Polarimetric observations at low radio frequencies
… signals to be detected at relatively low radio frequencies. An interferometric polarisation mode has recently become available at the Giant Metrewave Radio Telescope (GMRT). A detailed analysis of the GMRT’s instrumental response is presented. The findings are used to create a polarisation …

Study of Pretraining Bias and Frequencies
… we experiment with numbers having high and low frequencies in the pretraining data to understand the impact of term frequencies on the model's performance. We also experiment with random and adversarial demonstrations to understand the pretraining bias present in the model. Through these …

Solid-state microwave amplification into millimetric frequencies
… final led to the decline of the technology at frequencies beyond S-band. The second period covers 1980 to 1987 and describes in detail the authors' contribution in the development of a milli-metric GaAs MESFET giving state of the art minimum noise performance in the mid 1980's. The work covers …

Dielectric properties of polymers at microwave frequencies
… of the dielectric properties at microwave frequencies is vital. The two polymer systems that have been investigated in this work are the epoxide system of EPON 828/ 4,4' DDS (diaminodiphenyl sulfone) and a series of well defined polystyrenes with varying end groups and end group …

Acoustic energy harvesting with emphasis on low frequencies
… acoustic energy harvesting with emphasis on low frequencies. At the beginning of this work, ambient acoustic power density is estimated and a comparison between the potential of sound and that of other ambient energy sources exploited for energy harvesting is performed. The interest in AEH is …

Terrestrial radio wave propagation at millimeter-wave frequencies
… on radio wave propagation at millimeter-wave frequencies. A measurement based channel characterization approach is taken in the investigation. First, measurement techniques are analyzed. Three types of measurement systems are designed, and implemented in measurement campaigns: a narrowband …

Motor data scaling by respiration frequencies in rest
… methods hence in this study we used respiration frequencies in rest data to scale task induced data and compared results with breathold scaling. The correlation between respiration frequencies and breathold signal was very good indicating presence of hemodynamic component in respiration. Scaling …

ImponderableSound: Using infrasonic frequencies within sonic art installations
… installation environment that emits infrasonic frequencies with the intention of affecting the human body both internally and externally. Imponderable Sound looks at sensation and the experience of sensation through haptic perception. This thesis considers both the artistic development of …

Influence of low frequencies on seismic impedance inversion
… very bandlimited, lacking both low and high frequencies. In this situation, recovering any of this bandwidth, especially low frequencies, can be helpful. The thesis will be focused on recovering low frequencies to improve impedance estimation and this includes trying to improve a frequency …
