Cooperation of active steering control of wheelsets with subsystems of an autonomous urban rail vehicle

open access: yesActa Polytechnica CTU Proceedings, 2023
The paper presents the motivations for the application of actively controlled elements in the running gear of a rail vehicle and the challenges that need to be addressed before deploying vehicles with actively controlled elements in real operation ...

The progenitor mass of the magnetar SGR1900+14 [PDF]

open access: yes, 2009
Magnetars are young neutron stars with extreme magnetic fields (B > 10^{14}-10^{15}G). How these fields relate to the properties of their progenitor stars is not yet clearly established. However, from the few objects associated with young clusters it has

No Fossil Disk in the T Tauri Multiple System V773 Tau [PDF]

open access: yes, 2003
We present new multi-epoch near-infrared and optical high-angular images of the V773 Tau pre-main sequence triple system, a weak-line T Tauri (WTTS) system in which the presence of an evolved, ``fossil'' protoplanetary disk has been inferred on the basis

Novel Applicators for Local Microwave Hyperthermia Based on Zeroth-Order Mode Resonator Metamaterial

open access: yesInternational Journal of Antennas and Propagation, 2014
It is demonstrated that a theory of zero-order mode resonator (ZOR) metamaterial (MTM) structure can be used for the development of a novel class of applicators for microwave thermotherapy, for example, for hyperthermia in cancer treatment or for ...

Making the most of clade selection [PDF]

open access: yes, 2017
Clade selection is unpopular with philosophers who otherwise accept multilevel selection theory. Clades cannot reproduce, and reproduction is widely thought necessary for evolution by natural selection, especially of complex adaptations.

Space Velocities of L- and T-type Dwarfs [PDF]

open access: yes, 2007
(Abridged) We have obtained radial velocities of a sample of 18 ultracool dwarfs (M6.5-T8) using high-resolution, near-infrared spectra obtained with NIRSPEC and the Keck II telescope.
