Unidirectional error correcting/detecting codes

Creator:: Lin, Der Jei
Abstract:: An extensive theory of symmetric error control coding has been developed in the last few decades. The recently developed VLSI circuits, ROM, and RAM memories have given an impetus to the extension of error control coding to include asymmetric and unidirectional types of error control. The maximal numbers of unidirectional...

Development of a test procedure for water sensitivity of asphalt concrete mixtures

Creator:: Al-Swailmi, Saleh H.
Abstract:: Environmental factors such as temperature, air, and water can have a profound effect on the durability of asphalt concrete mixtures. In mild climates where good quality aggregates and asphalt cement are available, the major contribution to deterioration may be due to traffic loading and the resultant distress is manifested in...

New bioactive natural products from marine algae and cyanobacteria

Creator:: Sabry, Omar Mohamed
Abstract:: This thesis is an account of investigation on the natural products deriving from various marine algae and has resulted in the discovery of eleven novel bioactive metabolites. Isolation and characterization of these new molecules were carried out using different chromatographic techniques and by analyses of different spectroscopic data, respectively. Using...

Balanced codes

Creator:: Al-Bassam, Sulaiman
Abstract:: Balanced codes, in which each codeword contains equally many 1's and 0's, are useful in such applications as in optical transmission and optical recording. When balanced codes are used, the same number of 1's and 0's pass through the channel after the transmission of every word, so the channel is...

Alternatives to the DNA precursor-synthesizing enzyme complex hypothesis

Creator:: Weitz, Stephen L.
Abstract:: Investigators have been studying an aggregate containing enzymes of deoxyribonucleoside triphosphate biosynthesis in T4-phage infected bacteria. They suggest that it behaves as an organized complex, efficiently channeling DNA precursors to the replication apparatus. Previous work has suggested that about 10 enzyme activities remain associated through several fractionation steps. This multi-enzyme...

Pattern recognition of speech using hybrid computer feature extraction

Creator:: Herr, Alan Jack
Abstract:: Most technological problems associated with man-machine conversations have been solved and are well documented in both the contemporary technical and lay literature. The major remaining technological problem is the real time conversion of a human's vocal uterances into a "written" phoneme sequence representing the information content of speech. The work...

Understanding large resurgent calderas and associated magma systems : the Pastos Grandes Caldera Complex, southwest Bolivia

Creator:: Kaiser, Jason Frederick, 1985-
Abstract:: The Pastos Grandes Caldera Complex (PGCC) in southwest Bolivia has produced two large-volume (≥800 km³ DRE) dacite ignimbrites from a nested caldera source over a period of 5.5 Myr. In addition to the large-volume ignimbrites, a small-volume ignimbrite shield and post-climactic lavas define this composite system. Based on detailed field...

Seasonal thermoregulation in the dark-eyed junco (Passeriformes: Junco hyemalis)

Creator:: Swanson, David Leslie
Abstract:: Winters in north-temperate climates impose high thermogenic demands upon small birds which are met by seasonal acclimatization. This thesis investigates the extent and mechanisms of seasonal acclimatization in darkeyed juncos (Junco hyemalis) inhabiting western Oregon. Although insulation is significantly increased in winter, acclimatization is primarily metabolic. Increased metabolism is required...

Perinatal and postweaning effects of the interaction between maternal ethanol ingestion and low dietary zinc in the rat

Creator:: Yeh, Lee-chuan C.
Abstract:: This research was designed to study the perinatal and postweaning effects of the interaction between ethanol and low dietary zinc during gestation and lactation in the rat. Pregnant rats were fed liquid diets containing either 2 or 10 μg zinc/ml with or without 30% of kcal from ethanol throughout gestation...
