X2 [4] is a Smalltalk-like programming environment [1]. As it has grown in size and complexity the existing organizational tools have become inadequate for user and system needs. This project addresses this deficiency and some of its important consequences.
The entities to be organized are those that are a fixed...
In this research paper, a ported development support tool, the MacExpert, for implementing an expert system on Macintosh will be introduced. This application is designed to allow its user to develop an expert system in a simple and user-friendly environment, the Macintosh personal computers, yet with adequate power.
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.
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...
Small, independent logging contractors can benefit
from cost control and cost planning. This report
details the labor and equipment cost components of a
logging crew. Records, both required and available for
determining costs, are discussed. Recommended costing
procedures are illustrated. Although the study took
place in the Pacific Northwest, the...
Cable yarding of first thinning size material from plantations of Pinus radiata in South Eastern Australia 15 simuiated using a computer model. Production rates, expressed in cubic metres per hour and production cost, expressed in dollars per cubic metre were derived using the model to simulate cable yarding under set...
The Pulp and Paper Industry in the Pacific Northwest is
obtaining an increasing share of its fiber supply by
chipping small diameter trees from thinnings, insect damaged
stands, and stand conversions. Since most of the mills
require pulp grade fiber to contain less than 0.5% bark, the
timber must be...
The analysis of prehistoric stone features has suffered for two separate but related reasons. The first is the lack of stringency in defining the terms attributed to these structures and, second, the perception of a lack of formal attributes exhibited by them. These two factors have made it impossible to...
It was previously shown that vaccinia virus is unable to complete its replicative cycle in cells that have been subjected to cytochalasin-B mediated enucleation prior to infection. Likewise, in the presence of the drug α-amanitin, a potent inhibitor of host RNA polymerase II but not of viral transcription, the replication...
