Fingered robot hands are complicated systems made of three essential system components: its morphology, its actuation, and its software control. These system components are tightly coupled to each other. Due to this, it is hard to benchmark robot hand performance in a way to understand the contributions of the individual...
In this paper, we provide a thorough proof of most of Bertrand's Theorem. Using Arnold's book "Mathematical methods of classical mechanics" as a backbone and calculus methods demonstrated by Jovanović in his article "A note on the proof of Bertrand's theorem," we show that for masses in a central field...
Soft robotics utilizes compliant materials (such as rubber) to make robots that are flexible and safe around humans, however these materials present many practical manufacturing challenges. Current fabrication methods use molding techniques which limits the soft robot designs which could be fabricated and impacts part consistency. This defense introduces a...
Quercus garryana dominated plant communities are found in
the interior coastal valleys and on foothills from southeastern
Vancouver Island, British Columbia, south to San Francisco,
California. They occur as savannas, intermixed with a variety of
conifers, and in almost pure stands. The diversity of habitats
occupied by the species and...
A study was conducted to determine what effects the type of
pollutants, storage conditions, storage time, and method of sample
conditioning have on the reported weight of an air pollutant collected
by filtration. Samples were collected from a refuse dump, an arc
furnace smelting nickel ore, and a rotary kiln...
The purpose of this study is to review Pennsylvania's
use of paper money through two distinct periods: the first
seven years of currency issues starting in 1723 and
concluding in 1730, and the second period encompassed by
the French and Indian War in 1755-63. They represent two
significant periods affecting...
State and federal aid payments to local governments have grown explosively over the last fifteen years. One reason for this growth is that the donor governments can alter a local government's budget choices through grants. Grants have not remedied social problems, however, because the local governments' responses to grants were...
Two-year-old ponderosa pine (Pinus ponderosa Laws.)
from two seed sources were grown at two nurseries. The
Fremont seed source was raised at Bend and Stone Nursery;
the Ochoco was grown at only the Bend Nursery. The
seedlings were fertilized in late September-early October
with nitrogen (N) or nitrogen plus potassium...
This study is composed of two parts. Section I deals with
developed moorages and marinas--where they are; what services are
offered in each, and how well the existing supply of permanent moorages
serves the boating public. Section II examines the need for temporary
'harbors of refuge' in the area, what...
