A comparative assessment of online GNSS processing services for geodetic control: insights from the ethiopian network

Abstract This study compares four online GNSS processing services AUSPOS, TrimbleRTX, OPUS, and CSRS-PPP using 72-h static GNSS data from 12 geodetic control stations in Ethiopia. Observations collected with a Leica GS10 receiver were processed by each service and evaluated again...

Modeling of land use land cover change dynamics using google earth engine and machine learning techniques in the Abaya-Chamo sub-basin, Ethiopia

Abstract Modelling land use and land cover change analysis is employed to categorize historical and predicted spatial-temporal land cover dynamics at regional and local scales. This research examined historical and projected future land use and land cover (LULC) dynamics utilizin...

Comparative analysis of African cattle, sheep and goat genomes reveal convergence and divergence to contrasting environments

African livestock have co-existed and co-adapted to Africa’s diverse eco-climates which have likely impacted their genomes. Such impacts however remain poorly investigated across multiple livestock species. Using whole genome sequences of African cattle, sheep, and goats in Ethio...

A review of machine learning, deep learning and large language model based harmonized system code classification techniques for import and export commodities

The Harmonized System (HS) code is a systematically created, structured, multi-purpose nomenclature used to classify import and export commodities for the purposes of facilitating trade transactions, ensuring confidentiality, maintaining statistics, and transporting goods. In thi...

Development and Characterization of Functionally Graded Sisal/Glass Fiber-Reinforced Polymer Composites

Structural applications require materials that provide an optimal balance of strength, durability, and sustainability. This study develops functionally graded sisal/glass fiber-reinforced polymer composites and evaluates their tensile, compressive, and flexural properties, as wel...
