Wood properties and use of sensor technology to improve optimal bucking and value recovery of Douglas-fir

Creator:: Acuna, Mauricio A.
Abstract:: There are a number of wood properties which affect the quality of forest products such as lumber and pulp. Of these, wood density is considered by some to be the single most important physical characteristic because it is an excellent predictor of strength, stiffness, hardness, and paper-making capacities. Accurately assessing...

An investigation of factors affecting the optimal output log distribution from mechanical harvesting and processing systems

Creator:: Marshall, Hamish Douglas
Abstract:: Globally the forest harvesting industry is becoming increasingly mechanized. Driving this trend is the desire to increase productivity and reduce cost, as well as to improve labor-related issues. With mechanization comes an in-forest platform for the introduction of state-of-the-art communication and measurement technologies, and powerful on-board computers. These systems have...
