Zeros Of Convex Combinations Of Elementary Families Of Harmonic Functions, Rebekah Ottinger

Theses and Dissertations

Brilleslyper et al. analyzed a one-parameter family of harmonic trinomials, and Brooks and Lee analyzed a one-parameter family of harmonic functions with poles. Each family was explored to find the relationship between the size of the parameter and the number of zeros of the harmonic function. In this thesis, we examine convex combinations of members of these families. We determine conditions under which the critical curves separating the sense-preserving and sense-reversing regions are circular. We show that the number of zeros of a convex combination can be greater than the maximum number of zeros of either part.

Procedural Pre-Training For Visual Recognition, Connor S. Anderson

Theses and Dissertations

Deep learning models can perform many tasks very capably, provided they are trained correctly. Usually, this requires a large amount of data. Pre-training refers to a process of creating a strong initial model by first training it on a large-scale dataset. Such a model can then be adapted to many different tasks, while only requiring a comparatively small amount of task-specific training data. Pre-training is the standard approach in most computer vision scenarios, but it's not without drawbacks. Aside from the cost and effort involved in collecting large pre-training datasets, such data may also contain unwanted biases, violations of privacy, …

Zinc Oxide Nanostructures Synthesized By Hot Water Treatment For The Photocatalytic Degradation Of Organic Pollutants In Water, Ranjitha Kumarapuram Hariharalakshmanan

Theses and Dissertations

Photocatalysis using nanostructured semiconductors for the degradation of organic pollutants has received significant attention as an advanced water treatment method. A photocatalyst absorbs light with energy greater than or equal to its band gap and generates electron-hole pairs. These electrons and holes take part in redox reactions in water to generate reactive oxygen species, such as hydroxyl radicals and superoxide anions, which can break down organic contaminants. However, this method has some challenges, such as electron-hole recombination, which reduces the efficiency, high cost of nanostructure synthesis, and reduced durability of nanostructured photocatalysts in suspension form. The immobilization of photocatalyst nanostructures …

Towards An Inclusive Media Policy Framework Targeting Adolescents In Egypt, Saja Elgredly

Theses and Dissertations

For years, adolescents have been lost between adulthood and childhood. This is even reflected in the policies that directly affect their lives and well-being. In Egypt, there has hardly been a clear political line on how the media should deal with adolescents. As this age group belongs to childhood, most of the laws and regulations are hardly dedicated to address them despite their different characteristics. Within the Egyptian context, there are children's laws concerned with basic children's rights and other laws that relate to the media. However, we notice a gap in adolescent-friendly laws, policies and regulations, especially in the …

How Do They See Us?: Unhcr's Representations Of Syrian Refugees In “Every Second Counts” Campaign, Marah Khalid

Theses and Dissertations

Representation is not just an opinion; it is the recreation of realities, facts, and stories that encourage receivers, who are readers and viewers, to build perceptions of a certain topic, objects, events, and human beings. Studying the representation of refugees in the media, UN agencies, and International organizations' press releases, videos, and images has been the main focus for many scholars for decades. However, little is known about refugees' perspectives on visuals produced by UN agencies.
