Quantifying Volatile Fatty Acid Concentrations During The Pretreatment And Anaerobic Digestion Process, Sascha Boutelle Dec 2022

Quantifying Volatile Fatty Acid Concentrations During The Pretreatment And Anaerobic Digestion Process, Sascha Boutelle

Theses and Dissertations

Producing renewable energy from biomass or from the wastewater treatment process has gained momentum in the past 20 years. Anaerobic digestion has historically been used as one step in the waste treatment process, to both reduce the mass of waste that needs to be disposed of and to generate biogas. This process is typically only able to reduce 30-40% of the waste mass because of the recalcitrant nature of the waste streams being treated. Anaerobic pretreatment with the thermophilic bacteria Caldicellulosiruptor bescii (C. bescii) has been proven to increase the percentage of mass digested and consequently increase methane production to …

Torward Real-World Cross-View Image Geo-Localization, Sijie Zhu

Electronic Theses and Dissertations, 2020-2023

Cross-view image geo-localization aims to determine the locations of street-view query images by searching in a GPS-tagged reference image database from aerial view. One fundamental challenge is the dramatic view-point/domain difference between the street-view query images and aerial-view reference images. Recent works have made great progress on bridging the domain gap with advanced deep learning techniques and geometric prior knowledge, i.e. the query is aligned at the center of one aerial-view reference image (spatial alignment) and the orientation relationship between the two views is known (orientation alignment). However, such prior knowledge of the geometry correspondence of the two views is …

Tidal disruption events (TDEs) are bursts of electromagnetic energy that are released when supermassive black holes at the centres of galaxies violently disrupt a star that passes too close1. TDEs provide a window through which to study accretion onto supermassive black holes; in some rare cases, this accretion leads to launching of a relativistic jet2–9, but the necessary conditions are not fully understood. The best-studied jetted TDE so far is Swift J1644+57, which was discovered in γ-rays, but was too obscured by dust to be seen at optical wavelengths. Here we report the optical detection of …

Uneasy Attachments: Postcolonial Anglophilia And Identity Formation In Twentieth-Century Anglophone Autobiographies, Anwesha Kundu Dec 2022

Uneasy Attachments: Postcolonial Anglophilia And Identity Formation In Twentieth-Century Anglophone Autobiographies, Anwesha Kundu

Arts & Sciences Graduate Student Theses and Dissertations

This dissertation focuses on the impact of anglophilia on identity formation in the British empire. Since Britishness was an identity unavailable to non-white citizens of the empire, this attachment was necessarily unrequited. Analyzing works by Cornelia Sorabji, E.R. Braithwaite, V.S. Naipaul, and Tsitsi Dangarembga, I argue that the critical significance of anglophilia does not lie in the postcolonial subject’s success or failure in achieving a British-coded identity, but in the ways in which an affiliation to Britishness can be mobilized to accomplish a variety of personal, political, and social ends. I use a range of autobiographical literature—travel narratives, autobiographical novels, …
