The primary objective of the study was to develop the methodology to identify broad silvicultural treatment opportunities for nonindustrial private (NIP) timberland in western Montana using Forest Survey data. The study assumes a management goal of maximum volume production at the stand level. The purpose of the stand treatments is...
In this paper, we introduce a model-based reinforcement learning method called H-learning, which optimizes undiscounted average reward. We compare it with three other reinforcement learning methods in the domain of scheduling Automatic Guided Vehicles, transportation robots used in modern manufacturing plants and facilities. The four methods differ along two dimensions....
This book provides an illustrated guide to the identification and management of fungi, insects, and abiotic conditions that cause problems in Northwest bareroot conifer nurseries. A key to nursery pests offers initial guidance in identification. Separate chapters address individual pests with details on recognition, damage cycle, and management practices to...
A generalized arithmetic package allows a programmer to think of numbers as abstract quantities, without regard to whether they are represented as integers, floating point values, fractions, complex numbers, or even polynomials. In this paper we describe two implementation techniques that can be used to produce a generalized arithmetic package...
Multiparadigm programming languages have been envisioned as a vehicle for constructing large and complex heterogeneous systems, such as a stock market exchange or a telecommunications network. General-purpose multiparadigm languages, as opposed to hybrid multiparadigm languages, embody several prevalent programming paradigms without being motivated by a single problem. One such language...
We consider learning tree patterns from queries extending
our preceding work [Amoth, Cull, & Tadepalli,
1998]. The instances in this paper are unordered
trees with nodes labeled by constant identifiers.
The concepts are tree patterns and unions
of tree patterns (unordered forests) with leaves labeled
with constants or variables. A...
In order for autonomous underwater vehicles to be successful, they must be able to maintain accurate information about their state variables and the state of their critical components. The software developed by Bruce D'Ambrosia and Wade Brittain, (Real-time Tracking and Probabilistic Assessment of Physical Systems) proposes a methodology to provide...
Equations for predicting individual-tree height growth per 5-year period are presented for Douglas-fir, white fir, grand fir, ponderosa pine, sugar pine, and incense-cedar growing in the mixed-conifer zone of southwest Oregon. The data used to develop the equations came from 3,648 trees sampled from 391 stands in the study area....
Parallel languages rarely specify parallel I/O constructs, and existing commercial systems provide the programmer with a low-level I/O interface. We present design principles for integrating I/O into languages and show how these principles are applied to a virtual-processor-oriented language. We show how machine-independent modes are used to support both high...
We describe a software mechanism that simplifies the implementation of real-time distributed object-oriented applications. The distributed observable/observer mechanism extends the Observable/Observer concept of Java to a distributed environment, encapsulating the communication protocol used by networking. The mechanism supports the distributed model/view-controller (M/VC) paradigm, allowing view-controllers to be attached to remote...
