The
Smith Chart
The Smith Chart was originally created many years ago as an RF
engineering aid by Phillip Smith of RCA. Actually, Smith may not
have been the first inventor of this tool -- a Japanese engineer
named Kurakawa independently created a similar chart about a
year before Smith. In any event, the Chart is a clever, complex
number nomograph in a circular format which is an invaluable
tool in RF design...

A
brief introduction to nomography: graphical representation
of mathematical relationships
Leslie
Glasser & Ron Doerfler
Nomographs (or nomograms, or alignment charts) are graphical
representations of mathematical relationships (extending to
empirical relationships of data) which are used by simply
applying a straightedge across the plot through points on scales
representing independent variables, which then crosses the
corresponding datum point for the dependent variable; the choice
among independent and dependent variable is arbitrary so that
each variable may be determined in terms of the others. Examples
of nomographs in common current use compute the lift available
for a hot-air balloon, the boiling points of solvents under
reduced pressure in the chemistry laboratory, and the relative
forces in a centrifuge in a biochemical laboratory. Sundials
represent another ancient yet widely familiar example. With the
advent and ready accessibility of the computer, printed
mathematical tables, slide rules and nomographs became generally
redundant. However, nomographs provide insight into mathematical
relationships, are useful for rapid and repeated application,
even in the absence of calculational facilities, and can
reliably be used in the field. Many nomographs for various
purposes may be found online. This paper describes the origins
and development of nomographs, illustrating their use with some
relevant examples. A supplementary interactive Excel file
demonstrates their application for some simple mathematical
operations.

Abstract
This work deals with the dimensioning of multi-packed-bed
dehumidifiers used in solar air-conditioning systems. An
efficient dimensioning methodology is elaborated, explained and
visualized by a chart. The proposed methodology permits to
ensure an appropriate packed-bed dimensioning based on a
compromise between the highest possible amount of heat and mass
transfer and the lowest possible level of pressure drop within a
packed-bed-dehumidifier. Nomography tool is implemented in order
to simplify, speed up and expand the possibilities of
dimensioning. The proposed nomographs permit to determine the
appropriate values of the diameter, the porosity and the height
of the packed-bed. The mathematical construction techniques of
all nomographs are presented in detail. Applied examples are
carried out in order to show the effectiveness of each
nomograph.

Abstract
Traditionally, history of mathematics was more interested in the
production of abstract concepts and major theories than in the
one of methods and tools of calculation. As a result, it has
often neglected to consider the mathematical practices of
engineers. I want to sketch here a sample of these practices
through the example of nomography in the second half of 19th
century and first half of the 20th century, precisely at the
time when the professional community of engineers structures
itself and deepens its mathematical culture.

FIELD:
seismology. ^ SUBSTANCE: invention relates to the field of
seismology and can be used for predicting tsunamis. Seismic
signals are registered from earthquakes by seismographs, located
in the peaks of equilateral triangles on bed rock. They
determine the time the seismic signals were caused, the distance
using triangulation. They measure the speed of the longitudinal
and diametric waves in the volume of rock in the disposition of
the triangle. The read the seismic signals from the earthquake.
They measure the time of the delay. They determine using the two
minimum times of the delay the azimuthal angles between the norm
to the front of the seismic wave, occurring through the centre
of the triangle, the epicenter of the earthquake, and the given
initiating point of the report. The precise location of the
epicenter of the earthquake, the magnitude of the temporal delay
for the horizontal plain (surface of the earth), the angle of
the location of the focus, the distance, the focus, the distance
to the epicenter, the depth of the focus are calculated. At the
seismic monitoring station with the aid of a computer the
maximum magnitude of the observed underwater earthquake is
calculated in microns or seismograms. The magnitude (M) is then
calculated according to the Richter scale using a nomograph. If
MëÑ7 then the conclusion is that a tsunami is possible. To
confirm the accuracy of the information a check is carried out
on the presence of tsunami waves with the help of information
received by radio from a device for determining tsunami waves,
located in the ocean in the proximity of contact between the
lithosphere plates or the break in the earth's core.
Furthermore, information is taken and analysed about the wave's
movements from the surface to the seabed at a speed of 700-900
km/hour. The force of wave pressure is taken into account. The
height of the tsunami wave is taken into account on its approach
to the shore line. The time of the approach of the tsunami to
the shoreline is calculated and the population informed. ^
EFFECT: increased responsiveness and accuracy in determining
tsunamis.

COMBINED
OVAL SLIDE RULE AND NOMOGRAPH
[ PDF ]
A calculating
device comprising a flat generally oval-shaped card member
having a perimeter defining somewhat semicircular sections
interconnected by a central elongated section. The central
section is formed of a generally straight periphery. A pair of
indicating arms are rotatable about a pivot point on the member.
The pivot point may be along the longitudinal axis of the card
member, and offset from the center of the member. In addition, a
scale may be printed on one side of the periphery of the member.
Moreover, the semicircular sections can be identical in size,
and a scale printed on the other side of the member and adjacent
the periphery of the member may be the reciprocal of the scale
on the first side. In addition, the calculating device may be
used as a loan payment computer for determining the periodic
payments due on a predetermined loan. By providing the card
member with a plurality of interest rate curves which are
juxtaposed with a plurality of loan duration curves, the scale
may be representative of periodic payments. Thus, by positioning
one of the indicia arms at the intersection of the desired
interest rate and loan duration, the resultant position on the
scale would be representative of the periodic payment for the
intersecting interest rate and loan duration.
