Exploiting Memristors For Compressive Sensing Applications, Fengyu Qian

Doctoral Dissertations

The amount of sensory signal is increasing dramatically as we’re stepping into the era of Internet of Things (IoT). Compressive Sensing (CS), feature as Sub-Nyquist sampling rate and low complexity sensing architectures, is very promising for these kinds of applications where resources are restricted. Through applying this novel compression technology, data size of sensory signals are largely compressed such that it is very efficient within the signal processing, data transmitting and storage processes. Compared to conventional codec method, CS technique requires less hardware resources and achieve lower power consumption within sensor nodes.

However, there are several bottle-necks of existing compressive …

Analysis Of The Duration And Energy Consumption Of Aes Algorithms On A Contiki-Based Iot Device, Brandon Tsao

Computer Science and Engineering Master's Theses

With the growing prevalence of the Internet of Things, securing the sheer abundance of devices is critical. The current IoT and security landscapes lack empirical metrics on encryption algorithm implementations that are optimized for constrained devices, such as encryption/decryption duration and energy consumption. In this paper, we achieve two things. First, we survey for optimized implementations of symmetric encryption algorithms. Seconds, we study the performance of various symmetric encryption algorithms on a Contiki-based IoT device. This paper provides encryption and decryption durations and energy consumption results on three implementations of AES: TinyAES, B-Con’s AES, and Contiki’s own built-in AES. In …

Retrodirective Phased Array Antenna For Nanosatellites, Justin W. Long

Engineering

This thesis presents a S-band phased array antenna for CubeSat applications. Existing state-of the-art high gain antenna systems are not well suited to the majority of CubeSats, those that fall within the 1U (10 cm x 10 cm x 10 cm) to 3U (10 cm x 10 cm x 30 cm) size ranges and in Low Earth Orbit (LEO). The system presented in this thesis is designed specifically to meet the needs of those satellites. This system is designed to fit on the 1U face (10 cm x 10 cm) of a CubeSat and requires no deployables. The use of …

Flying The Frontier: A Case Study Comparison Of Newspaper Coverage Of Early Northern Plane Crashes, Leanna Prax Williams

Arctic and Northern Studies

From the early days of Alaskan aviation beginning in 1923, stories about Alaskan bush pilots leapt from newspaper pages, captivating readers and selling papers. These newspaper stories, along with magazine articles and other popular culture media accounts, portrayed pilots as pioneers, cowboys and brave adventurers, and referred to Alaska in terms heavily laden with American frontier imagery, a trend that persisted in Alaska but faded elsewhere. What did newspaper reports convey about the lives and deaths of these aviators and their relationships to Alaska and the frontier? How has the portrayal of these early Alaskan pilots in ways that perpetuated …

Attitudes Towards Teaching Computational Thinking And Computer Science: Insights From Educator Interviews And Focus Groups, Jorge Valenzuela

Journal of Computer Science Integration

In the last three years, integration of both computational thinking (CT) and computer science (CS) into K-12 instruction has become a focus of many schools throughout the Commonwealth of Virginia and the United States. With this new widespread demand, educational leaders and educators are focusing efforts on understanding the core concepts and practices of CT and CS, looking for logical connections for integrating across curriculum, and seeking strategies for implementing a wide variety of educational technology tools (apps and devices). This phenomenological research study was designed to gather depth information from 14 K-16 educators through both semi-structured interviews and two …

The Missing Mirror: A Critical Content Analysis Of Multicultural Children's Literature With Black Male Characters, Wendy Harris

Doctor of Education in Educational Leadership Dissertations

Education in America is facing many challenges, such as the adoption of common core standards and the demand for highly qualified teachers (Darling-Hammond, 2010). Further, the achievement gap lingers on, with Black males often performing poorly on national assessments of reading proficiency (Tatum, 2005). Although Black males are highly literate, they may feel alienated from traditional school systems and classroom reading selections (Kirkland, 2013). One of the most effective strategies for teachers to bridge the gap in reading is to inspire Black males to get engaged with their books and read for longer periods of time. However, children are more …

Replication Study: Biomechanical Remodeling Of The Microenvironment By Stromal Caveolin-1 Favors Tumor Invasion And Metastasis, Mee Rie Sheen, Jennifer L. Fields, Brian Northan, Judith Lacoste, Lay-Hong Ang, Steven Fiering

Dartmouth Scholarship

As part of the Reproducibility Project: Cancer Biology we published a Registered Report (Fiering et al., 2015) that described how we intended to replicate selected experiments from the paper ‘Biomechanical remodeling of the microenvironment by stromal caveolin-1 favors tumor invasion and metastasis’ (Goetz et al., 2011). Here we report the results. Primary mouse embryonic fibroblasts (pMEFs) expressing caveolin 1 (Cav1WT) demonstrated increased extracellular matrix remodeling in vitro compared to Cav1 deficient (Cav1KO) pMEFs, similar to the original study (Goetz et al., 2011). In vivo, we found higher levels of intratumoral stroma remodeling, determined by fibronectin fiber orientation, in tumors …

