Band To Band Calibration And Relative Gain Analysis Of Satellite Sensors Using Deep Convective Clouds, Suman Bhatta
Band To Band Calibration And Relative Gain Analysis Of Satellite Sensors Using Deep Convective Clouds, Suman Bhatta
Electronic Theses and Dissertations
Two calibration techniques were developed in this research. First, a calibration technique, in which calibration was transferred to cirrus band and coastal aerosol band from well calibrated reflective bands of Landsat 8 using SCIAMACHY Deep Convective Cloud (DCC) spectra. Second, a novel method to derive relative gains using DCCs and improve the image quality of cirrus band scenes was developed. DCCs are very cold, bright clouds located in the tropopause layer. At small sun elevation and sensor viewing angles, they act as near Lambertian solar reflectors. They have very high signal to noise ratio and can easily be detected using …
Modeling The Impact Of Future Climate On Drainage Infrastructures, Tyler J. Baumbach
Modeling The Impact Of Future Climate On Drainage Infrastructures, Tyler J. Baumbach
Electronic Theses and Dissertations
Research has shown a potential 20% increase in future heavy and extreme precipitation events over the Midwestern States. Drainage infrastructures designed using current design conditions may not be able to convey projected runoffs resulting in flooding and damage to infrastructure. The objective of this paper is to determine the effects of future climate variability on culvert selections in a southwest South Dakota watershed. The scope of the study was defined through a comprehensive literature review. Future climate events were based on a 20% increase in current annual precipitation over the Upper White River Subbasin Watershed. A portion of the White …
Studies Related To Microbially Induced Corrosion Of Stainless Steel 304 And 316, Somil Gupta
Studies Related To Microbially Induced Corrosion Of Stainless Steel 304 And 316, Somil Gupta
Electronic Theses and Dissertations
Pitting corrosion of stainless steel (SS) is observed in many different industries including the dairy industry. It is of concern, because it weakens the steel, and can cause cracking. Any replacement or repair of SS equipment is very costly and also causes delays in product manufacture. Microbial Induced Corrosion (MIC) is a possible accelerator of natural corrosion seen in galvanized steel pipes. Studies have shown a correlation between surface roughness and the ability of bacteria to colonize and form biofilms. Dairy industry utilizes higher food grade SS 304 and 316. However, even these relatively corrosion resistant stainless steel grades may …
Effect Of Ph And Temperature On Halogenated Dbps, Sm Shamimur Rahman
Effect Of Ph And Temperature On Halogenated Dbps, Sm Shamimur Rahman
Electronic Theses and Dissertations
Water scarcity is one of the most challenging issues in the world in the 21st century. It is estimated that there are more than one billion of people without adequate access to freshwater and facing water shortages and water deficits. People are forced to drink polluted water despite the risk of consuming pathogenic microorganisms in the water that transmit waterborne diseases such as bacterial infections, protozoal infections and viral infections. The water disinfection process is one of the most important environmental technological advances in the 20th century which inactivates microbial contaminants in drinking water. Disinfection byproducts (DBPs) are a group …
A Process-Based Nutrient Model For The Bedded Manure Pack Of Confined Beef Systems, Ferouz Y. Ayadi
A Process-Based Nutrient Model For The Bedded Manure Pack Of Confined Beef Systems, Ferouz Y. Ayadi
Electronic Theses and Dissertations
Manure management is of growing concern for beef cattle producers and the general public. The overall objective of this research was to develop a process-based model that predicts concentration and gaseous emission from the bedded manure pack of a confined beef cattle system, with respect to different bedding material, manure storage time, and ambient temperature. The model incorporated the data collected in three experiments designed to understand transformations and processes occurring in the bedded pack. The first study evaluated the source of volatilized ammonia nitrogen from beef cattle manure. Isotope ratio mass spectrometry was used to determine the origin of …
