We use German KiGGS data to add to existing knowledge about trends in vaccination-related attitudes and behavior.Looking at vaccinations against measles, we assess whether a low confidence in vaccination and vaccination complacency is particularly prevalent among parents whose children were born somewhat recently, as compared to parents whose Porta
The state-of-the-art geopositioning is the Global Navigation Satellite System (GNSS), which operates based on the satellite constellation providing positioning, navigation, and timing services.While the Global Positioning System (GPS) is widely used to position an Unmanned Aerial System (UAS), it is not always available and can be jammed, introduci
Road segmentation is an important task in the field of semantic segmentation, and the Deeplabv3+ algorithm, which is commonly used for road segmentation, has shortcomings, such as numerous parameters and a tendency to lose detailed information.Therefore, this paper proposes DCN-Deeplabv3+, an improved road segmentation algorithm with dual attention
Coolant in automotive engine cooling systems generally uses coolant with a minimum ethylene2 glycol mixture of 30 percent.Currently, the use of nanoparticles can be mixed in basic coolant between fluid and nanoparticles that have better thermal physical properties than pure coolant.The purpose of this study was to compare the results of CFD to test
