Artificial Neural Networks (ANNs) are crucial for modeling complex systems, making predictions, and optimizing processes across various domains. Inspired by the human brain structure, ANNs consist of interconnected neurons organized in layers. They excel at identifying patterns and relationships in data, approximating arbitrary functions, and predicting sequences. ANNs are useful in wastewater treatment, water resource management, climate change studies, and healthcare. They can optimize and control processes, outperforming traditional linear and non-linear models in phenolic contaminants removal. ANNs are effective in handling large datasets and making quick predictions. They can be used in river flow forecasting and can be combined with other techniques for pressure reconstruction. Most used ANNs include Fully Connected Neural Networks (FCNNs), Feed Forward Neural Networks (FNNs), and Back Propagation Neural Networks (BPNN). However, due to shortcomings in existing ANN variants, new ...

The history of transportation is largely the history of material progress. It is difficult to imagine a prosperous society without the knowledge of the arts and sciences for commerce. The natural arrangement of land and water is not the most convenient for commerce and travel, as oceans and seas have unsuitable routes, and rivers are often rocky and shallow. Knowledge of roads, bridges, and canals has been acquired and slowly applied, but the aboriginal inhabitants of a country usually cared for none of these things. Man eventually established a system of interchange of commodities, which led to the creation of roadways over which traffic could be rudely transported on the backs of mules, horses, or other beasts of burden. As exchange and barter extended, the pack-horse became inefficient, and districts near the sea or placed on navigable rivers with easy access to the ocean became developed at the expense of other districts with equal facilities except transport.

A complex web of extreme events, such as devastating floods in some areas and severe water scarcity in others, are increasingly characterizing the global water crisis. This situation is made worse by the sneaky contamination of water sources with "forever chemicals" that do not decompose in the environment. A complex issue necessitating immediate action to guarantee access to clean, safe water for all populations is created by this pollution and the considerable water loss that occurs during delivery to customers as a result of aging infrastructure. Climate change is causing an increase in extreme events like floods and droughts, leading to unpredictable water availability. Water scarcity is also increasing, especially in areas with high population density and agricultural demands. Persistent organic pollutants like PFAS are contaminating water supplies, posing health risks due to their non-biodegradability. Inefficient infrastructure and leaky pipes contribute to significant...

Water quality is a crucial aspect of environmental health, as it directly impacts human health and ecosystems. There are several factors that contribute to water quality, including pollutants, temperature, acidity, and turbidity. Contaminants such as heavy metals, pesticides, and bacteria can have detrimental effects on both aquatic life and human populations. Monitoring and maintaining high water quality is essential to ensuring the sustainability of water resources for future generations. Implementation of effective management practices, such as proper waste disposal and water treatment, is necessary to preserve and protect water quality. Scientists and policymakers must work together to address the challenges of maintaining clean water sources in order to safeguard public health and maintain ecological balance.

This is the Part 35 of the Lecture. For the complete lecture on PCA click here . Principal Component Analysis (PCA) is a statistical technique commonly used in data analysis to simplify the complexity of large datasets by transforming the original variables into a smaller set of uncorrelated variables known as principal components. These components capture the maximum amount of variance in the data, thereby allowing for easier interpretation and visualization of the underlying patterns and relationships. PCA is widely used in fields such as machine learning, image processing, and genetics, providing researchers with valuable insights and actionable information for decision-making. By identifying the key dimensions driving variation in the data, PCA enables researchers to better understand and extract meaningful information from complex datasets.
