How To Make A Solution To A Territorial Dispute More Realistic: Taking Into Account Uncertainty, Emotions, And Step-By-Step Approach, Mahdokhat Afravi, Vladik Kreinovich

Departmental Technical Reports (CS)

In many real-life situations, it is necessary to divide a disputed territory between several interested parties. The usual way to perform this division is by using Nash's bargaining solution, i.e., by finding a partition that maximizes the product of the participants' utilities. However, this solution is based on several idealized assumptions: that we know the exact values of all the utilities, that division is performed on a purely rational basis, with no emotions involved, and that the entire decision is made once. In practice, we only know the utilities with some uncertainty, emotions are often involved, and the solution is …

Chemical Kinetics In Situations Intermediate Between Usual And High Concentrations: Fuzzy-Motivated Derivation Of The Formulas, Olga Kosheleva, Vladik Kreinovich, Laécio Carvalho Barros

Departmental Technical Reports (CS)

In the traditional chemical kinetics, the rate of each reaction A + ... + B --> ... is proportional to the product cA * ... * cB of the concentrations of all the input substances A, ..., B. For high concentrations cA, ..., cB, the reaction rate is known to be proportional to the minimum min(cA, ..., cB). In this paper, we use fuzzy-related ideas to derive the formula of the reaction rate for situations intermediate between usual and high concentrations.

Why Sparse? Fuzzy Techniques Explain Empirical Efficiency Of Sparsity-Based Data- And Image-Processing Algorithms, Fernando Cervantes, Bryan E. Usevitch, Leobardo Valera, Vladik Kreinovich

Departmental Technical Reports (CS)

In many practical applications, it turned out to be efficient to assume that the signal or an image is sparse, i.e., that when we decompose it into appropriate basic functions (e.g., sinusoids or wavelets), most of the coefficients in this decomposition will be zeros. At present, the empirical efficiency of sparsity-based techniques remains somewhat a mystery. In this paper, we show that fuzzy-related techniques can explain this empirical efficiency. A similar explanation can be obtained by using probabilistic techniques; this fact increases our confidence that our explanation is correct.

Nesting Trends Of The Green (Chelonia Mydas) And Hawksbill (Eretmochelys Imbricata) Turtles On Misali Island, Pemba, Thaowan Giorno, Megan Herrmann

Independent Study Project (ISP) Collection

Misali Island, one of the first conservation areas in Zanzibar, is considered an important nesting ground for the Green and Hawksbill turtles. This study was conducted to present results on the nesting and hatching trends on Misali Island by using data collected since 2002. Thorough statistical analyses were used on these data in order to find patterns in the nesting trends of these two species, and identify any significant differences that have occurred over the years. Overall, there has been a steady decline in the number of nesting and hatching events, but no statistically significant trends were found in terms …

The purpose for this research was to evaluate the socioemotional well-being vulnerable students and the mental health services available to them within public high school institutions. The idea is to enhance mental health and social-emotional well-being support services for vulnerable students, decreasing interruptive impact on academic performance. Research increasingly points to the link between students’ academic success and adolescent social, emotional, and behavioral health. Given that public school systems access large numbers of adolescents, they are most commonly identified as the …

Tutor, Guide, Lead: Examining The Experiences Of Peer Tutors, Kait Bouthillette

Higher Education Student Work

Peer tutoring is a form of academic support in which students who have mastered a particular subject assist peers who may be struggling in that course. While relatively little research has focused on the impact of tutoring on peer tutors, existing literature highlights the interpersonal, social, and academic skills peer tutors can gain from their experiences (Gaffney-Varma-Nelson, 2007; Loke & Chow, 2007). It is important to understand the most meaningful factors in the peer tutoring experience and the conditions that best support skills development in order to better structure programs to maximize the potential outcomes for peer tutors. The purpose …

