A series of experiments were conducted in vivo using Yucatan miniature pigs (Sus scrofa domestica) to determine thermal damage thresholds to the skin from 1319-nm continuous-wave Nd:YAG laser irradiation. Experiments employed exposure durations of 0.25, 1.0, 2.5, and 10 s and beam diameters of ∼0.6 and 1 cm. Thermal imagery data provided a time-dependent surface temperature response from the laser. A damage endpoint of fifty percent probability of a minimally visible effect was used to determine threshold for damage at 1 and 24 h postexposure. Predicted thermal response and damage thresholds are compared with a numerical model of opticalthermal interaction. …

Infrastructure Redesign And Instructional Reform In Mathematics: Formal Structure And Teacher Leadership, Megan Hopkins, James P. Spillane, Paula M. Jakopovic, Ruth M. Heaton

Teacher Education Faculty Publications

Designing infrastructures to support instruction remains a challenge in educational reform. This article reports on a study of one school system's efforts to redesign its infrastructure for mathematics instruction by promoting teacher leadership. Using social network and interview data from 12 elementary schools, we explore how the district's infrastructure redesign efforts were internally coherent with and built upon existing infrastructure components. We then explore relations between infrastructure and school practice as captured in the instructional advice- and information-seeking interactions among school staff, finding that teacher leaders emerged as central actors and brokers of advice and information about mathematics within and …

Merging And Creating Culturally Relevant Pedagogy In Public Schools, Sunni Ali, Ryan Murphy

Educational Inquiry and Curriculum Studies Faculty Publications

During the last fifty years, numerous individuals have sought new strategies for students, such as African Americans, whom the public schools have historically underserved. Not only are some parents of these students seeking change, but also researchers, politicians, and local groups. Nevertheless, it is clear that these efforts have posed several dilemmas, which (a) limit the voice and personal choice of learners, (b) standardize the value of learning, and (c) connote a hegemonic discourse. Therefore, this Best Practices essay is based on the theory that a culturally value-driven framework (CVD) of learning will allow African Americans and other students of …

Effects Of Sequence Context On The Binding Of Tryptophan-Containing Peptides By The Cucurbit[8]Uril-Methyl Viologen Complex, Omar A. Ali, Eric M. Olson, Adam R. Urbach

Chemistry Faculty Research

This paper describes a novel assay for measuring the relative extent of peptide binding in a large parallel format and the use of this assay to explore the effects of sequence context on the binding of tryptophan (Trp)-containing peptides by the synthetic receptor comprising the noncovalent complex between cucurbit[8]uril and methyl viologen (i.e. Q8√MV). The extent of quenching of Trp fluorescence upon binding to Q8√MV was used to measure the relative extent of binding and thus the relative affinities of 104 Trp-containing peptides, in parallel, using a fluorescence plate reader. This study resulted in the remarkable observation that the identity …

"And"- And "Or"-Operations For "Double", "Triple", Etc. Fuzzy Sets, Hung T. Nguyen, Vladik Kreinovich, Olga Kosheleva

Departmental Technical Reports (CS)

In the traditional fuzzy logic, the expert's degree of confidence d(A & B) in a complex statement A & B (or A\/B) is uniquely determined by his/her degrees of confidence d(A) and d(B) in the statements A and B, as f_&(d(A),d(B)) for an appropriate "and"-operation (t-norm). In practice, for the same degrees d(A) and d(B), we may have different degrees d(A & B) depending on the relation between A and B. The best way to take this relation into account is to explicitly elicit the corresponding degrees d(A & B) and d(A\/B), i.e., to come up with "double" …

Towards Designing Optimal Individualized Placement Tests, Octavio Lerma, Olga Kosheleva, Shahnaz Shahbazova, Vladik Kreinovich

Departmental Technical Reports (CS)

To find the current level of a student's knowledge, we use a sequence of problems of increasing complexity; if a student can solve a problem, the system generates a more complex one; if a student cannot solve a problem, the system generates an easier one. To find a proper testing scheme, we must take into account that every time a student cannot solve a problem, he/she gets discouraged. To take this into account, we define an overall effect on a student by combining "positive" and "negative" problems with different weights, and we design a testing scheme which minimizes this effect.

