Theoretical and Natural Science

- The Open Access Proceedings Series for Conferences

welcome Image

The proceedings series Theoretical and Natural Science (TNS) is an international peer-reviewed open access series which publishes conference proceedings from a wide variety of disciplinary perspectives concerning theoretical studies and natural science issues. The series publishes articles that are research-oriented and welcomes theoretical articles concerning micro and macro-scale phenomena. Proceedings that are suitable for publication in the TNS cover domains on various perspectives of mathematics, physics, chemistry, biology, agricultural science, and medical science. The series aims to provide a high-level platform where academic achievements of great importance can be disseminated and shared.

    With rapid urbanization, urban water supply pipeline accidents have become increasingly prevalent. Understanding their common occurrences and prevention strategies is crucial for ensuring water safety. This study aims to explore the underlying causes of such incidents, ranging from ageing infrastructure to design flaws and construction issues. By analyzing existing preventive measures and international best practices, this research seeks to contribute to the development of effective strategies for mitigating urban water supply pipeline accidents. This thesis focuses on urban water supply pipeline accidents, addressing both common incidents and preventive measures. It begins by highlighting the unique challenges of fires in high-rise buildings, including their rapid spread and the difficulties in evacuating occupants. The paper then emphasizes the importance of innovative fire-resistant materials, classifying them into various types such as phenolic, sprayed, calcium silicate, and lightweight composite materials. Each type is explored in detail, discussing their properties and potential applications. Finally, the paper outlines the practical use of these materials in fire engineering, emphasizing their role in enhancing the safety and resilience of urban infrastructure. Overall, this thesis contributes valuable insights to understanding and mitigating the risks associated with urban water supply pipeline accidents, promoting disaster prevention and management efforts.

    Quantum communication plays a key role in the next generation of information transfer and security schemes, by using quantum entanglement and measurements from quantum mechanics. We introduce the mathematical and physical foundations of quantum communication, such as the CNOT gate and Kronecker product. Then we propose two quantum communication protocols, namely dense coding and stealth coding. These protocols offer unique advantages that are theoretically unbreakable. Then we extend the protocols to the quantum communication protocol allowing for third-party supervision to ensure information security. Based on this, a communication protocol involving four parties is designed, enabling them to exchange information while being supervised.

    Volcanic eruptions are one of the natural phenomena on Earth that have the capacity to affect the global climate, local ecosystems and human societies. Among the various ejecta, volcanic ash is particularly noteworthy because of its multifaceted impacts on the environment and human beings. This paper focuses on the impacts of volcanic ash on climate, water quality, soil and plants, wildlife, and human health using the research methodology of a literature review, and also discusses preventive and curative measures against volcanic ash as well as the application of volcanic ash in order to minimize the adverse consequences. Through comprehensive analysis and synthesis of relevant literature, the impacts of volcanic ash on various fields and coping strategies are summarized in this paper, aiming to provide references for research and practical endeavors related to volcanic ash.

    As the stock market plays a crucial role in the world economy, researchers have used multiple mathematical and statistical models such as Artificial Neural Networks (ANN) and Long Short-Term Memory (LSTM) networks model to forecast the fluctuation in stock price despite their unpredictability as the stock market, being a stochastic process, would be easily affected by an abundance of factors such as governmental policies, industrial news, and natural calamities. Therefore, based on the previous studies, this paper attempts to forecast the stock opening price of Apple Inc., one of the world-leading companies in the technology industry, utilizing the Autoregressive Integrated Moving Average (ARIMA) model. In order to minimize the impact on the stock market brought by the COVID-19 pandemic, this paper will analyze separately the opening price of Apple stock before and after the epidemic outbreak and will compare the difference the pandemic made in the stock market, as well as the forecasting models.
