    Reliability analysis of single-story industrial buildings under wind load based on Monte Carlo simulation

    Uncertain disasters such as typhoons can affect buildings. Single-storey industrial building is an important type of factory building. In this paper, the reliability of a single storey industrial building under wind load is studied by taking one typical factory in Hunan, China as an example. Firstly, finite element method is used to analyse the structure in the range of linear elasticity. Then, based on Monte Carlo simulation, the probability of failure of the structure under wind load is obtained. The results show that the probability of damage is relatively small, which is also in line with the fact that inland areas are not easily affected by typhoons. In order to obtain a deeper understanding of its reliability, the structural fragility curve considering the variability of steel strength is also studied. The results showed that the smaller the variability of the steel, the more beneficial it is for the reliability of the structure.

    Sustainable aviation fuel as a pathway to mitigate global warming in the aviation industry

    The extensive utilization of fossil fuels by humanity has led to notable ecological degradation alongside a surge in productivity. The ensuing climate change, a result of global warming, poses a grave threat to human survival. A significant contributor to global warming is the emission of abundant greenhouse gases, with carbon dioxide being the most prevalent. Addressing global warming necessitates the identification and adoption of cleaner, alternative fuels to diminish carbon dioxide emissions. Sustainable Aviation Fuel (SAF) emerges as a prime alternative in this context. Chemically akin to conventional and fossil fuels, SAF originates from cleaner sources, offering a reduction in carbon dioxide emissions upon combustion. This paper highlights the importance of SAF as a viable strategy to mitigate CO2 emissions resulting from fossil fuel combustion. The paper also examines different SAF synthesis approaches, such as Fischer-Tropsch, Hydrogenated fatty acid esters and fatty acids (HEFA), and Alcohol-to-Jet (ATJ) processes. In summary, challenges such as high production costs, raw material price fluctuations, and the need for supportive policies hinder SAF's widespread adoption. To address climate change and reduce aviation emissions, further research, technological advancements, government incentives, and collaborative efforts within the aviation industry are crucial.

    Bitcoin price forecasting using ARIMA model

    The Bitcoin price was chosen as the research subject, and the observation period was set from January 2015 to September 2023. An ARIMA time series model was constructed to forecast the trading price. The results indicate that the optimal model for fitting the trading price is ARIMA (3, 2, 8). This model takes into account trends, seasonality, and other factors that may impact the price of Bitcoin. By analyzing the historical data, the model was able to accurately predict the short-term fluctuations in Bitcoin’s trading price. Based on this, short-term predictions were made for Bitcoin’s trading price in the next year. Recommendations were then provided by combining the forecast results with the economic development situation in the post-pandemic era. The recommendations suggest that Bitcoin has become a low-quality asset and is no longer suitable for diversifying one’s investment portfolio, but rather focus on the development of physical industries and adjust one’s investment portfolio in a timely manner.

    Comparison of diesel engine with other engines and NOx scandal

    This essay will focus on the comparison of the Homogenous Charged Compression Ignition engine and the Diesel engine. Diesel engine is one of the most widely used engines in the world. It uses fossil fuel such as the gasoline to get power. What is more, it does not need a spark to ignite the fuel. It uses compression method to burn the fuel. However, there is also some problems for this kind of engine, such as the greenhouse effect and the heat loss for this kind of engine. Compared to the Diesel engine, the Homogenous Charged Compression Ignition engine can mix the fuel into a correct ratio before burning. This can improve the efficiency of burning process. It can also improve the energy it released to get more power. There are several solutions to the problem. For example, to reduce the bad effect caused by the fossil fuel, people started to develop the hydrogen fuel. There are also some limitations of the hydrogen, such as expensive cost for producing the hydrogen and the hard storage of hydrogen. Use hydrogen to replace the fuel will face some problems. As a result, improving the efficiency of burning fossil fuel will also be a good choice. The essay also focuses on the scandal of diesel engines, mainly talks about the scandal of the diesel-engine transportation. Diesel engines are the most widely used engine in the world, they will release wastes, pollution and some toxic gases when they are working. Have these scandals been fixed?
