Communication and time distortion
Communication systems always suffer time distortion. At the physical layer asynchrony between clocks and motion-induced Doppler effects warp the time scale, while at higher layers there are packet delays. Current wireless underwater modems suffer a significant performance degradation when …

Distortion Tolerant Fan Design
… at the rotor tip to analyse stall inception in distortion. The necessary transonic blade design modification led to a loss of efficiency of 0.5% and reduction of mass flow of 2%, which were attributed to a rise in blockage due to blade thickening and an increase in profile loss in the hub …

Tidal distortion in shallow estuaries
… focuses on sea surface measurements. Non-linear distortion of the tide at Nauset is characterized by the strong growth of harmonics and compound constituents particularly in the quarter-diurnal band. Phase relationships between the forced constituents and their parent produce a flood-dominant …

Black Genius: An Achievement Distortion
… to frame the issue more accurately: Achievement Distortion, Connection Gap, and Black Genius. Groundtruthed by Black educators, Black Genius is defined as an intelligence that exists outside of the traditional, status quo, Western conceptualization of intelligence. Black Genius is rooted in Black …

Ipsative Score Distortion on Affinity 2.0
This study investigated distortion that occurs when raw scores are converted to ipsative scores on Affinity 2.0, a relatively new instrument for assessing sexual interest. Using a sample of 146 non-offending, heterosexual females, this study examined the characteristics of distorted ipsative score …

Distortion-Tolerant Communications with Correlated Information
… dissertation is devoted to the development of distortion-tolerant communication techniques by exploiting the spatial and/or temporal correlation in a broad range of wireless communication systems under various system configurations. Signals observed in wireless communication systems are often …

Enigmatic commercials: Schema distortion in television advertisements
… have begun to use commercials that employ schema distortion that make the commercial seem enigmatic to the viewer. Recently, research in communication, specifically the news media, has focused on the processes of learning and recall using schema theory; The method used 12 commercials, 6 identified …

CFD modelling of flow distortion using OpenFOAM
This thesis presents a computational fluid dynamic (CFD) study of flow related to wind engineering. The open source CFD code OpenFOAM was applied to three cases (i) flow over an oil platform, (ii) flow over a complex terrain and (iii) flow over a met mast. In order to verify the results, …

Digital Pre-Distortion: The Implementation, Minimisation, & Estimation
… technique can be applied to a PA. Digital Pre-Distortion (DPD) has been widely demonstrated in industry and academia to perform linearisation. Some issues concerning DPD are related to implementation efficiency, robust function estimation and the complexity of DPD solutions. This dissertation …

Value at risk and the distortion operator
… models back to the actual measure. We propose a distortion operator to serve as such a bridge between the actual and risk neutral distributions.

Males' Ipsative Score Distortion on Affinity 2.0
This study investigated the frequency of distortion that occurs when raw score patterns of Affinity 2.0, a viewing time measure designed to assess sexual interest, are converted to ipsative scores. Eighty-eight percent of a sample of ninety-nine non-pedophilic, exclusively heterosexual males' …

Privacy protection through limited load signal distortion
Advanced techniques of Non-Intrusive Load Monitoring (NILM) can provide power consumers with opportunities to easily and accurately track their own energy usage. However, as with any other powerful technology, there is a darker side to NILM. Since detailed monitoring requires only information about …
