11,207 Abstract (Characters = 1,949) Entropy is a dimensionless quantity that is used for measuring uncertainty about the state of a system but it can also imply physical qualities, where high entropy is synonymous with high disorder.
A circular thermodynamics of organisms and sustainable systems is presented based on dynamic closures in nested space-time domains that enable the system to approach the ideal of zero entropy production simultaneously at equilibrium and far from equilibrium conditions.

A) The entropy of a system increases for a spontaneous process B) Energy can’t be created or destroyed C) For a spontaneous process, ∆Suniverse >
A subsidiary hypothesis argues that senescent decline is the combined effect of (1) uncompensated cellular attrition and (2) increasing histological entropy.
It is difficult to analyse blast waves in air at points near the explosion centre because the initial shock wave raises the entropy of the air it traverses by an amount which depends on the intensity of the shock wave.
Entropy has to increase to maximum, that’s all.” 4 “I know all about entropy,” said Adell, standing on his dignity.

The work operates a “time delineation” overcoming the logic of modernity (x = Hase) for a new art of Time circulation , or a poly-temporarily, back to Reality for herself, down to earth… Featuring the state of confusion of this times, the entropy, increased by the optical phenomenons, surrealism and eroded minimal aesthetic, the modern myth and its fictional boundaries (representation systems) is being questioned, in a variety of media with a conceptual approach.
THE CHARACTER AND SYMMETRY OF THE LIKELIHOOD FUNCTIONS OF THE SPREAD SPECTRUM SIGNALS DEMODULATION IN MOBILE ROBOTICS Abstract The purpose of the work is to obtain the probability distribution and symmetry of the likelihood functions of the variable entropy spread spectrum signals demodulation. The results have been obtained by the modelling experiments. It has been proved that the likelihood functions at the demodulator output are symmetrical and distributed normally. The obtained results prove the feasibility of using variable entropy spread spectrum signals data exchange method in the mobile robotics and give the way to build effective symbol detection tools. Keywords: spread spectrum signal, variable entropy, demodulation process, likelihood function, mobile robotics, distributed information processing system, telecommunication system.
