Provenance Of The Pythian Cave Conglomerate, Northern California: Implications For Mid-Cretaceous Paleogeography Of The U.S. Cordillera, Kathleen D. Surpless, Gregory Alan Augsburger

Earth and Environmental Geosciences Faculty Research

Provenance analysis of middle Cretaceous sedimentary rocks can help distinguish between disparate tectonic models of Cretaceous Cordilleran paleogeography by establishing links between sediment and source, as well as between currently separated basins. This study combines new detrital zircon age data and compositional data with existing provenance data for the Pythian Cave conglomerate, an informally-named unit deposited unconformably on the eastern Klamath Mountains, to test possible correlations between the Pythian Cave conglomerate and similar-age deposits in the Hornbrook Formation and the Great Valley Group. These provenance results indicate that restoring Late Cretaceous clockwise rotation of the Blue Mountains adds a significant …

Distance Metric Learning From Uncertain Side Information With Application To Automated Photo Tagging, Lei Wu, Steven C. H. Hoi, Rong Jin, Jianke Zhu, Nenghai Yu

Research Collection School Of Computing and Information Systems

Automated photo tagging is essential to make massive unlabeled photos searchable by text search engines. Conventional image annotation approaches, though working reasonably well on small testbeds, are either computationally expensive or inaccurate when dealing with large-scale photo tagging. Recently, with the popularity of social networking websites, we observe a massive number of user-tagged images, referred to as "social images", that are available on the web. Unlike traditional web images, social images often contain tags and other user-generated content, which offer a new opportunity to resolve some long-standing challenges in multimedia. In this work, we aim to address the challenge of …

Liability For Future Harm, Ariel Porat, Alex Stein

Coase-Sandor Institute for Law & Economics Research Paper Series

This Article considers the possibility of imposing liability in torts for a wrongfully created risk of future harm. We examine the American and English court decisions pertaining to this issue and consider whether a probability-based compensation for the victim's expected—albeit not yet materialized—harm is just and efficient. We demonstrate how the virtues of a legal regime that allows a tort victim to recover compensation for her expected harm overshadow its vices. We conclude that a person's risk of sustaining harm in the future should be actionable whenever the risk is substantial. We further conclude that it should be left to …

A New Look At Richardson Number Mixing Schemes For Equatorial Ocean Modeling, Edward D. Zaron, James N. Moum

Civil and Environmental Engineering Faculty Publications and Presentations

A reexamination of turbulence dissipation measurements from the equatorial Pacific shows that the turbulence diffusivities are not a simple function of the gradient Richardson number. A widely used mixing scheme, the K-profile parameterization, overpredicts the turbulent vertical heat flux by roughly a factor of 4 in the stably stratified region between the surface mixed layer and the Equatorial Undercurrent (EUC). Additionally, the heat flux divergence is of the incorrect sign in the upper 80 m. An alternative class of parameterizations is examined that expresses the mixing coefficients in terms of the large-scale kinetic energy, shear, and Richardson number. These representations …

How Does A Visual Monitoring System Foster Sustainable Behavior?, Melissa Haeffner, Federico Casalegno

Environmental Science and Management Faculty Publications and Presentations

Americans spend upwards of 90% of each day in buildings that account for two-thirds of electricity usage. Because the supply of smart buildings will take time to catch up with demand, efforts are sought to develop informed and educated people to live and work in these “dumb” buildings. Additionally, energy efficiency alone may be inadequate to achieve major reduction in carbon emissions (Darby, 2006). Finding ways to intentionally change the lifestyle behavior in a household should have significant implications in reducing environmental impacts as fossil energy use in resident homes is directly related to the exploitation of natural resources and …

Practical Approximations To Quantify The Impact Of Time Windows And Delivery Sizes On Freight Vmt In Urban Areas, Miguel A. Figliozzi

TREC Final Reports

This paper studies approximations to the average length of Vehicle Routing Problems (VRP). The approximations are valuable for strategic and planning analysis of transportation and logistics problems. The research focus is on VRP with varying number of customers, demands, and locations. This modeling environment can be used in transport and logistics models that deal with a distribution center serving an area with daily variations in the demand. The routes are calculated daily based on what freight is available. New approximations and experimental settings are introduced. Average distance travelled is estimated as a function of the number of customers served and …

Statistical Hypothesis Testing For Postreconstructed And Postregistered Medical Images, Eugene Demidenko

