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...

Fungi associated with cankers of Russian-olive seedlings at the Montana State Nursery, Missoula, were investigated. Phomopsis elaeagni was most often isolated from and fruiting on cankers. Other associated fungi were Phoma herbarum, P. eupyrena, P. chrysanthemicola, P. exigua, Alternaria alternate, Epicoccum nigrum, and Fusarium moniliforme. Because of its common occurrence...
Douglas-fir beetle has increased to epidemic levels in mature-overmature Douglas-fir that has been top killed by western spruce budworm. About 42 trees per acre have been killed in an area at Lyon's Face and 36 trees per acre in other areas along the Madison River during the past 3 years....
An investment is an expenditure made with expectation of future gains, financial or otherwise. Dwarf mistletoe management, and even forest management itself, often involves investment for social and community benefits without expectations of direct financial gain. The USDA Forest Service Northern Region's dwarf mistletoe program, 1966 to 1981, is used...
Residual Douglas-fir and lodgepole pine are dwarf mistletoe-infested and pose a threat to existing regeneration. Felling or girdling these residuals, along with sanitation/thinning of dense patches of regeneration, will reduce dwarf mistletoe intensity and increase future volume yields. Present net worth of the projects ranges from -$1 to $39 per...
Residual Douglas-fir, western larch, and lodgepole pine are dwarf mistletoe-infested and pose a threat to existing regeneration. Felling or girdling these residuals, along with sanitation/thinning, will reduce mistletoe intensity and increase future volume yields. Present net worth of the project is $48.05/acre. Benefit cost ratio is 1.97/1. Use of pest...
For the fourth year since their establishment, the six permanent plot locations in Montana were revisited following beetle flight in 1982.Beetle populations remained low in five of the six areas. Only in the Murr Creek plots did newly attacked trees represent an epidemic beetle population. In the Centennial Valley location,...
This report includes information concerning experimental use of unregistered pesticides or unregistered uses of pesticides. Experimental results should not be interpreted as recommendations for use. Use of unregistered materials or use of any registered pesticides inconsistent with its label is against both Federal Law and State Law.
My experiences with the U.S. Army Corps of Engineers (referred to as the Corps) has been an integral part of my formal education. My work with the Corps fulfills my internship requirement for my Masters Degree in Marine Resource Management. The work here has allowed me to use my academic...
A study of precipitation and yield levels in fallow-wheat rotations at three
Pacific Northwest locations demonstrated that in the Columbia Plateau region,
the variability and skewness of precipitation increased with decreasing mean
amounts of precipitation. The seasonal distribution of precipitation had a
marked effect on wheat yield. Comparisons of precipitation...
CTD observations were made in the CODE region between Pt. Arena (39°N) and Pt. Reyes (38°N) during 28 February - 1 March 1982. The observations were made along three sections: the Arena Line, the North Line and the Code Central Line. An additional single CTD cast was made off Eureka...
This is a listing of both PhD and Master's· theses relating to the areas of forestry issued during the period from July 1976 to June 1981. The
list is arranged first by state, then by college or university within each state. Authors of theses are arranged alphabetically under each of...
Reports on private Chinook, chum and coho salmon hatcheries in Oregon. Includes statistics and a map showing hatchery locations. "This report provides information on developments, shows progress in 1982, and summarizes production and return information." (from the Introduction)
