Serve Or Skip: The Power Of Rejection In Online Bottleneck Matching, Barbara M. Anthony, Christine Chung

Computer Science Faculty Publications

We consider the online matching problem, where n server-vertices lie in a metric space and n request-vertices that arrive over time each must immediately be permanently assigned to a server-vertex.We focus on the egalitarian bottleneck objective, where the goal is to minimize the maximum distance between any request and its server. It has been demonstrated that while there are effective algorithms for the utilitarian objective (minimizing total cost) in the resource augmentation setting where the offline adversary has half the resources, these are not effective for the egalitarian objective. Thus, we propose a new Serve-or-Skip bicriteria analysis model, where the …

The Health Risks Of Chemicals In Personal Care Products And Their Fate In The Environment, Lisa Paulsen

Chemistry Honors Papers

Personal care products are everyday consumer products used to cleanse, enhance, or alter the appearance of the body, including, but not limited to, shampoos, body washes, lotions, and cosmetics. The regulations and safety information surrounding personal care products are severely lacking. The laws regulating the environmental fate of these chemicals and the harmful effects they can have on environmental ecosystems or organisms that are exposed to them are even more limited. However, studies have shown that the chemicals can have a dizzying array of health risks, including diseases on the rise in human populations such as diabetes, obesity, autism, ADHD, …

Mercury Speciation, Retention, And Abundance Of Genes Involved With Mercury Methylation In Fertilized Salt Marsh Sediments, Caroline Collins

Biology Honors Papers

Mercury (Hg) is a global pollutant which exists in both aquatic and terrestrial systems in three main forms including elemental Hg, ionic mercury, and methyl mercury, (MeHg), and Hg cycling plays an important role in ecosystems. Great Sippewisset Marsh, (GSM) in Falmouth MA has been chronically treated with fertilizer that contains heavy metals such as Hg in varying concentrations since the early 1970s and provides for an excellent location to study Hg contamination. The overall goal of this study is to analyze the key geochemical and microbial conditions that lead to MeHg production in the presence of the applied fertilizer. …

Explorations In The Gray Morality Of Conservation, Avery Whitlock

Art Honors Papers

I am interested in the areas of gray morality associated with conservation science. This science focuses on the protection of biological diversity primarily through the protection of species and their environments, and the management of human impact upon these.

This interest was sparked by personal explorations in scientific illustration and the field of conservation. The scientific observations and dynamic illustrations of John James Audubon led to my focus specifically on birds.

Similarly vital in realizing this interest were initial studies of motion I created through animation. Animated studies of motion, as fabrications of life, evolved into an interest of how …

Wind, Waves And Surge: An Analysis Of The Movement And Post-Storm Recovery Of Bushy Point Beach In Groton, Ct, Grace Medley

Physics, Astronomy and Geophysics Honors Papers

Barrier beaches are highly dynamic systems that respond to variations in wave energy, increases in storm surge heights and changes in relative sea level. Bushy Point barrier beach is a barrier spit located in Groton, Connecticut, and is one of the last unconstrained barrier systems in the State of Connecticut. Since 1934, the morphology of the beach has been changing in response to storm events as well as the local rise in sea level. On September 21, 1938, a category three hurricane made landfall in southern New England and devastated many coastal communities, including a summer community on Bushy Point …

Experimental Simulations Of Recurring Slope Lineae On The Surface Of Mars, Elizabeth Eddings

Physics, Astronomy and Geophysics Honors Papers

Recurring Slope Lineae (RSL) are active surface features found on rocky Martian slopes commonly in the southern hemisphere equatorial to mid-latitude regions. These low albedo, dark streaks on Mars demonstrate seasonal characteristics;; they appear and grow darker and longer in warm months and fade to possible disappearance in colder months. One proposed mechanism for the formation and evolution of these features by McEwen et al. (2011) is the melting of subsurface water on Mars. The goal of this study was to test this hypothesis by reconstructing features similar to RSL in the lab that display the same seasonal …

Cultivating Sustainable Cities: A Comparative Study Of Urban Agriculture In Mumbai, India And New York City, Usa, Kristina Satterlee

Environmental Studies Honors Papers

Urban agriculture has the potential to be a source of great social and environmental good within a city. This study couples in-depth interviews with urban farmers with secondary research to provide a holistic understanding of the urban agriculture movement in Mumbai, Maharastra, India and New York City, New York, USA. Through this resource, it became apparent that the two movements vary drastically in terms of size, scope, resource availability, and movement goals. Despite these differences, the research points to one striking similarity. In both cities, farms and gardens in lower income areas have access to a far smaller body of …
