To help characterize indoor radio frequency propagation at cellular frequencies, tests were conducted to measure signal strength received from various types of RF distribution systems.
For indoor tracking in environments where the tags being tracked must transmit radio pings, inexpensive off-the-shelf hardware makes it practical to have approximately one or more receivers per roo

Wireless local area networks (WLANs) most commonly use the Industrial, Scientific, and Medical (ISM) frequency band, at 2.4 GHz.
The airborne concentrations of chloride, nitrate, sulfate, sodium, ammonium, potassium, magnesium, and calcium in fine particles (nominally 2.5micron diameter) and coarse particles (2.5-15micron) h
We previously reported deposition velocities for chloride, nitrate, sulfate, sodium, ammonium, potassium, magnesium, and calcium associated with fine and coarse particles at telephone company switc
In previous work, the indoor/outdoor ratios and surface accumulation rates of ionic substances contained in fine and coarse particles were determined at low-occupancy office buildings containing el
Integrated Network Design Tool (INDT) Studio is a suite of tools to optimally plan, design and analyze service and transport networks.
Polarized neutron scattering techniques have been used to study the spatial distribution and temperature-dependence of the magnetization induced in single crystals of UPt(3), UBe(13), and CeCu(2)S
Six heretofore unobserved transitions within the conduction band of a AlAs/GaAs quantum well are reported, two of which are forbidden in a symmetric quantum well.
