Digital PhotographyWhipple, Julie F. 07 August 2008 (has links)
My professional paper is designed as a teaching tool to help other instructors to be able to teach the basics of digital photography to their students. It includes a brief history of the development of photography, information about the digital camera, how to take better pictures, and how to begin working with photos using Photoshop. Instructions and lesson plans are designed to teach all levels of students learning abilities.

Associations between hydrological connectivity and resource partitioning among sympatric gar species (Lepisosteidae) in a Texas river and associated oxbowsRobertson, Clinton Ray 15 May 2009 (has links)
The middle Brazos River, located in east central Texas, is a meandering lowland
river that contains many oxbow lakes on its floodplain. Flood dynamics of the Brazos
River are aseasonal, and faunal exchange during lateral connections of the main river
channel and oxbows is pulse-like and only occurs during floods that may be months or
years apart. Patterns of resource use among sympatric gar species (Lepisosteus oculatus,
L. osseus, and Atractosteus spatula) associated with river-floodplain connectivity was
studied for a period of two years (May 2003 to May 2005). The first year was relatively
dry yielding few lateral connections, whereas the second year was relatively wet
resulting in more frequent lateral connections. This study focused on habitat and diet
partitioning among the three gar species in oxbow habitats with different connection
frequencies and an active river channel site. Overall, 684 gars were collected with
experimental gillnets: 19 A. spatula (alligator gar), 374 L. oculatus (spotted gar), and 291 L. osseus (longnose gar). There was strong partitioning of habitat between spotted
and longnose gars, in which 98% of spotted gars were captured in oxbow habitats and
84% of longnose gars were captured in the river channel. Hydrology did not appear to
affect habitat partitioning, although longnose gar abundance significantly increased in
oxbows during the wet year. Diet overlap was high between spotted and longnose gars.
Temporal variation in diet was significantly influenced by flood pulses that connected
oxbows with the river channel, and which allowed predators and their prey to move
between habitats.

Optical Pulse Generation using Electrobsorption MoudulationCai, Wen-hao 09 August 2006 (has links)
Electroabsorption modulator (EAM) has been known with high transmission efficiency, saturation absorber, the high nonlinearity and high speed. In this work, we use a high-speed EAM in a fiber ring structure to generate short pulse train by active mode-locking method. Inside the cavity, Erbium Doped Fiber Amplifier (EDFA) is adopted as the gain medium due to its wide operation wavelength range (about 1530nm to 1570nm) and high gain saturation power.
The mode-locked optical pulse train driven by a 4 GHz microwave source has been successfully designed and measured with filter-limited 21.2 ps pulse width (FWHM) and output power of 10 mw. Clean and stable level of signal with fundamental frequency of 4GHz is obtained through the measurement by optical spectrum analyzer, electronic spectrum analyzer and sampling scope. By tuning the optical path, the highest optical transmission with the shortest pulse and the largest photocurrent is found in EAM, indicating the dominated mechanism is the saturation of optical absorption.
