Citation of constructal related publications still in rise in the S-shaped curve

Citation of constructal related publications still in rise in the S-shaped curve | Constructal Law of Design in Nature | Scoop.it

The updated indices of constructal related works in

qualified peer-review publications. The chart shows the number of citations per year.

 

h-index: 50

(excerpt from Thomson-Reuters® web of science with "constructal" as topic)

Marcelo Errera's insight:

 

The accumulated qualified citations since 1996 surpassed the 11,000 barrier. The trend is that the number of citations increases every year.

 

The number of articles without self-citations increased in 25% only last year !  Newer researchers in newer fronts as the field takes its natural course of spreading.

You can use physics to describe almost anything in life

You can use physics to describe almost anything in life | Constructal Law of Design in Nature | Scoop.it

Think of physics and you most likely picture clearly defined, specific systems: atoms interacting, equations involving force, mass, and acceleration, and recent discoveries such as the Higgs boson or gravitational waves. But why should physics be limited to such topics? 

(...)

In simpler language, all living systems will naturally move into configurations that allow for easier movement. It sounds deceptively straightforward, but Bejan has used his theory to discover behavior in both the natural world and manmade constructs, with these findings published in highly-regarded journals.

Marcelo Errera's insight:
Any attempt to describe the world around us is valid.  The scientific method will filter them once they become public. Scientific Revolutions often come with some transgressions to status-quo.

Why Physics Is Not a Discipline 

Why Physics Is Not a Discipline  | Constructal Law of Design in Nature | Scoop.it

Saying that physics knows no boundaries is not the same as saying that physicists can solve everything. They too have been brought up inside a discipline, and are as prone as any of us to blunder when they step outside. The issue is not who “owns” particular problems in science, but about developing useful tools for thinking about how things work—which is what Aristotle tried to do over two millennia ago. Physics is not what happens in the Department of Physics. The world really doesn’t care about labels, and if we want to understand it then neither should we.

The Physics of Life, The Evolution of Everything, is Prof. Adrian Bejan last book, and will be released May, the 24th.



(...)"While it may take a careful rereading of certain chapters to truly grasp the author’s novel unifying theory, it is worth the effort, as his book-length proof is at once riveting and poetic. Rarely are scientists capable of translating esoteric concepts in such broad strokes without losing coherence, but Bejan’s persistent focus on the details brings the constructal law to life via the everyday. In the end, his blend of science and the philosophy of design (among other disciplines) is convincing and may just shift your perspective of self."(...)

How Diversity Makes Us Smarter

How Diversity Makes Us Smarter | Constructal Law of Design in Nature | Scoop.it

Decades of research by organizational scientists, psychologists, sociologists, economists and demographers show that socially diverse groups (that is, those with a diversity of race, ethnicity, gender and sexual orientation) are more innovative than homogeneous groups.
It seems obvious that a group of people with diverse individual expertise would be better than a homogeneous group at solving complex, nonroutine problems. It is less obvious that social diversity should work in the same way—yet the science shows that it does.
This is not only because people with different backgrounds bring new information. Simply interacting with individuals who are different forces group members to prepare better, to anticipate alternative viewpoints and to expect that reaching consensus will take effort.

How Do You Say “Life” in Physics? | Constructal Law of Design in Nature | Scoop.it

We think we know life when we see it. Darwin’s theory even explains how one form of life evolves into another. But what is the difference between a robin and a rock, when both obey the same physical laws? In other words, how do you say “life” in physics? Some have argued that the word is untranslatable. But maybe it simply needed the right translator.

Optimization of drinking water distribution networks: Computer-based methods and constructal design

by P. Bieupoude, Y. Azoumah, P. Neveu

    A well-known application of water engineering is drinking water distribution through pipe networks in urban and rural areas. The present work addresses this issue with a specific focus on the network design. First, the paper presents a brief review of computer-based design methods and shows that a significant number of efforts have been pursued. Secondly, it proposes the approach of geometric analysis of the dis- tribution networks as complementary points of the former optimization methods. Finally, an original illustrative application is proposed. The geometric and multi-scale optimization known as the constructal design is used to analytically optimize T-shaped network architectures subject to an operational water quality constraint. This illustrative application leads to the determination of an optimal geometry of the network that minimizes head losses (factor of pumping energy

