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 ...

Female Inheritors of Hawthorne's New England Literary Tradition

Female Inheritors of Hawthorne's New England Literary Tradition

Date: August 1994
Creator: Adams, Dana W. (Dana Wills)
Description: Nineteenth-century women were a mainstay in the New England literary tradition, both as readers and authors. Indeed, women were a large part of a growing reading public, a public that distanced itself from Puritanism and developed an appetite for novels and magazine short stories. It was a culture that survived in spite of patriarchal domination of the female in social and literary status. This dissertation is a study of selected works from Nathaniel Hawthorne, Sarah Orne Jewett, and Mary E. Wilkins Freeman that show their fiction as a protest against a patriarchal society. The premise of this study is based on analyzing these works from a protest (not necessarily a feminist) view, which leads to these conclusions: rejection of the male suitor and of marriage was a protest against patriarchal institutions that purposely restricted females from realizing their potential. Furthermore, it is often the case that industrialism and abuses of male authority in selected works by Jewett and Freeman are symbols of male-driven forces that oppose the autonomy of the female. Thus my argument is that protest fiction of the nineteenth century quietly promulgates an agenda of independence for the female. It is an agenda that encourages the woman to ...

Base Effects on the Thermal Decomposition of Sec-butyllithium Solutions

Base Effects on the Thermal Decomposition of Sec-butyllithium Solutions

Date: June 1966
Creator: Adams, George Michael
Description: The pyrolysis of sec-butyllithium in solution was studied in an attempt to understand the loss of stereo-specificity and the atypical kinetics that have been reported. Additionally, the effect of added lithium alkoxides was studied to determine their effects on the highly reactive sec-butyllithium substrate.

A Study of the Bacterial Flora of Food Utensils in Hardin College Cafeteria and Twenty-Five Eating Establishments in Wichita Falls, Texas

A Study of the Bacterial Flora of Food Utensils in Hardin College Cafeteria and Twenty-Five Eating Establishments in Wichita Falls, Texas

Date: 1949
Creator: Adams, Isaac Newton
Description: The problem of this thesis consists primarily of a bacteriological survey of the eating utensils of Hardin College Cafeteria and twenty-five other eating establishments in the city of Wichita Falls, Texas. This investigation was made primarily with reference to a determination of the possible presence of typhoid and related organisms, and secondarily to an investigation of the actual presence of those bacterial organisms associated with the more common outbreaks of food poisoning.

The Relationship Between Supplemental Instruction Leader Learning Style and Study Session Design

The Relationship Between Supplemental Instruction Leader Learning Style and Study Session Design

Date: May 2011
Creator: Adams, Joshua
Description: The purpose of this qualitative study was to examine the learning styles of supplemental instruction leaders at a large, public university during the fall 2010 semester and determine whether or not their personal learning styles influenced the way they designed and developed out-of-class study sessions. The total population of supplemental instruction leaders was 37, of which 24 were eligible to participate in the study. Of the 24 eligible supplemental instruction leaders, 20 completed the entire study. Participants in the study included nine male and 11 female supplemental instruction leaders with a median age of 22.25 years-old. Seventeen participants indicated their classification as senior, two as junior, and one as sophomore. Of the participants, 16 indicated white as a race or ethnicity, one indicated Asian, two indicated African American, and one indicated both American Indian/Alaska Native and white. Supplemental instruction leader learning style was assessed using the Kolb Learning Style Inventory. Leaders were then interviewed, and their study sessions were analyzed. Through triangulation of data from learning style, interviews and actual study session documents, four major themes emerged. The four themes were: 1) incorporation of personal experience into study session design, 2) the sense of impact on student learning, 3) a ...
