INTERFERENCE CANCELLATION USING ARTM TIER-1 WAVEFORMS IN AERONAUTICAL TELEMETRYAli, Tariq M., Saquib, Mohammad, Rice, Michael 10 1900 (has links)
ITC/USA 2005 Conference Proceedings / The Forty-First Annual International Telemetering Conference and Technical Exhibition / October 24-27, 2005 / Riviera Hotel & Convention Center, Las Vegas, Nevada / This paper describes and interference cancellation technique appropriate for ARTM Tier-1
waveforms. The technique requires the estimators for the bit sequences for the adjacent channels
as well as the power levels of the adjacent channels. Simulation results show that the interference
canceller allows a more dense “channel packing” thereby creating a channel utilization 67% ~
100% greater than the current IRIG 106 recommendations.

Interaction of the Nucleation Phenomena at Adjacent Sites in Nucleate BoilingSultan, Mohammed 11 1900 (has links)
<p> This investigation is an original study in nucleate
pool boiling heat transfer, consisting of two parts: an
experimental study and a theoretical study. The experimental
study was performed with water boiling at atmospheric pressure
on a single copper surface. Two different levels of heat
flux were investigated. For the lower level of heat flux
(92.21 kW/m2), three different levels of subcooling (0, 6.5,
12°C) were studied and for the higher level of heat flux
(192.11 kW/m2), two different levels of subcooling (0, 7.5°C)
were studied as well. </p> <p> The cross-spectral density function ·and the crosscorrelation
function were used to determine the time elapsed
(-r) between the start of bubble growth at two neighbouring
active sites with separation (S). The experimental results
indicate that for the lower level of heat flux at three
different levels of subcooling, the separation (S) and the
time elapsed (-r) are related. For the higher level of heat
flux at 0°C subcooling it was not possible to detect any
correlation, but for the 7.5°C subcooled condition a weak
correlation was found to exist. For the lower level of heat
flux, all the experimental data for the saturated and subcooled
boiling conditions plotted as (S-Rd) versus (T-Tg) drew
together into a single curve, indicating that a single
relationship could fit all the data. </p> <p> Three different theoretical models were devised in an attempt to·explain the experimental observations. The
first model involved heat diffusion in the water; the second
model was based upon the disturbance caused by the propagation
of a pressure pulse in a mixture of water and
vapour and finally the third model involved heat diffusion
in the solid. The first two models failed to give satisfactory
agreement with the experimental results, but the theoretical
predictions corresponding to heat diffusion through the
solid gave good agreement with the experimental findings. </p> / Thesis / Doctor of Philosophy (PhD)

ADJACENT CHANNEL INTERFERENCE MEASUREMENTS WITH CPFSK AND FQPSK-B SIGNALSLaw, Eugene 10 1900 (has links)
International Telemetering Conference Proceedings / October 22-25, 2001 / Riviera Hotel and Convention Center, Las Vegas, Nevada / This paper will present measured data in an adjacent channel interference (ACI) environment for
both filtered continuous phase frequency shift keying (CPFSK) and Feher’s patented quadrature
phase shift keying (FQPSK-B) [1]. The quantity measured was bit error probability (BEP) versus
signal energy per bit to noise power spectral density ratio (E(b)/N(o)). The interferers were either
CPFSK or FQPSK-B signals. The results presented in this paper will be for bit rates of 5 Mb/s, one
interferer 20 dB larger than desired signal, various channel spacings, and two different telemetry
receivers. The ACI test effort will collect data sets at several bit rates and with one and two
interferers. The results will be useful to system designers and range operators as they attempt to
maximize the number of Mb/s that can be simultaneously transmitted in the telemetry bands.

Analysis of persistent organic pollutants in benthic fishes in the adjacent waters of Hsiao-Liu-Chiu,TaiwanWu, Meng-chung 26 December 2010 (has links)
Persistent organic pollutants (POPs) have attracted the attention of scientists because they have the following characteristics: long-distance transmission, persistence, bioaccumulation and chronic toxicity. Due to their high hydrophobicity, POPs are easily absorbed by the suspended particles in the marine environment. The suspended particles then settle into the soil may pass through the food chain, resulting in bioaccumulation and biomagnifications and causing potentially hazardous effects on the environment and human health. This study focuses on the analysis of the persistent organic pollutants in different parts of 10 kinds of benthic fishes, including the muscle and visceral mass, adjacent to Hsiao-Liu-Chiu. The samples were analyzed using accelerated solvent extraction (ASE), and alumina column purification. Fifteen polycyclic aromatic hydrocarbons (PAHs) were determined by using gas chromatograph / mass spectrometer (GC/MS). After florisil column purification, polychlorinated biphenyls (PCBs) and 18 organochlorine pesticides (OCPs) were determined by using gas chromatograph / electron-capture detector (GC/ECD). The results showed that the concentration of PAHs range from 15 to 195 ng/g dw, with low ringed (3 rings) PAHs at a higher proportion. Total PCB concentrations range from 16 to 237 ng/g dw. The content of PCBs in muscles mainly consists of low chlorine numbers (1 to 4 chloride) -based, and in visceral and eggs the chlorine number (6 and 7 chlorine) are higher. The concentrations of OCPs range from 13 to 127 ng/g dw. Among the hexachlorocyclohexane (HCH) series, £^-HCH has the highest proportion, indicating the continued use of Lidane in recent years. In addition to the variance in POP levels among different species of fishes, different tissues also have high variations in PAH, PCB and OCP levels.

Investigating the Cooperative Behavior of Nonindustrial Private Forest Landowners when Stands are Spatially InterdependentVokoun, Melinda M. 11 April 2005 (has links)
This research examines how the harvesting behavior of nonindustrial private forest landowners, and their use of forestland for non-timber amenities, is affected by adjacent landowner behavior. The uncertainty an individual landowner has regarding adjacent landowners' preferences, and how the production of non-timber amenities on their own stands relies on the condition of adjacent stocks, is specifically addressed. Economic characterizations of substitutes and complements are employed to investigate the differences in optimal stock levels at the steady state in the production of amenities under various levels of cooperation among landowners. It is shown that there are externalities present when landowners do not coordinate management actions when parcels are spatially interdependent. The effects of spatial interdependencies on landowner behavior are further explored using data from a survey of forest landowners in Central Virginia. Findings suggest that forest landowners are willing to coordinate activities, and such decisions are determined by similar characteristics that function in predicting landowner behavior regarding timber harvesting. Further, landowners' decisions to use own and adjacent parcels were correlated, hinting at the spatial interdependencies of stocks in amenity valuations. Both the theoretical and empirical analyses suggest that the lack of coordination among landowners and its effects on stock management would be best addressed through the use of incentives to drive spatially efficient outcomes. / Ph.
