This paper shows experimentally that standard wireless networks which measure received signal strength (RSS) can be used to reliably detect human breathing and estimate the breathing rate, an application we call “BreathTaking”. We present analysis showing that, as a first order approximation, breathing induces sinusoidal variation in the(More)
The phosphoprotein obtained by the neutral pH tris buffer extraction of acetic acid demineralized bovine dentin has been compared with the phosphoprotein extracted directly during the neutral pH EDTA demineralization process. The phosphoproteins isolated by DEAE-cellulose chromatography from the neutral pH EDTA demineralization extract are not identical to(More)
Measurements of received signal strength (RSS) on wireless links provide position information in various localization systems, including multilateration-based and fingerprint-based positioning systems, and device-free localization systems. Existing localization schemes assume a fixed or known transmit power. Therefore, any variation in transmit power can(More)
The rapidly growing field of multi-antenna communication contains a great deal of promise for satisfying the future demands of high-speed data transfer across wireless networks. Interference from external sources as well as adjacent users reduces the capacity of the system and must be taken into account. This is particularly true in applications where users(More)
Total effect of action of the wood-destroying fungusPolyporus palustris, belonging to the ‘brown rot’ group, has been studied on mango (Mangifera indica) and chorapine (Hardwickia pinnata) woods, for various periods of attack at definite intervals and the lignin liberated was extracted. It was observed that the production of lignin was found to increase; if(More)
Multiantenna measurements were performed in three small aircraft (Beech Baron 58-P, Rockwell T-39 Sabreliner, and the Diamond DA-42 Twin Star) and compared to those of six statistical multiantenna channel models, being the Gaussian, Nakagami-m, Weibull, hyperRayleigh, virtual, and Weichselberger models. The results were also compared to that of a(More)
Microwave Ablation (MWA) is a promising technology for treating hepatic tumors. Combined macromolecular thermo-targeted chemotherapy and MWA are expected to provide better tumor control than either method independently. The MWA will heat and destroy the tumor core. It will also produces a hyperthermic zone for further destruction at the tumor margin by(More)
