(6) If we now assign T0 to be the undisturbed air temperature of the surroundings, p as the small perturbation in pressure due to an acoustic wave and P0 as the ambient pressure we can derive the change in temperature occurring with a passing acoustic wave. ∆T is very small and is approximately ±0.23C with a very high sound level of 140 dB(SPL), ambient temperature of 20C, and an ambient pressu...

Molecular dynamics simulations are used to model the evaporation of a Lennard–Jones argon nanodroplet into its own vapor for a wide range of ambient temperatures and ambient pressures. The transitions from i high to low Knudsen number evaporation and ii subcritical to supercritical evaporation are observed. At a low ambient pressure of 0.4 MPa, the initial droplet Knudsen number is 1 and the dr...

This paper proposes the use of an autonomous assistant mobile robot in order to monitor the environmental conditions of a large indoor area and develop an ambient intelligence application. The mobile robot uses single high performance embedded sensors in order to collect and geo-reference environmental information such as ambient temperature, air velocity and orientation and gas concentration. ...

OBJECTIVE Each year, children die from heat stroke after being left unattended in motor vehicles. In 2003, the total was 42, up from a national average of 29 for the past 5 years. Previous studies found that on days when ambient temperatures exceeded 86 degrees F, the internal temperatures of the vehicle quickly reached 134 to 154 degrees F. We were interested to know whether similarly high tem...
