There are a huge number of harmonics in the railway power supply system.Accurately estimating the harmonic impedance of the system is the key to evaluating the harmonic emission level of victory white camellia the power supply system.A harmonic impedance estimation method is proposed in this paper, which takes the Gaussian mixture regression (GMR)
On the way from the Internet of things (IoT) to the Internet of underground things (IoUT) the main challenge is antenna design.The enabling technologies still rely on simple design and low cost, but the systems are more complex.The LoRa-based system combined with a machine learning approach can be used for the estimation of essie cause and reflect
The Dry Chaco in South America is a semi-arid ecoregion prone to dryland salinization.In this region, we investigated coarse-scale surface soil moisture (SM), soil temperature, soil salinity, and vegetation, using L-band microwave brightness temperature (TB) observations and retrievals from the soil moisture ocean salinity g fuel spiderverse (SMOS)
Abstract Small ruminants are suited to a wide variety of habitats and thus represent promising study models for identifying genes underlying adaptations.Here, we considered local Mediterranean breeds of goats (n = 17) and sheep (n = 25) from Italy, France and Spain.Based on historical archives, we selected the breeds potentially most linked to a te
The exponential increase in the use of altimeter data in oceanographic studies in the past two decades has improved the knowledge of the processes that govern the interaction between the ocean and the atmosphere.One of these processes is the response of the ocean to atmospheric pressure variations, which has been deeply analysed in the past.That re