Dartmouth Scholarship

Postreconstructed and postregistered medical images are typically treated as the raw data, implicitly assuming that those operations are error free. We question this assumption and explore how the precision of reconstruction and affine registration can be assessed by the image covariance matrix and confidence interval, called the confidence eigenimage, using a statistical model-based approach. Various hypotheses may be tested after image reconstruction and registration using classical statistical hypothesis testing vehicles: Is there a statistically significant difference between images? Does the intensity at a specific location or area of interest belong to the “normal” range? Is there a tumor? Does the …

Performance Optimisation Of The Ait Campus Wireless Mesh Network Deployment, Eduardo Brito, Robert Stewart, John Allen, M. H. Hassan

9th. IT & T Conference

The deployment of an 802.11x wireless mesh network in urban areas is a complex task and is traditionally based on an exhaustive site survey, rules-of-thumb or past experiences. In this research we propose exploring the spatial distribution of the clients, the topology and the clutter using software tools from Motorola in a VoWiFi mesh network before deployment. The objective is to obtain the optimal position for the wireless access points that allows an increase in the overall capacity and performance. The cost savings inherent in running real-time applications over IP based wireless mesh networks will be of interest to industry, …

An Improved Camshift Algorithm For Target Tracking In Video Surveillance, Chunrong Zhang, Yuansong Qiao, Enda Fallon, Chiangqiao Xu

9th. IT & T Conference

Target tracking in a cluttered environment remains a challenging research topic. The task of target tracking is a key component of video surveillance and monitoring systems. In this paper, we present an improved CamShift algorithm for tracking a target in video sequences in real time. Firstly, a background-weighted histogram which helps to distinguish the target from the background and other targets is introduced. Secondly, the window size is calculated to track the target as its shape and orientation change. Finally, we use a Kalman Filter to avoid being trapped by a local maximum. The introduction of the Kalman Filter also …

Qos-Aware Iptv Routing Algorithms, Patrick Mcdonagh, Philip Perry, Liam Murphy

9th. IT & T Conference

The aim of this paper is to describe how QoS (Quality of Service) metrics such as packet delay can be used to optimise the routing algorithms used in a network where IP Television (IPTV) content is being distributed. We outline the usage of metric instrumentation in a network to gauge the bandwidth limits of the network and how to use this information to generate a model of network link utilisation. Furthermore, we show that as the link utilisation rates change in our network model, we can modify the network routing algorithms to optimise the distribution of IPTV content to end-users.

The Story Of The Beverage Can: How Cans Are Re-Used And Recycled In The Village Of Maun, Emma Frappier

Independent Study Project (ISP) Collection

For a period of three weeks I spent my days wandering the streets of Maun, talking to lodge owners, restaurants, local bars, and private waste collectors investigating the ways in which beverage cans are reused, recycled, and disposed of in Maun. Ultimately I wanted to uncover the story of the beverage can in the village of Maun. Throughout my investigation I sought to answer three important questions: how, why and by who are beverage cans recycled, how do villagers reuse beverage cans, and what are the major barriers preventing more widespread reuse and recycling of beverage cans. I conducted my …

L’Adoption De Bracharia Par Les Éleveurs Mahafaly : Un Étude Du Projet De Avsf Dans La Commune De Betioky, Michelle Fisher

Independent Study Project (ISP) Collection

Le pays de Madagascar est surtout célèbre pour sa diversité biologique et sa pauvreté économique. Quatre-vingt-dix pourcent des espèces sauvages sont endémiques (Jolly, 2008) ; d’après le « Human Development Report » le plus courant, Madagascar compte 145ième parmi les 182 pays évalués (2009). Au même temps que la population humaine se multipliait rapidement et plusieurs populations des espèces menacés diminuaient, le cheptel national est reste environs 10 million bétail pendant les deux dernières décennies (World Bank, 2003 ; Rasambanarivo et al, 1994). En 2000, l’élevage extensif de ces animaux s’est atteint à 32 millions hectares, ou 55% de la …

Creating A Category V: Conservation Perceptions And Cultural Changes In The Anjozorobe-Angavo Forest Corridor, Kate Wright

Independent Study Project (ISP) Collection

Local communities have long played an integral role in the realization of conservation goals and the success of protected areas in Madagascar. Since the appearance of human civilizations approximately 2,000 years ago (Brown 1995), the physical landscape of the island has undergone processes of adaptation to the practices of Malagasy people, while Malagasy cultures have in turn molded to fit their surroundings. The coevolution of nature and culture has produced a delicate environmental situation where human practices exploit but also conserve important natural resources, a situation that has been historically misinterpreted as intentional environmental destruction on the part of local …

