A spatial duration-augmented framework for drought persistence
Touqeer Ahmad, Thordis Linda Thorarinsdottir
Drought monitoring across heterogeneous climate regions requires explicit modeling of drought persistence rather than relying solely on index classification. We develop a Bayesian…
Space time modeling for drought classification and prediction
Touqeer Ahmad, Taha Hasan
The Standardized Precipitation Index (SPI) is a critical tool for monitoring drought conditions, typically relying on normalized accumulated precipitation. While longer historical…
Order of Addition in Orthogonally Blocked Mixture and Component-Amount Designs
Taha Hasan, Touqeer Ahmad
Mixture experiments often involve process variables, such as different chemical reactors in a laboratory or varying mixing speeds in a production line. Organizing the runs in ortho…
Order of Addition in Mixture-Amount Experiments
Taha Hasan, Touqeer Ahmad
In a mixture experiment, we study the behavior and properties of mixture components, where the primary focus is on the proportions of the components that make up the mixture ra…
