This paper explores the movement mechanisms of microswimmers in low Reynolds number environments by analyzing key physical concepts, microbial swimming mechanisms, and methods of calculating swimming speed. The study is based on three significant documents: “Life at Low Reynolds Number,” “The Hydrodynamics of Swimming Microorganisms,” and “A Mathematical Explanation of an Increase in Bacterial Swimming Speed with Viscosity in Linear-Polymer Solutions.” The main focus is on understanding how microorganisms adapt to their environment. Methods for calculating swimming speed were translated into MATLAB code to simulate the effect of angle on swimming speed, and a model confirming microbial movement was designed through SOLIDWORKS and 3D printing. Two experiments using the model were conducted in two different fluid environments. The result demonstrated the influence of different fluid viscosity on swimming velocity and stability. Computational simulations and experiments offered valuable insights into the swimming mechanisms of microorganisms in surroundings with low Reynolds numbers.

Against the background of the global emphasis on carbon emission reduction, the reform of the European Union's carbon emission trading system (EU ETS) will be incorporated into the shipping industry from 2024, which will have a significant impact on the operation of shipping enterprises. In this context, China's shipping enterprises urgently need to choose an appropriate carbon emissions trading model to effectively respond to the impact of the EU ETS, so as to accelerate the low-carbon transformation. Based on this, this paper constructs the Gounod competitive game model of two shipping companies under the baseline scenario and the cooperative strategy scenario, takes into full consideration the key factors of the shipping companies' market potential, cost, carbon emission quota and price in the model, and researches on the choice of carbon quota trading modes of the shipping companies under the EU ETS, such as purchasing emission allowances or cooperating with other companies to obtain allowances, etc. The equilibrium transportation of the shipping companies under different scenarios is also studied, and the impacts of different scenarios are also examined. The equilibrium volume, price and profit of shipping companies under different scenarios are solved, and MATLAB is applied to numerically analyze the decision-making variables of the model to further analyze the potential impact of EU ETS on the shipping industry. The results show that EU ETS policies always have a negative impact on traditional shipping companies, while sustainable shipping companies are affected.

With the rapid development of power electronics technology, DC-DC converters are increasingly applied in areas such as electric vehicles and renewable energy systems. This paper focuses on two common DC-DC converters—Buck (Step-Down Converter) and Boost (Step-Up Converter)—and elaborates on their operating principles. Through literature analysis and comparative studies, this paper explores the application of wide-bandgap semiconductor materials, strategies for suppressing electromagnetic interference (EMI), and optimization methods such as synchronous rectification and multiphase interleaving topologies. Additionally, the importance of these two converters is analyzed in practical applications like electric vehicle charging systems and solar power systems. The results show that adopting new materials such as gallium nitride (GaN) and silicon carbide (SiC) and intelligent control strategies can effectively improve converter efficiency, reduce losses, and address technical challenges in high-frequency operation. This research provides theoretical and practical references for the design and application of high-performance DC-DC converters, contributing significantly to technological advancements in the renewable energy field.

When renewable energy are connected to the power grid through power electronic technological (such as inverters), ensuring the stability of the power grid becomes a very valuable challenge. This is because power electronic converters usually encounter some problems when converting electrical energy, such as unstable voltage, the presence of high-frequency or low-frequency harmonics, islanding effect, leakage current, etc. To solve these problems and enhance the stability of power grids when new energy is connected, improvements can be made to the components and topological structure of power electronic modules, or more precise and comprehensive control strategies can be adopted. This paper outlines the topological structures and control strategies of inverters in photovoltaic grid-connected systems, including innovative topological structures, control algorithms, and analysis methods.

With the increase in the proportion of wind energy in the power system, its intermittentity and volatility pose a challenge to the stable operation of the power system. Accurate wind forecasts are crucial. This paper proposes a wind energy prediction method for backpropagation (BP) neural networks which rely on the particle swarm optimization (PSO) algorithm improved. First, the year-on-year operational data of the wind farm, including multi-dimensional information, such as wind speed and direction, were standardized for pre-processing. The processed data are then inputted to the BP neural network model which is founded on the trained PSO and the initial weight and threshold are optimized by PSO. Case studies show that this method performs best in root square error, average absolute percentage error and accuracy compared to traditional methods such as BP neural network, support vector apparatus, and chronological series analysis, achieving more accurate and stable wind energy prediction.
