Auditory system response to radio frequency energy. Technical note.
C LASSICALL Y, the auditory and visual systems have been distinguished in part by the "fact" that the two systems respond to different types of energy, acoustic and electromagnetic, respectively. Our Laboratory, however, has obtained data which suggests that this fact may not be correct. The textbooks state that sound energy is generated only by vibrating bodies and is transmitted ed by wave mo...
متن کاملThrust Measurements of a Radio Frequency Plasma Source
There is interest in the use of a heliconplasma source in propulsive applications as both an ion source anda thruster. Development of a helicon thruster requires a performance baseline as a basis for future optimization and modification. For the first time, the thrust of a helicon plasma source ismeasured using a null-type inverted pendulum thrust stand at an operating pressure of 2 × 10−5 torr...
متن کاملRADIO FREQUENCY NOISE MEASUREMENTS AND MODELS FOR INDOOll
This paper describes . average and impulsive noise measurements inside several office buildings and retail stores. The receiver had a 70-dB dynamic range and operated at 918 MHz, 2.44 GHz, and 4.0 GHz with a nominal 40 MHz 3-dB RF bandwidth. Omni-directional and directional antennas were used to investigate the characteristics and sources of RF noise in indoor channels. Statistical analyseSof -...
متن کاملNote on non-entangling measurements
The general form of non-entangling unitary maps for measurement schemes is determined. It is shown that any POVM admits a non-entangling measurement. We prove the following. Proposition 1 Let H1,H2 be complex separable Hilbert spaces, φ0 a unit vector in H2. Assume U : H1 ⊗ H2 → H1 ⊗ H2 is a unitary map such that for all φ ∈ H1, U(φ ⊗ φ0) = φ′ ⊗ φ′ for some unit vectors φ′ ∈ H1, φ′ ∈ H2. Then U...
متن کاملA Note on Fire Frequency
5 The concepts of hazard of burning, fire interval and fire cycle are 6 considered. It is claimed that the current notion of fire cycle is poorly 7 defined (since the time required to burn a specified area is a random 8 variable). It is shown that the expected time to burn an area equal 9 to the study area normally exceeds the fire interval (the average time 10 between fires at any location). I...
