Assessing wet and dry periods using Standardized Precipitation Index Fractal (SPIF) and polygons: A novel approach
(Multidisciplinary Digital Publishing Institute (MDPI), 2024)
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 ...
Error performance enhancement and complexity reduction in OFDM systems via coordinate interleaving under practical impairments
(Turkiye Klinikleri, 2024)
In this work, subcarrier coordinate interleaving (CI) is implemented to orthogonal frequency division multiplexing (OFDM) systems with the aim of both enhancing the error performance and reducing the implementation complexity. ...
Dual-polarized wideband 5G N77 band slotted MIMO antenna system for next-generation smartphones
(Institute of Electrical and Electronics Engineers Inc., 2024)
In this work, a slotted wideband eight-element multiple-input multiple-output (MIMO) antenna system is presented, which covers the N77 (3.2-4.2 GHz) frequency band. The MIMO antennas are printed on a 0.8-mm-thick FR-4 ...
Fuzzy standardized precipitation index (FSPI) for drought early warning procedure
(Springer, 2024)
There are several standardized meteorological, hydrological, agricultural, and environmental indices for drought classification into a set of dry categories all of which are derived from the basic concept of standardized ...
