Error Resilient Transmission Of Three-Dimensional Dct Coded Video., Supriya Dilip Sawant Jan 2006

Error Resilient Transmission Of Three-Dimensional Dct Coded Video., Supriya Dilip Sawant

Graduate Theses, Dissertations, and Problem Reports (ETD)

Current multimedia applications involve video transmission over unprotected noisy channels where the video stream is contaminated with errors thereby requiring advanced error concealment/correction strategies. Our objective in this research is to devise error resilient strategies that will help combat channel errors and produce a quality video reconstruction. In this thesis we investigate two error resilient techniques, namely, unequal error protection (UEP) and multiple description coding (MDC) for video transmission. Unlike the traditional video coding system that uses two dimensional transformations accompanied with motion estimation and compensation, we focus on the three dimensional discrete cosine transform (3D DCT). We propose video …

Graduate Theses, Dissertations, and Problem Reports (ETD)

Ergot alkaloids, a category of mycotoxins produced by various fungi, adversely affect both humans and animals. Several plant-associated fungi in the genera Claviceps, Neotyphodium, and Epichloe (order Hypocreales) produce an array of ergot alkaloids. Another fungus, Aspergillus fumigatus that occupies a completely different ecological niche and is classified under the order Eurotiales, also produces ergot alkaloids. The gene clusters predicted to encode the enzymes required for ergot alkaloid production within these species are strikingly similar, however, they are poorly understood. In this study, a gene knockout of the easC gene that encodes a putative catalase resulted in the loss of …

"Mirror Worlds": Transpacific Inspiration And Mimetic Rivalry In American And East Asian Literature, 1945-2005., Matthew J. Packer

Graduate Theses, Dissertations, and Problem Reports (ETD)

One conspicuous trend during the world economy's shift to the Pacific Rim in the late twentieth century has been the increased reciprocal inspiration and mimetic rivalry between American and East Asian cultures. For much of the past century, for example, the Japanese have been stereotyped as cultural copycats, when transpacific imitating actually has been mutual: as East Asians have looked to the West for models of development and the imagination, so have Americans looked to the Far East---as even representing the future, according to novelist William Gibson. Americans have drawn inspiration from Eastern aesthetics, while East Asians have copied Western …

The Expected Value Of Catastrophes In Underground Coal Mines, 1987-2001., Danrick W. Alexander

Graduate Theses, Dissertations, and Problem Reports (ETD)

Eighteen fires, explosions, a flood and an explosives blow-out caused catastrophes during the 15 year period from 1987 to 2001 and led to significant interruptions of production. Three of these events were also disasters that caused 5 or more fatalities. The number of catastrophes per year has held steady while the number of mines has decreased. This has led to a doubling of the number of catastrophes per 1000 mine operating years from 0.77 to 1.65. This growing problem is largely unrecognized. Catastrophes are the largest, most costly single property loss events in the underground coal industry. However, because major …

Graduate Theses, Dissertations, and Problem Reports (ETD)

This dissertation seeks to articulate the extent to which George Eliot engages in an active dialogue with contemporary scientific thought, particularly in respect to England's Jewish and Gypsy populations. I examine The Spanish Gypsy and Daniel Deronda to determine Eliot's position in relation to ideologies on race, gender, and class. Eliot's texts manage to expose some of the contradictions regarding these two "domestic others" within the dominant discourses of the Victorian period. Chapter one sets out my critical and methodological framework and foregrounds the discursive proximity between the Gypsies, the Jews, the working classes, and women in the Victorian period. …

Combinatory Effects Of The Bioflavonoid Apigenin With Chemotherapeutic Drugs On Prostate, Colon, And Lung Cancer Cell Lines, Lesly Anne J. Lopez

Graduate Theses, Dissertations, and Problem Reports (ETD)

Lung, prostate, and colon cancer are among the most commonly diagnosed cancers in Americans. Current chemotherapeutic regimens generally have toxic side effects leading to the death of normal cells. Polyphenols are naturally occurring compounds that can be found in fruits, vegetables and herbs. Apigenin is a polyphenolic compound that has been shown to have antioxidant and anti-inflammatory effects. In this study, apigenin was shown to inhibit the proliferation of several cancer cell lines. The combination of 15 uM apigenin and the chemotherapeutic drugs including doxorubicin, etoposide, mitomycin C, and 5-fluorouracil significantly decreased (P<0.05) the IC50 to inhibit the proliferation of prostate cancer cell lines PC-3 and DU-145 more than the chemotherapeutic drugs alone. Similarly, the addition of apigenin greatly enhanced the sensitivity of colon cancer cell lines HCT-116 and colo-205 and lung cancer lines A549 and H460 to doxorubicin, mitomycin C, 5-fluorouracil, and cisplatin. We analyzed sensitivity via cell death and cell proliferation assays.
