Observation of Low Earth Orbit Debris using GNSS Radar
… the receiver experiences different relative carrier phases throughout the observation period, so the cross-correlation interference is not persistent. We have shown that on the order of minutes, signals with non-linear and large relative Doppler offsets are uncorrelated. We simulated a …

Trace element geochemistry of marine biogenic particulate matter
… and trace element composition of particulate carrier phases. Elements examined through some or all of these experiments were: C, N, P, Mg, Ca, Si, Fe, Mn, Ni, Cu, Cd, Al, Ba, and Zn. Emphasis was placed on the identification of trace element/major element ratios in the biogenic materials. The …

Source localization via time difference of arrival
… the TDOA information, it utilizes the relative carrier phases of the received signals among pairs of sensors. A location estimator is constructed based on a maximum likelihood metric. The potential of accuracy improvement by the coherent approach is shown through the Cramer Rao lower bound …

Coherent Control of Molecular Dynamics with Shaped Femtosecond Pulses
… with tunable wavelengths, delays, and relative carrier phases between the single pulses. The basic principle, phase conservation during optical parametric amplification, has been demonstrated. With this setup, control experiments which require pulses with the above described attributes in …

Motion tracking problems in Internet of Things (IoT) and wireless networking
"The dissertation focuses on inferring various motion patterns of internet-of-things (IoT) devices, by leveraging inertial sensors embedded in these objects, as well as wireless signals emitted (or reflected) from them. For instance, we use a combination of GPS signals and inertial sensors on …

Iron Isotope Cosmochemistry
… 54Cr anomalies have been long observed, the carrier phases and the stellar origin had not been identified until our research. By measuring 58Fe, I put constraints on the nucleosynthetic origins: most probably Type II supernovae).</p><p>From Chapter 3 to 7, I emphasize mass-dependent …
