Evaluation of City of Denton Sub-Watershed by Benthic Macroinvertebrate Field Experimental Approach

Evaluation of City of Denton Sub-Watershed by Benthic Macroinvertebrate Field Experimental Approach

Access: Use of this item is restricted to the UNT Community.
Date: August 2006
Creator: Mahato, Mahendra
Description: In this study, two different field experiments were designed to assess the relative influence of urbanization on benthic communities. During spring and summer, four urban and one reference sites from Denton County, Texas were selected for benthic macroinvertebrate evaluation. Statistically significant differences in colonized benthic macroinvertebrate taxa on artificial substrates were observed among the four urban sites and the reference site. Oligochaetes and chironomids were the dominant taxa at all sites. Identification of chironomid larvae at the subfamily and genus level to detect differences between sites had higher statistical power than the evaluation based on total chironomids. At the reference site, Caenis, Cladotanytarsus, Orthocladius, and Ceratopogonidae were the dominant taxa, while the urban sites were dominated by Dero, Physella, Ancylidae, Chironomus, Dicrotendipes, Glyptotendipes, Polypedilum, Pseudochironomus, Stenochironomus, and Tanytarsus. These differences may have been dependent upon differences in hydrologic regime and water quality between sites. Significant differences (ANOVA, p < 0.01) in water quality parameters (alkalinity, hardness, nitrates, phosphates, chlorides, sulfates, calcium, magnesium, potassium, and triazine) were found among water samples collected from the reference and urban sites. During the transfer period, most of the Ephemeroptera and Trichoptera taxa and a few other taxa disappeared from artificial substrates that were colonized ...

Germanic Women: Mundium and Property, 400-1000

Germanic Women: Mundium and Property, 400-1000

Date: August 2006
Creator: Dunn, Kimberlee Harper
Description: Abstract Many historians would like to discover a time of relative freedom, security and independence for women of the past. The Germanic era, from 400-1000 AD, was a time of stability, and security due to limitations the law placed upon the mundwald and the legal ability of women to possess property. The system of compensations that the Germans initiated in an effort to stop the blood feuds between Germanic families, served as a deterrent to men that might physically or sexually abuse women. The majority of the sources used in this work were the Germanic Codes generally dated from 498-1024 AD. Ancient Roman and Germanic sources provide background information about the individual tribes. Secondary sources provide a contrast to the ideas of this thesis, and information.

VLSI Architecture and FPGA Prototyping of a Secure Digital Camera for Biometric Application

VLSI Architecture and FPGA Prototyping of a Secure Digital Camera for Biometric Application

Date: August 2006
Creator: Adamo, Oluwayomi Bamidele
Description: This thesis presents a secure digital camera (SDC) that inserts biometric data into images found in forms of identification such as the newly proposed electronic passport. However, putting biometric data in passports makes the data vulnerable for theft, causing privacy related issues. An effective solution to combating unauthorized access such as skimming (obtaining data from the passport's owner who did not willingly submit the data) or eavesdropping (intercepting information as it moves from the chip to the reader) could be judicious use of watermarking and encryption at the source end of the biometric process in hardware like digital camera or scanners etc. To address such issues, a novel approach and its architecture in the framework of a digital camera, conceptualized as an SDC is presented. The SDC inserts biometric data into passport image with the aid of watermarking and encryption processes. The VLSI (very large scale integration) architecture of the functional units of the SDC such as watermarking and encryption unit is presented. The result of the hardware implementation of Rijndael advanced encryption standard (AES) and a discrete cosine transform (DCT) based visible and invisible watermarking algorithm is presented. The prototype chip can carry out simultaneous encryption and watermarking, which ...

Electrochemical Study of Under-Potential Deposition Processes on Transition Metal Surfaces

Electrochemical Study of Under-Potential Deposition Processes on Transition Metal Surfaces

Date: August 2006
Creator: Flores Araujo, Sarah Cecilia
Description: Copper under-potential deposition (UPD) on iridium was studied due to important implications it presents to the semiconductor industry. Copper UPD allows controlled superfilling on sub-micrometer trenches; iridium has characteristics to prevent copper interconnect penetration into the surrounding dielectric. Copper UPD is not favored on iridium oxides but data shows copper over-potential deposition when lower oxidation state Ir oxide is formed. Effect of anions in solution on silver UPD at platinum (Pt) electrodes was studied with the electrochemical quartz crystal microbalance. Silver UPD forms about one monolayer in the three different electrolytes employed. When phosphoric acid is used, silver oxide growth is identified due to presence of low coverage hydrous oxide species at potentials prior to the monolayer oxide region oxide region.

The Undue Burden Standard: The Effects of Planned Parenthood v. Casey (1992) on State Abortion Laws

The Undue Burden Standard: The Effects of Planned Parenthood v. Casey (1992) on State Abortion Laws

Access: Use of this item is restricted to the UNT Community.
Date: August 2006
Creator: Burlage, G. Rachel
Description: This thesis examines the effects of the change from strict scrutiny to the undue burden standard in Planned Parenthood v. Casey (1992). A history of abortion in the United States and the various ways in which government regulates it is explored. Particular attention is focused on the role of the federal judiciary in abortion regulation. Theories of judicial decision making are discussed as means to understand the outcome of cases. Several models are tested to determine which, if any, model explains judicial decision making. The effect of the change in standard, as well as an alternate precedent, are examined.

Resource Management in Wireless Networks

Resource Management in Wireless Networks

Date: August 2006
Creator: Arepally, Anurag
Description: A local call admission control (CAC) algorithm for third generation wireless networks was designed and implemented, which allows for the simulation of network throughput for different spreading factors and various mobility scenarios. A global CAC algorithm is also implemented and used as a benchmark since it is inherently optimized; it yields the best possible performance but has an intensive computational complexity. Optimized local CAC algorithm achieves similar performance as global CAC algorithm at a fraction of the computational cost. Design of a dynamic channel assignment algorithm for IEEE 802.11 wireless systems is also presented. Channels are assigned dynamically depending on the minimal interference generated by the neighboring access points on a reference access point. Analysis of dynamic channel assignment algorithm shows an improvement by a factor of 4 over the default settings of having all access points use the same channel, resulting significantly higher network throughput.

Stressors, Social Support, and Stress Reactions: A Meta-Analysis

Stressors, Social Support, and Stress Reactions: A Meta-Analysis

Date: August 2006
Creator: Piper, Lynn J.
Description: This study examined, via a meta-analysis, the relations among stressors, social support, and stress reactions. Unexpectedly, small to medium negative, but robust effect sizes were found for the stressors-social support relation. As expected the stressor-stress reaction relation was positive, and the social support-stress reaction relation was negative. Both relations had small to medium effect sizes that ranged from weak to very robust. The direct effect of social support on the stressor-stress reaction was generally supported, whereas the suppressor and mediating models were not supported. Furthermore, the findings were inconclusive for the moderator effect of social support. Non-interpersonal traumas appear different in the stressor-social support and social support-stress reaction relations compared to other trauma types. These findings have important clinical implications.
