Background Estimates of dominance variance in dairy cattle based on pedigree data vary considerably across traits and amount to up to 50% of the total genetic variance for conformation traits and up to 43% for milk production traits. Using bovine SNP (single nucleotide polymorphism) genotypes, dominance variance can be estimated both at the marker level and at the animal level using genomic dominance...
The integration of strong security functionality to radio-frequency identification (RFID) tags operating in the ultra-high frequency (UHF) range is challenging. Main limiting factors are chip size and power consumption. In this work we present the design of the digital part of a security-enhanced UHF RFID tag that uses the Electronic Product Code (EPC) Generation-2 (Gen-2) standard for communication...
Renewable energy resources like hydro power plants play a more important role in the upcoming future of power grids. Thereby, a full flexibility of utilizing the grid capabilities in terms of active and reactive power production in generating mode as well as power consumption in pumping mode in conjunction with the best available efficiency of both electric and hydraulic devices gains in significance...
In order to fulfil the new challenges within power grids arising from an increasing utilization of renewable energy resources, there is an upcoming demand for pumped storage hydro power plants. Thereby, a full flexibility of active and reactive power production in generating mode as well as power consumption in pumping mode in conjunction with the best available efficiency of both electric and hydraulic...
