A large part of our daily lives is spent with audio information. Massive obstacles are frequently presented by the colossal amounts of acoustic information and the incredibly quick processing times. This results in the need for applications and methodologies that are capable of automatically analyzing these contents. These technologies can be applied in automatic contentanalysis and emergency response systems. Breaks in manual communication usually occur in emergencies leading to accidents and equipment damage. The audio signal does a good job by sending a signal underground, which warrants action from an emergency management team at the surface. This paper, therefore, seeks to design and simulate an audio signal alerting and automatic control system using Unity Pro XL to substitute manual communication of emergencies and manual control of equipment. Sound data were trained using the neural network technique of machine learning. The metrics used are Fast Fourier transform magnitude, zero crossing rate, root mean square, and percentage error. Sounds were detected with an error of approximately 17%; thus, the system can detect sounds with an accuracy of 83%. With more data training, the system can detect sounds with minimal or no error. The paper, therefore, has critical policy implications about communication, safety, and health for underground mine.
我们日常生活的很大一部分都是与音频信息一起度过的。大量的声学信息和令人难以置信的快速处理时间经常出现巨大的障碍。这就需要能够自动分析这些内容的应用程序和方法。这些技术可以应用于自动内容分析和应急响应系统。人工通信中断通常发生在紧急情况下，导致事故和设备损坏。音频信号很好地向地下发送了信号，这就需要地面应急管理小组采取行动。因此，本文试图利用Unity Pro XL设计并仿真一个音频信号报警和自动控制系统，以替代紧急情况的人工通信和设备的人工控制。使用机器学习的神经网络技术对声音数据进行训练。使用的指标是快速傅里叶变换幅度，零交叉率，均方根和百分比误差。声音检测的误差约为17%;因此，该系统可以以83%的准确率检测声音。通过更多的数据训练，系统可以以最小的错误或没有错误检测声音。因此，本文对地下矿山的通信、安全和健康具有重要的政策意义。

In this study, we thoroughly examined the impact of heat treatments and hole count (p) on the properties of LnSrBaCu3O6+z (Ln = Eu, Sm, Nd) compounds. We focused on preparation, X-ray diffraction with Rietveld refinement, AC susceptibility, DC resistivity measurements, and heat treatment effects. Two heat treatment types were applied: oxygen annealing [O] and argon annealing followed by oxygen annealing [AO]. As the rare earth Ln’s ionic radius increased, certain parameters notably changed. Specifically, c parameter, surface area S, and volume V increased, while critical temperature Tc and holes (p) in the CuO2 plane decreased. The evolution of these parameters with rare earth Ln’s ionic radius in [AO] heat treatment is linear. Regardless of the treatment, the structure is orthorhombic for Ln = Eu, tetragonal for Ln = Nd, orthorhombic for Ln = Sm [AO], and pseudo-tetragonal for Sm [O]. The highest critical temperature is reached with Ln = Eu (Tc [AO] = 87.1 K). Notably, for each sample, Tc [AO] surpasses Tc [O]. Observed data stems from factors including rare earth ionic size, improved cationic and oxygen chain order, holes count p in Cu(2)O2 planes, and in-phase purity of [AO] samples. Our research strives to clearly demonstrate that the density of holes (p) within the copper plane stands as a determinant impacting the structural, electrical, and superconducting properties of these samples. Meanwhile, the other aforementioned parameters contribute to shaping this density (p).

In the vast majority of mobile applications, the Transmission Control Protocol (TCP) is still leveraged at the transport layer of the Internet’s protocol stack. But, in many cases, the performance of TCP over mobile networks has been proven sub-optimal in practice, thus causing substantial bottlenecks. Quick UDP Internet Connections (QUIC) is a new protocol, currently being standardized by the Internet Engineering Task Force (IETF), that aims at solving some of the inherent problems of TCP. The purpose of this paper is to provide a comprehensive overview of QUIC and compare the performance of QUIC and TCP in wireless networks. To compare QUIC with TCP under various transmission scenarios over LTE networks, the ns-3 network simulator has been employed. The simulations performed showed that 1) under good or average transmission conditions, QUIC is characterized by a better steady state throughput at the same time achieving quite lower file download times; and 2) under poor transmission conditions, the two protocols exhibit a similar performance.
