Flood of June 9, 1957, at Perry, Florida
Floods occurred on streams in the vicinity of Perry,
Taylor County, Florida, on June 9, 1957, as a result of heavy
rains from atropical disturbance. Serious flooding occurred
in Perry along Spring and Pimple creeks as outlined by the
shaded area in figure 1, requiring the evacuation of about
ZOO families from the lowland area. No loss of life was
reported. The damages to residential and commercial properties
were estimated at several million dollars. Most of
the damage was confined to residential areas (fig. 2); however,
several stores in the area were damaged by flood
waters (fig. 3).
This report presents data pertaining to the rainfall
accompanying this storm and peak flows of Spring and Pimple
creeks in Perry. It contains flood elevations at several
points, and peak discharges of the two creeks flowing through
Perry. The report also contains a discussion of the rainfall
associated with the flood and a description of the general
features of the flood. (PDF contains 16 pages.
The Eccentuator: A new concept in actuation
A new concept in actuation for aerospace mechanisms is presented. This actuator, called an 'eccentuator', features unique output characteristics, installation and envelope efficiencies, and relative simplicity. The actuator can be powered by either hydraulic or mechanical inputs. Potential applications of the 'eccentuator' and development efforts are discussed

Knowledge representation for basic visual categories
This paper reports work on a model of machine learning which is based on the psychological theory of prototypical concepts. This theory is that concepts learnt naturally from interaction with the environment (basic categories) are not structured or defined in logical terms but are clustered in accordance with their similarity to a central prototype, representing the "most typical'' member

A.I. approaches in statistics
The role of pattern recognition and knowledge representation methods from artificial Intelligence with in statistics is considered. Two areas of potential use are identified and one, data exploration, is used to illustrate the possibilities. A method is presented to identify and seperate overlapping groups within cluster analysis, using an A.I. approach. The potential of such 'intelligent' approaches is stressed

A prototypical approach to machine learning
This paper presents an overview of a research programme on machine learning which is based on the fundamental process of categorization. This work draws upon the psychological theory of prototypical concepts . This theory is that concepts learnt naturally from interaction with the environment (basic categories) are not structured or defined in logical terms but are clustered in accordance with their similaritry to a central prototype, representing the "most typical" member.
A structure of a computer model designed to achieve categorization is outlined and the knowledge representational forms and developmental learning associated with this approach are discussed
Water resource records of the Econfina Creek Basin area, Florida
The Econfina Creek basin area in northwestern Florida, which includes Bay
County, southeastern Washiigton County, and parts of Calhoun, Gulf, and
Jackson counties is shown in figure 1. The basin has an abundant supply of
ground water and surface water of good quality. This determination is based on
a three-year investigation of the water resources of the basin by the U. S.
Geological Survey in cooperation with the Division of Geology, Florida Board of
Conservation, during the period from October 1961 through June 1964. The
purpose of this report is to assemble the basic data collected during this
investigation for those persons interested in water development or management
in this basin.