Maya civilization developed in Mesoamerica and encompassed the Yucatan Peninsula, Guatemala, Belize, part of the Mexican states of Tabasco and Chiapas, and the western parts of Honduras and El Salvador. This civilization persisted approximately 3,000 years and was one of the most advanced of its time, possessing the only known full writing system at the time, as well as art, sophisticated architecture, and mathematical and astronomical systems. This civilization reached the apex of its power and influence during the Preclassic period, from 2000 BCE to 250 CE. Genetic variation in the pre-Hispanic Mayas from archaeological sites in the Mexican states …

Technique Comparisons For Estimating Fragility Analysis In The Central Mid-West, Kimberly Ann Walker

Masters Theses & Specialist Projects

Climate change studies and examinations of increasing sea levels and temperatures show storm intensity and frequency are increasing. As these storms are increasing in intensity and frequency, the effects of these storms must be monitored to determine the probable damages or impacts to critical infrastructure [2, 35]. These storms suddenly create new demands and requirements upon already stressed critical infrastructure sectors [1]. A combined and interdisciplinary effort must be made to identify these stresses and to mitigate any failures. This effort is needed so that the 21st Century Smart Grid is robust and resilient enough to ensure that the grid …

Applying Global Criteria To Tracking Data To Define Important Areas For Marine Conservation, Ben Lascelles, P. Taylor, M. Miller, M. Dias, S. Oppel, L. Torres, A. Hedd, M. Le Corre, R Phillips, Scott A. Shaffer, H. Weimerskirch, C. Small

Faculty Publications, Biological Sciences

Aim Enhanced management of areas important for marine biodiversity are now obligations under a range of international treaties. Tracking data provide unparalleled information on the distribution of marine taxa, but there are no agreed guidelines that ensure these data are used consistently to identify biodiversity hotspots and inform marine management decisions. Here, we develop methods to standardize the analysis of tracking data to identify sites of conservation importance at global and regional scales. Location We applied these methods to the largest available compilation of seabird tracking data, covering 60 species, collected from 55 deployment locations ranging from the poles to …

The Morphology Of Atmospheric Aerosol And Some Implications, Claudio Mazzoleni, Swarup China, Barbara Scarnato, Noopur Sharma, Janarjan Bhandari, Lynn Mazzoleni, Paulo Fialho, Cristina Facchini, Stefano Decesari, Stefania Gilardoni, Nicola Zanca

Department of Chemistry Publications

The morphology of individual atmospheric particles, including their mixing state, shape and internal structure, can have important atmospheric implications. Understanding the mechanisms leading to specific morphologies, the role of morphology in different atmospheric processes, and accounting for these details in models present considerable challenges. Several approaches are currently underway to make progress toward the resolution of these difficulties; for example, development and deployment of improved single particle analytical and observational tools, use of accurate electromagnetic models to quantitatively predict the interactions of solar radiation with single complex particles, and particle resolved models. In this presentation we will present single particle …

On Phase Ii Monitoring Of The Probability Distributions Of Univariate Continuous Processes, Partha Sarathi Mukherjee

Mathematics Faculty Publications and Presentations

Statistical process control (SPC) charts are widely used in industry for monitoring the stability of certain sequential processes like manufacturing, health care systems etc. Most SPC charts assume that the parametric form of the “in-control” process distribution F₁ is available. However, it has been demonstrated in the literature that their performances are unreliable when the pre-specified process distribution is incorrect. Moreover, most SPC charts are designed to detect any shift in mean and/or variance. In real world problems, shifts in higher moments can happen without much change in mean or variance. If we fail to detect those and let …

Predictive Formula For Electron Range Over A Large Span Of Energies, Anne C. Starley, Gregory Wilson, Lisa Montierth Phillipps, Jr Dennison

Posters

An empirical model developed by the Materials Research Group that predicts the approximate electron penetration depth—or range—of some common materials has been extended to predict the range for a broad assortment of other materials. The electron range of a material is the maximum distance electrons can travel through a material, before losing all of their incident kinetic energy. The original model used the Continuous-Slow-Down-Approximation for energy deposition in a material to develop a composite analytical formula which estimated the range from 10 MeV with an uncertainty of v, which describes the effective number of valence electrons. N_V was empirically …

