In global studies, the Earth's gravitational field is conveniently described in terms of spherical harmonics. The solution to a gravitational curvature boundary-value problem canould formally be formulated for the vertical-vertical-vertical, vertical-vertical-horizontal, vertical-horizontal-horizontal and horizontal-horizontal...

Since marine seismic studies are relatively sparse and unevenly distributed, detailed tomographic images of the Moho geometry under large parts of the world’s oceans and marginal seas are not yet available. Marine gravity data is, therefore, often used to detect the Moho depth in&#...

Nowadays, the accessibility of digitized historical documents is extremely important to facilitate fast and efficient retrieval of historical information and knowledge extraction from such data. To provide such functionality, it is necessary to convert document images into plain text using optica...

Despite the wide choice of commercial heart valve prostheses, cryopreserved semilunar allograft heart valves (C-AHV) are required, and successfully transplanted in selected groups of patients. The expiration limit (EL) criteria have not been defined yet. Most Tissue Establishments (TE) use the&#x...

Liver is frequently injured in blunt abdominal trauma caused by road traffic accidents. The testing of safety performance of vehicles, e.g. belt usage, head support, seat shape, or air bag shape, material, pressure, and reaction, could lead to reduction of the injury seriousness. C...

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....

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. ...

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...

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 ...

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...

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&#...

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...

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.

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 ...
