Error Flow In Computer Programs, Branson Wayne Murrill Jan 1991

Error Flow In Computer Programs, Branson Wayne Murrill

Dissertations, Theses, and Masters Projects

White box program analysis has been applied to program testing for some time, but this analysis is primarily grounded in program syntax, while errors arise from incorrect program semantics. We introduce a semantically-based technique called error flow analysis, which is used to investigate the behavior of a program at the level of data state transitions. Error flow analysis is based on a model of program execution as a composition of functions that each map a prior data state into a subsequent data state. According to the fault/failure model, failure occurs when a fault causes an infection in the data state …


Stock Enhancement Of Caribbean Spiny Lobster, Panulirus Argus Latrielle, Using Artificial Shelters: Patterns Of Survival And Dynamics Of Shelter Selection, David Bryan Eggleston Jan 1991

Stock Enhancement Of Caribbean Spiny Lobster, Panulirus Argus Latrielle, Using Artificial Shelters: Patterns Of Survival And Dynamics Of Shelter Selection, David Bryan Eggleston

Dissertations, Theses, and Masters Projects

Field tethering experiments in seagrass beds of Bahia de la Ascension, Mexico examined the impact of different-sized artificial shelters upon survival of three juvenile size-classes of the Caribbean spiny lobster, Panulirus argus. The artificial shelters were concrete structures (casitas) that simulate lobster dens. In the tethering experiments, spiny lobster survival was generally higher in smaller than larger casitas, though the effect depended upon the relationship between lobster and shelter size. Thus, spiny lobster survival depends not only upon the availability of shelter, but also on the scaling between shelter size and lobster size. These results suggest that placement of appropriately-scaled …

Ecology Of Estuarine Fish Assemblages In Patos Lagoon, Brazil (32 Degrees S), And York River, Usa (37 Degrees N), With Review Of Zoogeography Of Fishes In Western Atlantic Warm-Temperate And Tropical Estuaries, Joao P. Vieira Jan 1991

Ecology Of Estuarine Fish Assemblages In Patos Lagoon, Brazil (32 Degrees S), And York River, Usa (37 Degrees N), With Review Of Zoogeography Of Fishes In Western Atlantic Warm-Temperate And Tropical Estuaries, Joao P. Vieira

Dissertations, Theses, and Masters Projects

The first two chapters of this study examine faunal composition and latitudinal patterns in diversity of fishes in warm-temperate and tropical estuarine waters of the western Atlantic from La Plata River (35&\sp\circ&S), Argentina, to Chesapeake Bay (37&\sp\circ&N), USA (33 faunal reports). Species distributions generally corresponded with previously recognized marine zoogeographic regions, and cluster analyses also showed that faunal similarity among estuarine sampling sites was related to the type of sampling gear used and to the type of habitat that was sampled in each estuary. The total number of fish species reported is positively related to the size of the area …
