This paper presents data obtained from measurements of the X2 Interpreter. The measurements were made to determine how to Increase the Interpreter's efficiency. The subroutine call operation was found to consume a significant percent of the execution time.
The Macintosh revolutionary interface sets it apart from all other personal computers. The Macintosh designers made the Macintosh easy to learn, understand, and use.
To ensure correct implementation of their User interface, Apple provided Macintosh programmers with "Inside Macintosh". Inside Macintosh is a complete detailed manual which contains recommendations and...
This document describes the design and implementation of a pair of language interfaces to a network database management system. CSDDL provides the DBMS with a data description language facility, and CSDSDL functions as a data storage description language interface of the DBMS. Source languages of CSDDL and CSDSDL are approximately...
A computer program package to estimate cable yarding
payload capability was made. The package was intended to
expand applicability of existing packages and to be user
friendly. It has six system options: live skyline, standing
skyline, running skyline, slackline, multispan and highlead.
In the standing skyline and multispan analyses, load...
Through its Policy Analysis section, the Forest Service has conducted a Long Term Training Program in Systematic Analysis (hereinafter called the Program) at Michigan State University, then later, jointly at both Michigan State and Oregon State University f or twenty years. Approximately one hundred graduates of the Program are r-ijW...
It is the purpose of this paper to explore the integration of fire management into the land planning process. Through an understanding of fire management and its effects on other forest activities, a framework may be developed for meeting both the objectives of legislation in forest management and improvement in...
In the mid 1970's, two critical forest planning directives were legislated by Congress. The Forest and Rangelands Renewable Resoures Planning Act (RPA), mandating that the U.S. Forest service undertake long-range planning initiatives, was passed in 1974. The National Forest Management Act of 1976 amended the RPA planning process. Together, these...
The prescription presented covers two stands of timber, designated Stands A and B, owned by the Wolf family. The owners seek a management plan which will coordinate activities between the stands to yield a continuous flow of wood products and income.
The objectives of this paper are to: (1) describe the structure and output of SHRUB and RMS8O, (2) evaluate their respective ability to satisfy the needs of a state level timber assessment, and (3) demonstrate their application to forest planning using the state of California as the focus of a...
The three major public forest land managing agencies In Oregon (USDA - Forest
Service, Bureau of Land Management and State of Oregon) were studied to determine
how public lands are allocated to different uses. This project looked at pertinent laws
and policies to develop an understanding of the impacts these...
Successful implementation of a forest plan depends in large part on 1) the quality of that plan, 2) the amount of public ownership in it and 3) the ability of the Forest Service to effectively involve the public in the process of putting it into action. The first two'points are...
As the population in the United States and the world grows, the demand for wood products, recreation opportunities, clean air and water, and other primary and derived forest resources will grow. Opportunities to realize each of the forest resources in a given area may be mutually exclusive, and their production...
An analysis of a proposal to designate Grant County,
Oregon, sustained yield unit status is presented. A brief
history of the Sustained Yield Act and its applications
are also included. Demographic, geographic, and economic factors are used in a comparative format, using an existing sustained-yield unit and another county of...
This paper includes a literature review of the methodologies invoked to surmount difficulties inherent with aerial photograph mensuration. The synopsis of early achievements is followed by a more intensive examination of experimental studies of the last decade, particularly the work on controlled scale photography.
This report on the pursuit of...
In the past 3-5 years, two federal agencies, the Forest Service (FS) and the National Park Service (NPS), have initiated pilot programs in concessioner-operation of developed-site government recreation facilities, specifically family campgrounds and related facilities. These programs have been generally successful by agency measure, and consequently, both agencies have modified...
This paper describes the results of a study of log
truck travel speeds in three locations in Western Oregon on
favorable grades and curves. Independent variables of grade,
curve radius, width, ditch depth, superelevation, sight
distance, time of day, and maximum engine braking horsepower
were regressed against speed. Only grade...
Tension relationships were determined in steel cable passed through a stump notch and anchored to another object. Tensions were measured in the cable coming into and leaving the notch with one full wrap on the stump. Data was collected from two sites with two test stumps (15.7 to 37.5 inches...
The Northwest timber industry is in a transition to a smallwood harvest environment. As the Northwest moves to smaller average diameter stands log values have decreased and harvest costs have increased. In an effort to increase profitability, Northwest loggers are beginning to "mechanize". The profitable operation of a mechanized harvest...
