Announcements
24 May 2018
MDPI will be represented at the ECOS 2018, held in Guimarães, Portugal, from 17–22 June, 2018.

Meet us at the ECOS 2018—The 31st International Conference on Efficiency, Cost, Optimization, Simulation and Environmental Impact of Energy Systems, from 17–22 June, in Guimarães, Portugal.
Focused on the fundamentals of thermodynamics, economics and environment analysis of all forms of energy conversion, this conference has a special session designed to transmit the view of industrial partners on energy management and conversion technologies, exchanging their experiences with the academic community. During this session, which is entitled “Industrial Challenge”, several energy intensive companies have been invited to participate, in order to establish a link between what the industry sees as the biggest challenges that can be studied and improved by the academic community.
The following MDPI journals will be represented:
If you are also attending this conference, please stop by our booth at Vila Flor Palace. Our delegates look forward to meeting you in person to answer any questions you may have regarding open access publishing or our journals. For more information about the conference, please visit: http://www.ecos2018.org/

Congratulations to Entropy for Publishing the 20th Volume in 2018
We would like to send warm wishes from the Editor-in-Chief of Entropy and look to the future. Acknowledgement of our past achievements provides the strongest stimulus for future endeavor.
As the journal Entropy enters its 20th year, one cannot help but reflect not only on how far the journal has come, but also on how far the field has come. I have been Editor-in-Chief of Entropy for the past six years, which is roughly one-third of the lifetime of the journal. While my predecessors did an excellent job in establishing the journal, I am grateful to have had the opportunity to help it grow. On my arrival in 2012, Entropy had an impact factor of 1.183. This last year, 2017, the impact factor reached a respectable 1.821 and it promises to break 2.0 in the next year or so, as Entropy continues its rapid growth.
I have been an active member of the MaxEnt (Bayesian Inference and Maximum Entropy Methods in Science and Engineering) community since I first attended the MaxEnt 1997 workshop over twenty years ago, just before the birth of the journal Entropy. My MaxEnt colleagues had long been concerned about the fact that there were few precious journals that would entertain their research papers for publication. Historically, the MaxEnt community has been known for being about a decade or so ahead of its time. While this is an exciting position to be in, it is extremely difficult from a pragmatic perspective, since it is common for the scientific community to undervalue or, worse, to misunderstand our work. We continue to encounter some of these difficulties at Entropy, since it is still frequent for the scientific community to think of entropy as a thermodynamic quantity rather than a tool for making inferences. Fortunately, as the journal continues to grow, the number of those who understand entropy grows.
I was delighted to take the helm of Entropy in 2012. I had access to a large circle of excellent scientists who had much to contribute and could profit from a growing journal with a scope to accommodate their work! Contribute they did. But I was astonished to discover so many other people out there who were applying entropic concepts to their problems. I was, and still am, excited to learn of new applications and advances and I am grateful that Entropy is in an excellent and respected position to present and showcase them.
— Prof. Dr. Kevin Knuth
Editor-in-Chief of Entropy
