Selling Civil Defense: The Politics And Commerce Of Preparedness, 1950--1963, Angela Christine Moor Jan 2008

Selling Civil Defense: The Politics And Commerce Of Preparedness, 1950--1963, Angela Christine Moor

UNLV Retrospective Theses & Dissertations

This thesis, by examining how business, government, and civic leaders promoted civil defense, shows how a policy of self-help merged the roles of citizen and consumer and how family-centered preparedness equated the survival of the nuclear family with the victory of the US in the Cold War. Civil defense officials helped reinforce messages about gender roles by stressing the value of nuclear families and the crucial role each family member played in the defense of America. Public information campaigns emphasized the importance of free enterprise and privatization by endorsing a policy of self-help for American families whereby individual families were …

Working Memory Deficits In Psychotic Bipolar Disorder: Trait Marker For Psychosis, Carol Randall Jan 2008

Working Memory Deficits In Psychotic Bipolar Disorder: Trait Marker For Psychosis, Carol Randall

UNLV Retrospective Theses & Dissertations

There is significant overlap in the symptom presentation and cognitive impairment found in individuals with bipolar disorder with psychotic features and in those with some subtypes of schizophrenia. Due to this overlap, debate regarding the existence and nature of a relationship between these disorders has been an ongoing and complicated one. Some continue to view these disorders as they are conceptualized in the current psychiatric diagnostic manual, as distinct and categorical in nature. Others have proposed an "affective-psychotic spectrum" with schizophrenia lying at one end of this spectrum, non-psychotic affective disorders lying at the opposite end of the spectrum, and …

Implementation Of Bma Based Motion Estimation Hardware Accelerator In Hdl, Nachiket Jugade Jan 2008

Implementation Of Bma Based Motion Estimation Hardware Accelerator In Hdl, Nachiket Jugade

UNLV Retrospective Theses & Dissertations

Motion Estimation in MPEG (Motion Pictures Experts Group) video is a temporal prediction technique. The basic principle of motion estimation is that in most cases, consecutive video frames will be similar except for changes induced by objects moving within the frames. Motion Estimation performs a comprehensive 2-dimensional spatial search for each luminance macroblock (16x16 pixel block). MPEG does not define how this search should be performed. This is a detail that the system designer can choose to implement in one of many possible ways. It is well known that a full, exhaustive search over a wide 2-dimensional area yields the …

Impact Of Variable Transmission Range In All-Wireless Networks, Prathima Sajja Jan 2008

Impact Of Variable Transmission Range In All-Wireless Networks, Prathima Sajja

UNLV Retrospective Theses & Dissertations

In this thesis, we propose three distributed algorithms for self-adjusting the transmission range of nodes in wireless network. The objective is to vary the transmission radii of selective sensor nodes to lower the energy spent in broadcasting or the diameter. The sensor nodes start arbitrarily with different transmission ranges. The nodes positions are fixed, and can adjust the transmission power. However, increasing the transmission power to reach more nodes may consume more energy. So, the goal is to reduce the transmission power (i.e., save energy) without reducing the reachability (in terms of the number of nodes); We propose two algorithms …
