The problem of energy depletion has brought wind under consideration to replace oil- or chemical-based energy. However, the breakdown turbines is a major concern. Accordingly, unsupervised learning was performed using vibration signal power generator achieve an outlier detection performance 97%. We analyzed data through wavelet packet conversion and identified specific frequency band that showed large difference between normal abnormal data. To emphasize these bands, high-pass filters were applied maximize difference. Subsequently, dimensions reduced principal component analysis, giving unique characteristics preprocessing process. Normal collected from farm located in northern Sweden first preprocessed trained long short-term memory (LSTM) autoencoder perform detection. LSTM Autoencoder model specialized for time-series learns patterns detects other as outliers. Therefore, we propose method learning, utilizing signals generators. This will facilitate quick accurate failures provide alternatives depletion.

Development of a Quantitative Assessment Algorithm for Operational Risks in Mining Engineering

Resources, Год журнала: 2025, Номер 14(4), С. 53 - 53

Опубликована: Март 25, 2025

Whenever any type of ore deposit is developed, it comes with significant risks, such as uncertain reserves, harsh climate conditions, and other uncontrollable factors. To manage these risks effectively, companies need to quickly adapt changing conditions. This paper presents a method for evaluating using simulation model. The main objective identify factors operational risk determine the project parameters that have greatest impact on probability event. includes classification based way they arise; creation decomposition matrix dividing by production tasks; construction mathematical model identified was tested developing an underground mine conveyor network in Anylogic (8.9.2) software. A experiment showed shutdowns could result 11.23% reduction annual revenue. Based results, recommendations were made how can be reduced implement transport system increase resilience.

Comprehensive Assessment of the Effectiveness of Passenger Transportation Processes using Intelligent Technologies

The Open Transportation Journal, Год журнала: 2024, Номер 18(1)

Опубликована: Июнь 21, 2024

Introduction This studypresents a comprehensive evaluation of the effectiveness passenger transportation using intelligent technologies based on economic, technical, and operational efficiency parameters. It reviews existing approaches to assessment proposes an optimal set criteria for assessing transport process, which will allow better planning routes, movement schedules, choice rolling stock. Objective study aims provide technologies. Aims article carry out integral economic technical-operational efficiency, routes schedules selection stock Methods In order obtain criterion diverse techniques, including computer mathematical modeling, algorithm theory, statistics, observation, measurement, were employed. Results A general was created in evaluate processes overall costs both user operator. Furthermore, specific has been defined: passenger-kilometers traveled. The applicability model is evaluated bus corridor Havana. results show that due external factors, namely overcrowding, decrease at same rate 12-meter 15-meter buses with different intervals, while number passengers transported per kilometer increases faster larger buses. Conclusion Choosing assess process requires considering various aspects importance result comfort safety, as well process. To solve this problem, it necessary do additional research analyses determine most appropriate under conditions. particular, consider vehicles smaller capacity take into account volumes variable demand.
