Autoregressive Integrated moving average (ARIMA ) models for time series forecasting
Real-world data which represents the time dimension can be used to forecast future scenarios using time series forecasting methods. Autoregression, moving average, autoregressive moving average and automated machine learning (automated ML) methods are time series forecasting methods which focus on… Continue reading

R-Squared
R-squared or coefficient of determination represents the proportion of the variance for a dependent variable explained by an independent variable. R-squared reflects the fitness of the derived model with its value ranging from 0 to 1. However, the presence of… Continue reading

Stormwater
Urban floods and runoff pollution can be caused by rapid urbanisation and climatic changes. Urban stormwater or urban floods can significantly damage urban infrastructure and human lives. Stormwater runoff often carries pollutants, bacteria, oil, grease and toxic chemicals to low-lying… Continue reading

Plate Tectonics
Global geological phenomena have been described by theory of plate tectonics. Plate tectonism assumes the movement of plates at earth’s crust influenced by convection of magma inside the mantle. Tectonic plates are the segments of lithosphere which move and change… Continue reading

Toxic Chemicals in the Environment
Different forms of harmful chemicals have been released into the soil, water and air from our activities. Chemicals which can cause serious health effects, poisoning or death when ingested, inhaled or absorbed have been classified as toxic chemicals (Worldometers, n.d.).… Continue reading

Hydraulic Fracturing
Hydraulic fracturing is a process of fracturing rock with the help of mixed fluid pressurization to obtain gas from the shale. Shallow wells have limitations of gas production due to low permeability of sedimentary rock containing gas. Hydraulic fracturing facilitates… Continue reading
