The implementation of wireless communications in office buildings requires the profound knowledge of signal penetration within buildings. This knowledge should include information, concerning the in-building structure that strongly affects the signal transmission. This paper contributes to the modeling of propagation losses and measurement techniques in modern office buildings for Spread Spectr...

industrial organizations are complex systems` where the interactions among the various functions such as sales, distribution, manufacturing, materials, finance, human resources and maintenance have to be man-aged towards a common purpose of delivering the customers satisfaction. however, since most of these or-ganizations have a `functional structure`, each function or department works towards ...

The presence of loss limits the precision of an approach to phase measurement using maximally entangled states, also referred to as NOON states. A calculation using a simple beam-splitter model of loss shows that, for all nonzero values L of the loss, phase measurement precision degrades with increasing number N of entangled photons for N sufficiently large. For L above a critical value of appr...