Survey Of Anthropogenic Vegetation Changes On Uzi And Vundwe Islands: A Study On Deforestation And Its Implications For People And Wildlife, Lindley Mease

Independent Study Project (ISP) Collection

Background. The environmental health of Uzi Island, south of Unguja, Zanzibar, has not been well characterized and its inhabitants do not have the resources for conservation education or community management to prevent deforestation, establish sustainable resource use and preserve unique wildlife. One potential method to improve environmental conservation and economic stability is through culturally sensitive and appropriately scaled ecotourism. Methods. Vegetation and wildlife surveys were conducted to evaluate the current condition of forests, regeneration in successional habitats, the presence of endemic and endangered wildlife species, and the impact of human activity on the forests of Central Uzi and Vundwe Island. …

“Mangra”- Exploring The Organization Of An Environmental Education Curriculum In A Village Equipped For Sustainable Development, Abigail Phillips

Independent Study Project (ISP) Collection

The rapid growth of urban centers in the last century has resulted in obvious social stratification and neglect of the natural environment. Not only is the gap between rich and poor increasing, but the resources that supply urban consumption and community development are increasingly depleted without due recognition. These issues are successfully addressed in some communities by drawing example from more traditional practices of ecological management, such as water conservation and local food production. Environmental education could be utilized to aid in the relief of social issues and environmental degradation if the curriculum is specialized for each community’s circumstance. Children …

Investigating The Technical Feasibility Of Utilizing Aquifer Storage And Recovery To Supplement The Public Water Supplies In Evans Head And Ballina, Brandon Cohen

Independent Study Project (ISP) Collection

At a time when the future of fresh water resources in Australia becomes more unpredictable as a result of global climate change, it will become necessary to look for new alternative sources of fresh water. Reclaimed wastewater is an important fresh water resource that will become increasingly important. One strategy to augment the public water supply is to inject and store reclaimed water underground, then to pump it out of the aquifer and treated to drinking water standards. This is known as Aquifer Storage and Recovery (ASR) and similar schemes have been established in the United States, United Kingdom, Canada, …

Mining Globally Distributed Frequent Subgraphs In A Single Labeled Graph, Xing Jiang, Hui Xiong, Chen Wang, Ah-Hwee Tan

Research Collection School Of Computing and Information Systems

Recent years have observed increasing efforts on graph mining and many algorithms have been developed for this purpose. However, most of the existing algorithms are designed for discovering frequent subgraphs in a set of labeled graphs only. Also, the few algorithms that find frequent subgraphs in a single labeled graph typically identify subgraphs appearing regionally in the input graph. In contrast, for real-world applications, it is commonly required that the identified frequent subgraphs in a single labeled graph should also be globally distributed. This paper thus fills this crucial void by proposing a new measure, termed G-Measure, to find globally …

This free online textbook (OER more formally) is a course in undergraduate real analysis (somewhere it is called "advanced calculus"). The book is meant both for a basic course for students who do not necessarily wish to go to graduate school, but also as a more advanced course that also covers topics such as metric spaces and should prepare students for graduate study. A prerequisite for the course is a basic proof course. An advanced course could be two semesters long with some of the second-semester topics such as multivariable differential calculus, path integrals, and the multivariable integral using the …

Solvent Dependent Morphologies In Thiol-Ene Photopolymerization: A Facile Route To Synthesis Of Resorcinarene Nanocapsules, Zaharoula Marie Kalaitzis

Chemistry & Biochemistry Theses & Dissertations

Synthesis of morphologically distinct polymeric nanostructures is vital for their wide ranging applications from nanomedicine to material science. Among various polymeric nanostructures, nanocapsules in particular have attracted a lot of attention as nanoreactors and drug delivery vehicles in nanomedicine. Often, synthesis of nanocapsules is achieved by template-based approaches. A direct, template-free method for the fabrication of nanocapsules and a variety of other morphologically distinct polymeric architectures was developed. The photopolymerization of a resorcinarene thiol-ene surfactant in various solvents lead to the formation of nanocapsules, nanoparticles, fibers, distorted honeycomb-like lattices, and sheets. The progress of the polymerization reaction and the morphology …
