The object of research is a pneumatic spring of high-speed rolling stock of the railway. The method of experimental static testing of a pneumatic spring of high-speed rolling stock is presented. Based on experimental tests, the “force-strain” dependences of a pneumatic spring are obtained when the pressure gauge in the pneumatic spring changes from...

In various parts of the globe, there have been several earthquakes of a modest size. Monitoring the change of the points over time is a key component of typical techniques for extracting dynamic responses. This technique was unable to completely extract all of the earthquake’s dynamic properties. The GNSS precise point positioning (PPP) may be a us...

Single-turn coil (STC) is a destructive pulse magnet aiming at 100–300 T ultra-high magnetic field. In this study, a conductor shock dynamics model based on the hardening and thermal softening effects is proposed for STCs. Using this model, the changes in mechanical parameters of the conductor during discharge are investigated. The results show tha...

Cílem práce je seznámit se a matematicky popsat jednu z hypoteticky nejzávažnějších havárií vysokotlakého jaderného reaktoru. Úvodem je stručně popsaná havárie se ztrátou chladiva (LOCA), související s rozpínání materiálu na bázi zirkonia v palivových tyčích. Tento jev je popsán zákony zachování příslušných veličin v podobě parciálních diferenciáln...

Weakly nonlocal (WNL) Quantum Field Theories (QFT's) may define a new class of UV-completions in particle physics and gravity, without introducing any new elementary particle. One problematic issue is how to realize spontaneous symmetry breaking without introducing an infinite tower of ghosts in the perturbative spectrum. In this article, a WNL ext...

This article analyses the effects of deformation on the structure of CMnSi steel at various deformation levels. After hot forging, the structure of CMnSi steel comprises coarse-sized alpha and pearlite particles. The average grain size of steel after forging was 100 μm. After hot rolling, the grain size gradually decreases, with the average size of...

In this study TC4/TC17 titanium alloy dissimilar joints were obtained via vacuum electron beam welding. The compressive behavior of base metals and joint at different strain levels was studied, along with microstructural and fracture surface observations. The true stress–strain curves of base metals and joint at different strains demonstrated smoot...

Witten's open string field theory with a generalized version of stubs is reformulated as a cubic string field theory using an auxiliary string field. The gauge symmetries and equations of motion as well as the associative algebra of the resulting theory are investigated. Integrating out either the original or auxiliary field is shown to recover the...
