Challenges With Large Transverse Momentum In Semi-Inclusive Deeply Inelastic Scattering, J. O. Gonzalez-Hernandez, T. C. Rogers, N. Sato, B. Wang Dec 2018

Challenges With Large Transverse Momentum In Semi-Inclusive Deeply Inelastic Scattering, J. O. Gonzalez-Hernandez, T. C. Rogers, N. Sato, B. Wang

Physics Faculty Publications

We survey the current phenomenological status of semi-inclusive deeply inelastic scattering at moderate hard scales and in the limit of very large transverse momentum. As the transverse momentum becomes comparable to or larger than the overall hard scale, the differential cross sections should be calculable with fixed order perturbative QCD (pQCD) methods, while small transverse momentum (transverse-momentum-dependent factorization) approximations should eventually break down. We find large disagreement between HERMES and COMPASS data and fixed order calculations done with modern parton densities, even in regions of kinematics where such calculations should be expected to be very accurate. Possible interpretations are suggested.


Protecting Privacy Of Data In The Internet Of Things With Policy Enforcement Fog Module, Abduljaleel Al-Hasnawi Dec 2018

Protecting Privacy Of Data In The Internet Of Things With Policy Enforcement Fog Module, Abduljaleel Al-Hasnawi

Dissertations

The growth of IoT applications has resulted in generating massive volumes of data about people and their surroundings. Significant portions of these data are sensitive since they reflect peoples' behaviors, interests, lifestyles, etc. Protecting sensitive IoT data from privacy violations is a challenge since these data need to be handled by public networks, servers and clouds, most of which are untrusted parties for data owners. In this study, a solution called Policy Enforcement Fog Module (PEFM) is proposed for protecting sensitive IoT data. The primary task of the PEFM solution is mandatory enforcement of privacy polices for sensitive IoT data-whenever …

Fully Convolutional Neural Networks For Pixel Classification In Historical Document Images, Seth Andrew Stewart Oct 2018

Fully Convolutional Neural Networks For Pixel Classification In Historical Document Images, Seth Andrew Stewart

Theses and Dissertations

We use a Fully Convolutional Neural Network (FCNN) to classify pixels in historical document images, enabling the extraction of high-quality, pixel-precise and semantically consistent layers of masked content. We also analyze a dataset of hand-labeled historical form images of unprecedented detail and complexity. The semantic categories we consider in this new dataset include handwriting, machine-printed text, dotted and solid lines, and stamps. Segmentation of document images into distinct layers allows handwriting, machine print, and other content to be processed and recognized discriminatively, and therefore more intelligently than might be possible with content-unaware methods. We show that an efficient FCNN with …

Polynomial Fitting, R. Steven Turley Sep 2018

Polynomial Fitting, R. Steven Turley

Faculty Publications

This article reviews the theory and some good practice for fitting polynomials to data. I show by theory and example why fitting using a basis of orthogonal polynomials rather than monomials is desirable. I also show how to scale the independent variable for a more stable fit. I also demonstrate how to compute the uncertainty in the fit parameters. Finally, I discuss regression analysis: how to determine whether adding an additional term to the fit is justified.


Implementing The Use Of Personal Activity Data In An Introductory Statistics Course, Lacy Christensen Aug 2018

Implementing The Use Of Personal Activity Data In An Introductory Statistics Course, Lacy Christensen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Integrating real data into a classroom is one of the recommendations in the Guidelines for Assessment and Instruction in Statistics Education (GAISE) college report which lays out guidelines for an introductory statistics course (Committee, GAISE College Report ASA Revision, 2016). In order to assess the effect of using real data in a classroom, the students received physical activity trackers to wear during an undergraduate introductory statistics course taught in the summer. This tracker, a Fitbit, enabled students to monitor and record their steps, calories, and active time throughout the class. Collecting personal activity data (PAD) creates a large database which …


From Data To Decisions: Navigating The “So What?” And “What’S Next?” Conversation Around Nearshore Data, Dawn Spilsbury Pucci Apr 2018

From Data To Decisions: Navigating The “So What?” And “What’S Next?” Conversation Around Nearshore Data, Dawn Spilsbury Pucci

Salish Sea Ecosystem Conference

Ever wonder what happens to all those data being collected? In Island County, we are fortunate to be the focus of a plethora of data collection efforts. We have comprehensive nearshore assessments that describe where our habitats are and how those habitats are built. We have habitat assessments that are a collaborative effort between citizen science groups and state agencies. We have long-term status and trends data sets on intertidal habitats and presence for a few specific species. We have a high resolution shoreline armor dataset and we have a predictive probability model for coastal flood risk. But what do …

Development Of An Interactive Web Map To Visualize A Complex Dataset, Lisa Ferrier

Salish Sea Ecosystem Conference

The Washington State Department of Natural Resources (DNR) is steward to 2.6 million acres of state-owned aquatic lands. As part of its management responsibilities, DNR’s Submerged Vegetation Monitoring Program (SVMP) documents occurrences of seagrass throughout greater Puget Sound. Seagrasses are recognized globally as a sensitive indicator of water quality while providing productive, critical habitat utilized by many fish, bird and invertebrate species. The SVMP has been conducting seagrass surveys in Puget Sound, using underwater video, since 2000. Video is reviewed, classified for presence/absence, and ultimately used to characterize abundance, distribution and change in seagrass at local, regional, and sound-wide scales. …

Students’ Interpretations Of Categorical Data Using Dynamic Graphical Representations, Adam Eide Jan 2018

Students’ Interpretations Of Categorical Data Using Dynamic Graphical Representations, Adam Eide

Master's Theses and Doctoral Dissertations

Statistical association is an important concept in statistics. An exploratory study examined how students reason about statistical association utilizing graphical representations constructed with CODAP, a dynamic statistical graphing software. Task-based interviews were conducted with three 6th grade students prior to formal instruction. Students’ conceptions of a statistical relationship, proportional reasoning skill level, ability to interpret bivariate categorical graphs (particularly segmented bar graphs and two-way binned plots), and ability to identify association of two categorical variables were all investigated through interview tasks and responses to inquiry. Students were found to have developing proportional reasoning skills and struggled to correctly define and …
