EVOLUTION AS PHYSICS
Journal Title: ROMANIAN JOURNAL OF TECHNICAL SCIENCES - APPLIED MECHANICS - Year 2017, Vol 62, Issue 1
Abstract
Thermodynamics today is the physics domain in which three previously selfstanding lines of thinking merged to cover the broadest range of natural phenomena to date. The three lines were work-heat-design, or mechanics-caloric-evolution. Covered now as ‘physics’ are the previously separate domains of biology, technology, economics, and social organization. The purpose of this brief article is to outline this broad coverage by drawing attention to the new terms, physical properties, and concepts that have crept into physics, for example: freedom, evolution, performance, objective, purpose, better, design, configuration, optimization, complexity, diversity, hierarchy, size, wealth, equality, and economies of scale. Along the way, I clarify some of the most common misconceptions that persist in this expanded domain of physics In sum, this is a brief look at the evolution of thermodynamics and how the traditional concept of ‘evolution’ itself fits in this new scientific framework.

PROPERTIES OF THE ENTROPY AND INFORMATIONAL ENERGY FOR THE SOLUTIONS OF BLACK-SCHOLES EQUATIONS
This paper studies the properties of the solutions of some stochastic differential equations and Black-Scholes type equations, in the n-dimensional case Rn, from the point of view of informational energy and entropy asso...
RISK-TARGETED MAPS FOR SEISMIC DESIGN. A BRIEF REVIEW OF THE STATE-OF-THE-ART
The uniform hazard approach is currently used for almost all seismic design maps enforced worldwide. That being the case, the seismic risk of buildings designed according to uniform hazard values of ground motions parame...
A VIRTUAL INTERNAL BOND MODEL FOR HYSTERETIC MEDIA
In this paper, the properties of the hysteretic media are investigated via the virtual internal bond model (VIB) derived from the hyperelasticity with the integration of the 6–12 Lennard-Jones atomic interacting potentia...
DYNAMICS OF A 2-DOF ORIENTING GEAR MECHANISM
Recursive matrix relations for the kinematics and the dynamics analysis of a 2-DOF orienting gear train are established in this paper. The mechanism is a parallel system with five moving links and three bevel gear pairs...
DYNAMICS MODELLING OF A PARALLEL FLIGHT SIMULATOR
Recursive matrix relations for dynamics analysis of a parallel manipulator, namely the spatial flight simulator, is established in this paper. Knowing the general motion of the platform, the inverse dynamics problem is s...
