Air-entrainment as an alternative to polypropylene fibers and its effect on the compressive strength of concrete at high temperatures
(IOP Publishing Ltd, 2019)
Although much research has been done in the area of the fire response of concrete in the past decades, only few studies are focused on the mechanical properties of air-entrained concrete at high temperatures. This paper ...
Analysis of self-similar rate-dependent interfacial crack propagation in mode II
(Springer, 2019)
The present study analyzes the fundamental properties of a rate-dependent cohesive model applied to
the description of dynamic mode-II crack propagation. To make a semi-analytical treatment possible, the idealised
problem ...
Discrete analysis on non-cubic lattices
(IOP Publishing Ltd., 2019)
The paper proposes practical and computation methods for discrete analysis of functions defined on the weight lattices or model sets of semisimple Lie groups. They are entirely group theoretical, being based on finite ...
Crack growth in Fe-Si (2 wt%) single crystals on macroscopic and atomistic level
(Elsevier, 2019)
This paper is dedicated to experimental and atomistic study of the influence of so called T-stress (acting along the
crack plane) on fracture processes in bcc iron. We analyze experimental results from fracture tests ...
Impact of Pilots' Tiredness on the Outcome of Psychological Testing
(Wydawnictwo Politechniki Śląskiej, 2019)
Presented work is primarily oriented on the experimental verification of the influence of fatigue on the psychological condition of the flying personnel, using psychological and performance tests. For the evaluation of a ...
Improvement of Column-Parallel Sampling for A Monolithic Pixel Detector
(IOP Publishing Ltd, 2020)
Monolithic pixel detectors often use an on-chip analog to digital converter (ADC) with
successive approximation register (SAR) to digitize the signal amplitude of the pixels. This paper solves the challenges of column-parallel ...
Stabilized-load crystal oscillator
(FEE, Computer Science and Information Technology, Osijek, 2019)
The presence and concentration of some gases can be sensed by quartz crystal resonators covered by a thin layer of gas-absorbing material. The absorbed gas increases the inertial mass of the layer, and as a result the ...
SOM in Hilbert Space
(AV ČR, Ústav informatiky, 2019)
The self organization can be performed in an Euclidean space as usually denned or in any metric space which is generalization of previous one. Both approaches have advantages and disadvantages. A novel method of batch SOM ...
Numerical Simulation of Precast Concrete Panel for Airfield Pavement
(fib - fédération internationale du béton, 2019)
While the use of cast-in-place concrete for an airfield and highway pavement overlay is very common, the application of precast concrete elements is very limited because of two main reasons - high production costs and ...
Noise dependence on temperature in fluxgates with electroplated core
(Elsevier Science, 2016)
Samples of electrodeposited fluxgate sensors with varying magnetostriction coefficient were manufactured and their noise was studied at various temperatures. We show that the noise of the fluxgate is, under some conditions, ...
