In addition, the average path that light traverses through the scintillator can be up to 50% longer than the straight path, due to reflection off the sides of the scintillator with reflective Mylar.
In a profound sense, vulnerability is the path to self-reflection.
In indoor environments with obstacles including people, there are mainly four kinds of signal paths: direct paths, reflection paths, diffraction paths, and penetration paths.
In typical NLOS circumstances, e.g. indoors and urban canyons, the direct path from the transmitter is blocked by buildings and other obstacles and the propagation wave may actually travel excess path lengths due to reflection, refraction and scattering.
The signals that arrive at the receiver can come from multiple paths, due to reflections off land or ocean, refraction, ducting, reflections off particles in the atmosphere, and at higher microwave frequencies, fading from rain, fog and other, changing atmospheric conditions.
The acoustic waves propagate at a very low speed of approximately 1500 m/s and the propagation occurs over multiple paths due to reflections from the surface and bottom of the sea.
We need you to be partners in your student's continued success, in part; their path to Duke is a reflection of their family support structure.
Hence, allowing the reflection paths to be close in delay between themselves could not degrade the performance so much, compared to allowing significant reflection paths to be close in delay to the direct path.
By assuming M direct paths from transmitters to a specific receiver and N reflection paths to the same receiver, the total power of the received optical signals, P T, is thereby calculated as: P T = ∑ i M P d, i + ∑ j N P r, j (5).
