Perceived objectives and values of the forest service long term training program in systematic analysis

Creator:

Miller, Larry

Abstract:

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...

Resource Type:

Capstone Project
A comparison of forest practices acts in Oregon and California

Creator:

Reis, Jeffrey Curtis

Abstract:

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...

Capstone Project
Mechanical brush control on steep slopes in southwest Oregon

Creator:

Steffan, Daryl Joseph

Abstract:

In this paper the extent of the steep slope brush conversion problem will be estimated. Potential solutions and development should be commensurable with the extent of the problem. The state-of-the-art of steep slope site preparation and conversion will be described. Feasible alternatives to these limited options will be developed.

Resource Type:

Capstone Project
Predicting running skyline performance based on the mechanical capability of the yarder

Creator:

Wilbanks, Samuel James

Abstract:

The objective of this paper is to develop a methodology for determining running skyline yarder performance based on the mechanical characteristics of the yarder and its interaction with the load and the terrain. A code for implementing this procedure on the HP-9020 will be prepared .

Resource Type:

Capstone Project
An analysis of forces and conditionswhich influence the successful passageof a carriage over an intermediate support jackduring downhill multi-span logging

Creator:

Bobbe, Thomas J.

Abstract:

In this paper, a catenary analysis of static skyline, mainline and haulback cable tensions just prior to an unsuccessful attempt by a carriage to pass an intermediate support jack is presented. Field tests were conducted for a range of skyline deflections and span chord slopes. Data collected during the field...

Capstone Project
Pendulum balloon logging system : dynamic model

Creator:

Beary, Gregory L.

Abstract:

The purpose of this paper is to determine the dynamic tensions that occur in the guylines and pendulum lines of a tethered logging balloon. A scale model was used to represent the tethered logging balloon. During the swinging of payloads, line tensions followed a very predictable sinusoidal curve. It was...