Why 20? Why 40? A Possible Explanation Of A Special Role Of 20 And 40 In Traditional Number Systems, Olga Kosheleva, Vladik Kreinovich

Departmental Technical Reports (CS)

Both historical and linguistic evidence shows that numbers 20 and 40 played a special role in many traditional numerical systems. The fact that, e.g., the same number 20 appears in unrelated cultures such as Romans and Mayans is an indication that this number must have a general explanation related to human experience. In this paper, we provide a possible explanation of 20 and 40 along these lines: namely, we show that these numbers can be identified as the smallest sample sizes for which we can extract statistically significant information.

Why Triangular Membership Functions Work Well In F-Transform: A Theoretical Explanation, Jaime Nava, Vladik Kreinovich

Departmental Technical Reports (CS)

In many practical applications, it is useful to represent a signal or an image by its average values on several fuzzy sets. The corresponding {\em F-transform} technique has many useful applications in signal and image processing. In principle, we can use different membership functions. Somewhat surprisingly, in many applications, the best results occur when we use triangular membership functions. In this paper, we provide a possible theoretical explanation for this empirical phenomenon.

Causal Strategic Inference In Social And Economic Networks, Mohammad Tanvir Irfan

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Who are the most influential senators in Congress? Is there a small coalition of senators who are influential enough to prevent filibusters? In a different setting of microfinance markets, can we predict the effects of interventions to help policy makers? In order to pursue such diverse questions, we propose causal strategic inference, a game-theoretic counterpart of causal probabilistic inference. Using this general framework, we study two different sets of problems, broadly on social networks and networked microfinance economies. In the first study, we introduce a new approach to the study of influence that captures the strategic aspects of the complex …

Machine Learning, Evolutionary Algorithms, And The Inference Of Mathematical Truths, Asher Hensley

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

In this thesis we set out to find whether the true data generating formula behind a set of data points can be automatically inferred from the data points alone. We start with the topic of machine learning and quickly realize that black box models can only approximate the real world which creates the motivation to move on to evolutionary algorithms as a vehicle to implement symbolic regression. Through a series of experiments we discover that the mean-squared error cost function is easily fooled by decoy solutions and is unable to make use of all the information presented in the training …

Generation Of Customized Time Domain Fir Filter Hardware, Yujie Wu

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Although finite impulse response (FIR) filtering is a well-known technique, it is still difficult to implement efficiently as hardware because the designer must choose from many application-specific design options, and it is difficult to choose those that best fit the requirements of the system. This thesis describes two design and simulation tools which enable easy implementation and optimization of time-domain FIR filters. The first generates hardware (as synthesizable Verilog) for a designer-specified FIR filter and the second provides a fixed-point simulation environment for the design space (using MATLAB). Both tools are customized based on the user's choices across a parameterized …

Organic photovoltaic (OPV) cells are advanced, newly emerging technologies that are lightweight, mechanically flexible devices with highthroughput processes from low cost material in a variety of colors. Rathnayake et al. of Western Kentucky University have developed a nanostructure-based OPV cell. Presented in this thesis is a model and simulation of a generalized PV powered system that can predict the performance of solar arrays in various environmental conditions. The simulation has been carried out in Matlab/Simulink, and upon entering the cell’s parameters, it provides key electrical characteristics such as the cell’s I-V curve and efficiency information. The total system that is …

Conscious Reconstruction: The Effects Of Second Language Acquisition On Self-Perception Of Gender Identity, Geneva Ged

Masters Theses & Specialist Projects

Gender interacts with other facets of English Language Learners’ social identity like race and ethnicity to guide their learning experiences, desires, and outcomes; however, much of traditional Teaching English as a Second Language (TESOL) research has focused on how motivation and language learning beliefs differ between male and female English as a Second Language/English as a Foreign Language (ESL/EFL) students with the intent to identify difference, if it exists. English Language Learners who are studying abroad or who have immigrated to the United States have already established a gender identity influenced and created by their experiences in their first language …