Limits: Essays On The Limitations Of Science And Religion, Mario D'Amato, Thomas R. Moore, Arden Baxter, Evan Rapone, Madeleine Scott, Morgan Mcconnell, Sara Nelson

Limits

The work begins with an investigation of the mind-body problem by Arden Baxter, who argues that the mind is not reducible to the brain in practice even if it may be in theory. Evan Rapone opines that a new and concise definition of science is required, and then provides one. In an analysis of Kant’s Critique of Pure Reason, Madeleine Scott suggests that “the unthinkable will become thinkable” should we be able to transcend the limits of cognitive science by combining it with philosophical investigation. Morgan McConnell investigates the relationship between metaphors and models and concludes that the limits of …

Nutrient Cycling In The Amazon: A Comparison Of Soil Characteristics, Insects, Root Types And Decomposition Rates Between Varzea And Terra Firme Habitats In The Ecuadorian Amazon, Mira Ensley-Field

Independent Study Project (ISP) Collection

Decomposition and nutrient cycling form the basis of every ecosystem. Nutrient availability in the soil affects plant species composition, richness, and productivity. The Amazon rainforest is known for its unusually fast nutrient cycle, but many aspects lack detailed study and analysis. This comparative study carried out in the Ecuadorian Amazon had four primary objectives related to understanding the nutrient cycle in the Amazon; 1.) analyze soil characteristics, 2.) assess insect diversity in the leaf litter layer, 3.) examine root characteristics, and 4.) measure the decomposition rate between Varzea and Terra Firme habitats alongside the Rio Napo. Forty 0.25 x 0.25m …

Tracking The Elephant (Lexodonta Africana) Corridor And The Human-­‐Wildlife Conflict In Esilalei Village, A Continuation Study, Victoria Gray, Cara Cappelletti

Independent Study Project (ISP) Collection

Elephants are threatened and their habitat, wildlife corridors and overall space to roam is diminishing due to an increasing human population. As more and more space is being utilized for human development, it has begun to interfere with existing migratory corridors. This is a problem because elephants tend to destroy farmlands on their route, destroying villagers’ livelihoods, and also on occasion, may kill or hurt humans. As a result, there is a human elephant conflict. This study focused on human elephant conflict in Esilalei as well as GPS mapping evidence of elephant migration along the projected corridor between Lake Manyara …

An Assessment Of Soil Erosion On Pemba Island Using The Universal Soil Loss Equation, Emily Gillispie

Independent Study Project (ISP) Collection

Healthy soil is necessary for maintaining agricultural productivity, which is the basis of the economy on Pemba Island, Tanzania. Soil erosion is a notable concern for subsidence-farming villages, as it reduces the agricultural potential of farmland through the loss of nutrients, organic matter, and depth of quality growing soil (Georhing, 2009). The island of Pemba is the perfect case study for soil erosion, as their economy is largely based in agriculture, and the combined hilly topography and monsoonal climate make it highly susceptible to soil erosion. Yet, Pemba’s main cash crops are clove and fruit trees, which have potential to …

Water Quality In Relation To Land-Use Of The Upper 62.8 Kilometers Of The Santa Maria River, Santa Fe, Veraguas Using Benthic Macroinvertebrates As Indicators, Charlotte Steeves

Independent Study Project (ISP) Collection

The Santa Maria River spans approximately 148 kilometers from its headwaters in the district of Santa Fe, Veraguas to its mouth at the Golfo de Parita, Herrera. The objective of this study was to determine the relation between land-use and site-specific water quality using benthic macroinvertebrates as indicators. To assess water quality of the upper portion of the Santa Maria River, benthic macroinvertebrates were collected at 10 points within the river from Santa Fe national park to the town of San Francisco, approximately 62.8 kilometers. This study examines how land-use near the banks of the Santa Maria River effect water …

Comparison Of Growth Rates In Two Captive Bred Species Of Atelopus (Anura; Bufonidae), At El Valle Amphibian Conservation Center, Cecile Avery

