A New Wireless Sensor Node Design for Program Isolation and Power Flexibility

A New Wireless Sensor Node Design for Program Isolation and Power Flexibility

Date: December 2009
Creator: Skelton, Adam W.
Description: Over-the-air programming systems for wireless sensor networks have drawbacks that stem from fundamental limitations in the hardware used in current sensor nodes. Also, advances in technology make it feasible to use capacitors as the sole energy storage mechanism for sensor nodes using energy harvesting, but most current designs require additional electronics. These two considerations led to the design of a new sensor node. A microcontroller was chosen that meets the Popek and Goldberg virtualization requirements. The hardware design for this new sensor node is presented, as well as a preliminary operating system. The prototypes are tested, and demonstrated to be sustainable with a capacitor and solar panel. The issue of capacitor leakage is considered and measured.

News photography image retrieval practices: Locus of control in two contexts.

News photography image retrieval practices: Locus of control in two contexts.

Access: Use of this item is restricted to the UNT Community.
Date: May 2006
Creator: Neal, Diane Rasmussen
Description: This is the first known study to explore the image retrieval preferences of news photographers and news photo editors in work contexts. Survey participants (n=102) provided opinions regarding 11 photograph searching methods. The quantitative survey data were analyzed using descriptive statistics, while content analysis was used to evaluate the qualitative survey data. In addition, news photographers and news photo editors (n=11) participated in interviews. Data from the interviews were analyzed with phenomenography. The survey data demonstrated that most participants prefer searching by events taking place in the photograph, objects that exist in the photograph, photographer-provided keywords, and relevant metadata, such as the date the picture was taken. They also prefer browsing. Respondents had mixed opinions about searching by emotions elicited in a photograph, as well as the environmental conditions represented in a photograph. Participants' lowest-rated methods included color and light, lines and shapes, and depth, shadow, or perspective. They also expressed little interest in technical information about a photograph, such as shutter speed and aperture. Interview participants' opinions about the search methods reflected the survey respondents' views. They discussed other aspects of news photography as well, including the stories told by the pictures, technical concerns about digital photography, and digital ...

Newspaper Ownership Structure and the Quality of Local Political News Coverage

Newspaper Ownership Structure and the Quality of Local Political News Coverage

Date: May 2012
Creator: Clark, Karla Christine Marie
Description: This research sought to ascertain how newspaper ownership structures influence the quality of local political news coverage. More specifically, do independently owned newspapers tend to produce larger quantities of quality local political reporting than do corporately owned and publicly traded newspapers? In the thesis, I develop an understanding of "quality" news coverage as being coverage that is thematic, or providing interpretive analysis and supplying contextual information. Additionally, I tackle the question of quality news coverage from three angles: whether or not independently owned newspapers provide more quality local political news stories per edition than corporately owned papers; whether or not the percentage of quality local political news stories of total political news stories within an edition is higher for independently owned or corporately owned newspapers; and whether or not the percentage of total political news stories of total news stories is higher for independently owned or corporately owned newspapers.

Nicotinic Acetylcholine Receptor α3 mRNA in Rat Visual System After Monocular Deprivation

Nicotinic Acetylcholine Receptor α3 mRNA in Rat Visual System After Monocular Deprivation

Date: August 1997
Creator: Taylor, James H. (James Harvey), 1970-
Description: In situ hybridization was used to examine effects of monocular enucleation on nicotinic acetylcholine receptor subunit cc3 mRNA in the rat dLGNand visual cortex. After 28 days postoperative, there were no significant differences in α3 mRNA density between the contralateral (deprived) and ipsilateral (non-deprived) sides. The lack of obvious effects of visual deprivation on α3 mRNA density suggests that other factors, possibly intrinsic to dLGNand visual cortex, govern the postnatal expression of α3 mRNA.

The “Nigger Trinity”: Engaging the Discourse in Post Civil Rights/Post 1960s America

The “Nigger Trinity”: Engaging the Discourse in Post Civil Rights/Post 1960s America

Access: Use of this item is restricted to the UNT Community.
Date: December 2011
Creator: Bell, Adrian Shane
Description: The cultural and popular media landscape of the United States of America changed after the Civil-Rights movement of the 1960s. The word “Nigger” was changed during that same period of American history. There are several authors and a comic that helped change this word during the 1960s. The post Civil-Rights American has a different experience and understanding with this word than those born before 1970. This work triangulates the current cultural location of the word “Nigger,” “nigga,” and “the n-word” using linguistics, law, and two media case studies. The “Nigger” trinity is a model that adds value to the discourse that surrounds this one word in post civil-rights/post 1960s America.

Night of no Exile

Night of no Exile

Date: August 1999
Creator: Jones, Marie C.
Description: Night of no Exile is a collection of poems preceded by a critical article entitled "‘Exile seems both a blessing and a curse': A Blissful Reading of Li-Young Lee's Poetry." That article discusses Lee's quest to achieve communication, truth, and transcendence through poetic language and concludes that he finally reaches his goal through a leap from narrative poetry to lyricism. The "exile" alluded to in the title of the article is not only geographic, but also interioran exile due to the natural limitations of all languages, and which can be bridged only in linguistic ways. Lee's solution to that problem (lyricism) turns his poetry into what Roland Barthes would call "a text of bliss," a text that manages to deeply destabilize language, while simultaneously achieving a new kind of meaning. In the main body of the manuscript, the first section contains short love lyrics. The second section, "Night of no Exile," is an attempt at the demanding genre of the longer lyric poem. The third section uses short lyrics to explore various topics, such as discovering one's identity, friendship and solidarity between women, family history, and childhood memories. Finally, the last section includes poems, four of them longer, attempting to ...

Access: Use of this item is restricted to the UNT Community.
Date: May 2003
Creator: Blizzard, Amy
Description: This thesis surveys a variety of songs and arias for high soprano which feature the nightingale; examines the musical elements that symbolize, refer to, or imitate the nightingale; and compares these musical elements with transcriptions of the nightingale's song. The first chapter reviews the symbolic development of the nightingale and its role in poetry and literature. The interior chapters address a selection of musical compositions that feature the nightingale and its song. The final chapter establishes a relationship between the sound of the actual sound of the nightingale and the musical gestures created by composers to imitate the nightingale.

Date: December 2000
Creator: Couturiaux, Clay
Description: An analysis of the transformation from Stravinsky's opera The Nightingale to The Song of the Nightingale, a symphonic poem by the same composer. The text includes a brief history of Stravinsky's life and the genesis of The Nightingale and The Song of the Nightingale. The bulk of the dissertation discusses actual changes employed by Stravinsky (with score examples). Patterns of modifications are identified and discussed as they relate to the composer's change of attitude in orchestration. The analysis focuses on overall patterns of alteration imposed by Stravinsky and their perceived effectiveness achieving a symphonic aural outcome.

Nihilism and the Formulation of a Philosophy of Art

Nihilism and the Formulation of a Philosophy of Art

Date: May 2011
Creator: Hernandez, Brian
Description: Nihilism is often associated with feelings of despair, hopelessness and meaningless. It is certainly true that once the implications of this philosophy become apparent that these feelings are valid. However, this reaction is merely the first stage of dealing with nihilism and stopping here fails to examine the various types of nihilism that deal specifically with knowledge, ethics, metaphysics, truth, and art. Nihilism at its base is a philosophy that recognizes the history of human thought and what it means to be and to think. My focus is the way in which a completed nihilism is in fact an emancipatory act and the implications it has for art and the artist in the 21st century.
