This work supports the problematization of the high rate of traffic accidents due to the increased use of automobiles for utility or transport in Brazil. Every year, the lives of approximately 1.3 million people are interrupted due to traffic accidents worldwide. In this regard, this study proposes the use of data mining as an approach to analyze and explore datasets of traffic accidents that occurred on Brazilian highways between the years 2017 and 2022, as provided by the Federal Highway Police. Additionally, vehicle price data were included, allowing for a more comprehensive analysis that also considers the financial value of the vehicles. The goal is to assess the predictive capability of classification models regarding the severity of accidents, focusing on vehicle characteristics and environmental factors. By applying classification algorithms and machine learning explainability techniques, we acquired relevant knowledge regarding the studied data, contributing to understanding and preventing accidents. As a result, the attributes related to vehicle characteristics had a more positive impact on the predictive capability of the models when compared to the attributes describing the environment and other variables.
The accuracy and stability of brain tumor MRI image classification is significant for the healthcare system, but the traditional models have the defects of difficulty in handling complex features and unstable classifi...

Weather parameters and weather forecasting play a crucial role in scientific experiments for the safe operation of the system. Weather prediction involves high-performance computing, which enables building of weather models. Major Atmospheric Cherenkov Experiment (MACE) is a 21m ground-based, very high-energy gamma-ray telescope installed at Hanle, India. Accurate and reliable short-term weather prediction plays a crucial role in ensuring the safe and efficient functioning of the telescope. In the first part of the paper, we describe the multithreaded design of the real-time weather data capture application for the telescope. In the second part, we compare the performance of time series algorithms for weather prediction and the possibility of hybrid models for predicting non-stationary weather factors.

As the scale and complexity of data centers continue to increase, intelligent operation and maintenance (O&M) has become one of the important technologies to ensure high performance and availability. Among them, Key Performance Indicator (KPI) data reflects the health status of data center systems and plays a key role in intelligent O&M. Accurate KPI time series prediction is essential for detecting KPI anomalies and improving the reliability of data center systems. However, traditional time series prediction models have low accuracy when dealing with KPI data. Therefore, this paper proposes a time series prediction model based on contrastive learning and frequency domain attention mechanism to more fully capture the temporal features of KPI data, improve prediction accuracy and reliability. The experimental results show that the proposed model exhibits strong competitiveness in KPI time series prediction.

Financial institutions are subject to stringent regulatory reporting requirements tomanage operational risk in international financialmarkets. Producing accurate and timely reports has raised challenges in current data processes of big data heterogeneity, system interoperability and enterprise-wide management. data quality management is a key concern, with current approaches being timeconsuming, expensive, and risky. This research proposes to design, develop, and evaluate a Financial Reporting data Quality Framework that allows non-IT data consumers to contextualize data observations. The framework will use anomaly algorithms to detect and categorize observations as genuine business activities or data quality issues. To ensure sustainability and ongoing relevance, the framework will also embed an update mechanism.
