A New Fractional Order Hold and Its Capability in Frequency Response and Zero Placement
Journal of Applied Mathematics, 2013 This paper introduces a new holder with application on digital control systems. This holder is a combination of fractional order hold (FROH) and zero-order hold (ZOH) that has the capability of both holders and a frequency response better than both of ...

Conservation Genomic Analysis of the Croatian Indigenous Black Slavonian and Turopolje Pig Breeds
Frontiers in Genetics, 2020 The majority of the nearly 400 existing local pig breeds are adapted to specific environments and human needs. The demand for large production quantities and the industrialized pig production have caused a rapid decline of many local pig breeds in recent

Timing and Extent of Inbreeding in African Goats
Frontiers in Genetics, 2019 Genetic characterization of African goats is one of the current priorities in the improvement of goats in the continent. This study contributes to the characterization effort by determining the levels and number of generations to common ancestors (“age”)
