Why Conflicts Arise? A New Relationship Cycle In Typology

Why conflicts arise? Who knows the real logical cause why people fight and hate each other? Psychologists, sociologists and other people still don’t know what is the root cause of such issues…

On an Initial Value Problem Describing the Small Oscillations of a Floating Cylinder

We study a coupled PDE-ODE system modeling the small oscillations of a floating cylinder interacting with small water waves. We consider the case when the floating is supposed to be an infinite circular cylinder, so that the equations of the free surface of the fluid can be written in one space dimension. The governing equations are formulated as an abstract evolution equation in a suitable Hilbert space, and we establish the well-posedness of the associated initial value problem. A key element of the proof is the analysis of a partial Dirichlet-to-Neumann map on an unbounded domain with a non-smooth boundary.

Crows can recognize geometric regularity

A trio of animal physiologists at the University of Tübingen, in Germany, has found that at least one species of crow has the ability to recognize geometric regularity. In their study published in the journal Science Advances, Philipp Schmidbauer, Madita Hahn and Andreas Nieder conducted several experiments that involved testing crows on their ability to recognize geometric shapes.

What Is Typology? A New Independent Field?

What is typology? There are many typologies for different existing subjects. But the word “typology” means “finding a type” or “finding the fact”. Some people have abilities to see the real facts a…
