TLDR
This final installment of the paper considers the case where the signals or the messages or both are continuously variable, in contrast with the discrete nature assumed until now.Abstract:
In this final installment of the paper we consider the case where the signals or the messages or both are continuously variable, in contrast with the discrete nature assumed until now. To a considerable extent the continuous case can be obtained through a limiting process from the discrete case by dividing the continuum of messages and signals into a large but finite number of small regions and calculating the various parameters involved on a discrete basis. As the size of the regions is decreased these parameters in general approach as limits the proper values for the continuous case. There are, however, a few new effects that appear and also a general change of emphasis in the direction of specialization of the general results to particular cases.read more

The measurement of diversity in different types of biological collections
TL;DR: Information content may be used as a measure of the diversity of a many-species biological collection whereby the sample size is progressively increased by addition of new quadrats and the mean increment in total diversity that results from enlarging the sample still more provides an estimate of the Diversity per individual in the whole population.

FRAGSTATS: spatial pattern analysis program for quantifying landscape structure
Kevin McGarigal,Barbara J. Marks +1 more
TL;DR: McGarigal et al. as mentioned in this paper developed a spatial pattern analysis program for quantifying landscape structure called FRAGSTATS, which is almost completely automated and thus requires little technical training.

Transmission of information
TL;DR: In this article, a quantitative measure of information is developed which is based on physical as contrasted with psychological considerations, and how the rate of transmission of this information over a system is limited by the distortion resulting from storage of energy is discussed from the transient viewpoint.

Certain factors affecting telegraph speed
TL;DR: In this paper, it was shown that the wave shape depends somewhat on the type of circuit over which intelligence is to be transmitted and that for most cases the optimum wave is neither rectangular nor a half cycle sine wave as is frequently used but a wave of special form produced by sending a simple rectangular wave through a suitable network.
