Assessing Wet and Dry Periods Using Standardized Precipitation Index Fractal (SPIF) and Polygons: A Novel Approach

Water
In the open literature, there are numerous studies on the normal and extreme (flood and drought) behavior of wet and dry periods based on the understanding of the standard precipitation index (SPI), which provides a series of categorizations by ...

SPIF of tailored sheets to optimize thickness distribution along the shaped wall

Procedia Manufacturing, 2019
Abstract Tailored blanks are widely used in industry for reducing the parts’ weight without affecting stiffness. In this study, the authors proposed the use of the tailored blanks with an alternative aim. Specifically, the attention has been focused on the use of an initial blank with variable thickness for overcoming one of the main drawback of ...
