Models designed to predict when and how the roads of Bizkaia will deteriorateA researcher at the UPV/EHU's Faculty of Engineering-Bilbao has developed behaviour models of the international roughness index (IRI) and the coefficient of transverse friction to predict the future situation of the highway network of Bizkaia. The models provide the chance to predict highway repairs, to consider the type of repairs that need to be carried out and to optimize budget allocations.

It is based on a nontrivial Markov chain. In addition to the obvious practical applications of the results for the organization of servers and data centers, the theoretical part will be useful for the theory of queues and queuing, as well as for working with big data and neural networks. The study is published in the journal Mathematics.

Such theorems are very rare for partial differential equations. The new results can be applied in fields such as astrophysics, for instance, in describing the propagation of plane waves in plasma. The article is published in the journal Nonlinear Analysis: Real World Applications.

Mathematics Fri, 20 Sep 2019 03:11:27 EDTnews488167879Mathematicians proposed an express method for calculation of the propagation of lightMathematicians from RUDN University and the Nuclear Safety Institute of the RAS (NSI RAS) have proposed a numerical method for solving equations describing the propagation of light in a medium. They used the nonlinear eikonal equation with boundary conditions as the basis. Such a problem cannot be solved directly, so the mathematicians developed a numerical method, performed calculations, and produced a picture of the "behavior" of such solutions. The results could become the basis for a comprehensive theory of approximate solutions of such differential equations. The method can be applied in the production of lenses and optical crystals. The article was published in the Journal of Computational and Applied Mathematics.

Mathematics Wed, 10 Jul 2019 08:59:25 EDTnews481967944Expert mathematicians stumped by simple subtractionsMathematical thought is seen as the pinnacle of abstract thinking. But are we capable of filtering out our knowledge about the world to prevent it from interfering with our calculations? Researchers from the University of Geneva (UNIGE), Switzerland, and the University of Bourgogne Franche-Comté, France, have demonstrated that our ability to solve mathematical problems is influenced by non-mathematical knowledge, which often results in mistakes. The findings, published in Psychonomic Bulletin & Review, indicate that high-level mathematicians can be duped by some aspects of their knowledge about the world and fail to solve primary school-level subtraction problems. It follows that this bias needs to be factored into the way mathematics is taught.

Mathematics Tue, 18 Jun 2019 07:14:46 EDTnews480060876The hidden structure of the periodic systemThe periodic table of elements that most chemistry books depict is only one special case. This tabular overview of the chemical elements, which goes back to Dmitri Mendeleev and Lothar Meyer and the approaches of other chemists to organize the elements, involve different forms of representation of a hidden structure of the chemical elements. This is the conclusion reached by researchers at the Max Planck Institute for Mathematics in the Sciences in Leipzig and the University of Leipzig in a recent paper. The mathematical approach of the Leipzig scientists is very general and can provide many different periodic systems depending on the principle of order and classification—not only for chemistry, but also for many other fields of knowledge.

The continuous gentle, wavy hills and wide valleys of the Carpathians, Appalachians or lower parts of the Alps contrast strongly with the soaring peaks, ragged ridges and deep ravines of the high Tatra mountains and Pyrenees, which are, in turn, different from the inaccessible, snow-covered Himalayan or Andean giants, along whose slopes flow long tongues of glaciers instead of water. Beneath this great diversity, however, lies a surprisingly similar structure.
