The Application Of Tomographic Reconstruction Techniques To Ill-Conditioned Inverse Problems In Atmospheric Science And Biomedical Imaging, Vern Philip Hart Ii

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Tomography is an imaging technique in which 3D models of objects are created from several 2D projections viewed at different angles. When the number of available projections is limited, the resulting data are said to be sparse. This restriction is often a direct result of the imaging geometry used to acquire the data. One-sided views and a small number of receivers can reduce the range of available projections, which makes the object more difficult to reconstruct. Approximate solutions to difficult imaging problems can be obtained using a class of iterative algorithms known as the algebraic reconstruction techniques (ARTs). The presented …

Towards An Art And Science Of Decision Aiding For Water Management And Planning: A Participatory Modelling Process, Katherine A. Daniell, Ian White, Nils Ferrand, Alexis Tsoukias, Stewart Burn, Pascal Perez

Professor Pascal Perez

Planning and management of water resources are faced with increasingly high levels of complexity, uncertainty and conflict. Traditional technical and top-down management strategies have proved inadequate, forcing a move to more "integrated" forms of management, planning and decision making that can include stakeholders and communities, as well as technical experts and policy makers. These integrated forms of management require not only good technical or scientific ability, but a range of "art-like" skills including communication, creativity and the capacity to acknowledge and integrate diverse points of view. However, processes designed to aid such inter-organisational or multi-stakeholder decisionmaking are rare and in …

Embracing Social Uncertainties With Complex Systems Science, Pascal Perez

Professor Pascal Perez

Human ecosystems are real-life systems characterized by very strong and longterm interactions between human communities and their environment; as such they constitute an expansion of the ecological concept of ecosystem. According to Stepp and colleagues (2003), human ecosystems not only process matter and energy flows, but - and more specifically - information flows as well. Therefore, they display very specific characteristics due to our ability to communicate and learn from others, creating the conditions for co-evolutionary processes in which chance lends a hand to necessity. Bradbury (2006) argues that, until recently, human beings had been able to adapt to changes …

Transition In The Fractal Geometry Of Arctic Melt Ponds, C. Hohenegger, B. Alali, K. R. Steffen, D. K. Perovich, K. M. Golden

Dartmouth Scholarship

During the Arctic melt season, the sea ice surface undergoes a remarkable transformation from vast expanses of snow covered ice to complex mosaics of ice and melt ponds. Sea ice albedo, a key parameter in climate modeling, is determined by the complex evolution of melt pond configurations. In fact, ice–albedo feedback has played a major role in the recent declines of the summer Arctic sea ice pack. However, understanding melt pond evolution remains a significant challenge to improving climate projections. By analyzing area–perimeter data from hundreds of thousands of melt ponds, we find here an unexpected separation of scales, where …

Place Making: Mapping Culture, Creating Places: Collisions Of Science And Art, Christopher R. Gibson

Chris Gibson

The arts have much to offer the reinvention of places: generating new forms of employment in cultural work, contributing to public culture through festivals and events, and appropriating spaces in the built environments of our cities and towns for artistic expression. Filtering artistic attempts to re-make places are three key competing pressures: first, the demands of regional development managers, treasury bureaucrats and council general managers for accountability, ‘hard data’ and measurable outcomes; second, desires of local residents, non-profit organisations and community development specialists to use the arts as a means to promote social inclusion and recognition of social difference; and …

A Meta-Analysis Of Alternative Water Sources, Katie Colton

Honors Projects in History and Social Sciences

Roughly one half of the Earth’s population suffers from shortage or lack of clean water. While many innovations and products have been created to address this Global Water Crisis, no comparisons have been done as to which innovations and products are the best overall choice for philanthropic investment. The crisis can be broken down into three specific crises including the transportation crisis, the access crisis, and the sanitation crisis. The study examined fifteen innovations and products, targeted to address the three crises to determine which innovation in each group is the overall smart investment. Pulse tool was used to create …

Experimental Studies Of The Nacs 53Π0 And A3Σ+ States, Seth T. Ashman, B. Mcgeehan, C. M. Wolfe, C. Faust, K. Richter

Engineering & Physics Faculty Publications

We report high resolution measurements of 372 NaCs 53Π0(v, J) ro-vibrational level energies in the range 0 ≤ v ≤ 22. The data have been used to construct NaCs 53Π0 potential energy curves using the Rydberg–Klein-Rees and inverted perturbation approximation methods. Bound-free 53Π0(v, J) → 1(a)3Σ+ emission has also been measured, and is used to determine the repulsive wall of the 1(a)3Σ+ state and the 53Π0 → 1(a)3Σ+ relative transition dipole moment function. Hyperfine structure in the 53Π0 state has not been observed in this experiment. This null result is explained using a simple vector coupling model.

Confirmation And Investigation Of Higher Science Curiosity In Juarez Middle School Students Compared To Their Peers In El Paso, Texas, Karla Carmona Miranda

Open Access Theses & Dissertations

In the last 20 years attitudes towards science and science classes in K-12 education have been an important topic of investigation due to the decreasing number of students choosing Science, Technology, Engineering and Math (STEM) related careers, and the increasing need for STEM prepared workers to cover the job demands of the future. The purpose of this study is to confirm a previously measured difference in scientific curiosity between middle school students in El Paso and in Ciudad Juarez, and to collect additional data that might tell us what the possible factors or reasons for this difference are. Our sample …

Science Or Experience; What Is More Relevant ?, Kenneth Fowle, Hadyn Green

Research outputs 2012

It is very important that when we use science to determine the validity of evidence or information that it is done in a manner that is acceptable to the scientific community and the legal community, but what happens when “experience” is used. The use of forensic practitioners to provide „expert‟ evidence and opinion must meet the Daubert/Frye and now Kumho tests. This paper will endeavour to demonstrate .what is best for a practitioner to have and what does the judiciary require for „expert‟ evidence to be accepted? Science and/or Experience, what is more relevant? Evidence and the Courts depend upon …

Educational Looping And Retention In The Middle School Setting, Mary Elizabeth Feighery

LSU Master's Theses

Educational looping is an educational method where teachers remain with the same core group of students over multiple academic years. The current research on this topic shows a strong positive correlation between the effects of looping and the growth of personal relationships between students and teachers, but neglects to examine the connection between looping and student educational growth. This paper explores the relationship between looping and academic gains, as well as between looping and retention of content material over time. This paper explores both the relationship between looping and academic gains and between looping and retention of content material, and …
