An Implementation of Consensus Through Bluetooth Communication

An Implementation of Consensus Through Bluetooth Communication

Date: May 2014
Creator: Wang, Yinan
Description: This thesis provides an implementation of consensus of multi-agent networked systems. Consensus problem is an important issue of distributed computing and has various algorithms and applications in the field of electronical and computer science. The consensus requests all nodes of a network reach an agreement over a certain measurement. An algorithm of convergent consensus problem is implemented through a small network of Bluetooth communication in the thesis. The connections of the Bluetooth devices are wireless, and the device nodes of the network are driven by C++ software and Winsock API. The simulation results show that the implementation completes all the requirements of the distributed consensus algorithm.

Importance and Spatial Distribution of Phytophthora Ramorum Host Species in a Coast Redwood Forest

Importance and Spatial Distribution of Phytophthora Ramorum Host Species in a Coast Redwood Forest

Date: May 2014
Creator: Gray, Alicia E.
Description: Phytophthora ramorum, an exotic forest pathogen known as ‘sudden oak death’ (SOD), has received considerable attention in recent years because of its effects on vegetation structure, composition, and fire disturbance regimes in western U.S. coastal forests. This research examines differences in the importance (e.g., density, dominance, and frequency) and distribution of five host species of P. ramorum–– Umbellularia californica (California bay laurel), Quercus agrifolia (coast live oak), Pseudotsuga menziesii (Douglas fir), Sequoia sempervirens (Coast redwood), and Arbutus menziesii (Madrone)––in Soquel, California. A stratified random sampling design was used to select 66 plots surrounding a managed forest edge in Soquel Demonstration State Forest. Vegetation measurements were conducted in summer 2013. In each plot, all trees ≥3 cm diameter at breast height (DBH) were identified to species, counted, and DBH, height, and canopy position measured. Leaf area index (LAI) of bay laurel was measured to quantify the amount of leaves available for pathogen dispersal with a LiCOR 2200 Plant Canopy Analyzer. In addition, morning (9:00 am) and afternoon (1:00 pm) photosynthetically active radiation (PAR) were quantified using a quantum light sensor. This paper examines the influence of environmental variables, including distance to edge, aspect, slope, and light availability on host species spatial ...

“The Inevitable: Withdrawn”

“The Inevitable: Withdrawn”

Access: Use of this item is restricted to the UNT Community.
Date: May 2014
Creator: Christy, Gwendolyn Anne
Description: The Inevitable: Withdrawn is a critical preface and collection of non-fiction writing: personal essay, lyric essay, fragments, and experimental forms. The work’s cohesive subject matter is the author’s European vacation directly following her divorce. Within the pieces, the author attempts to reconcile who she is when starting over and she begins to ask questions regarding the human condition: How do I learn to exhibit intimacy again, not just with romantic partners, but with also in a familial way with my father, and how does absence in these relationships affect my journey and how I write about it? How do I view, and remake myself, when finding my identity that was tied to another individual compromised? How does a body, both physical and belonging to me, and physical as text, take certain shapes to reflect my understanding? How do I define truth, and how do I interpret truth and authenticity in both experience and writing? How do I define and know the difference between belief and truth? And finally, how does narrative and language protect, or expose me? The Inevitable: Withdrawn considers debates regarding the definition of narrative in order to address a spectrum of non-fiction writing. The collection takes into ...

The Intimacy of Death: Mahler’s Dramatic Narration in Kindertotenlieder

The Intimacy of Death: Mahler’s Dramatic Narration in Kindertotenlieder

Date: May 2014
Creator: Strange, AnnaGrace
Description: There has been relatively little scholarship to date on Mahler’s Kindertotenlieder. The writings about this song cycle that do exist primarily focus on the disparate nature of the poems and justify Kindertotenlieder as a cycle by highlighting various musical connections between the songs, such as keys and motivic continuity. Mahler, however, has unified the cycle in a much more complex and sophisticated way. His familiarity with Wagner’s music and methods, and his mastery of the human voice and orchestral voices allowed him to weave a dramatic grief-laden narrative.

Is Mindfulness Just Another Ego Depletion Exercise?

Is Mindfulness Just Another Ego Depletion Exercise?

Date: May 2014
Creator: Connally, Melissa Londoño
Description: Given increasing interest in the therapeutic benefits of mindfulness, limitations of its treatment utility are frequently questioned. As such, the purpose of the study was to examine the effects of mindfulness on a subsequent self-control task in a sample of college students. A total of 67 participants were randomly assigned to one of three conditions: a control condition, an experimental mindfulness-only condition or a comparison expectancy-plus-mindfulness condition to investigate the utility of mindfulness practice when motivated by an outcome of increased self-control. Results did not indicate a difference in persistence on a difficult task between conditions, regardless of the manipulation. Conceptual and experimental limitations of current study’s findings, as well as future directions, are discussed.

En La Frontera Entre La Vida Y La Muerte: a Study of Women Reporters on the Us–mexico Border

En La Frontera Entre La Vida Y La Muerte: a Study of Women Reporters on the Us–mexico Border

Date: May 2014
Creator: Guzman, Samantha
Description: In 2008 Ciudad Juarez erupted in a violent drug war. The Sinaloa Cartel and Juarez Cartel were in a battle for the lucrative drug route used to smuggle drugs into the United States, while President Felipe Calderon was waging his own war against all the drug cartels. During the height of the violence women journalists emerged on the front lines to tell the stories of Juarez. They risked their lives and dared to tell a story that others refused to. This mixed-method study examines frames used most often in the coverage of the drug war in Ciudad Juarez from 2008-2010. It examines The New York Times, the El Paso Times, and El Norte and also examines articles by the sex of the reporter. It also used in-depth interviews of both Mexican and American woman journalists who covered the drug war in Juarez to examine which themes developed about the reporter’s experiences in covering the drug war.

A Lego Mindstorms Nxt Based Test Bench for Multiagent Exploratory Systems and Distributed Network Partitioning

A Lego Mindstorms Nxt Based Test Bench for Multiagent Exploratory Systems and Distributed Network Partitioning

Date: May 2014
Creator: Patil, Riya Raghuvir
Description: Networks of communicating agents require distributed algorithms for a variety of tasks in the field of network analysis and control. For applications such as swarms of autonomous vehicles, ad hoc and wireless sensor networks, and such military and civilian applications as exploring and patrolling a robust autonomous system that uses a distributed algorithm for self-partitioning can be significantly helpful. A single team of autonomous vehicles in a field may need to self-dissemble into multiple teams, conducive to completing multiple control tasks. Moreover, because communicating agents are subject to changes, namely, addition or failure of an agent or link, a distributed or decentralized algorithm is favorable over having a central agent. A framework to help with the study of self-partitioning of such multi agent systems that have most basic mobility model not only saves our time in conception but also gives us a cost effective prototype without negotiating the physical realization of the proposed idea. In this thesis I present my work on the implementation of a flexible and distributed stochastic partitioning algorithm on the Lego® Mindstorms’ NXT on a graphical programming platform using National Instruments’ LabVIEW™ forming a team of communicating agents via NXT-Bee radio module. We single out mobility, ...
