Underwater radiated noise is u11-200ps part of the anthropogenic emissions into the environment and as such a pressing problem for the preservation of the marine ecosystem.In order to direct attention to the most relevant noise sources associated with ships it is crucial to precisely determine the local origins of the acoustic emissions.As acoustic
Studies with adult musicians show that beginning lessons before age seven is associated with better performance on musical tasks and enhancement in auditory and motor brain regions.It is hypothesized that early training interacts with periods of heightened neural development to promote greater plasticity and better learning and performance later in
The correlated color temperature (CCT) tunable white-light LED hbl5266ca cluster with extrahigh color rendering property has been found by simulation and fabricated, which consists of three WW LEDs (CCT = 3183 K), one red LED (634.1 nm), one green LED (513.9 nm), and one blue LED (456.2 nm).The experimental results show that this cluster can realiz
The complexity and variability of the internal environment of public buildings prompt to think about how to protect people in the fire and quickly reach the safe area.With the help of the Internet of Things, firefighting facilities, such as fire hydrants, fire extinguishers, safety evacuation signs, fire sprinklers, fire pumps, smoke, temperature,