Universal resilience patterns in complex networks

Universal resilience patterns in complex networks | Constructal Law of Design in Nature | Scoop.it

Resilience, a system’s ability to adjust its activity to retain its basic functionality when errors, failures and environmental changes occur, is a defining property of many complex systems. Despite widespread consequences for human health, the economy and the environment, events leading to loss of resilience—from cascading failures in technological systems to mass extinctions in ecological networks—are rarely predictable and are often irreversible. These limitations are rooted in a theoretical gap: the current analytical framework of resilience is designed to treat low-dimensional models with a few interacting components, and is unsuitable for multi-dimensional systems consisting of a large number of components that interact through a complex network. Here we bridge this theoretical gap by developing a set of analytical tools with which to identify the natural control and state parameters of a multi-dimensional complex system, helping us derive effective one-dimensional dynamics that accurately predict the system’s resilience. The proposed analytical framework allows us systematically to separate the roles of the system’s dynamics and topology, collapsing the behaviour of different networks onto a single universal resilience function. The analytical results unveil the network characteristics that can enhance or diminish resilience, offering ways to prevent the collapse of ecological, biological or economic systems, and guiding the design of technological systems resilient to both internal failures and environmental changes.

Neither Maximum nor Minimum Entropy Production, just Constructal Law - a strong argument

It is shown how both the principles of extremum of entropy production, which are often used in the study of complex systems, follow from the maximization of overall system conductivities, under appropriate constraints. In this way, the maximum rate of entropy production (MEP) occurs when all the forces in the system are kept constant. On the other hand, the minimum rate of entropy production (mEP) occurs when all the currents that cross the system are kept constant. A brief discussion on the validity of the application of the mEP and MEP principles in several cases, and in particular to the Earth’s climate is also presented.
Marcelo Errera's insight:
It seems the arguments presented by Antonio Reis set the issue whether it's maximum or minimum entropy production that drives design evolution. It's neither one of them: it's the Constructal Law.

Why Nature Prefers Hexagons

Why Nature Prefers Hexagons | Constructal Law of Design in Nature | Scoop.it

"How do bees do it? The honeycombs in which they store their amber nectar are marvels of precision engineering, an array of prism-shaped cells with a perfectly hexagonal cross-section. The wax walls are made with a very precise thickness, the cells are gently tilted from the horizontal to prevent the viscous honey from running out, and the entire comb is aligned with the Earth’s magnetic field. Yet this structure is made without any blueprint or foresight, by many bees working simultaneously and somehow coordinating their efforts to avoid mismatched cells."

The social gene

The social gene | Constructal Law of Design in Nature | Scoop.it
Genetic research has moved rapidly since the publication of Richard Dawkins's The Selfish Gene 40 years ago. In the intervening years, we have come to realize that many of the most interesting and important phenomena in human biology are not caused by any single gene. Citing a wealth of recent research that explores the ways genes work together to produce complex biological processes, Itai Yanai and Martin Lercher argue that it is time to embrace a new, more holistic, metaphor in their book, The Society of Genes.

Design and Science

For me, antidisciplinary research is akin to mathematician Stanislaw Ulam’s famous observation that the study of nonlinear physics is like the study of “non-elephant animals.” Antidisciplinary is all about the non-elephant animals.
I believe that by bringing together design and science we can produce a rigorous but flexible approach that will allow us to explore, understand and contribute to science in an antidisciplinary way.

NigelReading|ASYNSIS's curator insight, March 3, 10:24 AM
The principle of least action/energy, analogical (self-similar), optimal feedback loops, & irreversibility (the arrow of time), all lead to these dynamical symmetries of information flows & geometric forms.
Another way of referring to gravitational "tension" is gravitational "potential energy" or even gravitational "entropy-production".
We now know that QM entanglement entropy is equivalent to spacetime curvature (linked by computational complexity universality - ER=EPR theory), so Adrian Bejan is absolutely correct.
Entropy production (and complexity) is maximised when we have a hierarchy of masses in the universe.
This increased complexity speeds the universe more easily & rapidly towards thermal equilibrium.
Just as a comet is more interesting than an asteroid, our universe chooses a more complex path, most simply.
