A Variable Unit Hydrograph Incorporating Nonlinearity In Rainfall-Runoff Response Due To Antecedent Watershed Conditions, Aashis Sapkota

Electronic Theses and Dissertations Archive

Runoff generation in a watershed is a highly complex process whose estimation is vital in performing engineering tasks such as flooding risk assessments and design of hydraulic structures. Because natural rainfall-runoff processes are complex and inherently nonlinear, they are difficult to quantify or parametrize. In engineering hydrology, this issue has been mostly circumvented by using highly simplified, lumped approaches. Typically, losses are abstracted from a total precipitation hyetograph (representing either an actual or a design storm, depending on the application) to obtain the effective rainfall component, that is understood to result in the corresponding flood event. Then, this effective precipitation …

On The Synthesis Of Optimal Control Laws, Meir Pachter, Isaac E. Weintraub

Faculty Publications

In this paper we advocate for Isaacs' method for the solution of differential games to be applied to the solution of optimal control problems. To make the argument, the vehicle employed is Pontryagin's canonical optimal control example, which entails a double integrator plant. However, rather than controlling the state to the origin, we correctly require the end state to reach a terminal set that contains the origin in its interior. Indeed, in practice, it is required to control to a prescribed tolerance rather than reach a desired end state; achieving tight tolerances is expensive, and from a theoretical point of …

Finding Neverland? Artificial Intelligence And The Jurisprudence Of Legal Certainty, Omar Zaky

Theses and Dissertations

The development of artificial intelligence (AI) models that are capable of predicting the decisions of prominent courts – most notably the European Court of Human Rights and United States Supreme Court – provides us with an opportunity to revisit important jurisprudential debates regarding the quest for legal certainty. Through providing clear distinctions within formalistic jurisprudence, and its, subsequent, realist critique; this thesis seeks to analyze legal decision-making and its relationship with artificial intelligence. I argue that, AI’s deterministic nature and its support for the law being an “entirely self-contained process” does lend some credence to certain jurisprudential arguments. However, this …

Stimulation Of Ammonia Oxidizer And Denitrifier Abundances By Nitrogen Loading: Poor Predictability For Increased Soil N2o Emission, Yong Zhang, Feng Zhang, Diego Abalos, Yiqi Luo, Dafeng Hui, Bruce A. Hungate, Pablo García-Palacios, Yakov Kuzyakov, Jørgen Eivind Olesen, Uffe Jørgensen, Ji Chen

Biology Faculty Research

Unprecedented nitrogen (N) inputs into terrestrial ecosystems have profoundly altered soil N cycling. Ammonia oxidizers and denitrifiers are the main producers of nitrous oxide (N₂O), but it remains unclear how ammonia oxidizer and denitrifier abundances will respond to N loading and whether their responses can predict N-induced changes in soil N₂O emission. By synthesizing 101 field studies worldwide, we showed that N loading significantly increased ammonia oxidizer abundance by 107% and denitrifier abundance by 45%. The increases in both ammonia oxidizer and denitrifier abundances were primarily explained by N loading form, and more specifically, organic N …

The Effects Of Deepfakes And Synthetic Media On Communication Professionals, Axel Ebermann

Student Theses and Dissertations

The spread of misinformation and disinformation is regarded as one of the most salient challenges for communication professionals around the world.

Now, a new technology called "DeepFakes" or “Synthetic Media” has the potential to further uproot the infosphere. Artificial Intelligence (AI) will enable the mass creation of synthetic audio-visual content that resembles real videos, in which people will appear to say or do things they never actually said or did.

The existing literature predominantly focuses on three aspects of DeepFakes and Synthetic Media: the technical background, coverage of preexisting DeepFakes and possible solutions to combat the malicious use of the …
