Scale Invariant Object Recognition Using Cortical Computational Models And A Robotic Platform, Danny Voils

Dissertations and Theses

This paper proposes an end-to-end, scale invariant, visual object recognition system, composed of computational components that mimic the cortex in the brain. The system uses a two stage process. The first stage is a filter that extracts scale invariant features from the visual field. The second stage uses inference based spacio-temporal analysis of these features to identify objects in the visual field. The proposed model combines Numenta's Hierarchical Temporal Memory (HTM), with HMAX developed by MIT's Brain and Cognitive Science Department. While these two biologically inspired paradigms are based on what is known about the visual cortex, HTM and HMAX …

Designing New Drugs To Treat Cardiac Arrhythmia, Yanping Ye

Dissertations and Theses

Heart failure resulting from different forms of cardiomyopathy is defined as the inability of the heart to pump sufficient blood to meet the body's metabolic demands. It is a major disease burden worldwide and the statistics show that 50% of the people who have the heart failure will eventually die from sudden cardiac death (SCD) associated with an arrhythmia. The central cause of disability and SCD is because of ventricular arrhythmias. Genetic mutations and acquired modifications to RyR2, the calcium release channel from sarcoplasmic reticulum, can increase the pathologic SR Ca2+ leak during diastole, which leads to defects in SR …

The sample consisted of 380 SAGE patients who had continuous enrollment in 2005. These patients formed the cohort for the study. Agency records for these …

A Perspective On Resource Synchronization, Herbert Van De Sompel, Robert Sanderson, Martin Klein, Michael L. Nelson, Bernhard Haslhofer, Simeon Warner, Carl Lagoze

Computer Science Faculty Publications

Web applications frequently leverage resources made available by remote web servers. As resources are created, updated, deleted, or moved, these applications face challenges to remain in lockstep with changes on the server. Several approaches exist to help meet this challenge for use cases where "good enough" synchronization is acceptable. But when strict resource coverage or low synchronization latency is required, commonly accepted Web-based solutions remain illusive. This paper provides a perspective on the resource synchronization problem that results from inspiration gained from prior work, and initial insights resulting from the recently launched NISO/OAI ResourceSync effort.

Brown Abroad: An Empirical Analysis Of Foreign Judicial Citation And The Metaphor Of Cosmopolitan Conversation, Sheldon B. Lyke

Vanderbilt Journal of Transnational Law

This Article generates a data set (twelve courts and thirty-two decisions) of foreign judicial citations to the landmark U.S. Supreme Court decision in Brown v. Board of Education. The purpose of this Article is to learn what happens when a case is deterritorialized and reconstituted in a different national scenario, and to conceptualize how courts around the world use foreign authority. My analysis reveals that few foreign courts used Brown in decisions involving education or race and ethnicity. Foreign courts used the case as a form of factual evidence, as a guide in understanding the proper role of a court …

The Influence Of Teacher Preparation Programs' Field Experiences On Pre-Service Teacher Candidates' Sense Of Teaching Efficacy, Alison Marie Reddy

Teaching & Learning Theses & Dissertations

In this descriptive, mixed methods study, the researcher investigated the influence of teacher preparation programs' field experiences on teacher candidates' sense of teaching efficacy. Tschannen-Morgan & Woolfolk-Hoy's (2001) Teacher Sense of Efficacy Scale questionnaire was sent to 221 teacher candidates enrolled in one of five teaching license paths in a large metropolitan university in the eastern part of the United States. Seventy-seven percent of the questionnaires were returned. Questionnaires were analyzed to determine the degree the number of hours of elementary teacher candidates' field experiences influence their perceptions of their teaching efficacy. The questionnaires were also used to compare the …

Enhancing Spectrum Utilization In Dynamic Cognitive Radio Systems, Dusadee Treeumnuk

Electrical & Computer Engineering Theses & Dissertations

Cognitive radio (CR) is regarded as a viable solution to enabling flexible use of the frequency spectrum in future generations of wireless systems by allowing unlicensed secondary users (SU) to access licensed spectrum under the specific condition that no harmful interference be caused to the licensed primary users (PU) of the spectrum. In practical scenarios, the knowledge of PU activity is unknown to CRs and radio environments are mostly imperfect due to various issues such as noise uncertainty and multipath fadings. Therefore, important functionalities of CR systems are to efficiently detect availability of radio spectrum as well as to avoid …

Developing An Open Access Croplands Research Database Through Global Collaboration, Tara Baillargeon, Livia Olsen, Harish Maringanti

Library Faculty Research and Publications

This article describes the processes, challenges, and outcomes of a project undertaken by Kansas State University (K-State) Libraries and a global community of researchers. The project, initiated by librarians in the newly created Faculty and Graduate Services Department, involved collaboration with a K-State agronomist. The initial concept was to create an open access database of croplands research submitted by researchers from the Global Research Alliance Croplands Research Group, a consortium of over 30 countries. Due to the project's complexity, it was determined that a more manageable approach would be to pilot the project by including research from only the United …