Independent Study Project (ISP) Collection

Since their evolution, amphibians have managed to survive four mass extinctions. But today’s amphibians are now facing severe decline due to a plethora of causes including habitat destruction, climate change, pathogens, and pollution. Of all the possible causes of decline and extinction of amphibian populations, one of the most startling has been the effect of Batrachochytrium dendrobatidis (Bd), or chytrid fungus. It was decided that rapid action was needed to preserve the amphibian populations in the area, since it was clear that current in situ conservation methods were ineffective against Bd. EVACC, the El Valle Amphibian Conservation Center, was created …

Chemical And Physical Characteristics Of Rivers Above And Below Four Hydroelectric Power Facilities In The Chiriquí Viejo And Chico Watersheds Of Chiriquí, Panama, Tricia Light

Independent Study Project (ISP) Collection

The advance of anthropogenic climate change and human energy use has sparked unprecedented international interest and investment in fossil fuel free energy sources such as hydroelectric power. Extensive construction of hydroelectric power facilities has occurred in Panama in recent years, particularly in the westernmost Chiriquí province. Hydroelectric power, especially that generated by relatively small facilities, is generally thought to be a “clean” alternative energy source with few negative environmental consequences. Some evidence suggests, however, that even small facilities can have significant ecological impacts on rivers. This study investigated river properties above and below four small hydroelectric facilities on the Chiriquí …

Cerebral Malaria: An Unusual Case Of Central Diabetes Insipidus, Resmi Premji, Nira Roopnarinesingh, Joshua Cohen, Sabyasachi Sen

Medicine Faculty Publications

Central diabetes insipidus is an uncommon feature of malaria. A previously healthy 72-year-old man presented with fever, rigors, and altered mental status after a recent trip to Liberia, a country known for endemic falciparum malaria. Investigations confirmed plasmodium falciparum parasitemia. Within one week after admission, the serum sodium rose to 166 mEq/L and the urine output increased to 7 liters/day. Other labs were notable for a high serum osmolality, low urine osmolality, and low urine specific gravity. The hypernatremia did not respond to hypotonic fluids. Diabetes insipidus was suspected and parenteral desmopressin was started with a prompt decrease in urinary …

Beauty In Snowflakes: Complexity And Visual Aesthetics, Olivia C. Adkins

Masters Theses & Specialist Projects

Experimental aesthetics research has been conducted since the nineteenth century. Interestingly, however, few studies have examined the perceived beauty of naturally shaped objects. In the current experiment, 204 participants were presented with a set of ten snowflake silhouettes that varied in complexity (perimeter relative to area); they were similarly presented with ten randomly-shaped, computer-generated, solid objects that also varied in complexity. For each stimulus set, the participants selected the single snowflake or object that was the most beautiful (Fechner’s method of choice). The results for the solid objects replicated the findings of earlier research: the most and least complex objects …

Religion As A Chinese Cultural Component: Culture In The Chinese Taoist Association And Confucius Institute, John D. Abercrombie

Masters Theses & Specialist Projects

This thesis examines the role of the cultural discourse on the indigenous religious traditions of China and their place within an officially sanctioned construction of Chinese culture. It starts by examining the concept of culture as it developed in the modern era, its place within the construction of national identities, and the marginalizing effects this has on certain members of national populations. Next it turns to the development of the cultural discourse within China from the mid-1800s to the Cultural Revolution, highlighting the social and legal transformations as they restricted and reframed the practice and articulation of religious traditions in …

Optimal Motivation And Cognitive Load For Enhanced Math Performance, Manooch S. Saeedi

Masters Theses & Specialist Projects

Educational research has a long history of investigating factors that are linked to improved academic performance. Here I examined research on three factors that impact academic performance—working memory (WM), cognitive load, and motivation. Although each of these factors were known to impact academic performance, there were no studies that examined the combined effect of these three factors on performance. The current study attempted to examine the potential connections between these factors, and their collective impact on strategies for learning in the context of math performance. Experiment 1 tested the impact of WM, cognitive load, and motivation for a math task …
