Applying an Ordinary Least Squares (OLS) Regression Model On Processed Air Quality and Environment Data (Published)

This scientific research is primarily based on real-time data collected on air quality. A comprehensive and extensive study was initially conducted to explore the key factors contributing to air pollution. Other relevant information will encompass additional components such as PM10, PM1, and weather-related factors like temperature, humidity, and air pressure. In order to provide a more reliable but at the same time qualitative information it was essential to examine the anomalies and issues revealed by the gathered data. After carefully identifying and correcting anomalies in the dataset, various statistical analyses have been conducted and results have been presented in both tabular and visual formats. These data are based on fundamental inquiries directly tied to the significance of air quality. After interpreting the statistics, a regression model such as OSL was used always including data that do not have multicollinearity. Based on the findings, it appears that this model is not suitable for forecasting PM2.5 levels because of a significant association between PM10 and PM1

Implementation of Eulerian Paths based on the model of the Chinese postman: Application to the problems of garbage collection in the streets of the City of Kananga (Published)

Graph theory today plays a very important role in modeling and solving many problems. The complexity of this subject is considerable, especially since we must speak at the same time of the Chinese postman and the Eulerian journey. If it remains true that the concern is the search for the path which minimizes the cost, we understand that it will be imperative for us to glean from Fleury’s algorithm, without failing to lead to the possible conditions for the realization of Euler’s dreams. On the city of Kananga, whose road network is more than complex in the tangle of its arteries? In this article we seek to see how we can solve the problem of garbage collection by going through each intersection once and only once, thus minimizing cost and time.
