Fungi Recognition: A Practical Use Case

The paper presents a system for visual recognition of1394 fungi species based on deep convolutional neuralnetworks and its deployment in a citizen-science project.The system allows users to automatically identify observedspecimens, while providing valuable data to biologists andcomputer vision researchers....

Effects of Imperfect Grooves in Full-Floating Ring Bearings on Dynamics of a Turbocharger Rotor

Full-floating ring bearings cause nonlinear vibrations of turbocharger rotors, and they have higher hydrodynamic power losses in comparison with rolling element bearings. Both issues can be improved if several shallow axial grooves are machined in the inner surface of the floating ring. ...

RETIS - Real-Time Sensitive Wireless Communication Solution for Industrial Control Applications

Ultra-Reliable Low Latency Communications (URLLC) has been always a vital component of many industrial applications. The paper proposes a new wireless URLLC solution called RETIS, which is suitable for factory automation and fast process control applications, where low latency, low jitter, a...

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 ...
