A circuit topology for high-swing, high-linearity
CMOS operational amplifiers has been developed. The
technique uses parallel-connected p- and n-channel
input pairs to realize an input common-mode voltage
range nearly equal to the total power supply voltage.
High linearity is achieved by summing the DC bias and
AC small-signal currents so...
The main objective of this research was to compare the demand and
the price of hard red winter (HRW) wheat and white wheat (WW) to
determine the similarities and the differences between these two wheat
classes.
Using Granger's causality test with average monthly cash prices
and daily Free on Board...
An analytical algorithm to formulate a sparser set of adjacency constraints than the conventional algorithm is proposed. Utilizing matrix algebra applied to an adjacency matrix, constraints are systematically and efficiently derived by the proposed algorithm. The proposed algorithm is proved to provide a true set of adjacency constraints in the...
A cost function characterizes a firm's cost-minimizing behavior. It is defined
as a function of the level of outputs produced and the prices of factors which enter
the production process. Econometric estimation of a cost function allows one to test
hypotheses regarding the structure of cost and the structure of...
This study is an ethnographic investigation of residential turnover, organizational memory, and the persistence of Lost Valley, an Oregon ecovillage founded in 1989. Literature on organizational turnover, memory, and persistence is reviewed and integrated with scholarship on intentional communities and ecovillages, generating a theoretical framework for data collection and analysis....
This study was conducted in the old-growth forests of Clatsop,
Tillamook, and Lincoln counties, Oregon. The three objectives of
the research were to describe and classify the near-climax plant
communities found within the forests, to relate the associes described
by a previous study to the forest communities characterized by the...
