kg/hour and an intensive introduction program for raising native chickens; introduction of feed ingredients for native chicken rations; introduction of native chicken ration formulations; and training in making ready-made feed (pellets). The method used in empowering the target partner group (native chicken farmer community is a learning technique in the form of providing theory, simulations to the community who are target partners and then direct practice with students and target partners. |

Abstract: |
Currently, technology plays a significant role in distance education, enhancing productivity and efficiency in the teaching-learning process. As a result of the COVID-19 pandemic, a proposal was developed to create a practical manual aimed at fostering the development of competencies for the course "Standardized Work from Home." This was the objective of the study. The methodological route of the PDCA cycle (Plan, Do, Check, Act) was employed to define the sequence of activities and used the Institution's reference guide. The manual includes playful activities that can be conducted in various settings, not just in the Industrial Engineering lab, focusing on topics such as capacity and efficiency calculations, time-taking techniques, process analysis, 5S systems, continuous flow, among others. These topics are particularly useful for achieving quality and productivity in processes. In conclusion, the design of remote practices was successfully achieved, allowing the course to continue, maintaining students' academic progress, and contributing to competency achievement. It is recommended to continue developing these types of resources, which, although born out of necessity during the pandemic, have proven highly beneficial for education. |
