A Quantitative Study of Musical Instrument Digital Interface (MIDI) Over Internet Protocol (IP) Protocols
(2005-12-15)
The research, which is discussed in this dissertation, consists of the development and testing of a suite of ten Transmission Control Protocol (TCP) and reliable Real Time Protocol (RTP) MIDI over IP (MOIP) protocols, and ...
The Activity Metric for Low Resource, On-line Character Recognition
(2005-12-15)
This work presents an algorithm for on-line character recognition that is fast, portable, and consumes very little memory for code or data. The algorithm is alphabet-independent, and does not require training beyond ...
Reconstructing the Past Salinities Experienced by a Freshwater and Marine Piscivore in the Mobile-tensaw River Delta Using Otolith Microchemistry
(2007-12-15)
In this study, we used changes in otolith microchemistry, with particular emphasis on otolith Sr:Ca, along the otolith growth axis to examine the past salinities, and thus the past environments, experienced by age-0 ...
Distribution, abundance, and population characteristics of shoal bass in tributaries of the Chattahoochee River, Alabama
(2007-12-15)
The shoal bass Micropterus cataractae is the most recently described black bass species and in east-central Alabama, this fish only occurs in streams that flow into the Chattahoochee River. Recently, shoal bass were listed ...
Replacement of Poultry By-Product Meal in Production Diets for the Pacific White Shrimp (Litopenaeus vannamei)
(2007-12-15)
In recent years there has been increasing interest in the replacement of animal proteins with plant proteins in commercial feeds for the Pacific white shrimp, Litopenaeus vannamei. Primary reasons for this interest are to ...
Physical-Chemical and Biological Characterization of Small Streams Following Intensive Forest Management Practices in the Coastal Plain of Alabama
(2007-12-15)
This study measured changes in five first-order streams (S 1 through S 5) following management techniques including clearcut logging and chemical (S 2 and S 3) and mechanical site preparation (S 4 and S 5). The herbicides ...
An Evaluation of Natural and Artificial Dietary Lipid Sources on Egg Quality and Fry Production in Channel Catfish (male) X Blue Catfish (female) Hybridization
(2007-12-15)
Hybrid catfish (channel catfish Ictalurus punctatus? x blue catfish I. furcatus?) display many characteristics that are favorable to aquaculture production such as increased growth, resistance to disease, higher dress out ...
Technical and Educational Aspects of Stream Biomonitoring Protocols for Teachers and Citizen Monitors in Alabama
(2007-12-15)
Accuracy of the Alabama Water Watch (AWW) Stream Biomonitoring Protocol for citizen monitors was assessed through a desktop study comparing simulated AWW stream quality assessments to known professional bioassessments. ...
Effects of Spatial and Temporal Variability of Shoal Habitat on Stream Fish Assemblages in Chattahoochee Tributaries, Alabama
(2007-12-15)
Abiotic factors associated with habitat quality may have profound effects on fish assemblage structure. Variability in physical habitat parameters as well as temporal fluctuation in characteristics such as water depth and ...
The Economic Significance of Aquatic Biotechnology in the Production of Channel Catfish (Ictalurus punctatus) Female X Blue Catfish (I. furcatus) Male Hybrid (CB Hybrid) Embryos
(2007-12-15)
The current cost of commercially producing CB hybrid catfish fry is 325% higher than that of channel catfish due to the CB hybrid’s high production costs and low hatch rates. However, CB hybrid catfish fingerlings cost ...
Evaluation of Three Fish Species for Culture Using Low Salinity Groundwater in the Black Belt Region of Alabama