Global Digital Elevation Model Accuracy Assessment In The Himalaya, Nepal, Luke G. Miles

Masters Theses & Specialist Projects

Digital Elevation Models (DEMs) are digital representations of surface topography or terrain. Collection of DEM data can be done directly through surveying and taking ground control point (GCP) data in the field or indirectly with remote sensing using a variety of techniques. The accuracies of DEM data can be problematic, especially in rugged terrain or when differing data acquisition techniques are combined. For the present study, ground data were taken in various protected areas in the mountainous regions of Nepal. Elevation, slope, and aspect were measured at nearly 2000 locations. These ground data were imported into a Geographic Information System …

Cinema In The Digital Age: A Rebuttal To Lev Manovich, Barbara Cail

Philosophy

In his book The Language of New Media, Lev Manovich claims the index is an ontological condition of cinema. Manovich asserts digital cinema can never be indexical and therefore has fundamentally altered the very nature of cinema, reducing it to a form of animation. This paper offers a refutation of Manovich’s redefinition of cinema, showing that digital cinema can be indexical, but indexicality is not an ontological condition of cinema.

Pisa 2012 : How Australia Measures Up : The Pisa 2012 Assessment Of Students’ Mathematical, Scientific And Reading Literacy, Sue Thomson, Lisa De Bortoli, Sarah Buckley

OECD Programme for International Student Assessment (PISA) Australia

PISA seeks to measure how well young adults at age 15 (and, therefore, near the end of compulsory schooling in most participating education systems) are prepared to use their knowledge and skills in particular areas to meet real-life challenges. PISA’s orientation reflects a change in the goals and objectives of curricula, which increasingly address how well students are able to apply what they learn at school. This report presents the results of the PISA 2012 assessment for Australia. It presents the results for Australia as a whole, for the Australian jurisdictions and (where relevant) for the other participants in the …

Identification Of Disufide Bond Formation Between Mitoneet And Glutamate Dehydrogenase 1, Morgan E. Roberts, Jacquelyn P. Crail, Megan M. Laffoon, William G. Fernandez, Michael A. Menze, Mary E. Konkle

Faculty Research & Creative Activity

MitoNEET is a protein that was identified as a drug target for diabetes, but its cellular function as well as its role in diabetes remains elusive. Protein pull-down experiments identified glutamate dehydrogenase 1 (GDH1) as a potential binding partner. GDH1 is a key metabolic enzyme with emerging roles in insulin regulation. MitoNEET forms a covalent complex with GDH1 through disulfide bond formation and acts as an activator. Proteomic analysis identified the specific cysteine residues that participate in the disulfide bond. This is the first report that effectively links mitoNEET to activation of the insulin regulator GDH1.

Census And Mapping Of Chorro Creek Bog Thistle In Reservoir Canyon, San Luis Obispo, Ca, Tyler Michael Lutz

Biological Sciences

Chorro Creek bog thistle (Cirsium fontinale var. obispoense) is a federally endangered variety of Fountain thistle endemic to western San Luis Obispo County. The U.S. Fish and Wildlife Service knows of nineteen populations, many with multiple colonies. A population was discovered in the Reservoir Canyon Natural Reserve in 2001, but has not been monitored or described since the time of its discovery. In fall of 2013, a census of the population was performed, the four colonies were mapped, and a floristic survey was conducted. A field experiment was initiated to determine if reducing the riparian canopy coverage can …

Geoelectrical Detection Of Water Table Depth At Two Locations In The Los Osos Groundwater Basin, Hallie A. Douglas

Natural Resources Management and Environmental Sciences

The city of Los Osos sits on top of a coastal groundwater aquifer which is the sole supplier of all its residential, agricultural, and industrial water needs. Lacking a sewer system, the upper aquifer became progressively contaminated with nitrates over several decades. Groundwater pumping eventually shifted to the lower aquifer, however seawater intrusion of the lower aquifer caused by over-pumping has further degraded water quality. The Los Osos groundwater basin provides an excellent field region to examine the utility of geophysical methods for characterizing aquifer structure. In this study shallow (<20 >m) electrical resistivity imaging methods were performed at two …