Single-cell RNA-seq is a powerful tool in decoding the heterogeneity in complex tissues by generating transcriptomic profiles of the individual cell. Here, we report a single-nuclei RNA-seq (snRNA-seq) transcriptomic study on human retinal tissue, which is composed of multiple cell types with distinct functions. Six samples from three healthy donors are profiled and high-quality RNA-seq data is obtained for 5873 single nuclei. All major retinal cell types are observed and marker genes for each cell type are identified. The gene expression of the macular and peripheral retina is compared to each other at cell-type level. Furthermore, our dataset shows an …

Measuring Person–Job Fit And Career Paths Of Distance Learning Librarians, Jennifer J. Rundels, Anne Marie Casey

Publications

While person–job fit has been used to determine satisfaction in many professions, no research has been done among distance learning librarians. This study investigates person–job fit among librarians with primary distance learning responsibility compared to librarians with some distance learning responsibility and examines whether a common career path exists among the two groups. Responses indicate that librarians who work primarily in distance learning perceive a slightly better fit with their positions and the work itself while those with some distance learning responsibility experience a slightly better fit within their library organizations. Career advancement is a common motivator for both groups.

Human-Infrastructure Interfaces (Hii) Enabled Using Augmented Reality (Ar), Dilendra Maharjan

Civil Engineering ETDs

The modern industrial society is built upon the productivity of advanced computing and agile machines assisting the human workforce to perform their tasks more effectively, accurately and efficiently. The industrial revolution termed as "Industry 4.0" is based on the intelligence of machines working with humans in a collaborative work-space. Contrarily, infrastructure management has relied on the human for making day to day decisions. New emerging technologies can assist during infrastructure inspections, to quantify structural condition with more objective data. However, today's’ owners agree in trusting the inspector's decision in the field over data collected with sensors. If data collected in …

A Mixed Methods Evaluation Of Patient And Provider Perspectives Of Chronic Illness Management Following Kidney Transplantation, Catherine Kelley Pantik

Theses and Dissertations (ETD)

Introduction: Inconsistent, fragmented care coordination in kidney transplant recipients (KTRs)—whose management requires long-term, complex care, and multiple handoffs among providers—has been shown to result in suboptimal care and higher costs. In order to move forward in improving long-term outcomes, it is necessary to fully assess current practice patterns with appropriate measures. With a full and accurate picture of how elements of the management plan influence both KTR and the health care provider (HCP), it will be possible to implement changes that improve long-term outcomes.Methods: The Chronic Care Model (CCM) was the framework for the study. A mixed method research approach …

How The Atacama Skeleton Might Advance Discussion Of Responsible Conduct Of Research Responsibilities, Thomas May, Mariko Nakano-Okuno

Human Biology Open Access Pre-Prints

Controversies resulting from genetic testing on skeletal remains of disputed stewardship raise important questions about obligations inherent on genetic researchers to assure ethical chain of custody. In this paper, we analyze and evaluate several proposed positions on whether such research should be published. Following jurisprudential standards for legitimate regulatory systems, we argue that responsible conduct of research requires reasonable attention to chain of custody, but cannot require guarantees, particularly in cases of ancient remains.

Prudhoe Bay West End Gas Lift Supply Optimization, Irwin Chou

Engineering

The western extension of Alaska's Prudhoe Bay, known collectively as Eileen West End (EWE), operates under a gas lift pressure supply constraint. This constraint is largely contributed by two factors: the extensively long gas lift supply line that stretches across the western field and the large number of production wells offtaking gas lift to stay online or enhance production. The gas lift supply line is approximately 18.5 miles long and provides gas lift to 200+ production wells. This results in a pressure drop severe enough to start hindering production on the western most side of the field as low gas …

Renewable Energy Development In Alaska: Policy Implications For The Development Of Renewable Energy For Remote Areas Of The Circumpolar Arctic, Gwen Pamela Holdmann

Engineering

The territories that comprise the Arctic region are part of some of wealthiest and most advanced countries on the planet; yet, rural Alaska, northern Canada, the Russian Far East and Greenland--characterized by off-grid communities, regional grids, and higher degrees of energy insecurity--have more in common with the developing world than the southern regions of their own country. This thesis explains this paradox of energy development in the Circumpolar North and tackles the issue of developing renewable energy in remote areas where technical and socioeconomic barriers are significant. The primary research questions are two-fold: 1) Why did the Alaska electrical system …

Perceptions Of Rural Superintendents On Factors Influencing Employment Decisions, Heather P. Williams, Kathleen Shoup, Lisa Colon Durham, Ben A. Johnson, Shannon Dunstan, Brittany A. Brady, Carl F. Siebert

School Leadership Review

School districts struggle to attract and maintain a sufficient supply of highly capable superintendents. High-needs within rural districts, in particular, often are not able to attract and retain effective leaders. The issue of short superintendent tenure has drawn speculation and concern that revolving leadership may have negative consequences for schools and student achievement. A variety of factors contribute to superintendent turnover including: school board relations, job satisfaction, school district characteristics, and the personal characteristics of superintendents (Grissom & Anderson, 2012; Kamrath & Brunner, 2014; Wood, Finch & Mirecki, 2013). This study provides insight into perceptions of rural superintendents (n=10) and …
