Negentropy analysis of surface electromyogram signal
IEEE/SP 13th Workshop on Statistical Signal Processing, 2005, 2005This study deals with measuring the non-Gaussianity in surface electromyogram signal (sEMG). The signal was obtained from biceps brachii muscle during elbow flexion at four different levels of maximum voluntary contraction (MVC). Typically the sEMG generated from constant-force, constant angle, non-fatiguing contractions is modelled as a stochastic ...

Nonlinear Diffusion, Negentropy and Restoration of Mammographic Images
2005 IEEE Engineering in Medicine and Biology 27th Annual Conference, 2005Diffusive iterative filtering may be used to restore mammographic noisy images. Assuming that images are corrupted by additive gaussian noise, the negentropy as a statistical measure of the nongaussianity, can be used to estimate the amount of noise removed from noisy images. In particular, the evolution of the negentropy with the iterations is used to

The Negentropy Principle of Information
Journal of Applied Physics, 1953The statistical definition of information is compared with Boltzmann's formula for entropy. The immediate result is that information I corresponds to a negative term in the total entropy S of a system. S=S0−I. A generalized second principle states that S must always increase.

Schrödinger’s Negentropy Concept and Biology
1992To ask a biologist to contribute to a discussion on a physicist is a bold step. Don’t we ron the risk of hopelessly confusing the issue? We can only hope that the topic at hand has remained unclarified precisely because too few biologists and physicists have talked to one another.

Time's Arrow and Feeding on Negentropy
Nature, 1967MY article, “Time's Arrow and Entropy”1, has produced so far only one voice of dissent, Professor Buchel's letter2. This letter consists of three paragraphs, to which I shall reply in order.

Radiation and Entropy, Coherence and Negentropy
1977The problem of entropy of radiation was first treated by Max Planck in the years 1895 – 1900. He considered himself as a disciple of Clausius, the founder of thermodynamics, the man who had introduced the concept of entropy into physics. Planck’s aim, when he began his research of black body radiation, was to establish an expression for the entropy of ...
