A carburetor, such as is used on a gasoline engine, is
an appliance for vaporizing liquid hydrocarbons by atomizing
the liquid and mixing it with air.
This mixture of gasoline vapor and air is drawn into
the cylinder of'a gasoline engine, compressed and exploded
by means of an electric spark;...
In this paper the characteristics of multi-conductor transmission
lines have been investigated for a variety of termination conditions
by using the differential equations and matrix methods.
Equations showing the characteristics of traveling waves along loss-less
multi-conductor systems are derived.
Line parameters were evaluated by experiments and by calculations.
The results...
In this paper, we use an interactionist perspective to study inter-industry variation in buying behavior. We argue that individual purchasers’ preferences for suppliers depend on three broad classes of variables: (1) The structure of the value chain stage in which the firm competes, (2) the firm’s competitive strategy and (3)...
The operation of a tunnel-diode delay-line memory cell is
examined in some detail, and a digital computer program which
approximately simulates the operation of this memory cell is developed.
The data from the computer simulation is compared with the
available experimental data and found to agree very closely for clock...
Recent acheivements in high speed digital integrated
circuits has prompted the system designers to search for
a practical method of inter-connecting these high speed
circuits. This paper describes the implementation of the
microstrip transmission line on a high speed digital
data bus. Transmission line and characteristic impedance,
termination with single...
The purpose of this pilot study was to determine whether students
using a series of planned exercises designed to improve typewriter
composition skills would be better able to compose at the typewriter
than students in a control group. The study was also concerned with
the effect that the use of...
A computationally efficient algorithm has been developed for
determining exact or approximate solutions for large scale generalized
fixed charge problems. This algorithm is based on a relaxation
of the Benders decomposition procedure, combined with a linear
mixed integer programming (MIP) algorithm specifically designed to
solve the problem associated with Benders...
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...
