Towards efficient and vibration-reducing full-floating ring bearings in turbochargers

Turbocharger rotors supported on full-floating ring bearings are highly nonlinear systems which are operated at high speeds. During operation, the rotor usually oscillates at sub-synchronous frequencies which result from fluid-induced instabilities. This work provides some suggestions for reducing the ...

The Biot-Darcy-Brinkman model of flow in deformable double porous media

In this paper we present the two-level homogenization of the flow in a deformable double-porous structure described at two characteristic scales. The higher level porosity associated with the mesoscopic structure is constituted by channels in a matrix made of a microporous material cons...

Do zámoří s Austro-Americanou

Croatian is poorly resourced and highly inflected language from Slavic language family. Nowadays, research is focusing mostly on English. We created a new word analogy dataset based on the original English Word2vec word analogy dataset and added some of the specific linguistic aspects&#...

On maximum and comparison principles for parabolic problems with the p-Laplacian

We investigate strong and weak versions of maximum and comparison principles for a class of quasilinear parabolic equations with the p-Laplacian ∂tu−Δpu=λ|u|p−2u+f(x,t) under zero boundary and nonnegative initial conditions on a bounded cylindrical domain Ω×(0,T), λ∈R, and f∈L∞(Ω×(0,T)). Several relat...

Vyšší Dimensional catenoid, Liouville rovnice a Allen-Cahn rovnice

We build a family of entire solutions to the Allen–Cahn equation in RN+1 for N≥3, whose zero level set approaches the higher-dimensional catenoid in a compact region and has two logarithmic ends governed by the solutions to the Liouville equation.

Impulsive control of conservative equations and systems: variational approach

Using the variational structure of the second order periodic problems we find an optimal impulsive control which forces the conservative system into a periodic motion. In particular, our main results concern the system of charged planar pendulums with external disturbances and neglected ...
