Topological Sorting is a standard computation performed on finite partial order relations, for which efficient algorithms are well known.
This work is a study of using a depth-first search of a directed graph to implement topological sorting algorithms. A new algorithm is presented, along with a discussion of how it...
A computer program complexity measure is a measure of how easy the program is to understand, test, modify, maintain, etc. Many of these measures are derived from the control or flow graph of the program. We describe these measures graph theoretically, indicate what aspect or aspects of the program they...
A software system to study network algorithms was implemented on UNIX. Each part of a network algorithm can be written as a single C program which becomes a virtual node in the network. During a simulation all virtualized nodes run as separate processes on a single PDP 11/44. Inter-node communication...
A concurrency and resiliency control scheme for a distributed database system with replicated data is discussed. The scheme, true-copy token scheme, uses true-copy tokens in order to designate the physical data copies (true copies) that can be identified with the current logical data that are globally unique, and then it...
A theory for resiliency control of distributed database systems is developed, and schemes that preserve the consistent global database state in the presence of site crashes and message link failures are discussed. The schemes can at least theoretically be paired with any concurrency control scheme that produces y-serializable executions. Further,...
This document contains a summary of changes in administrations and actions taken by the Pacific Marine Fisheries Commission in 1983, as well as an update for the status of various fisheries.
Crops were grown at the experimental farms using accepted cultural practices within the limits of experimentation or trials were conducted on growers' fields. Most experiments were designed as randomized complete blocks with two to five replications. H8rbicide treatments were applied uniformly with equipment ranging from precision plot sprayers to quart...

Cooperative Forestry and Pest Management conducted a pilot control project in central Montana to determine the effectiveness of two commercial formulations of BaaiUus th,uringiensis Berliner applied at 8 billiori international units (BIU) per acre (19.8 BIU per hectare) when used under operational conditions against the western spruce budworm, Choristoneu:roa ocaidentalis...
Root disease of 2-0 western white pine seedlings occurred at the Coeur d'Alene Nursery in 1982 within seedbeds fumigated with methyl bromide and chloropicrin. Although losses were not substantial, there were several groups of dead seedlings within affected seedbeds. Fusarium oxysporum was most often isolated from diseased roots. Other Fusarium...
